I've installed DotNetNuke_Community_06.01.00_Install. The option Host-->Module definition is not displayed

That page is now Host, Extensions.

But i'm not able to create a new module using Host---->Extensions.Can u pls explain how to create a new module and include a new .ascx control.

The "best practice" for creating modules is the approach that Andy is showing in the most recent tutorial series. Basically, you create the module in Visual Studio, turn that into an installable package, and install the module the way you install all DotNetNuke extensions. The first two episodes in this series are available.

There is also an excellent set of tutorials available at DotNetNuke.com. They are done by Chris Hammond. You should start with Chris' blog, specifically this entry: http://www.dotnetnuke.com/Resources...ment.aspx. Be sure to look at the resources mentioned.

Also, Chris has several blog posts related to setting up an appropriate development environment. There are some video tutorials that go with them.

Finally, Chris has created a first class template add-in for visual studio. With it, you can create the stub of a functioning module. It's use is demonstrated in the tutorials that I mention here.

Continuing ...

If you look at our new tutorial series, you'll see that Andy walks you through the steps to create a new module. He does this manually, but his result is pretty much the approach that Chris Hammond's template does for you automatically. From the standpoint of education, following along with Andy will help you understand these steps. If you want to use Chris' approach, you'll want to go through all of the files that are created (and Chris' template creates quite a few more files -- not all are required for all modules.).

If you are interested in module development, you should also pick up a copy of Mitchel Sellers' book on DotNetNuke Module Development. His approach is also slightly different. But, he really explains each piece, so it's a really good compliment to both of these sets of tutorials.

If you take all three together, you'll really get a good introduction to the process and many of the details!

-----
One difference that may be coming up is my understanding that Andy will be using the Linc to SQL approach rather than the full set of abstract and concrete classes. Both are quite valid approaches. If you are interested in more of the Linc to SQL approach, you should also take a look at Michael Washington's adefwebserver.com site and its DotNetNuke help section. There's lots of good stuff there!

All the tutorials u have mentioned again come backs to Host------>Module definition

Great ! Thanks a lot for your reply. It's simply superb
