كنت قد سألت عن طريقة لعمل Download من احد المساحات على النت بإستخدام الفيجوال بيسك ، وبفضل الله قد وجدت الحل ، فأحببت ان تشاركوني العمل :اولا يتم فتح مشروع جديد ، ومن ثم في قائمة التعريفات يتم وضع هذا الكود

وهو عبارة عن تعريفات ومتغيرات في API ... قبل وضع شفرة التحميل يجب ان يكون لدينا مساحة على الانترنت ولنفترض ان لدينا المساحة التالية
اسم المساحة : www.abc.com
اسم المستخدم : abc
كلمة المرور : 123123

الان يتم وضع الشفرة على حدث الضغط على الزر:

hOpen = InternetOpen("API-Guide sample program", INTERNET_OPEN_TYPE_PRECONFIG, vbNullString, vbNullString, 0)
'هنا يتم الاتصال بالـ FTP
Refresh
hConnection = InternetConnect(hOpen, "www.abc.com", INTERNET_DEFAULT_FTP_PORT, "abc", "123123", INTERNET_SERVICE_FTP, IIf(PassiveConnection, INTERNET_FLAG_PASSIVE, 0), 0)
' انشاء مخزن مؤقت في المجلد
sOrgPath = String(MAX_PATH, 0)
الشفرة السابقة تقوم فقط بفتح الاتصال بالموقع عن طريق FTP وتعطينا رقم هذا الاتصال الى المتغير hConnection
حتى يتم الاستفاده منه في رفع الملفات .

الان يتم وضع الكود التالي والذي يقوم بإنزال ملف بإسم Temp.txt ووضعة في القرص C:\ من الموقع المذكور سابقا :

FtpGetFile hConnection, "Temp.txt ", "c:\Temp.txt ", False, 0, FTP_TRANSFER_TYPE_UNKNOWN, 0


يتم الان اغلاق الاتصال

'اغلاق ال FTP
InternetCloseHandle hConnection
اغلاق الاتصال بالانترنت
InternetCloseHandle hOpen
