  • Why is Apache seg faulting?

    - by Jamie Howard
    We have a production server that seems to Seg Fault a few times every day. The fault is picked up by Apache and logged in the error log - but there seems to be no traffic around the time. If it's a request generating the fault then it looks like it happens before any other logging is made so I can't see how it's happening so it's very hard to debug. Our setup is Linux 64 bit Centos 5.3 Apache is loaded with the following modules apachectl -t -D DUMP_MODULES | more Loaded Modules: core_module (static) mpm_prefork_module (static) http_module (static) so_module (static) auth_basic_module (shared) auth_digest_module (shared) authn_file_module (shared) authn_alias_module (shared) authn_anon_module (shared) authn_dbm_module (shared) authn_default_module (shared) authz_host_module (shared) authz_user_module (shared) authz_owner_module (shared) authz_groupfile_module (shared) authz_dbm_module (shared) authz_default_module (shared) ldap_module (shared) authnz_ldap_module (shared) include_module (shared) log_config_module (shared) logio_module (shared) env_module (shared) ext_filter_module (shared) mime_magic_module (shared) expires_module (shared) deflate_module (shared) headers_module (shared) usertrack_module (shared) setenvif_module (shared) mime_module (shared) dav_module (shared) status_module (shared) autoindex_module (shared) info_module (shared) dav_fs_module (shared) vhost_alias_module (shared) negotiation_module (shared) dir_module (shared) actions_module (shared) speling_module (shared) userdir_module (shared) alias_module (shared) rewrite_module (shared) proxy_module (shared) proxy_balancer_module (shared) proxy_ftp_module (shared) proxy_http_module (shared) proxy_connect_module (shared) cache_module (shared) suexec_module (shared) disk_cache_module (shared) file_cache_module (shared) mem_cache_module (shared) cgi_module (shared) version_module (shared) security2_module (shared) unique_id_module (shared) fcgid_module (shared) php5_module (shared) proxy_ajp_module (shared) ssl_module (shared) Here's an exert from the Apache error log: [Mon Mar 15 06:39:25 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 07:41:31 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 08:24:16 2010] [error] [client 67.19.250.146] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 08:43:46 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 08:54:02 2010] [error] [client 74.208.123.71] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 09:09:51 2010] [notice] child pid 2138 exit signal Segmentation fault (11), possible coredump in /tmp [Mon Mar 15 09:45:27 2010] [error] [client 213.246.222.74] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind:) [Mon Mar 15 09:49:05 2010] [error] [client 190.12.113.196] File does not exist: /var/www/vhosts/default/htdocs/phpMyAdmin [Mon Mar 15 09:49:06 2010] [error] [client 190.12.113.196] File does not exist: /var/www/vhosts/default/htdocs/PMA And the Access log around the same time (09:09:51): 213.246.222.74 - - [15/Mar/2010:08:43:46 +0000] "GET /" 400 561 "-" "-" 208.80.193.28 - - [15/Mar/2010:08:52:20 +0000] "GET / HTTP/1.0" 301 313 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; SU 2.009)" 74.208.123.71 - - [15/Mar/2010:08:54:02 +0000] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 298 "-" "-" 81.149.146.231 - - [15/Mar/2010:09:15:18 +0000] "GET /zabbix/ HTTP/1.1" 200 3565 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_2; en-us) AppleWebKit/531.21.8 (KHTML, like Gecko) Version/4.0.4 Safari/531.21.10" 81.158.71.196 - - [15/Mar/2010:09:16:06 +0000] "GET / HTTP/1.1" 301 313 "-" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.0.18) Gecko/2010020219 Firefox/3.0.18" 213.246.222.74 - - [15/Mar/2010:09:45:27 +0000] "GET /" 400 561 "-" "-" 213.246.222.74 - - [15/Mar/2010:09:45:27 +0000] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 298 "-" "-" 190.12.113.196 - - [15/Mar/2010:09:49:05 +0000] "GET /phpMyAdmin/main.php HTTP/1.0" 404 295 "-" "-" So As you can see, there's no access logged around the time of the fault!!

Really appreciate any help! Cheers!

  • How to merge two different Makefiles?

    - by martijnn2008
    I have did some reading on "Merging Makefiles", one suggest I should leave the two Makefiles separate in different folders [1]. For me this look counter intuitive, because I have the following situation: I have 3 source files (main.cpp flexibility.cpp constraints.cpp) one of them (flexibility.cpp) is making use of the COIN-OR Linear Programming library (Clp) When installing this library on my computer it makes sample Makefiles, which I have adjust the Makefile and it currently makes a good working binary. # Copyright (C) 2006 International Business Machines and others. # All Rights Reserved. # This file is distributed under the Eclipse Public License. # $Id: Makefile.in 726 2006-04-17 04:16:00Z andreasw $ ########################################################################## # You can modify this example makefile to fit for your own program. # # Usually, you only need to change the five CHANGEME entries below. # ########################################################################## # To compile other examples, either changed the following line, or # add the argument DRIVER=problem_name to make DRIVER = main # CHANGEME: This should be the name of your executable EXE = clp # CHANGEME: Here is the name of all object files corresponding to the source # code that you wrote in order to define the problem statement OBJS = $(DRIVER).o constraints.o flexibility.o # CHANGEME: Additional libraries ADDLIBS = # CHANGEME: Additional flags for compilation (e.g., include flags) ADDINCFLAGS = # CHANGEME: Directory to the sources for the (example) problem definition # files SRCDIR = . ########################################################################## # Usually, you don't have to change anything below.

I don't know what they exactly do. What I want is to merge the two of them so I get only one binary. The code compiled in the second Makefile should be the result. I want to add flexibility.cpp and constraints.cpp to the second Makefile, but when I do. I get the problem following problem: flexibility.h:4:26: fatal error: ClpSimplex.hpp: No such file or directory #include "ClpSimplex.hpp" So the compiler can't find the Clp library. I also tried to copy-paste more code from the first Makefile into the second, but it still gives me that same error. Q: Can you please help me with merging the two makefiles or pointing out a more elegant way? Q: In this case is it indeed better to merge the two Makefiles? I also tried to use cmake, but I gave upon that one quickly, because I don't know much about flex and bison.

  • Qt - drag and drop with graphics view framework

    - by David Davidson
    I'm trying to make a simple draggable item using the graphics framework. Here's the code for what I did so far: Widget class: class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); }; Widget::Widget(QWidget *parent) : QWidget(parent) { DragScene *scene = new DragScene(); DragView *view = new DragView(); QHBoxLayout *layout = new QHBoxLayout(); DragItem *item = new DragItem(); view->setAcceptDrops(true); scene->addItem(item); view->setScene(scene); layout->addWidget(view); this->setLayout(layout); } Widget::~Widget() { } DragView class: class DragView : public QGraphicsView { public: DragView(QWidget *parent = 0); }; DragView::DragView(QWidget *parent) : QGraphicsView(parent) { setRenderHints(QPainter::Antialiasing); } DragScene class: class DragScene : public QGraphicsScene { public: DragScene(QObject* parent = 0); protected: void dragEnterEvent(QGraphicsSceneDragDropEvent *event); void dragMoveEvent(QGraphicsSceneDragDropEvent *event); void dragLeaveEvent(QGraphicsSceneDragDropEvent *event); void dropEvent(QGraphicsSceneDragDropEvent *event); }; DragScene::DragScene(QObject* parent) : QGraphicsScene(parent) { } void DragScene::dragEnterEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragMoveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragLeaveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dropEvent(QGraphicsSceneDragDropEvent *event){ qDebug() << event->pos(); event->acceptProposedAction(); DragItem *item = new DragItem(); this->addItem(item); item->setPos(event->pos()); } DragItem class: class DragItem : public QGraphicsItem { public: DragItem(QGraphicsItem *parent = 0); QRectF boundingRect() const; void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = 0); protected: void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event); void mouseMoveEvent(QGraphicsSceneMouseEvent *event); void mousePressEvent(QGraphicsSceneMouseEvent *event); void mouseReleaseEvent(QGraphicsSceneMouseEvent *event); }; DragItem::DragItem(QGraphicsItem *parent) : QGraphicsItem(parent) { setFlag(QGraphicsItem::ItemIsMovable); } QRectF DragItem::boundingRect() const{ const QPointF *p0 = new QPointF(-10,-10); const QPointF *p1 = new QPointF(10,10); return QRectF(*p0,*p1); } void DragItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget){ if(painter == 0) painter = new QPainter(); painter->drawEllipse(QPoint(0,0),10,10); } void DragItem::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mousePressEvent(QGraphicsSceneMouseEvent *event){ QMimeData* mime = new QMimeData(); QDrag* drag = new QDrag(event->widget()); drag->setMimeData(mime); drag->exec(); } void DragItem::mouseReleaseEvent(QGraphicsSceneMouseEvent *event){ } main.cpp instantiates a Widget and shows it. When I try to drag the circle, the app just creates another circle over the original one, regardless of where I release the drag. qDebug() in DragScene's dropEvent() shows QPointF(0,0) everytime the drag ends. I'm having a hard time trying to understand exactly what I have to do, which classes I should subclass, which methods needs to be overriden, to make this work. The documentation on this isn't very detailed. I'd like to know how to make this work, and if there's some other, more comprehensive resource to learn about the graphics view framework, besides the official documentation (which is excellent btw, but it would be great if there was a more detailed treatise on the subject). EDIT: Following badgerr's advice, I replaced item-pos() in DragScene::dropEvent() with item-scenePos(), now the drop event creates a new circle in the drop site, which is more or less what I wanted. But the original circle is still in place, and while the drag is in progress, the item doesn't follow the mouse cursor. The QGraphicsSceneDragDropEvent documentation says that pos() should return the cursor position in relation to the view that sent the event, which, unless I got it wrong, shouldn't be (0,0) all the time. Weird. I've read in a forum post that you can use QDrag::setPixMap() to show something during the drag, and in examples I've seen pictures being set as pixmaps, but how do I make the pixmap just like the graphics item I'm supposed to be dragging?

  • Prefer extension methods for encapsulation and reusability?

    - by tzaman
    edit4: wikified, since this seems to have morphed more into a discussion than a specific question. In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. (edit: Even in the current .NET library, I can see places where it would've been useful to have extensions instead of instance methods - for example, all of the utility functions of List<T> (Sort, BinarySearch, FindIndex, etc.) would be incredibly useful if they were lifted up to IList<T> - getting free bonus functionality like that adds a lot more benefit to implementing the interface.) So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself? (edit2: In response to Tomas - while C# did start out with Java's (overly, imo) OO mentality, it seems to be embracing more multi-paradigm programming with every new release; the main thrust of this question is whether using extension methods to drive a style change (towards more generic / functional C#) is useful or worthwhile..) edit3: overridable extension methods The only real problem identified so far with this approach, is that you can't specialize extension methods if you need to. I've been thinking about the issue, and I think I've come up with a solution. Suppose I have an interface MyInterface, which I want to extend - I define my extension methods in a MyExtension static class, and pair it with another interface, call it MyExtensionOverrider. MyExtension methods are defined according to this pattern: public static int MyMethod(this MyInterface obj, int arg, bool attemptCast=true) { if (attemptCast && obj is MyExtensionOverrider) { return ((MyExtensionOverrider)obj).MyMethod(arg); } // regular implementation here } The override interface mirrors all of the methods defined in MyExtension, except without the this or attemptCast parameters: public interface MyExtensionOverrider { int MyMethod(int arg); string MyOtherMethod(); } Now, any class can implement the interface and get the default extension functionality: public class MyClass : MyInterface { ... } Anyone that wants to override it with specific implementations can additionally implement the override interface: public class MySpecializedClass : MyInterface, MyExtensionOverrider { public int MyMethod(int arg) { //specialized implementation for one method } public string MyOtherMethod() { // fallback to default for others MyExtension.MyOtherMethod(this, attemptCast: false); } } And there we go: extension methods provided on an interface, with the option of complete extensibility if needed. Fully general too, the interface itself doesn't need to know about the extension / override, and multiple extension / override pairs can be implemented without interfering with each other. I can see three problems with this approach - It's a little bit fragile - the extension methods and override interface have to be kept synchronized manually. It's a little bit ugly - implementing the override interface involves boilerplate for every function you don't want to specialize. It's a little bit slow - there's an extra bool comparison and cast attempt added to the mainline of every method. Still, all those notwithstanding, I think this is the best we can get until there's language support for interface functions. Thoughts?

  • How can I connect to a mail server using SMTP over SSL using Python?

    - by jakecar
    Hello, So I have been having a hard time sending email from my school's email address. It is SSL and I could only find this code online by Matt Butcher that works with SSL: import smtplib, socket version = "1.00" all = ['SMTPSSLException', 'SMTP_SSL'] SSMTP_PORT = 465 class SMTPSSLException(smtplib.SMTPException): """Base class for exceptions resulting from SSL negotiation.""" class SMTP_SSL (smtplib.SMTP): """This class provides SSL access to an SMTP server. SMTP over SSL typical listens on port 465. Unlike StartTLS, SMTP over SSL makes an SSL connection before doing a helo/ehlo. All transactions, then, are done over an encrypted channel. This class is a simple subclass of the smtplib.SMTP class that comes with Python. It overrides the connect() method to use an SSL socket, and it overrides the starttles() function to throw an error (you can't do starttls within an SSL session).

  • "Phased" execution of functions in javascript

    - by FK82
    Hey there! This is my first post on stackoverflow, so please don't flame me too hard if I come across like a total nitwit or if I'm unable ot make myself perfectly clear. :-) Here's my problem: I'm trying to write a javascript function that "ties" two functions to another by checking the first one's completion and then executing the second one. The easy solution to this obviously would be to write a meta function that calls both functions within it's scope. However, if the first function is asynchronous (specifically an AJAX call) and the second function requires the first one's result data, that simply won't work. My idea for a solution was to give the first function a "flag", i.e. making it create a public property "this.trigger" (initialized as "0", set to "1" upon completion) once it is called; doing that should make it possible for another function to check the flag for its value ([0,1]). If the condition is met ("trigger == 1") the second function should get called. The following is an abstract example code that I have used for testing: <script type="text/javascript" > /**/function cllFnc(tgt) { //!! first function this.trigger = 0 ; var trigger = this.trigger ; var _tgt = document.getElementById(tgt) ; //!! changes the color of the target div to signalize the function's execution _tgt.style.background = '#66f' ; alert('Calling! ...') ; setTimeout(function() { //!! in place of an AJAX call, duration 5000ms trigger = 1 ; },5000) ; } /**/function rcvFnc(tgt) { //!! second function that should get called upon the first function's completion var _tgt = document.getElementById(tgt) ; //!! changes color of the target div to signalize the function's execution _tgt.style.background = '#f63' ; alert('... Someone picked up!') ; } /**/function callCheck(obj) { //alert(obj.trigger ) ; //!! correctly returns initial "0" if(obj.trigger == 1) { //!! here's the problem: trigger never receives change from function on success and thus function two never fires alert('trigger is one') ; return true ; } else if(obj.trigger == 0) { return false ; } } /**/function tieExc(fncA,fncB,prms) { if(fncA == 'cllFnc') { var objA = new cllFnc(prms) ; alert(typeof objA + '\n' + objA.trigger) ; //!! returns expected values "object" and "0" } //room for more case definitions var myItv = window.setInterval(function() { document.getElementById(prms).innerHTML = new Date() ; //!! displays date in target div to signalize the interval increments var myCallCheck = new callCheck(objA) ; if( myCallCheck == true ) { if(fncB == 'rcvFnc') { var objB = new rcvFnc(prms) ; } //room for more case definitions window.clearInterval(myItv) ; } else if( myCallCheck == false ) { return ; } },500) ; } </script> The HTML part for testing: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/strict.dtd > <html> <head> <script type="text/javascript" > <!-- see above --> </script> <title> Test page </title> </head> <body> <!-- !! testing area --> <div id='target' style='float:left ; height:6em ; width:8em ; padding:0.1em 0 0 0; font-size:5em ; text-align:center ; font-weight:bold ; color:#eee ; background:#fff;border:0.1em solid #555 ; -webkit-border-radius:0.5em ;' > Test Div </div> <div style="float:left;" > <input type="button" value="tie calls" onmousedown="tieExc('cllFnc','rcvFnc','target') ;" /> </div> <body> </html> I'm pretty sure that this is some issue with javascript scope as I have checked whether the trigger gets set to "1" correctly and it does. Very likely the "checkCall()" function does not receive the updated object but instead only checks its old instance which obviously never flags completion by setting "this.trigger" to "1". If so I don't know how to address that issue. Anyway, hope someone has an idea or experience with this particular kind of problem. Thanks for reading! FK

  • strange output in ubuntu terminal when running a lex program

    - by Max
    Hi. I'm running a lexical analyzer using lex, and I've got it mostly correct, but my terminal gives strange output once I take out an ECHO statement I was using to help debug the code. With that statement, my output looks like this: max@Max-Ubuntu:~/Desktop/Compiler Project/project2$ ./a.out <../cmmFiles/expression.cmm VOIDID(){ INTID,ID,ID; BOOLID,ID,ID; ID(ID); ID(ID); ID(ID); ID(ID); ID=-ID-NUM+ID/NUM*(-NUM+ID*IDNUM); ID(ID); ID=ID>ID||ID>=ID; IF(ID)ID(NUM);ELSEID(NUM); ID=ID<ID&&ID<=ID; IF(ID==TRUE)ID(NUM);ELSEID(NUM); ID=ID&&!ID||!ID&&ID; IF(ID!=FALSE)ID(NUM);ELSEID(NUM); } While hard to read, that output is correct. Once I take out the ECHO statement, I instead get this: max@Max-Ubuntu:~/Desktop/Compiler Project/project2$ ./a.out <../cmmFiles/expression.cmm }F(ID!=FALSE)ID(NUM);ELSEID(NUM);; It looks like it's only outputting the final line, except with an extraneous } near the beginning, what looks like half an IF token immediately after, and an extraneous ; at the end. Is this some quirk of my terminal, or does removing that ECHO cause my lexer to screw up that badly? I'm hesitant to keep working until I know for sure what's going on here. Thanks for any answers. Here's my lexer: %{ /* definitions of manifest constants -reserved words- BOOL, ELSE, IF, TRUE, WHILE, DO, FALSE, INT, VOID -Punctuation and operators- LPAREN, RPAREN, LBRACK, RBRACK, LBRACE, RBRACE, SEMI, COMMA, PLUS, MINUS, TIMES, DIV, MOD, AND, OR, NOT, IS, ADDR, EQ, NE, LT, GT, LE, GE -Other tokens- NUMBER, ID, PUNCT, OP */ #include <stdio.h> #include <stdlib.h> //#include "y.tab.h" //int line = 1, numAttr; //char *strAttr; %} /* regular definitions */ delim [ \t] ws {delim}+ start "/*" one [^*] two "*" three [^*/] end "/" comment {start}({one}*{two}+{three})*{one}*{two}+{end} letter [A-Za-z] digit [0-9] id ({letter}|_)({letter}|{digit}|_)* number {digit}+ %% {ws} { /*no action and no return */} {comment} { /*no action and no return */} [\n] {ECHO; /*no action */} // <-- this is the ECHO in question. bool { printf("BOOL");} else { printf("ELSE");} if { printf("IF");} true { printf("TRUE");} while { printf("WHILE");} do { printf("DO");} false { printf("FALSE");} int { printf("INT");} void { printf("VOID");} {id} { printf("ID");} {number} { printf("NUM");} "(" { printf("(");} ")" { printf(")");} "[" { printf("[");} "]" { printf("]");} "{" { printf("{");} "}" { printf("}");} ";" { printf(";");} "," { printf(",");} "+" { printf("+");} "-" { printf("-");} "*" { printf("*");} "/" { printf("/");} "%" { printf("%");} "&" { printf("&");} "&&" { printf("&&");} "||" { printf("||");} "!" { printf("!");} "!=" { printf("!=");} "=" { printf("=");} "==" { printf("==");} "<" { printf("<");} "<=" { printf("<=");} ">" { printf(">");} ">=" { printf(">=");} %% int main() { yylex(); printf("\n"); } int yywrap(void) { return 1; } here's the file it's analyzing: /* this program * illustrates evaluation of * arithmetic and boolean * expressions */ void main( ) { int m,n,p; bool a,b,c; scan(m); print(m); scan(n); print(n); p=-m-3+n/2*(-5+m*n%4); print(p); a=m>n || n>=p; if (a) print(1); else print(0); b=m<n && n<=p; if (b==true) print(1); else print(0); c=a && !b || !a && b; if (c!=false) print(1); else print(0); }

I have placed one textbox(txtPassword) and one button(btnLogin) control in the Div which will be shown by the jQueryDialog.But in btnLogin's Click event, I am not able to read the Text value entered in the textbox txtPassword The below is my code <form id="form1" runat="server"> <div> <br /> <asp:TextBox ID="txtModelId" runat="server" Text=""></asp:TextBox><br /> <asp:Button ID="btnGo" runat="server" Text="Go" OnClick="btnGo_Click" /> <br /> <asp:Label ID="lblUserMsg" runat="server" Text="Label"></asp:Label></div> <div id="divContentHolder"> <div class="demo"> <div id="dialog" title="Login with your TradeIn Account"> <p id="validateTips">Enter your EmailId & password</p> <fieldset> <label for="email">Email</label> <asp:TextBox ID="txtEmail" CssClass="text ui-widget-content ui-corner-all" runat="server" ></asp:TextBox> <label for="password"> <asp:TextBox ID="TextBox1" runat="server" Text="sample"></asp:TextBox>Password</label> <asp:TextBox ID="txtPassword" CssClass="text ui-widget-content ui-corner-all" runat="server" ></asp:TextBox> <asp:Button ID="btnLogin" runat="server" Text="Login" OnClick="btnLogin_Click" UseSubmitBehavior="false"/> </fieldset> </div><!--dialog--> </div><!--demo--> </div><!--divContentHolder--> </form> Server side Code protected void btnGo_Click(object sender, EventArgs e) { CheckUserLoggedIn(); } private void CheckUserLoggedIn() { if (Session["username"] != null) { Response.Write("Logged in user"); ClientScript.RegisterHiddenField("isAuthenticated", "true"); } else { ClientScript.RegisterHiddenField("isAuthenticated", "false"); } } protected void btnLogin_Click(object sender, EventArgs e) { string txtSample= TextBox1.Text; // this is showing the value 'sample' string txtPass= txtPassword.Text; // this is showing null if (txtPass == "shyju") { Session["username"] = txtPassword.Text; Response.Redirect("TestingModal.aspx"); } } My java script code to render the dialog $(function() { var name = $("#name"), email = $("#email"), password = $("#password"), allFields = $([]).add(name).add(email).add(password), tips = $("#validateTips"); function updateTips(t) { tips.text(t).effect("highlight",{},1500); } function checkLength(o,n,min,max) { if ( o.val().length > max || o.val().length < min ) { o.addClass('ui-state-error'); updateTips("Length of " + n + " must be between "+min+" and "+max+"."); return false; } else { return true; } } function checkRegexp(o,regexp,n) { if ( !( regexp.test( o.val() ) ) ) { o.addClass('ui-state-error'); updateTips(n); return false; } else { return true; } } $("#dialog").dialog({ bgiframe: true, autoOpen: false, height: 300, modal: true, buttons: { 'Create an account': function() { var bValid = true; allFields.removeClass('ui-state-error'); bValid=true; if (bValid) { /*$('#users tbody').append('<tr>' + '<td>' + name.val() + '</td>' + '<td>' + email.val() + '</td>' + '<td>' + password.val() + '</td>' + '</tr>'); */ alert("Check User Credentials") $(this).dialog('close'); } }, Cancel: function() { $(this).dialog('close'); } }, close: function() { allFields.val('').removeClass('ui-state-error'); } }); $('#create-user').click(function() { $('#dialog').dialog('open'); }) .hover( function(){ $(this).addClass("ui-state-hover"); }, function(){ $(this).removeClass("ui-state-hover"); } ).mousedown(function(){ $(this).addClass("ui-state-active"); }) .mouseup(function(){ $(this).removeClass("ui-state-active"); }); var isAuthenticated = $("#isAuthenticated").val(); if (isAuthenticated && isAuthenticated == "false") { // Display the modal dialog. $("#dialog").dialog("open"); } }); I had hard coded the text properties value of TextBox1 as 'sample' in the HTML part of my ASPX file .In button click event i am getting it.But the other textbox,txtPassword 's Text property is giving me null value Please guide me to go ahead Thanks in advance

  • Pagination links broken - php/jquery

    - by ClarkSKent
    Hey, I'm still trying to get my pagination links to load properly dynamically. But I can't seem to find a solution to this one problem. vote down star Hi everyone, I am still trying to figure out how to fix my pagination script to work properly. the problem I am having is when I click any of the pagination number links to go the next page, the new content does not load. literally nothing happens and when looking at the console in Firebug, nothing is sent or loaded. I have on the main page 3 links to filter the content and display it. When any of these links are clicked the results are loaded and displayed along with the associated pagination numbers for that specific content. I believe the problem is coming from the sql query in generate_pagination.php (seen below). When I hard code the sql category part it works, but is not dynamic at all. This is why I'm calling $ids=$_GET['ids']; and trying to put that into the category section but then the numbers don't display at all. If I echo out the $ids variable and click on a filter it does display the correct name/id, so I don't know why this doesn't work Here is the main page so you can see how I am including and starting the function(I'm new to php): <?php include_once('generate_pagination.php'); ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" data-page="1"></div> <ul id="pagination"> <?php //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li class="page_numbers" id="page'.$i.'">'.$i.'</li>'; } ?> </ul> <br /> <br /> <a href="#" class="category" id="marketing">Marketing</a> <a href="#" class="category" id="automotive">Automotive</a> <a href="#" class="category" id="sports">Sports</a> Here is the generate pagination where the problem seems to occur: <?php $ids=$_GET['ids']; include_once('config.php'); $per_page = 3; //Calculating no of pages $sql = "SELECT COUNT(*) FROM explore WHERE category='$ids'"; $result = mysql_query($sql); $count = mysql_fetch_row($result); $pages = ceil($count[0]/$per_page); ?> I thought I might as well post the jquery script if someone wants to see: $(document).ready(function(){ //Display Loading Image function Display_Load() { $("#loading").fadeIn(900,0); $("#loading").html("<img src='bigLoader.gif' />"); } //Hide Loading Image function Hide_Load() { $("#loading").fadeOut('slow'); }; //Default Starting Page Results $("#pagination li:first").css({'color' : '#FF0084'}).css({'border' : 'none'}); Display_Load(); $("#content").load("pagination_data.php?page=1", Hide_Load()); // Editing below. // Sort content Marketing $("a.category").click(function() { Display_Load(); var this_id = $(this).attr('id'); $.get("pagination.php", { category: this.id }, function(data){ //Load your results into the page var pageNum = $('#content').attr('data-page'); $("#pagination").load('generate_pagination.php?category=' + pageNum +'&ids='+ this_id ); $("#content").load("filter_marketing.php?page=" + pageNum +'&id='+ this_id, Hide_Load()); }); }); //Pagination Click $("#pagination li").click(function(){ Display_Load(); //CSS Styles $("#pagination li") .css({'border' : 'solid #dddddd 1px'}) .css({'color' : '#0063DC'}); $(this) .css({'color' : '#FF0084'}) .css({'border' : 'none'}); //Loading Data var pageNum = $(this).attr("id").replace("page",""); $("#content").load("pagination_data.php?page=" + pageNum, function(){ $(this).attr('data-page', pageNum); Hide_Load(); }); }); }); If any could assist me on solving this problem that would be great, thanks.

  • NServiceBus pipeline with Distributors

    - by David
    I'm building a processing pipeline with NServiceBus but I'm having trouble with the configuration of the distributors in order to make each step in the process scalable. Here's some info: The pipeline will have a master process that says "OK, time to start" for a WorkItem, which will then start a process like a flowchart. Each step in the flowchart may be computationally expensive, so I want the ability to scale out each step. This tells me that each step needs a Distributor. I want to be able to hook additional activities onto events later. This tells me I need to Publish() messages when it is done, not Send() them. A process may need to branch based on a condition. This tells me that a process must be able to publish more than one type of message. A process may need to join forks. I imagine I should use Sagas for this. Hopefully these assumptions are good otherwise I'm in more trouble than I thought. For the sake of simplicity, let's forget about forking or joining and consider a simple pipeline, with Step A followed by Step B, and ending with Step C. Each step gets its own distributor and can have many nodes processing messages. NodeA workers contain a IHandleMessages processor, and publish EventA NodeB workers contain a IHandleMessages processor, and publish Event B NodeC workers contain a IHandleMessages processor, and then the pipeline is complete. Here are the relevant parts of the config files, where # denotes the number of the worker, (i.e. there are input queues NodeA.1 and NodeA.2): NodeA: <MsmqTransportConfig InputQueue="NodeA.#" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="NodeA.Distrib.Control" DistributorDataAddress="NodeA.Distrib.Data" > <MessageEndpointMappings> </MessageEndpointMappings> </UnicastBusConfig> NodeB: <MsmqTransportConfig InputQueue="NodeB.#" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="NodeB.Distrib.Control" DistributorDataAddress="NodeB.Distrib.Data" > <MessageEndpointMappings> <add Messages="Messages.EventA, Messages" Endpoint="NodeA.Distrib.Data" /> </MessageEndpointMappings> </UnicastBusConfig> NodeC: <MsmqTransportConfig InputQueue="NodeC.#" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="NodeC.Distrib.Control" DistributorDataAddress="NodeC.Distrib.Data" > <MessageEndpointMappings> <add Messages="Messages.EventB, Messages" Endpoint="NodeB.Distrib.Data" /> </MessageEndpointMappings> </UnicastBusConfig> And here are the relevant parts of the distributor configs: Distributor A: <add key="DataInputQueue" value="NodeA.Distrib.Data"/> <add key="ControlInputQueue" value="NodeA.Distrib.Control"/> <add key="StorageQueue" value="NodeA.Distrib.Storage"/> Distributor B: <add key="DataInputQueue" value="NodeB.Distrib.Data"/> <add key="ControlInputQueue" value="NodeB.Distrib.Control"/> <add key="StorageQueue" value="NodeB.Distrib.Storage"/> Distributor C: <add key="DataInputQueue" value="NodeC.Distrib.Data"/> <add key="ControlInputQueue" value="NodeC.Distrib.Control"/> <add key="StorageQueue" value="NodeC.Distrib.Storage"/> I'm testing using 2 instances of each node, and the problem seems to come up in the middle at Node B. There are basically 2 things that might happen: Both instances of Node B report that it is subscribing to EventA, and also that NodeC.Distrib.Data@MYCOMPUTER is subscribing to the EventB that Node B publishes. In this case, everything works great. Both instances of Node B report that it is subscribing to EventA, however, one worker says NodeC.Distrib.Data@MYCOMPUTER is subscribing TWICE, while the other worker does not mention it. In the second case, which seem to be controlled only by the way the distributor routes the subscription messages, if the "overachiever" node processes an EventA, all is well. If the "underachiever" processes EventA, then the publish of EventB has no subscribers and the workflow dies. So, my questions: Is this kind of setup possible? Is the configuration correct? It's hard to find any examples of configuration with distributors beyond a simple one-level publisher/2-worker setup. Would it make more sense to have one central broker process that does all the non-computationally-intensive traffic cop operations, and only sends messages to processes behind distributors when the task is long-running and must be load balanced? Then the load-balanced nodes could simply reply back to the central broker, which seems easier. On the other hand, that seems at odds with the decentralization that is NServiceBus's strength. And if this is the answer, and the long running process's done event is a reply, how do you keep the Publish that enables later extensibility on published events?

  • Problem deploying servlets in JBoss 5.1 on eclipse.

    - by Jeremy Goodell
    Yesterday I created a simple image servlet and attempted to deploy it. I am getting an error on JBoss startup, and then further errors on trying to invoke the servlet. I spent about 8 hours yesterday searching the web for answers and trying different scenarios. I ended up making my JBoss problems worse and then fixing them, but I never did get the servlet to work. The servlet is com.controller.MyImageServlet, and looks like this: package com.controller; import javax.servlet.http.*; /** * Servlet implementation class MyImageServlet */ public class MyImageServlet extends HttpServlet { private static final long serialVersionUID = 1L; public MyImageServlet() { super(); } // Process the HTTP Get request public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { /* ... */ } } The tags I've added to web.xml looks like this: <servlet> <servlet-name>ImageServlet</servlet-name> <servlet-class>com.controller.MyImageServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>ImageServlet</servlet-name> <url-pattern>/CERTIMAGE/*</url-pattern> </servlet-mapping> On server startup, this is the only indication in the log that something is amiss: 01:59:25,328 WARN [JAXWSDeployerHookPreJSE] Cannot load servlet class: com.controller.MyImageServlet When I try the URL pattern (http://localhost:9980/CERTIMAGE/1), I get the following stack trace in the log (and in the Browser): 01:59:39,640 INFO [[/]] Marking servlet ImageServlet as unavailable 01:59:39,640 ERROR [[ImageServlet]] Allocate exception for servlet ImageServlet java.lang.ClassNotFoundException: com.controller.MyImageServlet at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) at org.jboss.web.tomcat.service.TomcatInjectionContainer.newInstance(TomcatInjectionContainer.java:262) at org.jboss.web.tomcat.service.TomcatInjectionContainer.newInstance(TomcatInjectionContainer.java:256) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1006) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:777) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:129) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:190) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:92) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) If I try the URL pattern again, I get the following message in the log: 09:33:32,390 INFO [[ImageServlet]] Servlet ImageServlet is currently unavailable I have verified that MyImageServlet.class is in the WAR at WEB-INF/classes/com/controller/images. As a matter of fact, I even added some code to one of my JSPs to attempt to instantiate the Servlet and call the doGet method. This actually works and outputs the correct debug sequences to the log indicating that the Servlet constructor and doGet methods were called. I also tried following some instructions for creating/deploying a very simple HelloWorld servlet, and that has exactly the same problem. Note that web.xml already contained a servlet put there by JBoss: org.jboss.web.tomcat.service.StatusServlet -- that Servlet does not give any errors in the log. As an experiment, I removed ".web" from that path and ended up getting exactly the same error as I'm getting on my Servlet. So it would appear that JBoss is not able to locate my Servlet given the specified path. Just for kicks, I've tried all sorts of other paths, like just plain MyImageServlet, controller.MyImageServlet, and more. Also, the servlet was originally named ImageServlet, but I attempted the name change thinking maybe there was some conflict with an existing ImageServlet. In all cases, the behavior is the same. After all of my research yesterday, I would say that this appears to be a problem with the JBoss servlet container, and I also learned that JBoss 5.1.0.GA should come bundled with a tomcat servlet container. I installed JBoss on my PC (Windows XP) myself less than 2 months ago (from jboss.org) and used it pretty much as is. Note that I am running on JDK 1.6, so I did use the jboss-jdk6 installation version. I am running on Windows, but I also deploy to a Linux virtual dedicated server. I deployed the current version of my program, including the servlet to the Linux box, but I get the exact same errors. I'm reluctant to just try reinstalling JBoss, since it's hard to place the blame on the JBoss installation when I get the same errors on two completely different installations. I am a bit suspicious of the bundled tomcat servlet container, because using eclipse, I haven't been able to locate any indication that there is a tomcat bundled into JBoss. I did locate servlet-api.jar in the JBoss common/lib directory. This is on the eclipse build path. One possibly useful note: I had previously used a standalone tomcat server for other projects using the same eclipse, so maybe it's some sort of eclipse issue? But, as I said, I do get the same errors when I deploy to the Linux server, and that deployment process just involves ftping files to the server and then putting them into the deployed war package and restarting JBoss. Thanks for any help you can provide.

  • Fast multi-window rendering with C#

    - by seb
    I've been searching and testing different kind of rendering libraries for C# days for many weeks now. So far I haven't found a single library that works well on multi-windowed rendering setups. The requirement is to be able to run the program on 12+ monitor setups (financial charting) without latencies on a fast computer. Each window needs to update multiple times every second. While doing this CPU needs to do lots of intensive and time critical tasks so some of the burden has to be shifted to GPUs. That's where hardware rendering steps in, in another words DirectX or OpenGL. I have tried GDI+ with windows forms and figured it's way too slow for my needs. I have tried OpenGL via OpenTK (on windows forms control) which seemed decently quick (I still have some tests to run on it) but painfully difficult to get working properly (hard to find/program good text rendering libraries). Recently I tried DirectX9, DirectX10 and Direct2D with Windows forms via SharpDX. I tried a separate device for each window and a single device/multiple swap chains approaches. All of these resulted in very poor performance on multiple windows. For example if I set target FPS to 20 and open 4 full screen windows on different monitors the whole operating system starts lagging very badly. Rendering is simply clearing the screen to black, no primitives rendered. CPU usage on this test was about 0% and GPU usage about 10%, I don't understand what is the bottleneck here? My development computer is very fast, i7 2700k, AMD HD7900, 16GB ram so the tests should definitely run on this one. In comparison I did some DirectX9 tests on C++/Win32 API one device/multiple swap chains and I could open 100 windows spread all over the 4-monitor workspace (with 3d teapot rotating on them) and still had perfectly responsible operating system (fps was dropping of course on the rendering windows quite badly to around 5 which is what I would expect running 100 simultaneous renderings). Does anyone know any good ways to do multi-windowed rendering on C# or am I forced to re-write my program in C++ to get that performance (major pain)? I guess I'm giving OpenGL another shot before I go the C++ route... I'll report any findings here. Test methods for reference: For C# DirectX one-device multiple swapchain test I used the method from this excellent answer: Display Different images per monitor directX 10 Direct3D10 version: I created the d3d10device and DXGIFactory like this: D3DDev = new SharpDX.Direct3D10.Device(SharpDX.Direct3D10.DriverType.Hardware, SharpDX.Direct3D10.DeviceCreationFlags.None); DXGIFac = new SharpDX.DXGI.Factory(); Then initialized the rendering windows like this: var scd = new SwapChainDescription(); scd.BufferCount = 1; scd.ModeDescription = new ModeDescription(control.Width, control.Height, new Rational(60, 1), Format.R8G8B8A8_UNorm); scd.IsWindowed = true; scd.OutputHandle = control.Handle; scd.SampleDescription = new SampleDescription(1, 0); scd.SwapEffect = SwapEffect.Discard; scd.Usage = Usage.RenderTargetOutput; SC = new SwapChain(Parent.DXGIFac, Parent.D3DDev, scd); var backBuffer = Texture2D.FromSwapChain<Texture2D>(SC, 0); _rt = new RenderTargetView(Parent.D3DDev, backBuffer); Drawing command executed on each rendering iteration is simply: Parent.D3DDev.ClearRenderTargetView(_rt, new Color4(0, 0, 0, 0)); SC.Present(0, SharpDX.DXGI.PresentFlags.None); DirectX9 version is very similar: Device initialization: PresentParameters par = new PresentParameters(); par.PresentationInterval = PresentInterval.Immediate; par.Windowed = true; par.SwapEffect = SharpDX.Direct3D9.SwapEffect.Discard; par.PresentationInterval = PresentInterval.Immediate; par.AutoDepthStencilFormat = SharpDX.Direct3D9.Format.D16; par.EnableAutoDepthStencil = true; par.BackBufferFormat = SharpDX.Direct3D9.Format.X8R8G8B8; // firsthandle is the handle of first rendering window D3DDev = new SharpDX.Direct3D9.Device(new Direct3D(), 0, DeviceType.Hardware, firsthandle, CreateFlags.SoftwareVertexProcessing, par); Rendering window initialization: if (parent.D3DDev.SwapChainCount == 0) { SC = parent.D3DDev.GetSwapChain(0); } else { PresentParameters pp = new PresentParameters(); pp.Windowed = true; pp.SwapEffect = SharpDX.Direct3D9.SwapEffect.Discard; pp.BackBufferFormat = SharpDX.Direct3D9.Format.X8R8G8B8; pp.EnableAutoDepthStencil = true; pp.AutoDepthStencilFormat = SharpDX.Direct3D9.Format.D16; pp.PresentationInterval = PresentInterval.Immediate; SC = new SharpDX.Direct3D9.SwapChain(parent.D3DDev, pp); } Code for drawing loop: SharpDX.Direct3D9.Surface bb = SC.GetBackBuffer(0); Parent.D3DDev.SetRenderTarget(0, bb); Parent.D3DDev.Clear(ClearFlags.Target, Color.Black, 1f, 0); SC.Present(Present.None, new SharpDX.Rectangle(), new SharpDX.Rectangle(), HWND); bb.Dispose(); C++ DirectX9/Win32 API test with multiple swapchains and one device code is here: http://pastebin.com/tjnRvATJ It's a modified version from Kevin Harris's nice example code.

  • Can't get my head arround background workers in c#

    - by Connel
    I have wrote an application that syncs two folders together. The problem with the program is that it stops responding whilst copying files. A quick search of stack-overflow told me I need to use something called a background worker. I have read a few pages on the net about this but find it really hard to understand as I'm pretty new to programming. Below is the code for my application - how can I simply put all of the File.Copy(....) commands into their own background worker (if that's even how it works)? Below is the code for the button click event that runs the sub procedure and the sub procedure I wish to use a background worker on all the File.Copy lines. Button event: protected virtual void OnBtnSyncClicked (object sender, System.EventArgs e) { //sets running boolean to true booRunning=true; //sets progress bar to 0 prgProgressBar.Fraction = 0; //resets values used by progressbar dblCurrentStatus = 0;

  • How do you control what your C compiler Optimizes?

    - by Jordan S
    I am writing the firmware for an embedded device in C using the Silicon Labs IDE and the SDCC compiler. The device architecture is based on the 8051 family. The function in question is shown below. The function is used to set the ports on my MCU to drive a stepper motor. It gets called in by an interrupt handler. The big switch statement just sets the ports to the proper value for the next motor step. The bottom part of the function looks at an input from a hall effect sensor and a number of steps moved in order to detect if the motor has stalled. The problem is, for some reason the second IF statement that looks like this if (StallDetector > (GapSize + 20)) { HandleStallEvent(); } always seems to get optimized out. If I try to put a breakpoint at the HandleStallEvent() call the IDE gives me a message saying "No Address Correlation to this line number". I am not really good enough at reading assembly to tell what it is doing but I have pasted a snippet from the asm output below. Any help would be much appreciated. void OperateStepper(void) { //static bit LastHomeMagState = HomeSensor; static bit LastPosMagState = PosSensor; if(PulseMotor) { if(MoveDirection == 1) // Go clockwise { switch(STEPPER_POSITION) { case 'A': STEPPER_POSITION = 'B'; P1 = 0xFD; break; case 'B': STEPPER_POSITION = 'C'; P1 = 0xFF; break; case 'C': STEPPER_POSITION = 'D'; P1 = 0xFE; break; case 'D': STEPPER_POSITION = 'A'; P1 = 0xFC; break; default: STEPPER_POSITION = 'A'; P1 = 0xFC; } //end switch } else // Go CounterClockwise { switch(STEPPER_POSITION) { case 'A': STEPPER_POSITION = 'D'; P1 = 0xFE; break; case 'B': STEPPER_POSITION = 'A'; P1 = 0xFC; break; case 'C': STEPPER_POSITION = 'B'; P1 = 0xFD; break; case 'D': STEPPER_POSITION = 'C'; P1 = 0xFF; break; default: STEPPER_POSITION = 'A'; P1 = 0xFE; } //end switch } //end else MotorSteps++; StallDetector++; if(PosSensor != LastPosMagState) { StallDetector = 0; LastPosMagState = PosSensor; } else { if (PosSensor == ON) { if (StallDetector > (MagnetSize + 20)) { HandleStallEvent(); } } else if (PosSensor == OFF) { if (StallDetector > (GapSize + 20)) { HandleStallEvent(); } } } } //end if PulseMotor } ... and the asm output for the the bottom part of this function... ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:653: if(PosSensor != LastPosMagState) mov c,_P1_4 jb _OperateStepper_LastPosMagState_1_1,00158$ cpl c 00158$: jc 00126$ C$MotionControl.c$655$3$7 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:655: StallDetector = 0; clr a mov _StallDetector,a mov (_StallDetector + 1),a C$MotionControl.c$657$3$7 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:657: LastPosMagState = PosSensor; mov c,_P1_4 mov _OperateStepper_LastPosMagState_1_1,c ret 00126$: C$MotionControl.c$661$2$8 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:661: if (PosSensor == ON) jb _P1_4,00123$ C$MotionControl.c$663$4$9 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:663: if (StallDetector > (MagnetSize + 20)) mov a,_MagnetSize mov r2,a rlc a subb a,acc mov r3,a mov a,#0x14 add a,r2 mov r2,a clr a addc a,r3 mov r3,a clr c mov a,r2 subb a,_StallDetector mov a,r3 subb a,(_StallDetector + 1) jnc 00130$ C$MotionControl.c$665$5$10 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:665: HandleStallEvent(); ljmp _HandleStallEvent 00123$: C$MotionControl.c$668$2$8 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:668: else if (PosSensor == OFF) jnb _P1_4,00130$ C$MotionControl.c$670$4$11 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:670: if (StallDetector > (GapSize + 20)) mov a,#0x14 add a,_GapSize mov r2,a clr a addc a,(_GapSize + 1) mov r3,a clr c mov a,r2 subb a,_StallDetector mov a,r3 subb a,(_StallDetector + 1) jnc 00130$ C$MotionControl.c$672$5$12 ==. ; C:\SiLabs\Optec Programs\HSFW_HID_SDCC_2\MotionControl.c:672: HandleStallEvent(); C$MotionControl.c$678$2$1 ==.

Maybe it's just a dumb IDE!

  • Trying to get these list items to display inline

  • Why is the class wrong for NSFetchRequest?

    - by Stephen Furlani
    Hello, I am working with an undocumented API (Osirix) and I have a sister-question to the one I posted here. I am having trouble loading objects from a managed object context. With loading from API, using their instance of _context and _model 2010-05-28 14:05:13.588 OsiriX[44012:a0f] Entity: Study 2010-05-28 14:05:13.589 OsiriX[44012:a0f] EntityClassName: DicomStudy 2010-05-28 14:05:13.589 OsiriX[44012:a0f] ClassName: DicomStudy With loading from Fetch Request (and my own instance of _context, and _model) 2010-05-28 14:19:09.956 rcOsirix[44431:7a03] Entity: Study 2010-05-28 14:19:09.957 rcOsirix[44431:7a03] EntityClassName: DicomStudy 2010-05-28 14:19:09.958 rcOsirix[44431:7a03] ClassName: NSManagedObject output given by: NSLog(@"Entity: %@",[[item entity] name]); NSLog(@"EntityClassName: %@", [[item entity] managedObjectClassName]); NSLog(@"ClassName: %s", class_getName(object_getClass([item class]))); So it is obvious that even though the Entity thinks it is a DicomSeries - it is not. It is just a NSManagedObject. DicomSeries has some "hard-coded" KVC stuff that I ran into a problem with in my other question. I'm pursuing a different line of reasoning in this thread - with the loading of the objects. The following is their code: - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel) return managedObjectModel; NSMutableSet *allBundles = [[NSMutableSet alloc] init]; [allBundles addObject: [NSBundle mainBundle]]; [allBundles addObjectsFromArray: [NSBundle allFrameworks]]; managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL: [NSURL fileURLWithPath: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"/OsiriXDB_DataModel.mom"]]]; [allBundles release]; return managedObjectModel; } - (NSManagedObjectContext *) managedObjectContextLoadIfNecessary:(BOOL) loadIfNecessary { NSError *error = nil; NSString *localizedDescription; NSFileManager *fileManager; if( currentDatabasePath == nil) return nil; if (managedObjectContext) return managedObjectContext; if( loadIfNecessary == NO) return nil; fileManager = [NSFileManager defaultManager]; [persistentStoreCoordinator release]; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: self.managedObjectModel]; managedObjectContext = [[NSManagedObjectContext alloc] init]; [managedObjectContext setPersistentStoreCoordinator: persistentStoreCoordinator]; NSURL *url = [NSURL fileURLWithPath: currentDatabasePath]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:url options:nil error:&error]) { NSLog(@"********** managedObjectContextLoadIfNecessary FAILED: %@", error); localizedDescription = [error localizedDescription]; error = [NSError errorWithDomain:@"OsiriXDomain" code:0 userInfo:[NSDictionary dictionaryWithObjectsAndKeys:error, NSUnderlyingErrorKey, [NSString stringWithFormat:@"Store Configuration Failure: %@", ((localizedDescription != nil) ? localizedDescription : @"Unknown Error")], NSLocalizedDescriptionKey, nil]]; } [[managedObjectContext undoManager] setLevelsOfUndo: 1]; [[managedObjectContext undoManager] disableUndoRegistration]; // This line is very important, if there is NO database.sql file [self saveDatabase: currentDatabasePath]; return managedObjectContext; } This is my code: NSManagedObjectModel* DataModule::managedObjectModel() { if (_managedObjectModel) return _managedObjectModel; NSMutableSet *allBundles = [[NSMutableSet alloc] init]; [allBundles addObject: [NSBundle mainBundle]]; [allBundles addObjectsFromArray: [NSBundle allFrameworks]]; _managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL: [NSURL fileURLWithPath: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"/OsiriXDB_DataModel.mom"]]]; [allBundles release]; return [_managedObjectModel retain]; } ... NSError *error = nil; [_storeCoordinator release]; _storeCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: managedObjectModel()]; _context = [[NSManagedObjectContext alloc] init]; [_context setPersistentStoreCoordinator: _storeCoordinator]; NSURL *url = [NSURL fileURLWithPath: [[NSString alloc] initWithCString:_DBPath.c_str()]]; if (url == nil) { [pool release]; _loadLock = false; return nil; } if (![_storeCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:url options:nil error:&error]) { NSLog(@"********** managedObjectContextLoadIfNecessary FAILED: %@", error); NSString *localizedDescription = [error localizedDescription]; error = [NSError errorWithDomain:@"OsiriXDomain" code:0 userInfo:[NSDictionary dictionaryWithObjectsAndKeys:error, NSUnderlyingErrorKey, [NSString stringWithFormat:@"Store Configuration Failure: %@", ((localizedDescription != nil) ? localizedDescription : @"Unknown Error")], NSLocalizedDescriptionKey, nil]]; //Exit Failure [pool release]; _loadLock = false; return nil; } [[_context undoManager] setLevelsOfUndo: 1]; [[_context undoManager] disableUndoRegistration]; ... I am including all the same frameworks.... but _allBundles isn't even used to create the managedObjectModel so I don't know what it's supposed to do except load them into memory so that the mom can look at them while loading. Totally lost. Help! Why would objects returned by my FetchRequest with the same Entity come out as NSManagedObjects and not DicomStudys? I'm including DicomStudy.h so it should see the object during creation of the model, context, and fetch request. [request setEntity: [[managedObjectModel() entitiesByName] objectForKey:@"Study"]]; Thanks in advance, -Stephen

  • Why can't my main class see the array in my calender class

    - by Rocky Celltick Eadie
    This is a homework problem. I'm already 5 days late and can't figure out what I'm doing wrong.. this is my 1st semester in Java and my first post on this site Here is the assignment.. Create a class called Calendar. The class should contain a variable called events that is a String array. The array should be created to hold 5 elements. Use a constant value to specify the array size. Do not hard code the array size. Initialize the array in the class constructor so that each element contains the string “ – No event planned – “. The class should contain a method called CreateEvent. This method should accept a String argument that contains a one-word user event and an integer argument that represents the day of the week. Monday should be represented by the number 1 and Friday should be represented by the number 5. Populate the events array with the event info passed into the method. Although the user will input one-word events, each event string should prepend the following string to each event: event_dayAppoinment: (where event_day is the day of the week) For example, if the user enters 1 and “doctor” , the first array element should read: Monday Appointment: doctor If the user enters 2 and “PTA” , the second array element should read: Tuesday Appointment: PTA Write a driver program (in a separate class) that creates and calls your Calendar class. Then use a loop to gather user input. Ask for the day (as an integer) and then ask for the event (as a one word string). Pass the integer and string to the Calendar object’s CreateEvent method. The user should be able enter 0 – 5 events. If the user enters -1, the loop should exit and your application should print out all the events in a tabular format. Your program should not allow the user to enter invalid values for the day of the week. Any input other than 1 – 5 or -1 for the day of the week would be considered invalid. Notes: When obtaining an integer from the user, you will need to use the nextInt() method on your Scanner object. When obtaining a string from a user, you will need to use the next() method on your Scanner object. Here is my code so far.. //DRIVER CLASS /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin class driver public class driver { /** * @paramargs the command line arguments */ //begin main method public static void main(String[] args) { //initiates scanner Scanner userInput = new Scanner (System.in); //declare variables int dayOfWeek; String userEvent; //creates object for calender class calendercalenderObject = new calender(); //user prompt System.out.println("Enter day of week for your event in the following format:"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //user prompt System.out.println("Please type in the name of your event"); //collect user input userEvent = userInput.next(); //begin while loop while (dayOfWeek != -1) { //test for valid day of week if ((dayOfWeek>=1) && (dayOfWeek<=5)){ //calls createEvent method in calender class and passes 2 variables calenderObject.createEvent(userEvent,dayOfWeek); } else { //error message System.out.println("You have entered an invalid number"); //user prompts System.out.println("Press -1 to quit or enter another day"); System.out.println("Enter 1 for Monday"); System.out.println("Enter 2 for Tuesday"); System.out.println("Enter 3 for Wednsday"); System.out.println("Enter 4 for Thursday"); System.out.println("Enter 5 for Friday"); System.out.println("Enter -1 to quit"); //collect user input dayOfWeek = userInput.nextInt(); //end data validity test } //end while loop } //prints array to screen int i=0; for (i=0;i<events.length;i++){ System.out.println(events[i]); } //end main method } } /** * * @author Rocky */ //imports scanner import java.util.Scanner; //begin calender class public class calender { //creates events array String[] events = new String[5]; //begin calender class constructor public calender() { //Initializes array String[] events = {"-No event planned-","-No event planned-","-No event planned-","-No event planned-","-No event planned-"}; //end calender class constructor } //begin createEvent method public String[] createEvent (String userEvent, int dayOfWeek){ //Start switch test switch (dayOfWeek){ case 1: events[0] = ("Monday Appoinment:") + userEvent; break; case 2: events[1] = ("Tuesday Appoinment:") + userEvent; break; case 3: events[2] = ("WednsdayAppoinment:") + userEvent; break; case 4: events[3] = ("Thursday Appoinment:") + userEvent; break; case 5: events[4] = ("Friday Appoinment:") + userEvent; break; default: break; //End switch test } //returns events array return events; //end create event method } //end calender class }

  • Cascading updates with business key equality: Hibernate best practices?

    - by Traphicone
    I'm new to Hibernate, and while there are literally tons of examples to look at, there seems to be so much flexibility here that it's sometimes very hard to narrow all the options down the best way of doing things. I've been working on a project for a little while now, and despite reading through a lot of books, articles, and forums, I'm still left with a bit of a head scratcher. Any veteran advice would be very appreciated. So, I have a model involving two classes with a one-to-many relationship from parent to child. Each class has a surrogate primary key and a uniquely constrained composite business key. <class name="Container"> <id name="id" type="java.lang.Long"> <generator class="identity"/> </id> <properties name="containerBusinessKey" unique="true" update="false"> <property name="name" not-null="true"/> <property name="owner" not-null="true"/> </properties> <set name="items" inverse="true" cascade="all-delete-orphan"> <key column="container" not-null="true"/> <one-to-many class="Item"/> </set> </class> <class name="Item"> <id name="id" type="java.lang.Long"> <generator class="identity"/> </id> <properties name="itemBusinessKey" unique="true" update="false"> <property name="type" not-null="true"/> <property name="color" not-null="true"/> </properties> <many-to-one name="container" not-null="true" update="false" class="Container"/> </class> The beans behind these mappings are as boring as you can possibly imagine--nothing fancy going on. With that in mind, consider the following code: Container c = new Container("Things", "Me"); c.addItem(new Item("String", "Blue")); c.addItem(new Item("Wax", "Red")); Transaction t = session.beginTransaction(); session.saveOrUpdate(c); t.commit(); Everything works fine the first time, and both the Container and its Items are persisted. If the above code block is executed again, however, Hibernate throws a ConstraintViolationException--duplicate values for the "name" and "owner" columns. Because the new Container instance has a null identifier, Hibernate assumes it is an unsaved transient instance. This is expected but not desired. Since the persistent and transient Container objects have the same business key values, what we really want is to issue an update. It is easy enough to convince Hibernate that our new Container instance is the same as our old one. With a quick query we can get the identifier of the Container we'd like to update, and set our transient object's identifier to match. Container c = new Container("Things", "Me"); c.addItem(new Item("String", "Blue")); c.addItem(new Item("Wax", "Red")); Query query = session.createSQLQuery("SELECT id FROM Container" + "WHERE name = ? AND owner = ?"); query.setString(0, c.getName()); query.setString(1, c.getOwner()); BigInteger id = (BigInteger)query.uniqueResult(); if (id != null) { c.setId(id.longValue()); } Transaction t = session.beginTransaction(); session.saveOrUpdate(c); t.commit(); This almost satisfies Hibernate, but because the one-to-many relationship from Container to Item cascades, the same ConstraintViolationException is also thrown for the child Item objects. My question is: what is the best practice in this situation? It is highly recommended to use surrogate primary keys, and it is also recommended to use business key equality. When you put these two recommendations in to practice together, however, two of the greatest conveniences of Hibernate--saveOrUpdate and cascading operations--seem to be rendered almost completely useless. As I see it, I have only two options: Manually fetch and set the identifier for each object in the mapping. This clearly works, but for even a moderately sized schema this is a lot of extra work which it seems Hibernate could easily be doing. Write a custom interceptor to fetch and set object identifiers on each operation. This looks cleaner than the first option but is rather heavy-handed, and it seems wrong to me that you should be expected to write a plug-in which overrides Hibernate's default behavior for a mapping which follows the recommended design. Is there a better way? Am I making completely the wrong assumptions? I'm hoping that I'm just missing something. Thanks.

  • Azure Diagnostics wrt Custom Logs and honoring scheduledTransferPeriod

    - by kjsteuer
    I have implemented my own TraceListener similar to http://blogs.technet.com/b/meamcs/archive/2013/05/23/diagnostics-of-cloud-services-custom-trace-listener.aspx . One thing I noticed is that that logs show up immediately in My Azure Table Storage. I wonder if this is expected with Custom Trace Listeners or because I am in a development environment. My diagnosics.wadcfg <?xml version="1.0" encoding="utf-8"?> <DiagnosticMonitorConfiguration configurationChangePollInterval="PT1M""overallQuotaInMB="4096" xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration"> <DiagnosticInfrastructureLogs scheduledTransferLogLevelFilter="Information" /> <Directories scheduledTransferPeriod="PT1M"> <IISLogs container="wad-iis-logfiles" /> <CrashDumps container="wad-crash-dumps" /> </Directories> <Logs bufferQuotaInMB="0" scheduledTransferPeriod="PT30M" scheduledTransferLogLevelFilter="Information" /> </DiagnosticMonitorConfiguration> I have changed my approach a bit. Now I am defining in the web config of my webrole. I notice when I set autoflush to true in the webconfig, every thing works but scheduledTransferPeriod is not honored because the flush method pushes to the table storage. I would like to have scheduleTransferPeriod trigger the flush or trigger flush after a certain number of log entries like the buffer is full. Then I can also flush on server shutdown. Is there any method or event on the CustomTraceListener where I can listen to the scheduleTransferPeriod? <system.diagnostics> <!--http://msdn.microsoft.com/en-us/library/sk36c28t(v=vs.110).aspx By default autoflush is false. By default useGlobalLock is true. While we try to be threadsafe, we keep this default for now. Later if we would like to increase performance we can remove this. see http://msdn.microsoft.com/en-us/library/system.diagnostics.trace.usegloballock(v=vs.110).aspx --> <trace> <listeners> <add name="TableTraceListener" type="Pos.Services.Implementation.TableTraceListener, Pos.Services.Implementation" /> <remove name="Default" /> </listeners> </trace> </system.diagnostics> I have modified the custom trace listener to the following: namespace Pos.Services.Implementation { class TableTraceListener : TraceListener { #region Fields //connection string for azure storage readonly string _connectionString; //Custom sql storage table for logs. //TODO put in config readonly string _diagnosticsTable; [ThreadStatic] static StringBuilder _messageBuffer; readonly object _initializationSection = new object(); bool _isInitialized; CloudTableClient _tableStorage; readonly object _traceLogAccess = new object(); readonly List<LogEntry> _traceLog = new List<LogEntry>(); #endregion #region Constructors public TableTraceListener() : base("TableTraceListener") { _connectionString = RoleEnvironment.GetConfigurationSettingValue("DiagConnection"); _diagnosticsTable = RoleEnvironment.GetConfigurationSettingValue("DiagTableName"); } #endregion #region Methods /// <summary> /// Flushes the entries to the storage table /// </summary> public override void Flush() { if (!_isInitialized) { lock (_initializationSection) { if (!_isInitialized) { Initialize(); } } } var context = _tableStorage.GetTableServiceContext(); context.MergeOption = MergeOption.AppendOnly; lock (_traceLogAccess) { _traceLog.ForEach(entry => context.AddObject(_diagnosticsTable, entry)); _traceLog.Clear(); } if (context.Entities.Count > 0) { context.BeginSaveChangesWithRetries(SaveChangesOptions.None, (ar) => context.EndSaveChangesWithRetries(ar), null); } } /// <summary> /// Creates the storage table object.

  • Can't get my head around background workers in .NET

    - by Connel
    I have wrote an application that syncs two folders together. The problem with the program is that it stops responding whilst copying files. A quick search of stack-overflow told me I need to use something called a background worker. I have read a few pages on the net about this but find it really hard to understand as I'm pretty new to programming. Below is the code for my application - how can I simply put all of the File.Copy(....) commands into their own background worker (if that's even how it works)? Below is the code for the button click event that runs the sub procedure and the sub procedure I wish to use a background worker on all the File.Copy lines. Button event: protected virtual void OnBtnSyncClicked (object sender, System.EventArgs e) { //sets running boolean to true booRunning=true; //sets progress bar to 0 prgProgressBar.Fraction = 0; //resets values used by progressbar dblCurrentStatus = 0; dblFolderSize = 0; //tests if user has entered the same folder for both target and destination if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { //creates message box MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync two folders that are the same"); //sets message box title msdSame.Title="Error"; //sets respone type ResponseType response = (ResponseType) msdSame.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdSame.Destroy(); } return; } //tests if user has entered a target folder that is an extension of the destination folder // or if user has entered a desatination folder that is an extension of the target folder if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder) || fchDestination.CurrentFolder.StartsWith(fchTarget.CurrentFolder)) { //creates message box MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync a folder with one of its parent folders"); //sets message box title msdContains.Title="Error"; //sets respone type and runs message box ResponseType response = (ResponseType) msdContains.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdContains.Destroy(); } return; } //gets folder size of target folder FileSizeOfTarget(fchTarget.CurrentFolder); //gets folder size of destination folder FileSizeOfDestination(fchDestination.CurrentFolder); //runs SyncTarget procedure SyncTarget(fchTarget.CurrentFolder); //runs SyncDestination procedure SyncDestination(fchDestination.CurrentFolder); //informs user process is complete prgProgressBar.Text = "Finished"; //sets running bool to false booRunning = false; } Sync sub-procedure: protected void SyncTarget (string strCurrentDirectory) { //string array of all the directories in directory string[] staAllDirectories = Directory.GetDirectories(strCurrentDirectory); //string array of all the files in directory string[] staAllFiles = Directory.GetFiles(strCurrentDirectory); //loop over each file in directory foreach (string strFile in staAllFiles) { //string of just the file's name and not its path string strFileName = System.IO.Path.GetFileName(strFile); //string containing directory in target folder string strDirectoryInsideTarget = System.IO.Path.GetDirectoryName(strFile).Substring(fchTarget.CurrentFolder.Length); //inform user as to what file is being copied prgProgressBar.Text="Syncing " + strFile; //tests if file does not exist in destination folder if (!File.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName)) { //if file does not exist copy it to destination folder, the true below means overwrite if file already exists File.Copy (strFile, fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName, true); } //tests if file does exist in destination folder if (File.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName)) { //long (number) that contains date of last write time of target file long lngTargetFileDate = File.GetLastWriteTime(strFile).ToFileTime(); //long (number) that contains date of last write time of destination file long lngDestinationFileDate = File.GetLastWriteTime(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName).ToFileTime(); //tests if target file is newer than destination file if (lngTargetFileDate > lngDestinationFileDate) { //if it is newer then copy file from target folder to destination folder File.Copy (strFile, fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget + "/" + strFileName, true); } } //gets current file size FileInfo FileSize = new FileInfo(strFile); //sets file's filesize to dblCurrentStatus and adds it to current total of files dblCurrentStatus = dblCurrentStatus + FileSize.Length; double dblPercentage = dblCurrentStatus/dblFolderSize; prgProgressBar.Fraction = dblPercentage; } //loop over each folder in target folder foreach (string strDirectory in staAllDirectories) { //string containing directories inside target folder but not any higher directories string strDirectoryInsideTarget = strDirectory.Substring(fchTarget.CurrentFolder.Length); //tests if directory does not exist inside destination folder if (!Directory.Exists(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget)) { //it directory does not exisit create it Directory.CreateDirectory(fchDestination.CurrentFolder + "/" + strDirectoryInsideTarget); } //run sync on all files in directory SyncTarget(strDirectory); } } Any help will be greatly appreciated as after this the program will pretty much be finished :D
