WNDPROC

متغیرهایی تعریف شده که زمان ارجاع به آن راحت باشید و مقادیری را به آن تخصیص بدهید با Private Type و مشخص کردن نام و دیتا تایپ آن.

Private Type CUSTOM_MSGBOX lTimeout As Long
lExitButton As Long
lInterval As Long
strPrompt As String
End Type

Public cm As CUSTOM_MSGBOX

برای آفیس 32 بیت است نه 64 برای 64 باید Longptr شود .

Private Function WinProc(ByVal lMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long 

Dim hwndCaption As Long 

Dim CurrentStyle As Long 

Dim ClassName As String 

Dim lResult As Long 

Dim Timeout As Long 

اگر پنجره ای فعال شد می بایست ClassName آنرا گرفته و چنانچه 32770 بود یعنی درست است و مطمئن میشوید که خود پنجره مسیج باکس است.

If lMsg = HCBT_ACTIVATE Then

ClassName = Space(256)

lResult = GetClassNameA(wParam, ClassName, 256)

If Left(ClassName, lResult) = "#32770" Then

' Make sure we spotted a messagebox (dialog)

hwndMsgBox = wParam 

Timeout = cm.lInterval 

'IIntrval=10000 Miliseconds

If Timeout = 0 Then

Timeout = cm.lTimeout 

If cm.lTimeout Then 

در اینجا تابع SetTimer عمل میکند و تابع TimeHandler اجرا می شود 

lTimerHandle = SetTimer(0&, 0&, Timeout, AddressOf TimerHandler)

از بین بردن hook که توسط SetWindowsHookEx نصب شده

'Remove Hook Procedure installed By a hook chaib  SetWindowsHookEx 

UnhookWindowsHookEx hHook

End If 

این خط مهم است وگرنه خطا ایجاد میکند.

این یک نمونه کار است هر زمان که توابع API را مطالعه کردید می توانید با چیدمان درست کدها به مقاصد خود دست یابید البته هوک کردن مشکل است اگر خطایی اتفاق بیافتد سیستم هنگ خواهد کرد به WSCRIP.SHELL و POPUT هم می توان مراجعه کرد .
