Hello world.
I'm talking about selecting feet and inches using a scroll bar in C#.
I have a program.
I wrote previously.
That selected the number of inches.
We have hsbInches.
And it has a...
Minimum of 0 and a Maximum.
of 100.
And that's enough to select the height of any person.
And I also have
both Small Change.
and Large change.
set to one.
And I currently have given it a value of 50.
And I also have.
lblInches where I can display the inches that are selected ...
on this scroll bar.
When I double click on the scroll bar.
I open up my code.
Previously,
I displayed the inches just giving the inches,
but instead of 60 inches I would like it to say.
5 feet 0 inches or instead of 66, 5'6 inches.
So I'm going to just comment this out.
Instead of just destroying it and deleting it.
I'm going to use a variable.
So I'm going to start with int.
feet
Is equal to
hsbInches.
. [dot] Value.
Divided by 12.
And another integer inches.
Is equal to.
The remainder.
Then I'm going to
lblInches.Text
Equals.
A null string.
Feet.
+ [plus]
Inside quotes,
a single quote.
Plus.
Value of inches.
Plus
Now, I want the inches symbol,
" so it's
Inside these double quotes.
I'm going to have a backslash.
and another double quote.
And don't forget the semicolon.
So let's run that and see what we've got so far.
And I have four feet 5 in.
And for 100, 8 feet 4 in.
And all the way down here.
where the value is 0, we have 0 feet 0 inches.
Here in the middle,
4 feet 0 inches. So there's a couple little ...
things to note here.
One is this backslash, \, is an escape.
Character.
It says to ignore.
Meaning within C#.
of a double quote,
and display it just as it is.
And then this is kind of hard to see but inside the double ...
quotes we have the single quote.
And we start with a null string, because we have to put a string value
in as the text for lbl inches that means we have to start ...
with a string of some sort.
Previously we had said "Inches equal"
that gave us a string, but now I just want to display ...
the feet and inches and so we just have that.
And if we wanted we could have two labels and display
both the
Total inches, and the feet and inches.
But I'll leave that as an experiment for you to try.
And that's it for now.
