The typical method for dynamically creating controls in MFC is as follows:

  1. Create() function is used to create a control object, followed by using CreateEx() function to further customize it.
  2. Set control properties such as position, size, style, etc.
  3. Invoke the Create() function to create a control.
  4. Display the control using the ShowWindow() function.

Here is a simple example code:

CButton* pButton = new CButton();
pButton->Create(_T("Click me"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(10, 10, 100, 30), this, 123);
pButton->ShowWindow(SW_SHOW);

In this example, we have created a button control, set the text, style, position, and parent window handle of the button, and finally displayed the button control.

It is important to note that after dynamically creating controls, it is necessary to manually release the control objects at the appropriate time (such as when the window is destroyed) to prevent memory leaks.
