      • Using VS 2005 and I've been googling for the last several hours and keep getting the sdame 2 answers to the "cannot convert char[...] to LPCWSTR" or some other variation of that. The "offending" line of code: MessageBox(hWnd, szBuffer, NULL, MB_OK); The first answer is useless - using L"" or _T(x) - since I want to use a variable, not a constant.

      • ( sorry for cross posting with the C# forum) I'm trying to integrate an unmanaged VC++ MFC GUI application with a new C# library. The C# library is a GIS library (i.e., it draws maps to the screen), and I'd like to (somehow) tell it to draw to one of the HWND window handles that was defined in VC++. The C# library allows the user to set the window handle for it to use (it accepts the standard I

I can get the MouseMove event to fire if I add a message map etc to the dialog cpp file and header, but when I add a picture box, there doesn't appear to be a class file to add any code to for the MouseMove event.

      • Please modify the IDE so that when a break point is encountered by the debugger VS does not take focus from another application. This is a royal pain since I can be in another application such as Outlook and actively typing when the breakpoint is encountered. At that point the IDE starts modifying whatever file the breakpoint is in. Then I have to endure a lengthy wait as the edit&conti

If I do it outside the constructor, I don't. The leak exhibits itself as increasing memory usage as the program runs. The SymGetSymFromAddr64() call seems to be the one doing the leak; if I comment it out, then
