Autoit Add data instead of replace data - autoit

Question

I start a server with:
$BungeeServer = Run("java -Xmx512M -jar " & '"' & $file0 & "\BungeeCord.jar" & '"', $file0, $Hide, $STDERR_MERGED)
Then I get the data from the server with(It's in a while loop):
Assign("sOutput", StdoutRead($BungeeServer, False, False) & #CRLF)
GUICtrlSetData($Edit1, $sOutput)
The problem is that It only returns the latest string of information. I need it to add instead of replace the values. Anybody know an easy way to do that?
Edit: When a server starts, you normally get a cmd window. I want to be able to have it in a Gui instead. Also I only want it to appear when I click a button, still it should start getting data when the server starts. The lines of text also went outside the box. I tried:
Do
$msg1 = GUIGetMsg()
$line1 = StdoutRead($BungeeServer, True)
$totalOutput1 &= $line1 & #CRLF
GUICtrlSetData($Edit1, $totalOutput1)
$line2 = StdoutRead($1, True)
$totalOutput2 &= $line2 & #CRLF
GUICtrlSetData($Edit2, $totalOutput2)
$line3 = StdoutRead($2, True)
$totalOutput3 &= $line3 & #CRLF
Until $msg = $GUI_EVENT_CLOSE
The edit boxes were made with:
$Form2 = GUICreate("Servers", #DesktopWidth - 15, #DesktopHeight - _GetTaskBarHeight() - 35, -1, -1)
$Edit1 = GUICtrlCreateEdit("", 0, 0, 634, 334, BitOR($ES_AUTOVSCROLL, $ES_AUTOHSCROLL, $ES_READONLY, $ES_WANTRETURN, $WS_VSCROLL))
Font()
$Edit2 = GUICtrlCreateEdit("", 635, 0, 634, 334, BitOR($ES_AUTOVSCROLL, $ES_AUTOHSCROLL, $ES_READONLY, $ES_WANTRETURN, $WS_VSCROLL))
Font()
$Edit3 = GUICtrlCreateEdit("", 634 + 634, 0, 634, 334, BitOR($ES_AUTOVSCROLL, $ES_AUTOHSCROLL, $ES_READONLY, $ES_WANTRETURN, $WS_VSCROLL))
Font()
GUISetState(#SW_SHOW)
Edit: I found a better way to do it where I made a child window and didn't need all the other stuff:
$GUI = GUICreate("Consoles", 1020, 600, 1282, 300, BitOR($WS_MINIMIZEBOX, $WS_SYSMENU, $WS_CAPTION, $WS_CLIPCHILDREN, $WS_POPUP, $WS_POPUPWINDOW, $WS_GROUP, $WS_BORDER, $WS_CLIPSIBLINGS))
If GUICtrlRead($Bungee) = 1 Then
$BungeeServer = Run("java -Xmx512M -jar " & '"' & $file0 & "\BungeeCord.jar" & '"', $file0, $Hide)
If Not ProcessWait($BungeeServer) = 0 Then
WinSetTitle("C:\Windows\system32\java.exe", "", "Bungee")
WinSetTitle("C:\WINDOWS\SYSTEM32\java.exe", "", "Bungee")
Global $hwnd0 = WinGetHandle("Bungee")
EndIf
EndIf
_WinAPI_SetWindowLong($hwnd0, $GWL_EXSTYLE, $WS_EX_MDICHILD)
_WinAPI_SetParent($hwnd0, $GUI)
WinMove($hwnd0, "", 0, 0, 340, 300)
Still need to find a way to use ControlSend to the child windows :/

Answer 1

Use StdoutRead($BungeeServer, True)
StdoutRead ( process_id [, peek = false [, binary = false]] )
peek [optional] If true the function does not remove the read characters from the stream.
OR
Consider storing the previous data before getting the new one. Instead of assigning the new data to the variable, you can just add it.
eg.
$totalOutput &= $newOutput & #LF
About StdoutRead: In order to get all data, it must be called in a loop.
From the help file:
; Demonstrates StdoutRead()
#include <Constants.au3>
Local $foo = Run(#ComSpec & " /c dir foo.bar", #SystemDir, #SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
Local $line
While 1
$line = StdoutRead($foo)
If #error Then ExitLoop
MsgBox(0, "STDOUT read:", $line)
WEnd
While 1
$line = StderrRead($foo)
If #error Then ExitLoop
MsgBox(0, "STDERR read:", $line)
WEnd
MsgBox(0, "Debug", "Exiting...")
Considering all above, StdoutRead should be used like this:
Local $sOutput
While 1
$line = StdoutRead($foo, True)
If #error Then ExitLoop
$sOutput = $line
WEnd
OR
Local $sOutput
While 1
$line = StdoutRead($foo)
If #error Then ExitLoop
$sOutput &= $line & #LF
WEnd
