VS 2012 Fake error message

hey guys, sorry that i'm not online all the time cause of some problems!

i'm making a project that need a stub (crypter)

i want to add like a fake error message

so i'm using this
const fmeaz = "TEST"
dim MessageFake as string
If checkbox1.checked = true then
MessageFake = "True" else = "False"

in the stub
Const fmeaz = "TEST"
Dim MessagFake as string
if MessageFake = "True" then
Msgbox("Hello", msgboxsytle.critical,"Testestest")

When I check the check box 1 in the crypter It Does not show the message ? :[
