Exe How to Load Forms in DLL?

HI

Exe How to Load Forms in DLL?

Code execution does not report exceptions, but the main interface does not display DLL forms。

 

Main Form Calls DLL Code

procedure TfrmMain.UniButton3Click(Sender: TObject);
var
  f: TCreateDLLFormAsChild;
  c: TControl;
begin
  f := GetProcAddress(DLLHandle, 'CreateDLLFormAsChild');
  if Assigned(f) then begin
    c := f(UniTabSheet1);
  end;
end;

 

DLL Form Creation Method

function CreateDLLFormAsChild(parent: TWinControl): TControl; stdcall;
var
 frmResQuery: TfrmResQuery;
begin
  if not Assigned(frmResQuery) then
  begin
    frmResQuery := TfrmResQuery.Create(UniApplication);
    frmResQuery.ParentFont := False;
    frmResQuery.ParentWindow := parent.Handle;
    frmResQuery.Visible := true;

    frmResQuery.Left := 100;
    frmResQuery.Top := 100;
    Result := frmResQuery;
  end;
end;

exports
  CreateDLLFormAsChild;
