Hi, John.

>I have 3 applications. One is desktop VFP application, one is ASP.NET web app and the other is Java web application.
>User requested once they login to either one of the applications above, login should be omitted if they want to access the others.

Is there a specific sequence in whic the user access these apps, or is indistinct.

I ask you that because, for example, if the user always starts from the desktop app, then somehting easy to do is to run the web apps from the desktop, either by launching a browser or by embedding it. In any case, you can always invisibly automate the process of getting into the site, filling in user name and password, and then make the browser vivible to them to go on.

The reverse is not so easy to do, unless you can run the desktop app from the web site also.

Regards,
