  • problem finding a header with a c++ makefile

    - by Max
    Hi. I've started working with my first makefile. I'm writing a roguelike in C++ using the libtcod library, and have the following hello world program to test if my environment's up and running: #include "libtcod.hpp" int main() { TCODConsole::initRoot(80, 50, "PartyHack"); TCODConsole::root->printCenter(40, 25, TCOD_BKGND_NONE, "Hello World"); TCODConsole::flush(); TCODConsole::waitForKeypress(true); } My project directory structure looks like this: /CppPartyHack ----/libtcod-1.5.1 # this is the libtcod root folder --------/include ------------libtcod.hpp ----/PartyHack --------makefile --------partyhack.cpp # the above code (while we're here, how do I do proper indentation? Using those dashes is silly.) and here's my makefile: SRCDIR = . INCDIR = ../libtcod-1.5.1/include CFLAGS = $(FLAGS) -I$(INCDIR) -I$(SRCDIR) -Wall CC = gcc CPP = g++ .SUFFIXES: .o .h .c .hpp .cpp $(TEMP)/%.o : $(SRCDIR)/%.cpp $(CPP) $(CFLAGS) -o $@ -c $< $(TEMP)/%.o : $(SRCDIR)/%.c $(CC) $(CFLAGS) -o $@ -c $< CPP_OBJS = $(TEMP)partyhack.o all : partyhack partyhack : $(CPP_OBJS) $(CPP) $(CPP_OBJS) -o $@ -L../libtcod-1.5.1 -ltcod -ltcod++ -Wl,-rpath,. clean : \rm -f $(CPP_OBJS) partyhack I'm using Ubuntu, and my terminal gives me the following errors: max@max-desktop:~/Desktop/Development/CppPartyhack/PartyHack$ make g++ -c -o partyhack.o partyhack.cpp partyhack.cpp:1:23: error: libtcod.hpp: No such file or directory partyhack.cpp: In function ‘int main()’: partyhack.cpp:5: error: ‘TCODConsole’ has not been declared partyhack.cpp:6: error: ‘TCODConsole’ has not been declared partyhack.cpp:6: error: ‘TCOD_BKGND_NONE’ was not declared in this scope partyhack.cpp:7: error: ‘TCODConsole’ has not been declared partyhack.cpp:8: error: ‘TCODConsole’ has not been declared make: * [partyhack.o] Error 1 So obviously, the makefile can't find libtcod.hpp. I've double checked and I'm sure the relative path to libtcod.hpp in INCDIR is correct, but as I'm just starting out with makefiles, I'm uncertain what else could be wrong. My makefile is based off a template that the libtcod designers provided along with the library itself, and while I've looked at a few online makefile tutorials, the code in this makefile is a good bit more complicated than any of the examples the tutorials showed, so I'm assuming I screwed up something basic in the conversion. Thanks for any help.

  • C# ...extract email address from inside 100's of text files

    - by Developer
    My SMTP server got 100's of errors when sending lots of emails. Now have lots of .BAD files each one containing an error message and somewhere in the middle, the actual email address it was supposed to be sent to. What is the easiest way to extract from each file "just" the "email address", so that I can have a list of the actual failed emails? I can code in C# and any suggestion will be truly welcomed.

  • Glassfish: Storing Java classes in the docroot folder?

    - by Tom Marthenal
    I'm very new to using Glassfish or JSP. I have this working in NetBeans (which has Glassfish bundled) but when I try to put it on my server which is running Glassfish Server, I really don't know what I'm doing. I can place a JSP file in "domains/domain1/docroot/index.jsp" and it will work when I visit my site, but I can't, for some reason, get Java classes to work. I copied the files in "/build/web/" from the NetBeans project to the docroot folder on my server. The errors I get when I visit the site are: org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP PWC6199: Generated servlet error: string:///index_jsp.java:7: package test does not exist PWC6197: An error occurred at line: 5 in the jsp file: /index.jsp PWC6199: Generated servlet error: string:///index_jsp.java:52: cannot find symbol symbol : class TestClass location: class org.apache.jsp.index_jsp PWC6197: An error occurred at line: 5 in the jsp file: /index.jsp PWC6199: Generated servlet error: string:///index_jsp.java:52: cannot find symbol symbol : class TestClass location: class org.apache.jsp.index_jsp The actual Java class is in "WEB-INF/classes/test/TestClass.class" (it is pre-compiled). I really have no idea what I'm doing wrong so any help is greatly appreciated. Thanks!

  • jQuery Validation plugin: disable validation for specified submit buttons when there is submitHandle

    - by ccppjava
    Ok, I am using umbraco forum module, and on the comment form it uses jquery validate plugin. The problem is that I have added a search button on the same page using a UserControl, the search submit button triggers the comment form submission validation. I have done some research, and added the 'cancel' css class to the button. This bypass the first validation issue, however, it still fall into the 'submitHandler'. Have read the source code and find a way to detect whether the search button triggers the submission. however, there is not a nice way to bypass the handler. I am currently using a ugly way to do it: create javascript errors! I would like to know a nicer way to do the job. Many thanks! Btw, I am currently using: submitHandler: function (form) { $(form).find(':hidden').each(function () { var name = $(this).attr('name'); if (name && name.indexOf('btnSearch') === name.length - 'btnSearch'.length) { // this is a dirty hack to avoid the validate plugin to work for the button eval("var error = 1 2 ''"); } }); // original code from umbraco ignored here.... } ...............

  • Good Replacement for User Control?

    - by David Lively
    I found user controls to be incredibly useful when working with ASP.NET webforms. By encapsulating the code required for displaying a control with the markup, creation of reusable components was very straightforward and very, very useful. While MVC provides convenient separation of concerns, this seems to break encapsulation (ie, you can add a control without adding or using its supporting code, leading to runtime errors). Having to modify a controller every time I add a control to a view seems to me to integrate concerns, not separate them. I'd rather break the purist MVC ideology than give up the benefits of reusable, packaged controls. I need to be able to include components similar to webforms user controls throughout a site, but not for the entire site, and not at a level that belongs in a master page. These components should have their own code not just markup (to interact with the business layer), and it would be great if the page controller didn't need to know about the control. Since MVC user controls don't have codebehind, I can't see a good way to do this. I've searched previous SO questions, and have yet to find a good answer. Options so far In an attempt to avoid turning the comments section into a discussion... RenderAction This allows the view to call another controller, which will be responsible for interacting with the BLL and whatever data is necessary to its corresponding view. The calling view needs to be aware of the sub controller. This seems to provide a nice way to encapsulate partial views and controls, without having to modify the calling controller. RenderPartial The calling controller is still responsible for executing whatever code is associated with the partial view, and making sure that the model passed to the partial view contains the data it expects. Effectively, modifying the partial view potentially means modifying the calling controller. Annoying especially if this is used in multiple places. Portable Areas Place each control in its own project/area?

  • jQuery class selectors with nested div's

    - by mboles57
    This is part of some HTML from which I need to retrieve a piece of data. The HTML is assigned to a variable called fullDescription. <p>testing</p> <div class="field field-type-text field-field-video-short-desc"> <div class="field-label">Short Description:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> Demonstrates the basics of using the Content section of App Cloud Studio </div> </div> </div> <div class="field field-type-text field-field-video-id"> <div class="field-label">Video ID:&nbsp;</div> <div class="field-items"> <div class="field-item odd"> 1251462871001 </div> </div> </div> I wish to retrieve the video ID number (1251462871001). I was thinking something like this: var videoID = $(fullDescription).find(".field.field-type-text.field-field-video-id").find(".field-item.odd").html(); Although it does not generate any syntax errors, it does not retrieve the number. Thanks for helping out a jQuery noob! -Matt

  • Windows Forms application C# | Sending Tweet

    - by Andrew Craswell
    I've been able to get my Twitter web app working just fine, but I've recently decided to add Tweeting functionality from a Windows Form, but I'm having no luck sending tweets. No errors are thrown or anything. Mind looking over my code? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using TweetSharp; namespace TwitterAdvirtiser { public partial class Form1 : Form { private string cKey = "xxx"; private string cSecret = "xxx"; private string oToken = "xxx"; private string aToken = "xxx"; public Form1() { InitializeComponent(); OnStart(); } private void OnStart() { //Authenticate with Twitter TwitterService service = new TwitterService(cKey, cSecret); service.AuthenticateWith(oToken, aToken); service.SendTweet("testing"); } } } It seems like I'm authenticating just fine, I can walk through debug mode and see all my details in the TwitterUser structure, and yet my tweets never show up on my feed. Whats up? By the way, I'm using Visual Studios 2010, and .NET 4.0. I have verified that the oToken and aToken strings have my developer tokens.

  • Android: Defined array resource not found ?!

    - by David
    Hi, i have a strange (?) error in my android application. I have defined some arrays in values/arrays.xml the following way: <?xml version="1.0" encoding="utf-8"?> <resources> <array name="perimeter"> <item>10 miles</item> <item>20 miles</item> <item>30 miles</item> </array> <array name="regvalues"> <item>1</item> <item>2</item> <item>3</item> </array> </resources> Now I want to use them in a ListPreference for a PreferenceActivity (defined by an xml file). So i set android:entries="@array/perimeter" android:entryValues="@array/regvalues" for this ListPreference. When I try to use this on my device the app crashes. (NullPointer in Dialog.close()) If I try to use the regvalues-items as Entries for the ListPreference i get a NullPointer in ArrayAdapter.createViewFromResource(int, View, ViewGroup, int) line: 355 So there seems to be sth wrong with the regvalues array. But what ?!? Eclipse shows me no errors at compile time. So everything in the xml-file and java-code is written correctly and there are no typos. Where is the problem?!?

  • How to get at JSON in grails 2.0

    - by Mikey
    I am sending myself JSON like so with jQuery: $.ajax ({ type: "POST", url: 'http://localhost:8080/myproject/myController/myAction', dataType: 'json', async: false, //json object to sent to the authentication url data: {"stuff":"yes", "listThing":[1,2,3], "listObjects":[{"one":"thing"},{"two":"thing2"}]}, success: function () { alert("Thanks!"); } }) I send this to a controller and do println params And I know I'm already in trouble... [stuff:yes, listObjects[1][two]:thing2, listObjects[0][one]:thing, listThing[]:[1, 2, 3], action:myAction, controller:myController] I cannot figure out how to get at most of these values... I can get "yes" with params.stuff, but I cant do params.listThing.each{} or params.listObjects.each{} What am I doing wrong? UPDATE: I make the controller do this to try the two suggestions so far: println params println params.stuff println params.list('listObjects') println params.listThing def thisWontWork = JSON.parse(params.listThing) render("omg l2json") look how weird the parameters look at the end of the null pointer exception when I try the answers: [stuff:yes, listObjects[1][two]:thing2, listObjects[0][one]:thing, listThing[]:[1, 2, 3], action:l2json, controller:rateAPI] yes [] null | Error 2012-03-25 22:16:13,950 ["http-bio-8080"-exec-7] ERROR errors.GrailsExceptionResolver - NullPointerException occurred when processing request: [POST] /myproject/myController/myAction - parameters: stuff: yes listObjects[1][two]: thing2 listObjects[0][one]: thing listThing[]: 1 listThing[]: 2 listThing[]: 3 UPDATE 2 I am learning things, but this can't be right: println params['listThing[]'] println params['listObjects[0][one]'] prints [1, 2, 3] thing It seems like this is some part of grails new JSON marshaling. This is somewhat inconvenient for my purposes of hacking around with the values. How would I get all these individual params back into a big groovy object of nested maps and lists? Maybe I am not doing what I want with jQuery?

  • Altering ManagedObjects In NSArray

    - by Garry
    I have an entity called 'Job' with two boolean attributes named 'completed' and 'logged'. I am trying to retrieve all completed jobs that have not been logged at app start-up and change them to logged. I'm able to get all the completed but unlogged jobs with this fetchRequest: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(completed == %@ && logged == %@)", [NSNumber numberWithBool:YES], [NSNumber numberWithBool:NO]]; I'm then assigning this predicate to a fetchRequest and calling the [managedObjectContext executeFetchRequest:fetchRequest] method to get an array of all Job entities that meet this criteria. This seems to work fine and is returning the correct number of jobs. What I've been trying to do is loop through the NSArray returned, set the logged attribute to YES and then save. This seems to complete and doesn't return any errors but the changes are not persisted when the application quits. Where am I going wrong? [fetchRequest setPredicate:predicate]; NSError error; NSArray jobsToLog = [managedObjectContext executeFetchRequest:fetchRequest error:&error]; if ([jobsToLog count] > 0) { for (int i = 0; i < [jobsToLog count] - 1; i++) { [[jobsToLog objectAtIndex:i] setLogged:[NSNumber numberWithBool:YES]]; // Commit the changes made to disk error = nil; if (![managedObjectContext save:&error]) { // An error occurred } } } Thanks in anticipation,

  • Using entity framework to connect to multiple similar tables in .net MVC.

    - by Dite
    A relative newcomer to .net MVC2 and the entity framework, I am working on a project which requires a single web application, (C# .net 4), to connect to multiple different databases depending on the route of access, (ie subdomain). No problem with this in principle and all the logic is written to transform the subdomain into an entity connection and pass this through to the Entity Model. The problem comes with the fact that the different database whilst being largely similar in structure contain 3 or 4 unique tables bespoke to that instance. To my mind there are two ways to solve this issue, neither of which i am sure will be possible. 1/ Use a separate entity model for each database. -Attempts down this route have through up conflicts where table/sp names are the same across differnt db's, or implicit conversion errors when I try and put the different models in different namespaces. or 2/ Overwrite the classes which refer to the changeable database objects based on the value of a base controller property. -I have found nothing to suggest i can even do this. My question is if either of theser routes can ever work in principle or if i should just give up on the EF and connect to the dtabases directlky using ADO. Perhaps there is another way to solve this problem i haven't thought of? Thanks for any help...

  • MySQL developer here -- Nesting with select * finicky in Oracle 10g?

    - by John Sullivan
    I'm writing a simple diagnostic query then attempting to execute it in the Oracle 10g SQL Scratchpad. EDIT: It will not be used in code. I'm nesting a simple "Select *" and it's giving me errors. In the SQL Scratchpad for Oracle 10g Enterprise Manager Console, this statement runs fine. SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ' If I try to wrap that up in Select * from () tb2 I get an error, "ORA-00918: Column Ambiguously Defined". I didn't think that could ever happen with this kind of statement so I am a bit confused. select * from (SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ') tb2 You should always be able to select * from the result set of another select * statement using this structure as far as I'm aware... right? Is Oracle/10g/the scratchpad trying to force me to accept a certain syntactic structure to prevent excessive nesting? Is this a bug in scratchpad or something about how oracle works?

  • Disabling repeating keyboard down event in as3

    now I'm trying to make the keyboard events to stop repeating. My idea was to have a true and false condition for when the key is pressed so that it wont repeat if the key is down already. //Mouse Event Over keyCButton.addEventListener(MouseEvent.MOUSE_OVER, function(){gotoAndStop(2)}); //Variable var Qkey:uint = 81; //Key Down Event stage.addEventListener(KeyboardEvent.KEY_DOWN, keydown); var soundplayed = false; function keydown(event:KeyboardEvent){ if (event.keyCode==Qkey) { this.soundplayed=true;} } if (this.soundplayed==false){ gotoAndPlay(3); } else {} //Key Up Event stage.addEventListener(KeyboardEvent.KEY_UP, keyup); function keyup(event:KeyboardEvent){ if (event.keyCode==Qkey) { this.soundplayed=true; gotoAndStop(1); } } doing this just turns off the key event I think i need to add a "&& keyDown..." to "if (this.soundplayed==true)" but i dont know how to do it without getting errors here is the keyboard player i'm trying to fix http://soulseekrecords.org/psysci/animation/piano.html

  • Glassfish 3: How do I get and use a developers build so I can navigate a stack trace including Glas

    - by Thorbjørn Ravn Andersen
    I am migrating a JSF 1.1 application to JEE 6 Web profile, and doing it in steps. I am in the process of moving from JSP with JSF 1.1 to Facelets under JSF 1.2 using the jsf-facelets.jar for JSF 1.2, and received an "interesting" stack trace when trying to lookup a key in a Map using a "{Bean.foo.map.key}" where the stacktrace complained about "key" not being a valid integer. (After code introspection I am workarounding it using a number as the key). That bug is not what this question is about. In such a situation it is essential to be able to navigate the source of every line in the stack trace. In Eclipse I normally attach a source jar to every jar on the build path, but in this particular case the Glassfish server adapter creates a library automatically containing the jars. Also there is to my knowledge no debug build of Glassfish where sources are included in the bundle. Glassfish is a non-trivial Maven project, and a bit picky too. I am not very familiar with maven, but have managed to checkout the code from Subversion and build it for the 3.0 tag according to http://wiki.glassfish.java.net/Wiki.jsp?page=V3FullBuildInstructions#section-V3FullBuildInstructions-CheckoutTheWorkspace - it appears to be the code corresponding to the official released 3.0 version. After finishing the "mvn -U install" part, I have then tried to create Eclipse projects by first using "mvn -DdownloadSources=true eclipse:eclipse" and then import them in Eclipse JEE 3.5.2 and specifying the M2_REPO variable but many of the projects still have compilation errors, and I cannot locate any instructions from Oracle about how to do this. I'd appreciate some help in just getting a functional IDE workspace reflecting the 3.0 version of Glassfish. I have Eclipse 3.5.2, Netbeans 6.8 and 6.9 beta, and IntelliJ IDEA 9, and Linux/Windows/OS X do do it on.

  • Howcome some C++ functions with unspecified linkage build with C linkage?

    - by christoffer
    This is something that makes me fairly perplexed. I have a C++ file that implements a set of functions, and a header file that defines prototypes for them. When building with Visual Studio or MingW-gcc, I get linking errors on two of the functions, and adding an 'extern "C"' qualifier resolved the error. How is this possible? Header file, "some_header.h": // Definition of struct DEMO_GLOBAL_DATA omitted DWORD WINAPI ThreadFunction(LPVOID lpData); void WriteLogString(void *pUserData, const char *pString, unsigned long nStringLen); void CheckValid(DEMO_GLOBAL_DATA *pData); int HandleStart(DEMO_GLOBAL_DATA * pDAta, TCHAR * pLogFileName); void HandleEnd(DEMO_GLOBAL_DATA *pData); C++ file, "some_implementation.cpp" #include "some_header.h" DWORD WINAPI ThreadFunction(LPVOID lpData) { /* omitted */ } void WriteLogString(void *pUserData, const char *pString, unsigned long nStringLen) { /* omitted */ } void CheckValid(DEMO_GLOBAL_DATA *pData) { /* omitted */ } int HandleStart(DEMO_GLOBAL_DATA * pDAta, TCHAR * pLogFileName) { /* omitted */ } void HandleEnd(DEMO_GLOBAL_DATA *pData) { /* omitted */ } The implementations compile without warnings, but when linking with the UI code that calls these, I get a normal error LNK2001: unresolved external symbol "int __cdecl HandleStart(struct _DEMO_GLOBAL_DATA *, wchar_t *) error LNK2001: unresolved external symbol "void __cdecl CheckValid(struct _DEMO_MAIN_GLOBAL_DATA * What really confuses me, now, is that only these two functions (HandleStart and CheckValid) seems to be built with C linkage. Explicitly adding "extern 'C'" declarations for only these two resolved the linking error, and the application builds and runs. Adding "extern 'C'" on some other function, such as HandleEnd, introduces a new linking error, so that one is obviously compiled correctly. The implementation file is never modified in any of this, only the prototypes.

Here is the code snippet: NSDictionary *myDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"First letter of the alphabet", @"A", @"Second letter of the alphabet", @"B", @"Third letter of the alphabet", @"C", nil ]; I can see the dictionary contents displayed properly with either method calls: NSLog(@"Here is my partial dictionary %@", myDictionary); for (NSString *key in myDictionary) NSLog(@"here it is again %@ %@", key, [myDictionary objectForKey:key]); The following code displays the "succeeded" message when the program is run repeatedly if ([myDictionary writeToFile: @"myDictionary" atomically:YES ] == NO) NSLog(@"write to file failed"); else NSLog(@"write to file succeeded"); even when changing the atomically: argument to NO to not write a temporary file. However, when I search my current directory, or even my entire Mac, I cannot find any file called "myDictionary.plist" or any file with the string "myDictionary". Isn't the path variable "@myDictionary" supposed to represent the file at the current directory, i.e. where the class executable resides?

  • An Erroneous SQL Query makes browser hang until script timeout exceeded

    - by Jimbo
    I have an admin page in a Classic ASP web application that allows the admin user to run queries against the database (SQL Server 2000) Whats really strange is that if the query you send has an error in it (an invalid table join, a column you've forgotten to group by etc) the BROWSER hangs (CPU usage goes to maximum) until the SERVER script timeout is exceeded and then spits out a timeout exceeded error (server and browser are on different machines, so not sure how this happens!) I have tried this in IE 8 and FF 3 with the same result. If you run that same query (with errors) directly from SQL Enterprise Manager, it returns the real error immediately. Is this a security feature? Does anyone know how to turn it off? It even happens when the connection to the database is using 'sa' credentials so I dont think its a security setting :( Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If

  • creating new instance fails PHP

    - by as3isolib
    I am relatively new to PHP and having some decent success however I am running into this issue: If I try to create a new instance of the class GenericEntryVO, I get a 500 error with little to no helpful error information. However, if I use a generic object as the result, I get no errors. I'd like to be able to cast this object as a GenericEntryVO as I am using AMFPHP to communicate serialize data with a Flex client. I've read a few different ways to create constructors in PHP but the typical 'public function Foo()' for a class Foo was recommended for PHP 5.4.4 //in my EntryService.php class public function getEntryByID($id) { $link = mysqli_connect("localhost", "root", "root", "BabyTrackingAppDB"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT * FROM Entries WHERE id = '$id' LIMIT 1"; if ($result = mysqli_query($link, $query)) { // $entry = new GenericEntryVO(); this is where the problem lies! while ($row = mysqli_fetch_row($result)) { $entry->id = $row[0]; $entry->entryType = $row[1]; $entry->title = $row[2]; $entry->description = $row[3]; $entry->value = $row[4]; $entry->created = $row[5]; $entry->updated = $row[6]; } } mysqli_free_result($result); mysqli_close($link); return $entry; } //my GenericEntryVO.php class <?php class GenericEntryVO { public function __construct() { } public $id; public $title; public $entryType; public $description; public $value; public $created; public $updated; // public $properties; } ?>

  • flex 4 release changes to application are not showing up.

    - by guacamoly
    I just took over a clients flex project and I can't get the app to reflect even a simple trace statement. Before I took over, the project was last successfully built using the Flash Builder Beta 2 environment/sdk. I have the latest release version of Flash Builder 4. Upon importing the project into FB4, I got a ton of errors. Most of them mostly because of the changes made to the sdk from beta2 to release. Some of the things I corrected: - mx namespace from library://ns.adobe.com/flex/halo to library://ns.adobe.com/flex/mx - video player skinning: a lot of the state names for the video player component had been changed, more required states had been added. also there were other video related component and property names that had to be updated. But I fixed all that and the application was finally able to compile (although with some warnings mostly of the duplicate variable type) The only thing now is that whatever change I make to the project doesn't get reflected in the build (debug or release). I changed existing traces, added additional traces. Nothing shows up. I even removed the applicationComplete property in the main.mxml. Everything still ran like nothing changed. Also I can't seem to debug the app. Whenever I try to debug.. flash builder says.. "Swf Application doesn't contain the required debugging information ... " Anyone have any idea how I need to even begin tackling all this? Any help or pointers would be greatly appreciated.

  • Using array of Action() in a lambda expression

    - by Sean87
    I want to do some performance measurement for a method that does some work with int arrays, so I wrote the following class: public class TimeKeeper { public TimeSpan Measure(Action[] actions) { var watch = new Stopwatch(); watch.Start(); foreach (var action in actions) { action(); } return watch.Elapsed; } } But I can not call the Measure mehotd for the example below: var elpased = new TimeKeeper(); elpased.Measure( () => new Action[] { FillArray(ref a, "a", 10000), FillArray(ref a, "a", 10000), FillArray(ref a, "a", 10000) }); I get the following errors: Cannot convert lambda expression to type 'System.Action[]' because it is not a delegate type Cannot implicitly convert type 'void' to 'System.Action' Cannot implicitly convert type 'void' to 'System.Action' Cannot implicitly convert type 'void' to 'System.Action' Here is the method that works with arrays: private void FillArray(ref int[] array, string name, int count) { array = new int[count]; for (int i = 0; i < array.Length; i++) { array[i] = i; } Console.WriteLine("Array {0} is now filled up with {1} values", name, count); } What I am doing wrong?

  • How do I trace SQL Server Failure Audit events?

    - by Tim Perry
    I recently took over management of a Windows 2003 server. The application log is being filled up with messages like these: Event Type: Failure Audit Event Source: MSSQLSERVER Event Category: (4) Event ID: 18456 Date: 3/5/2010 Time: 4:00:30 PM User: N/A Computer: FAIROAKS1 Description: Login failed for user 'administrator'.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. I'd like to figure out what program is causing these. Is there a way to trace and find out which process is causing these errors?

  • Findbugs and comparing

    - by Rob Goodwin
    I recently started using the findbugs static analysis tool in a java build I was doing. The first report came back with loads of High Priority warnings. Being the obsessive type of person, I was ready to go knock them all out. However, I must be missing something. I get most of the warnings when comparing things. Such as the following code: public void setSpacesPerLevel(int value) { if( value >= 0) { ... produces a high priority warning at the if statement that reads. File: Indenter.java, Line: 60, Type: BIT_AND_ZZ, Priority: High, Category: CORRECTNESS Check to see if ((...) & 0) == 0 in sample.Indenter.setSpacesPerLevel(int) I am comparing an int to an int, seems like a common thing. I get quite a few of that type of error with similar simple comparisons. I have alot of other high priority warnings on what appears to be simple code blocks. Am I missing something here? I realize that static analysis can produce false positives, but the errors I am seeing seem too trivial of a case to be a false positive. This one has me scratching my head as well. for(int spaces = 0;spaces < spacesPerLevel;spaces++){... Which gives the following findbugs warning: File: Indenter.java, Line: 160, Type: IL_INFINITE_LOOP, Priority: High, Category: CORRECTNESS There is an apparent infinite loop in sample.Indenter.indent() This loop doesn't seem to have a way to terminate (other than by perhaps throwing an exception). Any ideas? So basically I have a handful of files and 50-60 high priority warnings similar to the ones above. I am using findbugs 1.3.9 and calling it from the findbugs ant task
