Display Directory Structure using TreeView in VB.NET

Today in VB.NET, i will teach you on how to create a program that loads and displays the directory structure of C using the TreeView control in VB.NET. So, now let's start this tutorial! 1. Let's start with creating a Windows Form Application in Visual Basic for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Next, add only one TreeView1 named TreeView11 to display the contents of C directory structure. You must design your interface like this: 3. Add Imports System.IO to the topmost part of the code tab because we will access the directory. 4. Create a method named PopulateTreeView with directoryValue As String and parentNode As TreeNode as parameters. On this, create a try and catch method. In the try method, create an array variable (string) named directoryArray that holds and gets the directory either C or D. Now, create an If statement that if your computer has obtained a directory this will add all the directory folders to the treeview using For Next Loop. In the catch method, put this code below to handle UnauthorizedAccessException and will prompt the user "Access Denied". 5. Add this code for the form_load of your program. This will load the C directory structure using the PopulateTreeView method that we have created above. Full source code: Output: Download the source code below and try it! :) Best Regards, Engr.
