client/server

انا لم اطلع على الكود بعد و لكن هذا ردي السريع اختي....

لماذا لا تسعملي الحزمة ipworks فهي مفيدة جدا و تصلح للعديد من الاستعمالات

وش المشكله بالضبط؟

إذا ممكن أرسلي الكود بشكل كامل إلى المنتدى لأعرف أين الخطأ إن شاء الله

أو أرسليه على عنواني mohannad14@lycos.com

سوري ياجماعه المشكله كانت عندي باللاب توب ... لان البورت كان محجور للكمبيوتر ... والبرنامج الحين شغال ... وهذا هوه للى يريده ..

هذا كود السيرفر ...
