  • Validate numeric text field in jquery

    - by mcxiand
    I have this code in jquery to prevent non-numeric characters being inputted to the text field $("#NumericField").numeric(); Now, on the text field i cant input non-numeric characters. That is OK. The problem here is if the user will paste on the text field with non numeric characters. Is there a way/method to disable pasting if the value is non-numeric? Or is there any other approach to handle this situation that you can share?

  • Working with arrays of lists pattern in java

    - by Mad Wombat
    I am writing a card game in java where I need to spread cards from a deck into several columns until I have fixed amount of cards left. This is how I do this. public class Column extends ArrayList {} List deck = Cards.createNewDeck(); Column[] columns = new Column[10]; int c = 0; while (deck.size() 50) { if (c == 10) { c = 0; } if (columns[c] == null) { columns[c] = new Column(); } columns[c].add(Cards.dealTopCard(deck)); c += 1; } This somehow seems clunky. Is there a more readable/comprehensive way of doing the same thing?

  • Manipulating collections & the ViewModel pattern

    - by Kragen
    I'm relatively new to WPF, and I'm having trouble with what I'm fairly certain is a relatively simple problem. I have my underlying data object, a Person: class Person { public string Surname {get; set; } public string Firstname {get; set; } public List<Address> Addresses {get; } } And I wish to display and edit this object in my WPF app. To this end I've created a ViewModel that I bind to in my xaml: class PersonViewModel { public string Fullname {get; } public ObservableCollection<AddressViewModel> Addresses {get; } } This is fine, except when it comes to manipulating my Address collection, where I can't work out what I should be doing: Should I add methods AddAddress, RemoveAddress etc... to my PersonViewModel class for manipulating my collection with instances of AddressViewModel Should I just add instances of AddressViewModel to my Addresses observable collection Both of the above seem a bit messy - is there a better way of dealing with collections?

  • highlight parent window text when spell checking from child window

    - by Bo Gusman
    I'm working on a simple spell checking app for a lecture that I'm giving. I've got the basic spell checking code working just fine using a child form and NHunspell - great lib, by the way. However, I'd like for the parent textbox to show the highlighted text for reference, and while I'm setting the SelectedText properties accordingly, the text is not highlighted in the parent. Canceling the child window and the parent text is highlighted. Anybody know how I can do this?

  • Zedgraph textobj X location depends on text length?

    - by Tony_Henrich
    I have a Zedgraph textobj which I want to place always in the same x, y position (ASP.NET image). I noticed that the text doesn't always show in the same starting x position. It shifts depending on the text's length. I tried to have the text to have the same length by padding it with spaces. It helped a little but the result is not always consistent. I am using PaneFraction for coordType. What's the proper method to have a piece of text to always show in the same x position. I am using textobj as a title because the native title property always shows up centered and I need my title be left aligned to the graph.

  • What are useful functions for drawing text (MFC)?

    - by kobac
    I'm creating a line chart control, and I need to write (or better say draw) the axis names and axis values. I found DrawText and TextOut functions, but the text they show is flickering and don't know how to set the font and text orientation (I will need vertical text orientation as well as horizontal). Are there any other functions you could recoommend or how to use these stated above and get the results I need? Thanks in advance. Cheers.

  • Put text input inside label for radio button?

    - by Martijn
    I'm trying to make a radio group specifying a bunch of options, and an extra option "other" with a text input to specify. The code for this particular radio button I'm using is <input type='radio' name='RadioInput' value='Other' id='RadioInput_Other' /> <label for='RadioInput_Other'>Ohter: <input type='text' name='RadioInput_Other_Value' id='RadioInput_Other_Value' value='' /> </label> The idea is that if you give focus to the text input, the radio button corresponding to it is selected. The code above almost does this (since the text input is inside the label). However, it also shifts focus to the radio button (which is annoying, since whatever you type next is lost). Is there any way to prevent this using XHTML1.0 / CSS2? Preferably without using javascript.

  • Design Pattern for error handling in ASP.NET 3.5 site

    - by Kevin
    I am relatively new to ASP.NET programming, and web programming in general. We have a site we recently ported from .NET 1.1 to 3.5. Currently we have two methods of error handling: either catching the error during data load on a page and displaying the formatted error in a label on the page, or redirecting to a generic error page. Both of these are somewhat annoying, as right now I'm trying to redesign how our errors are displayed. We are soon moving to Master pages, and I'm wondering if there is a way to "build in" an error handling control. What I mean by this is using a ASP.NET user control I've designed that simply gets passed the error string returned from the server. If an error occurs, the page would not display the content, and instead display the error control. This provides us with the ability to retain the current banner/navigation during an error (which we don't get with the generic error page), as well as keeping me from having to add the control to every aspx page we have (which I have to do with using the label-per-page system). Does something like this make sense? Ultimately I just want to have the error control added to a single page, and all other pages have access to it directly. Is this something Master pages help with? Thanks!

  • Crystal report - Conversion from text to decimal ?

    - by 123rmn
    I have a crystal report, which takes data from an XML template. For a particular field of report, say 'Cost' the database stored procedure send data to XSD file in decimal format , but when the crystal report displays data picking from XSD, it is rounded off. When i right click on other data fields of report, I can see 'Field:table1.columnname',. But when i click on 'Cost' field, it shows 'Text:'. To my understanding, this is a text field which is mapped to pick data from XSD and since the type is text, it gives result in text hence truncating the decimal. Please suggest how can I get decimals here. P.S: This code was created by someone else, so i have no idea on what they had set at that time. I have to fix it and i have no clue about it.

  • Grails pattern to reuse template on error

    - by bsreekanth
    Hello, I have a gsp template, where the data for create view is passed through the controller. def create = { def bookInstance = new Book() bookInstance .properties = params def map = getDefaultValues() render(template: "create", model: [bookInstance : bookInstance , title: map.title, somelist: somelist ....]) the gsp template <g:select optionKey="id" from="${somelist}" name="somelist.id" value="${bookInstance ?.somelist?.id}" noSelection="['null': '']"></g:select> now, in the save method, if there is an error, it returns currently populated and validated instance (default scaffold implementation) render(template: "create", model: [bookInstance : bookInstance ]) But the fields in the gsp (error page rendered from save action) is empty. I could see the reason as it looks the value in "${somelist}" , but it is not used in save method. Do i just need to check for null in the gsp and use whichever map is available, or any better method (passing all the map in the save method is not an option) .. thanks in advance..

  • WHy am I unable to add text along with <%# Container.DataItem %> in repeater in user control

    - by Jamie Hartnoll
    I have a User Control which is dynamically placed by CodeBehind as follows: Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control) If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then mainMenu.Controls.Add(myControl) End If As per an example from my previous question on here. Within this Control is a repeater which calls a database to generate values. My Repeater mark-up is as follows <asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount"> <ItemTemplate> <p id='locationQuestions' title='<%# Container.DataItem %>' runat='server'></p> </ItemTemplate> </asp:Repeater> The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p to print to the browser like this is some text DATA_ITEM_OUTPUT When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code. It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text, I am stumped to fix it! I'm new to .net and using vb.net, please could someone point me in the right direction?

  • (static initialization order?!) problems with factory pattern

    - by smerlin
    Why does following code raise an exception (in createObjects call to map::at) alternativly the code (and its output) can be viewed here intererestingly the code works as expected if the commented lines are uncommented with both microsoft and gcc compiler (see here), this even works with initMap as ordinary static variable instead of static getter. The only reason for this i can think of is that the order of initialization of the static registerHelper_ object (factory_helper_)and the std::map object (initMap) are wrong, however i cant see how that could happen, because the map object is constructed on first usage and thats in factory_helper_ constructor, so everything should be alright shouldnt it ? I am even more suprised that those doNothing() lines fix the issue, because that call to doNothing() would happen after the critical section (which currently fails) is passed anyway. EDIT: debugging showed, that without the call to factory_helper_.doNothing(), the constructor of factory_helper_ is never called. #include <iostream> #include <string> #include <map> #define FACTORY_CLASS(classtype) \ extern const char classtype##_name_[] = #classtype; \ class classtype : FactoryBase<classtype,classtype##_name_> namespace detail_ { class registerHelperBase { public: registerHelperBase(){} protected: static std::map<std::string, void * (*)(void)>& getInitMap() { static std::map<std::string, void * (*)(void)>* initMap = 0; if(!initMap) initMap= new std::map<std::string, void * (*)(void)>(); return *initMap; } }; template<class TParent, const char* ClassName> class registerHelper_ : registerHelperBase { static registerHelper_ help_; public: //void doNothing(){} registerHelper_(){ getInitMap()[std::string(ClassName)]=&TParent::factory_init_; } }; template<class TParent, const char* ClassName> registerHelper_<TParent,ClassName> registerHelper_<TParent,ClassName>::help_; } class Factory : detail_::registerHelperBase { private: Factory(); public: static void* createObject(const std::string& objclassname) { return getInitMap().at(objclassname)(); } }; template <class TClass, const char* ClassName> class FactoryBase { private: static detail_::registerHelper_<FactoryBase<TClass,ClassName>,ClassName> factory_helper_; static void* factory_init_(){ return new TClass();} public: friend class detail_::registerHelper_<FactoryBase<TClass,ClassName>,ClassName>; FactoryBase(){ //factory_helper_.doNothing(); } virtual ~FactoryBase(){}; }; template <class TClass, const char* ClassName> detail_::registerHelper_<FactoryBase<TClass,ClassName>,ClassName> FactoryBase<TClass,ClassName>::factory_helper_; FACTORY_CLASS(Test) { public: Test(){} }; int main(int argc, char** argv) { try { Test* test = (Test*) Factory::createObject("Test"); } catch(const std::exception& ex) { std::cerr << "caught std::exception: "<< ex.what() << std::endl; } #ifdef _MSC_VER system("pause"); #endif return 0; }

  • How to stop HTML text in textarea to be interpreted as code

    - by Myone
    I have a textarea that users can edit. After the edit I save the text in a PHP variable $bio. When I want to display it I do this: <?php $bio = nl2br($bio); echo $bio; ?> But if a user for example types an HTML command like "strong" in their text my site will actually output the text as bold. Which is nothing I want. How can I print/echo the $bio on the screen just as text and not as HTML code? Thanks in advance!

  • ie7 preserve whitespace on dynamically injected text

    - by Rajat
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script type="text/javascript"> function init(){ document.getElementById('test2').innerHTML = '1 2'; } </script> <style type="text/css"> #test{ white-space:pre; } #test2{ white-space:pre; } </style> <title></title> </head> <body onload="init();"> <div id="test"> 1 2 </div> <div id="test2"></div> </body> </html> Here is an example page showing my problem. I have two divs. Each has this text '1 2' with white-space. The only difference is that one is injected dynamically and one is in the html itself. If you open the above page in IE7, the text in div test2 doesn't respect white space. How can i get the same behavior for the text that is dynamically injected?? P.S. My doctype is triggering standards mode on IE7.

  • what pattern to use for multi-argument method?

    - by Omid S
    I have a method with the following signature: foo (Sample sample, Aliquot aliquot) "foo" needs to alter a Sample object, either the first argument or from the second argument it can extract its Sample. For example: foo (Sample sample, Aliquot aliquot) { Sample out = null; if (sample != null) out = sample else out = aliquot.getSample() return out; } But that is so un-elegant, other than reading the API a developer does not know the reference of the first argument overrides the Sample of the second argument. Now, I could change "foo" to foo (SomeMagicalObject bar) where SomeMagicalObject is a tuple for Sample and Aliquot and holds some logic ... etc. But I am wondering, are there some patterns for this question?

  • trying to read a delimited text file from resources - but it wont run

    - by Bigfatty
    I'm having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it messes up my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. Could some one please help?

  • Inconsistent height of text input elements between Firefox and WebKit

    - by Trevor Burnham
    OK, I realize that this is something of an eternal question, but here goes: I've got a single text input, <input type="text" name="whatever" /> and I've specified its font-family, font-size and padding. Yet, even on the same machine (my Mac, let's say), the input has a different height in Firefox (3.6) than it does in Chrome or Safari. Specifically, Firefox adds a little bit more padding below the text. And no, specifying height in pixels doesn't achieve consistency either. Is there any way to achieve text input height consistency across Gecko- and WebKit-based browsers (let alone IE and Opera) without resorting to JavaScript? And if I must use JavaScript, has someone already devised a jQuery plugin or something to easily do this? Update: Here's what not to do. The jqTransform plugin lets you skin form elements and promises that they'll look the same across browsers. Here's how the demo input looks in Chrome 5 on my Mac: and here's how the same input looks in Firefox 3.6.4: I haven't altered these screenshots in any way, just cropped them. Now, my first reaction is, "Ugh, I don't want to support Firefox." But there are currently more Firefox users than Safari and Chrome users combined, so that's not an option. Someone, please help! I just want my forms to look the same across modern, standards-compliant browsers! And by "look the same," I'm not talking about the outline on selection or anything like that; I'm just talking about having the same width, height, and text placement!

  • Using jQuery to echo text

    - by susmits
    Is it possible to use jQuery to echo text in place of a script tag? More precisely, is there a way to accomplish <script type="text/javascript"> document.write("foo"); </script> ... without the use of document.write? I am not happy about using document.write after reading this. I am aware that I could alternatively do this: <span id="container"></span> <script type="text/javascript"> $("#container").text("foo"); </script> However, I'm interested to see if there's a way to do it without using a container element, preferably using jQuery. Thanks in advance!
