Can’t figure out what you want to replace exactly (from the description) but based on the title and general idea I 'll give an example that you might modify to achieve your real goal:

I want to find lines starting with abc and change MISTeak later in the line to CORRECTED without changing anything else, using Replace dialog with Regular expresions:

Find: ^(abc.*)MISTeak

Replace: $1CORRECTED

^ start of line match only
( ) parens “capture” whatever is between them, you must write ( or ) if you need to match a real paren
abc – match literally abc
.* any characters, as many as are found including NONE.
MISteak : those literal characters (can be marked case sensitive or not)

$1 replace what you found in FIRST paren set, if you had () and () the $2 would be 2nd capture etc.

Save your doc, try it, use undo if you make a mistake and if you seriously foul it up reload the saved doc from disk.

Weakness (which can be fixed): What if MISTeak appears more than once in the line – there are ways to fix that too.

Two ideas:

If you have Line numbers enabled then clicking out there selects an entire line and allows you to easily drag mark multiple lines.

I didn’t know that until trying to answer your question so thanks for helping me learn something.

When I select in the FIRST column and drag it marks lines – it’s easy to mark just on line that way or a long section, but then thatn’s the way I have been doing it for years, maybe decades (How long has NP++ been around?)

@MAPJe71 Hi, you are quite right! Sorry for being such an IT-nitwit. But I will remember this for future questions, so thanks.

Wasn’t my intention to get anyone to do my job, but I have spend to many days searching how to work with Notepadd++ that I have run out of time (so I put in my time and effort to get it down, but I cannot get aquinted with npp so quickly).

I am really not good at forums and asking for help. I guess this was just a random panic reaction (also speaking the same language did it for me).
I just found out that I can delete my messages so I will do so in order not to disturb the topic that I am posting this on. But just for getting this out to you, I quickly put it here.

Thanks again and sorry for messing this topic up a little!

Bye

… or even looking for them with a web search.

Based on the data you posted, I’d say your file was the binary format rather than the ASCII format – you might want to see if you can configure it to output ASCII instead. If it’s a binary file, then likely no general-purpose text editor (be it Notepad++, MSWin notepad, vi, emacs, …) will be able to natively recognize it. It’s not an “encoding” issue, in the same way that UTF-8 vs ISO 8859 vs Win-1252 vs …

I think this question has nothing to do with Notepad++ (in that I think any other text editor – be it windows notepad.exe, vi, emacs, … – would give similar results when trying to open a binary file).

I just spent 5 minutes via search engines and https://www.openfoam.com, and couldn’t quickly find a description of the output format(s) available. Sorry, that’s all the time I have to devote to it.

My searches also revealed a forum at https://www.cfd-online.com/Forums/ . You may be able to post your question there: they might be able to help you either natively output to an ASCII text file, or to point you to a converter or post-processing manipulator to give you access to the coordinates.

Thank you for your answers, it work fine so.

Thank you, I appreciate your response. Will try to follow the steps suggested there and see what happens :)

As usual, I really appreciate the answers, thank you so much to both of you for the solutions, explanations.
The link to the other thread is invaluable as well to me, cheers for that.

@chcg what i mean is that i have to write a documentation about the bug and how i fix it , so i need to know the format and tha style that i have to follow because i have a project about notepad++ and i have to write how i fix it in a documentation

See https://github.com/bruderstein/nppPluginManager/issues/80. donho doesn’t like the ad of the server sponsor.

At least you could download if from https://github.com/bruderstein/nppPluginManager/releases and do a manual installation of the PM. Otherwise it should work as before.

Settings > Style Configurator > Style = Default Style, Font Style = [choose font from dropdown]

Are you using the 32bit or 64bit Notepad++?

If it’s the 64bit, my guess is that this thread will solve your problem.

Regarding being “verging on useless”: you do know that most apps, including Notepad++, have this File > Open dialog? Or that most (including Notepad++) have the ability to drag a file from an explorer window into the Notepad++ window, and it will automatically open it? Personally, I have Notepad++ almost always running, so it’s nearly as easy to drag the file as to right-click to open.

But you are right, having file associations work properly is nice (which is why, back in the XP days, I quickly learned how to manipulate file associations in the registry myself, so that I could fix it when greedy programs assumed you always wanted it to be the default for all the file types it recognized, or when I otherwise wanted to customize things).

If you aren’t on 64bit Notepad++, or if you are on 64bit but the other thread doesn’t help, please post more details: For example, please go to the ? > Debug Info..., click on copy debug info to clipboard, paste it into an empty Notepad++ tab, Ctrl+A to select all, TAB to indent, Ctrl+C to copy, and then paste it into your reply.
