I have successfully solved it just by getting my hands dirty with .Net syntax. Actually, I do not work with .Net and I am not even a Computer Programmer, So, when I stuck at a point, without thinking for a while i just posted this question, but after that I kept on trying, and here's the result. I wasn't that difficult.
Here is my so simple solution to it, please tell me about the correctness of this code.
Public Sub btnClose_MouseUp(sender As Object, e As EventArgs) Handles btnClose.MouseUp
I am not hundred percent sure that it is correct, but as per now, it's working successfully.
Thank you for your time.
