all..there is a Replace function for VB.. but I can't seem to get it to work..can it be used for strings?

suppose I have a string :

01 02 03 04

and then I wanna replace 02 with 00,

so, I use Instr function to first locate this 02, and then I wanna replace it..

I tried using Replace function but, it can't seem to work...
