What event I should use to read left click mouse location all the time?

[JanetDavidson]

Hello Coders.

I had a post already , and nobody answered it .Maybe was too complicated

Now I guess if I split my questions, somebody could help me.

I want to be able to read the left click mouse button coordination all the times . Is it possible ?

Regards,

Janet.

Hi Janet,

Are you looking to monitor the mouse click or mouse move? You mention click but your description sounds like you want to track mouse movements. If you want mouse movements, the best event handler is "Editor.PointMonitor" event in .NET.

Monitoring a click can be tricker and you might have to hook into Windows message filter if you want that.

Maybe you could use PointMointer class

Maybe Something like

        <CommandMethod("LastPoint")> _
        Public Sub LastPoint()
            AddHandler Application.DocumentManager.MdiActiveDocument.Editor.PointMonitor, New PointMonitorEventHandler(AddressOf Editor_PointMonitor)
        End Sub

        Private previousPoint As Point3d
        Private Sub Editor_PointMonitor(sender As Object, e As PointMonitorEventArgs)
            Dim doc As Document = Application.DocumentManager.MdiActiveDocument
            Dim db As Database = doc.Database
            Dim ed As Editor = doc.Editor

            Dim lastPoint As Point3d = e.Context.LastPoint

            If (Not lastPoint = Nothing) AndAlso (lastPoint <> previousPoint) Then
                ed.WriteMessage(vbLf & "{0} {1}", lastPoint.X.ToString(), lastPoint.Y.ToString())
                previousPoint = lastPoint
            End If

        End Sub

    But Gopinath Taget is much more knowledgeable and probably knows the pitfalls and 'gotchas' of this method.

But and entity has GeometricExtents property, and other properties and other methods to figure out if it falls in the rectangle you mentioned in previous post.

My code also makes me cry when I look at it.
