pues hoy empeze con la WINAPI (un rollazo por cierto ) y tengo un error al copilar un sencillo menu en CODE::BLOCKS. No se donde esta el error asi que agradecería que me lo dijesen.
Código:

Ese es el codigo entero, y la parte donde me falla es esta:ç
Código:
switch (message) /* handle the messages */
{
case WM_CREATE:
HMENU menu1,menu2;
menu1= CreateMenu();
menu2= CreateMenu();
AppendMenu (menu2, MF_STRING, MENSAJE, "mensaje");
AppendMenu (menu1, MF_STRING | MF_POPUP| (UINT) menu2, "menu");
SetMenu (hwnd, menu1);
break;
case WM_DESTROY:
PostQuitMessage (0); /* send a WM_QUIT to the message queue */
break;
default: /* for messages that we don't deal with */
return DefWindowProc (hwnd, message, wParam, lParam);
}
return 0;
{
case WM_CREATE:
HMENU menu1,menu2;
menu1= CreateMenu();
menu2= CreateMenu();
AppendMenu (menu2, MF_STRING, MENSAJE, "mensaje");
AppendMenu (menu1, MF_STRING | MF_POPUP| (UINT) menu2, "menu");
SetMenu (hwnd, menu1);
break;
case WM_DESTROY:
PostQuitMessage (0); /* send a WM_QUIT to the message queue */
break;
default: /* for messages that we don't deal with */
return DefWindowProc (hwnd, message, wParam, lParam);
}
return 0;
Y la verdad no encuentro el error, espero que vosotros me lo digais. Gracias y Un salu2!
Por cierto el error que me da es este:
