LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)

see that line of code? well the Message contains the WM_COMMAND and others stuff.. there are also two parameters.. the wParam and the lParaw.. well the wParam contains the id of the button (or anything else) that recieved a WM_COMMAND message.

For example:

      case WM_COMMAND:
         switch(LOWORD(wParam))
         {
            case CM_FILE_OPEN:
               DoFileOpenSave(hwnd, FALSE);
            break;
            case CM_FILE_SAVEAS:
               DoFileOpenSave(hwnd, TRUE);
            break;
            case CM_FILE_EXIT:
               PostMessage(hwnd, WM_CLOSE, 0, 0);
            break;
            case CM_ABOUT:
               MessageBox (NULL, "File Editor for Windows !\n Using the Win32 API" , "About...", 0);
         }
