Re: New Virtual Earth Article - Clustering with MS AJAX and C#

Hi,

I'm using the Virtual Earth in my application and I saw your Clustering code and it is simply fantastic. I try use your code, but don't works in Virtual Earth 5.0.

I saw that Microsoft published the Virtual Earth 5.0, but I don't know about difference between both versions.

You it could adapt your Clustering code for for Virtual Earth 5.0?
I appreciate.

thanks
PS.: Sorry my English.

Yes there are a few changes, V5 just got released and I'm away in Thailand. I'm back in a few weeks and will update it to reflect the changes - you can subscribe to this site on the contact us page to keep updated.

Re: New Virtual Earth Article - Clustering with MS AJAX and C#

Hi again,

I use the clustering (version C#) and I have a problem. I need to show different images (Authors and Books for example) for cluster points and nocluster points.

I tried to add the image name to the XML this which is ok, but then I get a mess when encoding/decoding. What would be your concept to pass the pushpin type?

thanks a lot

Re: New Virtual Earth Article - Clustering with MS AJAX and C#

I try to keep the cluster example as simple as possible. I use a bitmask to encode the pin types - eg 1 maybe McDonalds, 2 KFC, 4 Pizza hut, 8 Burger King - using a bitmask means you can get something like 7 then means the clust is 1+2+4=7, MD,KFC and PH. I pass these through a bit like the bounds in the csv file, one per clustered pin and store them in the clustered pin js object in the same way as the bounds. When I draw the pin i then select the appropriate icon based on this value.
Hope that helps!

Re: New Virtual Earth Article - Clustering with MS AJAX and C#

I will publish the system after populate the database and post the URL here.

Thanks again, your help was very important.

Re: New Virtual Earth Article - Clustering with MS AJAX and C#

In your "addPinsWithinRange" method you compare the x and y coordinates of points to "clusterwidth" and "clusterheight", but these variables don't depend on the zoom level. I think they should because at low level zoom too many pins are displayed, and at higher level zooms not enough. What do you think?

Re: New Virtual Earth Article - Clustering with MS AJAX and C#

forget my previous message, I had an error in my code (I was always passing 10 for zoomlevel...)
now it works great!
