The status of shift keys

The status of shift keys

Visual Basic lets you test the state of the Shift, Alt and Ctrl keys only within the KeyUp, KeyDown and all the mouse-related event procedures. If you want to test the state of these keys from within another routine, you can resort to the following functions:

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As _    Integer' The state of the Ctrl keyFunction CtrlKey() As Boolean    CtrlKey = (GetAsyncKeyState(vbKeyControl) And &H8000)End Function' The state of either Shift keysFunction ShiftKey() As Boolean    ShiftKey = (GetAsyncKeyState(vbKeyShift) And &H8000)End Function' The state of the Alt keyFunction AltKey() As Boolean    AltKey = (GetAsyncKeyState(vbKeyMenu) And &H8000)End Function
