Why don't you try telling us what you want it to do?

I'm not sure about the rest of the code, but this block concerns me:

Catch ex As Exception
MsgBox("ACCOUNT CREATED", MsgBoxStyle.Information, "ACCOUNT CREATED")
End Try

If an exception is caugth, that most likely means an error was encountered, which may mean that the account was not created. Catching all exceptions is probably not a great idea either, but that is beyond the scope of this question. I would suggest moving the "Account Created" message to immediately before the catch block and using the cath block to report any errors.
