Hello and Good afternoon! In this post, I will demonstrate on how to install Tailwind CSS 3.0 which is the latest version as of this writing using Tailwind CLI and Visual Studio Code Terminal. The steps presented in this article are derived solely from the documentation which is then applied to an empty web project using Visual Studio Code IDE and it's built-in terminal. This framework was introduced to me by a ex-colleague of mine who's now focused on working with the latest front-end JavaScript and CSS frameworks. According to the documentation, Tailwind CSS is a highly customizable, low-level CSS framework that gives you all of the building blocks you need to build bespoke designs without any annoying opinionated styles you have to fight to override. In a nutshell, it is a utility-first CSS framework for rapidly building custom designs. Ok enough talk and let's get down to business. 1. Create a projects folder called test-project with three subdirectories namely cs...

Good afternoon! In a situtation where you add string values to a StringBuilder object using the AppendLine() method and you want to delete the last character, you might expect that using the Remove() method in the code below will work. But the truth is it does not. private static void RemoveLastCharacter() { StringBuilder sb = new StringBuilder(); sb.AppendLine( "Lorem ipsum dolor sit amet, consectetur adipiscing elit," ); sb.AppendLine( "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua." ); sb = sb.Remove(sb.Length - 1, 1); Console.WriteLine(sb.ToString()); } Using Appendline() method to populate the StringBuilder object according to the documentation will also append the default line terminator after the string value to the end of the StringBuilder instance. Since the default line terminator has two characters specifically "\r\n", we need to include those two characters plus the last character of the string. The revise...

Good evening, This blog post demonstrates on how to upload or send a form with multiple files using HttpPostedFileBase class which is a property of a model class using jQuery and ajax in ASP.NET MVC. Given a sample model, I have declared a HttpPostedFileBase array property which is responsible for handling multiple files. public class clsWeeklyStatusReports { public Guid ID { get ; set ; } public string DomainName { get ; set ; } public string EmployeeName { get ; set ; } public DateTime SubmissionDate { get ; set ; } public string SubmissionDateDisplay { get { return SubmissionDate.ToString( "MM/dd/yyyy" ); } } public string MimeType { get ; set ; } public string FileName { get ; set ; } public HttpPostedFileBase[] Files { get ; set ; } public clsWeeklyStatusReportsGM() { ID = Guid.Empty; DomainName = string .Empty; EmployeeName = string .Empty; MimeType = string .Empty; FileName = string .Empty...

Hello, Given the input element with an autofocus directive that on page load, this control get's focused right away. <input v-autofocus :class= "{ 'error' : empname.length > 22 }" /> The code to automatically focus the control is shown below using the inserted() method. directives:{ autofocus: { inserted(el){ el.focus(); } } } For some reasons the code above does not work in Vue.js 3x. After reading the docs, the solution that work was to use mounted() function instead of inserted() method if you're using Vue.js 3x. directives:{ autofocus: { mounted(el){ el.focus(); } } } Cheers!

Good evening! After adding the node modules using 'npm i' command in a Quasar or Vue.js project, I needed to show that folder in Visual Studio Code project explorer window since it's part of the project. Some of the solutions provided was to add some json configuration in settings.json which did not work. The solution that worked for me was to alter changes in Visual Studio Code Preferences itself. To proceed, go to File -> Preferences -> Text Editor -> Files and scroll down to locate the Exclude pane. Hover to the node_modules value and click the 'Remove Exclude Item' button. After that, the node_modules folder appears in the project explorer window. Cheers!

Good evening, We have this Notepad++ Plugin project that will read and parse an html document converted from a MS Word file and then change the html string into an Adobe In Design format. The issue is that the html document has over 20,000 plus lines even reaching 40,000 lines or more. The code below will get all the text from an active Notepad++ window but fails if the string content is huge. public unsafe string GetText( int length) { byte [] textBuffer = new byte [10000]; fixed ( byte * textPtr = textBuffer) { Win32.SendMessage(scintilla, SciMsg.SCI_GETTEXT, (IntPtr)length, (IntPtr)textPtr); return Encoding.UTF8.GetString(textBuffer).TrimEnd( '\0' ); } } After doing some debugging and troubleshooting, I found a solution that is to replace the size of the textBuffer variable from a static value 10000 to the actual length passed into the function parameter. public unsafe string GetText( int length) { byte [] textBuffer = new byte [length]; fix...

Hello, In this blog post, I'll demonstrate on how to develop a Notepad++ Plugin (64 Bit) using Visual Studio 2019 and C# assuming that you have installed a 64 Bit version of the latest Notepad++ Editor. This tutorial is based from kblisted Notepad++ Plugin Package in GitHub . The plugin's architecture can communicate with the Notepad++ or the underlying Scintilla engine using NotepadPlusPlusGateway and ScintillaGateWay and Win32 API. To start with, download the Notepad++ Plugin Pack from the GitHub page and copy the zip file to the Project Templates folder of your Visual Studio 2019 IDE. In my laptop, the path is "C:\Users\my_username\Documents\Visual Studio 2019\Templates\ProjectTemplates\Visual C#" . Open your Visual Studio 2019 IDE and create a project using the Notepad++ Plugin template. Change the Platform Target to x64. (Our OS is Windows 10 64 bit) Create a function called SetFirstCharAllWordsCap inside Main.cs that get's the entire string content ...

Gents Good Day! There was a question on forums on why the BindingNavigator control was either missing or grayed out in Visual Studio Toolbox of which the project's target framework is .NET 5. I decided to create a C# Windows Forms application using Visual Studio 2019 that targets the .NET 5 framework and infact, the BindingNavigator control is missing. After searching the net, I found an interesting link in StackOverflow Activate missing Winforms controls in .Net Core 3.1 which is applicable to .NET Core 3.1. I applied the steps stated in the post's answer to the Windows Forms project that I created and it works. Below are the steps to do that. 1. Comment Application.SetHighDpiMode(HighDpiMode.SystemAware); code in Program.cs file. static void Main() { //Application.SetHighDpiMode(HighDpiMode.SystemAware); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault( false ); Application.Run( new Form1()); }...

Good day! Normally, in a situation where you want to inject thousands of rows to the database using C# and SQL Server, the optimal solution would be using built-in SQLBulkCopy() function. However, you may encounter the error message "The given value of type String from the data source cannot be converted to type nvarchar of the specified target column. String or binary data would be truncated." The code below works but in some instance may throw that kind of exception. private bool SQLBulkCopy<T>( string SqlConn, List<T> inList, string tableName, ref string errMsg, int optBatchSize = 5000, bool optTableLock = true ) { SqlBulkCopyOptions lockType; SqlTransaction transaction; if (optTableLock) lockType = SqlBulkCopyOptions.TableLock; else lockType = SqlBulkCopyOptions.Default; try { using ( var connection = new SqlConnection(SqlConn)) { connection.Open(); transaction = connection.BeginTransaction(); using ( var bulkCopy ...

Hello, I was trying to retrieve data from a Free Fake API website called JSON Placheholder using the code below which using asynchronous behavior. However, this does'nt return data after all. async getDataAsync(){ try { let response = await fetch( 'http://jsonplaceholder.typicode.com/todos' ); console.log(response.data); this .todos = response.data; } catch (error) { console.log(error); } After doing some research, I came up with a solution and replace the code above using JavaScript Promise as a means to retrieve data from the Fake API website in an asynchronous manner. await fetch( 'http://jsonplaceholder.typicode.com/todos' ) .then(response => response.json() ) .then(data => { this .todos = data; }) . catch (error => { return Promise.reject(error); }); } Cheers!
