Does this help?
http://www.velocityreviews.com/forums/t20619-restrict-the-user-to-a-particular-folder-in-openfiledialog-control.htmlWhat kind of problems do you have?
>Anyone done a custom openfiledialog in C# (winform)? I need to create a list of all .wav files in a specific directory (that I will set behind the scenes) and allow the user to choose one file from the list. After the user selects a file from the list, I will store the value (filename) in a textbox on a form. It's basically replacing the standard openfiledialog. I don't want the user to be able to manuever around the directory structure or path (no browsing) or have any of the buttons on the default dialog available. I cannot control the existing openfiledialog to that extent. Seems simple enough, but I keep running into problems.
