WEBVTT 00:06.460 --> 00:14.300 You have learned that objects contain members and that those members consist of properties methods anti-wealth 00:14.600 --> 00:19.420 to this point to this course you have used properties of objects. 00:19.420 --> 00:27.460 Now you will be able to use methods methods tell an object to perform some action or task repository 00:27.460 --> 00:37.000 or objects that you Querrey with WMI or see him frequently have methods that reconfigure their manageable 00:37.180 --> 00:40.900 components that the objects represent. 00:40.930 --> 00:48.810 For example that re-inserted to discuss service class-C instances represent background services. 00:48.850 --> 00:58.690 The class a change method that reconfigures many of the settings for a service that include its logon 00:58.690 --> 01:02.260 password name and start mode. 01:02.260 --> 01:09.940 If you know the class that represents the manageable component that you want to reconfigure you can 01:09.940 --> 01:17.410 discover the methods of that class by use and get mamber for example get WMI object. 01:17.440 --> 01:23.930 This class Winsford to discuss service pipe get member or GM. 01:23.950 --> 01:28.090 The resulting list will display all available methods. 01:28.090 --> 01:31.990 Remember that not every class or for small sets. 01:32.020 --> 01:35.680 So sometimes the list may not include any methods. 01:35.800 --> 01:44.260 The output of get member does not explain how to use the methods unless you are already know how to 01:44.260 --> 01:45.010 use them. 01:45.040 --> 01:47.980 You have to find the documentation for the class. 01:48.070 --> 01:50.550 The same technique will not work with. 01:50.550 --> 01:58.780 Get some instance because the objects are returned by that command do not have a complete set of methods. 01:58.780 --> 02:01.710 Instead you would run this command. 02:01.810 --> 02:10.920 Get some class first class to do just cause service by select object Desch expand property. 02:10.990 --> 02:12.840 Same class methods. 02:12.850 --> 02:18.910 There is no efficient way to search across all classes for a given method. 02:19.000 --> 02:26.980 To do this in Windows POAs shell you would have to wear it every class by each one to get mamber and 02:26.980 --> 02:31.880 search that output for a method name or keyword. 02:31.900 --> 02:39.330 This approach would be very time consuming and impractical and Internet search engine would pro-white 02:39.460 --> 02:44.160 faster and easier way to search for classes and methods. 02:44.170 --> 02:52.720 So let's talk a bit about in documentation method documentation if any exists will be included on the 02:52.720 --> 02:56.650 documentation or web page on the repository class. 02:56.650 --> 03:02.190 Remember that repository classes are not typically well documented. 03:02.350 --> 03:10.090 Especially classes not in their root seem the two namespace and Internet search engine is the fastest 03:10.090 --> 03:16.070 way to find the documentation for a class after the class name into a search engine. 03:16.090 --> 03:23.830 And one of the first few search results will typically be the class documentation page. 03:23.860 --> 03:28.110 The documentation page will include a section named Masset. 03:28.200 --> 03:30.880 There are other classmates that are listed. 03:30.880 --> 03:36.090 You can click any method name to display instructions for using that method. 03:36.250 --> 03:42.760 They mainly use all the documentation is to determine that arguments each message requires. 03:42.760 --> 03:50.760 For example the re-inserted to shut down method or that when so to underscore operating system class 03:51.000 --> 03:53.560 except as a single argument. 03:53.620 --> 03:58.150 The argument is an integer and it lets the Masset. 03:58.270 --> 04:02.990 What kind of shut down restart or other action to take. 04:03.100 --> 04:10.240 Well let's take a look at some demonstration examples you'll see how to discover class methods and how 04:10.240 --> 04:12.350 to find their documentation. 04:12.430 --> 04:22.090 So to display the members of re-inserted to underscore service class just type get WMI object the class 04:22.090 --> 04:27.430 name re-inserted to underscore service and pipe it to get mamber. 04:27.490 --> 04:30.760 Here you can find change method for example. 04:30.850 --> 04:39.040 So to use Windows powers cell to display the definition for change method of VIN so to to service type 04:39.280 --> 04:49.350 got WMI object class re-inserted to service by GET member pipe their name equals change and pyper to 04:49.350 --> 04:52.690 form a list by name and definition. 04:52.690 --> 05:00.070 Now let's find online documentation for the change set of incertitude service you have to open a web 05:00.070 --> 05:09.690 browser go to some search engine like Google or bin and events or to to discuss service as a search 05:09.750 --> 05:17.110 term in the search result click Vincit to underscore a service class for Windows. 05:17.250 --> 05:24.900 And you could find and I'm as dn documentation page and read about this method. 05:24.990 --> 05:30.740 So scroll down to the mansard section list and then click change. 05:30.780 --> 05:38.010 You can find that the method has 11 parameters and you can review all these parameters.
