i have a label layer of road name,and a traffic flow layer.

I tried to use double "GMapControl",but it didn't work.

what is 'another tile layer' ?

Jan 7, 2010 at 9:11 AM

i want to add a traffic flow layer.

this 'another tile layer' will get tiles from a tile cached service,and i think it can work as the 'MainMap'.

i tried to add another 'GMapControl' ,but it could not work ...

there is no tiles for traffic ;} all you can add is some objects with coordinates

"there is no tiles for traffic", i have such tile service,it has web mercator projection and the same tile index rule.

and i just want to overlap it on the mainmap, can i use two 'GMapControl'?one loads google map and another loads my traffic tiles.

the traffic flow tiles will be updated regularly. it provides service like google map tiles.

radioman, i want to know, can i use two 'GMapControl' in a Form?

how it will be updated if system puts it first to the local cache?

i set the timer for detecting the traffic tiles server is updated,and then it will get the new tiles replcing the local cache.

now i just want to overlap these traffic tiles on the mainmap,what can i do?

the tiles in cache are not replaced, what will be the point then of the such cache. First basics, then tile stuff...
