كيف يتم إيقاف زر Printscreen طوال فترة عمل البرنامج

up

I tried so much but i cann't find the solution

the form discovered all keys except the PrintScreen key

تستطيع باستخدام هذا الكود

 My.Computer.Clipboard.Clear()

وممكن تعمل له تايمر

لكن عيوب هذه الطريقة انها تلغي اي شي في الحافضة حتى اذا كان نص

جرب وشوف

ممكن باستخدام دوال معينة (مش عارفها) تختار الزر الذي تم ضغطه فإذا كان Print Screen يتم تنفيذ الكود

انظر الملف المرفق

مع جزيل الشكر

PS.zip

sorry, i tried that method before and doesn't work

and you should assigne it with the press of PrintScreen key not any thing

Also , where you should put it ?? if you put it in Load event of the form it will clear just when the form load only and

if you put it at Activated event of the form it 'll slow the program because it'll functioning all time as long as the program work

what we need is the enum or code of the PrintScreen key

and then you can deal with it as you like by tracing the key events of the form or any control on the form

you mentioned that this method will clear all thcontents of the clipboard , but you can check about the image by the method " clipboard.ContainImage()" and that method returns true if the clipboard contains image and then you can clear it

طيب ياجماعة ... وبعدين !!!

ملهاش حل يعني ولا ايه ؟؟؟؟
