Code Removed

Okay, I am trying to make a minecraft server GUI. I am attempting to figure out how to run commands through the window, and cannot seem to get STDIN to work correctly. Anyone see the problem?

Basically, the button gets clicked - server starts, clicked again - send stop command

Can't really help you because I don't know what STDIN is but isn't there an official GUI version of a Minecraft server?

This might be the problem:

I stripped out the rest of the code to highlight the problem.

If $sRunning = 0 Then
    $sRunning = 1
ElseIf $sRunning = 1 Then
    $sRunning = 1 ; should this be set to 0?
EndIf

Yes, and I like my design better, just gotta get it workin!

And no, that just says whether to start or stop it. That can go 0 after the button works.

Easier way would be to do it this way:

$sRunning = Not $sRunning

If you wanted to keep the value of $sRunning a numeral instead of a true/false you could also do the same thing this way.

$sRunning = Number(Not $sRunning)

Edit: Thought of a different method for using a number in place of true/false, after I posted :unsure:

I will change that for version one, thanks Brew - I forgot about that method. Also, does anyone know what the issue is with StdInWrite?

Full code was now posted in OP. Anyone have any ideas?

Looking at your code, it looks like you're killing the java process before sending the stop command to it, there's nothing left for the StdInWrite to write to at that point. When you press restart, are you doing it before you've restarted the process? If not, there's nothing for StdInWrite to write to at that point either because it's not running.

This is from just quickly scanning your code and I could be mistaken.

Look closer, ProcessClose is commented out

If you change these lines, what is the console output when you run the script?

Global $sServer = Run(@ComSpec & " /k java -Xincgc -Xms768M -Xmx768M -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=4 -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui", "C:\Users\" & @UserName & "\AppData\Roaming\.minecraft server\bin\", @SW_HIDE, BitOR($STDIN_CHILD, $STDERR_CHILD, $STDOUT_CHILD))
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $sServer = ' & $sServer & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
;The above console out put should be the PID of the process when you start Java with no error code showing

;~ And these lines

$Result = StdinWrite($sServer, "stop" & @CRLF)
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $Result = ' & $Result & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
; This should tell you how many characters are sent to the process, also with no error codes

Just some basic error checking to see where you might be having the issue.

I actually downloaded the bukkit server software to test this because it intrigued me. I could NOT get the StdInWrite to work with it no matter how I tried to start it. So, I figured out that the changes below should work for you.

ElseIf $sRunning = 1 Then
    ControlSend("C:\Windows\system32\cmd.exe", "", "", "stop {ENTER}")
;~      ProcessClose("java.exe")
;~  StdinWrite($sServer, "stop" & @CRLF)
    $sRunning = 0
    _GUICtrlStatusBar_SetText($StatusBar1, "Server Status: Not Running", 0)
    GUICtrlSetData($Button3, "Start")

I've never used StdInWrite before, but it appears to not work with a Java console window, but ControlSend works great.

Ah ha! Thanks so much for your help, fixed the problem :unsure:

Heh, I recently made a GUI for minecraft servers with autohotkey_l. From what I understand, the languages are pretty similar. I've decided to rewrite it in java to get cross-platform support (ended up here searching for how to send input to the console!). You're more than welcome to examine my code if you'd like for any ideas. source (unfortunately not well commented)

Good luck!
