السلام عليكم ورحمة الله تعالى وبركاته عندما نتحدث عن توسيط النماذج والتقارير لابد من الأخذ فى الاعتبار ان خاصية PopUp لها تأثير كبير فإن كانت PopUp = True لها أكواد تقوم بعمل التوسيط للنماذج والتقارير داخل الشاشة خاصة ولا تقوم بعملها ان كانت PopUp = False والعكس كذلك واحيانا ننسى ذكر هذا الأمر عند عرض الاكواد والامثلة ولذلك تعمل عند البعض ولا تعمل عند اخرين بل واحيانا اثناء التصميم ننسى هذا الامر ايضا ومن أجل ذلك بعد البحث المرير وترتيب الأفكار بفضل الله تعالى تم دمج الأكواد حتى تعمل تبعا للخاصية PopUp ايما كان اعدادها حتى وان نسى المستخدم ذلك الامر أوحتى إن كان لا يدرى عنه شئ المرفق الاتى ان شاء الله به حل المشكلة تماما طيب ما الفرق بين عمل الاكواد مع خاصية PopUp ان كانت PopUp = True يتم توسيط داخل الشاشة نفسها تبعا لابعاد شاشة العرض نفسها مهما اختلف مقاس الشاشة اما ان كان PopUp = False يتم التوسيط داخل اطار تطبيق الاكس نفسه الاكواد كالاتى اولا كلاس ولابد ان يكون اسم الكلاس clsAutoCenter وان احببتم تغيير الاسم فيجب تعديله فى الاكواد التى تخص الموديول بنفس الاسم الجديد اولا الكلاس : clsAutoCenter '|---01/11/2021__________________________________________________________________________________________| '|___www.officena.net_______________________|___________________________________________________________| '| | | '| __ _ | _ +-----------officena-----------+ _ | '| \ `/ | | /o) | ||||| | (o\ | '| \__`! | / / | @(~O^O~)@ | \ \ | '| / ,' `-.__________________ | ( (_ | _ ----oOo--Moh--oOo----- _ | _) ) | '| '-'\_____ U `-. | ((\ \) +/o)----------3ssam---------(o\+ (/ /)) | '| \____()-=O=O=O=O=O=[]====--) | (\\\ \_/ / \ \_/ ///) | '| `.___ ,-----,_______...-' | \ / \ / | '| / .' | \____/________Mohammed Essam________\____/ | '| / .' | | '| / .' | 01/11/2021 | '| `-' | | '|_____www.officena.net_____________________|___________________________________________________________| '|_____Thank you for visiting https://www.officena.net__________________________________________________' Option Compare Database Option Explicit Private Type RECT 'RECT structure used for API calls.
