Search through a directory.

[TheDarklord]

I have a sample which I rewrote so that it will only search for mp3 extension files.

It allows the user to select a drive and then one folder.

What would be the best to edit it so that it allows the user to search through a specific directory path?

            {
                cmbDrives.Items.Add(strDrives[i]);

Use the FolderBrowserDialog class.

Use the FolderBrowserDialog class.

How do I use this?

Do I just change parts of the code, like for "openMenuItem_Click" to "button1_Click" and others?

Or those this have to be a separate file?

[BigEd781]

Well, I am sure that the documentation would help you out if you did a bit of searching. It is just a simple dialog form that allows the user to search for a directory. When they are done you can use a property of the dialog to get the path as a string.
