Do you provide any emulator with dot42 or an actual device is required for testing/debugging?
Is there any way some third party emulator can be attached to debug applications?
You require either an actual device or you can use a VM: http://blog.dot42.com/2013/08/running-android-43-in-hyper-v.html

Currently new to google cloud
and working on vm.
Can anyone help me how can i use android emulator on vm.
it shows me
Emulator: emulator: ERROR: x86 emulation currently requires hardware acceleration!
now how can i enable hardware acceleration on vm??
First of all you can not access BIOS on Google Compute Engine VM. When you restart the instance you will be automatically disconnected from the SSH session. As soon as you open another SSH session again you will be already logged in to the os.
Android Studio Emulator is another Virtual Machine that emulates the operation of an Android device. So what you are looking for is VM nested inside a Google Compute Engine VM, you can refer to the Enabling Nested Virtualization for VM Instances documentation, for further information.
However, you can use arm64-v8a or armeabi-v7a ABI. They are pretty slow but you will be able to test your applications there. You can make them faster, but it will require a powerful VM that will cost a lot of money. To use those images in Android Studio emulator:
Go to Tools > AVD Manager.
On the bottom left corner click on + Create Virtual Device ....
In Choose a device definition, choose any device you want and click Next
In Select a system image go to Other images tab
Choose any arm64-v8a or armeabi-v7a ABI. (Download if you don't have one)
Click on Next, give a name and click Finish
Run the Virtual Device and give it some time, according to how powerful is your VM it will take some time to load. You will see an Android logo loading and after few minutes you will see the Home Screen. If it takes too long, try restarting the AVD and the Android Studio, then leave it some time to load. It is pretty slow, but it is working, I tested it myself.
Try below steps -
Open SDK Manager (In Android Studio, go to Tools > Android > SDK Manager) and Download Intel x86 Emulator Accelerator (HAXM installer) if you haven't.
Now go to your SDK directory C:\users\%USERNAME%\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager\ and run the file named intelhaxm-android.exe.
In case you get an error like "Intel virtualization technology (vt, vt-x) is not enabled". Go to your BIOS settings and enable Hardware Virtualization.
Restart Android Studio and then try to start the AVD again.
I need to Disable/Enable a loaded device driver because the device "at times" when connected fails to load properly.
This device is controlled by the user and is POWERED AND UN-POWERED very frequently.
The program which needs to use the driver DETECTS a failure and needs to Disable/Enable which ALWAYS corrects the issue.
But using the SetupAPI methods causes the executable to require ADMIN rights (Windows 7 and Windows 10).
I'm not sure if I need to use "other" coding methods or if SIGNING the executable will remove the "requirement" to run as administrator?
Any ideas would be greatly appreciated.
The problem is that is any used can unload a driver, they'd be able to interfere with other users. Drivers are a shared resource.
"Signing" the executable makes a few warnings less scary but doesn't affect security.
How can I hibernate a Windows machine that runs Windows 7 or 8 over my LAN from another PC?
Is there a WinAPI function for that? Or do I have to send special magic packets or something like this?
All I know is that PsShutdown.exe is able to do it (allegedly. I haven't tried it).
I don't want to use third party libraries and I also don't want to run a service on the computer that is supposed to get hibernated. I want to use the existing mechanism.
I'd also like to know if I need to change specific settings on the target computer.
I'm not sure if that's important, but shutdown /s /m \\ComputerName did not work on my target PC.
The TechNet document Restart or Shut Down a Remote Computer and Document the Reason describes the requirements to use the shutdown.exe command against a remote computer.
In order to use this feature, the Remote Registry service must be enabled on the remote computer.
Access to the Remote Registry or membership in the Administrators group on the remote computer is the minimum required to complete this procedure
To the best of my knowledge, the only way to remotely hibernate a machine is to use the same method that psshutdown does: copy an executable to the remote machine and install it as a system service.
The OpenSCManager API allows you to specify a target computer, and you can use the handle it returns to call CreateService and then StartService. The service can delete itself once it has done its work.
I code for Windows desktop platform and I need to test my desktop app in a multiple monitor configuration. What is the easiest way to do that? (Well, besides me buying the needed hardware...) I guess I'm asking about a virtual platform to do that. (It seems like VMware workstation does not support such feature.)
VirtualBox can emulate a system with up to eight monitors.
How do you integrate Remote Systems Explorer and CDT plugin inside eclipse ?
What I mean is that you can use Remote Systems Explorer (RSE) plugin to work on C++ code on a remote linux box inside Eclipse but when you try to compile, you basically run a shell command through SSH. The CDT plugin is unable to locate the remote system and off course the remote compiler.
Is there a way to integrate both the plugins so that we can use the parsing / suggestion features of CDT for the remote system as well; and also features like remote compilation, remote debugging using SSH only. If this is not possible, then what is the closest open source alternative to the above problem.
While I don't know how to integrate the plugins you mentioned I do something similar to what you want to achieve on a daily basis with SSH's X forwarding.
If the remote box has X libraries installed and you have a local X server running, you can just ssh -CXY ... into the development box and simply run eclipse (or any other X application) there. The process will live on the remote box and, therefore, have access to all the filesystems and tools, but the GUI elements and those alone will be displayed in your local X session. That, though, may require quite a bit of bandwidth. Please see man ssh and X documentation for security stuff and compression settings.
The PTP project is building a remote build for CDT. Not sure how good that works, but you could always use the Terminal view from RSE to manually call your remote build (make).
I have not used it myself, but maybe you could try NetBeans and see if it works for you.
According to page https://netbeans.org/kb/docs/cnd/remotedev-tutorial.html it has everything you need, even
[...] system includes, macro definitions, platform, etc. All of this information is gathered from the remote server and stored locally on your client system, so that when you edit locally the code assistance will work even when the project is set up to use a remote build host.
