           Summary: OleLoadPicturePath loads image in windows but not in
                    wine, could cause access violation in some circumstances
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: support at robertinventor.com


Created an attachment (id=15202)
 --> (http://bugs.winehq.org/attachment.cgi?id=15202)
source code for program to duplicate the bug

This code works in Windows but not in Wine - running under KDE 

WCHAR wpath[MAX_PATH];
MultiByteToWideChar(CP_ACP, 0, pszPath, -1, wpath, MAX_PATH);
IPicture* pPic=NULL;
CoInitialize(NULL);// NOT NEEDED IN WINDOWS
// INCLUDED JUST IN CASE IT IS NEEDED FOR WINE but doesn't fix it.
OleLoadPicturePath(wpath, NULL, NULL, NULL, IID_IPicture,(LPVOID*)&pPic);
...

In case where the file does exist, OleLoadPicturePath isn't initialising pPic.

If the app tests for file existence first, and doesn't initialise pPic, the
result could be an access violation.

(I'm using the VMWare MultiBrowser Appliance as a way to run Linux on my Vista
machine.)

Source code for app attached, obviously replace the example pictures with
existing files on your machine.

Hope this helps. The reason my app calls OleLoadPicturePath(..) instead of
LoadImage(..) is because it is an easy way to add the capability to load jpegs
and gifs without need to add extra image libraries (which would add to the size
of the installer).

Not that important for my program, just means the users would have to convert
the skin images to bitmaps in order to use them. But maybe it might affect
other programs too, and could cause an access violation if the programmer
doesn't initilise the pPic.

Hope this helps, any questions?

Robert
