IMsProblemCalculationCallback.OnWarning

Syntax

OnWarning(Message: String);

Description

The OnWarning method implements the event for displaying a warning on modeling problem calculation.

Comments

For correct use, the method must be redetermined in the user class that is the event handler. Also, this handler must be set in the parameters that are used for modeling problem calculation.

Example

The example displays the description of the user class that is the event handler.
