Winsock Question

[yocrazymonkey]

Hey,
I need help sending a string with winsock and have winsock recieve the string as a string.
Example:
Public Sub Hello()
dim hello as string
hello = "HI!"
winsock1.senddata (hello)
End Sub

But when winsock1 receives this, it receives "HI!"
How do I make it so it recieves the string hello with the contents still inside the string?
Thanks,

You can't send the actual named variable, if that's what you mean. But all you have to do to send a string is this:
Winsock1.SendData "This is some text haha 1 2 3"

um...
I'll give you an example of what I need.
I'm making a multiplayer game in vb6 and I want it so when a player moves, winsock sends
image3.top as 3top
image3.left as 3left

and when winsock receives it, it makes image3.top = 3top
and image3.left = 3left

Thanks,

OK, you could do something like this:

Winsock1.SendData "3top " & Image3.Top

Then in the receiving side:

Winsock1.GetData mystring
Select Case Split(mystring, " ")(0)
Case "3top"
    Image3.Top = Split(mystring," ")(1)
Case 'other

End Select

Now, this is just a simple way to get started, if you have a large number of things to update, you will want a better way to handle it. You can probably send the actual code such as "Image3.Top = " & Image3.Top then parse it on the other end and run CallByName on it. But this is more involved and you should be fine with the method I gave above for now.

Can you please explain the code that you gave me.
So I understand it.

Of course. What this does is grab the first portion of the string which ends at the first space. That's what Split is doing. So you check that and it finds "3top" so then we know that we'll need to change Image3.Top so we do that using the second portion of the string, which is the Image3.Top value from the sender. Just to illustrate the Split function, if you have the following data:

str = "This is a string."

Then you do this:

Dim s() As String 'this creates a dynamic array, which simply means a group of variables that can change at runtime
s = Split(str, " ") 'now the data is split up into different variables, using the space character as the split point

So now the s() array looks like this:

s(0) = "This"
s(1) = "is"
s(2) = "a"
s(3) = "string."

Hope this helps.

Edit: The way I use Split in my winsock example above is just a shortcut version of it. Instead of putting it in the s() array I am using it directly, so I write Split(somevar, " ") and add the number of which piece I want in parentheses on the end: Split(somevar, " ")(0) or Split(somevar, " ")(1) etc.

Sorry for the double post.
Hey thanks for the help.
Do I have to give credits to you in my game if I use what I learned from you?

[danecook21]

I appreciate you asking but no, not at all. If I had written a large part then I may like credit but just some snippets, feel free to use how you want!
