Winsock, send command

Hi again peeps,

I have an 'Client/server', and i can connect to that Listning server with my client, but that's all :)

How do i have to modify the 'server', to execute an 'command' on it? So, that if i hit command1 on the client, that the server shows an msgbox?

i thought it was something with:

VB Code:

Case 1
msgbox ("Yahoo! it works", vbOkOnly, "Info")
Case 2
end

But how dus this Case work? and how do i call it in my client, to execute it on the server thru winsock?
