• svcutil, WSDL, and the generated interfaces not being sufficient for implementation

  - by chtmd

  I have a WSDL file defining a service that I have to implement in WCF. I had read that I could generate the proxy using svcutil from the WSDL file, and that I could then use the generated interfaces to implement the service. Unfortunately, I can't quite seem to find a way to have the interfaces contain the correct attributes to expose the contracts. All operations have the "OperationContractAttribute" attribute, but it appears as though for the service to be exposed, I require the "OperationContract" for each one. Same thing with "ServiceContractAttribute" and "ServiceContract", and I imagine DataContract, but I haven't gotten that far. I could manually make these changes, but I would much prefer a technique where the existing code could be easily used, or better code could be generated for my uses. Is there some way that this can be done? Thanks. EDIT: Command used: svcutil ObjectManagerService.wsdl /n:*,Sample /o:ObjectManagerServiceProxy.cs /nologo Code sample: public interface ObjectManagerSyncPortType { // CODEGEN: Generating message contract since the operation createObject is neither RPC nor document wrapped. [System.ServiceModel.OperationContractAttribute(Action="http://www.sample.com/createObject", ReplyAction="*")] [System.ServiceModel.XmlSerializerFormatAttribute()] Sample.createObjectResponse1 createObject(Sample.createObjectRequest1 request); As best as I can tell/see the WSDL file is entirely self-contained and requires no additional XSD files.

• FileReference.load() does not as excepted

  - by Yang Bo

  I used Flash player 10, and Flex SDK 3.4. The code as followings: // Following comes callbacks function imageLoadOpenCallback(evt:Event):void { trace("in--open"); } function imageLoadCompleteCallback(evt:Event):void { trace("in--load"); var fr:FileReference = evt.target as FileReference; trace(fr.data); } function imageLoadErrorCallback(evt:IOErrorEvent):void { trace("in--ioerror"); } function imageSelectCancelCallback(evt:Event):void { trace("in cancel"); } function imageSelectCallback(evt:Event):void { trace("in -- select"); for (var i:int=0; i<frl.fileList.length; i++) { frl.fileList[i].addEventListener(Event.OPEN, imageLoadOpenCallback); frl.fileList[i].addEventListener(Event.COMPLETE, imageLoadCompleteCallback); frl.fileList[i].addEventListener(IOErrorEvent.IO_ERROR, imageLoadErrorCallback); frl.fileList[i].load(); trace(frl.fileList[i]); trace(frl.fileList[i].creationDate); trace(frl.fileList[i].creator); trace(frl.fileList[i].data); trace(frl.fileList[i].name); } } // Following comes UI handlers function onAddPictures():void { var imageFilter:FileFilter = new FileFilter("Images", "*.jpg;*.png"); frl.addEventListener(Event.SELECT, imageSelectCallback); frl.addEventListener(Event.CANCEL, imageSelectCancelCallback); frl.browse([imageFilter]); } Only the imageSelectCancelCallback handler get called when I select some files in the dialog. But no load/open/io_error handler get called at all. I have Google some code example, in which it used FileReference instead of FileReferenceList. I don't know the reason, could you please help me?

• PDCurses TUI C++ Win32 console app - Access violation reading location

  - by Bach

  I have downloaded pdcurses source and was able to successfully include curses.h in my project, linked the pre-compiled library and all good. After few hours of trying out the library, I saw the tuidemo.c in the demos folder, compiled it into an executable and brilliant! exactly what I needed for my project. Now the problem is that it's a C code, and I am working on a C++ project in VS c++ 2008. The files I need are tui.c and tui.h How can I include that C file in my C++ code? I saw few suggestions here but the compiler was not too happy with 100's of warnings and errors. How can I go on including/using that TUI pdcurses includes!? Thanks EDIT: I added extern "C" statement, so my test looks like this now, but I'm getting some other type of error #include <stdio.h> #include <stdlib.h> using namespace std; extern "C" { #include <tui.h> } void sub0(void) { //do nothing } void sub1(void) { //do nothing } int main (int argc, char * const argv[]) { menu MainMenu[] = { { "Asub", sub0, "Go inside first submenu" }, { "Bsub", sub1, "Go inside second submenu" }, { "", (FUNC)0, "" } /* always add this as the last item! */ }; startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); return 0; } Although it is compiling successfully, it is throwing an Error at runtime, which suggests a bad pointer: 0xC0000005: Access violation reading location 0x021c52f9 at line startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); Not sure where to go from here. thanks again.

• Visual Studio Macros on 64 bit fail with COM error

  - by bruce.kinchin

  I'm doing some javascript development and found a cool macro to region my code ("Using #region Directive With JavaScript Files in Visual Studio"). I used this on my 32 bit box, and it worked first time. (Visual Studio 2008 SP1, Win7) For easy of reference the macro is: Option Strict Off Option Explicit Off Imports System Imports EnvDTE Imports EnvDTE80 Imports System.Diagnostics Imports System.Collections Public Module JsMacros Sub OutlineRegions() Dim selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection Const REGION_START As String = "//#region" Const REGION_END As String = "//#endregion" DTE.ExecuteCommand("Edit.StopOutlining") selection.SelectAll() Dim text As String = selection.Text selection.StartOfDocument(True) Dim startIndex As Integer Dim endIndex As Integer Dim lastIndex As Integer = 0 Dim startRegions As Stack = New Stack() Do startIndex = text.IndexOf(REGION_START, lastIndex) endIndex = text.IndexOf(REGION_END, lastIndex) If startIndex = -1 AndAlso endIndex = -1 Then Exit Do End If If startIndex <> -1 AndAlso startIndex < endIndex Then startRegions.Push(startIndex) lastIndex = startIndex + 1 Else ' Outline region ... selection.MoveToLineAndOffset(CalcLineNumber(text, CInt(startRegions.Pop())), text.Length) selection.MoveToLineAndOffset(CalcLineNumber(text, endIndex) + 1, 1, True) selection.OutlineSection() lastIndex = endIndex + 1 End If Loop selection.StartOfDocument() End Sub Private Function CalcLineNumber(ByVal text As String, ByVal index As Integer) Dim lineNumber As Integer = 1 Dim i As Integer = 0 While i < index If text.Chars(i) = vbCr Then lineNumber += 1 i += 1 End If i += 1 End While Return lineNumber End Function End Module I then tried to use the same macro on two separate 64 bit machines (Win7 x64), identical other than the 64 bit OS version and it fails to work. Stepping through it with the Visual Studio Macros IDE, it fails the first time on the DTE.ExecuteCommand("Edit.StopOutlining") line with a COM error (Error HRESULT E_FAIL has been returned from a call to a COM component). If I attempt to run it a second time, I can run it from the Macro Editor with no issue, but not from within Visual Studio with the macro explorer 'run macro' command. I have reviewed the following articles without finding anything helpful: Stackoverflow: Visual Studio 2008 macro only works from the Macro IDE, not the Macro Explorer Recorded macro does not run; Failing on DTE.ExecuteCommand Am I missing something dumb?

• Problem connecting to Apache Derby using Hibernate configuration file in Netbeans (ERROR XSDB6)

  - by me_here

  I've created a local Apache Derby database in Netbeans, but am having problems when I try and autogenerate the POJO files, using the "Hibernate Reverse Engineering Wizard". My Hibernate configuration (generated by Netbeans from the database connection, then I added a few bits): <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Default Netbeans generated parameters --> <property name="hibernate.connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property> <property name="hibernate.connection.url">jdbc:derby:C:/CerealDatabase</property> <property name="hibernate.connection.username">cerealuser</property> <property name="hibernate.connection.password">cerealpass</property> <!-- Additional parameters --> <property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.default_schema">CEREALUSER</property> </session-factory> </hibernate-configuration> When I try and generate the POJOs using this configuration file, I get the message to check my configuration file, and the derby.log gives the errors: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details. Caused by: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details. Caused by: ERROR XSDB6: Another instance of Derby may have already booted the database C:\CerealDatabase. I've closed any other connections to the database before trying this, and there is no "db.lck" lock file at the time, which indicates there are no connections to the database as I understand it. Does anyone have any ideas? Help gratefully received.

• how to compile with llvm and g++?

  - by Sriram

  Hi, I use a fedora-11 system and recently I installed llvm ( sudo yum -y install llvm llvm-docs llvm-devel ). When I search for llvm I get them in /usr/bin. some of the links to the binaries are broken(llvm-gcc,llvm-g++,llvm-cpp,etc.) the include files are found within /usr/include/llvm and libs at /usr/lib/llvm. How to compile them using g++? I tried to compile the kaleidoscope code given in the tutorial (http://llvm.org/docs/tutorial/LangImpl3.html) as per directed, but it fails to compile.. I get this... toy.cpp:5:30: error: llvm/LLVMContext.h: No such file or directory toy.cpp:352: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In member function ‘virtual llvm::Value* NumberExprAST::Codegen()’: toy.cpp:358: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In member function ‘virtual llvm::Value* BinaryExprAST::Codegen()’: toy.cpp:379: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’ toy.cpp:379: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In member function ‘llvm::Function* PrototypeAST::Codegen()’: toy.cpp:407: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’ toy.cpp:407: error: ‘getGlobalContext’ was not declared in this scope toy.cpp:408: error: ‘getDoubleTy’ is not a member of ‘llvm::Type’ toy.cpp: In member function ‘llvm::Function* FunctionAST::Codegen()’: toy.cpp:454: error: ‘getGlobalContext’ was not declared in this scope toy.cpp: In function ‘int main()’: toy.cpp:543: error: ‘LLVMContext’ was not declared in this scope toy.cpp:543: error: ‘Context’ was not declared in this scope toy.cpp:543: error: ‘getGlobalContext’ was not declared in this scope I cannot find the LLVMContext.h file too. so i guess this might be a version problem. what should i do to make it work? some help would be good! thanks in advance... :)

• Preg Expression to identify classes/ids in a CSS file that have no contents

  - by dclowd9901

  I'm in the process of updating some old CSS files in our systems, and we have a bunch that have lots of empty classes simply taking up space in the file. I'd love to learn how to write Regular expressions, but I just don't get them. I'm hoping the more I expose myself to them (with a little more cohesive explanation), the more I'll end up understanding them. The Problem That said, I'm looking for an expression that will identify text followed by a '{' (some have spaces in between, and some do not) and if there are no letters or numbers between that bracket and '}' (spaces don't count), it will be identified as a matching string. I suppose I can trim the whitespace out of the doc before I run a regular expression through it, but I don't want to change the basic structure of the text. I'm hoping to return it into a large <textarea>. Bonus points for explaining the characters and their meanings, and also an expression identifying lines in the copy without any text or numbers, as well. I will likely use the final expression in PHP script. tl;dr: Regular Expression to match: .a_class_or #an_id { /* if there aren't any alphanumerics in here, this should be a matching line of text */ }

• scripsharp reference web service / strongly type to results model

  - by user175528

  With scriptsharp (script#) is it possible to get strong typing when calling a service defined in my web app? The only way I can see is to: 1 - use linked / shared files to shadow copy my results classes / domain models across into my script# lib 2 - replicate my model across in the script# lib and use automapper to validate? 3 - use some .tt to code gen? also, even if I can do this, how do I get around the auto camel-casing script# does, when my service result (asmx) wont do this? (so my JSON response will comback as UserMessage, script# will have changed that to userMessage) basically, what I am looking to use script# to achieve is better compile time support against our domain model when calling and processing services in javascript, so something like this: Scriptlet public static class MyScriptlet { public static void Main() { MyService.Service1("hello", ProcessResponse);} public static void ProcessResponse(MyService.Service1ResponseData resp) { jQuery.Select('#Message').Text(resp.UserMessage); jQuery.Select('#Detail').Text(resp.UserDetail); } Service (in our web app) public class MyService { public class Service1ResponseData { public string UserMessage {get;set;} public string UserDetail {get;set;} } public Service1ResponseData Service1(string user) { return new Service1ResponseData() { UserMessage:"hi",UserDetail:"some text"}; } }

• Secure hash and salt for PHP passwords

  - by luiscubal

  It is currently said that MD5 is partially unsafe. Taking this into consideration, I'd like to know which mechanism to use for password protection. Is “double hashing” a password less secure than just hashing it once? Suggests that hashing multiple times may be a good idea. How to implement password protection for individual files? Suggests using salt. I'm using PHP. I want a safe and fast password encryption system. Hashing a password a million times may be safer, but also slower. How to achieve a good balance between speed and safety? Also, I'd prefer the result to have a constant number of characters. The hashing mechanism must be available in PHP It must be safe It can use salt (in this case, are all salts equally good? Is there any way to generate good salts?) Also, should I store two fields in the database(one using MD5 and another one using SHA, for example)? Would it make it safer or unsafer? In case I wasn't clear enough, I want to know which hashing function(s) to use and how to pick a good salt in order to have a safe and fast password protection mechanism. EDIT: The website shouldn't contain anything too sensitive, but still I want it to be secure. EDIT2: Thank you all for your replies, I'm using hash("sha256",$salt.":".$password.":".$id) Questions that didn't help: What's the difference between SHA and MD5 in PHP Simple Password Encryption Secure methods of storing keys, passwords for asp.net How would you implement salted passwords in Tomcat 5.5

• is struts2 Framework dead? if so, which direction to go from here?

  - by Omnipresent

  I've been working in struts2 framework for the past year and a half. As I look around SO it seems like struts2 questions get the least amount of hits. At first I thought it was because the SO community is not much into struts2, but this is the case in other forums as well. Only the struts2 mailing list is pretty active. I think struts2 is slowly becoming a dinosaur framework and I want to move on. I've dabbled a little with other stuff like RoR, Grails, Django, .NET MVC but I've never really committed and made a pact with myself to sit down and learn these. Maybe its the fact that I dont know the languages that these frameworks are built on. Spending a day or two with RoR makes me want to choke some of the JAR files and struts2 html tags and .NET MVC looks promising but not knowing c# ties me back. My question is, have you been on the same path? Did anyone used to do struts2 before and now changed to something new? What would you suggest I learn after Struts2? And lastly, as a developer how do you motivate yourself to learn a new framework, or a language? for me, just typing the code provided in the book is dead boring.

• Request for the permission of type 'System.Data.Odbc.OdbcPermission.. help needed

  - by Matt

  I'm getting the following error when trying to connect to a remote mysql server. Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

• Unable to set variables in bash script in Mac OSX

  - by cohortq

  Hello! I am attempting to automate moving files from a folder to a new folder automatically every night using a bash script run from applescript on a schedule. I am attempting to write a bash script on Mac OSX, and it keeps failing. In short this is what I have (all my ECHOs are for error checking): !/bin/bash folder = "ABC" useracct = 'test' day = date "+%d" month = date "+%B" year = date "+%Y" folderToBeMoved = "/users/$useracct/Documents/Archive/Primetime.eyetv" newfoldername = "/Volumes/Media/Network/$folder/$month$day$year" ECHO "Network is $network" $network ECHO "day is $day" ECHO "Month is $month" ECHO "YEAR is $year" ECHO "source is $folderToBeMoved" ECHO "dest is $newfoldername" mkdir $newfoldername cp -R $folderToBeMoved $newfoldername if [-f $newfoldername/Primetime.eyetv]; then rm $folderToBeMoved; fi Now my first problem is that I cannot set variables at all. Even literal ones where I just make it equal some literal. All my echos come out blank. I cannot grab the day, month, or year either,it comes out blank as well. I get an error saying that -f is not found. I get an error saying there is an unexpected end of file. I made the file and did a chmod u+x scriptname.sh I'm not sure why nothing is working at all. I am very new to this bash script on OSX, and only have experience with windows vbscript. Any help would be great, thanks!

• Where is my Drupal View pager?

  - by anotherthink

  Hi, I have a Drupal 6 site where I've created a view that shows a list of nodes. Nothing complicated -- except that when I choose "use pager" -- "yes" (and choose the "full pager" option), the pager doesn't show up on the page. The first page of nodes shows up, but there's no way to get to other pages. Through googling, I saw that some people had an issue with the "Pager Element" item, so I changed that from 0 to 1 -- no luck. This shouldn't be very complicated, but I've been at it for a while! Help!? ETA: I've tracked it down to the following lines in /modules/views/theme/theme.inc: $pager_theme = views_theme_functions($pager_type, $view, $view->display_handler->display); $vars['pager'] = theme($pager_theme, $exposed_input, $view->pager['items_per_page'], $view->pager['element']); The first line returns an array; the second line returns nothing. I suspect now that this is a theming problem with the custom theme I'm using that may not have fully been correctly updated for Drupal 6 -- like, maybe I'm missing a pager template somehow? -- however, I'm quite new to Drupal and don't really understand how to further track down and fix the issue. Any advice would be much appreciated! ETA yet again: The pager also doesn't show up when using Garland, so it's not a theme issue after all. ALSO: I have a copy of this site set up on a development server as well, and that copy has working pagination! I've checked what I thought might be different -- files in the theme, what modules are enabled -- and it seems like pretty much everything is the same. The one thing that I know is different, however, is that the production server has a lower version of MySQL (lower than recommended for Drupal 6 -- we're waiting on the hosting company being able to change this later). Would it make sense that the old version of MySQL is unable to do pagination correctly in Drupal 6? If so, does anyone know a workaround I can do until we are able to update MySQL?

• A Linker Resolution Problem in a C++ Program

  - by Vlad

  We have two source files, a.cpp and b.cpp and a header file named constructions.h. We define a simple C++ class with the same name (class M, for instance) in each source file, respectively. The file a.cpp looks like this: #include "iostream" #include "constructions.h" class M { int i; public: M(): i( -1 ) { cout << "M() from a.cpp" << endl; } M( int a ) : i( a ) { cout << "M(int) from a.cpp, i: " << i << endl; } M( const M& b ) { i = b.i; cout << "M(M&) from a.cpp, i: " << i << endl; } M& operator = ( M& b ) { i = b.i; cout << "M::operator =(), i: " << i << endl; return *this; } virtual ~M(){ cout << "M::~M() from a.cpp" << endl; } operator int() { cout << "M::operator int() from a.cpp" << endl; return i; } }; void test1() { cout << endl << "Example 1" << endl; M b1; cout << "b1: " << b1 << endl; cout << endl << "Example 2" << endl; M b2 = 5; cout << "b2: " << b2 << endl; cout << endl << "Example 3" << endl; M b3(6); cout << "b3: " << b3 << endl; cout << endl << "Example 4" << endl; M b4 = b1; cout << "b4: " << b4 << endl; cout << endl << "Example 5" << endl; M b5; b5 = b2; cout << "b5: " << b5 << endl; } int main(int argc, char* argv[]) { test1(); test2(); cin.get(); return 0; } The file b.cpp looks like this: #include "iostream" #include "constructions.h" class M { public: M() { cout << "M() from b.cpp" << endl; } ~M() { cout << "M::~M() from b.cpp" << endl; } }; void test2() { M m; } Finally, the file constructions.h contains only the declaration of the function "test2()" (which is defined in "b.cpp"), so that it can be used in "a.cpp": using namespace std; void test2(); We compiled and linked these three files using either VS2005 or the GNU 4.1.0 compiler and the 2.16.91 ld linker under Suse. The results are surprising and different between the two build environments. But in both cases it looks like the linker gets confused about which definition of the class M it should use. If we comment out the definition of test2() from b.cpp and its invocation from a.cpp, then all the C++ objects created in test1() are of the type M defined in a.cpp and the program executes normally under Windows and Suse. Here is the run output under Windows: Example 1 M() from a.cpp M::operator int() from a.cpp b1: -1 Example 2 M(int) from a.cpp, i: 5 M::operator int() from a.cpp b2: 5 Example 3 M(int) from a.cpp, i: 6 M::operator int() from a.cpp b3: 6 Example 4 M(M&) from a.cpp, i: -1 M::operator int() from a.cpp b4: -1 Example 5 M() from a.cpp M::operator =(), i: 5 M::operator int() from a.cpp b5: 5 M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp If we enable the definition of test2() in "b.cpp" but comment out its invocation from main(), then the results are different. Under Suse, the C++ objects created in test1() are still of the type M defined in a.cpp and the program still seems to execute normally. The VS2005 versions behave differently in Debug or Release mode: in Debug mode, the program still seems to execute normally, but in Release mode, b1 and b5 are of the type M defined in b.cpp (as the constructor invocation proves), although the other member functions called (including the destructor), belong to M defined in a.cpp. Here is the run output for the executable built in Release mode: Example 1 M() from b.cpp M::operator int() from a.cpp b1: 4206872 Example 2 M(int) from a.cpp, i: 5 M::operator int() from a.cpp b2: 5 Example 3 M(int) from a.cpp, i: 6 M::operator int() from a.cpp b3: 6 Example 4 M(M&) from a.cpp, i: 4206872 M::operator int() from a.cpp b4: 4206872 Example 5 M() from b.cpp M::operator =(), i: 5 M::operator int() from a.cpp b5: 5 M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp Finally, if we allow the call to test2() from main, the program misbehaves in all circumstances (that is under Suse and under Windows in both Debug and Release modes). The Windows-Debug version finds a memory corruption around the variable m, defined in test2(). Here is the Windows output in Release mode (test2() seems to have created an instance of M defined in b.cpp): Example 1 M() from b.cpp M::operator int() from a.cpp b1: 4206872 Example 2 M(int) from a.cpp, i: 5 M::operator int() from a.cpp b2: 5 Example 3 M(int) from a.cpp, i: 6 M::operator int() from a.cpp b3: 6 Example 4 M(M&) from a.cpp, i: 4206872 M::operator int() from a.cpp b4: 4206872 Example 5 M() from b.cpp M::operator =(), i: 5 M::operator int() from a.cpp b5: 5 M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M() from b.cpp M::~M() from b.cpp And here is the Suse output. The objects created in test1() are of the type M defined in a.cpp but the object created in test2() is also of the type M defined in a.cpp, unlike the object created under Windows which is of the type M defined in b.cpp. The program crashed in the end: Example 1 M() from a.cpp M::operator int() from a.cpp b1: -1 Example 2 M(int) from a.cpp, i: 5 M::operator int() from a.cpp b2: 5 Example 3 M(int) from a.cpp, i: 6 M::operator int() from a.cpp b3: 6 Example 4 M(M&) from a.cpp, i: -1 M::operator int() from a.cpp b4: -1 Example 5 M() from a.cpp M::operator =(), i: 5 M::operator int() from a.cpp b5: 5 M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M::~M() from a.cpp M() from a.cpp M::~M() from a.cpp Segmentation fault (core dumped) I couldn't make the angle brackets appear using Markdown, so I used quotes around the header file name iostream. Otherwise, the code could be copied verbatim and tried. It is purely scholastic. The statement cin.get() at the end of main() was included just to facilitate running the program directly from VS2005 (cause it to display the output window until we could analyze the output). We are looking for a software engineer in Sunnyvale, CA and may offer that position to the programmer capable of providing an intelligent and comprehensive explanation of these anomalies. I can be contacted at [email protected].

• Which combing css technique?

  - by DotnetShadow

  Hi there, Which of the following would you say is the best way to go when combining files for CSS: Say I have a master.css file that is used across all pages on my website (page1.aspx, page2.aspx) Page1.aspx - A specific page that has some unique css that is only ever used on that page, so I create a page1.css and it also uses another css grids.css Page2.aspx - Another specific page that is different from all other pages on the site and is different to page1.aspx, I'll name this page2.aspx and make a page2.css this doesn't use grids.css So would you combine the scripts as: Option1: Combine scripts csshandler.axd?d=master.css,page1.css,grids.css when visiting page1 Combine scripts csshandler.axd?d=master.css,page2.css when visiting page2 Benefits: Page specific, rendering quicker since only selectors for that page need to be matched up no unused selectors Drawback: Multiple combinations of master.css + page specific hence master.css has to be downloaded for each page Option2: Combine all scripts whether a page needs them or not csshandler.axd?d=master.css,page1.css,page2.css,grids.css (master, page1 and page2) that way it gets cached as one. The problem is that rendering maybe slower since it will have to try and match EVERY selector in the css with selectors on the page even the missing ones, so in the case of page2.aspx that doesn't use grids.css the selectors in grids.css will need to be parsed to see if they are in page2 which means rendering will be slow Benefits: One file will ever be downloaded and cached doesn't matter what page you visit Drawback: Unused selectors will need to be parsed by the browser slower rendering Option3: Leave the master file on it's own and only combine other scripts (the benefit of this is because master is used across all pages there is a chance that this is cached so doesn't need to keep on downloading csshandler.axd?d=Master.css csshandler.axd?d=page1.css,grids.css Benefits: master.css file can be cached doesn't matter what page you visit. Not many unused selectors as page spefic is applied Drawback: Initially minimum of 2 HTTP request will have to be made What do you guys think? Cheers DotnetShadow

• Help with debugging COM errors? (.mdi to .pdf file conversions using Microsoft Office Document Imagi

  - by RyanW

  I thought I had a working solution for converting .mdi files to PDF using the Microsoft Office Document Imaging object model. The solution is in a Windows Service, but now I'm running into some errors that I'm having trouble tracking down info on. The exception I get is: The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)) System.Runtime.InteropServices.COMException (0x80010105): The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)) at MODI.DocumentClass.Create(String FileOpen) at DocumentStore.Mdi2PDF(String path, String newPath) Then, in the Event Viewer there is the following Application error: Faulting application MyWindowsServiceName.exe, version 1.0.0.0, time stamp 0x4b97f185, faulting module mso.dll, version 12.0.6425.1000, time stamp 0x49d65443, exception code 0xc0000005, fault offset 0x0000bd8e, process id 0xa5c, application start time 0x01cac08cf032914b. Here's the method that is doing the conversion: private int? Mdi2PDF(String path, String newPath) { int? pageCount = null; string tmpTif = Path.GetTempFileName(); MODI.Document mdiDoc = new MODI.Document(); mdiDoc.Create(path); mdiDoc.SaveAs(tmpTif, MODI.MiFILE_FORMAT.miFILE_FORMAT_TIFF_LOSSLESS, MODI.MiCOMP_LEVEL.miCOMP_LEVEL_HIGH); mdiDoc.Close(false); pageCount = Tiff2PDF(tmpTif, newPath); if (File.Exists(tmpTif)) File.Delete(tmpTif); return pageCount; } I removed all threading from the service invoking this, so that only the primary thread was initializing the MODI object, but still got the error, so it doesn't appear to be threading related. I also built a a console apps converting hundreds of documents and DID NOT get the exception. So, it seems to be caused by creating too many instances of the MODI object, but only instantiated within a Service? Doesn't quite make sense. Anybody have any clues about these errors and how to debug them further?

• What is the best way to send structs containing enum values via sockets in C.

  - by Axel

  I've lots of different structs containing enum members that I have to transmit via TCP/IP. While the communication endpoints are on different operating systems (Windows XP and Linux) meaning different compilers (gcc 4.x.x and MSVC 2008) both program parts share the same header files with type declarations. For performance reasons, the structures should be transmitted directly (see code sample below) without expensively serializing or streaming the members inside. So the question is how to ensure that both compilers use the same internal memory representation for the enumeration members (i.e. both use 32-bit unsigned integers). Or if there is a better way to solve this problem... //type and enum declaration typedef enum { A = 1, B = 2, C = 3 } eParameter; typedef enum { READY = 400, RUNNING = 401, BLOCKED = 402 FINISHED = 403 } eState; #pragma pack(push,1) typedef struct { eParameter mParameter; eState mState; int32_t miSomeValue; uint8_t miAnotherValue; ... } tStateMessage; #pragma pack(pop) //... send via socket tStateMessage msg; send(iSocketFD,(void*)(&msg),sizeof(tStateMessage)); //... receive message on the other side tStateMessage msg_received; recv(iSocketFD,(void*)(&msg_received),sizeof(tStateMessage)); Additionally... Since both endpoints are little endian maschines, endianess is not a problem here. And the pack #pragma solves alignment issues satisfactorily. Thx for your answers, Axel

• How to print PDF on default network printer using GhostScript (gswin32c.exe) shell command

  I'd like to print PDF file(s) on windows' network printer via GhostScript. (I dont want to use Adobe Reader) I've read gswin32c.exe which can do the job.

• I want to merge two PostScript Documents, pagewise. How?

  - by Peter Miehle

  hello, i have a tricky question, so i need to describe my problem: i need to print 2-sided booklets (a third of a paper) on normal paper (german A4, but letter is okay also) and cut the paper afterwards. The Pages are in a Postscript Level 2 File (generated by an ancient printer driver, so no chance to patch that, except ps2ps) generated by me with the ancient OS's Printing driver facilities (GpiMove, GpiLine, GpiText etc). I do not want to throw away two-thirds of the paper, so my idea is: Take file one, two and three, merge them (how?) on new double-sided papers by translate/move file two and three by one resp. two thirds and print the resulting new pages. If it helps, I can manage to print one page of the booklet per file. I cannot "speak" postscript natively, but I am capable of parsing and merging and manipulating files programmaticly. Maybe you can hint me to a webpage. I've read through the manuals on adobe's site and followed the links on www.inkguides.com/postscript.asp Maybe there are techniques with PDF that would help? I can translate ps2pdf. Thanks for help Peter Miehle PS: my current solution: i.e. 8 pages: print page 1, 4 and 7 on page one, 2,5,8 on page two and 3,6,blank on page three, cut the paper and restack. But i want to use a electrical cutting machine, which works better with thicker stacks of paper.

• How to set "Run this program as an administrator" programatically.

  - by Patrick

  I'm having a problem with good ol' bdeadmin.exe in Vista. First, let's get the predictable responses out of the way: "You should not require your application to be elevated." This one does. C'est la vie. "You need to embed a manifest file." It is already compiled, it is many years old, the company that created it has no intention of doing it again, and it is installed from a Merge Module (MSM file). "BDE is obsolete, you should be using dbExpress" One and a half million lines of code. 'Nuff said. "Drop a manifest file next to the EXE." Tried that, did nothing. As a test, that same manifest file was able to make several other EXE files require elevation, just not the one I wanted. Something in there is preventing the external manifest from being read. "Create a shortcut and set SLDF_RUNAS_USER." Can't do that, it's a Control Panel applet. The only thing that worked was setting "Run this program as an administrator" under the Compatibility tab of its Properties window. I shouldn't have to tell users to do this. Bad for business. I need to have the installer do this. The MSM file uses a static path. Any ideas?

• PHP Site Deployment Suggestion

  - by TheOnly92

  I'm currently quite troubled by the way of deployment my team is adopting... It's very old-fashioned and I know it doesn't work very well. But I don't exactly know how to change it, so please give some suggestions about it... Here is our current setup: 2 webservers 1 database server 1 test server Current deployment adaptation 1. We develop and work on the test server, every changes is uploaded manually to the test server. 2. When a change or feature is complete, we then commit the changes to SVN repository. 3. After committing the changes, we then upload our changes to the first webserver, where there will be a cronjob running every minute to sync the files between the servers. Something very annoying is, whenever we upload a file just as the syncing job starts, the file that is sync-ed will appear corrupted, since it is only half-uploaded. Another thing is whenever there is a deployment fault, it will be extremely difficult to revert. These are basically the problem I'm facing, what should I do?

• How to make sure Solr/Lucene won't die with java.lang.OutOfMemoryError?

  - by taw

  I'm really puzzled why it keeps dying with java.lang.OutOfMemoryError during indexing even though it has a few GBs of memory. Is there a fundamental reason why it needs manual tweaking of config files / jvm parameters instead of it just figuring out how much memory is available and limiting itself to that? No other programs except Solr ever have this kind of problem. Yes, I can keep tweaking JVM heap size every time such crashes happen, but this is all so backwards. Here's stack trace of the latest such crash in case it is relevant: SEVERE: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOfRange(Arrays.java:3209) at java.lang.String.<init>(String.java:216) at org.apache.lucene.index.TermBuffer.toTerm(TermBuffer.java:122) at org.apache.lucene.index.SegmentTermEnum.term(SegmentTermEnum.java:169) at org.apache.lucene.search.FieldCacheImpl$StringIndexCache.createValue(FieldCacheImpl.java:701) at org.apache.lucene.search.FieldCacheImpl$Cache.get(FieldCacheImpl.java:208) at org.apache.lucene.search.FieldCacheImpl.getStringIndex(FieldCacheImpl.java:676) at org.apache.lucene.search.FieldComparator$StringOrdValComparator.setNextReader(FieldComparator.java:667) at org.apache.lucene.search.TopFieldCollector$OneComparatorNonScoringCollector.setNextReader(TopFieldCollector.java:94) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:245) at org.apache.lucene.search.Searcher.search(Searcher.java:171) at org.apache.solr.search.SolrIndexSearcher.getDocListNC(SolrIndexSearcher.java:988) at org.apache.solr.search.SolrIndexSearcher.getDocListC(SolrIndexSearcher.java:884) at org.apache.solr.search.SolrIndexSearcher.search(SolrIndexSearcher.java:341) at org.apache.solr.handler.component.QueryComponent.process(QueryComponent.java:182) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:195) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1316) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:338) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:241) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619)
