Thread: No debug output in Visual Studio

Hello

Im trying to debug WM_KEYDOWN messages in Visual Studio 2022 in order to see why I dont get Ctrl-A message in the second edit box but I dont see any message in the debug output window.

Im sending Ctrl-A to the hOutput edit box but the focus arrives on the hCombo1 combo box.

Code:

#define BUILD_WINDOWS
#include "Capitalizor.h"

LRESULT CALLBACK WindowProcedure(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

    HFONT    hBig, hFont;
