Hi!
In some words, everything! You can use any programming language if you got the interpreter/libs.
You can retrieve a lot of things, like your computer's hardware, software, using WMI, make Windows Registry operations, do SQL requests to databases, etc..., open Office and modify files...
It's limited to the software support for the .NET Framework.
I think the list of objects is huge, but here are some:
- WScript.Shell : similar to MS-DOS, similar to mIRC's /run, but retrieves results.
- WbemScripting.SWbemLocator : access to the WMI (system's harware, software...).
- LDAP: : Microsoft Active Directory.
- Scripting.FileSystemObject : list directories, files
- MAPI.Session : send E-mail
- Outlook.Application : edit E-mail and send
- InternetExplorer.Application
- Word.Application
- Excel.Application
etc...
This will boost the mIRC cool features but there's a hic

It seems that's broken

Look at

Maybe the next version will work with COM.
