Gentlemen,
I have found a very nice tooltip control on the following link
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=6967&lngWId=10

I tried to convert it to vb.net , and the solution works , but with some error . I beleive it is related to the namespace issue. Please check attached file for the C# source code and the vb.net source code.

I appreciate your support to define why I am getting these error , and how to solve (guidelines).

Thanks so much .
Waleed
