Converting a CPicture to a CBitmap

Posted on 1998-05-20

I am retreiving a CPicture from an OCX control.  I need to turn it into a CBitmap and I am having problems.  I use CBitmap::FromHandle(HANDLE) using the CPicture::GetHandle(), but the header is corrupted and the image is off by several bytes.

Try this.

LPPICTURE lpPicture;
CBitmap bm;
if(SUCEEDED(m_lpDispatch->QueryInterface(IID_IPicture, (LPVOID *)&lpPicture)))
lpPicture->get_Handle((OLE_HANDLE *)&hbm);
