求解~~~我想监视Esc键
模块：
Public Const WH_KEYBOARD = 2
Public Const VK_SHIFT = &H10
Public Const VK_ESCAPE = &H1B
Declare Function CallNextHookEx Lib "user32" (ByVal hHook As Long, ByVal ncode As Long, ByVal wParam As Long, lParam As Any) As Long
Declare Function GetKeyState Lib "user32" (ByVal nVirtKey As Long) As Integer
Declare Function SetWindowsHookEx Lib "user32" Alias "SetWindowsHookExA" (ByVal idHook As Long, ByVal lpfn As Long, ByVal hmod As Long, ByVal dwThreadId As Long) As Long
Declare Function UnhookWindowsHookEx Lib "user32" (ByVal hHook As Long) As Long
Public hHook As Long
Public Function KeyboardProc(ByVal idHook As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
If idHook < 0 Then
KeyboardProc = CallNextHookEx(hHook, idHook, wParam, ByVal lParam)
Else
If GetKeyState(VK_SHIFT) = 0 Then '换成VK_ESCAPE就什么反应都没有
Form1.Cls
Form1.Print "你按下了Shift键"
End If
KeyboardProc = CallNextHookEx(hHook, idHook, wParam, ByVal lParam)
End If
End Function
=====================
窗体：Private Sub Form_Load()
hHook = SetWindowsHookEx(WH_KEYBOARD, AddressOf KeyboardProc, App.hInstance, App.ThreadID)
End Sub
Private Sub Form_Unload(Cancel As Integer)
UnhookWindowsHookEx hHook
