Hi, guys....I am new here and need some help.
I am trying to create a program that will disable the keyboard and mouse and then enable them back.
My program will run under windows 95, so the API BlockInput will not work. And, my program should be able to disable the keyboard and mouse even when my program is not on focus (because my program will call other application and simulate some keystrokes, which will cause other applications to gain focus).
I had tried the following code, but it is not working. Something's wrong...?

Private Sub Form_Load()

g_hMouseHook = SetWindowsHookEx(WH_MOUSE, AddressOf MouseProc, App.hInstance, App.ThreadID)
g_hKeyboardHook = SetWindowsHookEx(WH_KEYBOARD, AddressOf KeyboardProc, App.hInstance, App.ThreadID)

Sleep 5000

If g_hMouseHook Then
Call UnhookWindowsHookEx(g_hMouseHook)
g_hMouseHook = 0
End If
If g_hKeyboardHook Then
Call UnhookWindowsHookEx(g_hKeyboardHook)
g_hKeyboardHook = 0
End If

End Sub

Or is there any better suggestion...?
By the way, I am using VB5

Thank you.
