Hi,

I'm new to programming with visual basic.
I used Access before.

In acces the code to test for empty or null string should be:

If me.txtName = "" or me.txtName is Null then

But this gives an error in VB Express 2008.
What is the code to use to be able to check this?

Thanks

Null is Nothing in VB.NET:

If Me.txtName = "" or Me.txtName Is Nothing then

However, an easier and preferred method is IsNullOrEmpty on the string class:

If Not String.IsNullOrEmpty(txtName) Then

End If

If txtName is a control rather than a string, you need to use its Text property:

If Not String.IsNullOrEmpty(txtName.Text) Then

End If

Hope this helps,

Imar
