Hi,
Microhelp as a freeware file which has the peek&poke commands for VB.
You can call them; or, it's somewhere in the MSBASIC forum of Compuserve.
(I can't remember the file name, though...)

Always be careful when using peek & poke;  when running under protected
mode, very,very,very,very bad things can happen, since essentially
in a nutshell the addresses can change...
