Choose MainForm from a list of available forms

Question

Is it possible to choose a form (as a mainform) from a list of \"available\" forms after connecting to the database ? I have a datamodule with 3 \'available\' forms.No mainform

Answer 1

The main form is deemed to be the first form created by a call to Application.CreateForm. So add your selection logic to the .dpr file code, and then call Application.CreateForm to create whichever form the user selects.

// .dpr code
begin
  Application.Initialize;
  CreateMainForm;
  Application.Run;
end.

Here, CreateMainForm is provided by you and implements the user form selection. It might go like this:

procedure CreateMainForm;
var
  Form: TForm;
  FormClass: TFormClass;
begin
  FormClass := ChooseMainFormClass;
  Application.CreateForm(FormClass, Form);
end;

Again, ChooseMainFormClass is provided by you.
