Title Body

I try to get the name of executable name of all of my launched windows and my problem is that: I use the method UINT GetWindowModuleFileName( HWND hwnd, LPTSTR lpszFileName, UINT cchFileNameMax); And I don't understand why it doesn't work. Data which I have about a window are: -HWND AND PROCESSID The error is: e.g: HWND: 00170628 ProcessId: 2336 WindowTitle: C:\test.cpp - Notepad++ GetWindowModuleFileName(): C:\test.exe HWND: 00172138 ProcessId: 2543 WindowTitle: Firefox GetWindowModuleFileName(): C:\test.exe HWND: 00120358 ProcessId: 2436 WindowTitle: Mozilla Thunderbird GetWindowModuleFileName(): C:\test.exe Note: test.exe is the name of my executable file, but it is not the fullpath of Notepad++... and it make this for Mozilla Thunderbird too... I don't understand why I use the function like this: char filenameBuffer[4000]; if (GetWindowModuleFileName(hWnd, filenameBuffer, 4000) > 0) { std::cout << "GetWindowModuleFileName(): " << filenameBuffer << std::endl; } Thank you for your response.
