LoadImageFromResource
This function can load any kind of image from the resource of an executable or dll using COM interfaces.
HBITMAP LoadImageFromResource(UINT resId, LPTSTR resType)
{
HBITMAP bitmap = NULL;
HRSRC resHandle = FindResource(NULL, MAKEINTRESOURCE(resId), resType);
if (resHandle)
{
HGLOBAL memData = LoadResource(NULL, resHandle);
if (memData)
{
DWORD resSize = SizeofResource(NULL, resHandle);
HGLOBAL globalData = GlobalAlloc(0, resSize);
LPVOID lockedData = GlobalLock(globalData);
memcpy(lockedData, memData, resSize);
GlobalUnlock(globalData);
LPSTREAM pStream = NULL;
CreateStreamOnHGlobal(globalData, FALSE, &pStream);
LPPICTURE pPicture = NULL;
OleLoadPicture(pStream, resSize, TRUE, IID_IPicture, (LPVOID*)&pPicture);
if (pPicture)
{
HBITMAP handle = NULL;
pPicture->get_Handle((unsigned int*)&handle);
bitmap = (HBITMAP)CopyImage(handle, IMAGE_BITMAP, 0, 0, LR_COPYRETURNORG);
pPicture->Release();
}
pStream->Release();
GlobalFree(globalData);
}
}
return bitmap;

I should like to draw description an error in your function.
Unfortunately failed me to load a portable network graphics file.
This also move a description of Microsoft only with the GDI+ class!
This is probably due to the free ZIP algorithm?
Or wrong I something? Sorry my English!
