  • Matching of tuples

    - by Jack
    From what I understood I can use pattern-matching in a match ... with expression with tuples of values, so something like match b with ("<", val) -> if v < val then true else false | ("<=", val) -> if v <= val then true else false should be correct but it gives me a syntax error as if the parenthesis couldn't be used: File "ocaml.ml", line 41, characters 14-17: Error: Syntax error: ')' expected File "ocaml.ml", line 41, characters 8-9: Error: This '(' might be unmatched referring on first match clause.. Apart from that, can I avoid matching strings and applying comparisons using a sort of eval of the string? Or using directly the comparison operator as the first element of the tuple?

  • XmlTextWriter.WriteFullEndElement tags on the same line

    - by Apeksha
    I am using an XMLTextWriter to create an XML document dynamically (in VB.Net). I want empty tags to appear like this - <Tag></Tag> and not this - <Tag /> So, I am using WriteFullEndElement to end the element tag. But it is writing out the tag as - <Tag> </Tag> i.e. with a newline character between the tags. The web service reading this XML rejects it due to the newline character. How do I avoid the newline, and have both the start and end tags on the same line?

  • How to get rid of this w3 validation error?

    - by Pandiya Chendur
    I developed a web page and now i am validating it with w3c HTML4.0... I got one error it says Error Line 30, Column 57: there is no attribute "DATA-FLEXMENU" href="about.php" class="mainlink" data-flexmenu="flexmenu1">About Us</a></div> You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead). Any ways of getting rid of this error .... Any suggestion...

  • iPhone / NSArray : How do I format a text file to be read in using arrayWithContentsOfFile

    - by nickthedude
    I have several large word lists and I had been loading them in place in the code as follows: NSArray *dict3 = [[NSArray alloc] initWithObjects:@"abled",@"about",@"above",@"absurd",@"absurdity", ... but now it is actually causing an exc_bad_access error weirdly, i know it seems implausible but for some reason IT IS causing it. (trust me on this I just spend the better part of a day debugging this crap) Anyway, I'm looking to get these humongous lines of code out of my files but I'm not sure what the best approach is. I guess I could do a plist but I need to figure out how to automate the process. it be easiest if I could just use the text files I've been compiling so if anyone knows how I can format the text file so that the myArray = [NSArray arrayWithContentsOfFile: @"myTextFile.txt"]; will be read in correctly as one word per element in the array it would really be appreciated. Thanks, Nick

  • About enumerations in Delphi and c++ in 64-bit environments

    - by sum1stolemyname
    I recently had to work around the different default sizes used for enumerations in Delphi and c++ since i have to use a c++ dll from a delphi application. On function call returns an array of structs (or records in delphi), the first element of which is an enum. To make this work, I use packed records (or aligned(1)-structs). However, since delphi selects the size of an enum-variable dynamically by default and uses the smallest datatype possible (it was a byte in my case), but C++ uses an int for enums, my data was not interpreted correctly. Delphi offers a compiler switch to work around this, so the declaration of the enum becomes {$Z4} TTypeofLight = ( V3d_AMBIENT, V3d_DIRECTIONAL, V3d_POSITIONAL, V3d_SPOT ); {$Z1} My Questions are: What will become of my structs when they are compiled on/for a 64-bit environment? Does the default c++ integer grow to 8 Bytes? Are there other memory alignment / data type size modifications (other than pointers)?

  • Getting the first image elements id within an unordered list using JQuery

    - by Roland
    I'm trying to get the id of the first element of an unordered list using JQuery. Here's the list <ul class="list"> <li><img id="1" src="image1.jpg" name="image1" /></li> <li><img id="2" src="image2.jpg" name="image2" /></li> <li><img id="3" src="image3.jpg" name="image3" /></li> <li><img id="4" src="image4.jpg" name="image4" /></li> <li><img id="5" src="image5.jpg" name="image5" /></li> </ul> JQuery var id = $('.list li img'):first.attr('id');

  • .NET and XML: How can I read nested namespaces (<abc:xyz:name attr="value"/>)?

    - by Entrase
    Suppose there is an element in XML data: <abc:xyz:name attr="value"/> I'm trying to read it with XmlReader. The problem is that I get XmlException that says The ‘:’ character, hexadecimal value 0x3A, cannot be included in a name I have already declared "abc" namespace. I have also tried adding "abc:xyz" and "xyz" namespaces. But this doesn't help at all. I could replace some text before parsing but there may be some more elegant solution. So what should I do? Here is my code: XmlReaderSettings settings = new XmlReaderSettings() NameTable nt = new NameTable(); XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt); nsmgr.AddNamespace("abc", ""); nsmgr.AddNamespace("xyz", ""); XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None); // So this reader can't read <abc:xyz:name attr="value"/> XmlReader reader = XmlReader.Create(path, settings, context);“

  • <transport> tag within the ServicesReferences.ClientConfig

    - by jdiaz
    I've created a WCF service and added it to an existing Silverlight application that I am working on. When I run the silverlight application in debug mode it fails when I reference the WCF web service. Unrecognized element '' in service reference configuration. Note that only a subset of the Windows Communication Foundation configuration functionality is available in Silverlight. After searching around apparently the following line is causing the app to fail: <transport> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> After removing the above lines everything works. What is the issue here? Should I believing this code in and configuring something else?

  • Can I create a collection in Scala that uses different equals/hashCode/compare implementations?

    - by Willis Blackburn
    I'm looking for as simple way to create an identity set. I just want to be able to keep track of whether or not I've "seen" a particular object while traversing a graph. I can't use a regular Set because Set uses "==" (the equals method in Scala) to compare elements. What I want is a Set that uses "eq." Is there any way to create a Set in Scala that uses some application-specified method for testing equality rather than calling equals on the set elements? I looked for some kind of "wrapEquals" method that I could override but did not find it. I know that I could use Java's IdentityHashMap, but I'm looking for something more general-purpose. Another idea I had was to just wrap each set element in another object that implements equals in terms of eq, but it's wasteful to generate tons of new objects just to get a new equals implementation. Thanks!

  • Binding expression failing.

    - by Rohit Kandhal
    My output window is flooded with binding expression failures like : "Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=DataContext.CurrentActivationObjectType; DataItem=null; target element is 'StackPanel' (Name=''); target property is 'NoTarget' (type 'Object')" and similar binding issues. Also i found that these failure occurs only when the screen loads (i.e. first time) No failures there after. I've checked the binding it is fine . Binding :

  • Supervising multiple gen_servers with same module / different arguments

    - by Justin
    Hi, I have a OTP application comprising a single supervisor supervising a small number of gen_servers. A typical child specification is as follows: {my_server, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server]} No problems so far. I now want to an add extra gen_server to the supervisor structure, using the same module Module/Fn as above, but different arguments, eg {my_server_2, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server_2]} I thought this would work, but no: =SUPERVISOR REPORT==== 15-Apr-2010::16:50:13 === Supervisor: {local,my_sup} Context: start_error Reason: {already_started,<0.179.0>} Offender: [{pid,undefined}, {name,my_server_2}, {mfa,{my_server,start_link,[]}}, {restart_type,permanent}, {shutdown,5000}, {child_type,worker}] Do the module arguments in the second element of each child specification need to be different ? Thanks, Justin

  • How do I visualize a complex graph in .Net?

    - by Ivan
    I need to visualize a graph (technically being a set of Entity Framework objects, but I can translate it to another representation if needed) of this kind. I don't know how to name it (by the way, if you know - I'll appreciate if you tell me). It would be ideal for graph elements to be clickable (so that when user clicks on a block, I can handle an event with the element id specified) but I can survive even without any interactivity. Are there any components available good for this task? If no, what should I look for to help me to develop an algorithm for drawing such a graph with visually-comfortable layout?

  • [Simple] Beginner AJAX script not working, stuck on opening XMLHttpRequest

    - by Julian H. Lam
    Hopefully, this question isn't too juvenile to ask - but here goes: I'm trying to learn AJAX, and I'm stuck on a simple content-fetch. Here is my code: request = getHTTPObject(); function useHttpResponse() { if (request.readyState == 4) { document.getElementById("p").innerHTML = request.responseText; } } function update_p() { request.open("GET",content.html,true); request.onreadystatechange = useHttpResponse; } getHTTPObject is correctly defined, and returns a proper XMLHttpObject. As you probably guessed from the excerpt, the element I am trying to update is id'd "p". It calls the script correctly when a button is clicked, no problem there. The script seems to stop at line 8, at request.open. There's no error, and the script silently ignores anything afterward. I don't think I've missed anything, but of course, I probably did. Where did I go wrong? Thanks!

  • Custom app.config section with a simple list of "add" elements

    - by Joe
    How do I create a custom app.config section that is just a simple list of add elements? I have found a few examples (e.g. http://stackoverflow.com/questions/1316058) for custom sections that look like this: <RegisterCompanies> <Companies> <Company name="Tata Motors" code="Tata"/> <Company name="Honda Motors" code="Honda"/> </Companies> </RegisterCompanies> But how do I avoid the extra collection element ("Companies") so that it looks the same as the appSettings and connectionStrings sections? In other words, I'd like: <registerCompanies> <add name="Tata Motors" code="Tata"/> <add name="Honda Motors" code="Honda"/> </registerCompanies>

  • How should it work if I want a page to have a theme-roller (more or less like the jQuery themeroller

    - by DanC
    The basic idea is to create a page that gives the user the ability to choose a skin or theme from a menu. When the user selects the desired skin/theme, it should be applied to the page, just like the jquery ui theme roller page. So, to be more precise, what I am trying to know is how to apply dynamically the style to a page - how to load the css and so forth. On the jquery ui theme roller, is there any javascript triggered after the new set of styles is loaded? (for js positioning or sizing?) (The answer may be simple as "just create a new style element and set its src"...) Just to be clear, I don't need the option to let users customize the UI, I want them just to be able to pick from a few pre set styles. Thanks!

  • FF extension: displaying an array of string elements in a sidebar

    - by sujay-jain
    I am developing a ff extension which displays a list of elements from an array (dynamic) in the sidebar. The array is dynamic and needs to be constructed in a function everytime the sidebar is opened (or any other event handler). Later, i will need to implement link functionality on parts of the string. What is the best way to go about this? I have created an empty sidebar and just know the label element as of now. menu, and menuitem dont work. What other elements can i use to display text in a good way which supports dynamic contruction. Is there some good tutorial/sample extension which i can see and learn?

  • Flex - weird display behavior on large number of Canvas

    - by itarato
    Hi, I have a Flex app (SDK 3.5 - FP10) that does mindmap trees. Every node is a Canvas (I'm using Canvas specific properties so I needed it). It has a shadow effect, background color and some small ui element on it (like icons, texts...). It works perfectly until it goes over ~700 nodes (Canvas). Over that number it shows grey rectangles: http://yfrog.com/bhw2pj . If I turn off the DropShadowFilter effect for the Canvas, they are also gone, so I assume it's a DropShadowFilter problem: http://yfrog.com/2d9y8j . The effect is simple: private static var _nodeDropShadow:DropShadowFilter = new DropShadowFilter(1, 45, 0x888888, 1, 1, 1); _backgroundComp.filters = _nodeDropShadow; Is it possible that Flex can't handle that much? Thanks in advance

  • Change background colour of individual elements on the fly

    - by John
    Hi, Is there a way in CSS or JQuery where I can dynamically change the background of li tags so they get slightly lighter for each element until it gets to white. For example say I had a list of 10 li elements. The first would have a red (#ff0000) background, the next one would then be a lighter shade of red, and so on and so on until we got to the last one which would have a background of white (#FFFFFF) The list can be any length and i just want the background colour to go from one colour e.g. red to another colour e.g. white. My site uses JQuery so if I have to use that I don't mind. Thanks

  • Close a tag with no text in lxml

    - by PulpFiction
    I am trying to output a XML file using Python and lxml However, I notice one thing that if a tag has no text, it does not close itself. An example of this would be: root = etree.Element('document') rootTree = etree.ElementTree(root) firstChild = etree.SubElement(root, 'test') The output of this is: <document> <test/> </document I want the output to be: <document> <test> </test> </document> So basically I want to close a tag which has no text, but is used to the attribute value. How do I do that? And also, what is such a tag called? I would have Googled it, but I don't know how to search for it.

  • Creating an array & outputting its code definition for preloading

    - by user422318
    I want to create a 2d array that represents my 2d canvas. For each pixel, I will look up the value and then save an integer {0, 1, 2, 3, 4} as each element of the array. Unfortunately, this takes way too friggin' long to run each time I load the game. How can I write a script that creates this array for me and outputs the array code so I can just paste it in a js file and have it preloaded? (I'm prototyping a game, so I just need to run this for my test map or two.)

  • In an Android test, how to check that a View is shown?

    - by Jan Zankowski
    Hello, I'm writing a UI test case (using ActivityUnitTestCase) and would like to check if at a given time a View subclass is visible to the user. I've found the View#isShown() method, which claims to do exactly this - checking the visibility field of this element and all its parents - but somehow it always returns "false" for all the elements. I'll be grateful for some help. If it makes it easier, I can paste some code. Also, I found ViewAsserts#assertOnScreen(View origin, View view) but it doesn't seem to do the right thing either - always returns true. Am I perhaps calling it wrong: assertOnScreen(viewImTesting.getRootView(), viewImTesting)? Thanks, Jan
