i have a CEdit control, i need  to add properties to this control to make it able to connect a database and bound it to specific table field ( just like bounding a text field to table filed from a Data control in Visual basic)

Well derive a class from CEdit, give it a member variable which is a CRecordset (or similar), and a few member functions - one which accepts a connection string in SQL for instance.  Catch OnLoseFocus event and update the database/recordset with the altered text.  to It really depends on your needs.

Is there only going to be one edit control in your application that connects?  Give it a CDatabase.

Are there going to be lots of edits connecting to a database?  Give them each a recordset and connect them to a common CDatabase.

Are you only going to be viewing text, or will you need to handle booleans and integers and dates etc? You'll need some validation, or else you'll get lots of "update failed" notifications from the database, which wouldn't be best practice.

This is only the beginning.  You're asking a lot - perhaps you'd like to narrow it down a bit?

If your application connects to a database through a recordset you go to class wizzard , member variables tab and and map the recordset field to the edit box.

try to go to the ClassWizard, go to the Text property, click Data Binding button, and make the property bindable. try the control after this modification, you will see that the needed properties added as needed.
