Extra enter stroke added for unknown reason.


Recommended Posts

I wrote this little script:

#include <GUIConstants.au3>

$add_note = GUICreate("Add Note", 524, 276, 271, 162)
$textbox = GUICtrlCreateEdit("", 8, 8, 505, 201)
$Button_Add = GUICtrlCreateButton("Add Note", 424, 224, 91, 41, 0)
GUISetState(@SW_SHOW)
$message = String("")

While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
        Case $msg = $Button_Add
                $message = GUICtrlRead($textbox)
                Send("!{TAB}")
                Send($message)
    EndSelect
WEnd

Which just grabs the text in the editbox and puts into the application behind it. But when it transfer the text over an extra enter appears when transfered - as shown below.

Is this a bug or am i missing something, any help would be great :)

Weird, after checking it, it's definitely a "Send" issue, seems it's putting an extra crlf in there.

The reason I say that, is if you use "FileWrite" on he same thing, it comes out correct.

To fix the issue temporarily, Send(StringReplace($message, @LF, '')) works.

Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

?? strange

before this case

#include <GUIConstants.au3>

GUICreate("Add Note", 524, 276, 271, 162)
$textbox = GUICtrlCreateEdit("", 8, 8, 505, 201)
$send = GUICtrlCreateButton("send all to file", 4, 215, 150, 25)
GUISetState()

While 1
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    If $msg = $send Then SendMyData()
WEnd

Func SendMyData()
    FileDelete('test.inf')
    $data = GUICtrlRead($textbox)
    FileWrite('test.inf', $data)
    MsgBox(0,'Info','Data written to test.inf')
EndFunc

but it worked fine

but not in ur case

You are confusing yourself with what is actually happening.

When you type CR in an edit or Notepad or Scite, LF is automatically added. The same will happen with another edit in your GUI. It's not the SEND function which adds another LF it's the editor. This script below demonstrates that another edit box in the gui behaves the same as Notepad.

#include <GUIConstants.au3>

$add_note = GUICreate("Add Note", 524, 576, 271, 162)
$textbox = GUICtrlCreateEdit("", 8, 8, 505, 180)
$textbox2 = GUICtrlCreateEdit("", 8, 208, 505, 180)
$Button_Add = GUICtrlCreateButton("Add Note", 424, 424, 91, 41, 0)
GUISetState(@SW_SHOW)
$message = String("")
GUICtrlSetState($textbox,$GUI_FOCUS)

While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
        Case $msg = $Button_Add
                $message = GUICtrlRead($textbox)
                
                GUICtrlSetState($textbox2,$GUI_FOCUS)
                Send($message)
    EndSelect
WEnd

In Scintilla based editors (Scite, Notepad++) that Send($message) is displayed correctly, without the extra CRLF. Edited by Siao

Yes but like the effects in Notepad you need to understand why. "Correctly" is not the appropriate description here because both displays are correct, or both are wrong depending on what you think they should do, but actually they are just different.

In an edit box (which is what Notepad is) a LIneFeed character is added automatically when you type CarriageReturn.

The same happens in Scite.

When you read a line from an edit box it has CRLF at the end. When this line is sent to Notepad the CR generates a new LF and then the LF is entered so you get 2 LF's. So every time you copy a line from an edit and paste it into Notepad you get an extra LF. (I don't mean copy and paste like with a mouse drag which won't copy CRLF after the highlighted section.)

In Scite, which also adds a LF when CR is entered, the difference is that entering a line feed does nothing. If you send lots of LF characters to Scite followed by some text you will not see empty lines before the text. On the other hand, if you send lots of CR characters followed by a line of text then you will get empty lines. Since no LF was sent you could argue that this effect is incorrect. In Notepad or an edit box you will get empty lines both ways.

WOW :) fast responce!

At least its not just me. But the "Send(StringReplace($message, @LF, ''))" work sweet.

Nice work around SmOke_N, but I don't understand why it works - What does the @LF stand for?

For a multi-line edit box, you may only want the LAST @LF removed, not all of them. I would prefer:

Send(StringStripWS($message, 2)) ; 2 = strip trailing whitespace

:)

What you say is fine... @CR adds @LF but... @CRLF is adding @CR+@LF... however, it's actually adding another carriage return along with that line feed you say it is adding. It may not be an autoit bug, it may be a windows bug, but it certainly looks to be a bug to me.

Send() sends characters one by one. Program receives CR and converts that to CR+LF. It does not know that LF will follow next. Then it receives LF and converts that to CR+LF... all this to keep uniformity with the standard. So they would say "it's not a bug, it's a feature" :)

Tho the CR+LF concept as such is daft to begin with: two chars to express one thing - a new line.

This is true... hadn't stopped to think about that fact, but to be honest, I don't think I ever use "send" for anything to have noticed before. But something I wasn't aware of before this thread was that "Send" added chars to anything at all.
