1 00:00:05,000 --> 00:00:05,000 Hello, friends. 2 00:00:05,000 --> 00:00:15,000 Today I will tell you how to protect your VI or how to make your VI password protected. 3 00:00:17,000 --> 00:00:26,000 In that case, only front panel is visible to your customer or your candidate. 4 00:00:27,000 --> 00:00:31,000 He will not able to open the block diagram window. 5 00:00:31,000 --> 00:00:34,000 As you see over here, I have a VI. 6 00:00:34,000 --> 00:00:35,000 I just run it. 7 00:00:35,000 --> 00:00:39,000 This is a simple VI to. 8 00:00:40,000 --> 00:00:44,000 Fill the tank and empty the given tank. 9 00:00:45,000 --> 00:00:48,000 Okay, so right now, just stop it. 10 00:00:50,000 --> 00:00:51,000 So. 11 00:00:53,000 --> 00:00:58,000 As you see, when I just stop, click on Stop button. 12 00:01:00,000 --> 00:01:01,000 Or here 13 00:01:06,000 --> 00:01:07,000 after the. 14 00:01:09,000 --> 00:01:12,000 Given time, it will stop, as you see right now. 15 00:01:13,000 --> 00:01:19,000 So to protect your VI, you just go to the files. 16 00:01:20,000 --> 00:01:23,000 Over here, we have VI properties. 17 00:01:24,000 --> 00:01:26,000 In the properties. 18 00:01:26,000 --> 00:01:32,000 As you see, we have category general category is there you just go to. 19 00:01:33,000 --> 00:01:35,000 The protection over here. 20 00:01:36,000 --> 00:01:37,000 Just select the production. 21 00:01:37,000 --> 00:01:40,000 As you see over here, we have three options. 22 00:01:40,000 --> 00:01:44,000 First one unlocked means no password. 23 00:01:44,000 --> 00:01:50,000 Is there any user can view and edit the front panel and block diagram of your. 24 00:01:52,000 --> 00:01:54,000 There is the second case logged. 25 00:01:55,000 --> 00:01:57,000 But no password, is there. 26 00:01:57,000 --> 00:02:05,000 A user must unlock this VI from this dialog to edit the front panel and block diagram. 27 00:02:06,000 --> 00:02:09,000 Okay, so let's do it. 28 00:02:09,000 --> 00:02:11,000 First, now the logged VI. 29 00:02:12,000 --> 00:02:13,000 So just make it logged. 30 00:02:14,000 --> 00:02:16,000 And I just save this guy. 31 00:02:18,000 --> 00:02:20,000 To my desktop also. 32 00:02:23,000 --> 00:02:24,000 Create a. 33 00:02:25,000 --> 00:02:28,000 And I want to just. 34 00:02:30,000 --> 00:02:30,000 Save this. 35 00:02:35,000 --> 00:02:36,000 Surveys. 36 00:02:39,000 --> 00:02:41,000 And also rename it. 37 00:02:45,000 --> 00:02:46,000 On the desktop. 38 00:02:53,000 --> 00:02:55,000 So this is my given VI. 39 00:03:02,000 --> 00:03:04,000 So I just make it over here. 40 00:03:04,000 --> 00:03:06,000 So I just save it now. 41 00:03:06,000 --> 00:03:13,000 I just close this, so I just go to my desktop when I just run it. 42 00:03:13,000 --> 00:03:19,000 As you see over here, only front panel is there when I just press control E. 43 00:03:20,000 --> 00:03:22,000 Then it is open. 44 00:03:24,000 --> 00:03:27,000 I just again go to the properties. 45 00:03:28,000 --> 00:03:29,000 As you see. 46 00:03:31,000 --> 00:03:35,000 When I just go to the password protected over here. 47 00:03:35,000 --> 00:03:38,000 Let's say I just put any password. 48 00:03:40,000 --> 00:03:44,000 It is four digit password right now. 49 00:03:44,000 --> 00:03:44,000 I just. 50 00:03:45,000 --> 00:03:46,000 Save it. 51 00:03:48,000 --> 00:03:49,000 Then I just close it. 52 00:03:50,000 --> 00:03:51,000 Save it. 53 00:03:51,000 --> 00:03:53,000 And when I need to. 54 00:03:53,000 --> 00:03:57,000 Close your eyes and the view. 55 00:03:59,000 --> 00:04:09,000 Okay, So as you see right now, I just close my lab view, and when I just again click on Tank, it 56 00:04:09,000 --> 00:04:24,000 will open only front panel or here, as you see when I just go for control E it is demanding password 57 00:04:25,000 --> 00:04:31,000 or you can just go show block diagram over here it is demanding the password. 58 00:04:31,000 --> 00:04:42,000 I just put my password verify it as you see root right now I just got the my block diagram. 59 00:04:42,000 --> 00:04:43,000 Okay. 60 00:04:43,000 --> 00:04:49,000 Now you can change the VI or you can change the block diagram window. 61 00:04:49,000 --> 00:04:54,000 So now I just change the file. 62 00:04:56,000 --> 00:04:58,000 Properties from here. 63 00:04:59,000 --> 00:05:03,000 I just go to the again protection right now. 64 00:05:03,000 --> 00:05:05,000 I just lock it. 65 00:05:05,000 --> 00:05:10,000 So to lock it, I just verify this. 66 00:05:10,000 --> 00:05:12,000 Password is verified. 67 00:05:13,000 --> 00:05:14,000 Remove protection. 68 00:05:14,000 --> 00:05:15,000 Yes. 69 00:05:15,000 --> 00:05:17,000 I just make it lock only. 70 00:05:17,000 --> 00:05:24,000 Now you have to just again close the save it again in this case. 71 00:05:24,000 --> 00:05:27,000 Also, you just need to close all the. 72 00:05:27,000 --> 00:05:31,000 LabVIEW VI running LabVIEW programs. 73 00:05:31,000 --> 00:05:34,000 So right now I just close this. 74 00:05:35,000 --> 00:05:37,000 As you see, it is closed. 75 00:05:37,000 --> 00:05:41,000 Now I again click on tank button. 76 00:05:46,000 --> 00:05:48,000 Thank VI over here. 77 00:05:52,000 --> 00:05:56,000 In this case it is not password protected, but it is locked. 78 00:05:57,000 --> 00:06:01,000 So I just go to VI, as you see over here. 79 00:06:02,000 --> 00:06:04,000 I just got my VI. 80 00:06:05,000 --> 00:06:05,000 Okay. 81 00:06:05,000 --> 00:06:09,000 So this is how you can protect your VI. 82 00:06:11,000 -->
