نرم افزار به شکل Active Window یا به شکل Inactive Window

سلام دوستان من باز با یک مشکل دیگه مواجه شدم :oops: من میخوام برنامه ای رو که مینویسم بتون تشخیص بده در پنجره Active (کاربر در حال دیدن و کار کردن هست) یا در پنجره Inactive( کاربر با برنامه کار نمیکنه ) قرار داره .
پیشاپیش ممنون :)

دوست عزیز, با Subclassing میشه اینکارو انجام داد

' in a form

Option Explicit



Public Sub Activate()

    Print "Activated"

End Sub



Public Sub DeActivate()

    Print "Deactivated"

End Sub



Private Sub Form_Load()

    gHW = Me.hWnd

    Hook

End Sub



Private Sub Form_Unload(Cancel As Integer)

    UnHook

End Sub







' in a module
