Don't know if this will work or not, but have you tried just using CBitmap
objects and calling the LoadBitmap function with the resource ID rather than
the FromHandle() stuff. I only use FromHandle if I need to load a bitmap
from a file, but it looks like you are using built in resources.

Also, can't tell from the code, but are you sure there is an image in the
mImageList?

This discussion (with code in the discussion) may be interesting to you:

sorry - this is the code:

void CMyButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct) //
Drawitem of an owner-drawn button
{
CDC *pDC = CDC::FromHandle(lpDrawItemStruct->hDC);

//Drawing the Bitmap
IMAGEINFO stII;
mImageList.GetImageInfo(0, &stII);// mImageList is a CImageList
CRect rcBM (stII.rcImage);

HBITMAP hbmTest = ::LoadBitmap(0, (LPCTSTR) IDB_TESTPICTURE);

CDC cDCTemp;
cDCTemp.CreateCompatibleDC(pDC);

CBitmap *pBMResult =
cDCTemp.SelectObject (CBitmap::FromHandle(stII.hbmImage)); // fails
pBMResult =
cDCTemp.SelectObject (CBitmap::FromHandle(hbmTest)); // succeeds

BOOL bOK = ::StretchBlt(*pDC, 0, 0, 30, 30, cDCTemp, 0, 0,
100, 100, SRCCOPY); // this shall be done
