Event Loop

when I start my WebApplication in which there is a WebCanvas where I use the Paint Event I get an error Event Loop | Stack SessionShutDownThread | The application Has Gone off-line. Please try again later.
May depend on what?

It sounds like you’re getting an exception somewhere in your code. Please post the actual stack.

where is it?

Implement the App.UnhandledException event and use code like this to get it:

dim err as String = join(error.stack,endofline) break

Now run the app in the debugger and cause the error. The debugger will stop at that point and you can inspect the err variable by clicking the ellipsis to the right. Copy & paste the contents.
