Hi
I'm porting an app from V2 to V4 and am a bit confused about how drawing and saving shapes now works.
Let's say I have 3 drop down menus. The first one allows me to draw a point, the second a line and the third a polygon.
In V2 I would create 3 shape files and corresponding layers, do a BeginEdit on the correct layer then CommitEdit when finished drawing.
On V4 I have to use TrackInteractiveOverlay. I have it quite happily drawing all 3 shape types on one layer but now want to save.
Do I have to have 3 overlays if I want to save to 3 different shape files? I can't see how this would work as to start drawing I simply say map.TrackOverlay.TrackMode = xx.
Also, how do I then load the shape files in the future and allow them to be edited?
Cheers
Steve
