IIMCallback::SendVirtualKey

Windows Mobile 6.5
A version of this page is also available for
4/8/2010

This method is called by the input method (IM) to simulate a keystroke or a virtual key. The key event is sent to the window that currently has the focus; that is, the window that would have received keyboard input if a key had been pressed on an external keyboard.


HRESULT SendVirtualKey( 
  BYTE bVk, 
  DWORD dwFlags
);

bVk

Byte containing the virtual key code of the key to simulate.

dwFlags

Specifies the state of the key. It is any combination of the following values.

Value Description

KEYEVENTF_KEYUP

If this flag is set, a call to SendVirtualKey generates a WM_KEYUP message. If this flag is not set, a call to SendVirtualKey generates a WM_KEYDOWN message.

KEYEVENTF_SILENT

If this flag is set, the key the user pressed to activate SendVirtualKey does not make a keyboard click sound, even if clicks are enabled on the device.

An appropriate HRESULT value is returned.

This function modifies the global key state for the virtual key sent in bVk. For example, an IM can use this method to send SHIFT, CTRL, and ALT key up and down events. These events are retrieved when an application calls the GetKeyState function. This method should send virtual key events that do not have associated characters; that is, it should not send VK_* messages that cause a WM_CHAR message to be sent in the TranslateMessage function. If a character-producing virtual key is sent by this method, the key is modified by the global key state. For example, an application can use this method to send a VK_5 message to the current application. If the SHIFT global key is currently down, the application receives the % character message, depending on the computer's keyboard driver. You can also send character messages and strings using the IIMCallback::SendCharEvents and IIMCallback::SendString methods. Call the SendCharEvents and SendString methods instead of the keybd_event function while programming an IM.
