Dear Friends

In the horizontal Scroll bar control of visual basic, If i cannot isolate the following 2 events

1) i click on the area between the thumb and the left button.
2) i click on the left button of the horizontal scroll bar.

In case i click on the area between the thumb and the left button i want to isolate the event as left area click.
In case i click on the left button i want to isolate the event as left button click.

Same case with the right hand side of the scroll bar.

Can anyone tell me how to isolate the 2 events?

Thanks in advance
Pranav.
