  • Is "for(;;)" faster than "while (TRUE)"? If not, why do people use it?

    - by Chris Cooper
    for (;;) { //Something to be done repeatedly } I have seen this sort of thing used a lot, but I think it is rather strange... Wouldn't it be much clearer to say while (TRUE), or something along those lines? I'm guessing that (as is the reason for many-a-programmer to resort to cryptic code) this is a tiny margin faster? Why, and is it REALLY worth it? If so, why not just define it this way: #DEFINE while(TRUE) for(;;)

  • Mod_rewrite and redirects with training forward slash not working

    - by john williams
    I'm using the following lines of code in my .htaccess file to create redirects. The problem is, whenever I go to example.com/register/ it cant find the css files because it's looking for example.com/register/mycss.css instead of example.com/mycss.css. Redirect 301 register.php http://example.com/register RewriteRule ^register/?$ register.php How can I correct this? I'm new to any kind of htaccess/mod_rewrite functions so feel free to point me in the right direction if there are any other flaws.

  • Displaying Data on the Form with C#

    - by The.Anti.9
    I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar. What is the best form control to help me display this data neatly?

  • Visual Studio line deletion

    - by Sean
    Is there any way in Visual Studio 2003 that I can delete a line without it being copied into the clipboard? There are instances when I want to copy the first line of a block of text and then delete the following n lines but this then puts the last line I deleted into the clipboard, which is very annoying. I have come from a brief keymap background and I could easily do this with Alt-D. And while I'm on the subject, why on earth have MS stopped supporting the brief keymap?

  • Calling overridden method from within overriding method in OO PHP

    - by paddymcc
    Working in a symfony model, I want to override a function and call the overridden function from within the overriding one, along the lines of class MyClass extends BaseMyClass { function setMyProperty($p) { parent::setMyProperty($p); //do some other stuff } } This is resulting in a segmentation fault. I don't want to alter the parent class - it's been generated by symfony, and may feasibly be overwritten in the future if the model is rebuilt. This seems like something that should be straightforward, but I'm struggling to find the solution. Thanks for any advice

  • Which JavaScript graphics library has the best performance?

    - by DNS
    I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority. The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one. Has anyone done a performance comparison between any of these?

  • Get string value from http response with Mechanize

    - by Gearóid
    Hi, I'm currently integrating facebook into my current app and I've succeeded in retrieving the access_token using the following code: url="#{url}?#{client_id}&#{client_secret}&#{code}&#{redirect_uri}&type=client_cred" agent = Mechanize.new page = agent.get(url) The page object above has a body which contains text something along the lines of access_token=XXXXX I just want to pull out the access_token value. I can get the entire string simply by writing: page.body But I was wondering is there a way to get the access_token value without resorting to regular expressions etc? Thanks.

  • Python equivalent of C++ getline()

    - by Arnab Sen Gupta
    In C++ we can enter multiple lines by giving our own choice of delimiting character in the getline() function.. however I am not able to do the same in Python!! it has only raw_input() and sys.stdin.readline() methods that read till I press enter. Is there any way to customize this so that I can specify my own delimiter?

  • F# compiler order of source files

    - by rwallace
    As I understand it, when using F#, you have to manually list the source files in dependency order for the compiler's benefit (if there is any way around that, please let me know!) Listing them on the command line from left to right obviously isn't going to scale. Is there a way to at least make it accept the list of files in a text file, one per line, preferably with the ability to put in blank lines and comments? I've checked the compiler options, and I don't see anything that looks promising.

  • Starting python debugger automatically on error

    - by jeremy
    This is a question I have wondered about for quite some time, yet I have never found a suitable solution. If I run a script and I come across, let's say an IndexError, python prints the line, location and quick description of the error and exits. Is it possible to automatically start pdb when an error is encountered? I am not against having an extra import statement at the top of the file, nor a few extra lines of code.
