TCP Commands

Well, i've got my client and server running, but im not sure how to send commands. I know to use the SendData or whatever but how would i send a command so that the other one executes a function upon recieving it?

Ok,

Step back and look at whats going on. To make a function execute on the client side (for example) there is no set method more your going to have to work out some programming logic and set somthing up yourself. A commonly used method involves creating 'symbols' for functions eg

We are going to send a command which issues a function of the client that pops a messagebox with the text we send. So!

From the server you will need to send the command and the text!

VB Code:

dim iText as string
 
iText = inputbox("Enter the text!")
 
Winsock.SendData("589," & iText)

2 things to notice, the 589 which will be our command for inititaing the function the dilimeter (,) and then our text.

When the client recieves this data it needs to interpret it.....

VB Code:

'Data arrival
 
dim idata as string
dim icommand as string
dim temp() as string
 
Winsock.GetData(iData)
 
temp = split(idata,",")
 
icommand =temp(0)
 
If icommand = "589" then
     call ourFunction(temp(1))
End if
 
'then our function
 
Private sub ourFunction(TheText as string)
     msgbox(thetext)
end sub

Just think of some effective ways of doing it uses small commands as not to waste memory etc :)
