How to get terminal server IDsession like qwinsta.exe or query session in VB.NET (.NET 5)

Hello,
I'm developing an RDP application that also support shadow connect, I have to read active ID sessions to connect with shadow, but How can I get it like using qwinsta.exe on powershell or query session on cmd?

Thanks

Hi @Stefano Fattori ,
In order to get terminal services session information, you can take a look at the following reference:
Grabbing Information of a Terminal Services Session Programmatically
You can consider converting the code to visual basic.

Thank you so much, really!

Unfortunately I discovered that I can't do a shadow session connect using mstsclib.dll and I didn't find any other solutions...
The only way is call external mstsc.exe /shadow but I can't include it in my GUI application...

Hi, but this code is to use on local terminal server... Instead I have to get ID session on a terminal server by another computer.. because than I have to create an RDP shadow connect...

Hi @Stefano Fattori ,

I can't do a shadow session connect using mstsclib.dll

Maybe there are other ways to shadow session : Terminal Server : shadow a session using AxMSTCLib
For qwinsta.exe, hope this reference could be helpful.
