Describes how to create a dialog.

Types of dialogs

There are two types of dialogs, as follows.

Modal dialog.: While the dialog is displayed, it monopolizes all control of the program, so no other work can be done until the dialog is closed.

Modaless dialog.: Even while the dialog is displayed, it does not monopolize control of the program, so you can push the dialog aside for a moment and do other work.

-	Modal	Modaless
Creation	`CDialog::DoModal()`	`CDialog::Create()`
Destruction	`CDialog::EndDialog()` (available in the dialog implementation class.)	`CWnd::DestroyWindow()`
Instance declaration	Stack (local variable), heap (dynamic allocation)	Heap (dynamic allocation)
Sample	`CModalDlg dlg; dlg.~DoModal();`	`CModalessDlg * dlg = new CModalessDlg; dlg->Create(); dlg->~ShowWindow(~SW_SHOW); dlg->~DestoryWnd(); delete dlg;`

You can check the status of the dialog with the methods below.

Return value	`CWnd::IsWindowEnabled()`	`CWnd::IsWindowVisible()`
TRUE	The dialog is ready to use.	The dialog is actually visible.
FALSE	The dialog is not ready to use.	The dialog is not visible.
