استخدام علامات الصور أثناء تجميع البيانات في العلامات الذكية
استخدام علامات الصور أثناء تجميع البيانات في العلامات الذكية
ينشأ الكود العيني التالي كتاب عمل ثم يضيف العلامات الذكية التالية في الخلايا D2، E2، و F2 على التوالي.
&=Person.Name(group:normal,skip:1)
&=Person.City
&=Person.Photo(Picture:FitToCell)
ثم يملأ مصدر البيانات بالبيانات ويُعيد استدعاء الأسلوب WorkbookDesigner.Process() لمعالجة العلامات الذكية. يستخدم الكود هذه الصور moon.png و moon2.png ولكن يمكنك استخدام أي صورة. تُظهر اللقطة الشاشة التالية إخراج هذا الكود العيني. كما يمكن رؤية، يتم تجميع البيانات في العمود E و F بالنسبة للبيانات في العمود D.
