Question

In VB.net, how can you programmatically launch a .exe file? Is there a way to check if the file is there?

I know there is some way to check using System.IO, but I have no idea. However, I have not even the slightest clue as to how to launch that .exe if it is there, so thanks for the help!

Use System.IO.File.Exists and System.Diagnostics.Process.Start.

        Dim someExe As String = "MyAppsPath\some.exe"
        Dim fullPath As String = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles), someExe)
        If File.Exists(fullPath) Then    'Checks for the existence of the file
            Process.Start(fullPath)      'Executes it
        End If
