DirListBox control in vb.net2005

[hrishi321]

hi to all Could anyone please tell me how to block certain drives to be accessed while looking for sub directories and files. (All I want is to give an environment to the user so that HE CAN LOOK FOR FILES IN A DIRECORY, WHICH ALSO MAY HAVE SUBDIRECTORIES). The tool I am using is dirListBox in vb.net2005. But my problem is that user can go to all the files and directories in the computer. (i WANT HIIM TO ACCESS THE FILES AND FOLDER OF A SPECIFIED DIRECTORY ONLY, SAY INSIDE C:\AA).. NOW HOW TO FILTER THE DIRLISTBOX,? please advice me if any other method is there for the same...(not necessary to be the DirListBox control) THNAKS IN ADVANCE

There is no "DirListBox" in VB.NET. Are you talking about the OpenFileDialog or are you using the old DirListBox from the VB6 days?? The old DirListBox could not be filtered or limited to a group of folders.

Have a read through the members of OpenFileDialog, in the MSDN documentation. It should be fairly easy to find the correct solution.

The OpenFileDialog class is a wrapper to call the Win32 function OpenFile (? I can't remember which the function name exactly!). Win32 displays the dialog, not the .NET class OpenFileDialog. OpenFileDialog is also a sealed (NotInheritable) class, so you can't really modify it at all. You can't even get the window handle to the dialog and start throwing messages at it since your code stops running when you call the dialogs .ShowDialog method. Your going to have to write your own dialog to support this. It would just be a simple Form with a TreeView for a directory browser, and a ListView for files in the currently selected directory. Oh, and of course, a couple of buttons for Open and Cancel.
