  • What hash/map based programming language exist?

    - by Davorak
    Much like lisp is often considered a list based programming language what languages are considered map based? I remember reading about one a few years back, but can not longer find a reference to it. It looked something like: [if:test then:<code> else:<more code>] edit: and more where quoted code blocks which would be conditional evaluated. In this fashion if/cond and others would not be special form as they are in lisp/scheme.

  • Elegant way to search for UTF-8 files with BOM?

    - by vog
    For debugging purposes, I need to recursively search a directory for all files which start with a UTF-8 byte order mark (BOM). My current solution is a simple shell script: find -type f | while read file do if [ "`head -c 3 -- "$file"`" == $'\xef\xbb\xbf' ] then echo "found BOM in: $file" fi done Or, if you prefer short, unreadable one-liners: find -type f|while read file;do [ "`head -c3 -- "$file"`" == $'\xef\xbb\xbf' ] && echo "found BOM in: $file";done It doesn't work with filenames that contain a line break, but such files are not to be expected anyway. Is there any shorter or more elegant solution? Are there any interesting text editors or macros for text editors?

  • Should I share UI for objects that use common fields?

    - by wb
    I have a parent class that holds all of the fields that are common between all device types. From that, I have a few derived classes that each hold their unique fields. Say I have device type "Switch" and "Transformer". Both derived classes only have 2-3 of their own unique fields. When doing the UI design (windows forms) in this case. Should I create two separate forms for each device type or create a user control with all fields that are shared among all devices? Thank you.

  • What is wrong with the below statement(C#3.0 / Lambda)

    - by Newbie
    what is wrong in the below Enumerable.Range(0, objEntityCode.Count - 1).Select(i => { options.Attributes[i] = new EntityCodeKey { EntityCode = objEntityCode[i].EntityCodes , OrganizationCode = Constants.ORGANIZATION_CODE }; }) .ToArray(); Throwing error The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. But this works Enumerable.Range(0, objEntityCode.Count - 1).ToList().ForEach(i => { options.Attributes[i] = new EntityCodeKey { EntityCode = objEntityCode[i].EntityCodes , OrganizationCode = Constants.ORGANIZATION_CODE }; } ); Using C#3.0. Purpose: I am learning LINQ / LAMBDA and trying to do the same program in different way. Thanks.

  • referencing desired objects in namespaced functions

    - by RyOnLife
    I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?

  • jQuery 1.4.2 - is $("#foo").hide("normal") broken or am I crazy?

    - by karim79
    Hi all, Does anyone know why .hide("normal") does not seem to be working in jQuery 1.4.2? Is it a bug, has it been removed or am I just crazy? I've managed to duplicate this using several different scenarios. Just try this: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $("button").click(function() { $("div.text").hide("normal"); }); </script> <div class="test">Hello this is a test</div> <button>Click</button>

  • cant get ajax response (JSON) to call 'success' function?

    - by Haroldo
    for some reason the success function isnt being called? javscript: $.ajax({ type: 'POST', url: 'http://localhost/hf_latest_desktop/st_pages/user_area/acc_buttons/pass_change/pass_change_ajax.php', data: data, dataType: 'json', success: function(e){ console.log(e); if(e.status == 'success'){ alert('your password has been changed!'); } if(e.status == 'error1'){ alert('please fill in all inputs!'); } if(e.status == 'error2'){ alert('password incorrect!'); } if(e.status == 'error3'){ alert('change failed!'); } } }); php file ajax is calling to: <?php session_start(); session_cache_limiter('nocache'); header('Expires: ' . gmdate('r', 0)); header('Content-type: application/json'); $status = 'error1'; //for sake of example ?> {'status':'<?php echo $status; ?>'}

  • Add 64 bit offset to a pointer

    - by Novox
    In F#, there's the NativePtr module, but it seems to only support 32 bit offsets for its’ add/get/set functions, just like System.IntPtr does. Is there a way to add a 64 bit offset to a native pointer (nativeptr<'a) in F#? Of course I could convert all addresses to 64 bit integers, do normal integer operations and then convert the result again to nativeptr<'a, but this would cost additional add and imul instructions. I really want the AGUs to perform the address calculations. For instance, using unsafe in C# you could do something like void* ptr = Marshal.AllocHGlobal(...).ToPointer(); int64 offset = ...; T* newAddr = (T*)ptr + offset; // T has to be an unmanaged type Well actually you can't, because there is no "unmanaged" constraint for type parameters, but at least you can do general pointer arithmetic in a non-generic way. In F# we finally got the unmanaged constraint; but how do I do the pointer arithmetic?

  • Hibernate and mssql inner join rowcount

    - by ez2sarang
    I am struggling with Hibernate Criteria. My aim is to create the following request using Hibernate Criteria : select count(*) as y0_ from PInterface this_ inner join Product product2_ on this_.product_id=product2_.id where this_.product_interface_type_id=? Here is my code: @Entity @Table(name = "PInterface") public class PInterface { @Id @GeneratedValue @Column(name = "id", nullable = false, insertable = false, updatable = false) private int id; @Column(name = "product_id") private int productId; @Column(name = "product_interface_type_id") private int type; @ManyToOne(optional=false) @JoinColumn(name = "product_id", referencedColumnName = "id", insertable=false, updatable=false) private Product product; } @Entity @Table(name = "Product") public class Product { @Id @GeneratedValue @Column(name = "id", nullable = false, insertable = false, updatable = false) private int id; private String name; } //Criteria is : Object criteria = sessionFactory.getCurrentSession() .createCriteria(PInterface.class) .add(Restrictions.eq("type", 1)) .setProjection(Projections.rowCount()) .uniqueResult() ; However, the results ... select count(*) as y0_ from PInterface this_ where this_.product_interface_type_id=? Where Inner join? Thank you for help!

  • jQuery .noconflict with prototype not working in (you guessed it) IE.

    - by Kyle Sevenoaks
    On my new customer page, I have successfully implemented a jQuery show/hide toggle alongside a Prototype script using jQuery's .noconflict. (Thanks to all for answers!) But as the world of the net is, IE's not playing ball. {literal} <script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"> </script> <script type="text/javascript"> var $j = jQuery.noConflict(); $j(function() { $j("#button1").click(function() { $j("#show-hide").toggle("slow"); }); });? </script> {/literal} As you all must know by now, I'm just newly coming to all this jQuery stuff, so I have no idea what could cause it. Thanks for any help.

  • Do you have to call .Save() when modifying a application setting that is bound to a control property

    - by Jordan S
    I am programming in .NET I have an application setting of type string. On my form I have a textbox. I bound the text property of the textbox to my application setting. If I type something in the textbox it changes the value that is held in the Application setting but the next time I start the program it goes back to the default value. Do I need to call Properties.Settings.Default.Save(); after the text is entered for the new value to be saved? Shouldn't it do this automatically? Is there a way I can make it do it automatically?

  • FLEX, Actionscript: how can I invoke a CustomEvent ?

    - by Patrick
    hi, I've created a custom MouseEvent in Flex: package { import flash.events.MouseEvent; public class CustomMouseEvent extends MouseEvent { public var tags:Array = new Array(); public function CustomMouseEvent(type:String, tags:Array) { super(type, true); this.tags = tags; } } } Now I would like to understand how to pass the parameter tags from both Actionscript and MXML: From actionscript I'm trying something like this, but it doesn't work: newTag.addEventListener(MouseEvent.MOUSE_UP, dispatchEvent(new CustomMouseEvent(MouseEvent.MOUSE_UP,[newTag.name]))); From MXML i'm doing this and it doesn't work as well: <mx:LinkButton click="dispatchEvent(new CustomMouseEvent(MouseEvent.MOUSE_UP, bookmarksRepeater.currentItem.tags))" /> thanks

  • Linq to SQL DateTime values are local (Kind=Unspecified) - How do I make it UTC?

    - by ericsson007
    Isn't there a (simple) way to tell Linq To SQL classes that a particular DateTime property should be considered as UTC (i.e. having the Kind property of the DateTime type to be Utc by default), or is there a 'clean' workaround? The time zone on my app-server is not the same as the SQL 2005 Server (cannot change any), and none is UTC. When I persist a property of type DateTime to the dB I use the UTC value (so the value in the db column is UTC), but when I read the values back (using Linq To SQL) I get the .Kind property of the DateTime value to be 'Unspecified'. The problem is that when I 'convert' it to UTC it is 4 hours off. This also means that when it is serialized it it ends up on the client side with a 4 hour wrong offset (since it is serialized using the UTC).
