IE Web User Controls deployment in SharePoint 2003 - How to?

Although Microsoft has stopped support for MS IE Web Controls, we would use it when we need some conrols like TreeView in .Net 1.1 - say sharepoint 2003

Steps
1. Add the controls in .ascx (used for web parts)
2. While deploying, copy the Microsoft.Web.UI.WebControls.dll to the bin of WSS root
3. Deploy the above dll in GAC (if required)
4. Run the Build.Bat file from C:\Program Files\IE Web Controls (installation folder). While doing this, care should be taken for CSC.exe location - either run it from VS.Net Command prompt (after switiching to the above location) or include the path of CSC.exe in the "Environment Variables" of system. This will generate a \build\Runtime folder with script file required for the controls
5. Copy the above folder to the root of WSS
6. Exclude the path for the above folder, say webctrl_client (only type the folder name as it is in the root folder) by configuring the virutal server (use SharePoint Central Administration page)

Now it will work!!

How to consume a Share Point web service in ASP.Net web ?

It is always an appreciable effort if we consume an existing system as primary reference instead of storing same data here and there

Follow the steps below:

1. Add web reference in the IDE with URL of SPS site
2. Create a proxy class with WSDL.exe utility (available in the VS.Net Tools menu)
Go to command prompt and type as below
wsdl /out: c:\ProxyClass.cs http://server:90/_vti_bin/lists.asmx
Find more options of wsdl here
3. Consume the webservice via proxy class (shouled be added to the project)
4. Now you should get all the published methods in web service via proxy class
