VB 5 Keeps crashing on me!

[kl899]

Hello. I'm using vb5 professional edition and whenever my program terminates, the entire vb design environment terminates with it! No errors are being generated within my program. It's is accessing a DLL. Here is the code:

Option Explicit

Dim session As Object

Private Sub cmdLogon_Click()

On Error GoTo logon_error
If txtServer.Text = "" Or txtUser.Text = "" Or txtPass.Text = "" Then
MsgBox "Please input server, user and password."
Else
session.CTLogon txtServer.Text, txtUser.Text, txtPass.Text
End If

Exit Sub
logon_error:
MsgBox "Error # " & CStr(Err.Number) & " " & Err.Description
Err.Clear
Exit Sub
End Sub

Private Sub Form_Load()
Set session = CreateObject("CTI.Session.1")
End Sub

Private Sub form_terminate()
Set session = Nothing
End Sub

I don't know about VB5, but I've found that in VB6, inside the Terminate event, the form has already been destroyed, along with the object representing it.

Private Sub form_terminate()
Set session = Nothing
End Sub

Therefore, when your form_terminate() is called, there is no form anymore. At this point, 'session' is not accessible. In VB6, as soon as you refer to Session, a new copy of the form is automatically created and its Session variable is set to Nothing. My guess is that in VB5, the new form is NOT created and the Session reference therefore crashes VB.

Solution: Never use Form_Terminate(). Do all your unload processing in Form_Unload.

That didn't solve my problem. Even if I set session = nothing before the form unloads, all of vb blows up.
