Question

Visual Basic - How do I start another program within my code?

Asked by: rpacint

I am very new to writing Visual Basic and trying my best. I've gotten pretty much everything to work the way that I want it except this one line:

System.Diagnostics.Process.Start("c:\NK2View\nk2view.exe /delete_contains", NK2toDelete)

In short, I'm trying to call a another program that uses the quotes characters as part of the argument to start the program. Obviously VB doesn't like this. I've tried several different methods of using Chr(34), the & and variables and cant get it to work. this last version below I am trying to use variables but cant get it to work either.

The exact command line I want to execute is:

C:\NK2View\nk2view.exe /delete_contains "@emaildomain.com"

I guess I need help on System.Diagnostics.Process.Start object.

Any suggestions greatly appreciated.

Thanks!!

Imports System
Imports System.IO
 
Module Module1
 
    Sub Main()
 
        Dim NK2ViewPath, NK2Dir, fileEnding, NK2FileBackup, Complete As String
        Dim NK2Files
 
        NK2ViewPath = Environ("SystemDrive") & "\NK2View\"
        NK2Dir = Environ$("USERPROFILE") & "\Application Data\Microsoft\Outlook\"
        NK2Files = Directory.GetFiles(NK2Dir, "*.NK2")
        fileEnding = "_" & Replace(DateValue(Now), "/", "-") & "_" & Replace(FormatDateTime(Now, DateFormat.ShortTime), ":", "_")
        Complete = "Complete.txt"
 
        If Not System.IO.File.Exists(NK2Dir & Complete) Then
            If Not Directory.Exists(NK2ViewPath) Then
                My.Computer.FileSystem.CopyDirectory(Environ$("LOGONSERVER") & "\NetLogon\NK2View", NK2ViewPath, True)
            End If
            Dim NK2toDelete
            NK2toDelete = Chr(34) & "@emaildomain.com" & Chr(34)
            'Console.WriteLine(NK2toDelete)
            For Each NK2File In NK2Files
                NK2FileBackup = (NK2File) & (fileEnding)
                System.IO.File.Copy(NK2File, NK2FileBackup)
                System.Diagnostics.Process.Start("c:\NK2View\nk2view.exe /delete_contains", NK2toDelete)
            Next
 
            System.IO.File.Create(NK2Dir & Complete)
 
        End If
 
    End Sub
 
End Module
