Win32 i DLL

Nå ny opgave til de kloge hoveder..

Jeg skal bruge en splash screen skrevet i REN win32 der ligger i en DLL


til det formål har jeg det følgende kode :


//--------------------------------------
//  DLL Kode
//--------------------------------------

#include <windows.h>
#define WIN32_LEAN_AND_MEAN

#ifdef ATOMIC_VC6 //VC++ 6.0
  #define EXPORT __declspec(dllexport)
#else //Borland 5.0x
  #define EXPORT _export
#endif

    WNDCLASS WinClass;
    HINSTANCE Inst;
    HRGN hRegion;
    HWND Handle;
    MSG  Msg;
    HANDLE AppFrameLogo;
    int xoff,yoff,xsize,ysize;
    long bmxsize,bmysize;
    PAINTSTRUCT ps;
    BITMAPV4HEADER bmhdr;
    int bcountx;
    int bcounty;
    int brestx;
    int bresty;


    LRESULT CALLBACK SPASHWndProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
    {
        switch(uMsg)
        {
        case WM_PAINT:
            {

                    BeginPaint(Handle,&ps);
                    RECT wr;

                    GetClientRect(Handle,&wr);
                    xoff=0;
                    yoff=0;
                    xsize=wr.right;
                    ysize=wr.bottom;

                    HDC hdc = ps.hdc;
                    HDC cdc = CreateCompatibleDC(hdc);
                    SelectObject(cdc,AppFrameLogo);

                    ZeroMemory(&bmhdr,sizeof(bmhdr));
                    bmhdr.bV4Size=sizeof(bmhdr);
                    GetDIBits(cdc, (HBITMAP)AppFrameLogo,0,0,0,(tagBITMAPINFO *) &bmhdr,DIB_PAL_COLORS);
                    bmxsize=bmhdr.bV4Width;
                    bmysize=bmhdr.bV4Height;

                    bcountx=(xsize / bmxsize)+1;
                    bcounty=(ysize / bmysize)+1;
                    brestx=(xsize % bmxsize);
                    bresty=(ysize % bmysize);

                    for (int cw=0;cw<bcountx;cw++)
                      for (int ch=0;ch<bcounty;ch++)
                        BitBlt(hdc,xoff+(cw*bmxsize),yoff+(ch*bmysize),bmxsize,bmysize,cdc,0,0,SRCCOPY);

                    DeleteDC(cdc);
                    EndPaint(Handle,&ps);
                return 0;
            }
/*
        case WM_DESTROY:
            PostQuitMessage(0);
            break;
*/
        default:

            return DefWindowProc(hwnd, uMsg, wParam, lParam);
      }
      return 0;
    }

    #define BITMAPWIDTH  500
    #define BITMAPHEIGHT 100

extern \"C\" int EXPORT LaunchSplashScreen(HINSTANCE hInstance)
    {
      Inst = hInstance;

      WinClass.style              = CS_CLASSDC | CS_PARENTDC;
      WinClass.lpfnWndProc        = &SPASHWndProc;
      WinClass.hInstance          = Inst;
      WinClass.lpszClassName      = \"KBA_SPLASH_SCREEN\";
      WinClass.hCursor            = LoadCursor(0, IDC_ARROW);

      RegisterClass(&WinClass);

      POINT ScreenCenter;
      ScreenCenter.x = GetSystemMetrics(SM_CXSCREEN) /2;
      ScreenCenter.y = GetSystemMetrics(SM_CYSCREEN) /2;

      int Left = ScreenCenter.x -  (BITMAPWIDTH / 2);
      int Top = ScreenCenter.y - (BITMAPHEIGHT /2);

      Handle = CreateWindowEx(WS_EX_DLGMODALFRAME, \"KBA_SPLASH_SCREEN\", \"\",  WS_VISIBLE | WS_POPUP , Left, Top, BITMAPWIDTH, BITMAPHEIGHT, 0, 0, Inst, 0);


      AppFrameLogo=LoadImage(0,\"KeyBalance Logo.bmp\",IMAGE_BITMAP,0,0,LR_LOADFROMFILE);

      if (!AppFrameLogo)
          return 0;

      UpdateWindow(Handle);

      while(GetMessage(&Msg, 0, 0, 0))
      {
          TranslateMessage(&Msg);
          DispatchMessage(&Msg);
      }

      return Msg.wParam;

  return 0;
}


BOOL APIENTRY DllMain( HANDLE hModule,  DWORD  ul_reason_for_call, LPVOID lpReserved)
{
    return TRUE;
}


Til at kalde det her skidt med har jeg den følgende exe fil :

//------------------------------------------
//EXE Fil
//------------------------------------------


#include <windows.h>

typedef int (CALLBACK* LaunchSplashScreenProc)(HINSTANCE);

MSG  Msg;


int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,  LPSTR lpCmdLine, int nCmdShow)
{
  HMODULE DllHandle = LoadLibrary(\"SplashScreen.dll\");
  LaunchSplashScreenProc LaunchSplashScreen= (LaunchSplashScreenProc)GetProcAddress(DllHandle,\"_LaunchSplashScreen\");
  LaunchSplashScreen(hInstance);
  FreeLibrary(DllHandle);

  return 0;
}

problemet er når jeg lokker min Spash Screen, enten ved at dende en WM_DESTROY efter den eller ved at trykke ALT + F4 så dør det hele.

Jeg vil gerne vide hvad jeg gørgalt siden jeg ikke kan lukke den igen.
