Hello World!
I'm talking about how to use the text box in C#.
I've  started a new project
And from my toolbox going to add
a text box
for someone to enter their name.
so I need a label
and this is going to be instructions
so let's name that
lblInstructions
[typing] and...
the  text is going to say...
"Please enter your name."
and the text box
is going to be called txtName
and I'm going to leave the text empty.
It's very important to note that labels
are for displaying information,
and text boxes are for entering information.
the, if I double-click on the txtName,
the text change event is the default event.
So let's say Text
equals "Hello
Notice I put a space befor the quote otherwise the name
and the hello will be run together.
txtName.Text
And let's run that, there's a little problem ...
Oh, we don't use an ampersand, we use a + to concatenate, let's run that.
And the problem is that every time we type a letter,
it's going to say "Hello Ro",  "Hello Rob" and so on .
and if we hit enter,  nothing happens.
I'm going to comment  this out,
and go back and add a button.
and I'm going to name the button btnSubmit
and make the text btnSubmit
And instead of saying hello here,
I'm  going to say hello when we hit the  submit button.
and if I run this, and I type in Robin
and hit enter, nothing happens.
but when I hit btnSubmit, it says "Hello Robin"
A lot of users are used to pressing enter
to end that, so let me show you how we can make that happen.
I'm going to go back and select my form, you can tell it's selected: it has the handles.
and way up at the top there's an accept button
and going to pick btnSubmit as the accept button.
And what that does is when I press enter button that will be executed.
So here's my running application type in Robin,
I press enter and it says "Hello Robin"
And  that's it!
