I have two items in a form.
First is a textbox and second is combo box.

I have single value in textbox but there is a multiple values for the combobox which depend on the value of the textbox.

When I write in textbox I require an 'ALL' value is available in the combo box.

Can any one solve my problem?

I used MS Access for my backend.
How can I create a table that can be used for a my problem?

Give me any reference or codes.

While returning values from the database, you can actually union an all to your source.

For e.g.

select 'All', null <br />
UNION<br />
<br />
select emp_name,emp_age from emp_table

Something along the lines of...

VB

if textbox1.value<>"" then combobox1.add("ALL")
