Is it possible with mappoint drawing a polygon and then search for all user-defined pusphins lying within that polygon?
I want to do this via VB Code. Any ideas?

Thanks a lot

In the help file there is a method "QueryPolygon method" that has an example. I'm not sure if you have seen that and are looking for something else or what?

Yep, it works.

Problem is: Every shape is drawn by a square. I want the user to draw the shap onto the map.
Some codesnipplets / ideas out there?

Thanks a lot

i did the same thing a couple of weeks ago.. you can use all the tools offered by mappoint as long as you use "Close Curve" to create a valid polygone..

only thing you cant use is Highlight ..


i tested with the following . freeform, rectangle, scribble and line.

if you want code i can retreive some..

Code:

      For Each mpShape In mpMap.Shapes
        If mpShape.Type < geoLine Then
          For Each mpData In mpMap.DataSets
            Set mpRec = mpData.QueryShape&#40;mpShape&#41;
            mpRec.MoveFirst
            Do While mpRec.EOF = False
              'Found .?
              If mpRec.Pushpin.Name = "Pin #" & i Then
                frm_main.txt_event = "Found" & i & vbCrLf & frm_main.txt_event
                found = True
                GoTo FOUND_IT 'save some time
              End If
              mpRec.MoveNext
            Loop
          Next mpData
        End If
      Next mpShape
FOUND_IT&#58;

maybe its not the pretiest code.. but it does the job well for me so far

This is what I already have, I need the part of the code for getting the user-defined points for the freeform...
Maybe you have some code-snipplets for that?

Thanks anyway!

What I did now is: I show the user the drawing toolbar so that the user can drw a polygon. But how do I get the polygon programmaticaly so I can execute the queryPolygon method?

Besides: I wanted the user to draw the polygon without the draw-toolbar. Any ideas?

Thanks

Haven't tried it yet but I need to do something similar - what I've thought is to use the MouseDown to log all the points as the user clicks on the map - translate the screen positions to real coordinates using XYToLocation - this provides your location object that can then be added to your own array. Then use the array of location in the AddPolyLine method... well it seems like a good idea :) If I get it working I'll post something.

This is exactly what I need. I do not work on it right now. If you got it first, it would be very nice if you send the code!
