VB - WMIBrowser

Windows Managemet Instrumentation (WMI) provides access to a huge set of information about a Computer System running Windows. Unfortunately it's not too easy to identify exactly where a piece of information is and what is actually available. The WMI Browser goes some way towards helping.

It starts off by enumerating all the WMI Namespaces (logical divisions of the WMI Classes). Clicking on a Namespace will display all the Classes within that Namespace. In the resulting TreeView, the operator has the options of (obviously, expanding the Nodes) and:

(a) Clicking on a Class name - The Results TreeView will display all the Properties and Methods (if any) associated with the Class. Clicking on a Property will display its Type.

(b) Checking the CheckBox displayed next to a ClassName - Will execute that class immediately and display the results in the Results TreeView.

The program uses the WMI semi-synchronous access method to execute the Class, so it is possible (in most casses) to halt the execution of the Class if required. (Some Classes may execute for a long time. eg Displaying all the Installed Software products)

I wrote this in July 2006 and have used it successfully fairly frequently but it may contain the odd bug or two that I haven't come upon yet. I have tested it under Vista (recently, as an Administrative User), XP SP2 (Home Edition), Windows 2000, and ME and it appears to function correctly under all of them.

Note that not all the WMI Classes are necessarily implemented, those prefixed 'CIM' with no 'WIN32' sub-classes normally return "No Results to Display" and even some of the 'WIN32' classes return the same result.

Happy browsing :D
