Uh... Are you asking a question or is this like a tutorial? If it is a question, please use the "How do I confirm" or "How is an array confirmed" form, or simply add a question mark. I'm not trying to mock you...

If the array is completely empty and thus null, you could just use the IsNull function, like so or IsEmpty(): If Isnull(array) then msgbox "array is empty" or If IsEmpty(array) then msgbox "array is empty"

Didn't really see if you were talking VB 6 or .NET. In .NET you can use the "Nothing" keyword. Dim array() As Integer If array Is Nothing Then 'do something End If

Visual Basic: Unload Your Application Correctly!
(1) What many of us do not know is that using a button on a form with the function "Unload Form1" or

running, or just give you unwanted errors by exiting improperly. All you need to do is unload all
components, forms, controls, etc. upon unloading. Say you have 2 forms in your project, 1
component, and 2 controls. If these ojects are placed onto a form, unload them properly!....
