السلام عليكم

كما تعلمون أثير موضوع جعل الفورم شفافا في المنتدى مؤخرا ... الموضوع على الرابطان:

http://www.officena.net/ib/topic/63786-كود-لجعل-الفورم-شفاف/

http://www.officena.net/ib/topic/63770-transparent-userform-فورم-شفاف/

الكود في الرابط الأول يمكننا من التحكم في درجة شفافية الفورم لكن المشكلة هي أن الشفافية تطال اطار الفورم و ال TitleBar و جميع الكونترولات و كل شيئ داخل الفورم و في النهاية مع زيادة درجات الشفافية كل شيئ يختفي من على الشاشة !

أما الكود في الرابط الثاني فان الشفافية لا تطال الا خلفية الفورم و يبقى اطار الفورم ظاهرا و أيضا كل الكونترولات - ممتاز ... لكن المشكلة هي أنه لا يمكن الزيادة أو النقصان في درجة الشفافية

 

اذن المطلوب هو التمكن من جعل الفورم شفافا مع امكانية الزيادة و النقصان في درجة الشفافية لكن بدون اخفاء اطار الفورم و الكونترولات التي بداخله أي اعمال خاصية الشفافية على خلفية الفورم فقط

هده اشكالية طالما حيرتني كما أنه موضوع مطلوب حله من طرف العديد من مستخدمي و مبرمجي الاكسيل و تطبيقات الأوفيس في منتديات البرمجة لكن لم أجد أي حل حتى الأن

الحمد لله و بعد يومين من التجريب و الاصرار يبدو أنني توصلت الى حل (أو هكدا أتمنى)

طبعا الكود لا يعمل على الأوفيس 64Bit ... لكي يعمل ينبغي تعديل الكود لكن ليس لدي Office 64Bit  لكي أجرب و أقوم بالاختبارات الازمة

الكود يعمل جيدا على ال Modal و ال Modeless  فورم

الكود:

أضف فورم و أضف الى الفورم CommandButton1  و Label1  و ScrollBar1 ثم ضع الكود التالي في اليوزرفورم موديول:

شكرا جزيلا على الردود و التشجيعات

في ما يلي بعض الاضافات و التعديلات على الكود لاستيعاب سيناريو  تحديث خلفية الفورم تلقائيا عند تغيير الصفحات و الملفات في حالة اظهار الفورم Modeless  كما أنني غيرت ال ScrollBar  من اليمين الى اليسار

السلام عليكم ورحمة الله وبركانه

أخي وحبيبي جعفر الطريبق بارك الله فيك وجزاك كل خير على هذا الكود الخيالي والاكثر من رائع

نظراً لاحترافية الاداء وقوة العمل لدي فكرة نرجو منكم عرضها اذا أمكن

هي هل نستطيع ان نقوم بعرض صوة داخل الفورم وفي نفس الوقت تكون شفافة و خلفية الفورم 

بيحث عند ظهور الفورم تظهر الصورة فقط من غير اطار الفورم وتظهر شفافة بشكل بسيط وتوجد فيها الكنترول من تكست بوكس وليبيل 

بحثت صراحة في المواقع الاجنبية ولكن كان الحل ليس في الفورم وانما الحل على ورقة العمل 

أرجو أن تكون الفكرة وصلت لأنها فكرة اذا طبقت توجد لها مكان كبير في مجال البرمجة على أكسل وانشاء البرامج
بارك الله فيك مرة أخرى أستاذنا العظيم على ماتقدمه لنا وأن شاء الله عزوجل يكون في ميزان حسناتك 

تقبل مروري وتحياتي

 هل نستطيع ان نقوم بعرض صوة داخل الفورم وفي نفس الوقت تكون شفافة و خلفية الفورم 

 

أستادي الفاضل أنس

فكرة جميلة لم تخطر ببالي .. لقد تم تعديل الكود لكي يعمل في حالة وجود صورة على خلفية الفورم أو بدون

السلام عليكم

اخي واستاذي جعفر الطربيق قد قدمتي لي وللمنتدئ الكريم فكرة اكثر من رائعة بطريقة الفورم الشفاف وخاصة عندما اضيف صورة في الخلفية 

جاري استثمار هذه الفكرة المبهرة في اكسل لكي يكون قادر التواكب في المستقبل مع البرمجة وخضوعه لاكبر واضخم الاعمال المحاسبية 

اخي جعفر اريد ان الغي شريط التحكم في شفافية الفورم وجعله علئ مستوئ محدد من الشفافية

حاولت التعديل في الكود ولكن لم تنجح الطريقة

مثلا اريد الشفافية مربوطة علئ المستوئ 50% ولكن لانريد وجودالشريط 

بارك الله فيك وجزاك كل خير علئ تطبيق الافكار وتقديمها لنا علئ طبق من الماس 

اخوكم انس دروبي

السلام عليكم ورحمة الله وبركاته

أخي جعفر الطريبق ......!

الملف تمت تجربته على أوفيس 2010/32 بت 

لم يعمل بشكل صحيح كانت النتيجة عند الزيادة والنقصان لم تتغير الشفافية أبداً ظلت على حالها بدون زيادة أونقصان

كما حصل في المشاركة رقم 2 مع أخي وحبيبي عبد العزيز البسكري

فهل هذا الشيئ صحيح أم يوجد خطأ عندنا في نسخة الأوفيس علماً النسخة أصلية مرفقة مع الويندوز

الملف المرفق الذي قدمته في موضوع (كود لجعل الفورم شفاف) يعمل بشكل صحيح على أوفيس 2010 ولكن تنقصه ميزة الصورة داخل الفورم والتحكم في مستوى الشفافية

لو سمحت وتكرمت علي نريد التعديل على هذا الملف المرفق

بارك الله فيك نريد عرض الأراء والفكرة من قبلكم 

تقبل تحياتي ومروري

أستادي الفاضل أنس

جربت على عجالة الملف على أوفيس 32/2010 ويندوز 64 بت في احدى السيبيرات و بالفعل الملف لم يعمل كما تفضلت ولم تتغير الشفافية

للأسف بدون توفري على جهاز فيه الويندوز 64 لن أتمكن بسهولة من معرفة سبب المشكلة ..

احدى مشاكل برمجة ال API هي تعدد اصدارات الاوفيس و الويندوز .. ان شاء الله قريبا سأتوفر على جهاز جديد يعمل على الويندوز 64 و سأقوم بتعديل كل الكودات

أخي جعفر أعتذر عن التأخر في الرد ولكن لظروف الانترنت.....

أخي جعفر كان قصدي أنا في المشاركة السابقة

الملف المرفق الذي أرفقته أنا يعمل بشكل صحيح على أوفيس 2010 32 بت ويعطي النتيجة المطلوبة 

فهل نستطيع أن نعدله بحيث تكون بداخله الصورة شفافة ويبقى الكنترولات موجودة

نرجو التوضيح حول هذا الأمر لوسمحت وتكرمت عليي

جزاكم الله كل خير

تقبل مروري وتحياتي

كما سبق لي و ان قلت انه يصعب علي كتابة الكود المناسب على أنظمة الويندوز 64 بت لأنني أشتغل على الويندوز 32 أوفيس 2007

برمجة ال API تحديدا تتطلب التجريب و اعادة التجريب  .. لقد أنشأت العديد من الأكواد في مجالات مختلفة و التي تحتاج الى تعديل لكي تشتغل على الويندوز 32 و 64 بت في نفس الوقت ... ان شاء الله خير عنما أقتني جهازا جديدا
