Get mouse position

Anonymous — Mon, 09 Dec 2013 18:26:22 GMT

Hi,

How can I do to get the cursor position in AutoCAD. I want to get those coordinates that are in the lower left corner in AutoCAD. I saw a solution in C + + but I could not do the same with VB, I need to do this with VB if possible i even use the Point API but can't link with AutoCAD, how i can handle the cursor in .NET?

Thanks, sorry my bad english.

Hi Josuesasilva,

There is a discussion forum dedicated to AutoCAD .Net API related queries. Posting your query there will help get you answers quickly.

About your query :

The blog post that you mentioned does not use events and relies on the Windows API.

The easier and more reliable way would be to use the events.

To use the PointMonitor event, please refer to this blog post. This lesson also has a sample code in VB.Net.

http://adndevblog.typepad.com/autocad/2012/10/autocadnet-lesson-6-input-point-monitor.html

After you have the PointMonitor event subscribed, you can use the "PointMonitorEventArgs.InputPointContext.RawPoint" or the "ComputedPoint" to get the coordinates.

Regards,

Balaji

2 ways to get cursor position

1, mfc api,

BOOL getCursorPos( MSG *msg)
{
if( msg->message == WM_MOUSEMOVE )//here you can add the message you want to watch
{
CPoint pt1;
pt1 = msg->pt;
acedGetAcadDwgView()->ScreenToClient( &pt1 );
acedDwgPoint pt2;
acedCoordFromPixelToWorld( 0, pt1, pt2 );
}

}

the pt2, is the format of ads_point

2, objectarx api

the objectarx class, AcEdInputPointMonitor, shall do the thing you need, which can be find in the referece guide.

hope these can solve the problems

[CommandMethod("DT")]

public void mousepoint()
{
Editor acDocEd = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
acDocEd.PointMonitor += new PointMonitorEventHandler(ed_PointMonitor);
}

private static void ed_PointMonitor(object sender, PointMonitorEventArgs e)
{
Editor ed = sender as Editor;
ed.WriteMessage("\n" + e.Context.ComputedPoint.X + "|" + e.Context.ComputedPoint.Y);
}

[CommandMethod("DT1")]

public void removeregistry()
{
Editor acDocEd = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
acDocEd.PointMonitor -= new PointMonitorEventHandler(ed_PointMonitor);
}

Sorry but it is ObjectARX forum and not AutoCAD .NET API forum. AutoCAD .NET API forum here: https://forums.autodesk.com/t5/net/bd-p/152
