Double-click a folder browser dialog?

[David Veeneman]

I'm trying to implement some fairly standard behavior (or so I thought) on a
FolderBrowserDialog component. double-clicking a folder in the dialog should
have the same effect as selecting the folder and clicking the dialog's OK
button. But the FolderBrowserDialog component doesn't implement that
behavior, and it doesn't have a double-click event that would allow me to
implement it.

Is there a simple way to implement this behavior? Thanks.

David,

Unfortunately, this isn't made available to you. It's not even
available through the API call SHBrowseForFolder (which is what the
FolderBrowserDialog calls, ultimately). You could try and derive from
FolderBrowserDialog, and replace the hook procedure (HookProc) as well as
the RunDialog procedure and then get the window handle for the tree view,
but that's VERY implementation specific, and I wouldn't depend on it.

Unfortunatelly that feature is not available, not only that but
FolderBrowserDialog is a sealed class, so you cannot inherit from it.

You either implement your own FolderBrowserDialog from the scratch or look
around for a third party implementation

Yep, it says so in the MSDN:

That sucks. In that case, the OP should extend CommonDialog and call
SHBrowseForFolder, and try to find the tree view window, or like you said,
get a third party implementation.
