How to Pull data asynchronously from Database?

[kak.mca]

Hi, Good morning to all,
I am doing VB.NET Windows application.

As per the Client Requirement:

There are nearly about 17 CheckedListBox controls on one single form. I need to populate data from 17 different Queries. They are asking us to do this task using Executing Commands Asynchronously.

I could able to pull data from one table only using Asynchronous method. But, error is hitting when I am trying to pull data from second table.

I am not understanding how to do it. Can anyone please help on this?

Thanks in advance.

Kind regards,
Ashok kumar.

But, error is hitting when I am trying to pull data from second table.

What error is that and what code line is it throwing? What code are you using basically?
