B4J Question Shutting down PC with Jshell

[Reminisce]

Hello everyone, I've searched the forum, but nothing comes close to what I want to achieve. I built a simple app on b4a, that uses socket and asynstreams to send commands to my b4j client. But jshell is not executing those commands.

Sub astreams_NewData (Buffer() As Byte)
	Dim receivecommand As String = BytesToString(Buffer,0,Buffer.Length,"UTF-8")
	
	Select receivecommand
		
		Case "SHUTDOWN"
			Dim l As List
			Log(receivecommand)
			l.Initialize
			l.Add("SYSTEMINFO")
			shell.Initialize("shell","cmd.exe",l)
			shell.WorkingDirectory = "C:\WINDOWS\system32\"
			shell.Run(-1)
			Wait For  shell_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
			Log(StdOut)
			Log(Success)
					
	End Select
	
End Sub

[\code ]

The above code receives the command, but doesn't execute it. I

Tip:

Dim l As List
            Log(receivecommand)
             l.Add("SYSTEMINFO")

Can be written like this:

Dim l As List = Array("SYSTEMINFO")

You probably need to add /c as the first argument.

I don't understand @Erel, where should I add /c? I expected cmd to come up with the system info command already executed. I'll need this to shutdown my pc too using the "shutdown /p" command.

1. Type "shutdown /s" to Shutdown your computer;
2. Type "shutdown /r "to Restart your windows PC;

if you want restart PC after 10 Min use: "shutdown –s –t 600"

Thanks for your reply. I know these commands. My problem is jshell isn't executing them whenever I pass it.

Thank you, I'll try the power shell example in the other thread. On another hand, what if I save these commands in a ".bat" file. How do I execute bat files.?

File batch Windows (.bat)

I can run a Windows batch file (.bat)? it's possible ?

Backup (dump) Sqlite tables via jShell + *.bat file

If you use SQlite in your apps in you need to do backups. A bad decision is just to copy the database file: - there will be more than one file when the database is online (e.g. *.wal and other files) - this will create a broken db-file when you copy it when the db is busy doing i/o operations...
