VB.Net-FORM - Opposite of 'Is Nothing'

[abev]

I am checking to see if a form is already set to an instance but I have only been able to do this backwards. What is the opposite of this statement?

 
 'Hide IO form
If Main.myinsertorder Is Nothing OrElse Main.myinsertorder.IsDisposed Then
 
Else
     Main.myinsertorder.Hide()
End If

Why? It's doing exactly what you want?
The opposite of nothing is anything.
That would be a LOT of if statements if you wanted to check if it was ANYTHING.

It is doing exactly want I want Plater, thanks.

My only concern was I thought it was bad practice to have a statement where the 'true' portion of the IF statement was empty?

Check this

Not (Main.myinsertorder Is Nothing)

Check this

Not (Main.myinsertorder Is Nothing)

Indeed. It's all in how you arrange it.

Checking for null (Nothing in VB) is a pretty vital part of an error free application, so it's good that you're doing it.
