I want to create a map control which will be a server side control.I want to have it as a tool in the toolbox.
The above control will contain providers that will fetch maps from the following sources:
2) Oracle Spatial DB
4) MS Virtual earth.
How to create the providers for the different map sources?
Then I hav to create different screens which will take the parameters and send them to the map preoviders. The map providers will send the generated map to a map control (could be a active X control) or something else.
The map control should also be capable of performing standard functions like pan,zoom etc.
Pls give some idea as well as source code on how to start with it.
Thanks for ur replies.

Just been distracted for ages looking at various new mapping developments but I eventually tracked down the page that I was looking for [:)]
This site has library which abstacts away dependance on a single mapping provider which allows you to use multiple mapping providers using the same api:

Thanks for your reply.
I found the providers for Google,WMS(using Openlayers) and MS but there is no provider for Oracle Spatial DB.
I am not sure whether it can be done using Openlayers, since I have used openlayers for Postgres spatial DB.

I am a bit out of my depth here because I dont really understand it but I think the Oracle Spatial DB is a storage format rather than a mapping technology.
You would take the data from the Oracle Spatial DB and then convert it into a format which can be loaded into google, openlayers, bing etc.
If this is correct then you should be able to use the open source GDAL library which contains OGL.
You should then be able to convert your Oracle Spatial DB data into either KML or GeoRSS which can be loaded directly into Google Maps at least, maybe others.
