i've just a little problem...

i'm testing some VB code i need for my application.
i would like to test just a 'part' of the code excluding 'working
lines'
how can i "comment" working' lines in a time ???

actually i put " ' " one by one before the lines i want to exclude
buti took me much time than the testing itself.....

there's a quick way to "comment/uncomment" many lines in a time??
