1
00:00:00,120 --> 00:00:05,700
So in the spirit of what we're doing, how to utilize these windows if we are using this, you shot.

2
00:00:05,880 --> 00:00:14,180
So in this movie I will be using this message function to generate a graphical user interface message

3
00:00:14,430 --> 00:00:15,230
small pop up.

4
00:00:15,930 --> 00:00:18,660
So before that I was talking about the data types.

5
00:00:18,870 --> 00:00:26,040
So here you can see unmanaged type in Windows abuse and C language type for running.

6
00:00:26,040 --> 00:00:28,620
C, you need to use these data types.

7
00:00:28,950 --> 00:00:31,870
But C-sharp is manager correctly.

8
00:00:32,000 --> 00:00:36,780
That means this C-sharp chord is controlled and managed by ACL.

9
00:00:37,350 --> 00:00:42,210
So if you if there is no ACL around this system, there is not Darknet installed.

10
00:00:42,540 --> 00:00:45,320
You can't run these C-sharp binaries.

11
00:00:45,330 --> 00:00:51,120
So you need to have this here are loaded to load our to run our binaries.

12
00:00:51,960 --> 00:00:55,410
So in order to access these functions, you need to.

13
00:00:58,460 --> 00:01:00,190
Well, import this idea first.

14
00:01:00,350 --> 00:01:05,330
So if you go down to this function, you will see the user that you do not be.

15
00:01:05,660 --> 00:01:10,610
So this function message box resides in this audience.

16
00:01:10,610 --> 00:01:13,190
So ladies are exactly seem like executives.

17
00:01:13,460 --> 00:01:14,990
But we cannot exclude them.

18
00:01:15,020 --> 00:01:17,480
We can only load functions from this.

19
00:01:17,810 --> 00:01:27,440
So many processes use this data so that the analysis, many processes can access the functions in the.

20
00:01:28,750 --> 00:01:32,710
One day without having the multiple number of copies.

21
00:01:32,950 --> 00:01:44,200
So I how in process accessing this message box function without having pen it so one day you can answer

22
00:01:44,200 --> 00:01:46,080
these functions for many process.

23
00:01:46,090 --> 00:01:48,340
So that is the advantage of this reader first.

24
00:01:50,260 --> 00:01:54,370
So here you can see the manager typing the shot for why this is not why.

25
00:01:54,730 --> 00:02:00,100
And you can see in the pointer and write in in 16, etc..

26
00:02:00,100 --> 00:02:03,100
So here you can see all of these, uh.

27
00:02:05,280 --> 00:02:06,130
Manage it better.

28
00:02:06,750 --> 00:02:09,510
So one thing you need to notice is match box.

29
00:02:09,600 --> 00:02:16,740
WWE stands for white character for the Unicode and you can also see message box here that is for as

30
00:02:16,740 --> 00:02:17,220
question.

31
00:02:17,880 --> 00:02:22,020
So you need to pass the strings as a unicode once.

32
00:02:26,080 --> 00:02:33,250
We need to import a namespace card system that runtime not interrupt services.

33
00:02:34,560 --> 00:02:38,040
From this, we need to import the functions from here.

34
00:02:38,310 --> 00:02:43,770
So before that, now in my class I can to brackets the import.

35
00:02:44,970 --> 00:02:46,790
I need to specify the bearer name.

36
00:02:46,830 --> 00:02:52,560
You know, this has been through the actual part already.

37
00:02:52,560 --> 00:02:54,930
This part will be.

38
00:02:56,780 --> 00:03:02,450
So automatically I can just say user that you do not be and.

39
00:03:05,460 --> 00:03:06,090
Below this.

40
00:03:06,300 --> 00:03:09,240
What we need to do is we need to define our function.

41
00:03:11,260 --> 00:03:14,630
And public static extend message.

42
00:03:14,950 --> 00:03:21,400
W So we are using the extent to indicate that this is an outside function and this function does not

43
00:03:21,400 --> 00:03:24,280
have any knowledge about this.

44
00:03:24,280 --> 00:03:25,840
Our program class.

45
00:03:27,560 --> 00:03:29,840
So it has a return that is integer.

46
00:03:32,970 --> 00:03:42,690
So much as w so I'm making this, uh, like, uh, multiple lines because there'll be some functions

47
00:03:42,690 --> 00:03:46,710
that require more than five or six parameters in that you cannot write in single line.

48
00:03:50,290 --> 00:03:53,350
So the first, uh, parameter is.

49
00:03:54,330 --> 00:03:57,820
And so and also here you can see it brilliantly.

50
00:03:57,910 --> 00:04:05,090
That is the graphical user interface and dropping the ugly Windows applications.

51
00:04:05,830 --> 00:04:13,860
There'll be some main window and if you want to pop up a message box, you can pass that handle to this

52
00:04:14,400 --> 00:04:19,380
message box you're going to hand handle to the owner of window or the message box to be created.

53
00:04:19,800 --> 00:04:25,470
If this parameter is not, the message box has no owner so will be passing null for this because we

54
00:04:25,470 --> 00:04:31,740
are simply popping up the message box and we do not have any apparent graphical user interface windows.

55
00:04:33,340 --> 00:04:38,920
So first one should be null and no null means void.

56
00:04:39,580 --> 00:04:40,800
So it's not void.

57
00:04:40,840 --> 00:04:49,780
So actually white, you can pass any object type or you can pass any object type with an integer data.

58
00:04:49,780 --> 00:04:51,520
So that will be pretty resonant.

59
00:04:52,180 --> 00:04:56,560
But what we're going to do is we are going to say the pointer.

60
00:04:57,930 --> 00:04:58,830
In the winter.

61
00:05:01,110 --> 00:05:01,820
This kind of.

62
00:05:04,620 --> 00:05:11,610
So we have something this, uh, member of the structure in 2.0, which is Daniel.

63
00:05:11,700 --> 00:05:13,920
So we'll be using that in the 1.0.

64
00:05:15,200 --> 00:05:19,740
So next one is long pointer to constant white casting.

65
00:05:19,760 --> 00:05:23,180
So LP stands for the wrong pointer, c stands for constant.

66
00:05:23,180 --> 00:05:29,930
So it does not really uh, not constant means that our value does not change and.

67
00:05:31,470 --> 00:05:33,120
This is a wild card string.

68
00:05:33,120 --> 00:05:35,080
So we can be used.

69
00:05:35,100 --> 00:05:36,390
We can sit around.

70
00:05:38,690 --> 00:05:44,360
Martial as well, using these martial arts and not managed pay.

71
00:05:48,800 --> 00:05:49,240
DOT.

72
00:05:49,250 --> 00:05:57,110
So if you press unmanaged, you type dart and here you can see the rest of these manager types that

73
00:05:57,110 --> 00:05:59,300
can that can convert to.

74
00:05:59,840 --> 00:06:02,430
So here you can see a repeat of last year.

75
00:06:03,780 --> 00:06:05,970
We can also see some other stereotypes as well.

76
00:06:08,970 --> 00:06:15,120
So you can also see on unsigned integers and structures.

77
00:06:16,330 --> 00:06:17,080
And it is.

78
00:06:18,680 --> 00:06:20,120
And bold as well.

79
00:06:22,770 --> 00:06:23,820
So I'm going to be using.

80
00:06:31,340 --> 00:06:35,600
Wrong pointer to avoid getting to know what we can do.

81
00:06:35,600 --> 00:06:35,810
Either.

82
00:06:35,810 --> 00:06:39,320
You can simply screen and copy this text.

83
00:06:41,560 --> 00:06:48,670
So we are just putting these marshals and managers, they've got drunk pointer white casting before

84
00:06:48,670 --> 00:06:49,240
this string.

85
00:06:50,680 --> 00:06:53,470
So the next parameter is also the same.

86
00:06:53,470 --> 00:06:58,770
So this text will be shown on the message box and this caption is the title.

87
00:07:00,820 --> 00:07:02,680
So you can simply copy this one.

88
00:07:04,510 --> 00:07:07,780
And we can embrace a spring and we capture.

89
00:07:10,470 --> 00:07:13,200
And the last one is the tape of the message work.

90
00:07:13,200 --> 00:07:15,120
So we will be having some options.

91
00:07:15,120 --> 00:07:16,570
That is on time.

92
00:07:17,100 --> 00:07:23,210
And also here you can see if you pass this number based upon the number, the message box differs.

93
00:07:23,430 --> 00:07:26,640
So you have the okay button.

94
00:07:28,920 --> 00:07:31,590
Or get cancer, Bataan and so on, etc..

95
00:07:32,190 --> 00:07:35,720
So the type is an insane India.

96
00:07:38,910 --> 00:07:40,290
We can say you were in the party to.

97
00:07:42,650 --> 00:07:43,250
You take?

98
00:07:47,090 --> 00:07:47,460
Okay.

99
00:07:47,480 --> 00:07:48,770
My function is ready.

100
00:07:48,800 --> 00:07:53,630
I can now just simply say my search box w off.

101
00:07:54,590 --> 00:07:57,180
So the first one is a pointer.

102
00:07:57,410 --> 00:07:59,420
Da da gyro.

103
00:08:01,010 --> 00:08:04,310
That is the now and the second one is the second.

104
00:08:04,310 --> 00:08:05,990
Next two parameters are the settings.

105
00:08:06,320 --> 00:08:08,210
I want to say hello world.

106
00:08:09,670 --> 00:08:12,660
And the next one is this year's winner.

107
00:08:13,600 --> 00:08:13,780
Are you?

108
00:08:15,010 --> 00:08:18,490
And the last one, this type of damage is what you want to display.

109
00:08:18,850 --> 00:08:22,920
I want to just simply say, okay, that is Jairo Long.

110
00:08:23,170 --> 00:08:24,930
So you can just simply said you.

111
00:08:28,180 --> 00:08:30,220
And the return type is integer.

112
00:08:31,660 --> 00:08:34,770
And here you can also see the return type information.

113
00:08:36,090 --> 00:08:38,370
You can read the message about his cancer battle.

114
00:08:38,370 --> 00:08:40,110
The function of the Tyneside cancer.

115
00:08:41,500 --> 00:08:44,920
If it is sex if the function first that it normally do you know.

116
00:08:47,530 --> 00:08:50,800
The functions are normal in the following menu item values.

117
00:08:54,510 --> 00:08:54,800
Okay.

118
00:08:54,810 --> 00:08:57,030
That's the end result.

119
00:08:59,390 --> 00:09:03,500
Now before executive we can say counsellor that read key.

120
00:09:06,890 --> 00:09:08,420
So rich people can read this one.

121
00:09:08,780 --> 00:09:12,650
And here you can see we got this message box under the screen.

122
00:09:14,510 --> 00:09:18,380
And now this is the program is waiting for the user input.

123
00:09:18,770 --> 00:09:23,360
And then if I type if I put any gear, it stops.

124
00:09:24,260 --> 00:09:29,210
So you going to press any key to continue?

125
00:09:32,030 --> 00:09:37,220
So let me, uh, build this one and change the message box type.

126
00:09:40,480 --> 00:09:43,540
It's a yes no for this.

127
00:09:43,650 --> 00:09:45,130
And here you can see there is no.

128
00:09:45,340 --> 00:09:48,760
There is this yes and no options are available.

129
00:09:52,010 --> 00:09:54,440
So this is about how you use these windows.

130
00:09:54,540 --> 00:10:01,130
We're also going to be using we're bringing out other function that is getting that user's function.

131
00:10:03,200 --> 00:10:06,290
So get net, so get username.

132
00:10:06,320 --> 00:10:15,170
So we'll be using we'll be seeing the share net, the username in the next videos and also sharing them.

133
00:10:15,590 --> 00:10:16,670
So get username.

134
00:10:16,670 --> 00:10:20,880
W So if I type, who am I?

135
00:10:21,260 --> 00:10:23,390
We will get this target as the username.

136
00:10:23,390 --> 00:10:26,210
So we'll be getting the output from this function.

137
00:10:27,070 --> 00:10:31,270
And this function is in that one area that you do not deal.

138
00:10:32,200 --> 00:10:34,570
So you can create a new project.

139
00:10:34,690 --> 00:10:36,850
Let's just include here.

140
00:10:40,480 --> 00:10:44,080
And another thing is you can also define the characters set here.

141
00:10:44,530 --> 00:10:47,290
So I can say character is equal to.

142
00:10:48,980 --> 00:10:51,020
Characters are not unique.

143
00:10:51,220 --> 00:10:54,740
So now you can see the values unique and see another.

144
00:10:55,040 --> 00:10:59,750
So if I say Unicode by default, this function will be treated as a unique.

145
00:11:00,230 --> 00:11:02,120
Now let's go ahead and do this for you.

146
00:11:02,420 --> 00:11:03,770
And also common in this one.

147
00:11:04,970 --> 00:11:09,410
And now let's go into this w over this and run this one.

148
00:11:10,280 --> 00:11:15,080
So it will, by default, will be treated as Unicode function.

149
00:11:26,290 --> 00:11:26,480
Okay.

150
00:11:26,560 --> 00:11:27,160
Coming back.

151
00:11:27,310 --> 00:11:31,930
Let's import this real and public static at ten.

152
00:11:34,940 --> 00:11:36,860
And the return tape is bullion.

153
00:11:36,980 --> 00:11:40,910
So bullion is, uh, yes or no?

154
00:11:41,090 --> 00:11:42,170
Red Bull.

155
00:11:45,150 --> 00:11:45,540
Get.

156
00:11:47,140 --> 00:11:47,980
Username.

157
00:11:51,680 --> 00:11:52,980
He was a BMW.

158
00:11:57,720 --> 00:12:01,590
So the first parameter is, uh, our parameter.

159
00:12:01,590 --> 00:12:04,050
So you're going to see the out and in.

160
00:12:04,050 --> 00:12:06,600
So output is the output parameter.

161
00:12:06,870 --> 00:12:11,880
The soda function processes something both its function and things.

162
00:12:12,270 --> 00:12:19,500
And after, uh, before exiting the function, it will write the output to this, uh.

163
00:12:20,880 --> 00:12:21,960
But amateur spaceflight.

164
00:12:22,260 --> 00:12:25,920
And here you can also see in the magic box there is this window.

165
00:12:26,070 --> 00:12:30,440
So it means we need to go to these parameters like.

166
00:12:31,730 --> 00:12:34,260
Compulsory duty crosses he option optional.

167
00:12:34,280 --> 00:12:36,800
So that means you can just leave them.

168
00:12:37,220 --> 00:12:38,630
You can only pass this one.

169
00:12:39,020 --> 00:12:46,640
So that means the last parameter would use message box type is not an optional and it's compulsory for

170
00:12:46,640 --> 00:12:48,510
this message box to display.

171
00:12:49,870 --> 00:12:53,740
And now here you can see the output parameter.

172
00:12:56,200 --> 00:12:57,220
And in and out.

173
00:12:57,220 --> 00:13:06,310
So this means so we need to pass this as a reference because it's taking the input from this one and

174
00:13:06,310 --> 00:13:07,780
also it should write to the output.

175
00:13:09,240 --> 00:13:15,770
So the first one is before normal will be using the spring for this after then.

176
00:13:17,130 --> 00:13:26,550
And the user name of this machine gets into this before the pointer to receive the buffer, you know.

177
00:13:29,800 --> 00:13:30,580
So that's.

178
00:13:33,930 --> 00:13:34,670
Sacha Baron.

179
00:13:38,010 --> 00:13:39,150
Martial arts.

180
00:13:40,550 --> 00:13:41,740
And managed to that.

181
00:13:48,200 --> 00:13:49,520
So we consider spring.

182
00:13:52,490 --> 00:13:54,410
As we, not as we.

183
00:14:01,720 --> 00:14:04,870
And the next one is the number of bites.

184
00:14:08,520 --> 00:14:11,550
These are Eric Cantor.

185
00:14:12,450 --> 00:14:17,450
And also in our report, it shows the length of the username.

186
00:14:18,300 --> 00:14:20,160
So we need to pass this as reference.

187
00:14:28,310 --> 00:14:29,360
You're in 32.

188
00:14:33,090 --> 00:14:37,110
And so we are going to use this function.

189
00:14:39,490 --> 00:14:40,960
So let me comment on this.

190
00:14:43,080 --> 00:14:47,940
Right now, what we're going to do is copy this.

191
00:14:49,780 --> 00:14:54,760
So bird result is equal to your username w off.

192
00:14:56,540 --> 00:15:04,190
So the question is whether we need to create a string builder of yes, bicycles to new spring rolls.

193
00:15:05,120 --> 00:15:12,260
So we need to create 100 of this 100 of memories.

194
00:15:12,260 --> 00:15:15,410
Best to stop so we can just sit.

195
00:15:16,920 --> 00:15:17,520
SB.

196
00:15:18,180 --> 00:15:18,720
Come on.

197
00:15:22,730 --> 00:15:29,810
And we need to create an integer to specify this number of bytes it can show.

198
00:15:29,930 --> 00:15:35,990
So we can say you in 32 sizes equals zero.

199
00:15:36,290 --> 00:15:37,970
So for now it should be zero.

200
00:15:38,600 --> 00:15:41,030
And we be passing reference size.

201
00:15:43,040 --> 00:15:50,830
So we're good to go now after getting the result, we need to speed up to speed.

202
00:15:56,060 --> 00:15:58,940
Now let's go and build the solution.

203
00:15:59,450 --> 00:16:00,770
I hope everything is fine.

204
00:16:01,100 --> 00:16:01,970
So let's run this.

205
00:16:03,030 --> 00:16:04,440
So we did not get any output.

206
00:16:08,390 --> 00:16:10,760
So let's see where we did this wrong.

207
00:16:11,120 --> 00:16:15,070
A pointer to the buffer to receive the user's roundup.

208
00:16:23,980 --> 00:16:28,150
I think we are converting converting this as wrong.

209
00:16:42,320 --> 00:16:43,400
Let's bring.

210
00:17:45,380 --> 00:17:45,820
Okay.

211
00:17:46,040 --> 00:17:46,670
My word.

212
00:17:46,910 --> 00:17:49,040
What we're going to do is, uh.

213
00:17:49,430 --> 00:17:49,940
Sorry.

214
00:17:50,480 --> 00:17:50,900
I need to.

215
00:17:51,150 --> 00:17:54,050
I do not sprayed years as a candidate.

216
00:17:54,410 --> 00:17:56,300
That's why it is giving there.

217
00:17:56,820 --> 00:17:57,530
Sorry, Father.

218
00:17:59,720 --> 00:17:59,860
Now.

219
00:17:59,930 --> 00:18:01,280
Let's go and run this one.

220
00:18:02,950 --> 00:18:12,130
And now you can see the output so side for this I thought I thought it was only our parameter.

221
00:18:12,130 --> 00:18:12,700
I did not.

222
00:18:12,720 --> 00:18:13,120
Uh.

223
00:18:13,390 --> 00:18:14,500
I forgot this in.

224
00:18:20,280 --> 00:18:24,300
So here you can see you don't need to worry about the.

225
00:18:26,710 --> 00:18:30,640
This spring here because we are passing this time builder.

226
00:18:31,360 --> 00:18:32,740
Builder is a mutable type.

227
00:18:33,370 --> 00:18:35,260
Why the spring is immutable.

228
00:18:35,710 --> 00:18:47,440
So it is better to use spring buffer spring builder for these parameters and for the parameters we can

229
00:18:47,440 --> 00:18:49,450
normally use on normal springs.

230
00:18:51,760 --> 00:18:53,920
So that's what it's really all about.

231
00:18:53,920 --> 00:18:57,550
Covering the basics of how to use Windows app using the sheesha.
