Windows Phone Login Username and Password (PHP & MySQL Web Server)

Windows Phone Login Username and Password (PHP & MySQL Web Server) ตัวอย่างบทความการเขียน App บน Windows Phone และการทำระบบสมาชิก Login ข้อมูล Username และ Password โดยข้อมูลของสมาชิกจะถูกจัดเก็บไว้ที่ Web Server ผ่าน PHP กับ MySQL ที่จะทำหน้าที่แลกเปลี่ยนข้อมูลระหว่าง Windows Phone กับ Web Server ขั้นตอนการทำงานง่าย ๆ ก็คือ Windows Phone จะส่ง Username และ Password ไปตรวจสอบที่ฝั่งของ Web Server ซึ่งจะมี php ทำหน้าที่ตรวจสอบและส่งค่ากลับมายัง Windows Phone และหลังจากที่ Login ผ่านแล้ว จะมีหน้าจอ Page สำหรับให้สมาชิสามารถทำการแก้ไขอัพเดดข้อมูลของตัวเอง
