inet question.

Alright, a friend of mine told me an easy way to check if a url is valid is just to send it to inet, and set the timeout to four.
If inet times out then the website doesn't exist.

How on earth do I do this using VB6?

If it returns nothing it isn't online or doesn't exist.
Use the Microsoft Internet Transfer Control

VB Code:

Private Sub Form_Load()
  Text2.Text = Inet1.OpenURL("http://members.aol.com/dandono/180205.txt", icString)
End Sub
 
Private Sub Text1_Change()
If InStr(1, Text1.Text, ",") = 0 Then
    If InStr(1, Text2.Text, Text1.Text) = 0 Then MsgBox "Activation code not found" Else MsgBox "Program activated successfully", vbExclamation
Else: MsgBox "Illegal characters"
    End If
End Sub

This grabs a text file from a site, and finds a code to activate an app. You can just download the text of the site.
