Buttons and loops

[Klovis]

So I want to click this button once and after I click it the first time it will receive new properties, the first time It connects to the IP you put in input1 then the second time you press it, it will send what is in input1. But I failed and I'm lost.

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $IP, $TCPConnect, $i = 0

TCPStartup()

$Form1 = GUICreate("Client", 108, 23, 373, 441, -1, $WS_EX_TOPMOST)
$Input1 = GUICtrlCreateInput("0.0.0.0", 0, 0, 66, 21)
$Button1 = GUICtrlCreateButton("Connect", 72, 0, 35, 21)
GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            If $i = 0 Then
                $IP = GUICtrlRead($Input1)
                $TCPConnect = TCPConnect($IP, 5000)
                GUICtrlSetData($Button1, "Send")
            EndIf
            $i = 1
            If $i = 1 Then
                TCPSend($TCPConnect, GUICtrlRead($Input1))
                GUICtrlSetData($Input1, "")
            EndIf
    EndSwitch
WEnd

Try this

Case $Button1
    If $i = 0 Then
        $IP = GUICtrlRead($Input1)
        $TCPConnect = TCPConnect($IP, 5000)
        GUICtrlSetData($Button1, "Send")
        $i = 1
    Else
        TCPSend($TCPConnect, GUICtrlRead($Input1))
        GUICtrlSetData($Input1, "")
    EndIf

Try this

Case $Button1
    If $i = 0 Then
        $IP = GUICtrlRead($Input1)
        $TCPConnect = TCPConnect($IP, 5000)
        GUICtrlSetData($Button1, "Send")
        $i = 1
    Else
        TCPSend($TCPConnect, GUICtrlRead($Input1))
        GUICtrlSetData($Input1, "")
    EndIf

It's always the else I forget. Thanks Cartmen ^^
