So we're going to be continuing periodic table example.

It's not what happens.

We can make.

There is the first thing I want to do is replace the string grid with a draw grid.

Now if I press if one on the string grid it will bring help and we'll see that string grid actually

descends from Piedro grid.

Now string grid introduces the cells property which if we look at the on create create event we can

see that basically we are storing the structure of the pivot table in the cells property which is less

than ideal it would be nice to have this in a separate class which would make it far more usable so

that we could have you know the monkey version or a web based version or we might have

a different version which uses a different control altogether.

So basically the first thing going to do is create a new class and we get to do that in the elements.

So let's let's do that.

So let's create a new periodic table class

chicken and

t elements

of public and private sections and selects So we're going to need to create here

and we're going to need to create apps

on the table.

And in the form create

you need to create a periodic table whatever that entails.

And

to create.

So basically we want to store the structure of the table.

So

I make it as an array of

number of columns.

Times the number of rows and we make it of element

and of course we need some way of getting that out.

So we have a

function called element which takes a

a column in a row with integers

into Juda

and returns and the element

to be lazy or doing any range checking.

So that's fairly simple.

Now we also want to load elements and build it from the CSC for

farming strength and when you see the elements from somewhere so

OK so Bankia

and

I just copy and paste all that

OK.

And basically I'm going to copy this for now rather than rather than shifting it

to show that there aren't any directory.

But we need everything else

this becomes

a file name

call the grove

and installed element

and the top number.

So it shouldn't theory be a periodic table constructed.

So we were just doing the same as before except we're getting from a specified filename and we're filling

in a an array.

Now the array is initialized will be NULL to begin with.

When the class is created.

So anything to the complete code will be full array.

OK.

So the next step will be to start using our pivot table rather than the

than having had coded.

This is run and confirm

Privett is just true.

Strike appalling that again and compiles doesn't run.

It runs

OK.

So if we scroll down the easiest thing to replace will be the silica cell which fills when it runs fills

a little what is it called Peenemunde details.

So rather than getting the element from the string grid.

So period table dot elements and

to go plus one because the strict grid is zero based and here table class is the array start at one

Ravinder.

That's the top number to all.

So it is not.

And that line.

So that should be select cell code so let's run that and see if that still works.

Yes it does.

So we're now getting details from the perfect table glass

and next thing we want to update is this string grid draw a cell so what I'm going to do is I'm going

to get rid of simple and Tullock number

have an e.

And I love it.

So elements

like OK.

So now it's going to use the details from E rather than.

So got know

in fact we don't even

at all surfie.

But he will tell.

There

is no

and take that and extend it down to the bottom

so if it isn't all that is to say in the given Zelle there is no element or we're going to be doing

is drawing a white background.

Very exciting.

But if it contains an element we're either going to highlight it or have so many green cell Kellow

and dot number you know simple simple simple.

Okey dokey.

So basically it was pretty much the same as before except when they're now getting stuff from the elements

and making sure it's not nil.

And if we run that it looks exactly the same as pretty impressive.

But anyway now what we can do is we can get rid of all that code

for the directory that needs nothing else.

And if we run this it still works.

And the next thing we want to do is change our strength grid to a T Droguet.

So what I'm going to do is I'm going to personally have 12 or Ashokan and reichlich and go viewas takes

only 12 and I'm going to change our street grid to a draw grid.

OK.

So we need to fix a declaration and

and it looks like symbols not quite wide enough let's make it at what.

OK.

So that's pretty much every working of the periodic table and using the grid and eliminating the cells

properly.

So using the cells property any way any more which allows us to use the strenger sorry the drill grid

and the last thing we might want to do is

rename our last string grid to

a court to agree to a periodic table grid.

And that compiles indeed.

OK.

So that's a little bit tidy.

So let's say all that.
