Applies To: Project Object

The SetMain method returns true (.T.) if the file you specify is set as the main file. False (.F.) is returned if the file you specify is not in the project or the file you specify is not the proper file type.

The main file is a program (.prg file) or form (.scx file) that serves as the execution starting point for a compiled application, and from which other components of your application are called. Typically, the main file sets the application's operational environment, runs menu programs or forms to display the application's interface, and establishes the event loop of the application with the READ EVENTS command. You must designate a main file in the Project Manager before you can create an application (.app) or executable file (.exe) from the project.

Note
Specifying a file as the main file in a project also sets the project's MainFile property.
