Wow, that was the most helpful doc I've read all day! Thanks!
The article states that if you want windows to be able to extract
thumbnails of your documents, you need to create a "thumbnail
extractor" COM object. Now I understand that I can create an
OLEobject to wrap around the COM (which i need to find out from the
vendor what the identifier is)
Now on to the next question...Am I going to be able to implement
these methods using RB?
STDMETHOD (GetLocation) (
LPWSTR pszPathBuffer,
DWORD cchMax,
DWORD *pdwPriority,
const SIZE *prgSize,
DWORD dwRecClrDepth,
DWORD *pdwFlags);
STDMETHOD (Extract) (HBITMAP *);
HRESULT CMyExtractor::Extract(HBITMAP* phThumbnail)
{
HICON hi = ExtractIcon(NULL, m_szFile, 0);
ICONINFO ii;
GetIconInfo(hi, &ii);
*phThumbnail = ii.hbmColor;
DestroyIcon(hi);
return NOERROR;
}
Or am I going to need to create my own DLL wrapper. Sorry for the
basic questions, but I am TOTALLY LOST!

look for IExtractImage --- I have doubts about RB and COM -- too
much windows knowledge needed, but maybe someone from ?? knows.

Subject: Reading Explorer Shell Thumbnails

I am working with another vendor to be able to read thumbnails of his
files as pictures into my application. They said they are using a
"standard explorer shell method" for generating thumbnails in
windows. Anyone know if I can tap into this in Windows to get the
information I need?
