re[mapguide-users] fresh map/layer

[Kenneth, GEOGRAF A/S]

I don't think that you can achieve that.
The closest thing you can do is to issue code on the client that 
refreshes the map,
after calling the index increment.

However, the Refresh() method is invoked in an asyncron manner.
This means that your code will continue to execute before the map is 
actually loaded:

mapFrame.Refresh();
i++; //This line will be executed before the actual map is updated.
server.Increment(); //So will this
mapFrame.Refresh(); //This will most likely abort the loading of the 
previous map, and execute before the index has incremented

This means that you will have to hook up to the MapLoaded event.

Secondly, I'm guessing that the speed will be horrible if you want to 
animate using the server rendering.
Instead, you should pre-create overlay images for the map.
Then load each image in an invisible part of the screen.
Once all images are loaded, you can safely animate the map overlays.
