var can be used in reg expr ?

[zhangjiaqiang]

Hello all,

I use different users in a DataTable to login my app each time.

for example, user1 login, then I will get a windows whose title is "user1@IP".

Code:

login_name = DataTable("login_name")

I want to check the title with using varname "login_name" in a reg expr to check this is correct ?

How should I do ?
