CommonDialog.ShowDialog Method

  • Reference

Definition

Namespace:
Microsoft.Win32
Assembly:
PresentationFramework.dll

Displays a common dialog.

Overloads

ShowDialog()

Displays a common dialog.
ShowDialog(Window)

Displays a common dialog.

Remarks

ShowDialog performs initialization tasks for all common dialogs before calling RunDialog. Since RunDialog requires an owner window, ShowDialog attempts to assign one in the following order of precedence:

  • The current application's active window.

  • The current application's parking window.

  • An internally generated hidden window.
