hi ssystems,

here is the code..I am setting tooltip in mouseMove event of listview.It is working fine in vs2003 but after converting it in to vs2008, The tooltip starts blinking.

Private Sub lvActivities_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lvActivities.MouseMove
.
.
.
.
tiptext = "Member Name : " & MemberName & vbCrLf & "Access Number : " & AccessNumber & vbCrLf & "Phone Number : " & telephoneNo

Application.DoEvents()

tipAll.SetToolTip(lvActivities, tiptext)
.
.
.
end sub

Looks like VB WinForms (again I'm guessing here...could be WPF). What framework are we using here? In any case avoid doing doevents. Application DoEvents. You can use DispatcherFrame or event delegation. MultiThread as well.

Hi Santos,

Thanks for ur reply.

Since its converted to vs2008 the framework is 3.5, and its a vb.net windows application.

I tried removing Application.Doevents. but,still blinks.

Hi..
Instead of updating the tooltip on all
events, you only update it if the mouse has moved X pixels away from
where you popped up the tooltip.
