1 00:00:00,690 --> 00:00:09,260 Hello and welcome to this lecture in this lecture we are going to be looking at some basic arithmetic. 2 00:00:09,360 --> 00:00:14,250 Operators commonly used in business applications 3 00:00:16,680 --> 00:00:19,990 so these are the basic operators. 4 00:00:20,070 --> 00:00:24,480 So we've got the addition with the symbol of the plus sign. 5 00:00:24,480 --> 00:00:33,050 I'm sure we are all familiar with these operators subtraction multiplication and division. 6 00:00:33,090 --> 00:00:39,180 Notice that for the multiplication in parentheses I've called it asterisks. 7 00:00:39,240 --> 00:00:46,650 This is because in C sharp the asterisks is what is used to implement multiplication. 8 00:00:46,650 --> 00:00:57,450 If you are trying to program or code an arithmetic function for multiplication if you're trying to code 9 00:00:57,450 --> 00:01:09,080 for a division you'll be using this slash symbol to represent division let's create a project that we 10 00:01:09,080 --> 00:01:13,040 can use to implement these arithmetic operators. 11 00:01:13,040 --> 00:01:14,630 So I've got my vision study here. 12 00:01:14,630 --> 00:01:19,000 I'm going to right click and go run as administrator and then click. 13 00:01:19,010 --> 00:01:21,340 Yes. 14 00:01:22,100 --> 00:01:29,190 So Visual Studio as launched I'm going to click new project. 15 00:01:29,330 --> 00:01:31,580 Give it time to load 16 00:01:35,030 --> 00:01:38,490 trying to initialize the templates. 17 00:01:38,610 --> 00:01:40,510 All right so call it templates up. 18 00:01:40,650 --> 00:01:44,170 So I'm going to use web was called templates. 19 00:01:44,200 --> 00:01:45,680 Got web selected. 20 00:01:45,810 --> 00:01:53,520 I'm going to go for airspeed on net application and this is where I give the application a name when 21 00:01:53,520 --> 00:01:55,200 they mean your application. 22 00:01:55,200 --> 00:02:00,710 If you're using more than one word try not to create spaces between them. 23 00:02:00,950 --> 00:02:05,520 So I'm going to call mine same basic 24 00:02:09,560 --> 00:02:10,470 operators. 25 00:02:10,470 --> 00:02:19,840 Notice the couples tell ization of the second word and I click OK. 26 00:02:24,110 --> 00:02:30,700 OK so next in our selected empty template on the ad folders and core references make sure you go to 27 00:02:30,710 --> 00:02:32,450 web form selected. 28 00:02:32,450 --> 00:02:34,670 This will enable us to add. 29 00:02:34,760 --> 00:02:36,800 Let her on and click. 30 00:02:36,890 --> 00:02:39,250 OK. 31 00:02:40,010 --> 00:02:41,830 Let's add our form. 32 00:02:41,930 --> 00:02:44,880 So where's got the name of your. 33 00:02:44,960 --> 00:02:45,610 Here we go. 34 00:02:45,610 --> 00:02:54,770 Basic operators right click and click on the ship should be an option to add and click on a web form 35 00:02:55,700 --> 00:02:58,880 then give you a web form a name. 36 00:02:58,880 --> 00:03:01,460 I'm going to call my default and click OK 37 00:03:06,440 --> 00:03:09,070 so it opens up in this view. 38 00:03:09,140 --> 00:03:15,890 I'm going to switch to design which is this tab here and I'm going to add some controls. 39 00:03:16,040 --> 00:03:26,240 I'm going to add a text box a button and a label so I click on it to click on that and text box can 40 00:03:26,240 --> 00:03:35,300 scroll down where the textbook says make sure I put my mouse where I want to put a text box and go back 41 00:03:35,300 --> 00:03:37,830 to my control double click. 42 00:03:38,420 --> 00:03:46,850 And a tool inserted where I have placed the mouse so I just drag it along a little bit and just tab 43 00:03:46,850 --> 00:03:47,720 down. 44 00:03:48,020 --> 00:03:49,950 Next thing I want to do is add a button. 45 00:03:49,970 --> 00:03:58,080 So where I've got the mouse cursor flashing there I just go back to my control look for the button. 46 00:03:58,580 --> 00:04:01,110 This should be one full button. 47 00:04:01,460 --> 00:04:02,110 Larry go. 48 00:04:02,120 --> 00:04:05,390 Just double click and it will insert the button there. 49 00:04:05,390 --> 00:04:09,840 Finally I want a label so where the mouse is flashing. 50 00:04:09,890 --> 00:04:15,370 I go back to Tool Box go down double click on label. 51 00:04:15,700 --> 00:04:17,150 So I've got all my controls. 52 00:04:17,150 --> 00:04:25,020 I just need to change the I.D. on the labels or click on the first one which is it tells you that's 53 00:04:25,020 --> 00:04:28,650 a text box one I need to change that name. 54 00:04:28,880 --> 00:04:32,560 Scroll down to the I.D. part of it. 55 00:04:32,620 --> 00:04:36,820 No words got the I.D. I'll just change that to input text box 56 00:04:46,650 --> 00:04:47,010 gain. 57 00:04:47,020 --> 00:04:53,720 Notice a capitalization of the first letter of each word. 58 00:04:53,730 --> 00:04:56,860 I come here to the bottom. 59 00:04:56,860 --> 00:05:00,500 I'm going to change that too. 60 00:05:03,120 --> 00:05:04,130 Okay. 61 00:05:04,130 --> 00:05:09,700 Button will also change the text on the button. 62 00:05:09,760 --> 00:05:11,040 There should be a text. 63 00:05:11,230 --> 00:05:15,490 So rather than it's a button I'm gonna say something else. 64 00:05:15,490 --> 00:05:16,480 Going to click that 65 00:05:19,890 --> 00:05:20,850 and typing okay. 66 00:05:20,860 --> 00:05:23,680 And that you change from button to OK. 67 00:05:23,680 --> 00:05:29,260 Finally the label came to label here I'm going to make the text blank. 68 00:05:29,260 --> 00:05:30,840 I don't want any text there. 69 00:05:31,060 --> 00:05:33,130 So the text should disappear. 70 00:05:33,430 --> 00:05:45,260 I just need to change the I.D. on that label and if click on it so I can see it. 71 00:05:46,120 --> 00:05:46,570 All right. 72 00:05:46,570 --> 00:05:48,580 Found the label. 73 00:05:48,580 --> 00:05:52,930 Just need to rename that to result 74 00:05:56,410 --> 00:05:59,620 label again. 75 00:05:59,620 --> 00:06:06,280 Notice a capitalization on the first letter of the second word. 76 00:06:06,280 --> 00:06:12,100 So we've created the basic form for our application. 77 00:06:12,100 --> 00:06:16,470 We'll use this to test out the basic operators. 78 00:06:16,510 --> 00:06:23,560 So I'm gonna stop this lecture here and in the subsequent lectures that follows I will be testing out 79 00:06:23,680 --> 00:06:28,960 each of these operators using this application interface. 80 00:06:28,960 --> 00:06:30,340 We have built. 81 00:06:30,340 --> 00:06:32,170 So that's it for this lecture. 82 00:06:32,170 --> 00:06:33,610 Thanks for watching. 83 00:06:33,790 --> 00:06:34,720 Bye for now.
