How to call InvalidOperationException()

Dears,

Could you help me how to call this box with API?

I'm trying with this code, but didn't get the result.

Throw New InvalidOperationException("")

 Thanks!

try this:

Dim errorManager = ThisApplication.ErrorManager
errorManager.AddMessage("message here", True)
errorManager.Show("Your title here", False, False)
