}

}

بس تظهر رسالة تفيد

want to receive automatic updating from the

network . receiving updates may result in charges.

is it OK to receive automatic updates

NO Yes

بالنسبه لاخفاء التطبيق يمكن ذلك عن طريق:

getDisplay().setCurrent(null);

مشكور على الرد الجميل والمختصر والرائع

طيب يأ أخي

بعد ذلك كيف يشتغل عند وقت معين

مشكوريت شباب

جرّبت الإخفاء

وجربت البش رجستري كله شغـّال ما قصرتوا شباب ربي يجعل الجنة مثواكم

بس فيه ملاحضة عندما يعمل البرنامج بالبش رجستري بعد وقت معين تظهر رسالة تأكيدية

===================================

| السماح لتطبيق ....كذا.... بالبدء آلياً عند الحاجة |

| |

| لا نعم |

===================================

ممكن عملية عدم السؤال وتجاوز هذه النافذة

بليييز

عفوا أخي نور البدر

بالنسبه للرساله التي ذكرتها فهي رساله security من الجافا ولا يمكن حذفها الا عن طريق تسجيل تطبيقك والحصول على شهاده لبرنامجك من احدى الشركات التي تقدم مثل هذه الشهادات.

مشكور على الرد

طيب ممكن اعمل أكثر من بش رجستري في برنامج واحد

لأن المفكرة تكن فيها أكثر من بش رجستري

جربتها فلم تنفع

private void scheduleMIDlet1(long deltatime)

throws ClassNotFoundException,ConnectionNotFoundException,SecurityException {

//String cn="hello.VisualMidlet";

String cn = this.getClass().getName();

// Get the current time by calling Date.getTime()

Date alarm = new Date();

long t1 = PushRegistry.registerAlarm(cn,alarm.getTime()+deltatime);

}

private void scheduleMIDlet2(long deltatime)

throws ClassNotFoundException,ConnectionNotFoundException,SecurityException {

//String cn="hello.VisualMidlet";

String cn = this.getClass().getName();

// Get the current time by calling Date.getTime()

Date alarm = new Date();

long t2 = PushRegistry.registerAlarm(cn,alarm.getTime()+deltatime);

}

private void scheduleMIDlet3(long deltatime)

throws ClassNotFoundException,ConnectionNotFoundException,SecurityException {

//String cn="hello.VisualMidlet";

String cn = this.getClass().getName();

// Get the current time by calling Date.getTime()

Date alarm = new Date();

long t3 = PushRegistry.registerAlarm(cn,alarm.getTime()+deltatime);

}

private void scheduleMIDlet4(long deltatime)

throws ClassNotFoundException,ConnectionNotFoundException,SecurityException {

//String cn="hello.VisualMidlet";

String cn = this.getClass().getName();

// Get the current time by calling Date.getTime()

Date alarm = new Date();

long t4 = PushRegistry.registerAlarm(cn,alarm.getTime()+deltatime);

}

private void scheduleMIDlet5(long deltatime)

throws ClassNotFoundException,ConnectionNotFoundException,SecurityException {

//String cn="hello.VisualMidlet";

String cn = this.getClass().getName();

// Get the current time by calling Date.getTime()

Date alarm = new Date();

long t5 = PushRegistry.registerAlarm(cn,alarm.getTime()+deltatime);

}

واستخدمتها بالشكل التالي

scheduleMIDlet1(1000*60);

scheduleMIDlet2(1000*60*2);

scheduleMIDlet3(1000*60*3);

scheduleMIDlet4(1000*60*4);

scheduleMIDlet5(1000*60*5);

لم يشتغل أي شي

ممكن من الأخوان التوضيح لماذا

وكيف أعملها كالمفكرة
