Autoit and notepad - automation

Question

I have an application, wherein I get a "Save As" dialog-box. At times, if a file exists with the same name, then another dialog box comes in, with the same name "Save As". The following is the code, which I wrote but it doesn't work as expected.
Global $sTitle = "Save As"
WinWait($sTitle)
WinWaitActive($sTitle)
ControlClick($sTitle, "Save", "[CLASS:Button; TEXT:&Save; INSTANCE:2]")
ControlSetText($sTitle, "", "CLASS:Button; INSTANCE:2]", $file_name)
SendKeepActive($sTitle)
Send("{ENTER}")
Sleep(4000)
WinWaitActive($sTitle,"",3)
If WinExists($sTitle, "No") Then Send("{ENTER}")
If WinExists("Exit OmniPeek") Then
Send("{ENTER}")
Else
Sleep(2000)
WinClose($closing_file)
EndIf
The idea is to check if the second "Save As" dialog box comes and if does come in, then over-write the existing file. This however, doesn't seem to be working with the autoit script that I wrote.
Can someone help me with this script? You can re-create the issue by using Notepad as well. Just have a file with a name abc.txt and try to save a file with the same name
You will get another dialog box with the name "Save As".

Try this:
Example()
Func Example()
; Run Notepad
Run("notepad.exe")
; Wait 10 seconds for the Notepad window to appear.
Local $hWnd = WinWait("[CLASS:Notepad]", "", 10)
; Keep the Notepad window active when using the Send function.
SendKeepActive("[CLASS:Notepad]")
; Simulate entering a string of text. If you try to change to a different window other than Notepad, then the Notepad window will
; be brought to focus again.
For $i = 1 To 10
Sleep(5)
Send("notepad - ")
Next
; Disable the Notepad window being active when using the Send function.
SendKeepActive("")
; Close the Notepad window using the handle returned by WinWait.
WinClose($hWnd)
Send("{ENTER}") ; <<< SAVE
; Now a screen will pop up and ask to save the changes, the classname of the window is called
; "#32770" and simulating the "TAB" key to move to the second button in which the "ENTER" is simulated to not "save the file"
WinWaitActive("[CLASS:#32770]", '', 2)
Sleep(50)
Send('newName.txt')
Sleep(1000)
Send("{TAB}{ENTER}")
EndFunc ;==>Example
