"Find" in RichtTextEdit

[ds34]

I have a RichTextEdit and use it as a log application. I would like to add a "find/ find next" function for this log.

Anyone of you who has an idea of how-to or even sample implementation?

Cheers!

ds34,

Here is a example using _GUICtrlRichEdit_FindText - which is designed to do just what you want:

expandcollapse popup

#include <GuiRichEdit.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $lblMsg, $hRichEdit

Main()

Func Main()

    Local $sSearchTerm = "another"
    Local $iSearchStart = 0

    Local $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, 4) & ")", 320, 350, -1, -1)
    Local $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a line." & @CRLF & "And this is another line." & _
            @CRLF & "And yet another line.", 10, 10, 300, 220, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    Local $hFind_Button = GUICtrlCreateButton("Find", 230, 310, 80, 30)
    GUISetState()

    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                GUIDelete()
                Exit
            Case $hFind_Button
                If GUICtrlRead($hFind_Button) = "Find" Then
                    GUICtrlSetData($hFind_Button, "Again")
                    _GUICtrlRichEdit_SetSel($hRichEdit, $iSearchStart, $iSearchStart)
                    $iIndex = _GUICtrlRichEdit_FindText($hRichEdit, $sSearchTerm)
                    _GUICtrlRichEdit_SetSel($hRichEdit, $iIndex, $iIndex + StringLen($sSearchTerm))
                    $iSearchStart = $iIndex + StringLen($sSearchTerm)
                Else
                    GUICtrlSetState($hFind_Button, $GUI_DISABLE)
                    _GUICtrlRichEdit_SetSel($hRichEdit, $iSearchStart, $iSearchStart)
                    $iIndex = _GUICtrlRichEdit_FindText($hRichEdit, $sSearchTerm)
                    _GUICtrlRichEdit_SetSel($hRichEdit, $iIndex, $iIndex + StringLen($sSearchTerm))
                EndIf
        EndSwitch
    WEnd
EndFunc   ;==>Main

I hope that helps.

Thanks,

seems I should have made a move to the "new" GUIRichEdit.

However, this is not feasible, since the old GUIRichEdit I am using is way faster and this performance is critical in my case (lots of small, differently formatted text pieces to be appended to the RichTextEdit every second).

I will check the _GUICtrlRichEdit_FindText() if I can find a way to reuse/adapt this to the my version of "a" UDF (I do not even know the real version of this, since its an unversioned file from Gary Frost/Yoan Roblet I took from the forum ages ago).

I know it misses lots of finetuning/features (i.e. resizing support) compared to the new UDF, but again, the performance counts here.

Thanks again!

I tried to run this code directly, but get "ERROR: _GUICtrlRichEdit_FindText(): undefined function."

I also get the "undefined function" error when trying to use _GUICtrlRichEdit_FindTextEx and _GUICtrlRichEdit_GetTextRange in my own code. The functions are recognized by AutoIt's CallTips, leading me to think they are found. Yet other RichEdit functions work fine.

I can't figure out what the problem is. Any idea?

DickG ,

Any idea?

Which AutoIt version are you using?

The 2 additional commands you mention (_GUICtrlRichEdit_FindTextEx and _GUICtrlRichEdit_GetTextRange) are not in the current release - add the fact that you cannot use _GUICtrlRichEdit_FindText (which is) and it looks very much as though you are a little behind on the update front.

I'm using 3.3.0.0. So you're probably right about that being the reason.

I've been putting off updating because I might have to spend time debugging those that break due to the changes. So I'll just have to bite the bullet and update.

DickG,

Good luck to you with the updating - it will be worth it.

I would wait until after Xmas though, or your dinner is likely to be overcooked and you might miss Santa!

I bit the bullet and updated all my scripts. Luckily, not that much needed changing. All went well.

But now AutoIt can't find these commands:

o _GUICtrlRichEdit_GetBold

o _GUICtrlRichEdit_SetBold

o _GUICtrlRichEdit_SetOLECallback

o $ES_SUNKEN as parameter to _GUICtrlRichEdit_Create

I searched the forum and the Help file, but can't find anything about them. Were they deleted? Is there a replacement or workaround?

OK, I did more digging and discovered how to handle the bold (_GetCharAttributes and _SetCharAttributes). No problem on $ES_SUNKEN: I just deleted that.

The only problem I have is not being able to unbold text after bolding it.

I'm using _GUICtrlRichEdit_SetCharAttributes($hwnd, "+bo", True) to make it bold and _GUICtrlRichEdit_SetCharAttributes($hwnd, "-bo", True) to try to unbold it, but "-bo" doesn't do it.

Well, anyway, hope you have a great Christmas and New Year, Melba. And thanks for your help.
