OpenFileDialog::ShowReadOnly Property

Gets or sets a value indicating whether the dialog box contains a read-only check box.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
property bool ShowReadOnly {
	bool get ();
	void set (bool value);
}

Property Value

Type: System::Boolean
true if the dialog box contains a read-only check box; otherwise, false. The default value is false.

The following code example demonstrates the use of the ShowReadOnly property. This example displays the OpenFileDialog box with the ShowReadOnly property set to true. If the user clicks the option to open the file in read-only mode, the OpenFile method is used to open the file. Otherwise, the FileStream class is used to open the file in read/write mode.


private:
   FileStream^ OpenFile()
   {
      // Displays an OpenFileDialog and shows the read/only files.
      OpenFileDialog^ dlgOpenFile = gcnew OpenFileDialog;
      dlgOpenFile->ShowReadOnly = true;
      if ( dlgOpenFile->ShowDialog() == ::DialogResult::OK )
      {
         // If ReadOnlyChecked is true, uses the OpenFile method to
         // open the file with read/only access.
         if ( dlgOpenFile->ReadOnlyChecked == true )
         {
            return dynamic_cast<FileStream^>(dlgOpenFile->OpenFile());
         }
         // Otherwise, opens the file with read/write access.
         else
         {
            String^ path = dlgOpenFile->FileName;
            return gcnew FileStream( path,System::IO::FileMode::Open,System::IO::FileAccess::ReadWrite );
         }
      }

      return nullptr;
   }
