Hi,
While reading this post by @Peter Simpson , I realized that I was still using a very old (!) Autoit function to retrieve my computer informations: CompInfo by JSThePatriot
Until now, I was executing this AutoIt function and returning to result as Json to parse in B4J. So I have converted it to B4J using Gemini as a base and developed further on it.
The class contains about 30 methods that give very detailed information about your computer (or a remote computer). To use it locally just use "" as the computer name, or to execute it remotely you can give the computer name or ip address.
Libraries used:
Json, jShell
Note about remote execution:
For the remote execution to work across a network, the following conditions must be met:
1. Network/Domain: Both computers generally need To be on the same network, And ideally on the same Active Directory Domain.
2. Permissions: The Windows account running your B4J app must have Administrator or WMI-access privileges on the target remote computer.
3. WinRM Enabled: The target computer must have Windows Remote Management (WinRM) And PowerShell remoting enabled
(usually done by running Enable-PSRemoting -Force in an admin PowerShell prompt on the target PC).
4. Firewall: The target PC's firewall must allow incoming WMI and WinRM traffic.
Note about the Types:
Each function returns a list of specific Types (all starting with "CompInfo_") so that it's easy to retrieve the information. Each Type also contains a "AsMap" method in case you need to store the raw data in a DB for example. There is an example code snippet for each method.
Note about Video Controllers:
Since the function is based on WMI Win_32, it can't display more than 4 GB of ram for the GPU, so I added another function called "ComputerGetGPUInfo"
Note about bytes:
A lot of methods return the data as bytes, so I added a method to convert the bytes to human readable string:
Note:
Since it's using WMI and Powershell, it's Windows ONLY!
I included both the compiled library and the source code, as well as an example B4J project.

!! Enabling WinRM increase security risks !! Read about it before doing it.

B4X:
Log(ci.FormatBytes(GPU2.VRAMBytes))Note:

Example:
Dim ci As CompInfo
ci.Initialize("")
For Each App As CompInfo_InstalledSoftware In ci.ComputerGetInstalledSoftwares
Log("DisplayName: " & App.DisplayName)
Log("DisplayVersion: " & App.DisplayVersion)
Log("Publisher: " & App.Publisher)
Log("UninstallString: " & App.UninstallString)
Next
