Reg keys in Visual basic 6

Hey, i was talking to a friend of mine who knows about VB.
My question were : "Is there any way i could send my friend a vb.exe file that will create a msgbox on his startup which gives him a message like :Hello Eric.
And possible to change that message from my computer.
He told me "Yeah that's a regkey".
Is there anyway you could possible send me a tutorial on regkeys, i wan't to learn all about it.

Your friend will need to have the vb 6 runtime dependancy files installed on his system too if he already doesnt have them.

Search the Forums for registry keys as there is alot of code already posted on it. ;)

Thank you, I'll try! ;)
