User Defined Outputs: Messaging Methods

Messaging methods are provided to convey additional information to the user from any of the UDOs methods. The Compute function is the one typically location where such use is anticipated. Any message sent via these functions are displayed in the application’s message window using the appropriate icon.

These functions can also be used for debugging purposes.

• AddErrorMessage(string): Call this method to convey an error condition to the user.

• AddWarningMessage(string): Call this method to convey a warning message: typically used for conditions that are not ideal but can be tolerated by the script.

• AddInfoMessage(string): Call this method to convey an informational message to the user. This is the call to use when outputting messages for debugging purposes.
