Problem with Drag file from application to Windows Explorer

MFC

Hi,

I have an application using IStream and IStorage. It has a list from where I am trying to implement drag-drop operation to and fro w.r.t. Windows Explorer. I am having problems dragging the file from the application to the PC.

When I do the drag, I am getting a progress bar but that is about it. It doesn't complete the transfer. Infact, even on pressing "cancel", the progress bar doesn't go. I would have to restart the explorer.

I don't know what more details to put up here for this problem. It is using COleDataObject. The formats used are CFSTR_FILECONTENTS, CFSTR_FILEDESCRIPTOR... I am not a pro in this and MSDN documentation simply is useless. Not finding anything useful. :(

Please let me know if any other details are needed..
