How to add help in vb.net

[san monte]

hi
I am created a help file using HTML Help Workshop. I created help.chm file
I use this file in my project. I connect this file using HelpProvider and set the namespace property to my .chm file.

There are some topics in my help.chm file
like
Account
Adding an account
Income
etc

On every form in my project there is button named help. If i click on this help button the appropriate help related to the form will open. Take a example here

I am on account form
There are three button there
Add
Cancel and
Help

When i click on the help button then i want to open 'Adding an account' topic from the help.chm


I anybody know the solution
Pls. help me

Thanks
