1
00:00:00,190 --> 00:00:06,140
It's where we left off in the last video we created our data models and in this city where we would

2
00:00:06,130 --> 00:00:14,340
be looking at adding controllers views and taking a general store of the files that help us through

3
00:00:14,340 --> 00:00:16,180
our web programming.

4
00:00:16,230 --> 00:00:16,620
No.

5
00:00:16,620 --> 00:00:20,870
Microsoft gave us quite a few generated files and folders.

6
00:00:20,880 --> 00:00:23,650
They gave us a nice full structure.

7
00:00:23,820 --> 00:00:29,160
It is something like a skeleton or a guidance system if you will.

8
00:00:29,160 --> 00:00:34,110
It is not hard and fast that your project must look like this because as you go along you add things

9
00:00:34,110 --> 00:00:38,250
you remove things so you're full the structure me very from this.

10
00:00:38,370 --> 00:00:43,890
But at the end of the day once you create an NBC project this is the general for the structure that

11
00:00:43,890 --> 00:00:51,060
you get no one to go through the folders we can take a look for and fully appreciate exactly what we

12
00:00:51,060 --> 00:00:52,510
have.

13
00:00:52,710 --> 00:00:55,970
So an upstart you have a few code files.

14
00:00:55,980 --> 00:01:00,000
Those are essential to the actual startup of our application.

15
00:01:00,000 --> 00:01:06,540
They have some free processes and set up routing configuration some identity stuff some bundles for

16
00:01:06,540 --> 00:01:08,280
our styles and scripts.

17
00:01:08,280 --> 00:01:14,700
I'm not going to get into the details of those but we can just have an appreciation of what is an upstart.

18
00:01:15,180 --> 00:01:23,730
If we look at content we see that we have a few CFS files out of the box MVC five comes with bootstrap

19
00:01:24,360 --> 00:01:32,740
kind of integrated and built in so your web application has that bootstrap look and view by default.

20
00:01:32,790 --> 00:01:38,700
You can actually remove it if you wish and you can update it if you wish you can do whatever it wants

21
00:01:38,700 --> 00:01:39,510
it's there.

22
00:01:39,510 --> 00:01:45,480
They also give you another standard since this file which is yours to edit at will.

23
00:01:45,480 --> 00:01:52,050
This practice would have you create another serious file and override styles and bootstrap as opposed

24
00:01:52,050 --> 00:01:53,640
to editing the bootstrap file.

25
00:01:54,000 --> 00:02:00,660
So that's why they would have given you another one where you would add your own custom styles and additional

26
00:02:00,660 --> 00:02:11,360
things to make bootstrap more customized and more personalized in the controllers folder.

27
00:02:11,370 --> 00:02:20,460
We have three controllers and we can deduce from the naming convention that the controller name would

28
00:02:20,460 --> 00:02:25,010
be some word in this case icons and the word controller.

29
00:02:25,340 --> 00:02:29,550
And if you look at all three files you notice that they all have that same form some word.

30
00:02:29,550 --> 00:02:34,080
In this case home and the word manage a controller.

31
00:02:34,080 --> 00:02:39,870
So if you're going to create a new controller you should have whatever you're calling it and ending

32
00:02:39,870 --> 00:02:43,650
with the word control in tabular case.

33
00:02:44,790 --> 00:02:46,950
Funds those are generated.

34
00:02:46,950 --> 00:02:51,560
Those are coming with bootstrap because throw the internet.

35
00:02:51,630 --> 00:02:56,090
Not every computer is going to have the funds that you would like to display.

36
00:02:56,120 --> 00:03:04,290
So it's always good at least in modern day web development to include the funds file with your project

37
00:03:04,350 --> 00:03:09,090
so that the server loads the funds as opposed to the client machine.

38
00:03:09,150 --> 00:03:11,130
So that's that's why that's is there.

39
00:03:11,190 --> 00:03:15,490
I would advise you not to eat it though unless you have a game plan.

40
00:03:15,510 --> 00:03:21,710
We went through modules how we saw where we have different class files and we added or the needs of

41
00:03:21,710 --> 00:03:23,350
these entities model.

42
00:03:23,370 --> 00:03:26,040
So we have our approach star database

43
00:03:28,950 --> 00:03:35,190
where the scripts folder which plays host to a bunch of scripts.

44
00:03:35,200 --> 00:03:42,790
Most of the G query scripts that are needed to complement or bootstrap scripts.

45
00:03:42,790 --> 00:03:50,710
We also have moderniser response which help with responsiveness and the backwards compatibility for

46
00:03:50,830 --> 00:03:54,380
more Isham of stuff for older browsers.

47
00:03:54,610 --> 00:03:58,720
So all of this stuff comes prepackaged with the web projects.

48
00:03:58,720 --> 00:04:00,790
You don't have to add these things manually.

49
00:04:01,320 --> 00:04:10,600
All right so here we have or views folder which plays host to our res of you files with the extension

50
00:04:10,740 --> 00:04:12,610
thought C S HDMI.

51
00:04:12,730 --> 00:04:17,530
I guess it seeing C sharp finished him combined that's exactly what Razer is.

52
00:04:17,530 --> 00:04:25,690
No I wanted to appreciate the correlation between the folder names here in the views and the names of

53
00:04:25,690 --> 00:04:26,920
the controllers.

54
00:04:26,950 --> 00:04:31,980
So we're going to look at the home controller and appreciate that correlation.

55
00:04:31,980 --> 00:04:37,350
So we have a home controller which is a s file and a CSI file is just the class file.

56
00:04:37,360 --> 00:04:47,170
As you see it's really just a class in purging from base class called controller and in it it has functions

57
00:04:47,360 --> 00:04:52,220
methods procedures whatever keyword you use used identify them.

58
00:04:52,240 --> 00:05:02,050
It has those they all return some type of action results and the return value for an action result is

59
00:05:02,060 --> 00:05:10,780
you know what this is doing is establishing that for every method you have here you should have a corresponding

60
00:05:10,900 --> 00:05:14,500
view file and that is what this returns.

61
00:05:14,500 --> 00:05:23,380
So when you send a request for index from the home controller it will search through the view folder

62
00:05:24,190 --> 00:05:31,060
and then look for a follow the corresponding name or home and then it will look for a controller with

63
00:05:31,360 --> 00:05:41,730
a view look for a view with the corresponding function name index and then it will return it.

64
00:05:41,750 --> 00:05:49,130
So that means if you have a method here and you have no corresponding file in a corresponding folder

65
00:05:49,340 --> 00:05:52,780
then you will get something like a forum for error.

66
00:05:52,910 --> 00:05:54,750
What we will get into that is an explorer.

67
00:05:54,770 --> 00:05:57,190
All of that in a few minutes.

68
00:05:57,680 --> 00:06:00,370
So just take a look at index really quickly.

69
00:06:02,680 --> 00:06:09,650
Now our index file I want wanted to appreciate that it has purely HDMI all things in it.

70
00:06:09,650 --> 00:06:17,210
Apart from this section which is preceded by this at sine once you see an outline that means you are

71
00:06:17,300 --> 00:06:21,940
able to superimpose C sharp into your HMO.

72
00:06:22,490 --> 00:06:23,210
All right.

73
00:06:23,320 --> 00:06:32,420
Was a C issue in the file so it's allowing a lot of bit of C sharp and it is merging it with HMO and

74
00:06:32,420 --> 00:06:42,880
I just do a quick example of C sharp in this as a school vector statement so I'd sign if a limit is

75
00:06:43,320 --> 00:06:43,690
3.

76
00:06:43,690 --> 00:06:50,370
This is just my way of example just to show you how appraisal works that actually allows me to create.

77
00:06:50,490 --> 00:06:52,200
Sorry of syntax error.

78
00:06:54,240 --> 00:07:00,770
It allows me to actually superimpose C sharp code right here in my age.

79
00:07:00,930 --> 00:07:06,660
So that is the relevance of my C issue or reason of your file.

80
00:07:06,660 --> 00:07:12,450
Another thing to note is that we don't have that traditional skeleton on I thought it's a skeleton where

81
00:07:12,750 --> 00:07:15,350
every Asian of beach should start with not type.

82
00:07:15,750 --> 00:07:19,680
And our head and our body types we don't have that here.

83
00:07:19,680 --> 00:07:21,690
None of these files have.

84
00:07:21,740 --> 00:07:29,110
That's because they are all inheriting from what we call a lake of fire and we get to see the little

85
00:07:29,130 --> 00:07:30,660
fire in a few.

86
00:07:30,660 --> 00:07:37,500
But what I really want you to see and appreciate is the fact that each file here the name corresponds

87
00:07:37,500 --> 00:07:42,560
with the name of the method that is it the controller.

88
00:07:42,570 --> 00:07:51,360
All right so once you have a method name once again you need to have a corresponding you file in a folder

89
00:07:51,420 --> 00:07:56,680
which has a corresponding name to the controller all right.

90
00:07:57,240 --> 00:08:04,480
So let's just take a tour and finally Press five the moment you've all been waiting for.

91
00:08:04,590 --> 00:08:09,310
So we'll grows so it may have taken a while but once you're here we want to take a look.

92
00:08:09,330 --> 00:08:18,220
I told visual studio and is not at NBC are aiding us to create a fully functional data driven Web sites.

93
00:08:18,220 --> 00:08:21,500
Now this is our index speech.

94
00:08:21,540 --> 00:08:28,320
Cardinal rule for me when it comes to web design is that all pages should be called index once it is

95
00:08:28,440 --> 00:08:30,160
the intended Holmby.

96
00:08:30,220 --> 00:08:36,420
All right now our index page if you look at this and we look at the code you see the correlation between

97
00:08:36,420 --> 00:08:40,330
what is here as contents and what was on the page.

98
00:08:40,380 --> 00:08:45,640
We'll also see that we have a little bootstrap theming going on we're using the bootstrap love bootstrap

99
00:08:45,660 --> 00:08:51,930
buttons even the funds is coming from bootstrap everything's integrated bootstrap.

100
00:08:52,210 --> 00:08:59,480
Now I want us to also appreciate that this is loading from local horse it's not loading from your of

101
00:08:59,480 --> 00:09:07,830
file sets as it would be if you were building a regular HMO page visual studio is actually conjuring

102
00:09:08,280 --> 00:09:15,210
a session of I S express as is short for internet information services.

103
00:09:15,360 --> 00:09:23,220
So it is conjuring magnified version of that and using it to emulate a web server experience when you

104
00:09:23,220 --> 00:09:27,240
go into e-book mode which is when you pressed a five.

105
00:09:27,410 --> 00:09:33,920
Now if we browse freeform we see that this is already home we keep a boat and we see that link change.

106
00:09:34,050 --> 00:09:40,390
So no we have both the host and airport number may differ from mine.

107
00:09:40,560 --> 00:09:50,010
We see form we see a boat now remember or controller name was called Hope so whatever the name of the

108
00:09:50,010 --> 00:09:58,320
fund trawler is that is what will appear and this will be followed by the name of the view that we have

109
00:09:58,500 --> 00:09:59,390
requested.

110
00:09:59,400 --> 00:10:05,810
So in fact contact you see a similar change home slash contact.

111
00:10:05,850 --> 00:10:06,270
All right.

112
00:10:06,530 --> 00:10:07,800
And I will go back to home.

113
00:10:07,800 --> 00:10:12,940
It's going to load index anyway so it doesn't need to indicate anything else.

114
00:10:12,960 --> 00:10:17,550
Now we're going to go back to visual studio and make a few changes.

115
00:10:17,730 --> 00:10:20,660
Back in Visual Studio I'm just going to come out of e-book mode

116
00:10:26,520 --> 00:10:29,740
now we're going to add a new view.

117
00:10:30,880 --> 00:10:36,030
So I'm just going to take two steps though in public.

118
00:10:36,570 --> 00:10:44,110
You know our return type once the action resolves and then I'll see test review

119
00:10:48,060 --> 00:10:56,520
opened up for her or girl abuses and then we know that we have to return view as is the value at the

120
00:10:56,520 --> 00:11:01,490
very least that's our method stub is expecting.

121
00:11:01,880 --> 00:11:02,420
No.

122
00:11:02,750 --> 00:11:11,300
If I run in debug mode once again and then attempts to rose to this view you should get an arrow because

123
00:11:11,300 --> 00:11:14,480
there is no corresponding file in this folder.

124
00:11:14,870 --> 00:11:19,370
So we'll just run that experiment and then we'll build and go ahead accordingly

125
00:11:22,210 --> 00:11:24,170
now that we have or what.

126
00:11:24,170 --> 00:11:30,250
Up up we can follow the same path convention that we're used to.

127
00:11:30,620 --> 00:11:37,030
So we can just see a slash home since that is the controller that we just added that view to.

128
00:11:37,220 --> 00:11:45,120
And then I'm going to write in the name of the new added you which is test you press enter and then

129
00:11:45,120 --> 00:11:49,360
we're greeted with this very unattractive page.

130
00:11:49,470 --> 00:11:55,680
But then if we take the time to appreciate what it is seeing just letting us know that the view by this

131
00:11:55,680 --> 00:12:01,510
name was not phoned in any of the locations that were searched.

132
00:12:01,530 --> 00:12:07,020
So we see that it looked in the views folder it looked in the corresponding home folder and then they

133
00:12:07,020 --> 00:12:17,840
didn't find any files that would possibly could possibly have passed as a view file all right.

134
00:12:18,230 --> 00:12:21,960
So that is that kind of URL that we would get.

135
00:12:22,070 --> 00:12:31,350
Having not made the hard adjustments to our projects now back in Visual Studio we still have a bit of

136
00:12:31,350 --> 00:12:33,690
work to do to get this view over and running.

137
00:12:34,560 --> 00:12:37,310
We already created the method stop here.

138
00:12:37,320 --> 00:12:39,700
What we want to do is get the file over here.

139
00:12:39,780 --> 00:12:50,380
You can rightly click and go to view and then give it the name that we know you want and that will be

140
00:12:50,380 --> 00:12:54,420
test you.

141
00:12:55,120 --> 00:12:59,550
And then you'll see a bunch of other options here we don't need to worry about template model class

142
00:12:59,550 --> 00:13:00,520
just yet.

143
00:13:00,520 --> 00:13:04,310
We don't want to take this but then we'll see something here about Leo.

144
00:13:04,310 --> 00:13:09,970
Page I mentioned Leo pages earlier but we still have not made it to look at the LEO page.

145
00:13:09,970 --> 00:13:15,530
But I will just leave this blank for no ad

146
00:13:19,260 --> 00:13:22,650
and then it goes through this thing called scaffolding.

147
00:13:22,650 --> 00:13:28,650
I know we have our newly created view and it's quite a simple page like we said it's almost a bare bones

148
00:13:28,670 --> 00:13:36,240
each journal page that is capable of having some amount I'll see sharp text in it you get the title

149
00:13:37,170 --> 00:13:39,240
here in this variable.

150
00:13:39,240 --> 00:13:42,380
So it's also generating all of this.

151
00:13:42,630 --> 00:13:53,270
And I'm just going to write a v tag that says hello world and I will give it's one of those famous bootstrap

152
00:13:53,270 --> 00:13:54,260
classes.

153
00:13:54,270 --> 00:13:55,000
Class.

154
00:13:55,650 --> 00:13:56,300
Let's see.

155
00:13:56,310 --> 00:13:58,910
Text Nash in full.

156
00:13:59,170 --> 00:14:07,390
So we should get blue text when we render that of course we can control a shift and B are able to build

157
00:14:07,420 --> 00:14:09,130
and build solution.

158
00:14:09,130 --> 00:14:15,450
Either one works just to ensure that we have no syntax errors in our code.

159
00:14:15,670 --> 00:14:19,930
We also see that or you file is created over here.

160
00:14:20,200 --> 00:14:25,720
So if you go back into debug mode and then we've gross to test you then we should be greeted with a

161
00:14:25,720 --> 00:14:31,420
page with an issue tag with this generates a text as well as a text that we've just added

162
00:14:34,690 --> 00:14:36,460
know that we've made that adjustments.

163
00:14:36,490 --> 00:14:45,520
We'll just come back to this age refresh or maybe you press F5 from visual studio then it would have

164
00:14:45,520 --> 00:14:53,770
loaded to this speech we see here that we have or H2 tag printing this and our whole world looking blue

165
00:14:53,890 --> 00:15:03,770
because we've put on the bootstrap class for text cache info so we can just go MacOS of evil mode.

166
00:15:03,860 --> 00:15:07,220
And now we know how to add more views.

167
00:15:07,220 --> 00:15:16,360
So our project once again we go to the controller and we make sure that there is a method stub that

168
00:15:16,360 --> 00:15:21,590
has a corresponding name with the view that we want to get to.

169
00:15:21,850 --> 00:15:22,210
All right.

170
00:15:22,630 --> 00:15:29,020
Now I mentioned the little webpage more than once and I'm not going to give you a quick tour of what

171
00:15:29,020 --> 00:15:30,700
is in the little piece.

172
00:15:30,730 --> 00:15:41,110
Essentially the page is a generic reusable template for your pages you can have more than one layouts

173
00:15:41,500 --> 00:15:48,130
and a case for having more than one fields would be like if you have a system that has a customer facing

174
00:15:48,130 --> 00:15:55,040
side and an admin portal then a portal probably looks differently from the customer facing one.

175
00:15:55,240 --> 00:16:00,250
So you can have a little ad for the IP inside and the layout for the customer office inside and then

176
00:16:00,250 --> 00:16:06,750
that would reduce the need to do the repetitive stuff over and over and over.

177
00:16:06,760 --> 00:16:12,180
It's just of meaning to the scripts and doing the HMO skeleton every time.

178
00:16:12,180 --> 00:16:12,490
All right.

179
00:16:12,580 --> 00:16:19,170
So that is why you have such a very scaled down version of a view file over here.

180
00:16:19,270 --> 00:16:28,720
But then in the shared folder under views you have a layout that see this ECMO file and you go into

181
00:16:28,720 --> 00:16:34,750
this and you're not bombarded with a bunch of HD IMO but if you take a step back and you just go through

182
00:16:34,750 --> 00:16:42,220
it you see that it's regulated stuff that it's HMO ever hit thugs inside that we have some metal declarations

183
00:16:42,370 --> 00:16:50,500
or char sets and for Responsive Web Design purposes these are bootstrap required at the very least.

184
00:16:50,500 --> 00:16:54,880
We see here where the title is being set dynamically if we remember.

185
00:16:54,910 --> 00:17:01,330
So if we go back to testify we see that here we set the view bagged up titled eat test you in the labeled

186
00:17:01,330 --> 00:17:09,040
file it is changing with each page that the test render and then the static part of it which is my is

187
00:17:09,090 --> 00:17:15,640
the ultimate application since we're doing a school management system of change that the school management

188
00:17:15,790 --> 00:17:17,740
system right.

189
00:17:18,530 --> 00:17:21,410
And then some of the declarations here.

190
00:17:21,500 --> 00:17:24,650
These functions are C sharp functions.

191
00:17:24,650 --> 00:17:31,970
So we see here are at sign signifying that we're superimposing some C sharp and then styles is a static

192
00:17:31,970 --> 00:17:40,610
class which is calling function called render which is then passing in some pharmacies which if you

193
00:17:40,610 --> 00:17:49,970
look at the HMO that gets generated from this you will see the actual code linking all of our files

194
00:17:49,970 --> 00:17:52,130
from our content folder.

195
00:17:52,130 --> 00:17:53,060
All right.

196
00:17:53,900 --> 00:17:55,450
We'll get into that right now.

197
00:17:55,490 --> 00:17:57,770
Later on we'll explore that in more detail.

198
00:17:57,770 --> 00:17:59,990
I just want you to appreciate what you're looking at.

199
00:18:00,500 --> 00:18:02,270
And then we render some of the scripts.

200
00:18:02,270 --> 00:18:08,620
In this case we're really rendering just moderniser does the testing go ahead of everything else but

201
00:18:08,630 --> 00:18:16,400
then below that is where we're rendering the other scripts such as the G query and bootstrap and setting

202
00:18:16,400 --> 00:18:17,980
some parameters.

203
00:18:18,800 --> 00:18:25,660
No if we just scroll through and look at it we see Buddy we see here we're adding enough bar bootstrap

204
00:18:25,680 --> 00:18:26,230
style.

205
00:18:27,050 --> 00:18:27,820
All right.

206
00:18:27,830 --> 00:18:29,730
We see here that we have an action link.

207
00:18:29,750 --> 00:18:37,790
So we have an object but each GMO has a function called Exon link which is taking a few files so a few

208
00:18:37,790 --> 00:18:41,080
values as parameters.

209
00:18:41,080 --> 00:18:41,510
All right.

210
00:18:41,870 --> 00:18:50,570
So here I'm just going to change application name as I'm sure we remember on our page you see application

211
00:18:50,570 --> 00:18:53,040
name coming up every time on each page.

212
00:18:53,060 --> 00:18:57,680
And who would want to say application names would actually want to give its the name it should be.

213
00:18:57,680 --> 00:19:06,710
So this would all management system and then we have enough bar poem about contact.

214
00:19:06,720 --> 00:19:14,790
If we look here we see that this is our enough bar and we have each of those links home uploads contacts.

215
00:19:14,940 --> 00:19:21,910
Now we just created a test view you'd like for it to be in the nav bar that we can browse through it

216
00:19:22,130 --> 00:19:23,160
at will.

217
00:19:23,180 --> 00:19:26,850
So I'm just going to control the.

218
00:19:26,990 --> 00:19:35,790
And that duplicates the line and then we can just modify this so to say test you all right.

219
00:19:36,050 --> 00:19:39,660
So the first block of text speaks to what it is.

220
00:19:39,680 --> 00:19:43,810
What is it you want to print on the enough bar.

221
00:19:44,000 --> 00:19:49,790
The second block speaks to the actual method that it should look for.

222
00:19:49,820 --> 00:19:54,040
So remember in the controller we want to look for the method by the name test.

223
00:19:54,100 --> 00:20:00,830
You notice there's no space here because we don't put spaces in our method names but we have to see

224
00:20:00,830 --> 00:20:07,110
it as it is here and it is not case sensitive if you want to use lowercase here or use.

225
00:20:07,110 --> 00:20:08,230
Look is here.

226
00:20:08,330 --> 00:20:13,780
Are you grossly with lowercase we will all be the same thing over outputs of space with this one because

227
00:20:13,780 --> 00:20:21,500
we wouldn't want to print the kind of case test view or user so we print what we want to or use it here

228
00:20:22,760 --> 00:20:25,220
and then the controller is home.

229
00:20:25,250 --> 00:20:29,360
So this last parliament speaks of the control.

230
00:20:29,390 --> 00:20:37,400
So if you take a careful look at home you would see that we're printing home in our enough bar here.

231
00:20:38,570 --> 00:20:44,440
However it is linking to the index method inside of our home controller.

232
00:20:44,570 --> 00:20:51,520
So it is linking to our index method in our own controller which then search for the.

233
00:20:51,550 --> 00:20:56,810
Searches for the view called index and then renders that over.

234
00:20:56,810 --> 00:21:01,400
We're telling the user it's home all right.

235
00:21:02,360 --> 00:21:09,150
And then as we go down in our layouts we see here in our body contents give.

236
00:21:09,290 --> 00:21:19,000
That's where rendering body so render Buddy really speaks to the actual rendering of the C.S. Isham

237
00:21:19,190 --> 00:21:27,590
view file inside of this entire layout which is why all of them are being rendered we find of bar and

238
00:21:27,590 --> 00:21:37,660
with a filter we saw our filter had our copyright sign the year and some random text which was up in

239
00:21:37,730 --> 00:21:40,150
generics in my is done on its application.

240
00:21:40,250 --> 00:21:46,130
So since we're changing out all of those occurences of my speed on this application we want to ensure

241
00:21:46,130 --> 00:21:54,790
that all school management systems I just looked at that and I'm displacing it here and then I can control

242
00:21:54,800 --> 00:22:02,330
shift and V and build and make sure I have no syntax errors and then we can go back into debug mode

243
00:22:02,480 --> 00:22:11,120
and see all of or changes a person at five to interview so when our page loads we see here that we have

244
00:22:11,250 --> 00:22:16,560
of all of our changes reflecting we have split management system printed here instead of application

245
00:22:16,580 --> 00:22:24,930
name we have artists view no Avatar enough bar and we have our filter reflecting or age.

246
00:22:25,010 --> 00:22:31,520
So if we want to start changing contents you know if it then dude wouldn't want to have a school management

247
00:22:31,520 --> 00:22:37,220
system which is being printed over there we'd want to change the content and so on and we'd have to

248
00:22:37,220 --> 00:22:45,540
go into our view files keynote the content and start putting in all of our custom content for each page.

249
00:22:45,550 --> 00:22:45,890
All right.

250
00:22:46,130 --> 00:22:55,910
So I hope you appreciate all views and controllers work and hope they'll tie back to the LEO page and

251
00:22:55,910 --> 00:23:02,820
how you can effectively go about adding more content and functionality to your Web site.

252
00:23:02,840 --> 00:23:03,830
See you again next time.
