Question

让键盘没有反应（就是锁定键盘）的VB代码怎么写？

我不是用来做坏事的，只是想做一个软件，里面含有这个功能，又不知代码怎么写。
我要锁定和解锁的代码，最好实例和源代码一起回答，或者发到我的邮箱：hanzhu9@126.com
我现在刚刚申请百度知道，还没有什么分，大家就帮帮忙吧。

刚申请也有分啊!!!记得给我加分！！！

Declare Sub Sleep Lib "KERNEL32" (ByVal dwMilliseconds As Long)
Const WM_MOUSELAST = &H209
Const WM_MOUSEFIRST = &H200
Public Const WM_KEYLAST = &H108
Public Const WM_KEYFIRST = &H100
Public Const WH_JOURNALRECORD = 0
Public Const WH_JOURNALPLAYBACK = 1

Type EVENTMSG
message As Long
paramL As Long
paramH As Long
time As Long
hwnd As Long
End Type
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
Declare Function CallNextHookEx Lib "user32" (ByVal hHook As Long, _
ByVal nCode As Long, ByVal wParam As Long, lParam As Any) As Long
Public hNxtHook As Long 注释： handle of Hook Procedure
Public msg As EVENTMSG

Sub EnableHook()
hNxtHook = SetWindowsHookEx(WH_JOURNALPLAYBACK, AddressOf HookProc, App.hInstance, 0)
End Sub
Sub FreeHook()
Dim ret As Long
ret = UnhookWindowsHookEx(hNxtHook)
End Sub
Function HookProc(ByVal code As Long, ByVal wParam As Long, _
ByVal lParam As Long) As Long
HookProc = CallNextHookEx(hNxtHook, code, wParam, lParam)
End Function

注释：以下在Form中，需求:一个Command1, 一个text1
Private Sub Command1_Click()
Dim str5 As String, len5 As Long, i As Long

Call EnableHook
str5 = "这是一个测试JournalPlayBackHook的程式"
len5 = Len(str5)
For i = 1 To len5
Text1.Text = Mid(str5, 1, i)
Text1.Refresh
Sleep (200)
Next
Call FreeHook
End Sub
