Opening a Stack from the Server
This lesson shows you how to open a stack from a server using a desktop based standalone. This technique means you can download data to your application temporarily, administer updates to all your users via the server stack, or connect to other users by using a common stack from the server. It can also be used to reduce the standalone size and for a variety of other purposes.
Step 1: Create the Standalone Launch Stack
From this launch stack, we call the Main Application from the server using this code
on mouseUp
go stack url "http://path/to/your/server/MainApplication.livecode"
end mouseUpStep 2: Creating the main stack which will be opened from server
This is the Main stack which is uploaded to the server. Here we can also get the image from the server using on openCard:
on openCard
set the filename of image "city" to "http://path/to/your/server/edinburgh_004p.jpeg"
end openCardPlease Note: This should be uploaded as a normal LiveCode stack and not as a standalone.
Step 3: Save the Launch stack as Standalone
Step 4: Upload the Main stack and Image to the server
As you can see we have uploaded the raw LiveCode file.
Step 5: Running the Standalone to get the stack from the server
Once we click the button "Get data from Web" the Main stack is opened.
That's it! Pretty simple, but a very useful technique to know.
This functionality is great!!!
Unfortunatly it has problems if the server stack contains the browser widget. This widget is not visible if you load the stack from a server.
Is this a bug or a technical feature?
