Birdman - Here is one way or you could use ShellExecute as mentioned in that other post.
Filestring = "notepad.exe " & myfile
Response = MsgBox("Data File Created" & Chr$(13) & Chr$(10) & _
"File = " & myfile & Chr$(13) & Chr$(10) & _
"Would you like to edit the file now?", vbYesNo, "ABC, Inc.")
If Response = vbYes Then
RunIt = Shell(Filestring, 1)
myfile would = "C:\Program Files\Process Files\Help File.txt" in your case.
OR you could just put the text of what you want to show in a textbox of a userform, so that when they click the button, it will display the info. Put an OK button on the form to enable them to close it. That would make it uneditable but also allow them to see the "readme" info.
