Using Windows Explorer Shell in a Dialog Com Control
Keywords: ShellFolderView Object Windows Explorer Shell in a Dialog COM Control COMCONTROL Explore Browse Thumbnail
Question:
I have to sort my slides, which are scanned. I want to select a jpg-file in a windows-dialog, which shows thumbnails.Answer:
The trick is to pass the file path to a COMCONTROL in a dialog. then capture the selected file name in a Dialog Callback procedure. objFolderItem = oShell.Document.FocusedItem returns a Folder object then use the name property to grab the selected file name.reference: http://msdn.microsoft.com/en-us/library/bb774049(VS.85).aspx
