Yes. The description of the GetAsyncKeyState function says:

I usually define a couple of constants so I can call GetAsyncKeyState like this:

Code:

---

Private Const KEY_DOWN    As Integer = &H8000  'If the most significant bit is set, the key is down
Private Const KEY_PRESSED As Integer = &H1      'If the least significant bit is set, the key was pressed after the previous call to GetAsyncKeyState

Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal vKey As KeyCodeConstants) As Integer

Private Sub Timer1_Timer()
    If (GetAsyncKeyState(vbKeyEscape) And KEY_DOWN) = KEY_DOWN Then
        'The Escape key was pressed
    Else
        'The Escape key isn't being pressed
    End If
End Sub
