Yeah, regex's are incredibly handy when manipulating text. I use 'em all the time, much better than the finicky parsing code i used to write. Fortunately, C# / .NET has reasonably good support for them. The one you're looking at will strip off everything after php in the input string.
FWIW, i use this[^] for testing them.

So Real programmers don't use RegEx.

It finds a colon, followed by two slashes, followed by 0 or more occurrences of any character, then replaces that with an empty string. In the example case, the preg_replace() function returns "php".

What part of the web development forum don't you understand? Not just a programming question but a PHP regular expression question. Sheesh.

"Web development" is too generic of a term, and since I wasn't really talking about *code*, where do ya go?
I was merely asking what the regular expression would do given the string it was being applied to. Regular expressions certainly aren't restricted to web development. CP doesn't have an appropriate forum selection for these kinds of questions. I really don't know why Chris moved this to the C# forum as it's not about C#, or even about PHP (no forum available).
I was surprised to find out there is a book about regular expressions, so maybe we should have a forum for that topic alone.

It could fit in any number of programming forums, but it does go in a programming forum. Where does a question about converting between C# and C++ go? I'm not sure, but it's not the lounge. If the regulars can't get it right how can we expect the new users to get it right.

Don't you think I considered all this before posting in the lounge? I was careful not to talk about coding, so as far as I'm concerned, you're in error, and I "got it right".
For what it's worth, it took 15 minutes to get an answer. I posted a php-specific question in the "Web Development" forum several hours ago, and as of this writing, nobody has responded. A lot of good it did me to post it there, eh?

When is that ever not the case.  You should have worked *gotten* in there though.

Well, I wouldn't expect much php help from CP anyway.
This is really pointless quibbling given that the post has already been moved, but I don't see how the question is any different then asking about some combination of ShowWindow flags. It's a parameter in an api method in both cases.

/\:\/\/.*/ becomes /://.* after you take out the escapes
.* = any character, any number of times
so it replaces the string /:// followed by any number of any characters by ""
Looks like the initial "/" is superfluous. Regular expressions can be specified by /expression/ - so be careful.
Assuming the "/" is a mistake, it would just chop off everything after "php".
Next time hit the right forum please. It lessons the impact of your vitriol on others who post programming questions in the lounge otherwise.

I think my original post straddled the line between a programming question and not a programming question, since it was merely asking what the results would be of a regular expression.
So what is the right forum for regular expressions? In my case, CP doesn't have a PHP forum, so I'm out of luck there. It certainly isn't necessarily C#, or C++.

John, I feel your pain. There's an O'Reilly book called Mastering Regular Expressions, or something like that. It's a great book, especially as it covers most common flavours of regex, making it invaluable for situations like yours. I highly recommend it.

Is that your way of saying that you don't understand it?

Can you hack numericupdown's to change the arrow button's width? or do you have to make one from scratch if you want bigger buttons?
|
|
|
|
|
You won't be able to hack the arrow button's width. The method PositionControls() in the UpDownBase class determines it's width. This class is private and would override any possible hacks.
Your best option would probably be to build a UserControl using a TextBox and two Buttons.
Take care,
Tom

Hi to all, I work on an application that takes measurements from a piece of hardware, and
then manipulates it.
my problem is that while collecting the measurement my program gets stuck, meaning if I do something else on my PC at the same time, when I return to my form it is blank.
I understand it's a matter of threading.
the problem is I can't call my callback function passed to the new thread with the ProgressBar parameter.
my Form creates a ProgressBar that my collecting function is supposed to operate, but it can't.
I get the error,
Cross-thread operation not valid: Control 'progressBarSampling' accessed from a thread other than the thread it was created on.
What I want to achieve is to be able to pass the Form's progressbar as parameter to my function
so it can use it.
Any help will be most appreciated.
regards.

You might want to take a look at the BackgroundWorker class. This will help you immensely.
Deja View - the feeling that you've seen this post before.

What do you mean by that?
that I should look for global information about the class?
|
|
|
|
|
I mean that if you search through that mystic portal called google on BackgroundWorker and take a look at some of the samples and articles, you'll see how this works and how it might help to solve your issue.

The reason I asked you is because I thought maybe you are trying to direct me to problem specific
solution and not such a global shot in the air.
as far as I know, and I don't know much on that subject, a background worker only means it a thread that works in the back, how is that supposed to solve the problem of passing a form component to a
thread other then the one that created it, I don't know, but I am reading some material about that.
if you could direct me to some more problem specific information I will be most grateful.

Read up on the BackgroundWorker[^] class and it will be come clear. It gives you the option of reporting progress to your UI thread.

thanks I'll catchup on that
