I have a user control.I want to show a form on mouse enter of that user control.The location of the form is set to the location of the user control i.e the form will be seen in the position of the user control on mouse enter.But the form flickers continuously when the form appears on mouse enter of the user control.How to resolve it?

Private Sub user_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs)
        
        infoForm.Hide()
           
    End Sub
    Private Sub user_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs)
      
        Dim cntrl As UserControl = CType(sender, UserControl)

        Dim p As Point = cntrl.PointToScreen(New Point(0, 0))
     
        infoForm.Location = p
        infoForm.Show()
      

    End Sub

infoForm is the form that I want to display and above code contains the mouse leave and mouse enter events.

It happens. I bet you are doing something wrong on mouse events. What?

Solution 1

try setting the double buffered to tru in your control e.g.

VB

Public Sub New()
  Me.DoubleBuffered = True
End Sub
