How do I enable my program to read/write another process's memory in C++ without using anything like Windows.h?
I'm running on visual studio in windows 10.
Thanks.
The simple answer is that you can't. Process memory management is inherently OS specific so you need to work with the OS.
I want to write a driver for sensor which can tell me if my yoga 2 pro is in tablet mode or not.
I read some about writting modules but as far as I know, I need to know address in memory which belongs to this device (hope it's correct), and here is my question.
How can I find information about this address?
Or what should I do to find this address?
Both in Windows and in Android you absolutely don't need to write a driver for this purpose. To identify Tablet/Laptop mode, you need just one sensor - accelerometer. In Windows 8.1 + this functionality is built-in, but in case you wish to build your own application you can use an example from here: https://code.msdn.microsoft.com/windowsapps/Accelerometer-Sensor-Sample-22982671
In Android, you have a Java API to all sensors:
https://developer.android.com/guide/topics/sensors/sensors_overview.html
However if you have a custom Linux installed on your Yoga, there indeed may arise a need to add a driver. As of now, the most useful solution are IIO drivers that are part of Kernel:
http://events.linuxfoundation.org/sites/events/files/slides/lceu15_baluta.pdf
If there aren't already there, you'll have to rebuild a Kernel and include those drivers. If you don't know how to find a device address, you have to learn for a while about Linux Kernel in general. Anyway, some tips:
Sensors are normally defined via USB/HID interface
If you still have your Windows along with Linux, you may go to
Devices Manager and there you can easily reach Sensors and see what
address is used by a driver.
Can someone help me understand how display rate is synchronized between platform and kernel. Because I am unable to see the use of vsync, as we used to do in Android ?
So I wanted to know how firefox os do it ?
window.requestAnimationFrame() (or use a JavaScript framework that uses it)
Since I am new to Windows Phone Technology, I want to programatically find in my application that windows device is rooted/jailbrake or not. I found many links but it seems like no way for finding rooted windows device programatically. So is there any way to find rooted/jailbreak windows device programatically any API available for this ? Can anyone help me ?
Thanks
Rooting and/or jailbreaking is not officially supported by Microsoft and therefore there is no official way for you to check if your application is running on such device.
In principle, you could check that, but that check would involve adding stuff to your application that would not pass the certification which means that you can run that application only on jailbroken device.
Which then means that you don't need to check at all since you already know that you are running on such hardware.
Recently I did develop a Symbian application. In Qt simulator it works perfect but in actual device the application terminates unexpectedly. I suspect this is a memory leak issue.
Already i have followed all possible(following) memory cleaning mechanisms:
Creating new objects as pointers.
deleting the objects after use
using 'delete' keyword. using deleteLater() function on ui objects.
But still the application terminates on the device.
please suggest me possible solutions for this.
You can try increasing the Heap and/or Stack sizes using the EPOCHEAPSIZE and EPOCSTACKSIZE statements in your .PRO file
http://qt-project.org/doc/qt-4.8/qmake-platform-notes.html#stack-and-heap-size
Although it may depend on which Qt SDK you are using as the documentation now states that the Qt toolchain already sets these to the maximum possible values.
