      Guy, here the updated one.
      A “one-selection” action results in opening the standard replace dialog behavior.
      A “two-selections” action, even with an empty one, results in modifying the fields.
      I see it as a benefit that you are able to decide that only one of the fields should be filled
      and the other should be empty in any case.

      import ctypes
      from ctypes.wintypes import BOOL, HWND, LPARAM
      
      WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND, LPARAM)

        Hello, @claudia-frank, @Scott-sumner, @pouemes44, @go2to, @jorge-campos, @herofiles, @azjio-azjio, @alan-kilborn and All

        Thanks to @claudia-frank, this present topic and the discussions, below, about multi-lines search AND multi-lines Replacement :

        https://notepad-plus-plus.org/community/topic/13823/replace-function/1

        https://notepad-plus-plus.org/community/topic/13684/feature-request-textarea-search-replace/1

        have, now, an ELEGANT solution, with her Python’s script, just above !

        You just need to be able to do multiple selections ( Option Settings > Preferences… > Editing > Multi-Editing Settings > Enable CHECKED )


        BTW, the upper limit of 2046 characters, in the Find what: box of the Find/Replace dialog, only, could be by-passed, easily :-). Indeed, just use the Regular expression search mode and use the generic regex (?s)Left-boundary.+?Right-boundary !

        For instance, you can choose a particular character, which does not exist,yet, in your file(s) to be modified, and build the regex :

        (?s)(#####\R).+?\1

        This regex contains any non-null amount of characters between TWO same complete lines #####, with their line-breaks

        So :

        • Do a normal selection of this regex (?s)(#####\R).+?\1, using the mouse

        • Then, with a Ctrl + Left Click action, simply, select your Replace block, multi-lines or not

        • Run the Claudia’s script above

        => Immediately, the Find/Replace dialog pops-up and :

        • The Find what: box is filled with the regex (?s)(#####\R).+?\1

        • The Replace with: box is filled with the block of text, which must replace the searched text

        Best Regards,

        guy038

        P.S. :

        @claudia-frank, I understand your point of view. Your script is quite flexible :-D. For instance, I was able to :

        • First, do a Ctrl + Clic selection of a multi-lines block of text

        • Run your script => Find what: box empty and Replace with: box filled with that multi-lines block

        • Select an second file, containing the text (?s)(#####\R).+?\1

        • Do a normal selection of that regex

        • Run again, your script => The find.Replace dialog, presently in the background, is, then, updated with this regex, filled in the Find what: box

        • Select a third file, containing the ##### boundaries lines

        • Perform the S/R on the contents of this third file

        Et voilà !!

        Many thanks, again, for this very, very, valuable script, indeed !!!

        Hum… Already 3 h 25 !! I’d better go to bed : working tomorrow !

          It would be nice if the author would make an additional window when the button is clicked

            The external program is working. I make a plugin and no longer works (EnumChildWindows).

              Sorry, but what are you try to tell us?
              Which external program and which meaning has EnumChildWindows API in this context?

                I wrote a program for the test of regular expressions. It serves as a database. When you click a button, it fills in the search and replace fields.
                I decided to make a plugin that will do the same. But the same program (exe and dll) work differently. EXE fills the fields, but the DLL can not fill.
                I tried using EnumChildWindows to find the elements of the window, as is done in the examples above. But as a result, he found only 3 elements.
                0 hwnd = 725602 Class = Button Title = Caption
                1 hwnd = 2233572 Class = Static Title =
                2 hwnd = 1707882 Class = SysTabControl32 Title = Tab1

                  without seeing/understanding the actual code it is hard to say what might be the issue
                  but, personally, I would not recommend using EnumChildWindows when trying to find a
                  dialog control window handle, instead use GetDlgItem.

                      be careful about searching for the ordinal only, as every dialog uses it.
                      https://docs.microsoft.com/en-us/windows/desktop/winmsg/about-window-classes
                      Most plugins and internal npp windows are dialogs.

                        I know it. I do not set the window class. I have no way to change this. The external program, as I said, works.

                          Sorry, didn’t recognize the update.
                          Windows, sometimes, treats retrieving external and internal information differently.
                          Means, something you retrieved from an exe might differ from something
                          you want to retrieve within its own process.

                          In python, I would it do like this

                          import ctypes
                          user32 = ctypes.WinDLL('user32')
                          hwnd = user32.FindWindowExW(None, None, u'#32770', u'Replace')
                          hwndEdit_1 = user32.GetDlgItem(hwnd, 1601)
                          hwndEdit_2 = user32.GetDlgItem(hwnd, 1602)
                          

                          This takes care that only the dialog with name Replace is found.

                            I have done just that. Keyword only “Extended”. But using AutoIt3

                            $hWnd = WinGetHandle(“[CLASS:Notepad++]”)
                            If Not @error Then
                            If BitAND(WinGetState($hWnd), 16) Then WinActivate($hWnd)
                            _SendMessage($hWnd, $NPPM_MENUCOMMAND, 0, $IDM_SEARCH_REPLACE)
                            $hWnd = WinWait(“[CLASS:#32770]”, “Extended”, 2)
                            If $hWnd Then
                            ControlSetText($hWnd, “Extended”, “Edit1”, _GUICtrlRichEdit_GetText($hRichEdit_SPE))
                            ControlSetText($hWnd, “Extended”, “Edit2”, GUICtrlRead($PtnRep))
                            ControlCommand($hWnd, “Extended”, “Button18”, ‘Check’) ; 18 - regular expression (16 - normal)
                            EndIf
                            EndIf


                            on PureBasic code is the same for exe and dll. Search window “#32770” starts at the top, so it does not cause a problem. There are either no such windows or they are below.

                              Maybe I have a wrong assumption what you are actually doing.
                              When you talk about an exe I assume that this is a different standalone program, correct?
                              When you talked about dll I assumed that this might be a npp plugin.
                              Now I get the feeling this is incorrect. Would you mind to explain what exactly is what
                              and what your ultimate goal is?

                                Thank! The previous code helped. I saw in it the absence of a handle in FindWindowExW(None
                                I am intensively writing 2 plugins

                                  As a result, several plugins, but there is much to strive for.
