Transparent Splash Window

Environment: VC6 Windows98/NT/2000

Do you want to cool splash window?. The general splash window is not good for your app??
This sample source is for you.
My semi-transparent splash window use 'AlphaBlend' function.
When I found this function, I was so surprised!!
Here is 'AlphaBlend' function's feature.
BOOL AlphaBlend( HDC hdcDest,
  int nXOriginDest,
  int nYOriginDest,
  int nWidthDest,
  int nHeightDest,
  HDC hdcSrc,
  int nXOriginSrc,
  int nYOriginSrc,
  int nWidthSrc,
  int nHeightSrc,
  BLENDFUNCTION blendFunction
);
The important parameter is last one,BLENDFUNCTION.
typedef struct _BLENDFUNCTION {
    BYTE     BlendOp;
    BYTE     BlendFlags;
    BYTE     SourceConstantAlpha;
    BYTE     AlphaFormat;
}BLENDFUNCTION, *PBLENDFUNCTION, *LPBLENDFUNCTION;
We use 'SourceConstantAlpha' value. You can set this value between 0(transparent) and 255(semi-transparent).

    FYI,

    Code works under NT but it's necessary to
    put Msimg32.dll somewhere MSDEV can get it. But it works a little bit strange even I can say jerky - maybe it's due to weak hardware or this is software bug? Have you ever seen something like that?
