Hallo,

Einen Button erstellst du mit CreateWindow () , den du in der Nachrichtenschleife konstruierst, und beim Event WM_CREATE anzeigen laesst. Die Dokumentation zu dieser Funktion findest du in der MSDN hier. (http://msdn2.microsoft.com/en-us/library/ms632679.aspx). Ein Beispielcode, ersetze deine Callback Funktion einfach durch diese:

Code: Alles auswählen
LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
   static HWND hButton;
   switch (message)
   {
     case WM_CREATE:
     {
        hButton = CreateWindow( "button",
        "Testbutton",
        WS_CHILD | WS_VISIBLE,
        0, 0, 0, 0,
        hwnd,
        NULL,
        ((LPCREATESTRUCT) lParam) -> hInstance,
        NULL);
        return 0;
     }
   }
}


Weiterhin empfehle ich dir ein Tutorial zur WinAPI: www.win-api.de
