I had knowledge in C# language and web application. I would like to know what is the window command to track the temperature of 4 RX 560 GPU which had installed on my PC.
I had find all of the resources in internet , but couldn't find any relate windows command line to track the temperature. Or if there is any DLL or API to track the temperature?
My purpose is to do a window services which keep track the temperature and push the temperature data to other server over the internet.
Appreciate if anyone can give me guidance.
There is a similar question here on SO (although in that question it is about the CPU temperature): How to get CPU temperature?
The answer of #Jens provides information about Open Hardware Monitor. Although it first seems like an application, there's also an interface available.
More info from the site:

I am making a C# app to capture graphic from an avermedia pcie capture card.
But it seems that there are no out of box tools to do so.
So I made a C++ directshow app to do the capture, which is a console app and opens a capture window when running.
How can I redirect the output to a C# app? for example, to a CaptureElement?
So you want to have XAML CaptureElement connected to AverMedia PCIe capture card. This sounds like a well-understood challenge overall, however every other piece of technology you mentioned is eventually a bad choice: DirectShow, multiple apps with piping, redirection and fitting of cutsom code to XAML CaptureElement control.
Microsoft has intentionally been limited ways you can integrate different APIs and so there are not so many ways to get everything together.
Let us go over the supposed integration path. The capture card is supposed to be shipped with a compatible driver:
Video capture devices are supported through the UVC class driver and must be compatible with UVC 1.1
When this is the case, such devices are visible to Media Foundation API handling video capture among tasks. XAML CaptureElement would be able to see a video capture device through this API and this way everything is supposed to work without need to fit anything from your end.
If this is not happening, it suggests you are dealing with an unsupported device coming without suitable or compatible driver.
Previous media API in Windows was DirectShow but its days are gone. It remains perfectly working as a legacy framework, a lot of applications out there are still relying on it. Specifically it will not integrate with new technology like XAML and UWP. More to that, even Media Foundation itself, the current media API, in its public offering is lagging behind when it comes to fitting with most recent technology. Having said that it is a good idea to stay well clear of DirectShow here if this is at all possible.
I see no need for cross-process design with video travelling between process through piping. There is no good reason for such design and even though this can work efficiently (Windows itself proves it can work great in terms of performance by having so called Frame Server service in it), this is not to be built on piping. In your case it is unlikely to be have to be built on multiple processes either. Instead you can develop a native code DLL project that takes care of video acquisition and connects to managed code via suitable glue layer: C++/CLI, COM, C++/WinRT and such.
Then next thing is fitting to XAML CaptureElement. The control is designed to work with Windows.Media.Capture.MediaCapture class that talks to hardware and you don't have suitable hardware as you plan to implement your own acquisition layer. Long story short you are not supposed to forward external data to CaptureElement and you would have hard time doing this. Your best strategy is to upload externally obtained data to Windows.Graphics.Imaging.SoftwareBitmap or alike and take involved performance impact as acceptable. That is, you will be dealing with video frames as images.
An alternative way is to upload acquired video frames into Direct 3D 11 textures and it would open you a more performant way of integration with video related controls, such as Windows.UI.Xaml.Controls.SwapChainPanel however it would also require that you put much more development effort in there.
I am working on a project which includes a lot of VoIP functions. I don't have access to the source code of the previous system that was being used so I can't dissect it to find out what I need to know. I will describe how the previous system used to work and then ask my question.
First, the old system that we have been using depends on Physical Phones which receive calls over the internet. There is a Desktop App installed on our computer which somehow takes the phone call received by the phone and shows that phone number on the Desktop App. Which uses that number to look up data about the caller. But the problem is that this Desktop App is over a decade old and has not been updated since. So we want to build a new Web Based Application with .NET that will do the same. My question is:
1- How do I fetch the Caller Information From the Physical Phone and use it how I want? The phone being used is SNOM 760 but its possible that other brands or models be used in the future.
2- Let's say that a specific page is always opened on the browser. How do I transfer the caller number to the server and then show a pop up with the information about the caller in that page that's always opened in the browser in a RELIABLE way? What about when that specific page is not opened? Remember that the phone that is receiving this call is not directly in communication with the server. But that is also not a restriction. I read somewhere while researching that I could have my server take the call first and then transfer it to that physical phone. The only restriction is that we use VoIP phones/numbers.
Like I said, I have very vague information on the subject. Any help is appreciated. I've studied that I could use Twillio or other such third party services to achieve this task but I just wanted to know if I can do it myself instead of relying on someone else and hoping they don't shut down their services in the next few years.
Those are a lot of questions jammed into 1 there, I'll try to answer some.
As you already tagged it, TAPI is an option but not very easy to get into. TAPI normally get it's information centrally from the PBX, but in your particular case the SNOM system has the phones themselves connect to a central server to gather the information and distribute it there. You may be able to hook into a proprietary protocol.
Gathering calls on a central server to then distribute them to phones is usually done with an IVR (Interactive voice response). Channeling outside calls through it is easy but the problem with getting your call information from this point is usually you miss the internal calls.
Your website pop-up is not my area of expertise, maybe someone else could comment on the feasibility of that, but personally I would go with a task-tray style app if reliability is your highest priority.
I have a Raspberry Pi 3 running Windows 10 IoT Core. My question is; would it be possible, or is there a way to monitor the CPU temperature of the device either via a remote PowerShell connection, locally on the device in the command line console or if all else fails using a C# deployed app on the device?
I confess to being a C# noob, hence it being my third option.
Why?... I'm planning on building a custom case out of Lego for a stack of several devices and want to assess whether I need to purchase a bunch of heat sinks and cooling fans etc.
Many thanks for your time and assistance.
I hope this can guide you to the right track.
In order to access to low-level BCM2836 peripherals that the IoT SDK or PowerShell client does not provide, you'll need to write your own drivers.
You can follow the code samples from https://github.com/ms-iot/bsp/tree/master/drivers, it's written under WDK framework so you'll need to get yourself familiar with that in order to get started.
I guess eventually you'll end up with something like one of those samples under the drivers sample.
When you're done, deploy your driver follow this tutorial https://developer.microsoft.com/en-us/windows/iot/win10/samples/driverlab3
I'm not 100 percent sure this is the right way to go, but if someone could correct me or point out a better solution, I would be more than happy to learn from it.
i know this is most likely a duplication and i am truly sorry for that but most of the solutions i found was either +7 years outdated, bugged or consume so much memory
all i need is an efficient way to access the webcam to record and display to use it in a computer vision project to detect moving objects and such, with an HD output (using HD camera of course)
also if there is a library that would help with the computer vision that would also be great
any information, tips or experience would be highly appreciated, thanks in advance and have a wonderful day.
You could use AForge.net, it's available as a nuget package and gets the job done.
Here is an example of it. It's a winform application, but I use this library in WPF app as well.
[EDIT] Actually, I think I found what you're looking for, download this. It's a piece of code that has been written for a french azure contest. It's a motion detector written with aforge.net. There is 2 part to it, the first is a wpf client that capture movement. The second is an azure website where the image captured is uploaded automatically.
Having searched high and low for native c# hook to webcam, I found 5 basic ways to interact with the camera.
Video for Windows (VFW)
DirectX
avicap32.dll
WIA

My requirement is to take a photo. The application will be used on some legacy windows XP and Vista machines, but going forward Windows 7 and greater will be required. So what might the best approach be with the broad install base? Just reading WIA looked like the way to go but looks like some changes were made so it works a little different now (I don't know for sure). I understand that some people have done combos.
Might need to crop photo, but that is really about it.
For school visitor monitoring.
I think the best thing is to use the WIA. I know a third party toolkit that could help you doing your requirements which is leadtools. You can check this Tutorial
I would always try to pick up something already on the web and tweak it to my own needs... some open source project or an example where the mainly portion of my app is already made.
on Codeplex you can find a nice library to work with webcams and it's simply called
WebCam Library for WinForm and WPF with C# and VB.NET
Give that a try, maybe you can even help the project, by contributing your own findings, and everyone is a winner... isn't Open Source a great idea?!
