In VB.NET, when you use shell or have a process object point to and run a
separate application that is installed on the machine, is there a way of
determining the path to the executable? I've been having the user point to
it using the Open File Dialog from an Options menu item, but the program
should be able to determine the path to a named program without relying on
user intervention.

Thanks.

Don't know if this is the best way, but you can just loop through the paths
in the PATH environment variable and look for the file in each one. Here's
a console app that does it:

Imports System.Environment
Imports System.IO

Module Module1

Sub Main()
Dim fileToFind As String = "Notepad.exe"
For Each pathName As String In
GetEnvironmentVariable("path").Split(";")
Dim fullPath As String = pathName & "\" & fileToFind
If File.Exists(fullPath) Then
Console.WriteLine(fullPath)
End If
Next

End Sub

End Module
