Blazor Edit Form and Validation

-

     For a class project I'm working on in a secure coding class I wanted to find a way to safely validate form data as to not send malicious values to our API or our database. I was working out how to do this in Blazor, and found the handy EditForm component. It allows you to enter a type of model you'd like the form to build, and in that model we can specify if the form is required and what type of data is allowed in.

 

    In this example we have a couple required fields and we don't allow any special characters into our fields. We also only allow a certain length of string as our input, and simple error messages are displayed when invalid data is passed. When proper or improper data is passed to our form, it looks like this:

API's in C#

      There is a lot here to take screen shots, but the code is all on my GitHub here if you'd like to follow along with this post.       My wife teaches sixth grade, and lately I've been thinking about an application I could build her to help manager her classroom and motivate the students to improve on the skills they've been struggling with. The concept is to turn a classroom into a game of Dungeons & Dragons, except the skills are in things like math and reading. Students would answer questions instead of rolling dice, and can then add their skills to their results so they can earn experience and rewards. Originally I was going to build this in FastAPI but I thought .NET Core would be better for setting up models and working with a database.     I started by setting up my models in a shared class library project, and I added a Classroom class for tracking classes of students, a Student class for tracking the stats of students and a Logs class to keep track of how a

Using WebRTC to build a videophone in React and TypeScript

-
 Recently I had the opportunity to spend more time learning React, as well as Redux and a bit about WebRTC. I was prototyping a website that allows you to make video calls to other users, and I thought it was really cool how out-of-the-box WebRTC is. I also used TypeScript, even though I had some trouble in the past with React-TypeScript applications, and it went pretty well. There was some finicky things and it required me to learn the types of objects I had never used before, but overall I think it went pretty well.   The server is built with express, and uses socket.io to emit the web-rtc requests. There is no authentication or authorization, I was mainly focused on showing that I could make a video call.It uses Redux to handle state management, which was a bit tricky in TypeScript and felt like I was writing a lot of repeat code, but it got the job done better than it would have without it. Ultimately this project ended up being put on the backburner as my team turned to Flutter in

Reviewing WPF and MVVM

 I've been working in WPF (Windows Presentation Foundation) a lot lately. WPF is a great way to build a Windows desktop application, it's been around for many years and is very mature compared to UWP (Universal Windows Platform) which is a similar tool for creating desktop applications. It's not the newest, shiniest tool but it is definitely a great tool to be aware of. A while back I built a simple WPF program that worked with a .NET function library that did very simple distance calculations, and I decided to review that before really getting into more advanced concepts. When the program runs, it looks like this:   It's nothing too fancy, but it will show travel time, rate of travel and distance traveled over time. It also allows an excel spreadsheet to be inputted and it will run many calculations and then update the spreadsheet. The layout here is primarily built using the XAML grid, a staple of any WPF application. The grid specifies how many rows and columns the g
