In the MDI (Delphi) mode program, there will be a main form and a number of sub-forms. Subform and master form are in the same project. And I have an idea now: 即 即 子 f f and the master Form Subform is placed in the DLL, the main form is called the Subform in the DLL. The effect is the same as the MDI mode program (the menu of the subform will be merged into the main form.) Please point out the respective High view.
