IGPMessage Interface

Provides access to the properties of a Geoprocessor message.

When To Use

The IGPMessage interface returns a GPMessage object from an IGPMessages array, a collection of GPMessage objects. Messages are returned during the validating and executing of a geoprocessing tool.

Also refer to Building Geoprocessing Function Tools.

Indicates if the message is informative.

Public Function IsInformational ( _
) As Boolean

public bool IsInformational (
);

);

Remarks

The IsWarning method returns true if the message is of type esriGPMessageTypeWarning.

IGPMessage.Type Property
