السلام عليكم أخواني في هذا المنتدى المبدع .
اواجه مشكلة في كتابة كود لإجبار المستخدم على كتابة تنسيق الوقت مثلاً الوقت 00:00:00 am
فعلى المستخدم أن يعدل فقط ما بين النقط : دون تحريرها أي عند كتابة الساعة يقفز عن العلامة : وينتقل الى الدقائق وهكذا
مع أن يكون العدد الخاص بالساعة 0< و >24 والثواني والدقائق نفس الشيء
و am و pm حصرا حتى لا يتم كتابة ارقام أو احرف أخرى

بدل ما تستخدم مربع نص TextBox واحد ، استخدم أربعة
