CommonDialog.ShowDialog Method (Window)


Displays a common dialog.

Namespace:   Microsoft.Win32
Assembly:  PresentationFramework (in PresentationFramework.dll)

Public Function ShowDialog (
	owner As Window
) As Nullable(Of Boolean)


Type: System.Windows.Window

Handle to the window that owns the dialog.

Return Value

Type: System.Nullable(Of Boolean)

If the user clicks the OK button of the dialog that is displayed (e.g. OpenFileDialog, SaveFileDialog), true is returned; otherwise, false.

ShowDialog performs initialization tasks for all common dialogs before calling RunDialog. Additionally, the dialog that is eventually shown is assigned an owner window, which is specified by the owner parameter.

In the current implementation, the derived classes (OpenFileDialog and SaveFileDialog) will only return true or false.
