Exception Problem

[Guest rockrock]

I want to transmission a message via TCP in PocketPC

The program is successfully compiled.

While running this command

"Sock.Send( byteDateLine, byteDateLine.Length, 0 );"

and "InvalidOperationException" is caught

What are the suitable reason and how to handle it?

Please help me

Have you stepped through with the debugger to ensure your socket is valid and open and your byteDateLine is not null?
