Thanks for the tip, didn't know that (and for the URL). I changed the code
to

 HDC hDC;
        PAINTSTRUCT ps;
        case WM_PAINT:
        {
            char str[]="Display text";
            hDC=BeginPaint(hwnd,&ps);
            TextOut(hDC,100,100,str,lstrlen(str));
            EndPaint(hwnd,&ps);
        }

and it works. Also, thanks to Carlos.
