Re: Showing GPS position?
Hi,

This is the way to go. Not much recourses, you can move the pushpin every time.

Re: Showing GPS position?
damn, MS could of do the better job....
Do you know if there are any potrntial memory leaks if I will apdate location of the pushpin with the rate that GPS sends its data? its like 10 times a sec...

Also kind of similar question if I have pushpin with the sahpe of the triangle how can I rotate it to show the direction of the movement and how can I highlight the road where I have drove? Does MP supports vector overlies like google maps?

Re: Showing GPS position?
well there is definetly some memory leaks in the code that i made, but its only creationg and focusing on the pin

When i start my gps app my app takes 0-1% of cpu and about 8mb of ram, while mappoint object takes 35% CPU and 35mb of ram, but over 5 hours of ime that changed too 100% of cpu and 400mb of ram while my app (the core) doesnt take anything

I think it is better to update once a second.

You can add some bitmaps that indicates the direction and use them depending on current direction.

You cannot, but you can connect each position with a line, highlight line or an arrow line in color of your choice.

no.

Do you see the same behavour if you update once a second? Do you use 1 pushpin or do you use a pushpin per position? The latter will eat more memory of course. For the former you can move pushpin, not create a new one each time.
