{1. PostKeyEx32 function}
procedure PostKeyEx32(key: Word; const shift: TShiftState; specialkey: Boolean);
{************************************************************
* Procedure PostKeyEx32
*
* Parameters:
* key : virtual keycode of the key to send. For printable
* keys this is simply the ANSI code (Ord(character)).
* shift : state of the modifier keys. This is a set, so you
* can set several of these keys (shift, control, alt,
* mouse buttons) in tandem. The TShiftState type is
* declared in the Classes Unit.
* specialkey: normally this should be False. Set it to True to
* specify a key on the numeric keypad, for example.
* Description:
* Uses keybd_event to manufacture a series of key events matching
* the passed parameters. The events go to the control with focus.
* Note that for characters key is always the upper-case version of
* the character. Sending without any modifier keys will result in
* a lower-case character, sending it with [ssShift] will result
* in an upper-case character!

* Procedure PostKeyEx
*
* Parameters:
* hWindow: target window to be send the keystroke
* key : virtual keycode of the key to send. For printable
* keys this is simply the ANSI code (Ord(character)).
* shift : state of the modifier keys. This is a set, so you
* can set several of these keys (shift, control, alt,
* mouse buttons) in tandem. The TShiftState type is
* declared in the Classes Unit.
* specialkey: normally this should be False. Set it to True to
* specify a key on the numeric keypad, for example.
* If this parameter is true, bit 24 of the lparam for
* the posted WM_KEY* messages will be set.
* Description:
* This
procedure sets up Windows key state arrayto correctly
* reflect the requested pattern of modifier keys and then posts
* a WM_KEYDOWN/WM_KEYUP message pair to the target window. Then
* Application.ProcessMessages is called to process the messages
* before the keyboard state is restored.
* Error Conditions:
* May fail due to lack of memory for the two key state buffers.
* Will raise an exception in this case.
* NOTE:
* Setting the keyboard state will not work across applications
* running in different memory spaces on Win32 unless AttachThreadInput
* is used to connect to the target thread first.
