ensure the buffer is properly initialized to all zeros and make sure to tell the sock.receiveFrom to not overwrite what could be the last null terminator
char buffer[256] = { 0 }; <br />
sock.receiveFrom(buffer,sizeof(buffer)-1, addr);<br />
or
char buffer[256]; <br />
ZeroMemory(buffer,sizeof(buffer));<br />
sock.receiveFrom(buffer,sizeof(buffer)-1, addr);<br />

Thanks,
That worked great,

But what happens if you then receive a shorter string of characters from the socket? Parts of "Manchester United" will still be intact. While calling ZeroMemory() may to work, a better solution was suggested by chandu004.

what roger has suggested is good.
but i think, your receive function should return, the number of bytes actually read.
so based on that number, you can cut your string to that many number of bytes.
im not sure but just try it out.

And then NULL terminate...

So can't you just rearrange them via the resource editor?

I'm not entirely sure I see your problem. If it is your program, don't put too many in a row in the first place.
Either by using the resource editor as David suggested, or putting something in the Y parameter of CreateWindow when you call that.
If these windows can move depending on other conditions, and there are a lot of them, then you should look at the DeferWindowPos family of functions.
