Why would StreamReader or StreamWriter open Notepad

[DVader]

Okay, we've run across something a bit odd. I have a Windows forms application, that when it starts, downloads and opens a file (with a .ini file extension) to retrieve some system settings.

 

   Private Sub SetupKioskInformation()

       Dim strKioskString As String = ""
       Dim strProperty() As String = Nothing
       Dim strObject As String = ""
       Dim strValue As String = ""
       Dim bolbtnWebpageOneSet As Boolean = False
       Dim bolbtnWebpageTwoSet As Boolean = False

       Try
           '--------------------------------------------------------
           '-  Determine if the Kiosk.ini file exists . . .
           '--------------------------------------------------------
           If File.Exists(strApplicationPath & "kiosk.ini") = True Then
               '----------------------------------------------------
               '- If it does open it in a StreamReader . . .
               '----------------------------------------------------
               srStreamReader = New StreamReader(strApplicationPath & "kiosk.ini")

               Do While srStreamReader.Peek >= 0
                   '-  Do some stuff . . . 
               Loop
       Catch ex As Exception
           WriteToErrorReport(ex.Message,  ex.StackTrace, "SetupInformationButtons")
       Finally
           If srStreamReader IsNot Nothing Then
               srStreamReader.Close()
               srStreamReader.Dispose()
           End If
       End Try

   End Sub

 

And it also opens another file to write some log information to. This file has a .log extension.

 

   Private Function WriteLastTransferDate() As Boolean

       Dim bolWriteLastTransferDate As Boolean = True

       Try
           swStreamWriter = New StreamWriter(strApplicationPath & strLastTransferDateFileName, False)
           swStreamWriter.WriteLine(Now.ToShortDateString)
       Catch ex As Exception
           bolWriteLastTransferDate = False
           WriteToErrorReport(ex.Message, ex.StackTrace, "WriteLastTransferDate")
       Finally
           If swStreamWriter IsNot Nothing Then
               swStreamWriter.Close()
               swStreamWriter.Dispose()
           End If
       End Try

       Return bolWriteLastTransferDate

   End Function

 

This application is running on Windows 7 32-bit version. On two of the three machines it is installed on everything works fine. But on the third machine, for some reason, when we minimize or close the application we see each of the above mentioned files open in Notepad.

 

The question I have is why should Notepad be opening for either of those files since I'm not using Notepad?

Is there any different software installed on this third machine? What happens if you you use another application to create a file with the same name as one of the above files?

[DVader]

No, as far as I know, they should be identical machines.

I can't see any reason from the code posted why this should happen, if you step through the code can you spot which line is executed before notepad opens?
