#include <StaticConstants.au3>
#include <WindowsConstants.au3>


GUICreate("Form 1", 682, 293, 561, 164)
$input1 = GUICtrlCreateInput("", 16, 48, 649, 21)
$input2 = GUICtrlCreateInput("", 16, 138, 649, 21)
GUICtrlSetLimit(-1, 90)
$input3 = GUICtrlCreateInput("", 16, 222, 649, 21)
GUICtrlSetLimit(-1, 90)
GUICtrlCreateLabel("Input 1", 16, 16, 100, 20)
GUICtrlSetFont(-1, 10, 800, 0, "Verdana")
GUICtrlCreateLabel("Input 2", 16, 102, 78, 20)

HotKeySet("{F3}", "_msgSend")

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd

Func _msgSend()
    If GUICtrlRead($input1) >= 0 Then
        Send("{ENTER}")
        Sleep(1000)
        Send(GUICtrlRead($input1))
        Send("{ENTER}")
        Sleep(500)

send tab instead of send enter?

I have problem with this only, i need to check if field is not empty what operator to use > or = '' or  = 0

If GUICtrlRead($input1) >= 0 Then

its not like in other languages like in php for example, so if 1st field is empty skip it, else if 2nd field empty skip it else do stuff.

Im confused with this comparsion operators in autoit <> >= =< 

If ($input) == '' {
    echo 'dont do enything';
} else if ($input2) == '' {
    echo 'dont do nothing';
} else {
    echo 'do stuff';
}

This is so confused :/

So zero is threated like empty field as i saw, why then when i compare if field is greater than nothing i get this message "Field 1 empty !"

so if field is empty or i put something in it give me message that is empty 

there is no operator like       if ( !empty )    or    if ( empty ) ?

If GUICtrlRead($input1) > 0 Then
        Send("{ENTER}")
        Sleep(1000)
        Send(GUICtrlRead($input1))
        Send("{ENTER}")
        Sleep(500)
    Else
        MsgBox(48, "Error", "Field 1 empty !")
    EndIf

i use ="" to represent empty

If you need to make sure that spaces are treated as empty as well I suggest:

#include <StringConstants.au3>
If StringStripWS(GUICtrlRead($input1), $STR_STRIPALL) = "" Then

[akira2891]

its a bit hard because im learning autoit, i know php but this is diferent especialy this comparsion operators like this for example

// php
if (!empty($var1)) { // if not empty
    // do stuff
}


// autoit
If GUICtrlRead($input1) = "" Then ; how to check here if not empty
                Send("{ENTER}")
        Sleep(1000)
        Send(GUICtrlRead($input1))
        Send("{ENTER}")
        Sleep(500)
    EndIf

[alienclone]

If GUICtrlRead($input1) <> "" Then ; this should work

If not GUICtrlRead($input1) = "" Then ; this may also work

[akira2891]

Now works normal 

Func _msgSend()
    If Not GUICtrlRead($input1) = "" Then
        Send("{ENTER}")
        Sleep(1000)
        Send(GUICtrlRead($input1))
        Send("{ENTER}")
        Sleep(500)
    EndIf

    If Not GUICtrlRead($input2) = "" Then
        Send("{ENTER}")
        Sleep(1000)
        Send(GUICtrlRead($input2))
        Send("{ENTER}")
        Sleep(500)
    EndIf

    If Not GUICtrlRead($input3) = "" Then
        Send("{ENTER}")
        Sleep(1000)
        Send(GUICtrlRead($input3))
        Send("{ENTER}")
        Sleep(500)
    EndIf
EndFunc
