怎么测试到键盘的多媒体键（如上网键、我的电脑、音量+、音量-，睡眠键、电源键等等
小弟刚刚学习VB,现在公司需要做一款多媒体键盘的测试程序。但是小弟做了一款程序，只能测试107个普通按键啊，其他的多媒体按键测试不了。找到一款前辈写的程序，用的他自己做的 *.dll，但是有很多多媒体按键测试不出来，而且按下WIN键时，还会弹出“开始菜单”，按下“上网键”时也会弹出网页，测试时很不方面。

哪位大哥能帮帮小弟。要能够测试键盘的所有普通按键、WIN键、多媒体键，而不会弹出对话框、网页等选项的。下面是我的VB代码,请各位大哥帮帮改改，谢谢！！

form1里面的代码：

VB code




Option Explicit
Const LEFT_BUTTON = 1
Const RIGHT_BUTTON = 2
Const MIDDLE_BUTTON = 4
Const RED = &HFF
Const NORMAL = &H80000005
Private Sub Form_Load()
    
    On Error Resume Next

    ' 本 KeyboardHook_HookProc ㄧ计
    SetKeyboardHook Me.hwnd, WM_USER

    If Err.Number <> 0 Then
        MsgBox "非 KeybHook.dll 定义之 Windows键", vbCritical
        End
    End If
    On Error GoTo 0
    
    ' 本跌怠祘
    prevWndProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)
    SetWindowLong Me.hwnd, GWL_WNDPROC, AddressOf WndProc
     Dim pOld As Boolean
    
    ' 琵Ctrl+Alt+Del舱龄ア
    SystemParametersInfoByRef SPI_SCREENSAVERRUNNING, True, pOld, 0

End Sub



Private Sub Form_Unload(Cancel As Integer)
 Dim pOld As Boolean
    
    ' 確Ctrl+Alt+Del舱龄
    SystemParametersInfoByRef SPI_SCREENSAVERRUNNING, False, pOld, 0
    '  KeyboardHook_HookProc ㄧ计
    ReleaseKeyboardHook
    
    ' 跌怠祘
    SetWindowLong Me.hwnd, GWL_WNDPROC, prevWndProc
End Sub

Private Sub Label111_Click()
 Dim pOld As Boolean
    
    ' 確Ctrl+Alt+Del舱龄
    SystemParametersInfoByRef SPI_SCREENSAVERRUNNING, False, pOld, 0
Unload Me

End Sub

模块里面的代码：通过 lParam 的值来确定对应哪个按键

VB code

Public Const WM_SYSKEYUP = &H105
Public Const WM_SYSCHAR = &H106

Public Const HTCLIENT = 1
Public Const HTCAPTION = 2

Function WndProc(ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
     If Msg = WM_USER Then
        Form1.List1.AddItem "wParam=" & wParam & ", lParam=" & Hex(lParam)
        Form1.List1.ListIndex = Form1.List1.NewIndex
        Select Case lParam
        Case &H80010201:
            Dim pOld As Boolean
    
            ' 確Ctrl+Alt+Del舱龄
            SystemParametersInfoByRef SPI_SCREENSAVERRUNNING, False, pOld, 0
            Unload Form1
     End Select
    End If
    WndProc = CallWindowProc(prevWndProc, hwnd, Msg, wParam, lParam)
End Function
