ОШИБКА: если вы используете элементы управления MFC в диалоговом окне, вы не можете #define _AFX_NO_MFC_CONTROLS_IN_DIALOGS

У меня есть пользовательский элемент управления, в котором я пытаюсь реализовать элемент управления сетки https://www.codeproject.com/Articles/8/MFC-Grid-control как показано на этом сайте. https://social.msdn.microsoft.com/Forums/vstudio/en-US/035a3e74-596d-4534-8543-2e6ee545d582/how-to-use-grid-control-in-mfc

Я реализовал код следующим образом

Когда я запускаю это, я получаю следующую ошибку

  atlTraceUtil - Warning: dialog creation failed, so application is terminating unexpectedly.
atlTraceUtil - Warning: if you are using MFC controls on the dialog, you cannot #define _AFX_NO_MFC_CONTROLS_IN_DIALOGS.
The thread 0x3a58 has exited with code 0 (0x0).

Любая помощь будет оценена.

Решение

Я не добавил класс для пользовательского элемента управления, как MFCGridCtrl , Как только я это сделал, все работает отлично.
