• Windows Live Developer Forums Somehow deriving an AddPolygon() from a Live Search Collection

  Dear Group, I've recently begun to experiment with Virtual Earth. I do a fair amount of JavaScript programming in my real job; so I created a rudimentary script to allow me to plot a polygon representing a political district in my city. I'm an alderman running for re-election and I got interested in Virtual Earth as a means to make an on-line map of aldermanic districts. Anyway, here is my rudimentary page: http://www.swerbach.com/Neenah3rd/NeenahAldermanicDistricts1and3.htm Summary of functions: Start: Start recording mouse click positions as LatLong pairs Stop: Stop recording mouse clicks Del Last Line: Remove last polyline drawn on the map Display: Show recorded mouse clicks in new window So click the 'Start' button an ...Show All

• Software Development for Windows Vista Power icon problem

  Hello, I've just installed the Windows Vista Beta 2 (Build 5384) and so far so good, except for one thing: somehow i can't activate the option to show the power icon on the "notification are" of the "taskbar". When i go to the properties of the "taskbar", and then go to the "notification area" options, i'm allowed to select to always show the clock, volume and network icons, but not the power icon. Do you know what can i do to fix this problem Because of this problem, i never know when the battery is low. Thanks for your help!!

• Windows Live Developer Forums Thematic maps?

  Is it possible to build thematic maps using the virtual Earth SDK For example making regions different colours based on their population density. Thanks, Andrew Morten Nielsen wrote: Of course it is possible (well at least with the new API). See http://showcase.sharpgis.net/ve for an example. See that right there is a task that is easy in MapPoint as the boundaries are already defined in the application. However for example if you had point data with the location of every person and you wanted population density for every 100m cell of a grid covering an entire country you would find that this is beyond the functionality of MapPoint. ...Show All
