MapForums

I'm using MapPoint 2006 in VS2008/C#.
I want to plot many points on the map,
typically many thousands, to get a density
type graph.
I'm using something like this,


for (int loopCounter = 0; loopCounter < 1000; loopCounter++)
{
theLocation = axMappointControl1.ActiveMap.GetLocation(lat, longitude, 0);
axMappointControl1.ActiveMap.AddPushpin(theLocatio n, "");
lat += 0.0005;
longitude += 0.0005;
}


to test the concept. My test code works, but seems very slow,
typically 30-60s to plot 1000 points. I also tried using AddShape, but that seemed even slower. Am I doing something wrong? or is this typical sort of performance we are likley to see?
TIA

If your data is geocoded, i.e. you know lat/long for all points, as you suggest from your code sample, and have them in a database, then plot them by doing a data import/link, the only method I know fast enough for such volumes.
I need less than 10 seconds to plot 1000 pushpins such way.

Thanks Renatoa,
obj.DataImport is much quicker, < 3s to plot 5000 points, from an excel file. When we do this for real datasets will already be in memory, so should be even faster!

Do you know if there are any hard limits on the number of pushpins that can be displayed?

Thanks Again
