我看错问题了啊，汗！上面这个是限制一个程序的运行，下面这个应该到达你要求：
Private Type RECT
left As Long
top As Long
right As Long
bottom As Long
End Type
Private Type POINT
x As Long
y As Long
End Type
Private Declare Sub ClipCursor Lib "user32" (lpRect As Any)
Private Declare Sub GetClientRect Lib "user32" (ByVal hWnd As Long, lpRect As RECT)
Private Declare Sub ClientToScreen Lib "user32" (ByVal hWnd As Long, lpPoint As POINT)
Private Declare Sub OffsetRect Lib "user32" (lpRect As RECT, ByVal x As Long, ByVal y As Long)
Private Sub Form_Load()
Command1.Caption = "上锁"
Command2.Caption = "解锁"
Text1.SetFocue
End Sub
Private Sub Command1_Click()
Dim client As RECT
Dim upperleft As POINT
GetClientRect Me.hWnd, client
upperleft.x = client.left
upperleft.y = client.top
ClientToScreen Me.hWnd, upperleft
OffsetRect client, upperleft.x, upperleft.y
ClipCursor client
End Sub
Private Sub Command2_Click()
If text1.text="#密码" then
ClipCursor ByVal 0&
else
msgbxo "密码错误，请重新输入"
text1.SetFocus
endif
End Sub
Private Sub Form_Unload(Cancel As Integer)
cancel = -1
End Sub
这样，只有输入你的密码才会解锁
