'Or' and 'And' do not skip - everything is evaluated.
'OrElse' and 'AndAlso' only evaluate until the result can be determined - 'OrElse' stops evaluating on the first 'True' and 'AndAlso' stops evaluating on the first 'False'.
VB.Net does not support "short circuit boolean evaluation" which just means that even if your first expression is false with an AND, it still evaluates the second expression.
Short circuit boolean evaluation can be achieved in VB.NET using the AndAlso or OrElse logical operators
You need to use the following code to accomplish what you are trying to do:
If condition1 = False AndAlso condition2 = False Then
End If
