  • create_function with default parameter values?

    - by SoLoGHoST
    Ok, I'm looking into using create_function for what I need to do, and I don't see a way to define default parameter values with it. Is this possible? If so, what would be the best approach for inputting the params into the create_function function in php? Perhaps using addslashes? Well, for example, I have a function like so: function testing($param1 = 'blah', $param2 = array()) { if($param1 == 'blah') return $param1 else { $notblah = ''; if (count($param2) >= 1) { foreach($param2 as $param) $notblah .= $param; return $notblah; } else return 'empty'; } } Ok, so how would I use create_function to do the same thing, adding the parameters and their default values? The thing is, the parameters are coming from a TEXT file, as well as the function itself. So, wondering on the best approach for this using create_function and how exactly the string should be parsed. Thanks :)

  • Getting Assert to work in Visual C++ Unit Tests?

    - by garsh0p
    I'm using Visual Studio 2008's built in testing framework in my Visual C++ project. I'm adding a new Test Project, then a new Unit Test. However, I can't use any of the functions provided by Assert. Assert shows up in the Intellisense, but I can't do anything with it. I've done unit tests fine in Visual C#. Am I forgetting to do anything? EDIT: There isn't much code because everything I'm doing is auto-generated by Visual Studio 2008. Here are the steps I'm doing: File - New Project - Visual C++ - General - Empty Project Right click solution in Solution Explorer - Add - New Project... Visual C++ - Test - Test Project Open UnitTest1.cpp (auto-generated) Go to TestMethod1() From here, when I try to use the Assert class (like Assert.AreEqual), I can't do it. If I do the same in a Visual C# project, it works fine.

  • jquery.validation - how to ignore default values when validating mandatory fields

    - by jack
    I am using jquery validation plugin to validate a registration form. Each text input field has instructions pre-filled as values in the input box ex: for a text-input box id='Name', the default value will be set to 'Enter Your Name'. I have pasted below sample code: <input type="text" id="Name" value="Enter Your Name" onfocus="if(this.value == 'Your Name'){this.value = '';}" type="text" class="required" onblur="if(this.value == ''){this.value='Your Name';}" size="25" /> What I need to know is how to specify in the validation rule such that the plugin throws a required field error if the input box contains either the default message or empty values. Help much appreciated.

  • Chess board position numbers in 6-rooted-binary tree?

    - by HH
    The maximum number of adjacent vertices is 6 that corresponds to the number of roots. By the term root, I mean the number of children for each node. If adjacent square is empty, fill it with Z-node. So every square will have 6 nodes. How can you formulate it with binary tree? Is the structure just 6-rooted-binary tree? What is the structure called if nodes change their positions? Suppose partially ordered list where its units store a large randomly expanding board. I want a self-adjusting data structure, where it is easy to calculate distances between nodes. What is its name?

  • Multi-threaded downloader in C# question

    - by blez
    Currently I have multi-threaded downloader class that uses HttpWebRequest/Response. All works fine, it's super fast, BUT.. the problem is that the data needs to be streamed while it's downloading to another app. That means that it must be streamed in the right order, the first chunk first, and then the next in the queue. Currently my downloader class is sync and Download() returns byte[]. In my async multi-threaded class I make for example, list with 4 empty elements (for slots) and I pass each index of the slot to each thread using the Download() function. That simulates synchronization, but that's not what I need. How should I do the queue thing, to make sure the data is streamed as soon as the first chunk start downloading.

  • GEvent.addListener(...) return?

    - by user354436
    Hello, my Question is as follows: What does GEvent.addListener(map, "click" function(){...}) return into the callback function? I don't find any information in the GMaps reference at all, can you show me some? The only thing I found out was that there are two parameters, "overlay" and "latLng" that are passed. The name of these parameters should not be of interest right? I could also name them "foo" and "bar" as far as I know. But the parameter "overlay" seems to be empty anyway? Also I have problems passing these two parameters directly into a callback function I created myself which looks like that... GEvent.addListener(gmap, "click", generateMarker(overlay, latLng)); ... instead of writing the following, which actually works fine. GEvent.addListener(gmap, "click", function(overlay, latLng) { generateMarker(overlay, latLng); });

    - by iira
    I want to get the name or label of drive. I use this function : function GetVolumeLabel(DriveChar: Char): string; var NotUsed: DWORD; VolumeFlags: DWORD; VolumeInfo: array[0..MAX_PATH] of Char; VolumeSerialNumber: DWORD; Buf: array [0..MAX_PATH] of Char; begin GetVolumeInformation(PChar(DriveChar + ':\'), Buf, SizeOf(VolumeInfo), @VolumeSerialNumber, NotUsed, VolumeFlags, nil, 0); SetString(Result, Buf, StrLen(Buf)); { Set return result } Result:=AnsiUpperCase(Result) end; For example, here're my drives in Windows Explorer : Local Disk (C:) Data (D:) DVD RW Drive (E:) The output of the code : C: D: DATA E: The labels of C and E are empty. What winapi/function should I use to display the label of unnamed drive (C and E)?

  • Custom iPad keyboard backspace method last character crash

    - by isaaclimdc
    I'm making a custom UI iPad keyboard app, and I'm doing something similar to this post for the backspace method: custom backspace button crashes iPhone app However, the app will always crash when I "backspace" for the last character in the UITextView. I know -substringToIndex won't work for an empty string, but I tried using a temporary mutable string then using -deleteCharactersInRange, and that crashed it too. I'm guessing the crash is due to me manually setting the -selectedRange property for the text view after deleting a character? But even if I do: textView.selectedRange = NSMakeRange(0, 0); the app will crash. Any ideas?

  • Perl Regular expression remove double tabs, line breaks, white spaces

    - by Scoox
    Hi guys, I want to write a perl script that removes double tabs, line breaks and white spaces. What I have so far is: $txt=~s/\r//gs; $txt=~s/ +/ /gs; $txt=~s/\t+/\t/gs; $txt=~s/[\t\n]*\n/\n/gs; $txt=~s/\n+/\n/gs; But, 1. It's not beautiful. Should be possible to do that with far less regexps. 2. It just doesn't work and I really do not know why. It leaves some double tabs, white spaces and empty lines (i.e. lines with only a tab or whitespace) I could solve it with a while, but that is very slow and ugly. Any suggestions?

  • Visual Studio 2008, MSBuild: "replacement" projects

    - by liori
    Hello, My solution has a library project which needs a special environment to be built (lots of external libraries and tools)... but it is not vital to our application. We'd like to avoid installing these tools when not necessary (most of our developers work on other parts of code). We have created another project which has the same API, but has an empty implementation and is compilable without those external tools. I'd like to be able to easily switch between those projects and still get all the references in other projects correct. I don't know VS/MSBuild very well, but willing to learn whatever is necessary. Is it possible? I am looking for ideas... We're using Subversion, and solutions involving some hacks inside VCS are also welcome.

  • iPhone - Create non-persistent entities in core data

    - by ncohen
    Hi everyone, I would like to use entity objects but not store them... I read that I could create them like this: myElement = (Element *)[NSEntityDescription insertNewObjectForEntityForName:@"Element" inManagedObjectContext:managedObjectContext]; And right after that remove them: [managedObjectContext deleteObject:myElement]; then I can use my elements: myElement.property1 = @"Hello"; This works pretty well even though I think this is probably not the most optimal way to do it... Then I try to use it in my UITableView... the problem is that the object get released after the initialization. My table becomes empty when I move it! Thanks edit: I've also tried to copy the element ([myElement copy]) but I get an error...

  • mysqli query not working when variable inserted

    - by Freelancer
    Hi Everyone, I need an extra pair of eyes! I have a super-simple query: $result = $mysqli->query("SELECT post_id FROM blog_posts WHERE post_uri = 'the-test-post' LIMIT 1"); $row = $result->fetch_array(); and this gives me the post_id. However, if I insert a variable for post_uri, the result is empty. Ways I tried of which none worked: $result = $mysqli->query("SELECT post_id FROM blog_posts WHERE post_uri = '".$post_uri."' LIMIT 1"); $result = $mysqli->query("SELECT post_id FROM blog_posts WHERE post_uri = ".$post_uri." LIMIT 1"); $result = $mysqli->query("SELECT post_id FROM blog_posts WHERE post_uri = $post_uri LIMIT 1"); I have similar query on another page working just right, so that confuses me even more. Help appreciated.

  • LinkButton child controls render

    - by Alex
    Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

  • python - from matrix to dictionary in single line

    - by Sanich
    matrix is a list of lists. I've to return a dictionary of the form {i:(l1[i],l2[i],...,lm[i])} Where the key i is matched with a tuple the i'th elements from each list. Say matrix=[[1,2,3,4],[9,8,7,6],[4,8,2,6]] so the line: >>> dict([(i,tuple(matrix[k][i] for k in xrange(len(matrix)))) for i in xrange(len(matrix[0]))]) does the job pretty well and outputs: {0: (1, 9, 4), 1: (2, 8, 8), 2: (3, 7, 2), 3: (4, 6, 6)} but fails if the matrix is empty: matrix=[]. The output should be: {} How can i deal with this?

  • IE's responseXML.getElementsByTagName() unable to handle non English character ?

    - by trix
    I have a javascript that does this (http is your XMLHttpRequest object) var r = http.responseXML.getElementsByTagName('item'); The issue is variable r is always an empty list if the response contains non-English character (r.length is 0). The response header is correctly set Content-Type: text/xml;charset=ISO-8859-1 This is what the response from the webserver looks like <?xml version='1.0' encoding='UTF-8'?> <d> <r> <item value="jmob" label="John Möb"/> </r> </d> It happens only in IE (both IE6 and IE8), works in Firefox and Chrome. If items contain only English characters, it works fine. Is there a workaround for this ?

  • How to refactor this Ruby on Rails code?

    - by yuval
    I want to fetch posts based on their status, so I have this code inside my PostsController index action. It seems to be cluttering the index action, though, and I'm not sure it belongs here. How could I make it more concise and where would I move it in my application so it doesn't clutter up my index action (if that is the correct thing to do)? if params[:status].empty? status = 'active' else status = ['active', 'deleted', 'commented'].include?(params[:status]) ? params[:status] : 'active' end case status when 'active' #active posts are not marked as deleted and have no comments is_deleted = false comments_count_sign = "=" when 'deleted' #deleted posts are marked as deleted and have no comments is_deleted = true comments_count_sign = "=" when 'commented' #commented posts are not marked as deleted and do have comments is_deleted = false comments_count_sign = ">" end @posts = Post.find(:all, :conditions => ["is_deleted = ? and comments_count_sign #{comments_count_sign} 0", is_deleted])

  • HtmlUnit doesn't load externally referenced javascript

    - by nici
    I have run into a problem while trying to test a web application with HtmlUnit. Please bear in mind that I haven't used HtmlUnit very long so I might be missing something trivial. For some reason externally referenced javascripts aren't being loaded. When I print the page as xml all i get is this: <script language="javascript" src="urltofile.js"> </script> As you can see the script tag is empty when it should contain the javascript. What am I missing? I have googled for a solution all morning but haven't found any relevant information. Any help would be greatly appreciated!

  • Rails - Posting a Boolean (true or False) and updating the DB in the controller

  • How can I run a function anytime anything is animated with jQuery?

    - by WillyCornbread
    Hi - I have some jQuery animations in my code to slide divs up and down in response to some mouse clicks and other logic. This is all working just peachy, however in IE 6 some of the smaller icon images on the page don't slide along with the rest of the div for some strange reason. They kind of stay put then flicker into the new position and I've chalked this up to an IE6 'feature'. Considering that I have to support IE6, I wanted to just hide the icons anytime an animation started, and show them again when the queue was empty. I couldn't find a reference to any kind of events or hooks into the queue itself and I'd rather not add the hide code, then the show code to every animation as a callback. Thanks if you can help- b

  • What is @namespace field in C# class?

    - by MainMa
    Hi, I'm browsing the source code of StyleCop, and I found a curious thing: /// <summary> /// The namespace that the rule is contained within. /// </summary> private string @namespace; // [...] internal Rule(string name, string @namespace, string checkId, string context, bool warning) : this(name, @namespace, checkId, context, warning, string.Empty, null, true, false) { Param.Ignore(name, @namespace, checkId, context, warning); } What is this thing? Is it just a simple field where at-sign is used to indicate that it is a field, and not a namespace keyword? If so, may at-sign be used for any reserved word (for example @dynamic, @using, etc.)?
