To customize a data exchange application according to CBMail, you need to do the followings :

• Design an user interface for your application.

• Add a button to send one or several transaction data to OutBox in CBMail.

• Define an application name.

• Define ini text file for your application.

• Append your application name and related ini file name into LTblini.Dat in CBMail.
