Auto Update

[gpearson]

What I do in my application is my "Splash" Screen is the one that gets compiled as a standalone. This stack has code to check for internet connection, create sqlite database, check for an xml file on a website. It checks the difference between a custom property and the xml tag to see if a newer version is online. If it is, it downloads a zip file, extracts the file and runs another stack which is the main application. For my applications I have been naming them the application name.dat

In my zip file is just the updated stack of the main application and any other files that the stack would reference.

Hi
I need advice on creating auto update system for my app.
I have stack "Main" with custom properties and Splash stack that will be compiled to standalone, and will check for if new vers. of app. is available , and download new "Main" . This can I do.
What next ? any tutorial with examples.
Something else that is the problem when I try to download "new Main" stack from my web site is not useful if I use main.livecode , I just can't download it. When I change file to main.rev it is better, I can download but file is corrupted. Do I have to build standalone with new "main" ? then upload it to server ?

How do you guys do it ?
Practical code/ stack example ?
