Detect when a user clicks on a listview scrollbar code problem?

[em07189]

HI everyone again.

I have made some changes to the project posted in http://vbnet.mvps.org/index.html?cod...api/index.html.

For my attached project i just want to display a message when the user move down the list or drag the thumb control (I think
thats the name for the little list position indicator?) down/up to scroll at a
faster rate.

The problem here is when the user drags the Thumb control of the listview scrollbar,
what is happening is that the message box is posted several times and i dont know how to make it appear only one time.(i'm a novice in the API).

Thanks for your help.
