I am new to .Net, so apologies if this is a simple question. I need a way of display folders and files to my users. However, it must show whether they have NTFS access to the file/folder. For example, if they have access the folder or file is displayed as a link, if they dont it is displayed only as text. Is this possible? Any help would be greatly appreciated.

I have an aspx page that does not have a separate source for the VB - it is on top in between the <script> tags. I use the following statement Dim oComLib as New ComLib To reference a class called ComLib in a source member called ComLib.vb that is found in the /Code folder of my project. It all works fine in the VWD2005 environment as when I run the aspx page, it processes the above statment and "sees" the class reference in the code.
