.NET GENES

Hello, I was converting a .NET core 2.2 console application into a .NET 7 project that will reverse engineer a sample database from Microsoft called ContosoRetailDW as the data source for my Entity Framework Core project. Upon running the Scaffold-DbContext command in Nuget Package Manager Console, an error occured was shown on the window with the specific message "A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)" Scaffold-DbContext "Server=Your_Server;Database=ContosoRetailDW;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models After reading through the forums, the solution that worked form me was to add a TrustServerCertifcate setting with a value to true or Encrypt setting set to false. The latter is the recommended one based from the forum answers. Option...

Good day! I was about to publish one of my .NET 7 console application to GitHub using Visual Studio 2022. And when adding my account, an error occured which states that "There was a problem adding your GitHub account. Your default web browser might be using HSTS for localhost.". After doing some research, I found this post Disabling HSTS for localhost on Chromium-based browsers which fixed the problem for MS Edge or Google Chrome Browsers. First you need to type in the browser url " about://net-internals/#hsts " command to open the Domain Security Page of your browser where you can clear the HSTS. Under " Delete domain security policies " domain textbox, type in localhost and click the delete button. After that, I have successfully added my GitHub account in Visual Studio 2022 and was able to publish my project. Cheers!

Team, In a situation wherein you need to access a WebView2 control properties in a class library and that the WebView2 control is added in a WPF project, all you need to do is to reference the Microsoft.Web.WebView2.Wpf.dll and Microsoft.Web.WebView2.Core.dll from the WPF project into the class library. The sample code below is a utility class located in a class library project which has a WebView2 control object that performs navigation to a url that is set from the WPF project. public static class WebBrowserUtility { public static readonly DependencyProperty BindableSourceProperty = DependencyProperty.RegisterAttached( "BindableSource" , typeof ( string ), typeof (WebBrowserUtility), new UIPropertyMetadata( null , BindableSourcePropertyChanged)); public static string GetBindableSource(DependencyObject obj) { return ( string )obj.GetValue(BindableSourcePr...

Good day! A common scenario to our projects is to use the Overlay concept that is, show a nearly transparent modal on top of our form. I have been using the code below to create an Overlay using just a Border and a TextBlock but to no avail, it just won't sit right on top of the WebBrowser control. In the picture right next to the Border control snippet, only the input controls are covered by the overlay and ignoring the WebBrowser control. <Border BorderBrush= "Black" BorderThickness= "1" Background= "#80000000" Visibility= "{Binding Path=IsBusy, Converter={StaticResource BoolToVisibilityConverter}}" Grid.RowSpan= "4" Grid.ColumnSpan= "3" > <Grid> <TextBlock TextAlignment= "Center" Margin= "0" TextWrapping= "Wrap" Width= "500" Text= "{Binding Path=OverlayMessage}" HorizontalAlignment= "Center" VerticalAlignment= "...

Good day Team, I'm currently working on a project to show some information about settings to a WPF WebBrowser control. The project also has the ability to produce a report in an .html file that can be viewed through the browser by the clients. Upon comparing the results from both the .html file and the file rendered to the webbrowser, I noticed that the html file is broke when rendered. Some of the borders are missing and some of the colors are not reflecting. Upon doing some research, I found a solution that is to change the meta tag to use the MS edge engine. When I verified my code to dynamically generate the html file, I noticed that the code to set the meta tag uses plain text/html content such as the code below. private void WriteOpenMainTags( string prevFile, string currFile, ref StringBuilder openMaintags) { openMaintags.AppendLine( "<!DOCTYPE HTML>" ); openMaintags.AppendLine( "<html>" ); openMaintags.AppendLine( "...

Good day! Ever wonder how to style your WPF application controls or window with icons where you can choose from several hundreds of icons in a package?

Good day! Here's a simple WPF tutorial on how to close a window in WPF thru button click which applies the MVVM pattern. For simplicity sake, I'll demonstrate by using Menu item with a command to close the window. Start by creating a WPF project that target's the latest framework and add classes for DelegateCommand, MainViewModel and ViewModelBase inside a ViewModels folder. See below project setup. Add the code for ViewModelBase class that implements the INotifyPropertyChanged interface. public class clsViewModelBase : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged( string propertyName) { if (PropertyChanged != null ) PropertyChanged( this , new PropertyChangedEventArgs(propertyName)); } } Next is to add the functionality of the DelegateCommand class that implements the ICommand interface. This class handles the Commands bound to the WPF controls pu...

Hello, I was assigned a new laptop and when I ran several of my WPF applications into this machine, I suddenly noticed that the menu items drop alignment appears to the left instead of right. Since this is a OS setting, we need to change some values in the registry. Open registry editor and navigate to this registry path -> Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows . Change the MenuDropAlignment value from 1 to 0 similar to the picture below. Once done changing the value, make sure to reboot your machine for this changes to take effect. After that, your menu item drop alignment changes from left to right. Output Cheers!
