WMI Data Retrieval FAQ posted 2

[Glenn9999]

I posted a FAQ on how to get data (hardware info, threads, processes, and so forth) from WMI for a computer. The specific example is how to get a list of command-lines for running processes.

To show the power of what WMI can do, here's all the tasks (minus the temporary directory) listed in the FAQ section, which should represent a good cross-sample of call examples.

Get total physical memory in machine:
SELECT TotalPhysicalMemory FROM Win32_ComputerSystem

Get Free space and disk size for logical drive letter:
SELECT DeviceID, FreeSpace, Size FROM Win32_LogicalDisk

Get Computer Name:
SELECT Name FROM Win32_ComputerSystem

Get processor clock speed:
SELECT CurrentClockSpeed FROM Win32_Processor

Get Windows System Directory:
SELECT SystemDirectory FROM Win32_OperatingSystem

Get Windows Version (e.g. 5.1.2600 for Windows XP):
SELECT Version FROM Win32_OperatingSystem

Get current logged on user:
SELECT UserName FROM Win32_ComputerSystem

The temporary directory function can be done in WMI but involves a method call, and I run into the same issue as the thread I posted on it.

Microsofts WMI Code Creator is a great way to look at what is avaliable to you via WMI queries.

I was working with some more WMI code and I had the thought of possibly turning this into a component if I can make things easier in the long run with it (and I don't know the answer to that). Is there any interest in this if I were to share it?

Anyway the main question I had regarding this is as follows: What would one look like? Would it be worth trying to tie it into the data-aware controls, or would it be too off-spec for what WMI code would be used for?

Maybe I'm getting at this: How do you know when a component would be handy as opposed to code like was posted in the FAQ?
