  • Using different validation rules based on user input.

    - by chiefanov
    I have a simple form: a combobox and a textbox. My combobox has 2 values: A and B. When value A is selected I want textbox to use a validation rule. When value B is selected there should be no validation rules applied to the textbox. I've read an article that has a solution and I'm trying to use it, but had no luck so far, and I think there might be a more elegant solution. Has anyone done anything like this before? Any ideas are highly appreciated.

  • JavaScript prototype(ing) question

    - by OneNerd
    Trying to grasp Prototyping in Javascript. Trying to create my own namespace to extend the String object in JavaScript. Here is what I have so far (a snippet): var ns { alert: function() { alert (this); } } String.prototype.$ns = ns; As you can see, I am trying to place what will be a series of functions into the ns namespace. So I can execute a command like this: "hello world".$ns.alert(); But the problem is, the this doesn't seem to reference the text being sent (in this case, "hello world"). What I get is an alert box with the following: [object Object] Not having a full grasp of the object-oriented nature of JavaScript, I am at a loss, but I am guessing I am missing something simple. Does anyone know how to achieve this? Thanks -

  • Rails 2.3.5: How to handle this type of validation

    - by randombits
    The use case is simple. I allow users to enter in an expiration field which needs to be between 1 and 15 into a form. The model takes that number and converts it into a datetime (such as adding 15 days from today) and stores it in the database. What's the correct way to actually validate that though? Do I validate against the datetime format that gets persisted in the database or the select box (1..15) that the user gets to pick through the form? I want to be able to validate that the user is putting in 1..15.. How is this done with ActiveRecord validation in Rails 2.3.5?

  • Kohana 3.2 useradmin routing issue

    - by user1789926
    I am new to kohana and am developing a simple application that is using the useradmin module from http://blog.mixu.net. I am having, what I think, an understanding problem. At present the action_index redirects to user/profile when a non admin user logs in. I want to go to a controller called home instead. I want to redirect to home/index.php I have tried simply changing the redirect and this does not work. I am suspecting I need to do something with routes to get me to home/index but I can not work out what I should be doing. I would really appreciate it if someone could steer me in the right direction here.

  • Search for all instances of certain annotation type

    - by user1064918
    Suppose I have this annotation @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.FIELD) public @interface Name { String value(); } This is going to be used as follows @Name("name1") public static Foo foo = new Foo(); I have multiples of these across my project source files. Is there an fairly simple way to search and collect all those "foo"s that're preceded by @Name? In other words, I'd like to write a method that would return a Set<Foo> containing these. Thanks!!!

  • PHP: Iterate through folders and display HTML contends

    - by Mestika
    Hi, I’m currently trying to develop a method to get a overview of all my different web templates I’ve created and (legally) downloaded over the years. I thought about a displaying them like Wordpress is previewing it’s templates view a small preview windows, displaying the concrete file with styles and everything. How to divide them into rows and columns and create AJAX modal window open on preview and pagination and so on I believe I can manage, but it is the concept itself about iterate over several folders then find all index.htm / index.html pages and displaying them. I’ve not worked very much with directories in PHP and the only references and code stumps I’ve found so far is just to list all the files in a certain directory like, what it contains. I would be really grateful if someone knew about a script, a function, snippet or just could get me a nudge in the right direction to create such a (probably simple) preview function. Sincere Mestika

  • (g)Vim with version control like Eclipse

    - by Somebody still uses you MS-DOS
    I was an Eclipse user, now I have to use Vim in my machine. I used to "compare" a file I edited with a CVS repository to do merges an commit the files, using a context menu and my mouse. Is this possible in Vim? Opening a vimdiff for a file before commiting, and commit it from vim itself? And how is that supposed to work? I'm supposing I would be editing a file. Then, I want to see the modifications. I run vimdiff in gvim, and a new window (or buffer) is opened. I run the modifications, save what is applicable (using vimdiff commands), and commit running another command. Is this all transparent in vim? Do I have to keep getting out of vim to my terminal, or can all be done inside it? Do I need to use some plugins, or just really simple functions inside my vimrc?

  • Getting a java collection of objects in Alphabetical order

    - by MichaelMcCabe
    I have a question that I dont really know where to start. So I thought i'd ask it here. Basically, I have a drop down with names in it. I want these names to be in alphabetical order. Populating the drop down happens as follows; I query a database and pull down an Id and Name, make a object called "UserList", and set the name and id variables with what I get back. I then add this object to an ArrayList. I do this over and over. I then convert this collection to an array, and pass it to my JSP page using session.setAttribute("userList", UserList); I then populate the drop down as below. <c:forEach items="${usersCompanysList}" var="c" > There probably is a simple answer but how to I sort these names?

  • Do I need the text "_size" in the my.cnf file for mysql 5.1?

    - by chongman
    This is a pretty simple question about setting parameters in the my.cnf file for mysql 5.1. This page gives me the parameters I can tune: http://dev.mysql.com/doc/refman/5.0/en/server-parameters.html and so I think I would need to write key_buffer_size = 256M But when I open my current my.cnf, it has the line: key_buffer = 16M My question is, do I need "key_buffer_size" or "key_buffer" or does it not matter which I use? And, how would I know if something in the my.cnf is incorrect? Where's the daemon start log file? I am running ubuntu; I think version 8.04 LTS

  • How to handle the close (big X) button at the source?

    - by Simon T.
    We would like under some circumstances to block the action of the close button in the title bar. The problem is that it's a MDI applications and it seems that we will have to add code in each forms to cancel the operation in the Closingevent handler. It seems that the child forms are the first to receive the event. There is no way to add code at a single place to cancel the close operation. Information on how the close event is propagated to the child form would be welcome. Is there a simple way of doing what we want to do?

  • DataContext Doesn't Exist in Dynamic Data Project?

    - by davemackey
    This is really annoying...and I know it is something extremely simple... 1. I create a new Dynamic Data project. 2. I add a LINQ-to-SQL class and drag and drop some tables onto the class. 3. I open the global.asax.vb and uncomment the line: DefaultModel.RegisterContext(GetType(YourDataContext), New ContextConfiguration() With {.ScaffoldAllTables = True}) I remove YourDataContext and replace it with the DataContext from my LINQ-to-SQL class: DefaultModel.RegisterContext(GetType(NorthwindDataContext), New ContextConfiguration() With {.ScaffoldAllTables = True}) I then try to debug/build/etc. and receive the following error: Type 'NorthwindDataContext' is not defined Why is it not defined? It seems like its not recognizing I created the DBML file.

  • Problem removing a dynamic form field in jquery

    - by rshivers
    I'm trying to remove a dynamic form field by click a button. It will also subtract whatever values it had from the total amount from my calculation. This is the code: function removeFormField(id) { var id = $(id).attr("name"); $('#target1').text($("#total" + id).map(function() { var currentValue = parseFloat(document.getElementById("currentTotal").value); var newValue = parseFloat($("#total" + id).text()); var newTotal = currentValue - newValue; document.getElementById("currentTotal").value = newTotal; return newTotal; }).get().join()); $(id).remove(); } Okay, it will do the subtraction portion of the code with no problem, this issue is with the last line to remove the field. If I comment out the rest of the code it will work, but not with the rest of the code. I know this is something simple, yet I can't seem to wrap my mind around it. Can someone please help?

  • Change URL of a saved HTML file

    - by Paul Camilleri
    I am new to HTML so this question might sound a bit lame. Anyways I have a saved webpage on my desktop that when i open it in google chrome i want it to show a specific URL instead of its current location. Any ideas how i might get this to work?

  • How is this problem usually solved without using sever-side scripting?

    - by cyggi
    Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

    I have a file in the format: Port Number IP address Port Number IP address (Not sure how the output will be displayed here but let me tell you they are on separate lines) and so on.... I use the command grep -C 1 'port number' file.txt i.e. I want all IP addresses corresponding to a particular port. Making it simple, I want the next line matching a regular expression. Like if my regular expression matches line 2,4 and 6 then I want lines 3, 5 and 7 to be printed. How to do that?

  • Grails searchable plugin with hasMany

    - by user2624442
    I am using grails searchable plugin to search my domain classes. However, I cannot yet search by my hasMany (skills and interests) fields even though they are of the simple type String. This is my domain class: class EmpactUser { static searchable = [except: ['dateCreated','password','enabled','accountExpired','accountLocked','passwordExpired']] String username String password boolean enabled = true boolean accountExpired boolean accountLocked boolean passwordExpired String email String firstName String lastName String address String phoneNumber String description byte[] avatar byte[] resume Date dateCreated static hasMany = [ skills : String, interests : String, // each user has the ability to list many skills and interests so that they can be matched with a project. ] static constraints = { username blank: false, unique: true password blank: false email email: true, blank: false firstName blank: false lastName blank: false description nullable: true address nullable: true avatar nullable: true, maxSize: 1024 * 1024 * 10 resume nullable: true, maxSize: 1024 * 1024 * 10 phoneNumber nullable: true, matches: "/[(][+]d{3}[)]d+/", maxSize: 30 } } This is the code I am using to search: def empactUserList = EmpactUser.search( searchQuery, [reload: false, result: "every", defaultOperator: "or"]) Am I missing something?

  • Query returning an ascending group number

    - by Dougman
    I have a query like below that has groups (COL1) and that group's values (COL2). select col1, col2 from (select 'A' col1, 1 col2 from dual union all select 'A' col1, 2 col2 from dual union all select 'B' col1, 1 col2 from dual union all select 'B' col1, 2 col2 from dual union all select 'C' col1, 1 col2 from dual union all select 'C' col1, 2 col2 from dual ) order by col1, col2; The output of this query looks like: COL1 COL2 ---- ---- A 1 A 2 B 1 B 2 C 1 C 2 What I need is a query that will return an ordered number increasing for each different group (COL1). It seems like there would be a simple way to accomplish this (maybe with analytics) but for some reason it is escaping me. GRPNUM COL1 COL2 ------ ---- ---- 1 A 1 1 A 2 2 B 1 2 B 2 3 C 1 3 C 2 I am running Oracle 10gR2.

  • How to define a ternary operator in Scala which preserves leading tokens?

    - by Alex R
    I'm writing a code generator which produces Scala output. I need to emulate a ternary operator in such a way that the tokens leading up to '?' remain intact. e.g. convert the expression c ? p : q to c something. The simple if(c) p else q fails my criteria, as it requires putting if( before c. My first attempt (still using c/p/q as above) is c match { case(true) = p; case _ = q } another option I found was: class ternary(val g: Boolean = Any) { def |: (b:Boolean) = g(b) } implicit def autoTernary (g: Boolean = Any): ternary = new ternary(g) which allows me to write: c |: { b: Boolean = if(b) p else q } I like the overall look of the second option, but is there a way to make it less verbose? Thanks

  • Sorting a listview (Win32/C++)

    - by Zenox
    I'm trying to sort a listview when the user clicks on the column header. I am catching the LVN_COLUMNCLICK notification like so: case LVN_COLUMNCLICK: { NMLISTVIEW* pListView = (NMLISTVIEW*)lParam; BOOL test = ListView_SortItems ( m_hDuplicateObjectsList, ListViewCompareProc, pListView->iSubItem ); break; } However it seems to fail. My test variable is FALSE and my ListViewCompareProc never gets hit (it has a simple return 1 while I am trying to hit a debug point inside of it). Is there something I am missing for sorting a listview?

  • How do I create if statements in php to perform a specific action depending on what form has string in it

    - by user1637284
    Im trying to create a grid on my page in each cell there will be a simple one line form. If a person enters data into lets say FieldA I would like the php to perform actionA but if the data was entered in FieldF I would like actionF performed. Is this possible without having to create a php for each cell and upload all those php files? Or is there a way to perform the GET method in each form to append the data to the end of the action url without the field name showing (ie sample.com/somestuff/fieldA instead of sample.com/somestuff/fieldname=fieldA) thus not needing php at all?

  • Can a raw Lucene index be loaded by Solr?

    - by wynz
    Some colleagues of mine have a large Java web app that uses a search system built with Lucene Java. What I'd like to do is have a nice HTTP-based API to access those existing search indexes. I've used Nutch before and really liked how simple the OpenSearch implementation made it to grab results as RSS. I've tried setting Solr's dataDir in solrconfig.xml, hoping it would happily pick up the existing index files, but it seems to just ignore them. My main question is: Can Solr be used to access Lucene indexes created elsewhere? Or might there be a better solution?

  • && (AND) and || (OR) in Java IF statements

    - by Azimuth
    My question might be very basic but still I think it worths to ask. I have the following code: if(!partialHits.get(req_nr).containsKey(z) || partialHits.get(req_nr).get(z) < tmpmap.get(z)){ partialHits.get(z).put(z, tmpmap.get(z)); } where partialHits is a HashMap. What will happen if the first statement is true? Will Java still check the second statement? Because in order the first statement to be true, the HashMap should not contain the given key, so if the second statement is checked, I will get NullPointerException. So in simple words, if we have the following code if(a && b) if(a || b) would Java check b if a is false in the first case and if a is true in the second case?
