How to Get a point outside a VB.form in Button Add-ins?

EnzheLu

Well, I have already find some way to get a point. However, they cannot work appropritately. For example, OnMouseDown event is not exist in Button Add-in classes. Furthermore, OnMouseDown Event in VB Forms can only work in side the form. So I sincerely asking for if there is any other way to obtain a point outside the form within Button Add-ins? If it is appropriate, would you like to show me the sample of codes? I will be really appreciate of it.:cool:

I believe this is what you are trying to do, you will need to reference the appropriate objects in your code as well


        public IPoint getpointclicked(IMxApplication mxapp, ISymbol symbol)
        {
            IAppDisplay appdisplay = mxapp.Display;
            IScreenDisplay screendisplay = appdisplay.FocusScreen as IScreenDisplay;
            IRubberBand rubberband = new RubberPoint();
            IGeometry geo = new Point();
            Boolean result = rubberband.TrackExisting(screendisplay, symbol, geo);
            if (result)
            {
                IPoint point = rubberband.TrackNew(screendisplay, symbol) as IPoint;
                return point;
            }

            return null;
        }
