    But the search dialog should be open



  • @AZJIO-AZJIO said:

    But the search dialog should be open

    I was most interested in the part that does the opening of the search dialog and switching its active tab. I had tried to do something like that in the past and didn’t have good luck. I can’t remember if it was for the same reason I am now having trouble with your original script, or not, but it very well could be. Do you know if there is an alternate way of doing it that might be more reliable?



  • Add before each command Sleep (1000) to see which command has failed



  • If it is still about the status message, then be aware that it is ownerdrawed text,
    which means that you need to resolve the pointer returned by the statusbar message used.
    Well, I assume ControlGetText returns the message from SB_GETTEXT (never really used autoit).

    A python script to get the text would look like this

    #!/usr/bin/python
    # -*- coding: utf-8 -*-

    The script opens the find dialog, then gets the window handle from that dialog,
    enumerates all its child windows (aka controls) and if a statusbar control has been found,
    simulates an button press on Count button and writes the statusbar message to the console.

    Using Au3Info.exe, check CLASS: # 32770



  • @Claudia-Frank

    Once again you are amazing! I haven’t tried what you propose yet but I have no doubt it will be awesome.



  • @Claudia-Frank

    I started working with and extending your script to do some other things on the Find dialog. I can get and set the state of radio buttons and checkboxes–yay! Some final things that I need to do are to get and/or set the text of the Find-what and Replace-with edit boxes (or comboboxes?). Is there a best way to do this? It isn’t as easy as with the other controls because these don’t have a caption. Can you post a short example of how to get text and set text to these edit controls on the Find dialog?



  • @Alan-Kilborn

    Hi Alan,

    you right, edit box aren’t easy to identify but, as far as I remember, you can rely on the order (z-order) how the controls get identified/returned.

    So in this case you could check when the static box (aka label) returns with &Find what and set a
    flag and when the edit control appears, check if flag is set and treat it. To retrieve or set the text
    you can use the api functions GetWindowText and SetWindowText.

    A simple example like this (only the callback part and the definitions of the code)

    GetWindowText = ctypes.windll.user32.GetWindowTextW
    GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
    SetWindowText = ctypes.windll.user32.SetWindowTextW
    
    STATUSBAR_HANDLE = None
    FIND_WHAT = None
    REPLACE_WITH = None
    
    
    def EnumCallback(hwnd, lparam):
        global STATUSBAR_HANDLE
        global FIND_WHAT
        global REPLACE_WITH
        
        curr_class = ctypes.create_unicode_buffer(256)
        GetClassName(hwnd, curr_class, 256)
        
        length = GetWindowTextLength(hwnd)
        buff = ctypes.create_unicode_buffer(length + 1)
        GetWindowText(hwnd, buff, length + 1)
        
        if curr_class.value.lower() == 'msctls_statusbar32':
            STATUSBAR_HANDLE = hwnd
            # return False
        elif curr_class.value.lower() == 'static':
            if buff.value == '&Find what :':
                FIND_WHAT = True
            elif buff.value == 'Rep&lace with :':
                REPLACE_WITH = True
        elif curr_class.value.lower() == 'edit':
            if FIND_WHAT:
                SetWindowText(hwnd, u'xyz789')
                FIND_WHAT = False
            elif REPLACE_WITH:
                REPLACE_WITH = False
                SetWindowText(hwnd, u'123abc')
        else:
            console.write('{}({:^7}) : {}'.format(curr_class.value,hwnd, buff.value) + '\n' )
        return True

  • So the ideas presented here by @Claudia-Frank I think will allow me to stop using AutoIt in favor of Pythonscript for controlling the Find dialog functions. It seems very nice. To bring this thread back to where it began, here’s a P.S. based upon Claudia’s work that puts the current selection (which can include multiple lines) into the Find dialog’s Replace-with box. The part of it I question for general usage is the .decode('utf-8') – it seems to work for me, but I’m not an encoding expert by any means.

    Here’s ReplaceWithBoxFromSelection.py :

    import ctypes
    from ctypes.wintypes import BOOL, HWND, LPARAM
    
    WNDENUMPROC = ctypes.WINFUNCTYPE(BOOL, HWND, LPARAM)
    
    FindWindow = ctypes.windll.user32.FindWindowW

    GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
    SetWindowText = ctypes.windll.user32.SetWindowTextW
    create_unicode_buffer = ctypes.create_unicode_buffer
    
    replace_tab_caption  = u'Replace'
    replacewith_caption = u'Rep&lace with :'
    replacewith_is_next_ctrl = False
    replacewith_handle = None
    
    def EnumCallback(hwnd, lparam):
        global replacewith_is_next_ctrl
        global replacewith_handle
        curr_class = create_unicode_buffer(256)
        GetClassName(hwnd, curr_class, 256)
        length = GetWindowTextLength(hwnd)
        buff = ctypes.create_unicode_buffer(length + 1)
        GetWindowText(hwnd, buff, length + 1)
        if curr_class.value.lower() == 'static':
            if buff.value == replacewith_caption:
                replacewith_is_next_ctrl = True
        elif curr_class.value.lower() == 'edit':
            if replacewith_is_next_ctrl:
                replacewith_handle = hwnd
                return False  # stop enumeration
        return True  # let enumeration continue
    
    def main():
        msg = ''
        if editor.getSelections() == 1 and not editor.getSelectionEmpty():
            sel = editor.getSelText()
            if len(sel) > 2046:
                sel = sel[:2046]
                msg += 'Warning:  Selected text too long for replace-with box; truncating to 2046 characters.  '
            notepad.menuCommand(MENUCOMMAND.SEARCH_REPLACE)
            find_dialog_hwnd = FindWindow(None, replace_tab_caption)
            if find_dialog_hwnd:
                EnumChildWindows(find_dialog_hwnd, WNDENUMPROC(EnumCallback), 0)
                if replacewith_handle:
                    if SetWindowText(replacewith_handle, sel.decode('utf-8')) == 0:
                        msg += 'Error:  Problem setting window text'
                else:
                    msg += 'Error:  Bad value for replacewith_handle'

    main()


  • @Scott-Sumner

    The part of it I question for general usage is the .decode(‘utf-8’)

    I assume your way should work, regardless of the encoding used by the user,
    if I understand scintilla and pythonscript plugin correctly.
    editor.getSelText() always returns a byte string (python str) but, because we defined
    unicode version of SetWindowText, this string needs to be converted as you did.
    Maybe I’m wrong.

    Cheers
    Claudia



  • @Claudia-Frank

    I did notice something else that was a bit odd (and drove me a little nuts until I figured out what was going on) when I was working on that script. Let’s see if I can describe it. Usually I work with English_customizable.xml loaded, and everything is consistent and as-expected. When working on that script, I switched back to English.xml, thinking that if I share the script here, it should not use my specific and custom Find dialog captions, but rather the generic English ones.

    With English configured, I noticed that when Notepad++ starts up, it doesn’t exactly have English.xml set up, it has something close to it, but not exactly! I found that if I go back into the Preferences, and again select English from the dropdown (even though it is already selected), and have the Find dialog up at the same time, I can watch subtle changes occur in the Find dialog’s label/caption fields. For example, and I can watch a space be inserted (or removed) between “Find what” and the colon that follows (same for “Replace with”. I really have no idea why this is happening. Again, this only happens with English.xml, not English_customizable.xml.

    The reason it was making me crazy was that I’d work on the script, have it working fine, then later I would notice it was breaking because it couldn’t find the controls. I kept changing the text strings to make it work and then later it would break again.



  • Hello, @scott-sumner and @claudia-frank,

    Claudia, your automatic counting of any normal selection, multi-lines or not, works fine !

    Scott, your ReplaceWithBoxFromSelection.py script is working nice, too !. I’ve just noticed that your script, automatically, copies the current normal and unique selection, BOTH, in the Find what : and in the Replace with: boxes. Is it the normal behaviour or am I wrong about it ?


    This topic makes me think about an other possibility ! Let’s suppose that the option Settings > Preferences…> Editing > Multi-Editing Settings is enabled

    Now, the goal would be :

    • To define TWO selected blocks of text, which could, independently, include multiple lines

    • To Write a Python script which :

      • Opens the Find/Replace dialog

      • Writes the first user selection, in the Find what: box

      • Writes the second user selection, in the Replace with: box

    Scott and Claudia, what is your feeling about it ?

    Best Regards,

    guy038



  • @Scott-Sumner and @guy038

    Scott, I discovered something similar but thought it was related to using npp with wine.
    If I open the find dialog and then switch from english to english_customizable and back
    to english I loose the >> from “find next” button and the underscores (ampersands in text)
    for the “count” and “find all in all opened documents” buttons.
    I don’t see it as an issue as you normally set this once and done, but I see why it bothered you. ;-)
    I have a shortcut to “Run Previous Script” which I use quite often.
    What happens from time to time is that I execute another script while editing
    the “current” script and then when I use the shortcut I assume that the current script
    should be executed, which isn’t the case as another script was executed in between.
    First thought I have in such a case is always, damn - what did I miss why isn’t it working anymore? What did I broke?
    Checking the source again and again just to find out that haven’t executed the script. :-)
    You see - seems to be “normal” programmer behavior ;-)

    Guy, haven’t check it yet but I guess it should be easy to implement, yes.
    If Scott, or anyone else hasn’t proposed a solution, I will give it a try in 10-12 hours.
    Need to leave now.

    Cheers
    Claudia



  • @guy038 said:

    copies the current normal and unique selection, BOTH, in the Find what : and in the Replace with: boxes

    Hmmm. Yes, that is what it does but that was actually UNINTENTIONAL! I guess I didn’t notice because for years I have had an AutoIt script which does just that behavior. A lot of the time when doing replacements, I’m just doing a minor adjustment to the text I am finding, so it saves time to have both the Find-what and Replace-with fields initally set to the same data. I just make my minor tweak to the replace-with part and I am off to the races.

    In this thread’s script (ReplaceWithBoxFromSelection.py), however, I believe this happens due to the normal invocation of the Replace command (with notepad.menuCommand(MENUCOMMAND.SEARCH_REPLACE))–when a selection is active, Notepad++ on its own puts the selected text in the Find-what box. Perhaps that is less than desirable here in this script. :(



  • @guy038 said:

    I like your idea and it should be easy, but I will defer to Claudia as I am extremely busy at the moment. :-D



  • Hi, @scott-sumner and @claudia-frank

  • @guy038, @scott-sumner

    Hi Guy,

    sorry, family celebration was a bit longer than expected.
    Just did the script and some basic tests and discovered that encoding
    is an issue like Scott already mentioned.
    Will try to find a way to make it work regardless which encoding is used.

    Cheers
    Claudia



  • Hi, @claudia-frank,

    Don’t worry, Claudia and just enjoy these family’s moments ! Luckily, we, all, own more valuable things than Notepad++ and some Python scripts :-D

    …I’m just thinking about actualities and the death’s celebration of Helmut Kohl. Thanks to him and some important European women and men, we all enjoy, in Europe, a peace period, of near 75 years ! and THIS, it’s a basic point !!

    Best Regards,

  • Hello, @claudia-frank,

    What to say else ? Just wonderful and awesome, indeed !!!

    I already tested the case of rectangular selection(s) and the upper limit of 2046 characters => No problem, it acts as expected :-)


    Now, as always, when building a program, there’s a small bug with the lower limit of 0 character !

    I, successively, tried to make an empty search selection, then an empty replace selection and, finally, both search and replace selections empty.

    Note : To obtain, physically, a zero-length selection, I just select one character with the mouse, then move back the mouse, with a possible hit on the CTRL key, to only get the caret

    • If both selections are empty, the message Error: Either empty selection or unsupported selection mode detected occurs, as expected. Nice !

    • If, ONLY, the search selection is empty, the Find/Replace opens normally. May be, in that case, Claudia, a message would be better !

    • If, ONLY, the replace selection is empty, the Find/Replace opens normally, with the Find what: box filled and the Replace with: empty. That the expected behaviour, in order to delete all the search blocks of text found

    I also noticed that if I Ctrl + click and select some text, ONLY, it is, logically, inserted in the Replace with box, leaving the Find what: box empty :-D

    But, if I, simply, click, without the Ctrl key, and select some text, the message Warning: Only two selections are possible. Received:1 occurs. However, Claudia, I think it’s a valid case.

    So, in the case of a normal selection 0, only, the Find/Replace dialog should pop up and contain :

    • A Find what: box, filled with the selection contents

    • A Replace with: box, wiped out of any [previous] character

    P.S. :

    I found out something weird, but logic : If I build a one-line rectangular selection, this selection is correctly written in the Find what: box !!
