1.6	Hello World!
I'm talking about creating a custom form in C#.
I want to have the user select days of the week that they can meet.
And I have a menu item, getDays.
All the checkboxes with days of the week would take up too much room here.
So I'm going to put it in a separate form.
From the menu I select project, Add Windows form.
Select Windows form, and then I'm going to name this form days.
That's very important to name that here.
And then we click add, and I now have two forms.
I have my main form, form one,  and I form days.
For form days I'm going to add, uh...
Monday, Tuesday, Wednesday, Thursday, and Friday.
I need a label to tell them
Please select all the days you can meet.
And I'm going to have a button that says
[Let's get rid of that.]
And a button that is going to be named [text]
&Okay and has the name  btnOk
My code...  I'm going to put the words Monday, Tuesday in a minute.
The code for btnOK is going to say this dot hide.
and the word "this" refers to whatever form it's in.
So in this instance, "this" refers to form days.
And go back to our form one , and...
Double click on  Get Days, in the code, I'm going to and paste this in
And then explained it.
So we have form days, that we named it that when we created it.
But the instance is called frm,
and that's a new instance of that form that we created.
I'm going to show it dialog,
because I want to wai, and after the user selects days, and then
Says okay, I want the code to execute from this point.
I have a string s that's a null string.
Then I'm going to use a for each loop
to look at each control in frm set of controls.
If the control is a checkbox
I'll create an instance,
a new instance of a checkbox called chk.
if chk is checked
then s equals s plus
whatever the text on that checkbox is.
And a blank space,  so there will be a space between names.
When this loop ends,
I store the result lblDays.text
So, let's run that and see what happens. OK...
Here's my program, and right now it says days are none selected.
I click get days,
and this form appears that says form days
and I check Monday, Wednesday, Thursday
and click OK.
And as soon as I do that
we see the words Thursday, Wednesday,  Monday
appear on our form.
The main form: form1.
I know they're not in the right order
And that's another problem that you could solve
by using an array of Boolean or something like that,
And  then putting it together.
But  that's it for now.
