السلام عليكم ورحمة الله وبركاته

بدل ما تستخدم مربع نص TextBox واحد ، استخدم أربعة

[ATTACH=CONFIG]1590[/ATTACH]

المستطيلات باللون الأحمر مربعات نصوص Textbox بخلفية بيضاء وبدون BorderStyle
المستطيل الأزرق بانل Panel بخلفية بيضاء وبدون BorderStyle
النقطتين فوق بعض أداتي Label

حدث الـ KeyDown لاستخدام السهم العلوي والسفلي من الكيبورد لزيادة ونقصان القيم
حدث الـ KeyPress لمنع كتابة أي قيم نصية فقط الرقمية
حدث الـ LostFocus إذا كانت المربعات فارغة عند الخروج من الأداة يتم إضافة صفرين 00
