I have the following 2 examples, I want to figure out a way that I can do a check on anything in VB.NET, I thought there would be a function IsExists but I can't seem to find one.
#1, I want to check if this dataset has a table named "testing".
#2, I have a MS Chart and want to check if it already has a series called "testing"
I tried to do..
If Not Chart1.Series("testing") Is Nothing Then
' code here
End If
But that does not work, it throws an exception.
...
Go to the complete details ...
