  • Using PHP, how to parse the title and meta tags from a HTML page?

    - by Dylan Taylor
    Hey guys, I need to be able to get the TITLE and DESCIPTION metadata out of a page. I've been trying to do this but I've been getting more errors than actual results. (I have an array of about 10 URLS, usually only about 2 of them give me the descrption. I have yet to get the title). So how do I, in PHP, get the Desc and Title from a remote page, and if there is none or if there's an error, ignore it? -Dylan

  • Delphi : Sorted List

    - by Sethu
    I need to sort close to a 1,00,000 floating point entries in delphi. I am new to delphi and would like to know if there are any readymade solutions available. I tried a few language provided constructs and they take an inordinate amount of time to run to completion.(a 5-10 sec execution time is fine for the application)

  • How to include only BOOST smart pointer codes into a project?

    - by afriza
    What are best practices to include boost smart pointer library only without adding all boost libraries into the project? I only want boost smart pointer library in my project and I don't want to check in/commit 200 MB source codes (boost 1.42.0) into my project repository just for that. What more, my windows mobile project itself doesn't even reach 10% of that size!

  • Time Saving Minutiae

    - by Dave Jarvis
    What little tricks do you use to save time when developing? For example: In JDeveloper, change the default editor to Source view from Design view for JSP files.   Tools » Preferences » File Types » Default Editors » JSP Tag File By default, JDeveloper opens JSP files in Design view, which can take 10 to 15 seconds to begin editing a file. Opening files in Source view only takes 2 seconds.

  • Grayscale in matlab

    - by ruthenium
    I'm trying to convert a 2D array to grayscale but using mat2gray doesn't do anything and imshow() appears to create a binary image that when I graph I cannot rotate it, e.g. the original array is 2d but maps in 3d. So, what is the best way to take a grayscale of 2d array in Matlab so if you have A=rand(5,10) or something and want to take a grayscale of that, what is the best way?

  • Parallel processing in R 2.11 Windows 64-bit using SNOW not quite working

    - by Abhijit
    I'm running R 2.11 64-bit on a WinXP64 machine with 8 processors. With R 2.10.1 the following code spawned 6 R processes for parallel processing: require(foreach) require(doSNOW) cl = makeCluster(6, type='SOCK') registerDoSNOW(cl) bl2 = foreach(i=icount(length(unqmrno))) %dopar% { (Some code here) } stopCluster(cl) When I run the same code in R 2.11 Win64, the 6 R processes are not spawning, and the code hangs. I'm wondering if this is a problem with the port of SNOW to 2.11-64bit, or if any additional code is required on my part. Thanks

  • Are "EXC_BREAKPOINT (SIGTRAP)" exceptions caused by debugging breakpoints?

    - by Dennis
    I have a multithreaded app that is very stable on all my test machines and seems to be stable for almost every one of my users (based on no complaints of crashes). The app crashes frequently for one user, though, who was kind enough to send crash reports. All the crash reports (~10 consecutive reports) look essentially identical: Date/Time: 2010-04-06 11:44:56.106 -0700 OS Version: Mac OS X 10.6.3 (10D573) Report Version: 6 Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000002, 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 com.apple.CoreFoundation 0x90ab98d4 __CFBasicHashRehash + 3348 1 com.apple.CoreFoundation 0x90adf610 CFBasicHashRemoveValue + 1264 2 com.apple.CoreText 0x94e0069c TCFMutableSet::Intersect(__CFSet const*) const + 126 3 com.apple.CoreText 0x94dfe465 TDescriptorSource::CopyMandatoryMatchableRequest(__CFDictionary const*, __CFSet const*) + 115 4 com.apple.CoreText 0x94dfdda6 TDescriptorSource::CopyDescriptorsForRequest(__CFDictionary const*, __CFSet const*, long (*)(void const*, void const*, void*), void*, unsigned long) const + 40 5 com.apple.CoreText 0x94e00377 TDescriptor::CreateMatchingDescriptors(__CFSet const*, unsigned long) const + 135 6 com.apple.AppKit 0x961f5952 __NSFontFactoryWithName + 904 7 com.apple.AppKit 0x961f54f0 +[NSFont fontWithName:size:] + 39 (....more text follows) First, I spent a long time investigating [NSFont fontWithName:size:]. I figured that maybe the user's fonts were screwed up somehow, so that [NSFont fontWithName:size:] was requesting something non-existent and failing for that reason. I added a bunch of code using [[NSFontManager sharedFontManager] availableFontNamesWithTraits:NSItalicFontMask] to check for font availability in advance. Sadly, these changes didn't fix the problem. I've now noticed that I forgot to remove some debugging breakpoints, including _NSLockError, [NSException raise], and objc_exception_throw. However, the app was definitely built using "Release" as the active build configuration. I assume that using the "Release" configuration prevents setting of any breakpoints--but then again I am not sure exactly how breakpoints work or whether the program needs to be run from within gdb for breakpoints to have any effect. My questions are: could my having left the breakpoints set be the cause of the crashes observed by the user? If so, why would the breakpoints cause a problem only for this one user? If not, has anybody else had similar problems with [NSFont fontWithName:size:]? I will probably just try removing the breakpoints and sending back to the user, but I'm not sure how much currency I have left with that user. And I'd like to understand more generally whether leaving the breakpoints set could possibly cause a problem (when the app is built using "Release" configuration).

  • Why would some POST data go missing when using Uploadify?

    - by Chad Johnson
    I have been using Uploadify in my PHP application for the last couple months, and I've been trying to track down an elusive bug. I receive emails when fatal errors occur, and they provide me a good amount of details. I've received dozens of them. I have not, however, been able to reproduce the problem myself. Some users (like myself) experience no problem, while others do. Before I give details of the problem, here is the flow. User visits edit screen for a page in the CMS I am using. Record id for the page is put into a form as a hidden value. User clicks the Uploadify browse button and selects a file (only single file selection is allowed). User clicks Submit button for my form. jQuery intercepts the form submit action, triggers Uploadify to start uploading, and returns false for the submit action (manually cancelling the form submit event so that Uploadify can take over). Uploadify uploads to a custom process script. Uploadify finishes uploading and triggers the Javascript completion callback. The Javascript callback calls $('#myForm').submit() to submit the form. Now that's what SHOULD happen. I've received reports of the upload freezing at 100% and also others where "I/O Error" is displayed. What's happening is, the form is submitting with the completion callback, but some post parameters present in the form are simply not in the post data. The id for the page, which earlier I said is added to the form as a hidden field, is simply not there in the post data ($_POST)--there is no item for 'id' in the $_POST array. The strange thing is, the post data DOES contain values for some fields. For instance, I have an input of type text called "name" which is for the record name, and it does show up in the post data. Here is what I've gathered: This has been happening on Mac OSX 10.5 and 10.6, Windows XP, and Windows 7. I can post exact user agent strings if that helps. Users must use Flash 10.0.12 or later. We've made it so the form reverts to using a normal "file" field if they have < 10.0.12. Does anyone have ANY ideas at all what the cause of this could be?

  • What Date Format Should I Send When Using Oracle.DataAcess.

    - by discwiz
    Converting from usind Micorsofts Syste.Data.OracleClient to what I believe is called Oracles ODT (Oracle.DataAccess 10.2.0.100). When I try and send a date I get this error "ORA-1858: a non-numeric character was found where a numeric was expected". This code worked great using System.Data.OracleClient. cmd.Parameters.Add(New OracleParameter("I_FIRST_LOSS_EVENT_DATE", OracleDbType.Date)).Value = .LossEventsMessages(0).LossEventTime Thanks, Dave

  • Help with a logic problem

    - by Stradigos
    I'm having a great deal of difficulty trying to figure out the logic behind this problem. I have developed everything else, but I really could use some help, any sort of help, on the part I'm stuck on. Back story: *A group of actors waits in a circle. They "count off" by various amounts. The last few to audition are thought to have the best chance of getting the parts and becoming stars. Instead of actors having names, they are identified by numbers. The "Audition Order" in the table tells, reading left-to-right, the "names" of the actors who will be auditioned in the order they will perform.* Sample output: etc, all the way up to 10. What I have so far: using System; using System.Collections; using System.Text; namespace The_Last_Survivor { class Program { static void Main(string[] args) { //Declare Variables int NumOfActors = 0; System.DateTime dt = System.DateTime.Now; int interval = 3; ArrayList Ring = new ArrayList(10); //Header Console.Out.WriteLine("Actors\tNumber\tOrder"); //Add Actors for (int x = 1; x < 11; x++) { NumOfActors++; Ring.Insert((x - 1), new Actor(x)); foreach (Actor i in Ring) { Console.Out.WriteLine("{0}\t{1}\t{2}", NumOfActors, i, i.Order(interval, x)); } Console.Out.WriteLine("\n"); } Console.In.Read(); } public class Actor { //Variables protected int Number; //Constructor public Actor(int num) { Number = num; } //Order in circle public string Order(int inter, int num) { //Variable string result = ""; ArrayList myArray = new ArrayList(num); //Filling Array for (int i = 0; i < num; i++) myArray.Add(i + 1); //Formula foreach (int element in myArray) { if (element == inter) { result += String.Format(" {0}", element); myArray.RemoveAt(element); } } return result; } //String override public override string ToString() { return String.Format("{0}", Number); } } } } The part I'm stuck on is getting some math going that does this: Can anyone offer some guidance and/or sample code?

  • Multidimensional Array with different types in java

    I want to store a data structure thats a table with one column Strings and another column of Ints. List<Entry<String, Integer>> li = new LinkedList<Entry<String, Integer>>(); would do the job for a list but I would rather have the performance of an array. I tried Entry<String, Integer>[] = new Entry<String, Integer>[10]; but that doesn't seem to work.
