وفى نموذج البدء فى حدث تحميل النموذج
 

Private Sub Form_Load()
    HideAppWindow
End Sub

او ان اردت عمل زر أمر لاخفاء اطار الاكسس ضع به فقط الاستدعاء التالى 
 

    HideAppWindow

و ان اردت عمل زر أمر لاستعادة اطار الاكسس مرة أخرى ضع به فقط الاستدعاء التالى 
 

    RestoreAppWindow

ملاحظة هامة
يجب ضبط خاصية النموذج Pop Up =Yes

ملاحظة هامة
يجب ضبط خاصية النموذج Pop Up =Yes

وطبعا لان الخاصية دى لو مش مظبوطة تمام سوف يتم اخفاء اطار اكسس ومع احفاء النموذج تمام وسف تعلق القاعدة فى البرامج المشغلة فى الخلفية ولن تستطيع اعادة فتح القاعدة الا بالاغلاق القسرى من ال/ Task Manager 

ومن اجل ذلك خطر على بالى تعديل كود الاخفاء الى الكود التالى

    End If
