I am attempting to create a custom delivery channel for PI System Explorer that will launch a custom splash screen when a notification is triggered. I have attempted this a couple ways:
1. Integrating the windows form code directly into the Visual Studio project.
2. Creating an external "splashscreen.exe" and just launching that from the code.
Neither has been successful. I am able to register the plugin and assign it as a delivery endpoint to our notifications, but upon triggering, I receive the SendError: "Empty Recipient Email". I have perused the sample custom delivery channel plugins (HTML, XML) and am unable to find how to allow this plugin to fully run without a specified contact. Any examples or suggestions would be greatly appreciated!
