In a VB.NET Windows Forms application how do I add the capability for someone to click a button or image and open a file browser to browse to a file and assign it's path to a variable so I can copy that file to another specific path?

The OpenFileDialog control prompts the user to open a file and allows the user to select a file to open. The user can check if the file exists and then open it. The OpenFileDialog control class inherits from the abstract class FileDialog.
OpenFileDialog component opens the Windows dialog box for browsing and selecting files. To open and read the selected files, you can use the OpenFileDialog. OpenFile method, or create an instance of the System.
The Open dialog box lets the user specify the drive, directory, and the name of a file or set of files to open. You create and display an Open dialog box by initializing an OPENFILENAME structure and passing the structure to the GetOpenFileName function.
You should use the OpenFileDialog class like this
Dim fd As OpenFileDialog = New OpenFileDialog() Dim strFileName As String fd.Title = "Open File Dialog" fd.InitialDirectory = "C:\" fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*" fd.FilterIndex = 2 fd.RestoreDirectory = True If fd.ShowDialog() = DialogResult.OK Then strFileName = fd.FileName End If Then you can use the File class.
