Cassini Desktop Adapter : Standalone Desktop VWG Applications

Modified By rdhatch on 5/14/2009 4:45:17 PM)

Hi Guys -

I just created a Screencast & Code Snippet for running your VWG Applications standalone on the desktop - without ANY installers.

Double-click & run your VWG Applications in ASP.NET mode.

Please watch Screencast here. Jump to 3:50 to see the end result.

No IIS Installation Required
No Gizmox Installation Required
No Cassini Installation Required

Hope it helps you!

Ryan

PS. You can also download the CodeSnippet.

That's great, it's a nice way to run the app but I am trying to figure how you access your data. Is there a centralized database?

Hi Martin -

You can run it against any database you'd like.

Embedded / File-Based DB (such as: SQLite, MS Access, SQL Server Express)

Central DB (such as: SQL Server, MySQL, etc.)

Just as you would a normal desktop Windows application. So you can develop full-fledged Desktop applications in VWG, instead of WinForms. One of my clients had this requirement - where they needed a multi-user desktop application that could also used as a full web application. Another one of my clients had this same requirement - full web application w/ an offline desktop application counterpart. The software application I'm developing for them is a sales tool - and their sales people can't always obtain internet access at customer sites. If they want, we will be able to synch back & forth between online (web) & offline (desktop) modes using SQL Replication.

You can provide both a desktop & web version of your software - all from the exact same codebase.

Making sense?

Sure it makes sense, and it's very interesting.

I am curious about the data synch back mechanism.

Supose the web app use a cantralized SQL Server database, when the app is used offline (with cassidi), it's the same application, so same code, but the db is not available so look like to me the application will throw an exception.

Does your business layer knows when it's offline and then call portion of code made for this exact purpose? And if so, where is the data is store. When does the app knows when and how to synch back?

Thank you
