Hi!
In today's video, we are going to talk about how to get user input from the keyboard. In Windows Forms apps, there are events called KeyPreview, KeyDown, KeyUp, and KeyPress events and they all work in their own unique ways. I have scowered the internet for answers for hours and there is no good video out there covering this subject, so I made one to solve that! Today we make a simple C# windows forms app and I explain the difference between each type of function and how they operate within Visual Studio!

This is great for anyone starting. You should build onto this and make a mini project where u add features to add per video so at the end of the series or however you wanna call/do it, you and the viewers who follow along have something :D

@Lunar-rb9um 2 года назад

What if you wanted to use more than 1 character? For Example: 'S A E' would trigger a button

@ShaunHalverson 2 года назад

You would map those keyValues to the buttonYouWantToClick.performclick() methods. So if you wanted to click the same button with S A or E, you would say "if these keyvalues happen, click these buttons"

in window constructor, after InitializeComponent, enable KeyDown to the window: this.KeyDown += OnKeyDown; and create OnKeyDown method to handle pressed keys.

@MrJohnRBX 2 года назад

do you know how to use a keyboard key in background?

@ShaunHalverson 2 года назад

I’m not sure what you mean? Can you clarify a little?

@MrJohnRBX 2 года назад

@@ShaunHalverson For example, pressing a key without having to open the program, pressing it in the background, is that understood? 😜

@ShaunHalverson 2 года назад

@@MrJohnRBX Yeah understood lol, I am unsure how to do that without tabbing into the program somehow. Since these things seem to operate based off “focus” on the controls. If it doesn’t have focus at all in the program, I am unsure if you could get it to work. Did you attempt it after finishing what was done in the tutorial?

@MrJohnRBX 2 года назад

@@ShaunHalverson I did it but I want to try something different, I am making a text to speech application and I wanted to do it so that I could write in the application from the background :P
