Item does not exist GetOpenFolderItem

Why am getting a “This item does not exist” on GetOpenFolderItem? This happens in a Web Application.

Dim f As FolderItem f = GetOpenFolderItem("text/plain")

Don’t think its supported on web:

Doh!! Gotta use the WebFileUploader.

Is there a way to have an “Open” dialog on a client side (much similar to what “WebUploader” does).

Only with WebFileUploader. That’s a function of the browser itself.
