when i tried to debug or upload the project in "visual studio 2005" in the "C#" language.
this problem view to me :-
No value given for one or more required parameters.

i need a help plz quickly
i will be thankful to any answer.

I haven't ever touched c#, but sounds like you tried to use a function who neede several parameters, and forgot some...

C# rocks.

The problem is in the query being sent from the C# .net code to the database. I told you how to debug this in the ASP forum, where you posted the code. Go have a look there.
