            Serial port blocked by none process
            Asked 2022-Feb-03 at 23:04

            Have an issue managing a SerialPort on Windows 10.

            I need to plug in a serial device to the computer, it works properly most of the times, but in certains situations the port stops working, just refuses any new connection even when any process is using it, the device manager shows the port is available (the driver is loaded).

            Sometimes the SerialPort is available until I disable the port in the device in Windows DeviceManager, restart the computer and enabling it again. Knowing that I've tried using some Microsoft tools:

            • PnPUtil, creating a double click PowerShell script to disable and enable the device. It didn't worked, I had to unplug and plug in physically the serial device. By definition it works with PlugAndPlay devices.
            • DevCon, It makes a similiar thing as PnPUtil, but it specifies that works with any devices pluged to the computer. I made a similar script but got the same result.
            • Handle, I found out the existence of handles, they're like dependencies linked to a process including a device instance (using driver file). When I get the port unused, I tried searching the handle of the SerialPort ("Device/Serial0"), and none process was using it. it's been detected but blocked in someway.
            • ProcessExplorer, this tool is like TaskManager but gives you a detailed view of each processes, including the handles. I confirmed again, the ports is not being used.

            Now I'm thinking about some hardware related problem, the serial port is wired as NullModém, which means that only GND, Tx and Rx are connected. so that way of wiring, can't there be any bussines logic problem under RS232, right?

            An option could be a driver incompatibility with the motherboard serial port?

            Has someone any other ideas that I could try?

            Edit: An under/overvoltage could possibly blocked a serial port?



            Answered 2022-Feb-03 at 23:04

            I kind of solved the problem.

            It turns out that if Windows detects constant data flow when the serial port enumarion starts (system boot or when you enable/load a new devices), Windows identifies the serial port COM as a serial mouse, creating a new devices linked to that serial port. So the port won't be available for any other process.

            I found out the problem reading this refs (including a similar question):

            I'd like to give more details about what I did.

            I made a C# ConsoleApp which constanly sends data to the port by using a USB-RS232 adapter connected to another PC which has a legacy serial port. This is the app's code:



            IMFTransform::SetInputType() 'MF_E_TRANSFORM_TYPE_NOT_SET '
            Asked 2022-Jan-03 at 17:33

            I am trying to set up an encoder IMFTransform. In this case, it happens to be NVENC H264 Encoder. However, IMFTransform::SetInputType() is not working for ConfigureEncoder(), and is returning MF_E_TRANSFORM_TYPE_NOT_SET. This behavior does not occur in the ConfigureColorConversion() function, despite the code being nearly identical. I have tried just about everything and it has not helped at all.

            Answered 2022-Jan-03 at 16:16

            MF_E_TRANSFORM_TYPE_NOT_SET You must set the output types before setting the input types.

            This is behavior by design. You would normally buuild the pipeline along the data flow, but in the case of encoder it's typically reverse for reasons I am omitting here. The error code, as documented, gives you a hint that you need to SetOutputType first and then you would be able to do SetInputType.

            Even though Video Processor MFT is also an MFT, it's type setting is more relaxed.



            Can't install vsix to Visual Studio 2019 - Android Device Manager has a lower version than required by Visual Studio
            Asked 2021-Dec-14 at 21:34

            I have Visual Studio 2019 installed with Xamarin. I'm trying to get Shell to show up in the project templates. I'm following this post as a guide. But when I install the vsix file, it fails with the error message: Installation of Microsoft.VisualStudio.Android.DeviceManager failed. The extension has a lower version than required by Visual Studio. Please install the extension from Visual Studio Installer instead.

            Where in the Visual Studio Installer is the Android Device Manager? I've installed all the Mobile Development tools and all updates....



            Answered 2021-Dec-14 at 21:34

            That post is obsolete - it describes something you needed to do in a Preview version of VS 2019.

            In VS Installer, select Workload "Mobile development with .NET".

            I was unable to find any Microsoft doc that tells you to simply do that!

            I don't recall whether you still need to also do this step:

            Setting up the Android SDK for Xamarin.Android.

            After installing the Workload mentioned above, restart VS. See if the menu item mentioned below is there. If so, try to make a sample app - maybe this "Android SDK" step is no longer needed - the Workload might set everything up.

            Then Android Device Manager will be at menu Tools / Android / Android Device Manager.

            Menu location documented here.



            Unable to run "adb", check your Android SDK installation and ANDROID_SDK_ROOT environment variable: ...\Android\Sdk\platform-tools\adb.exe

            When I start the project popup shows "Flutter daemon terminate" and when starting the flutter application it shows the "No Connected Devices Found" dialog box. Then I run flutter doctor -v doctor found issues in:



            Answered 2021-Dec-04 at 15:36

            Try this step after not working on any of the steps I mentioned in the question.

            The problem was in the antivirus program. It denied access to starting the flutter daemon on port 5037. I simply uninstalled the antivirus program from my device. Then it works like a charm.



            Cannot connect emulator in Android Studio on MacOS
            Asked 2021-Nov-21 at 04:49

            I have a problem with the emulator that I cannot run my app on it. A few months ago, I still can open my old projects and run them on an emulator. After a few months, I come back with a new project and now I can open the emulator but it is not connected with my project (with my old projects too).

            I see there are errors saying faild to start adb when I open my emulator and another notification says daemon is terminated. I google those to find solutions but nothing helps.

            Here is my flutter doctor -v



            Answered 2021-Nov-21 at 04:47

            I solved the problem of

            1. Cannot start emulator (emulator process is terminated)
            2. adb didn't ACK
            3. Flutter daemon is terminated

            Using these steps (Thanks to this post):

            1. Reinstall all Android Studio (After this, I still get the adb + daemon errors)
            2. Restart my Macbook to make sure no adb instance is running (After this I open Android Studio and see no daemon + adb errors but i get the new error when starting emulator called "Dyld Error Message")
            3. Close Android Studio
            4. Download and Unzip this older version emulator
            5. Open terminal and run open ~/Library/Android/sdk, this should open a folder, then replace the emulator folder with the one I just unzipped
            6. Run android studio normally

            OS: MacOS Mojave, IMO this error happens because newer emulator is not supporting old MacOS version. You can either UPGRADE your MacOS or DOWNGRADE emulator version



            Ruby: parsing over a csv file and expecting some text
            Asked 2021-Nov-01 at 12:35

            I have some logs that need analyzing to check if the logs do not have abnormalities and are incorrect form so to speak.

            I have generated a CSV file for it:



            Answered 2021-Nov-01 at 12:35

            i want to parse/iterate through the whole csv file and should as well show me for each line a result.

            That's not possible, see Add a configuration option to continue on failure.

            That said, by modifying a little the code, you can make Rspec check the whole file and display all the rows that fail your expect:



            How to refactor two classes doing the same thing except one method to make them more OOP-friendly?
            Asked 2021-Jun-11 at 15:38

            i have problem about design a module of my project.

            Lets say, you have two classes which both of them almost doing the same thing. You can think like DeviceManager.

            Both of them connect/disconnect/parse exactly the same way. After parse the message from device they need to do different things like one of them print a message, the other one pass it to somewhere else.

            I need to design this structure best as oop allows maybe with inheritance,interface,abstract etc. but i am not sure what is the best way to approach this problem.

            Note: I dont want to violate any SOLID principle.

            From Olivier's answer i drafted this one, i am not sure this is the best approach.

            Do you have bad quality on seeing the local video being rendered? Or bad video quality from the remote participants in the call?




            Error LNK2038 : mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in XX.obj
            Asked 2021-Jan-26 at 16:48

            I'm very new to c++ and was getting this error while trying to build Release versions of my c++ OpenGL project. After some googling I went ahead and changed the Runtime Library in the C/C++ > Code Generation menu to Multi-Threaded Debug GLL (/MDd), which then fixed the issue. I'm wondering if that's the right thing to do though.

            I created a new empty project as a test, and the default Runtime Library setting in Release mode is Multi-Threaded (/MD). The default Runtime Library for Debug mode is Multi-Threaded Debug (/MDd). Despite having different Runtime Libraries, both configs build successfully, which makes me wonder if there's been a mess up in my project setup at some point.

            Another detail that made me curious was the output log while trying to build in Release x64:



            Answered 2021-Jan-26 at 16:48

            Though not a perfect solution, I ended up creating a new project and reimporting all dependencies one after another, compiling in between to try and find the issue. After importing all libraries, the new project just worked. I then copied all of my code and compiled it in the new solution, which worked, so the issue has been resolved.

            I saved a diff between the two project files, but couldn't find the issue (they are too different for me to make sense out of). Maybe someone with more experience can figure it out.
