You are programming in pascal and need to find the mainform
Pascal (Delphi) has a predefined structure which can be used to find the mainform quickly
You open the dpr file from the project and look at the end. You will find things like:
Application.Title := 'Appname';
The first form that has been created, is the form that will start the application after the "Application.Run" command in the delphi source code
Hope this makes your life easier.
