The Description property setting consists of a short description of the error. Use this property to alert the user to an error that you cannot or do not want to handle. When generating a user-defined error, assign a short description of your error to the Description property. If the Description property is not filled in, and the value of the Number property corresponds to a Visual Basic run-time error, then the string returned by the ErrorToString function is set in the Description property when the error is generated.
