السلام عليكم ورحمة ..

اساتذتي الكرام لدي استفسار عن كيفية نقل المرفقات من  Attachment  الى  Attachment  آخر في نفس واجهة النموذج علماً ان استخدام swap لم تعطي النتائج المطلوبة .

وعليكم السلام ورحمة الله وبركاته:smile:

 

اختي ، انا لست من مشجعي حفظ المرفق في الجدول ، لذلك لا املك خبرة كافية في هذا الموضوع ،

لذا ، بحثت ووجدت مثال ، وقمت بتعديل المثال ليناسب مع طلبك:smile:

 

الكود التالي به وحدتان نمطيتان:

الاولى: CopyAttachment (الوحدة النمطية الاصلية) ، لعمل نسخة من المرفق الى حقل في سجل جديد آخر ، وهكذا يستعمل:

ومثلا نريد نسخ المرفق في الحقل fld_1 في الجدول tbl_1 ، من السجل الذي Emp=25 (هذا الحقل غير الزامي ، فيمكن تجاهله وتركه فارغا) ،  الى الحقل fld_2 في tbl_2 ،

call CopyAttachment("tbl_1", "fld_1", _
                    "tbl_2", "fld_2", _
                    "Emp=25")

.

الثانية: UpdateAttachment (الوحدة النمطية التي عدلت عليها) ، لتحديث حقل موجود اصلا ، ووهكذا يستعمل:

ومثلا نريد نسخ المرفق في الحقل fld_1 في الجدول tbl_1 ، من السجل الذي Emp=25 ، وتحديث الحقل fld_2 في tbl_2 ، الى السجل الذي Emp=30 "

call UpdateAttachment("tbl_1", "fld_1", _
                      "tbl_2", "fld_2", _
                      "Emp=25", "Emp=30")

.

والوحدتان النمطيتان هما:
