  • jquery keypress iterate through each loop?

    - by user239831
    hey guys, probably a simpel question, however couldn't find anything online. i have a list with search results and i want to be able to navigate through the list with my up and down keys. if (e.keyCode == 40) { //down //alert('down'); $('#searchresults ul li').each(function() { }); } if (e.keyCode == 38) { //up //alert('up'); } if (e.keyCode == 13) { //enter //alert('enter'); } the searchresults look like this: <ul> <li class="matched"><a href="link1">link1</a></li> <li class="matched"><a href="link2">link2</a></li> <li class="matched"><a href="link3">link3</a></li> </ul> So basically i just want to be able to navigate through my searchresults with the up and down keys. the selection of the current element should maybe just change the background color and when i press enter the linked and matched element is fired. any idea how i can iterate through the searchresults? thank you

  • Mapping words to numbers with respect to definition

    - by thornate
    As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

  • ^+Left Arrow and ^+Right Arrow suddenly stopped working on OS X

    - by user293261
    Hello. I'm not really sure what to make of this. The key combination of ^← and ^→ have stopped working for one of the two users on my OS X installation. I use these keys all the time (switching tabs in terminal, IntelliJ primarily), and it's driving me crazy. On one user account, it works fine. On the other, it doesn't. This happened today and nothing significant comes to mind that would have caused some weird keybinding issue. If anyone has heard of or experienced anything like this, I would very much appreciate your advice! Thanks.

  • .NET ValidationRule problem

    - by PaN1C_Showt1Me
    Hi ! I have a control with this validation <MyPicker.SelectedItem> <Binding Path="Person.Value" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" NotifyOnValidationError="True"> <Binding.ValidationRules> <rules:MyValidationRule ValidationType="notnull"/> </Binding.ValidationRules> </Binding> </MyPicker.SelectedItem> This is the Validation Class: class MyValidationRule : ValidationRule { private string _validationType; public string ValidationType { get { return _validationType; } set { _validationType = value; } } public override ValidationResult Validate(object value, CultureInfo cultureInfo) { ValidationResult trueResult = new ValidationResult(true, null); switch (_validationType.ToLower()) { case "notnull": return value == null ? new ValidationResult(false, "EMPTY FIELD") : trueResult; default: return trueResult; } } } Question: When the property is changed, then the Validate( ) method is called which is correct. But to call this method at the very beginning when the MyControl is created? I need to prove immediate after initialize if the there's a null value in the control (and display a validation error)

  • Reading a text file in c++

    - by Yavuz Karacabey
    string numbers; string fileName = "text.txt"; ifstream inputFile; inputFile.open(fileName.c_str(),ios_base::in); inputFile >> numbers; inputFile.close(); cout << numbers; And my text.txt file is: 1 2 3 4 5 basically a set of integers separated by tabs. The problem is the program only reads the first integer in the text.txt file and ignores the rest for some reason. If I remove the tabs between the integers it works fine, but with tabs between them, it won't work. What causes this? As far as I know it should ignore any white space characters or am I mistaken? If so is there a better way to get each of these numbers from the text file?

  • Using WINAPI ReadConsole

    - by Jim Fell
    I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application. CONSOLE_READCONSOLE_CONTROL tControl; char pStr[65536]; DWORD dwBufLen = 1; DWORD dwCtl; tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL ); tControl_c.nInitialChars = 0; tControl_c.dwControlKeyState = 0; tControl_c.dwCtrlWakeupMask = NULL; pBuf[0] = 0x00; do { ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl ); } while ( pStr[0] == 0x00 ); The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

    I have a e-mail address validator but I need to add special characters as valid for example ü, ç...

  • How can I tweak this elisp function to distinguish between C-d & DEL?

    - by Fletcher Moore
    Here's my current function (blindly copy-pasted from a website) (defun tweakemacs-delete-one-line () "Delete current line." (interactive) (beginning-of-line) (kill-line) (kill-line)) (global-set-key (kbd "C-d") 'tweakemacs-delete-one-line) There are two quirks here that I want to get rid of. 1) This actually rebinds DEL to the same function. I want my DEL to remain "delete one character". 2) There needs to be a condition where it will not double-kill if the line is only a newline character.

  • Shortcut to create automatic properties using Visual Studio 2008/2010 or Resharper 5

    - by Piers Myers
    I have a class that contains a load of properties that contain results of some calculations e.g: public class Results { public double Result1 { get; set; } public double Result2 { get; set; } } In a different class I am doing calculations to populate the above properties, e.g: public class Calc { private Results Calc() { Results res = new Results(); res.Result1 = ... some calculation res.Result2 = ... some other calculation res.Result3 = ... // not yet defined in 'Results' class return res; } } When I am writing the Calc class, 'Result3' will be highlighted in red as it is not yet defined in the 'Results' class. Currently I am using the Resharper ALT-Enter shortcut, selecting "Create Property 'Result3'" which will create the following code int the 'Results' class: public double Result3 { get { throw new NotImplementedException(); } set { throw new NotImplementedException(); } } Which I need to manually change to: public double Result3 { get; set; } Then I use the CTRL-Shift-Backspace shortcut to take me back to the 'Calc' class. How can I easily create automatic properties in the 'Results' class if they are not yet defined directly from the 'Calc' class?

  • keybd_event is not working right =(

    - by user302131
    I can't get this to work right. This should press left for 1 second then wait 10 seconds, then right 1 second, etc.: keybd_event(0x25, 0xCB, 0, 0); // press left cout << "Ldown\n"; // so i know it worked Sleep(1000); // hold it for 1sec keybd_event(0x25, 0xCB, KEYEVENTF_KEYUP, 0);// let go of the key cout << "Lup\n"; // so i know i let go Sleep(10000); // Sleep for 10secs keybd_event(0x27, 0xCD, 0, 0); // press right cout << "Rdown\n"; // so i know i pressed right Sleep(1000); // sleep 1sec keybd_event(0x27, 0xCD, KEYEVENTF_KEYUP, 0);// let go of the key cout << "Rdown\n"; // so i know i let go. This is in a loop but it wont do anything :( Unless I close the program before the key is let go, then it will just keep the key down until I press the key again. I know you can use only one key code if you want but I need to use both. So what am I missing?

  • multiple validation errors showing up for single property

    - by Dave K
    i'm often getting multiple errors showing up for an individual property, when I'd like them to be prioritized, as in, if Required is satisfied, check StringLength, but if Required fails, show that message only. I'm getting inconsistent behavior here, and I'm curious as to how the framework determines this priority? has anyone else had problems with this? Thanks!

  • How do I make faint words in search bar that go away when you click/type?

    - by Razor Storm
    So, for instance facebook's search bar has faint word that says "search", but when you click on the bar, it becomes blank and you may begin typing, when you click away the "search" goes back. Similarly, SO's ask a question title box has faint words that go away when you start typing. I'm not too sure what this effect is called, but I'm wondering if theres a jQuery plugin that helps to achieve this. This isn't particularly difficult to program, but I thought why reinvent the wheel if someone already made a plugin for it.

  • Sanitizing DB inputs with XSLT

    - by azathoth
    Hello I've been looking for a method to strip my XML content of apostrophes (') like: <name> Jim O'Connor</name> since my DBMS is complaining of receiving those. By looking at the example described here, that is supposed to replace ' with '', I constructed the following script: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*" /> </xsl:copy> </xsl:template> <xsl:template name="sqlApostrophe"> <xsl:param name="string" /> <xsl:variable name="apostrophe">'</xsl:variable> <xsl:choose> <xsl:when test="contains($string,$apostrophe)"> <xsl:value-of select="concat(substring-before($string,$apostrophe), $apostrophe,$apostrophe)" disable-output-escaping="yes" /> <xsl:call-template name="sqlApostrophe"> <xsl:with-param name="string" select="substring-after($string,$apostrophe)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string" disable-output-escaping="yes" /> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="node()|@*"> <xsl:apply-templates name="sqlApostrophe"/> </xsl:template> </xsl:stylesheet> However, the processor isn't accepting it. What am I missing here? Is there a better way to get rid of the apostrophes? Perhaps another approach for sanitizing DB inputs by using XSLT? Thanks for your help

  • Using unless in rails uniqueness validation

    - by dunxd
    I am just starting out in Rails, and trying to develop a simple application. I need to validate three values submitted to the application - each must meet the same validation criteria. The validation is pretty simple: Value is valid if unqiue, null or equal to "p" or "d". The following gets me halfway there: validates_uniqueness_of :value1, :value2, :value3, :allow_nil => true I think I can use :unless to check whether the value is either "p" or "d", however I can't figure out how. I guess I am trying to combine validates_uniqueness_of with validates_inclusion_of. Any suggestions?
