Error window

Good day,
Well friends I want to know is, how I can do to make the SAP instead of showing the red at the bottom when it fails, I display it in a window, something like when youconfirmation sample to create a document.

They said that this issue has to do with the SDK, if any of you have a manual inSpanish or Spanish archives would appreciate it.

I hope I can help.
Greetings.
