Traditionally, browsers have dealt with this challenge on their own, but more complex applications may require more control over the browser's behavior. For example, an input field the user is about to type into might be obscured by the virtual keyboard, so the browser has to scroll it into view.

This flexibility comes at the price that the browser's layout engine has to be informed of the virtual keyboard's presence and potentially needs to adjust the layout of the document to compensate. Unlike a physical keyboard that is always present and always the same, a virtual keyboard appears and disappears, dependent on the user's actions, to which it can also adapt dynamically, for example, based on the inputmode attribute. Showing and hiding the virtual keyboardĭevices like tablets or cellphones typically have a virtual keyboard for typing text.Opting in to the new virtual keyboard behavior.Overview of using the keyboard (Windows Forms.These protected methods are available to simulate keyboard events.įor more information about these events, see Using keyboard events (Windows Forms. This option is only possible within custom controls or forms, because these methods are protected and can't be accessed from outside the context of the control or form. Most events have a corresponding method that invokes them, named in the pattern of On followed by EventName, such as OnKeyPress. The easiest way to simulate keyboard events is to call a method on the object that raises the event.

Once activated, the keystrokes are sent to calculate 10 plus 10. It first searches for an application window with title of Calculator and then activates it.

The following code example uses Send to simulate pressing keys into the Windows 10 Calculator application.

The following code example uses platform invoke to call the FindWindow and SetForegroundWindow methods to activate the Calculator application window, and then calls Send to issue a series of calculations to the Calculator application. Because there's no managed method to activate another application, you must use native Windows methods to focus the other application. To send keystrokes to another application, you first need to activate it. The SendKeys.Send and SendKeys.SendWait methods send keystrokes to the active application, which is usually the application you're sending keystrokes from.

Private Sub Button1_Click(sender As Object, e As EventArgs) private void button1_Click(object sender, EventArgs e) This example assumes a Form with a Button and ComboBox. These keystrokes cause the ComboBox control to display its dropdown. The following code example uses Send to simulate pressing the ALT and DOWN keys together. The specified keystrokes will be received by the active control of the application. To send a keystroke to the same applicationĬall the SendKeys.Send or SendKeys.SendWait method of the SendKeys class. To force the SendKeys class to only use the previous implementation, use the value "JournalHook" instead. If your application relies on consistent behavior regardless of the operating system, you can force the SendKeys class to use the new implementation by adding the following application setting to your app.config file.
