Launching an external EXE and Hiding a button

I am pretty new to Visual Basic and I started working with .NET 2005 Express Edition and found that for such a program to run the system must have .NET FW 2.0 installed on it. My application may not necessarily be run on a system that already has FW 2.0 installed on it, so my option is to use VB6, thus eliminating the dependancy on any FW version being installed. This is just a simple program that will be placed on a DVD and autorun when the DVD is inserted in the ODD. This program should launch, determine which buttons to display and based on what button the user clicks what it should do. There is a Cancel Button on it that I have already figured out how to code, but I am running in to problems with the buttons that will launch a seperate progam when clicked, and with determinaning what buttons should be displayed when the program runs. Below is the code that I was able to successfully create that requires FW 2.0 to be installed. I would like to know if anyone knows what changes it takes to port this back to VB6?

Upon loading the form I need it to check if the OS is VISTA and if so it needs to hide Button2. I have the form created with all the buttons, I just need the correct code for the buttons and the form load.

Any assistance would be greatly appreciated.

Code:

---

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.Close()
        Dim a As New ProcessStartInfo("APP1\setup.exe")
        Process.Start(a)
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Me.Close()
        Dim a As New ProcessStartInfo("APP2\setup.exe")
        Process.Start(a)
    End Sub

    Private Sub Cancel_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Cancel_Button.Click
        Me.Close()
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If ((System.Environment.OSVersion.Platform = PlatformID.Win32NT) AndAlso (System.Environment.OSVersion.Version.Major = 6)) Then
            'Vista
            Me.Button1.Visible = False
        End If
    End Sub
End Class

Welcome to VBForums :wave:

First of all.. while VB6 has smaller installation requirements than VB.Net, it still has some - so your program will not work unless somebody else has already installed the files you need. If you are making a very simple program (no extra components or references) then the files you need may be installed already as part of Windows (they are for Vista, there is some debate about XP & 2000, and they are not included before that).

To run a separate program you can simply use Shell, eg:

Code:

---

Shell "d:\folder\program.exe"

I'm afraid I haven't got a link to code to detect Vista, but there is some around on the forums so a search should find it!

Here is code to determine the OS version in VB6:

http://vbnet.mvps.org/index.html?cod...winversion.htm

I have seen that vbnet code example already and its pre release code. Since the final release of Vista my code will work more accurately with it. Also, detects the version of Vista correctly instead of saying "Vista Plus".

Its .NET but the eval code is practically the same as VB 6. ;)
