Hey Experts...

Anyone know how to find out the windows handle of an object under the mouse pointer in VB.NET... have found solutions in other languages but no idea how to do this in VB.

I've got a low level hook on the mouse and I'm intercepting the left mouse click... what I need to know is exactly where the mouse was when that click event fired.

Thanks!

Just use the WindowFromPoint() API like this:
Public Class Form1

    Public Structure PointAPI
        Public X As Integer
        Public Y As Integer
        Public Sub New(ByVal pt As Point)
            Me.X = pt.X
            Me.Y = pt.Y
        End Sub
    End Structure

    Public Declare Function WindowFromPoint Lib "user32" (ByVal pt As PointAPI) As IntPtr

    Private Sub Foo()
        ' ... in your callback where you get the left click ...

        Dim curHandle As IntPtr = WindowFromPoint(New PointAPI(Cursor.Position))
        ' ... now use "curHandle" somehow ...
    End Sub

End Class

Open in new window
