  • In .NET MVC, is there an easy way to check if I'm on the home page?

    - by Hairgami_Master
    I need to take a particular action if a user logs in from the home page. In my LogOnModel, I have a hidden field: @Html.Hidden("returnUrl", Request.Url.AbsoluteUri) In my Controller, I need to check if that value is the Home page or not. In the example below, I'm checking to see if the user is on a particular page ("Account/ResetPassword"). Is there a way to check to see if they're on the home page without resorting to regular expressions? [HttpPost] public ActionResult LogOnInt(LogOnModel model) { if (model.returnUrl.Contains("/Account/ResetPassword")) { return Json(new { redirectToUrl = @Url.Action("Index","Home")}); } Any ideas? A million thanks!

  • Java splitting string by custom regex match

    - by slikz
    I am completely new to regular expressions so I'm looking for a bit of help here. I am compiling under JDK 1.5 Take this line as an example that I read from standard input: ab:Some string po:bubblegum What I would like to do is split by the two characters and colon. That is, once the line is split and put into a string array, these should be the terms: ab:Some string po:bubblegum I have this regex right now: String[] split = input.split("[..:]"); This splits at the semicolon; what I would like is for it to match two characters and a semicolon, but split at the space before that starts. Is this even possible? Here is the output from the string array: ab Some String po bubblegum I've read about Pattern.compile() as well. Is this something I should be considering?

  • Java or C# + XNA for some simple animations?

    - by lala
    I want to make a program that will involve some faces with various facial expressions. They will change from one facial expression to another based on their "mood" as influenced by user input. I know some java but I have done pretty much nothing with graphics. A friend tells me that it will be easier to do this in C# with XNA than to do it in java. I have about a month to do this, so I was hoping you folks would help me make a decision. Would I be better off figuring out how to do this in java, or learning C# and XNA and doing it in C#? Is it so much easier to do this in C# that it would be quicker to learn C# than to struggle with doing it in java? Will it probably come out looking much better if it is in C#?

  • How do I delete an object from an Entity Framework model without first loading it?

    - by Tomas Lycken
    I am quite sure I've seen the answer to this question somewhere, but as I couldn't find it with a couple of searches on SO or google, I ask it again anyway... In Entity Framework, the only way to delete a data object seems to be MyEntityModel ent = new MyEntityModel(); ent.DeleteObject(theObjectToDelete); ent.SaveChanges(); However, this approach requires the object to be loaded to, in this case, the Controller first, just to delete it. Is there a way to delete a business object referencing only for instance its ID? If there is a smarter way using Linq or Lambda expressions, that is fine too. The main objective, though, is to avoid loading data just to delete it.

  • Replace html tag with a certain class

    - by fire
    I am looking for suitable replacement code that allows me replace the content inside of any HTML tag that has a certain class e.g. $class = "blah"; $content = "new content"; $html = '<div class="blah">hello world</div>'; // code to replace, $html now looks like: // <div class="blah">new content</div> Bare in mind that: It wont necessarily be a div, it could be <h2 class="blah"> The class can have more than one class and still needs to be replaced e.g. <div class="foo blah green">hello world</div> I am thinking regular expressions should be able to do this, if not I am open to other suggestions such as using the DOM class (although I would rather avoid this if possible because it has to be PHP4 compatible).

  • Why is my regex so much slower compiled than interpreted ?

    - by miket2e
    I have a large and complex C# regex that runs OK when interpreted, but is a bit slow. I'm trying to speed this up by setting RegexOptions.Compiled, and this seems to take about 30 seconds for the first time and instantly after that. I'm trying to negate this by compiling the regex to an assembly first, so my app can be as fast as possible. My problem is when the compiling delay takes place: Regex myComplexRegex = new Regex(regexText, RegexOptions.Compiled); MatchCollection matches = myComplexRegex.Matches(searchText); foreach (Match match in matches) // <--- when the one-time long delay kicks in { } This is making compiling to an assembly basically useless, as I still get the delay on the first foreach call. What I want is for all the compiling delay to be done in advance when I compile to the assembly, not when the user runs the app. Where am I going wrong ? (The code I'm using to compile to an assembly is similar to http://www.dijksterhuis.org/regular-expressions-advanced/ , if that's relevant ).

  • Interesting or unique types encountered?

    - by user318904
    What is the most strange or unique type you have seen in a programming language? I was thinking the other day about a "random variable", ie whenever it is evaluated it yields a random value from some domain. It would require some runtime trickery. Also I bet there can be some interesting mapping of regular expressions into a type system. It does not necessarily have to be a built in or primitive type, but some random class that implements a domain specific type won't really be interesting just unique.

  • Run a site on Scheme

    - by Lajla
    I can't find this on Google (so maybe it doesn't exist), but I basically'd like to install something on a web server such that I can run a site on Scheme, PHP is starting to annoy me, I want to get rid off it, what I want is: Run Scheme sources towards UTF-8 output (duh) Support for SXML, SXLT et cetera, I plan to compose the damned thing in SXML and - to normal representation on at the end. Ability to read other files from the server, write them, set permissions et cetera Also some things to for instance determine the filesize of files, height of images, mime-types and all that mumbo-jumbo (optionally) connect to a database, but for what I want to do storing the entire database in S-expressions itself is feasible enough I don't need any fancy libraries and other things that come with it like CMS'es and what-not, except the support for SXML but I'm sure I can just find a lib for that anyway that I can load.

  • Pulling international street addresses / phone numbers from free-form text

    - by spitzanator
    Hey, folks. I'm looking for some regular expressions to help grab street addresses and phone numbers from free-form text (a la Gmail). Given some text: "John, I went to the store today, and it was awesome! Did you hear that they moved to 500 Green St.? ... Give me a call at +14252425424 when you get a chance." I'd like to be able to pull out: 500 Green St. (recognized as a street address) +14252425424 (recognized as a phone number) What makes this problem easier is that I don't care about parsing text that gets pulled out. That is, I don't care that Green is the name of the road or that 425 is the area code. I just want to grab strings that "look like" addresses or telephone numbers. Unfortunately, this needs to work internationally, as best as possible. Anyone have any leads? Thanks!

  • Eclipse: The icons in "Display View" are all greyed out

    - by Mark Silberbauer
    The discussion here describes the "display view" in eclipse which allows one to to quickly evaluate java expressions. The thing is, when I open the display view the icons remain greyed out and I can't execute anything. The only icon that isn't is "clear console". The odd thing is, alot of the screenshots on the web show the same behaviour but the people posting about the feature don't mentioned it. There aren't any options in the context sensitive menu either. I'm trying it on a java project. I've tried it in the debug view and I get the same issue. I'll provide a screenshot once my hosting is sorted. I'm using eclipse 3.4.

    - by Ph.E
    Greetings friends, I am developing a web application that will allow the customer to enter a personalized message, which will then be converted to HTML. Well, the problem is that I can not allow the insertion of Javascript code. So I need a method that filters the text, searching for and remove it. I think the regular expressions to solve my problem, but I'm having difficulty building. Some of his friends could help me, or has already developed something for this. Thank you.

  • Image equivalent of ActionLink in ASP.NET MVC

    - by Jason Whitehorn
    In ASP.NET MVC is there an equivalent of the Html.ActionLink helper for Img tags? I have a controller action that outputs a dynamically generated JPEG and I wanted to use the same Lambda expressions to link to it as I do HREFs using ActionLink. Alternatively, a helper that just gives the URL to a route (again specified using Lambdas) would also be acceptable. EDIT: I had originally specified that I was using Preview 5, however I see that a Beta has been released. So all-in-all the version number was an unneeded piece of info as I may be upgrading soon :-)

  • Replace String pattern in Java

    - by Hirantha
    I have the following string "value=\"\\d{4}((((0[1-9])|(1[0-2]))((0[1-9])|([12]\\d)|(3[01]))?)?|(\\-(((0[1-9])|(1[0-2]))(\\-((0[1-9])|([12]\\d)|(3[01])))?)?)?)d{4}" There I want to replace all the occurrences of "{" with NCHAR(0x7B) "}" with NCHAR(0x7D). An the content in-between "{ }" should remain unchanged: Ex: \\d{4} after replacing -> NCHAR(0x7B) 4 NCHAR(0x7D). Is there a way to do this using Regular Expressions in Java?. Anyway, this can be done processing the whole string using string operations.

  • Proper chart scaling in Reporting Services 2005

    - by lastas
    I'm developing a simple bar-chart in Reporting Services 2005 with a stored procedure as data-source. The values in this graph can be both positive and negative, and can span a very big range, and hence I cannot specify any non-dynamic scale that will work for all scenarios. The problem I'm facing is that the automatic scaling pretty much sucks. I get no line to show where the zero-point is, and the y-scale labels are from top to bottom: 8818 -191181 -391181 etc etc... So my question is, what is the best approach to make the scale more adapted to human reading? Is there any guide out there? Does reporting services 2008 handle this better? Also, moving away from Reporting Services is not really an option. I realize how to put values and expression in the max, min, and the gridline interval fields, although its more of a question what expressions I should put there.

  • Yet another URL prefix regex question (to be used in C#).

    - by Hamish Grubijan
    Hi, I have seen many regular expressions for Url validation. In my case I want the Url to be simpler, so the regex should be tighter: Valid Url prefixes look like: http[s]://[www.]addressOrIp[.something]/PageName.aspx[?] This describe a prefix. I will be appending ?x=a&y=b&z=c later. I just want to check if the web page is live before accessing it, but even before that I want to make sure that it is properly configured. I want to treat bad url and host is down conditions differently, although when in doubt, I'd rather give a host is down message, because that is an ultimate test anyway. Hopefully that makes sense. I guess what I am trying to say - the regex does not need be too aggressive, I just want it to cover say 95% of the cases. This is C# - centric, so Perl regex extensions are not helpful to me; let's stick to the lowest common denominator. Thanks!

  • Searching for URL's Relative to Site Root in Javascript Source

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

  • iPhone / ios development - best way to check if password is secure enough?

    - by Pranoy C
    what is the best way to check the strength of a password in iOS development? I came across this post: What is the best way to check the strength of a password? but this is not iOS specific. My question is - Does Apple or third party libraries provide any libraries by default which I can use to check if the user entered a secure password? If not, then as the above post says, is using regular expressions the best way? Does Apple have any requirements which our app needs to implement to make sure user has a secure password? I am planning on using the keychain to store the password.

  • Apply a class to a <h1> based on the site url

    - by user1870639
    I'm new to PHP and want to apply a specific class to the title of my page depending on what part of the site the viewer is browsing. For instance, I want to apply the class "blog" to the if the viewer is at domain.com/blog OR domain.com/blog/post-1 so on and so forth BUT apply the class "pics" if they're viewing domain.com/pics or domain.com/pics/gallery-1 etc etc. I found something that could be modified to serve my needs using javascript here but I figured seeing as I'm using PHP already, it'd make more sense to keep this sort of thing server side. As I say, I'm new to PHP. I've experimented with some regular expressions, but to no avail.

  • How to move many files in multiple different directories (on Linux)

    - by user1335982
    My problem is that I have too many files in single directory. I cannot "ls" the directory, cos is too large. I need to move all files in better directory structure. I'm using the last 3 digits from ID as folders in reverse way. For example ID 2018972 will gotta go in /2/7/9/img_2018972.jpg. I've created the directories, but now I need help with bash script. I know the IDs, there are in range 1,300,000 - 2,000,000. But I can't handle regular expressions. I wan't to move all files like this: /images/folder/img_2018972.jpg -> /images/2/7/9/img_2018972.jpg I will appreciate any help on this subject. Thanks!

  • Need Regex for to match special situations

    - by Daniel
    I'm desperately searching for regular expressions that match these scenarios: 1) Match alternating chars I've a string like "This is my foobababababaf string" - and I want to match "babababa" Only thing I know is the length of the fragment to search - I don't know what chars/digits that might be - but they are alternating. I've really no clue where to start :( 2) Match combined groups In a string like "This is my foobaafoobaaaooo string" - and I want to match "aaaooo". Like in 1) I don't know what chars/digits that might be. I only know that they will appear in two groups. I experimented using (.)\1\1\1(.)\1\1\1 and things like this...

  • Only strip commas surrounded by numbers in a string

    - by overlook77
    I am using StreamReader to read each line of a CSV file into a string. As I am processing each line, I need to strip out any commas that ONLY are surrounded by other numbers. For example, if the string was: "textfield1", "textfield2", "100.00", "1,070.00" I would need to only take the comma out of "1,070.00" from this entire string, resulting in: "textfield1", "textfield2", "100.00", "1070.00" Each string read from the CSV file can differ in number of fields, length, etc., so I need to use something (Regular Expressions maybe?) that looks at the entire string without hardcoding a location or blanket removal of all commas. Here is the approach I have been trying: StreamReader sr = new StreamReader(strInputFile); string nextLine = sr.ReadLine(); try { while ((nextLine = sr.ReadLine()) != null) { string rawtext = nextLine.Replace("[0-9]"+","+"[0-9]" , "[0-9]"+"[0-9]"); // ....rest of code } } This obviously doesn't work because I don't understand how to do this :) I am new at C# and inexperienced in Regex, so hopefully this is relatively simple.

  • Casting in mixed type calculations in C?

    - by yCalleecharan
    Hi, If I define these variables: double x0, xn, h; int n; and I have this mathematical expression: h = (xn - x0)/n; Is it necessary that I cast n into double prior doing the division for maximum accuracy like in h = (xn - x0)/ (double) n; I wrote a program to check the above but both expressions give the same answers. I understand that C will promote the integer to double type as variables xn and x0 are of type double but strangely enough in a book, the second expression with casting was emphasized. Thanks a lot...

  • antlr: How to rewrite only specific

    - by user1293945
    I am sure antlr can solve my problem, but can't figure out how to implement it, even high level. I rapidly got caught into syntax problems of antlr itself. My grammar is quite simple and made of following tokens and rules. Don't really need to go in their details here. The evaluator resolves to expressions, which finally resolve to IDENT: evaluator : expression EOF! ; ... ... term : PARTICIPANT_TYPE(IDENT | '('! expression ')'! | max | min | if_ | NUMBER)+ ; Now, I would like to analyse and rewrite the 'term', so that IDENT tokens (and them only) get re-written with the PARTICIPANT_TYPE. All the others should simply remain the same.

  • Exclude subexpression from regex in c++

    - by wyatt
    Suppose I was trying to match the following expression using regex.h in C++, and trying to obtain the subexpressions contained: /^((1|2)|3) (1|2)$/ Suppose it were matched against the string "3 1", the subexpressions would be: "3 1" "3" "1" If, instead it were matched against the string "2 1", the subexpressions would be: "2 1" "2" "2" "1" Which means that, depending on how the first subexpression evaluates, the final one is in a different element in the pmatch array. I realise this particular example is trivial, as I could remove one of the sets of brackets, or grab the last element of the array, but it becomes problematic in more complicated expressions. Suppose all I want are the top-level subexpressions, the ones which aren't subexpressions of other subexpressions. Is there any way to only get them? Or, alternatively, to know how many subexpressions are matched within a subexpression, so that I can traverse the array irrespective of how it evaluates? Thanks
