Hello, After downloading and installing Git and some reason git commands don't work on the command prompt. This could be a case of git not added to the Environment variables path. This assumes that the Git software has been installed properly on your machine. So to fix this error, you need to open System Properties, click Environment Variables. Add the bin and cmd paths of the Git software similar to the picture below. Once they're added to the System variables, git commands will work as expected. Cheers!

Hello, I've noticed in a while that my LG 34" Ultrawide Monitor is hotter when I switched the display modes thru the On-Screen Control software. As I researched thru the internet, I found an article from LG Support on why the LG Monitor screen seems so hot. A useful tip led me to check the brightness of my screen. And behold, it has a value of 100% that causes the temperature to be warmer compared to other monitors. After reducing the brightness and contrast, I felt like the monitor's temperature dropped significantly lower which is acceptable to me. The article can be found here LG Monitor - The Screen Feels Hot Cheers!

Good day gents! As I was about to push my docker image to Docker Hub, I was met with an error "denied: requested access to the resource is denied.". After searching the net, I found the solution that is to login your username using the command " docker login -u your_username " followed by your password using Windows Powershell. Once done logging in, push the image to the repository using docker push command "docker push your_username/dockerdemo". Reference: Docker Denied Requested Access To The Resource Cheers!

Hi all, Another issue that I encountered while learning Docker specifically build a docker image using .NET Core is the "ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref 405e1ab5-1d6a-4b32-b558-cdcae05e5207::q4alx8yd9wbrz32p1zv7s1yg7: "/dockerdemo/dockerdemo.csproj": not found". My project is a simple ASP.NET Core Web API project. After doing some research, the solution that works for me is to cut the docker file "DockerFile" from the folder that contains the .csproj file. Then paste it to the root folder of the project that contains the solution file (.sln). Run again powershell and execute docker build command that points to the root folder of the project where the docker file is cut and pasted. That's it!

Hello Team, I started familiarizing containerization concepts using Docker in .NET Core in the event that our team will embrace the application of containerization to our certain projects in the near future. When I installed the Docker desktop, it prompted an error "Docker Desktop Requires A Newer WSL Kernel Version Issue. Update the WSL kernel by running "wsl --update" or follow instructions at https://docs.microsoft.com/windows/wsl/wsl2-kernel." The fix to this issue is either running the "wsl --update" command similar to the screenshot below. Or download and install "wsl_update_x64" package from here Linux Kernel Update Package Cheers!

Hello, In one of the parser that I made, I need to extract the node name which is in a self closing XML tag as part of the requirement for the output. In order to do that, you need to combine a positive lookbehind for the lesser than symbol (?<=<) and positive lookahead for the forward slash and greater than symbol (?=/>). And then perform a greedy search in between those groups. The complete pattern for that is presented on the code snippet below. var NodeValue = Regex.Match(lstTempNodes[i], @"(?<=<)(.*)(?=/>)" ).Value.Trim(); Here's the pattern matching of several self-closing XML tags.

Hello, Most of us C# developers are working on Dictionaries to store multiple sets of data with unique keys. And in times that we need to modify our logic with the Dictionary object involved, we normally do that using looping construct. Given a simple Dictionary object below with int as key and string as value. Dictionary< int , string > styledLines = new Dictionary< int , string >(); We may thought that looping through this object with the code presented below may work. However, when running your app, this will cause a "Collection was modified; enumeration operation may not execute" issue. It's because we are using the collection's key directly. foreach ( var kvp in styledLines) { styledLines[kvp.key] = $ "Series# {seriesNum} "; } To fix that we have a couple of options. Given that our key is an integer type with values in sequential order such as 0...1000, we could use for loop to change the values such as below. var startI

Hello Everyone! In relation to the previous post on updating the serialization and deserialization using BinaryFormatter class to NewtonSoft's JsonSerializer, we also need to change the Binder functionality using NewtonSoft. The class below inherits the SerializationBinder and overrides the BindToType() function. sealed class HELPERSCustomBinder : SerializationBinder { public override Type BindToType( string assemblyName, string typeName) { if (!typeName.ToUpper().Contains( "SYSTEM.STRING" )) { throw new SerializationException( "Only List<string> is allowed" ); } return Assembly.Load(assemblyName).GetType(typeName); } } The class above will then be assigned to the Binder property of BinaryFormatter as shown from the code snippet below. public static T BuildFromSerializedBuffer<T>( byte [] buffer) where T : new () { MemoryStream MS; BinaryFormatter BF; T rtn; rtn = default (T); try { using (M

Good evening! Part of the migration of our parts cataloging WPF application to .NET 7 was to investigate obsolete code and refactor that to something acceptable and maintainable in the future. One of which that needs to be addressed is the BinaryFormatter class used for serialization and deserialization. Searching thru the internet presents tons of options but since the application has already a Newtonsoft.Json package, we decided to use it's serialization instead. So to proceed with, below are the sample serialization and deserialization functions that incorporates the BinaryFormatter class and converted to NewtonSoft.Json.JsonSerializer. Below is a function using BinaryFormatter serialization. public static byte [] GetSerializedBuffer<T>(T itemToSerialize) { byte [] rtn; MemoryStream MS; BinaryFormatter BF; if (! typeof (T).IsSerializable && !( typeof (ISerializable).IsAssignableFrom( typeof (T)))) throw new InvalidOperationException( "A ser

Good day! Following a tutorial on Xamarin.Forms, I encountered this issue namely " adb is not recognized as an internal or external command " when running adb commands in command prompt. After doing some research for answers to this problem, I came up with the steps to make it work. First is to locate the path of the adb application which can be found in android-sdk->platform-tools folder Next is to go to System Properties and open Environment Variables form. Under System variables, locate the Path entry and click the Edit button. Copy the folder path of the adb.exe application and add it as a new entry to the System variable Path. Click Ok and restart your computer. The adb command should work as expected.
