Append text to the last line of an editbox

10 posts in this topic

Hi guys,

is there a simple (or even a complex :whistle: ) way to append text to the end of an edit box, regardless of the caret position? I want to be able to do this without scrolling down to the bottom as I want to be able to append some text while the user is looking at the top of the edit box.

I currently use the following code to append the text:

GUICtrlSetData ($logCtrlId, $text & @CRLF, 1)

Right now, if the user clicked somewhere on the Edit box, changing the caret position from the end to some other part in the middle of the text, the next time I append some text it is added where the caret position is. Instead I'd like to always append the text to the last line of the edit box.

Is this possible?

Thanks,

Angel

I would think this would work:

GUICtrlSetData ($logCtrlId, GUICtrlRead ($logCtrlId) & $text & @CRLF, "")
That would just overwrite the contents of the control with the old contents plus the new string, right? The problem is that it seems that that would change the "position" (the scroll) so the user could not be reading the contents of the edit box while the script is updating it. Also, the edit box contains a huge amount of data, and is updated constantly, so I fear that the performance of the GUI would be pretty bad if I did that...

The solution that I am looking for is to have some way of moving the caret to the end of the editbox and then appending the new data into the edit box as I was doing before.

I know that you can change the caret position using one of the EditBox User functions, but I don't konw how to get the position of the last line in the edit box. Is there some way to do that?

I don't see you being able to do that without something like ControlSend()... and I've not tested that either.

Edit:

Looks like there's a function for everything but _GUICtrlEditAddLine :whistle: Ohhhh Gary ... :)

Where did you see that function? I can't find it in the "GuiEdit Management" section of the User Defined functions in the help file of the latest version (v3.2.0.1)!

To get the last line you can used _GUICtrlEditLineCount($h_Edit)

AutoIt Scripts:NetPrinter - Network Printer UtilityRobocopyGUI - GUI interface for M$ robocopy command line

Sorry, I did not understand you. As you can guess English is not my first language! :P

I managed to do this by using _GUICtrlEditLineCount. I'll try to post the solution tomorrow (hopefully I'll remember!). But I did not manage to avoid the control from scrolling down :nuke:

It is true that it seems that a _GuiCtrolEditAddLine is missing!

Thanks for the help!

Hate to revive a long dead thread (6 months, eep), but I'm having similar troubles with the very same thing, and was wondering if Angel (or anybody else for that matter) may have come up with something. I'm currently trying something along the lines of:

$end = StringLen(GUICtrlRead($editCtrl))
_GUICtrlEditSetSel($editCtrl, $end, $end)
GuiCtrlSetData($editCtrl, $line & @CRLF, 1)oÝ÷ Ùhbr(®Kw­¡§^·!÷n®)තg­«bú+«b¢x¬mè§

#include <GUIEdit.au3>
GUICreate('', 400, 300)
$buttonCtrl = GUICtrlCreateButton('Click', 0, 0, 40, 20)
$editCtrl = GUICtrlCreateEdit('', 0, 20, 400, 280, BitOR($GUI_SS_DEFAULT_EDIT, $ES_READONLY))
GUISetState()

While 1
    $gm = GUIGetMsg()
    Switch $gm
        Case $buttonCtrl
            GuiCtrlSetData($editCtrl, '')
            For $i = 1 to 200
                $end = StringLen(GUICtrlRead($editCtrl))
                _GUICtrlEditSetSel($editCtrl, $end, $end)
                GuiCtrlSetData($editCtrl, 'Line ' & $i & @CRLF, 1)
                Sleep(10)
            Next
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

If you run that script, then click the "Click" button, and then try to click and drag in the edit control while it's writing, you'll see that it will overwrite some of the output.

Gary really does need to make a GUICtrlEditAddLine. :whistle:
