FolderBrowserDialog - network access

Question

Hi, I am using a FolderBrowserDialog to allow the user to select a folder. This nicely allows the user to select network folders, and even provides a popup in case a username and password are required. 

When the FolderBrowserDialog returns, it has the selected-folder which my program can access.

Is it possible for my program to obtain any username and password the user may have entered?

Thanks.
