Standard object orientated multitier design patterns help here. Been around for years.
You need to abstract all your dataAccess code (creating the connection, calling SQL etc.) into a separate DataAccess class. Then from any form in the application just call your dataaccess class.
MSDN tutorial 1: Creating a Data Access Layer[^] should give you a good start point.
If you have knowledge, let others light their candles at it.

I should add that althought the MSDN articl I posted about is for ASP.Net Web Applications the DataAccess logic and code is identical for Windows Forms applications.

In your code, it's no different than if the database server was sitting right next to you.
You have to know how to configure your network and the network the server is sitting in in order to do this. Since there are sooooo many options, services and devices that can be between your client machine and the server, it's pretty much impossible to tell you what you have to do to set this up.

I haven't had the need to do it for a while, but I need to generate help docs from the XML comments in the source code. I've used NDoc in the past but I see that it hasn't been updated since 2005. Anyone have recommendations for alternatives?

I would like to find a starting point to write a .NET application that looks like Develeoper Studio itself. Dockable Windows for stdout,stderr, tree views, ribbon bars etc.
Is there such? Preferably something in WPF, describable in XAML.

To create an app with dockable windows and ribbons you will need a good controls suite with those tools, available from companies such as divelements[^], Infragistics[^], dotnetmagic[^]. And no doubt many more can be found via google[^].

I have already devloped a MLM website in asp 3.0.Its Become slow gradually with increasing records in database.
>After 7000 records in database,when we generate account report.its is not generating.
>for that reason i planning to redesign in asp.net.
>But i am confused what database technic i have to use so that it become faster

Use SQL Server 2008 or Oracle 11g.
There are other factors that determine speed, like the structure of the database, indexes on your tables, the code you write to retrieve data, etc.
