SendKeys("{F5}");

[giogio1]

Why the following code line
System.Windows.Forms.SendKeys("{F5}");
produces a compiling error :
"'System.Windows.Forms.SendKeys' is a 'type', which is not valid in the given context"
Thank you.

The message means exactly what it says. You can't call a type like that - you can only call a method. The reason you can't call System.Windows.Forms.SendKeys("TEST") is the same reason you can't call System.Windows.Forms("TEST") - those are the names of namespaces or classes but not names of methods.

What you probably mean to do is SendKeys.SendWait("{F5}") but it would be better if you would follow the approach NinjaTrader_ChelseaB uses in the excellent example app RolloverIndications that handles this type of thing much more thoroughly and with less chance of error:

        private void RolloverBtn_Click(object sender, RoutedEventArgs e)
        {
            // its possible for multiple items to have focus each within their own scope
            // https://stackoverflow.com/questions/2052389/wpf-reset-focus-on-button-click

            // get the scope of the button
            DependencyObject scope = FocusManager.GetFocusScope(rolloverButton);
            // explicitly remove the focus from the button
            FocusManager.SetFocusedElement(scope, null);
            // remove keyboard focus
            Keyboard.ClearFocus();

            // explicity give the chart focus
            ChartControl.OwnerChart.Focus();

            // send a key event to trigger the instrument overlay selector to appear
            Keyboard.FocusedElement.RaiseEvent(new TextCompositionEventArgs(InputManager.Current.PrimaryKeyboardDevice,
                    new TextComposition(InputManager.Current, ChartControl.OwnerChart, "open sesame"))
                        { RoutedEvent = TextCompositionManager.PreviewTextInputEvent });

            // send the actual string you want in the instrument overlay selector
            Keyboard.FocusedElement.RaiseEvent(new TextCompositionEventArgs(InputManager.Current.PrimaryKeyboardDevice,
                    new TextComposition(InputManager.Current, ChartControl.OwnerChart, nextExpiryString))
                        { RoutedEvent = TextCompositionManager.TextInputEvent });

            // optionally send the enter key
            if (!Prompt)
                Keyboard.FocusedElement.RaiseEvent(new KeyEventArgs(Keyboard.PrimaryDevice,
                        PresentationSource.FromVisual(ChartControl.OwnerChart), 0,  Key.Enter) { RoutedEvent = Keyboard.PreviewKeyDownEvent } );
        }​

Hello giogio1,

Thank you for your post.

SendKeys is not officially supported by the NinjaScript support team. That said, this thread will remain open in case any community members, like Bruce, would like to chime in.

You could check out the RolloverIndications indicator - it sends key commands from a button press on the toolbar. This indicator is publicly available on our NinjaTrader Ecosystem website:
