Hey all
me again
So I want (in my castom app) to show my curent GPS position and keep updating it as I move along... is there any ready code for it or should i just get LAT LOng and refreshe pin position every half second? seams crapy isea to me ... will use too much resources... there should be some better way

any ideas ?
tnx

Hi,

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

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?

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.

how can I highlight the road where I have drove?

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

Does MP supports vector overlies like google maps?

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.

I didnt try to set 1 sec pdates yet (I just didnt figure out the methods how to deley the data, well more likelly skop some data)

As to pushpin I just changing its location, I have initiated the pin separatly
