Generates all output files defined in the mapping using a MapForce internal mapping language. The names of the output files are defined as properties of the output items in the mapping. This method is identical to GenerateOutput except for its return value containing the resulting messages, warnings and errors arranged as trees of AppOutputLines.
Note: This method can only be used when the MapForce (running as a COM server) main window is visible, or is embedded with a graphical user interface. If the method is called while MapForce is not visible, then an error will occur.
