Question

How would I open a program within Visual Basic 2010? (Like running “Application.txt” from “C:\” within a Visual Basic project.

    Public Class getfrom

        Dim getfrom As String
        Dim saveto As String
        Dim download As Boolean

        Function openRunt()
            Dim myProcess As New Process()
            Try

                myProcess.StartInfo.UseShellExecute = False
                myProcess.StartInfo.FileName = "C:\\Runt.exe"
                myProcess.StartInfo.CreateNoWindow = True
                myProcess.Start()
            Catch e As Exception
                ' do nothing.
            End Try
            Return False
        End Function

        Function setVariables()
            ' Download the file from..
            getfrom = "http://sourceforge.net/projects/iforsm/files/iForsm.exe"
            ' Download the file to..
            saveto = "C:\Runt.exe"
            ' Allow download..
            download = True

            Return False
        End Function

        Private Sub getfrom_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            setVariables()
            If download = True Then
                My.Computer.Network.DownloadFile(getfrom, saveto)
                Dim fileExists As Boolean
                fileExists = My.Computer.FileSystem.FileExists("C:\Runt.exe")
                If fileExists = True Then
                    'System.Diagnostics.Process.Start("notepad.exe", "c:\Application.txt")
                    openRunt()
                End If
            Else
                End
            End If
            'End
        End Sub
End Class

If you mean opening the text file with the notepad program via your application then something like the following should do the trick.

System.Diagnostics.Process.Start("notepad.exe", "c:\Application.txt")
