I want to use it during uninstall procedure to warn the user ahead. The procedure should work for W2000+, hence Vista API's are not allowed. This seems to catch some conflicts: if( GetFileAttributes( lpPath ) == INVALID_FILE_ATTRIBUTES ) { // File does not exist } else { BOOL bCanDelete = FALSE ; HANDLE hFile = CreateFile( path, ...
I am using MSVC 6.0 to call a macro in the Win32API and I'm getting an access violation. I know that the pointers I'm passing to the macro contain valid addresses, though they're evidently not pointing to the correct data. The macro accepts multiple pointers, and I'm not sure which pointer is erroneous, so I'd like to use MSVC's debugg...

I want to set the embedded icon for my executable console program to a custom icon. I know this is pretty much the same question as this one here, but I'm using Visual C++ 2008 Express Edition, and the Resources View is not available (and the Project-context-menu->Add->Resource... is grayed out), so I'm at loss here. Will I have to upgr...
I am compiling my project with msvc++ 2008. I have added a reference path in project properties to ./lib, which is the directory that contains the file freeglut.lib. I have been very careful to organize everything nicely, and still msvc++ does not find the file :(. I checked the build log, to see that no where in the build command line d...
I want to make win32 apps and games. Is there any major differences between C++ and Visual C++? What should I use. ...
I have several DLLs in my project that are defined to create their *.pdb file (debug info) inside the same folder. The problem is that the only *.pdb file that actually exist inside this folder is the one that belongs to the last compiled DLL. As a result I can debug only the last project (each compilation deletes all the *.pdb in the fo...
Hi all, I'm trying to link up some of the boost stuff with a visual C++ project of mine and am not sure what the best way to do this is, I'm specifically interested in the singleton class. ...
Currently Visual Studio just starts cl.exe for C++ source compilation. cl.exe needs to be in one of folders listed on the %PATH% environment variable. Since there're separate versions of cl.exe for 32-bit and 64-bit compilation in order to compile a 32-bit project after compiling a 64-bit project it is necessary to restart Visual Studio...
This is child's play, but I'm a bit of a vc n00b. I get an error: error C2143: syntax error : missing ',' before '<'. on the second line of the following code: template<int i, int j> class B : public A<i, j> { } template<int i, int j> class A { } Thanks for the help! ...
ATL provides a bunch of macros for creating so-called COM maps - chains of rules of how the QueryInterface() call behaves on a given object. The map begins with BEGIN_COM_MAP and ends with END_COM_MAP. In between the the following can be used (among others): COM_INTERFACE_ENTRY, COM_INTERFACE_ENTRY2 - to ask C++ to simply cast this cla...
Hi guys, I have issue in service created using VC++ code. as my ServiceMain function ends. it returns following error in End of the function(in release it crashes.)

Suppose my COM object implements two or more COM interfaces: class CMyClass : public IPersistFile, public IPersistStream { }; when implementing QueryInterface() I need to be able to return an IUnknown* pointer. Since both base interfaces are derived from IUnknown I cannot upcast implicitly - such upcast would be umbiguous. To upcast e...
Assume I have a class implementing two or more COM interfaces: class CMyClass : public IInterface1, public IInterface2 { }; Almost every document I saw suggests that when I implement QueryInterface() for IUnknown I explicitly upcast this pointer to one of the interfaces: if( iid == __uuidof( IUnknown ) ) { *ppv = static_cast<IIn...
I'm new to COM. What exactly is the advantage of replacing: L"String" with CComBSTR(L"String") I can see a changelist in the COM part of my .NET application where all strings are replaced in this way. Would like to know what is the need for this. ...

I'm wanting to dynamically resize a CButton to the width of the text within it. Is there either a built-in way to do this in MFC, or a way of calculating the pixel width of some specified text (so that I can use CWnd::SetWindowPos)? ...
Moving a project to different computer and trying to compile it there, produces the following error: CVTRES : fatal error CVT1106: cannot write to file .\Debug\Project.res : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt Environment is Visual C++ 6, but quick search from the internet hinted that it mig...
When using multiple inheritance C++ has to maintain several vtables which leads to having "several views" of common base classes. Here's a code snippet: #include "stdafx.h" #include <Windows.h> void dumpPointer( void* pointer ) { __int64 thisPointer = reinterpret_cast<__int64>( pointer ); char buffer[100]; _i64toa( thisPoin...
