Form..::.ShowInTaskbar Property

Gets or sets a value indicating whether the form is displayed in the Windows taskbar.

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

Syntax

Visual Basic

Public Property ShowInTaskbar As Boolean

public bool ShowInTaskbar { get; set; }

Visual C++

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

member ShowInTaskbar : bool with get, set

Property Value

Type: System..::.Boolean
true to display the form in the Windows taskbar at run time; otherwise, false. The default is true.

Remarks

If a form is parented within another form, the parented form is not displayed in the Windows taskbar.

You can use this property to prevent users from selecting your form through the Windows taskbar. For example, if you display a Find and Replace tool window in your application, you might want to prevent that window from being selected through the Windows taskbar because you would need both the application's main window and the Find and Replace tool window displayed in order to process searches appropriately.

You will often wish to use this property when creating a form with the FixedToolWindow style. Setting the FixedToolWindow style does not alone guarantee that a window will not appear in the taskbar.

Examples

The following code example demonstrates how to use the ShowInTaskbar property to make a dialog box that is not displayed in the Windows taskbar.

Visual Basic

Private Sub ShowInTaskBarEx()
    Dim myForm As New Form()
    myForm.Text = "My Form"
    myForm.SetBounds(10, 10, 200, 200)
    myForm.FormBorderStyle = FormBorderStyle.FixedDialog
    myForm.MinimizeBox = False
    myForm.MaximizeBox = False
    ' Do not allow form to be displayed in taskbar.
    myForm.ShowInTaskbar = False
    myForm.ShowDialog()
End Sub

        private void ShowInTaskBarEx()
        {
            Form myForm = new Form();
            myForm.Text = "My Form";
            myForm.SetBounds(10,10,200,200);
            myForm.FormBorderStyle = FormBorderStyle.FixedDialog;
            myForm.MinimizeBox = false;
            myForm.MaximizeBox = false;
            // Do not allow form to be displayed in taskbar.
            myForm.ShowInTaskbar = false;
            myForm.ShowDialog();
        }

Visual C++

private:
   void ShowInTaskBarEx()
   {
      Form^ myForm = gcnew Form;
      myForm->Text = "My Form";
      myForm->SetBounds( 10, 10, 200, 200 );
      myForm->FormBorderStyle = ::FormBorderStyle::FixedDialog;
      myForm->MinimizeBox = false;
      myForm->MaximizeBox = false;

      // Do not allow form to be displayed in taskbar.
      myForm->ShowInTaskbar = false;
      myForm->ShowDialog();
   }
