So my questions are like newbie questions again! I created a couple of test apps, they went fine, but raised some questions 1. In the IW manual (p. 51) it suggests that the server controller contains code like TUserSession = class public end; that you can extend, eg to include user details for the session. The server controller in my test app (using IW 7.something) seems to have a TIWUserSession rather than TUserSession, and this class does not seem to be defined in the server controller. Where should I define what data goes in to my user session? Or is this done differently now - should I create my own class and somehow put it in or associate it with a .data property for the TIWUserSession? I see that in the USerSessionUnit, there is a TIWUSerSession defined - should I simply redfine that one to something like type TIWUserSession = class(TIWUserSessionBase) private { Private declarations } // add username and secuirty level etc fields public { Public declarations } // add getters and setters for username etc end; ? Basically all I want to do is have a text username and security level, and boolean LoggedIn value associated with the user session. It seems the manual is a little out of date (but not as out of date as the Falafel training manual, if that is still at IW 5.1). 2. I decided to hook up a data source to the web app, so I could look up user details. Thinking that the IWUSerSession is a datamodule, I added some database components to it, but it did not seem to like referring to them. So I added a new (standard Delphi) datamodule and put my data components on that. Is this the right thing to do? Or are there problems with threading etc using standard Delphi datamodules? Is the IWUserSession a datamodule or not, and if it is, why can't I just put my data components on that? Thanks in advance!

That seemed to work, anyway. I take it that you always need to use the ServerController unit if you want to refer to/use the UserSession, as that function is defined there?

I have a query in a datamodule, hooked to a datasource. The grid is hooked to that datasource on the datamodule. In the form I have the grid on, I do query.open in the IWForm.create handler. But, I don't see any data in the grid. So obviously I'm doing something wrong (probably something simple!) Any suggestions?

So my questions are like newbie questions again! Best thing to start with are the demos. Check the Features demo, Phonetics Customer Profile , Die Fly! Die, etc to learn how to work wiht hte session object, grids, etc. If you still are unsure how to do it please come back wiht a post.

So obviously I'm doing something wrong (probably something simple!) The problem was the form/datamodule create order. The IWForm was trying to create itself before the datamodule was created (because I started with an IW project with an IWForm and then added a datamodule), so I just needed to swap the order then all was fine.

It is a DM essentially. ok, thx So where is the recommended place to put ones database server connection (if there is a recommended place) - - on the server controller - on the IWUserSession - on a new datamodule created to hold the database server connection I'd lean towards the third, but perhaps it unnecessarily adds a new dm to the project. BTW, when you do your next update, could you modify the IW wizard that comes up from File | New | Other | Intraweb, so that it lets you browse to select the location for the project directory? It's a bit of a hassle to have to remember it or to click back and forth between there and the Windows Explorer to get it.
