Ok, so you're generating a map and saving it as an image somewhere.
When you say that you want to convert lat/long to X,Y coords, are you talking about X,Y coords within the map you generated I assume?
You can get the location object of the lat/long you have with the GetLocation method:
http://msdn.microsoft.com/library/de...etLocation.asp
Then you might look into the LocationToX and LocationToY methods:
http://msdn.microsoft.com/library/de...ocationToX.asp http://msdn.microsoft.com/library/de...ocationToY.asp
This should give you the X,Y coords of the locations you have visible on your map.
Did that helps?
