      Love the product, but curious to know if it is possible to execute the “Find in Files” from the command-line / batch / vbscript.

      The output seen within N++ is something I like and I’d like to incorporate this output for some automated tasks if possible.

      Cheers, Cam.

        not 100% sure what you want to achieve.

        Do you have some automated tasks while npp is not running at all
        and at some step you do want to search something in files and the
        output should be similar to the one npp shows

        or

        do you have npp running, do something and then you want to run
        find in files dialog and this output should be forwarded to
        some automated task?

        Maybe you wanna describe in more detail what exactly you want to do.

        Cheers

          I also am not sure what @Cameron-Young is really wanting to do, but it got me to thinking about how to handle Find-in-Files output programmatically “within” Notepad++ via Pythonscript.

          I came up with the following that will get the textual contents of the Find result panel (based upon the code ideas here–a pretty shallow rip-off in fact!). This could be prefaced with setting the Find dialog’s control fields and pressing the Find-in-Files (or Find-All-…) button (pressing a button example here) under program control. Once you have the output text, it can be parsed at will to do whatever is needed from that.

          Here’s FindResultPanelGetText.py:

          import ctypes
          from ctypes.wintypes import BOOL, HWND, LPARAM
          WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND,LPARAM)
          FindWindow = ctypes.windll.user32.FindWindowW
          GetWindowText = ctypes.windll.user32.GetWindowTextW
          GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
          EnumChildWindows = ctypes.windll.user32.EnumChildWindows
          GetClassName = ctypes.windll.user32.GetClassNameW
          curr_class = ctypes.create_unicode_buffer(256)
          
          find_result_panel_complete_text = ''
          
          def foreach_window(hwnd, lParam):
              global find_result_panel_complete_text
              length = GetWindowTextLength(hwnd)
              if length > 0:
                  buff = ctypes.create_unicode_buffer(length + 1)
                  GetWindowText(hwnd, buff, length + 1)
                  if buff.value.startswith('Search "'):  # perhaps change to more rigorous test...
                      find_result_panel_complete_text = buff.value
                      return False
              return True
          
          EnumChildWindows(FindWindow(u'Notepad++', None), WNDENUMPROC(foreach_window), 0)
          editor.copyText(find_result_panel_complete_text)  # result in clipboard

            nice one and could be already half the solution. :-)
            Maybe we should think about python_automation_api_for_npp ;-)

            Cheers

              python_automation_api_for_npp

              Maybe not an all-encompasing automation API, but one focused on the ever-controversial Find functionality…
              Are you up for a joint project with me on this?
              :-D

                in general yes, but not for the moment, currently I’m doing 3 projects in parallel
                And I don’t see that this progresses. :-)

                Cheers

                  This is a real necropost at roughly 6.5 years later, but I wanted to post an updated version of the earlier script made by @Scott-Sumner ; one that just feels a bit less hackish (sorry).

                  I call this variation SearchResultPanelGetText.py:

                  # -*- coding: utf-8 -*-
                  from __future__ import print_function
