ok so Im still a complete noob to vb and trying to build this great aplication any ways heres the problem i have i have put toghter a basic chat aplication using sockets now the problem is when i tell it to send the font to the server and then back to the client it goes to the server in a text format like so ..
[Font: Name=Microsoft Sans Serif, Size=8.25, Units=3, GdiCharSet=0, GdiVerticalFont=False]
Now I am assuming that my problem is that the font and Text are being sent in the same data packet but i dont know how to change this please advise here is my source for server and client...

This is my first time working wit clients so anything will be helpfull but if some one could find it in there heart to explain to me how to change it and why im doing each step that would be great and would help give me a much better understanding of using sockets to transfer data....

[/color][/size]ok so theres the current code with the problem of it printing the font in the text recive box still in there Now if some one could tell me how to make it chang the font in the box txtDisplay bassed on what the client sends to the server i would greatley appreciate it. This is my first time working wit clients so anything will be helpfull but if some one could find it in there heart to explain to me how to change it and why im doing each step that would be great and would help give me a much better understanding of using sockets to transfer data....
