VB.NET retains compatability with VB6 when using AND in a conditional - it attempts to evaluate all of the expressions. For short-circuit conditional expression evaluation, use AndAlso.

P.S. The Val() in Val(CDbl(txtCost.Text)) is not necessary.

>Hi all,
> How does IF condition works with AND clause? I have 2 conditions here. Please look for the below code. FYI, when the control reaches here, the value of txtCost.text = "". Here the system is checking for second condition also, when the first condition itself fails. The same kind of code does not execute the second condition in VFP, when the first fails. Why should .Net execute the second condition? Any idea?
