Edited 5 Years Ago by peter_budo: Keep It Clear - Do use code tags when posting any code

Sorry friend, we don't provide ready made code here. I believe I've pointed you in the correct direction. Do your part and post again if you are facing problems.

PS: Even if I wanted I couldn't help as your code is in C# and I only know VB
PS2: If you are having problems post in the C# section.
