  • Can you detect a 301 redirect with Microsoft.XMLHTTP object?

    - by dmb
    I'm using VBScript and the Microsoft.XMLHTTP object to scrape some web data. I have a list of URLs to check, but unfortunately some of them 301 redirect to others on the list, so I wind up with redundant data. Is it at all possible to make the XMLHTTP object fail on 301 redirect? Or at least cache the original response header? Or otherwise just let me know what happened? (notes: I have no control over the server I'm requesting data from; when I get new data, I could check if it's redundant, but I'd like to avoid that if possible). Any ideas would be greatly appreciated.

  • Overriding unique indexed values

    - by Yeti
    This is what I'm doing right now (name is UNIQUE): SELECT * FROM fruits WHERE name='apple'; Check if the query returned any result. If yes, don't do anything. If no, a new value has to be inserted: INSERT INTO fruits (name) VALUES ('apple'); Instead of the above is it ok to insert the value into the table without checking if it already exists? If the name already exists in the table, an error will be thrown and if it doesn't, a new record will be inserted. Right now I am having to insert 500 records in a for loop, which results in 1000 queries. Will it be ok to skip the "already-exists" check?

  • How to compute a unicode string which bidirectional representation is specified?

    - by valdo
    Hello, fellows. I have a rather pervert question. Please forgive me :) There's an official algorithm that describes how bidirectional unicode text should be presented. http://www.unicode.org/reports/tr9/tr9-15.html I receive a string (from some 3rd-party source), which contains latin/hebrew characters, as well as digits, white-spaces, punctuation symbols and etc. The problem is that the string that I receive is already in the representation form. I.e. - the sequence of characters that I receive should just be presented from left to right. Now, my goal is to find the unicode string which representation is exactly the same. Means - I need to pass that string to another entity; it would then render this string according to the official algorithm, and the result should be the same. Assuming the following: The default text direction (of the rendering entity) is RTL. I don't want to inject "special unicode characters" that explicitly override the text direction (such as RLO, RLE, etc.) I suspect there may exist several solutions. If so - I'd like to preserve the RTL-looking of the string as much as possible. The string usually consists of hebrew words mostly. I'd like to preserve the correct order of those words, and characters inside those words. Whereas other character sequences may (and should) be transposed. One naive way to solve this is just to swap the whole string (this takes care of the hebrew words), and then swap inside it sequences of non-hebrew characters. This however doesn't always produce correct results, because actual rules of representation are rather complex. The only comprehensive algorithm that I see so far is brute-force check. The string can be divided into sequences of same-class characters. Those sequences may be joined in random order, plus any of them may be reversed. I can check all those combinations to obtain the correct result. Plus this technique may be optimized. For instance the order of hebrew words is known, so we only have to check different combinations of their "joining" sequences. Any better ideas? If you have an idea, not necessarily the whole solution - it's ok. I'll appreciate any idea. Thanks in advance.

  • How do I solve "405 Method Not Allowed" for our subversion setup?

    - by macke
    We're serving our source code using VisualSVN running on Windows Server 2003. Recently, we split a portion of a project into a new project in it's own repository, and then linked it back to the original project using svn:externals. Since then, we've been having issues when we try to commit files with Subclipse. The error we're getting is: svn: Commit failed (details follow): svn: PROPFIND of '/svn': 405 Method Not Allowed (https://svn.ourserver.com) Googling for a while didn't really help, our config seems to be correct. It should also be noted that we've been running this server for a while no without these problems and apart from splitting the project into two repositories, no changes have been made to the server (ie, config files are the same). It should also be noted that these errors only appear when we try to check in multiple files at once. If we check in one file at a time there are no errors. Also, it only appears in Subclipse as far as we know right now, Versions.app (OS X) seems to work fine so that is our current workaround. So, the questions is how do I analyze the error to find the cause and subsequently fix it? I'm by no means a svn guru and right now I'm clueless. EDIT: It seems we can check in multiple files in the same package, but not files from multiple packages. Also, when I "split" the project into two repositories, I imported the original repository with a new name. I did not do a dump and then import that dump. Could that be the source of our issues, and if so, how would I solve that? EDIT: After some jerking around it seems as though it is indeed related to when checking in files in different repositories. If I try to do a single commit in both Repo A and Repo B (referenced by svn:externals) at the same time, I get the error. Versions.app handles this correctly, but I guess it might just be doing two commits, not a single one. Subclipse fails miserably. For now, we simply do multiple commits, one for Repo A and one for Repo B, that works just fine. If anyone smarter than me could fill in the details why this is happening, whether or not this kind of setup is stupid etc, please go right ahead.

  • xVal ignoring fields that are hidden

    - by gmcalab
    I have a form where a user can toggle receiving funds either via check or via electronic transfer. When they choose either way in a list box, the respective part of the form hides. If they choose electronic transfer only bank info fields show, if they choose via check only address info shows and the bank fields are hidden. Well, since they choose one way or another I want to, not validate for something that is hidden. (Client Side) Is there a way to set xVal to only validate fields that are not visible? I tried to override validate with the following but no dice... $('#EditPayment').validate({ elementwhichishidden: { required: function(element) { return ($(element).parent().parent().css('display') != 'none'); } } });

  • JSTree select_node event and checkbox

    - by Ted Mosbey
    Hi there! I have a jstree in which I used the select_node event to toggle nodes(expand), and have therefore removed the toggle arrows in the tree since they look ugly and I've no need for them. Now I've added the checkbox plugin to use within the tree, but have found the select_node event is disabled when the plugin is active. How would I toggle my nodes with the checkbox plugin active, without re-adding the ugly toggle arrows? I could do it in the check/uncheck event, but I don't want to check/uncheck everytime I expand a node.

  • Show image from url in uiimageview

    - by skiria
    I try to show a image in my iphone app but it doesn't show. I connect in IB and I check to show a local image, it workd good. I also check the url from image and it is ok. I use the next code: NSURL *imageURL = [NSURL URLWithString: aVideo.urlThumbnail]; NSData *imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage *image = [UIImage imageWithData:imageData]; imageView.image = image; and //Video.h NSString *urlThumbnail; and this is my code on the view. - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [tableView reloadData]; } - (void)viewDidLoad { [super viewDidLoad]; NSURL *imageURL = [NSURL URLWithString: aVideo.urlThumbnail]; NSData *imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage *image = [UIImage imageWithData:imageData]; imageView.image = image; }

  • Changing background images like this

    - by Azzyh
    If you guys check out this webpage: http://www2.scandvision.se/oresund10/ How have they done this background fade in fade out? When i check the source this <img id="wrapper-background" src="images/body-background-0.jpg" alt="Background" /> and i think theres some kind of script maybe php or js, or both, that every 5 sec changes the background: images/body-background-1.jpg images/body-background-2.jpg images/body-background-3.jpg and so on.. So how did they do this? an example would be great, as i want to learn how to do that. If i was going to do something like this i think i would only manage to do a script in php that randomize everytime you refresh. Thank you, this will expand my knowledge

  • BigInteger.Parse() on hexadecimal number gives negative numbers.

    - by brickner
    I've started using .NET 4 System.Numerics.BigInteger Structure and I've encountered a problem. I'm trying to parse a string that contains a hexadecimal number with no sign (positive). I'm getting a negative number. For example, I do the following two asserts: Assert.IsTrue(System.Int64.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "Int64"); Assert.IsTrue(System.Numerics.BigInteger.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "BigInteger"); The first assert succeeds, the second assert fails. I actually get -8 instead of 8 in the BigInteger. The problem seems to be when I'm the hexadecimal starts with 1 bit and not 0 bit (a digit between 8 and F inclusive). If I add a leading 0, everything works perfectly. Is that a bad usage on my part? Is it a bug in BigInteger?

  • How to wrap Plone authentication around a third-party servlet?

    - by smocking
    We're using Plone to serve up some third-party middle-ware. Unfortunately the middle-ware has a particular servlet that gets invoked from a Java applet and doesn't do any kind of authentication. I would like to firewall this off and somehow wrap authentication around it, preferably using the existing session that users will have on Plone. My first idea was to configure nginx (which we're using as the reverse proxy) to check the cookie and only proxy if the user has a valid session (along the lines of this example). However, how to check the session ID against Plone, since it's all stored in the Zope database? Alternatively we could have a Plone python script that basically passes everything along to the back-end after authenticating, but I'm not sure how to do that. Any suggestions? Or alternative ideas?

  • Searching for empty methods

    - by Brian McCord
    I am currently working on a security audit/code review of our system. This requires me to check all pages in the system and make sure that the code behind contains two methods that are used to check security. Sometimes the code in these methods get commented out to make testing easier. So, my question is does anyone know an easy way to search code, make sure the methods are present, and to determine which ones have no code or have all the code commented out. It would make my job much easier if I can get a list instead of having to look at every file... I'm sure I could write this myself, but I thought someone may know of something that already exists. Thanks!

  • Make a Method of the Business Layer secure. best practice / best pattern [.net/c#]

    - by gsharp
    Hi We are using ASP.NET with a lot of AJAX "Page Method" calls. The WebServices defined in the Page invokes methods from our BusinessLayer. To prevent hackers to call the Page Methods, we want to implement some security in the BusinessLayer. We are struggling with two different issues. First one: public List<Employees> GetAllEmployees() { // do stuff } This Method should be called by Authorized Users with the Role "HR". Second one: public Order GetMyOrder(int orderId) { // do sutff } This Method should only be called by the owner of the Order. I know it's easy to implement the security for each method like: public List<Employees> GetAllEmployees() { // check if the user is in Role HR } or public Order GetMyOrder(int orderId) { // check if the order.Owner = user } What I'm looking for is some pattern/best practice to implement this kind of security in a generic way (without coding the the if then else every time) I hope you get what i mean :-) Thanks for you help.

  • How do you replace many characters in a regex?

    - by macca1
    I am sanitizing an input field and manually getting and setting the caret position in the process. With some abstraction, here's the basic idea: <input type="text" onkeyup"check(this)"> And javascript... function check(element) { var charPosition = getCaretPosition(element); $(element).val( sanitize( $(element).val() ) ); setCaretPosition(element, charPosition); } function sanitize(s) { return s.replace(/[^a-zA-Z0-9\s]/g, ''); } This is working fine except when a character does actually get sanitized, my caret position is off by one. Basically I'd like a way to see if the sanitize function has actually replaced a character (and at what index) so then I can adjust the charPosition if necessary. Any ideas?

  • Good link checking tool?

    - by AP257
    Hi all Can anyone recommend a good, free link checker to check all pages within a domain? Ideally a browser add-on or a web app (otherwise something that runs on OSX). Crucially it needs to follow links recursively within a domain. Links outside the domain should be followed to a depth of 1, but not checked recursively. This is for the fairly common situation where you want to check all pages on your own site, but not evaluate the links on e.g. Google's homepage. I can't find anything suitable. Am I missing something? I've tried the Firefox LinkChecker add-on and the W3C link validator - neither seem to have the 'follow recursively within a domain' property, or am I being dumb? I know Xenu does this, but I don't run Windows.

  • Hibernate object equality checking

    - by Sujee
    As far as I understand(correct me if I am wrong) Hibernate uses object reference to check the object equality. When Hibernate identifies that there are more than one objects attached to same DB record, it throws following exception. "a different object with the same identifier value was already associated with the session" My question is, does Hibernate use equal() method to check the object equality (The default equal method uses object reference)? If it is true, will overridden equal() method change the Hibernate behavior? Note: My question is not about the issues of implementing equal() or hashCode() methods in a Hibernate persisted object. Thank you.

  • Getting the errors for code in unopened .aspx pages

    - by Glennular
    Is there a way to check for errors in unopened *.ASPX pages. For example, if you change the name of a function Visual Studio will catch the error on the page and list it in the "Error List" only if the page is opened and being validated? I guess the question could be is there a validation option opposed to the compile option to check for errors? (Yes, i know code should go into the pre-compiled code-behind pages.) How do i find out about the following without running the page through the webserver or opening the page to be validated in VS? <script runat="server"> Public Sub MyFunciton() Undefined_FUNCTION() End Sub </script>
