CSimpleDialog::DoModal | Creates a modal dialog box. |
Remarks
Implements a modal dialog box with basic functionality. CSimpleDialog
provides support for Windows common controls only. To create and display a modal dialog box, create an instance of this class, providing the name of an existing resource template for the dialog box. The dialog box object closes when the user clicks any control with a pre-defined value (such as IDOK or IDCANCEL).
CSimpleDialog
allows you to create only modal dialog boxes. CSimpleDialog
provides the dialog box procedure, which uses the default message map to direct messages to the appropriate handlers.

CSimpleDialog::DoModal
Invokes a modal dialog box and returns the dialog-box result when done.
INT_PTR DoModal(HWND hWndParent = ::GetActiveWindow());
Parameters
hWndParent
A handle to the parent of the dialog box. If no value is provided, the parent is set to the current active window.
Return Value
If successful, the return value is the resource ID of the control that dismissed the dialog box.
If the function fails, the return value is –1. To get extended error information, call GetLastError
.
Remarks
This method handles all interaction with the user while the dialog box is active. This is what makes the dialog box modal; that is, the user cannot interact with other windows until the dialog box is closed.
