See here: Fast Search and Replace in Large Number of Files: A Practical Guide[^]
Hello all,
My name is Dr. Brian Hart, and I am a PhD astrophysicist and one of the original users of The Code Project from back in the year 2000. I've written many articles in C++ and C# programming.
I just wanted to share a link to an article I just posted, today, on The Code Project. I hope you will stop by and take a look.
It's about using memory-mapped files in C# to do a search and replace a large number of files fast. I implemented the algorithm both as a (really bare-bones) console application and a more graphical/user-friendly Windows Forms tool.
It came out of work that I was doing on this .sln file that contains almost 1,000 projects in Visual Studio, and I was pushing my existing Find In Files / Replace In Files tools to the limit. I needed to write my fast algorithm as part of a file- and project-renaming tool I was writing, partly to manage the refactoring of so much code.
The code included with the article compiles (after doing a nuget restore in the Solution directory). It should be informative and a great example of processing a huge number of files really fast.
The impetus of the article was trying to imitate the speed with which Notepad++ processes files with its Find in Files and Replace in Files operations.
I also include code to create a progress dialog in WinForms and report the operation's progress to the user while keeping the GUI responsive. I hope it helps someone with their programming work!
Regards,
Brian Hart

Don't do this.
There is already a feed of recently posted articles[^], and multiple newsletters which list the recently posted articles. Anyone who is interested in the topic will see your article there and read it.
Recent articles are also posted on the CodeProject Twitter feed, for those who still use that site.
Posting in The Lounge to promote your new article stinks of spam / rep-point hunting. Imagine how useless the forum would become if every author did this!
You think it's annoying having a daily Wordle thread? Having page after page of "Check out my new article", "No, check out MY new article", "My new article is better than your new article"" etc. threads would be a thousand times worse.
And it's not going to achieve much. By this time next week, your article promotion post will be buried on page 42, where nobody is ever likely to see it.
So seriously, don't do this.

And yet he gets 4 up-votes.

I'm holding off with the spam vote, but the article points to a youtube channel and states that the author may be offered incentives for pointing people to that channel.

Good spot! Probably worth flagging that up to @sean-ewington for review.

Full disclousre: I am a fan of that youtube channel, but I was just mentioning it as opposed to sponsoring it per see. I was just wanting to be transparent an honest. However, I did the R&D of the article myself, and it's my own original work! And I do think that the person on the YouTube channel has good things to say in regard to optimizing the performance of C# software.
It's kind of like CNN reporting on something their parent company does, and then saying, "Oh and by the way, CNN is owned by Warner Bros/Discovery." I'm all about being honest and transparent, but I am not above asking the person who is behind said YouTube channel if they want to enter into a mutually beneficial arrangement.

I get where you're coming from and all and ain't nothin' round here even if I've been around a long bit too.
But...
The guy's been here ~25 years, so it's playing the long game just to be a spammy spammer.
Pretty impressive bio. He probably doesn't drink, but if we had looser legal definitions around kidnapping and controlled substances then chucking him into a van and pumping him full of loose lips might get real interesting real fast.

Cool accolades bro. But how does this come into play in relation with the article you're trying to promote?
|
|
|
|

Nothing. It's just a crass attempt to puff myself up and make myself seem smarter than I really am (or so some of my friends think). 
It's just me introducing myself. Probably a lot like this guy[^].
Ha ha ha...

Brian Hart

Got to the bit about Notepad++ and cackled because I'd been thinking up to there, "man, Notepad++ is really good at that..."

I see what you did there.
But then, doing so killed the cat.

Down here on Earth! π΅
