I never get an error when this function fails (error handling)

[CaptainBeardsEyesBeard]

So I'm trying to find out why it's not inputting into this rate box however I never get the error msg I've put in for error handling

Func InputRate($Rate)   
Local $hWnd1 = WinWait("[CLASS:ThunderRT6FormDC]", "", 10)ControlSend($hWnd1, "", "ThunderRT6TextBox13", $Rate)
If @error = 1 Then   MsgBox(($MB_ICONINFORMATION, "", "Cannot enter $Rate number")
EndIf  
FileWrite($hFilehandle, @CRLF & $Rate)
Sleep(4000)

EndFunc

How come I don't get the msgbox?

Where does it state in the helpfile that the @eeror is set?

Return Value

Success:	a handle to the requested window.
Failure:	0 if timeout occurred.

Just test for the returned value in $hWnd1.

OK, so to do that I would do the below? I tried it and it doesn't work either.

Func InputRate($Rate)  
Local $hWnd1 = WinWait("[CLASS:ThunderRT6FormDC]", "", 10)
ControlSend($hWnd1, "", "ThunderRT6TextBox13", $Rate)If $hWnd1 = 1 Then   
MsgBox(($MB_ICONINFORMATION, "", "Cannot enter $Rate number")
EndIf  

FileWrite($hFilehandle, @CRLF & $Rate)
Sleep(4000)
EndFunc

That's not the way you check if you have a valid handle.
Take a look at IsHWnd() function.
And, watch out of your indentation...

If you want to test for an error then test for the value that is returned in case of an error. This value is 0 (according to Jos' post.
So try:

Func InputRate($Rate)  
    Local $hWnd1 = WinWait("[CLASS:ThunderRT6FormDC]", "", 10)
    If $hWnd1 = 0 Then   
        MsgBox(($MB_ICONINFORMATION, "", "Cannot enter $Rate number")
    Else
        ControlSend($hWnd1, "", "ThunderRT6TextBox13", $Rate)
        FileWrite($hFilehandle, @CRLF & $Rate)
    EndIf  
EndFunc

Bizarre I tried that and still don't get any msg box coming up to say it's failed

Post your code so that we can the the revisions you have made. Also, isn't it possible that there's another window with this same class? Try using WinList to get a list of matching windows and then display the resulting array.
