1 00:00:01,600 --> 00:00:02,520 Slowly from everyone. 2 00:00:02,520 --> 00:00:04,710 Welcome back to desktop application course. 3 00:00:04,710 --> 00:00:11,250 And in today's class we are going to study about rich text boxes and text of applications and we'll 4 00:00:11,250 --> 00:00:13,370 see tool tips as well. 5 00:00:13,380 --> 00:00:21,680 Basically when we already we have seen all we have experience in dealing with not packed like applications. 6 00:00:21,720 --> 00:00:23,090 We have seen notepad. 7 00:00:23,100 --> 00:00:29,280 We have worked on notepad and we have seen similar applications like Notepad. 8 00:00:29,310 --> 00:00:31,970 OK so what that text box is. 9 00:00:32,130 --> 00:00:33,800 Which textbooks basically. 10 00:00:33,810 --> 00:00:41,460 So if you wish to add that similar functionality inside your application desktop application so you 11 00:00:41,460 --> 00:00:44,500 can use rich textbooks instead of normal textbooks. 12 00:00:44,640 --> 00:00:52,050 And what are the tooltip are to live is basically a message or a pop up that appears when you will focus 13 00:00:52,050 --> 00:00:53,250 is a particular control. 14 00:00:53,300 --> 00:00:53,790 OK. 15 00:00:53,910 --> 00:00:57,770 So we'll see both of these in this lecture number nine. 16 00:00:57,780 --> 00:00:58,420 Let's start. 17 00:00:59,050 --> 00:00:59,320 OK. 18 00:00:59,340 --> 00:01:04,510 So I have created a new window with the name rich text box example. 19 00:01:04,710 --> 00:01:09,410 And in this particular window I am taking a little textbooks here. 20 00:01:09,450 --> 00:01:11,480 I have my rich textbooks look. 21 00:01:11,820 --> 00:01:16,280 This is a huge text box and you can work in like a notepad. 22 00:01:16,300 --> 00:01:16,930 OK. 23 00:01:16,980 --> 00:01:27,490 So if I docket in a parent container look and when I run this application from here from programmers. 24 00:01:27,510 --> 00:01:27,930 Yes. 25 00:01:28,020 --> 00:01:32,340 Right now for this example which text box example. 26 00:01:34,980 --> 00:01:36,520 OK save it. 27 00:01:36,540 --> 00:01:41,430 Let me zoom in so my first start up a screen will be my rich textbooks 28 00:01:46,610 --> 00:01:47,450 look. 29 00:01:47,580 --> 00:01:52,530 So it is very similar to my notepad application. 30 00:01:52,700 --> 00:01:53,090 OK. 31 00:01:53,090 --> 00:01:56,330 It is very similar to my notepad application. 32 00:01:56,330 --> 00:02:01,630 And you can then save this file to your hard drive. 33 00:02:01,880 --> 00:02:02,800 You can save this file. 34 00:02:03,390 --> 00:02:03,680 OK. 35 00:02:03,680 --> 00:02:06,770 You can open this file again inside this rich textbooks. 36 00:02:06,770 --> 00:02:10,280 So all these are the things that we can do in file handling as well. 37 00:02:10,370 --> 00:02:10,980 OK. 38 00:02:11,060 --> 00:02:16,460 So I'll introduce you in this lecture how to handle how to create a file. 39 00:02:16,610 --> 00:02:17,010 OK. 40 00:02:17,030 --> 00:02:18,240 How to save this file. 41 00:02:18,500 --> 00:02:20,330 So let's see and work in IT 42 00:02:23,590 --> 00:02:24,000 OK. 43 00:02:24,150 --> 00:02:32,880 So first thing I wanted to do is let me open this window and let me talk it out or make it OK. 44 00:02:32,910 --> 00:02:33,600 None. 45 00:02:33,660 --> 00:02:37,980 We'll get this as marriage textbooks and right. 46 00:02:38,070 --> 00:02:49,320 Let me take a label and give it a name and your text. 47 00:02:49,320 --> 00:02:50,320 OK. 48 00:02:50,430 --> 00:02:57,960 And then I'm creating some buttons one is for save then 49 00:03:00,510 --> 00:03:01,170 another button. 50 00:03:01,170 --> 00:03:04,440 But first of all I am taking this button as save. 51 00:03:05,250 --> 00:03:06,270 OK. 52 00:03:06,270 --> 00:03:10,650 Save and then open. 53 00:03:12,120 --> 00:03:12,430 OK. 54 00:03:13,260 --> 00:03:17,710 So these are my two buttons. 55 00:03:17,970 --> 00:03:19,380 This is massive buttons. 56 00:03:19,670 --> 00:03:23,100 Give it a name as save button. 57 00:03:23,100 --> 00:03:24,860 And this is my open button. 58 00:03:24,870 --> 00:03:29,820 So give it name as open button Ok open and button. 59 00:03:31,440 --> 00:03:32,170 OK. 60 00:03:32,460 --> 00:03:38,550 So what ever you wrote inside this rich textbooks should be saved to a file for. 61 00:03:38,600 --> 00:03:40,830 For using file handling. 62 00:03:40,830 --> 00:03:45,790 You have to come here inside your code and you have to import using System Dot. 63 00:03:45,820 --> 00:03:49,610 Are your input output without this file you cannot be. 64 00:03:49,620 --> 00:03:53,130 You are unable to open file handling controls and classes. 65 00:03:53,130 --> 00:03:53,700 OK. 66 00:03:53,760 --> 00:04:01,380 So first of all I'm checking a condition if my textbooks my name off my textbooks is this is my rich 67 00:04:01,500 --> 00:04:01,980 textbooks. 68 00:04:01,980 --> 00:04:06,400 Let me close other windows so that I can get my textbooks to design. 69 00:04:06,420 --> 00:04:13,350 This is my list textbooks so name it as bad our text let me use paragraph text. 70 00:04:13,350 --> 00:04:13,590 OK. 71 00:04:13,620 --> 00:04:20,880 So if I write here about our text that text is not equal to empty. 72 00:04:20,880 --> 00:04:23,320 That means you should have some text. 73 00:04:23,370 --> 00:04:23,680 OK. 74 00:04:24,120 --> 00:04:27,260 So if you're a paragraph text is not equal to empty. 75 00:04:27,270 --> 00:04:28,940 Then do what file. 76 00:04:28,980 --> 00:04:32,520 This is a class for using file handling file. 77 00:04:32,610 --> 00:04:37,480 Dot write all text write or text. 78 00:04:37,530 --> 00:04:38,700 What does this method do. 79 00:04:38,700 --> 00:04:40,230 This method creates a new file. 80 00:04:40,880 --> 00:04:41,900 OK. 81 00:04:41,910 --> 00:04:50,790 This method creates a new file and write a specified string to the file you think is specified encoding 82 00:04:50,790 --> 00:04:57,390 and then it closes the file in the target file already exists then it will be overridden if the target 83 00:04:57,390 --> 00:04:59,880 file already exists then it will be overridden. 84 00:04:59,910 --> 00:05:07,950 So you have to mention the file name and you have to if the file already exists then you can this file 85 00:05:07,950 --> 00:05:09,430 will be that file will be audited. 86 00:05:09,450 --> 00:05:09,870 OK. 87 00:05:09,960 --> 00:05:12,810 So write or text right or lines look. 88 00:05:12,860 --> 00:05:13,840 Right. 89 00:05:13,950 --> 00:05:19,260 A new file create a new file by using a specified encoding with a with the collected data collection 90 00:05:19,260 --> 00:05:21,900 of the strings to the file and then closes the file. 91 00:05:21,930 --> 00:05:22,640 Right all right. 92 00:05:22,650 --> 00:05:25,130 If you have bytes if you have a bite at it. 93 00:05:25,400 --> 00:05:25,820 OK. 94 00:05:26,010 --> 00:05:32,930 So said creation times at loss X this time read all text read lines replace. 95 00:05:32,940 --> 00:05:40,740 You have many options in the file class so that you can use you look open read Open Text open move you 96 00:05:40,740 --> 00:05:45,900 can do whatever you wish to do with your file you can delete your file you can encrypt and decrypt your 97 00:05:45,900 --> 00:05:53,700 file and you can create or you can do anything copy append text if you wish to add existing text to 98 00:05:53,700 --> 00:05:54,750 your New You. 99 00:05:54,770 --> 00:05:56,970 It's very new text to your existing file. 100 00:05:57,090 --> 00:06:03,880 You can use all these functions so right now I am creating what I am creating right. 101 00:06:03,930 --> 00:06:11,130 All text I'm doing this one right all text it is asking me the part of my file where should I save my 102 00:06:11,130 --> 00:06:11,580 file. 103 00:06:11,970 --> 00:06:17,240 So I giving a part to my documents window so for documents window. 104 00:06:17,250 --> 00:06:26,750 Let me take apart from this string s all you can write apart equal to environment. 105 00:06:26,760 --> 00:06:31,580 We have another class environment that get special folder. 106 00:06:31,580 --> 00:06:36,750 Get folder part and open this bracket and it is asking me to give my special folder. 107 00:06:37,020 --> 00:06:41,340 So environment our special folder docked my documents. 108 00:06:42,340 --> 00:06:43,540 OK. 109 00:06:44,160 --> 00:06:51,480 So this is the way to go through your mind documents but every P.C. had a by default my documents folder 110 00:06:52,020 --> 00:06:58,110 so you can access that my documents folder by using the environment class and then using the get folder 111 00:06:58,110 --> 00:07:04,020 path method and it is accepting environment our special folder so that you can access my documents all 112 00:07:04,020 --> 00:07:07,850 your Downloads folder or your pictures folder or videos for the next day. 113 00:07:08,590 --> 00:07:09,220 Is that clear. 114 00:07:09,880 --> 00:07:10,190 OK. 115 00:07:10,380 --> 00:07:12,680 So this is all you can get your My Documents. 116 00:07:12,690 --> 00:07:15,320 But then you reach to your My Documents. 117 00:07:15,330 --> 00:07:22,390 But inside that part you are trying to save your file so you you will give the a name you will give 118 00:07:22,390 --> 00:07:23,200 a name to your file. 119 00:07:23,220 --> 00:07:23,560 Okay. 120 00:07:23,770 --> 00:07:30,910 So how can you take the name you can take the name from here from your text box. 121 00:07:30,990 --> 00:07:35,330 Okay Lexi I'm taking a text box here. 122 00:07:35,970 --> 00:07:43,890 Text box and here you are specifying that Please enter your file link. 123 00:07:44,020 --> 00:07:46,720 Okay let me make it a little bit down. 124 00:07:47,650 --> 00:08:02,940 Okay now copy this label and paste it here and save now file limb by limb by limb and this is file Lim 125 00:08:02,950 --> 00:08:03,430 text 126 00:08:06,270 --> 00:08:08,620 file name text. 127 00:08:08,840 --> 00:08:10,830 Okay now what. 128 00:08:10,830 --> 00:08:12,120 Come in your save button. 129 00:08:12,120 --> 00:08:23,790 If this bed is not empty and and file name text dark text is not equal to empty. 130 00:08:23,790 --> 00:08:25,290 I hope it is cleared now. 131 00:08:25,290 --> 00:08:32,560 So if both the file name and this the better text are not blank then this code will be executed. 132 00:08:32,610 --> 00:08:41,060 So when I wanted to save my file here in the path that I have taken of my documents inside this path 133 00:08:41,100 --> 00:08:44,180 document I am entering file. 134 00:08:44,190 --> 00:08:52,490 That is my file name text or text so why I have use this thing. 135 00:08:53,040 --> 00:09:01,660 I used this thing because I have used this thing because let me show you the path look. 136 00:09:02,460 --> 00:09:04,820 So you leave your documents. 137 00:09:04,880 --> 00:09:05,780 Okay. 138 00:09:05,940 --> 00:09:12,360 When you click here look and when you apply a backslash you'll get all the files so you are creating 139 00:09:12,360 --> 00:09:15,280 your file you are saving your file inside your documents. 140 00:09:15,300 --> 00:09:19,230 So this is your documents by then when I applied backslash buttons encoding. 141 00:09:19,350 --> 00:09:26,360 You have to apply a double backslash so that it can be understood by a C sharp combined. 142 00:09:26,370 --> 00:09:32,430 That is the single backslash whenever if you wish to apply a backslash you can not enter a single backslash 143 00:09:32,430 --> 00:09:39,690 you have to enter double backslash for part okay or you have to add editor symbol before you but otherwise 144 00:09:39,690 --> 00:09:40,800 it will not entertain you. 145 00:09:41,280 --> 00:09:43,280 Okay now the next thing is the content. 146 00:09:43,380 --> 00:09:46,610 Where is my content my content is in that text. 147 00:09:46,610 --> 00:09:47,280 Don't text. 148 00:09:47,310 --> 00:09:49,540 So I have given my content. 149 00:09:49,770 --> 00:09:54,860 After doing this write a message what it is returning it is returning nothing. 150 00:09:54,870 --> 00:09:56,330 So write a message. 151 00:09:56,580 --> 00:09:58,260 White sorry. 152 00:09:58,260 --> 00:10:00,830 Message box. 153 00:10:00,840 --> 00:10:05,160 Message box door to file created 154 00:10:08,050 --> 00:10:10,130 successfully. 155 00:10:10,230 --> 00:10:10,660 Okay. 156 00:10:11,710 --> 00:10:14,430 So Alexis started this program and checked what will happen. 157 00:10:19,600 --> 00:10:22,300 This is my application. 158 00:10:22,300 --> 00:10:24,820 Let me zoom it. 159 00:10:24,910 --> 00:10:27,380 I'm entering some text. 160 00:10:27,820 --> 00:10:30,100 Hi. 161 00:10:30,100 --> 00:10:36,170 Hope you are enjoying. 162 00:10:36,250 --> 00:10:36,610 OK. 163 00:10:37,840 --> 00:10:38,290 OK. 164 00:10:38,290 --> 00:10:39,400 Hope you are enjoying. 165 00:10:39,410 --> 00:10:43,720 I have skipped the space after this message. 166 00:10:43,780 --> 00:10:49,530 I have to give my file name and my filing will be welcome. 167 00:10:49,610 --> 00:10:51,100 Got the expertise. 168 00:10:51,520 --> 00:10:56,140 And when I press the save button is saying we file created successfully. 169 00:10:56,380 --> 00:10:58,770 And after creating this file let us stick. 170 00:10:58,810 --> 00:10:59,690 Is that is it. 171 00:10:59,700 --> 00:11:02,320 Is that file created or not. 172 00:11:02,320 --> 00:11:06,430 Yes I have created this file on my harddrive double click on it. 173 00:11:06,430 --> 00:11:07,890 Look. 174 00:11:08,160 --> 00:11:11,810 So this is how you can create a notepad like application in C sharp. 175 00:11:12,680 --> 00:11:15,180 OK moving forward. 176 00:11:15,580 --> 00:11:17,920 Let's check some more options. 177 00:11:17,920 --> 00:11:19,790 What if I wanted to. 178 00:11:19,870 --> 00:11:26,630 What will happen if I add a new texture new content. 179 00:11:26,980 --> 00:11:32,140 OK if I'm writing new content here and then saving the blessing to save. 180 00:11:32,140 --> 00:11:35,940 But then again then the file created successfully again. 181 00:11:35,950 --> 00:11:41,740 The method has been shown on the screen but this time this time what will happen. 182 00:11:41,890 --> 00:11:48,550 My this welcome file will be replaced with my new file the previous file has been replaced with my new 183 00:11:48,550 --> 00:11:55,360 file the text with the text will not be appended because I don't text method creates new file every 184 00:11:55,360 --> 00:12:00,400 time and replace the existing file so you can avoid this thing by using some different methods. 185 00:12:00,400 --> 00:12:00,990 How. 186 00:12:01,030 --> 00:12:09,600 Let us see now I am adding one more condition inside my C sharp code that if file not exists. 187 00:12:09,610 --> 00:12:14,700 This is my class and this is a method that exists file not exist. 188 00:12:14,890 --> 00:12:19,060 If my file exists this is a boolean method that means it will return true or false. 189 00:12:19,450 --> 00:12:23,130 Okay so file not exist will I should enter my path. 190 00:12:23,530 --> 00:12:31,500 So this bot should come before this if else so that I can get my bot and can idea bot concatenation 191 00:12:31,840 --> 00:12:37,060 and you have to enter the file name when you you have already. 192 00:12:37,300 --> 00:12:39,790 When you press the button the file name should also be there. 193 00:12:39,820 --> 00:12:45,890 OK so same file lame file name text not text. 194 00:12:46,150 --> 00:12:51,310 If this file exists OK in this but then what to do. 195 00:12:51,490 --> 00:12:59,950 You can show a message which message lacks a message box starts to file 196 00:13:02,620 --> 00:13:05,110 already exists. 197 00:13:05,620 --> 00:13:06,210 OK. 198 00:13:06,220 --> 00:13:07,810 File already exist. 199 00:13:07,930 --> 00:13:08,560 Else 200 00:13:11,130 --> 00:13:15,470 as do this in the file already exist. 201 00:13:15,480 --> 00:13:17,750 It will not carry it will not right. 202 00:13:17,760 --> 00:13:22,310 OK now a file already exists then what to do file. 203 00:13:23,010 --> 00:13:31,950 But you can ask the user at runtime that do you want to add or replace or do you do you want to open 204 00:13:31,980 --> 00:13:34,570 the new content into your existing file. 205 00:13:34,710 --> 00:13:35,970 Then what will you do. 206 00:13:36,000 --> 00:13:40,100 So let me take a new class that is. 207 00:13:40,380 --> 00:13:48,310 This is a property basically and it belongs to some class of dialog reserved dialog result. 208 00:13:48,410 --> 00:13:55,490 The what this class will do this class will get the response off your message box. 209 00:13:55,740 --> 00:13:58,960 You might have seen when your message box appears on the screen. 210 00:13:59,070 --> 00:14:02,970 The key button is coming by default in the message box. 211 00:14:03,030 --> 00:14:03,420 Okay. 212 00:14:03,720 --> 00:14:08,930 But I wanted to display yes and no inside my message box. 213 00:14:08,970 -->

00:15:24,690 --> 00:15:32,480 OK now you can check if the R is equal to equal to dialog result. 233 00:15:32,490 --> 00:15:37,200 That's the property that yes if yes has been the. 234 00:15:37,520 --> 00:15:39,800 That is all that is stored in the art. 235 00:15:39,880 --> 00:15:52,030 Then what you can do you can do file for the file but append all lines append or text and append text. 236 00:15:53,000 --> 00:16:00,000 OK so I am taking this append all text and it is asking me the same thing append means to add to join 237 00:16:00,530 --> 00:16:07,920 to do to concatenate your existing or your new text with your existing text OK or your new string with 238 00:16:07,920 --> 00:16:13,230 your existing string so append or text what it is asking me without asking me the part. 239 00:16:13,500 --> 00:16:23,210 So part is my this one and the file name is file name text dot text. 240 00:16:23,370 --> 00:16:29,680 This is my complete path off my file and the contents will be better. 241 00:16:29,790 --> 00:16:31,870 Text don't text. 242 00:16:32,180 --> 00:16:39,340 OK so what would have been let's have a look again if my book text books are not empty. 243 00:16:39,480

new file. 283 00:18:47,000 --> 00:18:51,170 Let's check go through your documents. 284 00:18:51,170 --> 00:18:52,590 Double click on it. 285 00:18:52,660 --> 00:18:57,680 Days because in the previous example I have created again the new file. 286 00:18:57,680 --> 00:19:05,570 So let me add once more save and step out step out. 287 00:19:05,570 --> 00:19:08,870 Yes I wanted to append and see what

here also we have to say double backslash. 291 00:19:23,900 --> 00:19:24,800 OK. 292 00:19:24,820 --> 00:19:30,570 After that after my documents but look double back let's keep it updating after each directory see. 293 00:19:30,610 --> 00:19:34,140 Then double backslash users and double backslash and then only then documents. 294 00:19:34,180 --> 00:19:37,570 So after documents I have skipped this double backslash for my file. 295 00:19:37,570 --> 00:19:43,360 So I have applied this double backslash here and now I'll check what will happen append IFRS def 11 296 00:19:43,360 --> 00:19:45,310 key so to move forward. 297 00:19:45,370 --> 00:19:46,660 Now what will happen next. 298 00:19:50,400 --> 00:19:59,570 Close this file and come here Open this file look the new data has been up and it will file. 299 00:19:59,580 --> 00:20:06,010 You can apply a line break speech breaks and you can do everything whatever you can do in your notepad. 300 00:20:06,030 --> 00:20:08,670 So this is all you can use the rich textbooks. 301 00:20:08,730 --> 00:20:11,160 This is the example of your rich textbooks. 302 00:20:11,160 --> 00:20:15,720 So I am not going to cover all the expense of a notepad right now. 303 00:20:15,760 --> 00:20:21,850 OK so now let's go to our next topic that is are toolbar tooltip. 304 00:20:21,890 --> 00:20:25,470 How can I apply tooltip inside this this text box. 305 00:20:25,470 --> 00:20:27,520 Let us select tooltip. 306 00:20:27,520 --> 00:20:28,560 Where is my tooltip. 307 00:20:28,560 --> 00:20:34,940 Here is my tooltip drag and drop it here tooltip has no physical appearance on your screen. 308 00:20:34,980 --> 00:20:35,530 OK. 309 00:20:35,550 --> 00:20:39,810 In fact it shows in the bottom of your visual studio. 310 00:20:40,140 --> 00:20:47,940 So when you select you or you apply a tooltip inside your application its properties are these OK so 311 00:20:47,940 --> 00:20:54,960 tooltip will appear or it will stay for almost half seconds and popup delay order probably is almost 312 00:20:54,960 --> 00:21:00,810 five seconds and then these are the properties the four color the back color the initial delay is balloon 313 00:21:00,810 --> 00:21:02,820 tooltip visual delay. 314 00:21:03,000 --> 00:21:08,490 So these are the timings that you can configure with your tooltip by default I am not changing anything 315 00:21:08,770 --> 00:21:09,490 on this show. 316 00:21:09,490 --> 00:21:16,180 The tooltip will appear anytime if you will if you select this particular property to do then you're 317 00:21:16,200 --> 00:21:18,050 to issuing any every name. 318 00:21:18,270 --> 00:21:18,870 Okay. 319 00:21:19,110 --> 00:21:25,910 And then tooltip I can tooltip title to use animation use fading. 320 00:21:25,920 --> 00:21:28,360 So all these are properties of your tooltip. 321 00:21:28,380 --> 00:21:29,190 Let me show you. 322 00:21:29,190 --> 00:21:32,040 I can hear in full. 323 00:21:32,060 --> 00:21:32,900 Let's see. 324 00:21:32,970 --> 00:21:37,540 Message data is in full and the icon is let's say in full. 325 00:21:37,560 --> 00:21:39,300 And that's it. 326 00:21:39,300 --> 00:21:41,890 Right now we leave it to these two properties. 327 00:21:41,890 --> 00:21:51,260 And now when you come here on your filing that Paul give should appear so select your file name text 328 00:21:51,260 --> 00:22:02,690 box come bottom and look for tooltip look you'll see this particular tooltip on every control. 329 00:22:03,330 --> 00:22:11,460 Once you have applied a tooltip inside your application so select your tooltip tooltip on tooltip one 330 00:22:12,750 --> 00:22:16,260 determine the tooltip shown whether when the mouse who was under control. 331 00:22:16,290 --> 00:22:22,010 OK so presenter to begin a new line give you a message. 332 00:22:22,020 --> 00:22:25,780 What what do you wanted to display please. 333 00:22:25,980 --> 00:22:26,320 And 334 00:22:28,950 --> 00:22:34,800 file name with extension. 335 00:22:35,210 --> 00:22:41,520 OK so that no one can get a mistake without file extension. 336 00:22:41,580 --> 00:22:42,000 OK. 337 00:22:42,120 --> 00:22:44,940 So let's check this whether the tooltip appears or not. 338 00:22:46,020 --> 00:22:50,190 So when our focus is here look this is my tooltip. 339 00:22:50,190 --> 00:22:51,970 If I if I zoom in. 340 00:22:51,990 --> 00:22:56,190 This is my tooltip and I've come out are going to come in again. 341 00:22:56,190 --> 00:22:57,170 Look. 342 00:22:57,510 --> 00:23:03,750 So you can increase the appearance of your tooltip with respect to seconds and degrees as well. 343 00:23:03,750 --> 00:23:08,370 Let me show select your tooltip again. 344 00:23:08,370 --> 00:23:10,140 Look all they show. 345 00:23:10,200 --> 00:23:12,490 Where was that all this show. 346 00:23:12,570 --> 00:23:14,210 This one double click. 347 00:23:14,370 --> 00:23:17,400 Stuck on racial 348 00:23:22,200 --> 00:23:33,510 so it will any time you come here on your textbooks look it is showing again and again in a more faster 349 00:23:33,510 --> 00:23:43,680 manner you can increase delay you can make it's delayed to zero let's say there is no delay next week 350 00:23:44,740 --> 00:23:48,210 then you come up it is coming 351 00:23:51,130 --> 00:24:00,700 look and if you remove this delay to two thousand or two possibly to two thousand two thousand means 352 00:24:00,700 --> 00:24:06,010 two seconds you have to enter time in milliseconds and your windows C sharp. 353 00:24:06,610 --> 00:24:07,420 So let's stick 354 00:24:10,360 --> 00:24:13,120
