The SendKeys statement is limited only to some keyboard presses...
While this code gives you more...
Such as:
1. You cannot send Space Keystrokes in SendKeys (I tried to do it, or maybe I just don't know how), while you can in HitKey...
HitKey Asc(" ") or
HitKey KeyCodeConstants.vbKeySpace
2. HitKey can also perform CapsLock, ScrollLock, NumLock, or other Lock, and other Keys you can find in your keyboard.. Remember to use VB Constants in "KeyCodeConstants"

'Example for the use of the code:
'In you Timer Event
Private Sub tmrKeyPress_Timer()
'Sends Key Spaces every timer event
HitKey KeyCodeConstants.vbKeySpace
End Sub
'Use the VB Default KeyCodeConstants for easier
'use for this code.
