A brief description of the method of setting the focus of the MFC dialog box

This article briefly describes the method of setting the focus of the MFC dialog box, to share with you for your reference. The specific implementation method is as follows:

There are two specific methods:

1. Set the TAB order of the dialog control. Press Ctrl+D to see it. Set the TAB order for the space that needs to be set to focus to 1.

2. The OnInitDialog returns FALSE. The explanation is as follows :(extract to MSDN)
 
If OnInitDialog returns nonzero, Windows sets the input focus to the first control in the dialog box.

The application can return 0 only if it has explicitly set The input focus to one of The controls in The dialog box.

Hope that this article is helpful to everyone's MFC programming.
