 Hi,
 
Here is my problem, when I use SetIcon() in this way, it works fine,
 
 
CXTPTaskPanelGroupItem *pItem;
CXTPImageManagerIconHandle hicon( AfxGetApp()->LoadIcon(IDI_ICON) );
m_TaskPanel.GetImageManager()->SetIcon( hicon, pItem->GetID() );
 
 
But in this way, it won't display the icon,
 
 
CXTPTaskPanelGroupItem *pItem;
HICON hicon = AfxGetApp()->LoadIcon(IDI_VEC);
HBITMAP hbmp = MyFunction( hicon );
CXTPImageManagerIconHandle xtpicon( hbmp );
m_TaskPanel.GetImageManager()->SetIcon( xtpicon, pItem->GetID() );
 
 
And I chased the source code,
 
 
CXTPImageManagerIcon::PreMultiplyAlphaBitmap()
{
   TRY
   {
      hBitmapAlpha = CreateDIBSection(dcSrc, pBitmapInfo, DIB_RGB_COLORS, (void**)&pDest, NULL, 0);
   }
}
 
I use CDC.BitBlt() to see the hBitmapAlpha, it's totally black.
 
Did I miss something ??  Please help me.
 
 
 Happy Chinese New Year !!

Hi,
If yo use CXTPImageManagerIconHandle xtpicon( hbmp ); ImageManager assumes that hbmp  is 32bit alpha bitmap.
