Hello,

thank you for your interest in our products. Your post (and screenshot) talk about a "trouble", but you do not describe what the trouble (some exception?) is. The screenshot simply shows a code stopped at a breakpoint.

I can *guess* that there might be a problem with typecasting e.Arguments.State to Label. Because, the state is the last argument that you pass to SubscribeItem. And, in your SubscribeItem call, you pass 0. You probably wanted to pass in the reference to the label object you want to update.

But it can be something different - if so, please first describe the issue better.

Best regards
