• Will this cause a problem with different runtimes with DLL?

  - by Milo

  My gui application supports polymorphic timed events so that means that the user calls new, and the gui calls delete. This can create a problem if the runtimes are incompatible. So I was told a proposed solution would be this: class base; class Deallocator { void operator()(base* ptr) { delete ptr; } } class base { public: base(Deallocator dealloc) { m_deleteFunc = dealloc; } ~base() { m_deleteFunc(this); } private: Deallocator m_deleteFunc; } int main { Deallocator deletefunc; base baseObj(deletefunc); } While this is a good solution, it does demand that the user create a Deallocator object which I do not want. I was however wondering if I provided a Deallocator to each derived class: eg class derived : public base { Deallocator dealloc; public: Derived() : base(dealloc); { } }; I think this still does not work though. The constraint is that: The addTimedEvent() function is part of the Widget class which is also in the dll, but it is instanced by the user. The other constraint is that some classes which derive from Widget call this function with their own timed event classes. Given that "he who called new must call delete" what could work given these constraints? Thanks

• EXE stops working if containing folder is renamed. MSVCP90.dll

  - by John

  This popup comes up as soon as the app is started: The program can't start because MSVCP90.dll is missing from your computer. Before anyone says "install the VC++ runtimes", wait! If I rename the folder containing my .EXE then the app runs. If I rename it back, it breaks. The app has been running for weeks without any changes to my system/VS installation (2008 SP1), we suddenly spotted this error a few days ago. Lost as to why the name of the dir is causing issues... again this has not changed in months and all our resource paths are relative anyway, e.g "../someOtherDir/...." It doesn't just do this on my PC, we have the /bin dir (the one containing EXE) in SVN and suddenly everyone started seeing the same issue, even though the binaries themselves seem just fine. Is it possible some additional data got put into SVN and that's the cause? Since it's not just one PC, there must be something either in SVN or the EXE itself... Note this popup comes before our code even gets to run.

• How do I import service references to Unity3D?

  - by Timothy Williams

  I'm attempting access a service reference in Unity. I need two: the SOAP framework and a separate service called ContentVault. The respective service URL's are: SOAP: http://api.microsofttranslator.com/V2/Soap.svc ContentVault: http://ioun.wizards.com/ContentVault.svc Both services import fine in to Visual Studio. I've tried everything I can think of but they won't work with Unity. I just get various errors (changing depending on which solution I'm trying out). I've attempted using svcutil to export the services as external scripts, but all I got was a bunch of using errors. I've tried converting the code to work with .NET 2.0 to no avail, I've even tried making the services in to .DLL's to no success. How could get these services working with Unity?

• How to update dependency during runtime in my .NET application?

  - by Louis Rhys

  I have a server-client application. Sometimes the server is updated which requires some DLLs in the client to be updated as well (The DLLs are the dependencies of the main executable). For now, we have to close the client, manually deploy the DLLs, and then start the client again. This is kind of an inconvenience because the client is an automated application, so normally it doesn't need any user intervention. Is it possible for this to be done automatically without restart or user intervention? Like, the client would download the latest DLL, and replace the current one?

• libstdc++-6.dll not found. [migrated]

  - by Molmasepic

  I have been working on a project(a game to be specific) and I feel that I should start over with different libraries. So when doing this I reinstalled Code::Blocks and setup my new libraries and includes. But as of now Im having a problem starting u[ my new project to test if all of the includes work. This problem is: libstdc++-6.dll was not found. At first i wondered if I could just find this file online, but its nowhere to be found(or at least the many places I have searched...) Soon after, I tried loading up my old project, and the same problem happened again(wierd... ._.) I was thinking its maybe my compiler, so I used my older compiler and it did the same thing! At this moment I held the problem off for tomorrow(which is today) So my question is: If anyone else had this problem, how would you solve it? Im using Code::Blocks with MinGW as the compiler on Windows Vista 32 bit.

• MSBuild: TlbImp error since upgrading to VS 2010

  - by floele

  Hi, since upgrading my project to VS2010, including the use of MSBuild v4 instead of 3.5 (and not making any other changes), I get the following build error and have no clue how to fix it (log from CC.NET): <target name="ResolveComReferences" success="false"> <message level="high"><![CDATA[C:\Programme\Microsoft SDKs\Windows\v7.0A\bin\TlbImp.exe c:\Assemblies\NMSDVDXU.dll /namespace:NMSDVDXLib /machine:X64 /out:obj\x64\Release\Interop.NMSDVDXLib.dll /sysarray /transform:DispRet /reference:c:\Assemblies\Bass.Net.dll /reference:c:\Assemblies\LogicNP.FileView.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Management.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /reference:C:\WINDOWS\assembly\GAC\stdole\7.0.3300.0__b03f5f7f11d50a3a\stdole.dll ]]></message> <error code="TI0000" file="TlbImp"><![CDATA[A single valid machine type compatible with the input type library must be specified.]]></error> <warning code="MSB3283" file="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets" line="1558" column="9"><![CDATA[Die Wrapperassembly für die Typbibliothek "NMSDVDXLib" wurde nicht gefunden.]]></warning> <message level="high"><![CDATA[C:\Programme\Microsoft SDKs\Windows\v7.0A\bin\TlbImp.exe c:\Assemblies\StarBurnX12.dll /namespace:RocketDivision.StarBurnX /machine:X64 /out:obj\x64\Release\Interop.RocketDivision.StarBurnX.dll /sysarray /transform:DispRet /reference:c:\Assemblies\Bass.Net.dll /reference:c:\Assemblies\LogicNP.FileView.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Design.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Management.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll /reference:C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /reference:C:\WINDOWS\assembly\GAC\stdole\7.0.3300.0__b03f5f7f11d50a3a\stdole.dll ]]></message> <error code="TI0000" file="TlbImp"><![CDATA[A single valid machine type compatible with the input type library must be specified.]]></error> <warning code="MSB3283" file="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets" line="1558" column="9"><![CDATA[Die Wrapperassembly für die Typbibliothek "RocketDivision.StarBurnX" wurde nicht gefunden.]]></warning> </target> Problem: A single valid machine type compatible with the input type library must be specified. It only applies to the x64 build of my project, x86 still works fine. Apparently, it tries to build a x64 interop assembly from the x86 DLL located in "C:\Assemblies". When executing the TlbImp command with the x64 DLL which is located in a different directory, it works fine. However, I don't know how I can configure my project to use different COM references for the x86 and x64 build. The OS on which the project is being compiled is WinXP x86. Building worked fine when using VS2005 + MSBuild 3.5 Any help would be highly appreciated. I tried building the upgraded project with MSBuild v3.5, but that doesn't work either. It complains about unknown NoWarn codes (probably new in 4.0).

• SetWindowLong in CustomDraw causes unhandled exception

  - by neeul

  Hello, I am making some changes to a CSliderCtrl using the Custom Draw, the control is to be used in a dialog. Here is the structure: In my MessageMap I have : ON_NOTIFY_REFLECT_EX(NM_CUSTOMDRAW, OnNMCustomdraw) The OnNMCustomdraw method looks like the following: BOOL CCustomSliderCtrl::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult) { *pResult = CDRF_DODEFAULT; LPNMCUSTOMDRAW pNMCD = reinterpret_cast<LPNMCUSTOMDRAW>(pNMHDR); switch(pNMCD->dwDrawStage) { case CDDS_PREPAINT: { //Dialogs don't receive CDRF_NOTIFYITEMDRAW notifcations by returning it as part of pResult, we must //use the following so we ensure we receive the msg SetWindowLong(pNMHDR->hwndFrom, DWL_MSGRESULT, CDRF_NOTIFYITEMDRAW); return TRUE; } case CDDS_ITEMPREPAINT: if(pNMCD->dwItemSpec == TBCD_CHANNEL) { ...SNIP... SetWindowLong(pNMHDR->hwndFrom, DWL_MSGRESULT, CDRF_SKIPDEFAULT); return TRUE; } } return FALSE; } Reading around I learnt that you had to use SetWindowLong to set the return value for the custom draw, otherwise your method will not always receive the CDDS_ITEMPREPAINT message. However, when using SetWindowLong my application will never receive the CDDS_ITEMPREPAINT and so my slider just looks like a standard slider. The application crashes when any sort of interaction takes place upon the slider, such as hovering over it or minimizing and maximizing the dialog. I snipped the TBCD_CHANNEL code as it is never reached. When running in debug mode, it crashes at the end of the AfxUnlockGlobals method, in afxcrit.cpp. Here is a stack trace: Update: Since adding debug symbols, the crash seems to be picked up at CWnd::DefWindowProc mwthod. comctl32.dll!_TrackBarWndProc@16() + 0x551 bytes user32.dll!_InternalCallWinProc@20() + 0x28 bytes user32.dll!_UserCallWinProcCheckWow@32() + 0xb7 bytes user32.dll!_CallWindowProcAorW@24() + 0x51 bytes user32.dll!_CallWindowProcW@20() + 0x1b bytes mfc90ud.dll!CWnd::DefWindowProcW(unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 1043 + 0x20 bytes C++ mfc90ud.dll!CWnd::WindowProc(unsigned int message=15, unsigned int wParam=0, long lParam=0) Line 1756 + 0x1c bytes C++ mfc90ud.dll!AfxCallWndProc(CWnd * pWnd=0x0012fdbc, HWND__ * hWnd=0x000308fe, unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 240 + 0x1c bytes C++ mfc90ud.dll!AfxWndProc(HWND__ * hWnd=0x000308fe, unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 403 C++ mfc90ud.dll!AfxWndProcBase(HWND__ * hWnd=0x000308fe, unsigned int nMsg=15, unsigned int wParam=0, long lParam=0) Line 441 + 0x15 bytes C++ user32.dll!_InternalCallWinProc@20() + 0x28 bytes user32.dll!_UserCallWinProcCheckWow@32() + 0xb7 bytes user32.dll!_DispatchClientMessage@20() + 0x4d bytes user32.dll!___fnDWORD@4() + 0x24 bytes ntdll.dll!_KiUserCallbackDispatcher@12() + 0x13 bytes user32.dll!_NtUserDispatchMessage@4() + 0xc bytes user32.dll!_DispatchMessageW@4() + 0xf bytes mfc90ud.dll!AfxInternalPumpMessage() Line 183 C++ mfc90ud.dll!CWinThread::PumpMessage() Line 900 C++ mfc90ud.dll!AfxPumpMessage() Line 190 + 0xd bytes C++ mfc90ud.dll!CWnd::RunModalLoop(unsigned long dwFlags=4) Line 4386 + 0x5 bytes C++ mfc90ud.dll!CDialog::DoModal() Line 584 + 0xc bytes C++ SetSelection.exe!CSetSelectionApp::InitInstance() Line 64 + 0xb bytes C++ mfc90ud.dll!AfxWinMain(HINSTANCE__ * hInstance=0x00400000, HINSTANCE__ * hPrevInstance=0x00000000, wchar_t * lpCmdLine=0x00020a84, int nCmdShow=1) Line 37 + 0xd bytes C++ SetSelection.exe!wWinMain(HINSTANCE__ * hInstance=0x00400000, HINSTANCE__ * hPrevInstance=0x00000000, wchar_t * lpCmdLine=0x00020a84, int nCmdShow=1) Line 34 C++ SetSelection.exe!__tmainCRTStartup() Line 578 + 0x35 bytes C SetSelection.exe!wWinMainCRTStartup() Line 403 C kernel32.dll!_BaseProcessStart@4() + 0x23 bytes So, does anyone have any insight into this matter?

• Winforms TabControl causing spurious Paint events for UserControl

  - by Tom Bushell

  For our project, we've written a WinForms UserControl for graphing. We're seeing some strange behavior when our control is sited in a TabControl - our control continuously fires Paint events, even when there is absolutely no activity by the user. We only see this in the TabControl. When we site our control in other containers such as Forms or Splitters, Paint is only fired when you'd expect e.g. when the control is first displayed, etc. Can anyone suggest why this might be happening? Here's a stack trace from a breakpoint in our control's Paint handler, if that's any help. OverlordFrontEnd.exe!OverlordFrontEnd.MainForm.graphControl_Paint(object sender = BI_BaseGraphXY.BaseGraphXY}, System.Windows.Forms.PaintEventArgs e = {ClipRectangle = {X=0,Y=0,Width=1031,Height=408}}) Line 422 C# System.Windows.Forms.dll!System.Windows.Forms.Control.OnPaint(System.Windows.Forms.PaintEventArgs e) + 0x73 bytes BI_AppCore.dll!BI_BaseGraphXY.BaseGraphXY.OnPaint(System.Windows.Forms.PaintEventArgs e = {ClipRectangle = {X=0,Y=0,Width=1031,Height=408}}) Line 377 + 0xb bytes C# System.Windows.Forms.dll!System.Windows.Forms.Control.PaintTransparentBackground(System.Windows.Forms.PaintEventArgs e, System.Drawing.Rectangle rectangle, System.Drawing.Region transparentRegion = null) + 0x16c bytes System.Windows.Forms.dll!System.Windows.Forms.Control.PaintBackground(System.Windows.Forms.PaintEventArgs e = {ClipRectangle = {X=0,Y=0,Width=1029,Height=406}}, System.Drawing.Rectangle rectangle, System.Drawing.Color backColor, System.Drawing.Point scrollOffset) + 0xbc bytes System.Windows.Forms.dll!System.Windows.Forms.Control.PaintBackground(System.Windows.Forms.PaintEventArgs e, System.Drawing.Rectangle rectangle) + 0x63 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.OnPaintBackground(System.Windows.Forms.PaintEventArgs pevent) + 0x59 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.PaintWithErrorHandling(System.Windows.Forms.PaintEventArgs e = {ClipRectangle = {X=0,Y=0,Width=1029,Height=406}}, short layer, bool disposeEventArgs = false) + 0x74 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.WmPaint(ref System.Windows.Forms.Message m) + 0x1ba bytes System.Windows.Forms.dll!System.Windows.Forms.Control.WndProc(ref System.Windows.Forms.Message m) + 0x33e bytes System.Windows.Forms.dll!System.Windows.Forms.Control.ControlNativeWindow.OnMessage(ref System.Windows.Forms.Message m) + 0x10 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.ControlNativeWindow.WndProc(ref System.Windows.Forms.Message m) + 0x31 bytes System.Windows.Forms.dll!System.Windows.Forms.NativeWindow.Callback(System.IntPtr hWnd, int msg = 15, System.IntPtr wparam, System.IntPtr lparam) + 0x5a bytes [Native to Managed Transition] [Managed to Native Transition] System.Windows.Forms.dll!System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(int dwComponentID, int reason = -1, int pvLoopData = 0) + 0x24e bytes System.Windows.Forms.dll!System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(int reason = -1, System.Windows.Forms.ApplicationContext context = {Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.WinFormsAppContext}) + 0x177 bytes System.Windows.Forms.dll!System.Windows.Forms.Application.ThreadContext.RunMessageLoop(int reason, System.Windows.Forms.ApplicationContext context) + 0x61 bytes System.Windows.Forms.dll!System.Windows.Forms.Application.Run(System.Windows.Forms.ApplicationContext context) + 0x18 bytes Microsoft.VisualBasic.dll!Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.OnRun() + 0x81 bytes Microsoft.VisualBasic.dll!Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.DoApplicationModel() + 0xef bytes Microsoft.VisualBasic.dll!Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(string[] commandLine) + 0x2c0 bytes OverlordFrontEnd.exe!OverlordFrontEnd.Program.Main() Line 36 + 0x10 bytes C# [Native to Managed Transition] [Managed to Native Transition] mscorlib.dll!System.AppDomain.ExecuteAssembly(string assemblyFile, System.Security.Policy.Evidence assemblySecurity, string[] args) + 0x3a bytes Microsoft.VisualStudio.HostingProcess.Utilities.dll!Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() + 0x2b bytes mscorlib.dll!System.Threading.ThreadHelper.ThreadStart_Context(object state) + 0x66 bytes mscorlib.dll!System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, object state) + 0x6f bytes mscorlib.dll!System.Threading.ThreadHelper.ThreadStart() + 0x44 bytes

• Rank Source Control Optionsl-VSS vs CVS vs none vs your own hell

  - by Roman A. Taycher

  It seems like a lit of people here and on many programmer wikis/blogs/ect. elsewhere really dislike VSS. A lot of people also have a serious dislike for cvs. In many places I have heard a lot of differing opinions on whether or not using vss or cvs is better or worse then using no source control, please rate the worst and explain why!!!!! you rated them this way. Feel free to throw in your own horrible system in the rankings. If you feel it depends on the circumstances try to explain the some of the different scenarios which lead to different rankings. (note:I see a lot of discussion of what is better but little of what is worse.) second note: while both answers are nice I'm looking less for good replacements and more for a comparison of which is worse and more importantly why!!!!!

• Lost in UTF-8 hell. (Django and Python)

  - by user140314

  I am working through the Django RSS reader project here. The RSS feed will read something like "OKLAHOMA CITY (AP) — James Harden let". The RSS feed's encoding reads encoding="UTF-8" so I believe I am passing utf-8 to markdown in the code snippet below. The em dash is where it chokes. I get the Django error of "'ascii' codec can't encode character u'\u2014' in position 109: ordinal not in range(128)" which is an UnicodeEncodeError. In the variables being passed I see "OKLAHOMA CITY (AP) \u2014 James Harden". The code line that is not working is: content = content.encode(parsed_feed.encoding, "xmlcharrefreplace") I am using markdown 2.0, django 1.1, and python 2.4. What is the magic sequence of encoding and decoding that I need to do to make this work? Thanks.

  Do you think the new dynamic type for C# is a serious drawback regarding the advantages of a strong typed language or do you think the advantages (like getting around those heavily reflections) outweigh the risks?

• latex padding / margin hell

  - by darren

  hi everyone I have been wrestling with a latex table for far too long. I need a table that has has centered headers, and body cells that contain text that may wrap around. Because of the wrap-around requirement, i'm using p{xxx} instead of l for specifying cell widths. The problem this causes is that cell contents are not left justified, so the look like spaced-out junk. To fix this problem I'm using \flushleft for each cell. This does left justify contents, but puts in a ton of white space above and below the contents of the cell. Is there a way to stop \flushleft (or \center for that matter) to stop adding copious amounts of verical whitespace? thanks \begin{landscape} \centering % using p{xxx} here to wrap long text instead of overflowing it \begin{longtable}{ | p{4cm} || p{3cm} | p{3cm} | p{3cm} | p{3cm} | p{3cm} |} \hline & % these are table headings. the \center is causing a ton of whitespace as well \begin{center} \textbf{HTC HD2} \end{center} & \begin{center} \textbf{Motorola Milestone} \end{center} & \begin{center} \textbf{Nokia N900} \end{center} & \begin{center} \textbf{RIM Blackberry Bold 9700} \end{center} & \begin{center} \textbf{Apple iPhone 3GS} \end{center} \\ \hline \hline % using flushleft here to left-justify, but again it is causing a ton of white space above and below cell contents. \begin{flushleft}OS / Platform \end{flushleft}& \begin{flushleft}Windows Mobile 6.5 \end{flushleft}& \begin{flushleft}Google Android 2.1 \end{flushleft}& \begin{flushleft}Maemo \end{flushleft}& \begin{flushleft}Blackberry OS 5.0 \end{flushleft}& \begin{flushleft}iPhone OS 3.1 \end{flushleft} \\ \hline

• ASP.net Text Box Enter button pressed hell

  - by Morgeh

  Basically I have an asp.net website with login and search pages. Currently, I have no idea why, when ever a user hits enter in either of the login text boxes (user name/password) or in the Seach text box, the website is redirected to the default page. I have no idea why this is happening, I've tried setting defaultButton on both the panel containing the search and the login panel but that doesnt seem to work. I've also tried catching the key press event with javascript which isnt working either. I have no idea what event is being fired and why, or why it seems to override everything I try to do. Anyone seen anything like this before?

  It seems like a lot of people here and on many programmer wikis/blogs/ect. elsewhere really dislike VSS. A lot of people also have a serious dislike for cvs. In many places I have heard a lot of differing opinions on whether or not using VSS or cvs is better or worse then using no source control, please rate the worst and explain why!!!!! you rated them this way. Feel free to throw in your own horrible system in the rankings. If you feel it depends on the circumstances try to explain the some of the different scenarios which lead to different rankings. (note:I see a lot of discussion of what is better but little of what is worse.) second note: while both answers are nice I'm looking less for good replacements and more for a comparison of which is worse and more importantly why!

• a script translatable to JavaScript with callback-hell automatic avoider :-)

  - by m1uan

  I looking for "translator" for JavaScript like already is CoffeScript, which will be work for example with forEach (inspired by Groovy) myArray.forEach() -> val, idx { // do something with value and idx } translate to JavaScript myArray.forEach(function(val, idx){ // do something with value and idx }); or something more usefull... function event(cb){ foo()-> err, data1; bar(data1)-> err, data2; cb(data2); } the method are encapsulated function event(cb){ foo(function(err,data1){ bar(data1, function(err, data2) { cb(data2); }); }); } I want ask if similar "compiler" to JavaScript like this even better already doesn't exists? What would be super cool... my code in nodejs looks mostly like this :-) function dealer(cb){ async.parallel([ function(pcb){ async.watterfall([function(wcb){ first(function(a){ wcb(a); }); }, function(a, wcb){ thirt(a, function(c){ wcb(c); }); fourth(a, function(d){ // dealing with “a” as well and nobody care my result }); }], function(err, array_with_ac){ pcb(array_with_ac); }); }, function(pcb){ second(function(b){ pcb(b);}); }], function(err, data){ cb(data[0][0]+data[1]+data[0][1]); // dealing with “a” “b” and “c” not with “d” }); } but, look how beautiful and readable the code could be: function dealer(cb){ first() -> a; second() -> b; third(a) -> c; // dealing with “a” fourth(a) -> d; // dealing with “a” as well and nobody care about my result cb(a+b+c); // dealing with “a” “b” and “c” not with “d” } yes this is ideal case when the translator auto-decide, method need to be run as parallel and method need be call after finish another method. I can imagine it's works Please, do you know about something similar? Thank you for any advice;-)

• preg_replace hell

  - by Jason

  I'm trying to use preg_replace to get some data from a remote page, but I'm having a bit of an issue when it comes to sorting out the pattern. function getData($Url){ $str = file_get_contents($Url); if(strlen($str)>0){ preg_match("/\<span class=\"SectionHeader\"\>title\</span>/<br/>/\<div class=\"header2\"\>(.*)\</div\></span\>/",$str,$title); return $title[1]; } } Here's the HTML as is before I ended up throwing a million slashes at it (looks like I forgot a part or two): <span class="cell CellFullWidth"><span class="SectionHeader">mytitle</span><br/><div class="Center">Event Name</div></span> Where Event Name is the data I want to return in my function. Thanks a lot guys, this is a pain in the ass.

• Avoiding try/catch hell in my web pages

  - by Shaun_web

  I am writing an ASP.NET website, which is a new framework for me. I find that I have a try/catch block in literally every method of my codebehind. All these try/catch blocks do is catch the exception and then pop-up an error message to the user. Isn't there some sort of global error handler in ASP.NET? It's worth noting that my error handling is within control (ASCX) pages, and I would like a way to simply get each ASCX to handle its own errors without forcing all error handling just to a single master page or a redirect...

• Why in the hell is this happening?

  - by user202411

  I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).

• Moving from Silverlight 4 Beta to RC - Part 2

  In my previous post I talked about updating my development environment from Silverlight 4 Beta to Silverlight 4 RC (release candidate). After updating, I opened the solution for my Task-It project and found that several things were broken. I would've been surprised if it just worked as is! What disappointed me is that after spending a decent amount of time searching the web, I could not find information telling me what I needed to update/change...and wouldn't it be nice if there was a wizard to update it for you? What changed? I wish I had made notes along the line of each of the things I found, but here are a few that I can recall: In the Web project, the following dll's no longer exist: System.Web.DomainServices.dll System.Web.DomainServices.LinqToSql.dll (if you are using the Entity Framework I believe that one is System.Web.DomainServices.EntityFramework.dll) System.Web.Ria.dll In the Silverlight project: System.Windows.Ria.dll I'm not positive which new assemblies need to be referenced for your project, but I'm going to list the ones I think you need. One way to verify is to create a new Silverlight application with support for WCF RIA Services and see which dlls are included. In the Web project: System.Data.Entity.dll System.ServiceModel.DomainServices.EntityFramework.dll (I've moved from LinqToSql to EntityFramework, so I'm not sure which one the LinqToSql stuff comes from) System.ServiceModel.DomainServices.Hosting.dll System.ServiceModel.DomainServices.Server.dll In the Silverlight project: System.ServiceModel.DomainServices.Client.dll System.ServiceModel.DomainServices.Client.Web.dll System.ServiceModel.Web.Extensions.dll Where are these dll's? These all live in either the Silverlight or RIA Services subdirectories under:         C:\Program Files\Microsoft SDKs Of if you are on a 64-bit machine like me:         C:\Program Files (x86)\Microsoft SDKs Wrap up Good luck, and I hope this helps to get you back in business! If anyone finds anything that I've missed, please enter a comment and I'll update the post accordingly.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• using ILMerge with .NET 4 libraries

  - by Sarah Vessels

  I'm having trouble using ILMerge in my post-build after upgrading from .NET 3.5/Visual Studio 2008 to .NET 4/Visual Studio 2010. I have a Solution with several projects whose target framework is set to ".NET Framework 4". I use the following ILMerge command to merge the individual project DLLs into a single DLL: if not $(ConfigurationName) == Debug if exist "C:\Program Files (x86)\Microsoft\ILMerge\ILMerge.exe" "C:\Program Files (x86)\Microsoft\ILMerge\ILMerge.exe" /lib:"C:\Windows\Microsoft.NET\Framework64\v4.0.30319" /lib:"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies" /keyfile:"$(SolutionDir)$(SolutionName).snk" /targetplatform:v4 /out:"$(SolutionDir)bin\development\$(SolutionName).dll" "$(SolutionDir)Connection\$(OutDir)Connection.dll" ...other project DLLs... /xmldocs If I leave off specifying the location of the .NET 4 framework directory, I get an "Unresolved assembly reference not allowed: System" error from ILMerge. If I leave off specifying the location of the MSTest directory, I get an "Unresolved assembly reference not allowed: Microsoft.VisualStudio.QualityTools.UnitTestFramework" error. The ILMerge command above works and produces a DLL. When I reference that DLL in another .NET 4 C# project, however, and try to use code within it, I get the following warning: The primary reference "MyILMergedDLL" could not be resolved because it has an indirect dependency on the .NET Framework assembly "mscorlib, Version=4.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.65535.65535" than the version "4.0.0.0" in the current target framework. If I then remove the /targetplatform:v4 flag and try to use MyILMergedDLL.dll, I get the following error: The type 'System.Xml.Serialization.IXmlSerializable' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. It doesn't seem like I should have to do that. Whoever uses my MyILMergedDLL.dll API should not have to add references to whatever libraries it references. How can I get around this?

• Unregistering COM dll with a C# Setup Project

  - by lb

  Hi All. I've been stuck on this one for a while. I'll try explain in the simplest terms and at the best of my knowledge. I will honour any help. I've got a C# project which uses a VB6 compiled ActiveX DLL that I'm constantly updating. I compile the setup project, send it to the client and they run the setup. When building the updated setup project, I would increase the 'Version' of the setup project so it wouldn't bother with 'Another version is already installed'. What started happening after a few updates I began to notice the DLL would not be updated to the new version in the installer. The client computer had the original DLL both installed and registered. First symptom: method not found exceptions from the client C# code. This is not a shared DLL and only this application needs it. I've noticed that when uninstalling the application (through the usual procedure) the DLL is also not removed from the application folder although I would set this file's property 'Permanent' to false. The registration entries in the registry are mantained also. I do update in VS6.0 the version of the DLL (usually increase the build number) before building it. Then in VS2008, I remove it from the References, and add it again from the 'Browse tab', without re-registering it on my dev machine and adding it from the COM tab. I've thought of these options. Custom step in Setup project to regsvr32.exe /u 'hardcoded path of my dll' at uninstall (ugly) Somehow find out how the 'Isolate' property can work for me without registering Find out how to execute setup project 'Conditions' that would actually check the version of the library and to update the file accordingly at every install) Any help would be incredibly welcome.

• C# to unmanaged dll data structures interop

  - by Shane Powell

  I have a unmanaged DLL that exposes a function that takes a pointer to a data structure. I have C# code that creates the data structure and calls the dll function without any problem. At the point of the function call to the dll the pointer is correct. My problem is that the DLL keeps the pointer to the structure and uses the data structure pointer at a later point in time. When the DLL comes to use the pointer it has become invalid (I assume the .net runtime has moved the memory somewhere else). What are the possible solutions to this problem? The possible solutions I can think of are: Fix the memory location of the data structure somehow? I don't know how you would do this in C# or even if you can. Allocate memory manually so that I have control over it e.g. using Marshal.AllocHGlobal Change the DLL function contract to copy the structure data (this is what I'm currently doing as a short term change, but I don't want to change the dll at all if I can help it as it's not my code to begin with). Are there any other better solutions?
