launch a web browser from windows application form

[vinteron]

I'm a new programmer and am trying to launch a web browser from a windows application form. When running the code below I get an error message file not found message. Does anyone know why and how to fix this?
___________________________________________________
Private Sub OpenURL(ByVal URL As String)

System.Diagnostics.Process.Start("cmd/c ""start

http://www.google.com""")

End Sub

Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
Dim url As String

Call OpenURL(URL)

_________________________________________________________

An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in system.dll

Additional information: The system cannot find the file specified

A couple of points:

Your format for Process.Start with a Command Tail is wrong see below.

You do not use the URL parameter in the Sub OpenURL.


This is your code modified to work.

  Private Sub OpenURL(ByVal URL As String)

    System.Diagnostics.Process.Start([b]"cmd", "/c start [URL unfurl="true"]http://www.google.com"""[/URL][/b])

  End Sub


  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim URL As String
    OpenURL(url)

  End Sub

This version uses the URL parameter - the button click could perhaps pick up the URL from an InputBox or other UI element.

  Private Sub OpenURL(ByVal URL As String)

    System.Diagnostics.Process.Start("cmd", "/c start " + URL)

  End Sub


  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim URL As String = "[URL unfurl="true"]http://www.google.com"[/URL]
    OpenURL(URL)

  End Sub

Hope this helps.
