  • How do I write a regex that ignores strings starting with a particular prefix, and captures everythi

    - by Mark Rogers
    Background: I'm trying to come up with a regex for a rewrite rule that will take anything that does not start with a particular prefix, and add that prefix to it. But urls that already have the prefix should be rejected by the regular expression (because they already have the url). Example: If the prefix is s1 a string like home will capture the home part. But a string like s1/home, will not capture anything. This way I can add the capture group onto the prefix, so that 'home' will become 's1/home'. I've tried (^s1/), but I'm missing something here, because that rejected 'home' for some reason.

  • ASP MVC html helpers in partial views

    - by Rabbi
    I am still trying to figure out how to create reusable partial views in MVC Lets say I would like to create a partial view to display a form for submitting an address. Then in my ViewModel I have two addresses (Home address & Work Address) So I would think that in my view I call HTML.Partial for each one like this @Html.Partial("Address", Model.HomeAddress) @Html.Partial("Address", Model.WorkAddress) but what happens is instead of the fields having names like HomeAddress.Street, HomeAddress.City etc. they just have the regular field names Street, City, etc. so the binder on the HTTPPost action has no idea what to do with them Thanks in advance

  • How to represent datetime of different time zomes in C#

    - by Mohoch
    I have a .NET WebService (written in C#), that is supposed to serve people around the world. With each request I get the user's datetime in his own time zone with the format : yyyy/MM/dd HH:mm ZZZZ. I have to convert the string to something representing the original date and time and specifying the time zone in GMT. I have to make some logical calculations and keep it in the database. The regular DateTime doe's not support this. it does not have a property specifying the time zone. When I try to convert my string into DateTime - it simply converts it to my local time. I do not want to keep my time in UTC, because I have some logic that has to run per user by his own time. Does anyone know a C# class that handles this?

  • eclipse + multiple checkouts of version-controlled projects

    - by Jason S
    We're using eclipse and svn. We keep the .project file in version control. The problem is, if you have more than one checked-out project (e.g. a trunk checkout and a feature branch) and would like them both to be available in Eclipse, you lose, because the .project files are identical and therefore can't both be imported into Eclipse. What's the right way to deal with this? (I'm mostly having to deal with this in TI's Code Composer v4 which uses an older version of eclipse, but I'm also going to need to do this in the regular Eclipse)

  • Tune cindent "switch" indentation

    - by Don Reba
    Nemerle is a C-like language and mostly works very well with cindent. However, its construct analogous to switch is called match: match (x) { | "Hello World" => ... | _ => ... } Is it possible to get the cinoptions for switch statements to apply to this construct, instead? Maybe there is a regular expression I can set somewhere. If not, can I get the vertical bars to align with the braces another way?

  • How do you install cocos2d-iphone on the Mac?

    - by johnfromberkeley
    There are no good instructions for installing cocos2d for iPhone on the mac. I downloaded the current build from git, a folder called "cocos2d-iphone-0.99.1". i put this folder in /Developer/Libary. Q: is this right? I tried running the file called "install_template.sh". it said the templates were already installed. Instead, I manually dragged the templates folders where they belong, and they ~do~ appear in the XCode's "New Project" dialog. When I create a new cocos2d project, I see all these red links for project files, instead of the regular black links. When I try to open them in the finder, nothing happens. I can tell that something is not linked. Can someone please help walk me through this? Thanks!

  • Ruby: map tags into a boolean condition to get a true/false result

    - by cgyDeveloper
    I have an array of tags per item like so: item1 = ['new', 'expensive'] item2 = ['expensive', 'lame'] I also have a boolean expression as a string based on possible tags: buy_it = "(new || expensive) && !lame" How can I determine if an item matches the buying criteria based on the tags associated with it? My original thought was to do a gsub on all words in buy_it to become 'true' or 'false' based on them existing in the itemx tags array and then exec the resulting string to get a boolean result. But since the Ruby community is usually more creative than me, is there a better solution?

  • 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.

  • Is allocating a dynamic array without specifying size well formed code?

    - by Als
    The following simple program snippet gives compilation errorswith gcc-4.3.4. Program: int main() { char *ptr = new char[10]; char *ptr1 = new char[]; return 0; } Compilation errors: prog.cpp: In function ‘int main()’: prog.cpp:4: error: expected primary-expression before ‘]’ token prog.cpp:3: warning: unused variable ‘ptr’ prog.cpp:4: warning: unused variable ‘ptr1’ But the same compiles cleanly with MSVC without any diagnostic message. So my question is: Does the Standard allow an new [] to be called without specifying the size? Or this a bug in MSVC? Can someone provide a reference from the standard which will conclusively say that the above code example is ill-formed or well-formed? I have had a look at: 5.3.4 New [expr.new] & 18.4.1.2 Array forms [lib.new.delete.array] but couldnt find any conclusive evidence about the behavior.

  • Is possible to set generic type by another class?

    - by Soul_Master
    I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code? Thanks,

  • How do I rewrite a request by hostname unless it is a specified value?

    - by Tim
    My app will have a regular domain - let's say example.com - which will have information about logging in, signing up, etc. It will also host numerous other domains dynamically. My app serves the webpage for these at http://example.com/site/foobar.com/ So, I need to redirect all requests where the hostname is not example.com to /site/[hostname]/ I'm writing this in Django and hosting with Apache. How do I set up a rewrite rule to do this? The user must not know they are on any other site but foobar.com and if the user browses to foobar.com/something - the URL must be rewritten to /site/foobar.com/something

  • JQUERY: Multiplying input elements select box and radio boxes and hidden inputs

    - by Andrew Tan
    Evening, I'm tyring to multiply different input elements but for some reason it's giving me a NAND error. As the user selects, check or modify the values of any element. This should change the total amount. http://jsfiddle.net/aQ5K8/ <select name="select"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> </select> <input name="radio" type="radio" id="radio" value="10" tvalue="100" /> <input name="radio" type="radio" id="radio" value="20" tvalue="200" /> <label id="Total"></label> Also if you take a look at the jsfiddle code i have tvalue=100 and the other is =200 as a custom attributes, how would I access that instead of accessing the regular html value. Thank you.

  • Get name and value from the input tag

    - by DroidIn.net
    Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

  • Bind web user control property in markup

    - by Ian Levy
    I'm sure it's elementary but I can't figure it out. This does not work - the the binding expression is passed as string to the control: {<uc:usercontrol runtat="server" message='<%#Me.protectedVariable%>'/>} The code behind include a Page.Databind() call in page_load. But this does work: <uc:usercontrol runat="server" id="usercontrol1"/> And in code behind page_load: usercontrol1.message = Me.protectedVariable Do I have to bind from the code-behind? Is this a page life cycle issue?

  • How to setup a development Active Directory

    - by Rob
    Does anyone have any suggestions on how to setup a development environment for active directory? We are thinking of using development.contoso.com or something along those lines that is a completely separate envnironment from our production. This will be used for things like Dev SharePoint and possibly a Dev exchange server. Maybe even a dev CRM. We are thinking of setting this up all using virtual machines. Possibly having the production get replicated down on a regular basis as well. Does anyone have an experience with this or any suggestions on what to do or not to do for this?

  • Validation controls error message from Resource file and parameterized

    - by BigBoss
    Hi, I would like to get validation messages for validation controls from resource files. I know I can do that easily by following code snippet. <%$ Resources:[filename prefix,]resource-key %> or <asp:Label ID="Label1" runat="server" meta:resourcekey="resource-key-prefix" /> But I would also like to parameterized it. e.g. Above Resource Expression will give me message like "Fill Information.". What I have in resource file is "Fill {0} Information." which should show end user message like "Fill Address Information.".

  • Are spinlocks a good choice for a memory allocator?

    - by dsimcha
    I've suggested to the maintainers of the D programming language runtime a few times that the memory allocator/garbage collector should use spinlocks instead of regular OS critical sections. This hasn't really caught on. Here are the reasons I think spinlocks would be better: At least in synthetic benchmarks that I did, it's several times faster than OS critical sections when there's contention for the memory allocator/GC lock. Edit: Empirically, using spinlocks didn't even have measurable overhead in a single-core environment, probably because locks need to be held for such a short period of time in a memory allocator. Memory allocations and similar operations usually take a small fraction of a timeslice, and even a small fraction of the time a context switch takes, making it silly to context switch in the case of contention. A garbage collection in the implementation in question stops the world anyhow. There won't be any spinning during a collection. Are there any good reasons not to use spinlocks in a memory allocator/garbage collector implementation?

  • Troubles with NSString writeToFile

    - by Jesse
    Hi everyone, I have been working on a simple text editor in Cocoa/Objective-C for a practice project and I have come across an error that I would never have expected. I have an NSString for my file's contents as well as an NSString for it's path. When I attempt to write the contents to a file, I use the following method: [FileContents writeToFile: CurrentFileName atomically: NO encoding: NSStringEncoding error: nil]; I've used this method many times without error yet today, I am getting an error: "Expected expression before 'NSStringEncoding'" If anyone can help me out with this it would be greatly appreciated. I can't figure out what could be causing the error. Thanks a lot!

  • Bash intercepting wildcard in script

    - by MrRoth
    I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

    I'm having trouble with this reg expression which i belive is correct, but it is not working. What im trying to do is redirect bunch of urls containing a specific string like this: http://www.example.com/**undesired-string**_another-string to http://www.example.com/**new-string**_another-string and http://www.example.com/folder/**undesired-string**/another-string to http://www.example.com/folder/**new-string**/another-string So i have this code in the .htaccess: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule (.+)+(undesired-string)+(.+) $1new-string$2 [R=301,L] </IfModule> This should replace ANY undesired-string in any url to new-string, but it is not working, any idea why ?
