    - Replacing dbghelp.dll with the newest version in VS 2003? Hi, would it be a good idea to replace dgbhelp.dll with the newest version from debugging tools Replacing the old header and compiling & distributing with the new dll I currently use VS 2003 and program generates minidumps when it crashes. Best wishes, Andy Tag: Visual C++ General Creating CoClass in ATL using VS 2005 Visual C++

    - command line options for stripped pdb Hi All, I like to have my project generate stripped pdb file in command line option. I tried with the following options in my command line: msdev myproject.dsw /MAKE /LINK /PDBSTRIPPED:Test.pdb there was no error once I run the command, but it didn't generate stripped pdb file named "test.pdb" in the folder. I also tried the other way as: Link /PDBSTRIPPED:Test.pdb but it didn't work either. Anyone has any suggestion Thanks, vcfan Tag: Visual C++ General Creating CoClass in ATL using VS 2005 Visual C++

    - passing control handle to unmanaged directx dlls to paint - result is flickering! Hi, I have a third party unmanaged DLLs which requries a window handle to do some painting on. My attempts have been to pass the control::handle property to this DLLs. The DLLs declaration expects a void* hWnd. Below is the declaration. CyResult CyDisplayEx:: Open ( void * aWindow , unsigned short aColumns = 1 , unsigned short aRows = 1 , bool aFullScreen = false ) [virtual] What I did was is follows. Panel* test = new Panel(); System:: Intptr handle = test->Handle; void __pin* hwnd = (void*)handle; CyDisplayEx:: Open(hwnd, 1,1, false); The result & problem The unmanaged DLL starts painting in the window area. It continues to update with significant flickering. At this point, I have not managed any of the paint event to that window. Additional information about the 3rd party DLL. I know that the DLL uses directdraw to paint in the window. It also has the following notes: Note: On Windows, the aWindow parameter must be a valid HWND (WIN32 SDK). It is important that the user’s window handling call the following functions on specific Windows events: WM_MOVE ==> OnMove( unsigned int aPosX, unsigned int aPosY ) ; WM_SIZE ==> OnSize( unsigned int aSizeX, unsigned int aSizeY ) ; WM_PAINT ==> OnPaint() ; I have been strugling with this for almost a week If anyone has any insight, PLEASE don't hesitate to help.

    - CryptUI.dll I recently created an application that is using a function in CryptUI.dll. I developed this application on a Vista machine, and then tested it on an XP machine. Everything works great. However, I moved the program to a Windows 2003 system and the program fails. I get an error message that says Windows can't find the entry point for my function (CryptUIDlgSelectCertificateFromStore) in CryptUI.dll. I tried copying the dll over from my XP machine to my Windows 2003 machine, but that didn't work either. Does anyone have any ideas how I can solve this problem Thanks in advance.

    - "Unresolved external symbol" after upgrading to VS05 Hi All, I have a project that build and worked fine all the way through Visual Studio 2003. After upgrading to VS2005 and rebuilding the two dependent libraries I am receiving a linker error on the parent DLL stating: Error 1 error LNK2001: unresolved external symbol _hInstDLL stdafx.obj Error 2 error LNK2001: unresolved external symbol _hInstGenDLL stdafx.obj There is a common header included in one of the libraries and the parent DLL. All files are C++. I can't get rid of the "extern "C"" section because of legacy stuff elsewhere. That header file contains amongst others the following code: #ifdef __cplusplus extern "C" { #endif extern HINSTANCE hInstDLL; extern HINSTANCE hInstGenDLL; One of the source files in the library contains the following code fragment: extern "C" { HINSTANCE hInstDLL1Way; HINSTANCE hInstGenDLL; } As you can see ( and not for the lack of a blinking cursor in this window on my FireFox browser ), I am defining the two variables. The library builds cleaning with no errors or warnings. The main DLL builds cleanly to, but now throws a the two linker errors, which is really one linker error. The old version of VS (2003) correctly located the two symbols in the library. What do I need to do now Thanks in advance, Marci Weinberger Tag: Visual C++ General Creating CoClass in ATL using VS 2005 Visual C++

    - Semaphores Hi, I'm learning about semaphore, and I'm trying to write a simple program using it. The program: each time a semaphore reaches 4 (in his counter), it will zero it self and start again. Can any one show how to do that MyProgram: HANDLE X; void main() { X = CreateSemaphore(NULL, 0, 4L, NULL); CreateThread( NULL, 0, X_func , Data, 0, NULL); CloseHandle(X); } DWORD WINAPI X_func(LPVOID data) { MyData* Data = ((MyData*)data); while ( true ) { WaitForSingleObject(X , INFINITE); ReleaseSemaphore(HydrogenReady, 1, NULL ) } } Tag: Visual C++ General Creating CoClass in ATL using VS 2005 Visual C++

Precisely, I have to dump log data to a log file, these data could be written with different human languages as I mentioned above.

    - LNK4099 problem. I have a solution with 7 projects. 6 of them are static libraries, 1 is an executable. Obviously executable links to all the statics. All /mdd(/md) . All Zi(ZI). No third party components, but Microsoft's. If I pre-build static libraries outside in another solution - I'll get this warning. If I do rebuild all , which kind of defeats the purpose, I do not get that warning. It seems like a bug in the Visual studio to me, but I might be wrong.

    - Always Recompile unnecessary files (not modified files) [SOLVED] Hi, I'm having trouble with Visual Studio .NET 2003. I was developing an application for one year ago and when I clicked to build solution, it compiles only the files that where modified. Since one month ago I have reinstalled Windows and Visual Studio and when I try to build the project, it always compile all the files in the project. I don't understand what's happening because I didn't changed any option. Thanks, -------------------SOLUTION------------------- Hi, finally I have found the problem. I have a "definitions.h" file that contains some definitions. One of this was the PI number. Now I have deleted this definition and I use the M_PI constant from "math.h". I don't understand why but now the project only builds if I make any change and only compile these files. Tag: Visual C++ General Creating CoClass in ATL using VS 2005 Visual C++

    - Problem while trying to implement an interface exposed by a type library in VC++ Hello, I have an MFC application that has been built using VC++ 6.0. It is a 'full server' executable. I import a COM dll into my VC++ project by using the following: # import <COM_DLL> no_namespace no_implementation raw_interfaces_only named_guids This creates the type library for the dll (with the name COM_DLL.tlh). The COM_DLL that I am importing has an interface. This (dual) interface is being exposed as a "struct __declspec " in the .tlh file. I want to implement this interface, as this is essentially for a callback. I am new to the world of VC++ and don't know how to proceed ahead :( Searching over MSDN did not help much either - perhaps I am not searching for the right thing. I would highly appreciate if someone could give me some pointers on how to proceed ahead with implementing the interface. Thanks, Ankit Tag: Visual C++ General Creating CoClass in ATL using VS 2005 Visual C++

    - Let's talk about the C++ox Stroller, you can find an overview of C++0x proposals here. http://en.wikipedia.org/wiki/C%2B%2B0x Also, an article from Bjarne Stroustrep: http://www.artima.com/cppsource/cpp0x.html I would advise any Windows developer to know both C++ and C#, and when the need arises for mixed C++ and .NET (managed) programming, the C++/CLI language. C++0x (where x is likely '9' for 2009) will make very useful advances to the language, but your investigation today should be academic rather than practical.

    - Can you use C++ to create a windows native code application? Hello i am trying to write a very simple program that will display a form to the user with two check boxes, and depending on these check boxes launch separate exe files. So my questions are: 1) Can this be done in visual studio 2005 2) If it can what kind of project do i need to create in order to write windows native code (I just need to be able to run this application without any of the .NET Frameworks installed on the users machine) Thanks in advance for any help you can give me.

    - CFileDialog As you can see, the OFN_ENABLEHOOK is currently disabled in the code I provided to you. Anyhow: 1. this flag is inserted automatically by the CFileDialog contructor (I read the source code) 2. DoModal asserts if this flag is not used 3. I am not trying to use any special hook - just the default provided by MFC, which works fine with File | Open. My code is in fact almost a replica of the code that the framework uses when it processes OnFileOpen (again, I read the MFC source code) Thanks.

    - Failed To Find Module - C++ Interop problem... xxxx.dll is the generic C runtime dynamic linkage library, xxxxD.dll is the same but for DEBUG mode usage. Use them can let your programs' module become smaller. For example, if your application runing A.exe and it linked with B.dll , both called strcmp() function. The strcmp is a generic C function, as you known, then: Specified the 'multi-thread debug dll' to your project, msvcr80d.dll will be used. Specified the 'multi-thread dll' to your project, msvcr80.dll will be used. The msvcm80.dll is the module for managed version. the other two is standart module. The module A and B will share strcmp function(binary code only) but have to call one in the module msvcxxxx.dlls. If your project built without 'xxxx dll' option, A and B will contains their own strcmp function, which is linked to the modules staticly. Unless you'v known exactly what will happen and the way the program acted in is in your hope, you'd better not let the module built with different ways works together.

Hi All,

I recently started working in VS2005 environment, and having a background of VC6.0. I just created a smple ATL application under 2005, and just wondering if any option is available in the IDE for creating a coclass of the ATL component, as we does in VC6.0 IDE by using Insert->New ATL Object Please help me on the same. Thanks in advance.

Regards,

I think you can do it in the context menu of class view "Add Class".
