  • how do I do this UPDATE in sqlite?

    - by Jason S
    I have a table assoc containing columns local_id, remote_id, cachedData I can successfully run an SQLITE query that looks like SELECT a1.local_id, a1.remote_id FROM assoc a1 LEFT JOIN .... so that I identify certain rows of the assoc table that meet my criteria. What I would like to do is to set cachedData to null in those rows. How can I do this? Sqlite doesn't support UPDATE with joins; you can issue subqueries but I can't figure out how to get the syntax correct; it seems nonintuitive to me.

  • Get/Set nested property values

    - by Daniel Deer
    I'll try to be more descriptive here. A Few Q's: using: var foo = new Foo() { Bar = new Bar() { Value = "Value" } }; var value = DataBinder.Eval(foo, "Bar.Value"); Or: This one It is possible to retrieve an internal nested property using property path syntax. Is there a way to set/trigger a nested property (a regular property not DependencyProperty) easily with some kind of simple mechanisms as described here? I want to acheive something like: string newValue = "Hello World!"; DataBinder.EvalSet(foo, "Bar.Value", NewValue); Is there any mechanism that support both property path (for nested objects) and XPATHs (if the objects are XPATH navigable of course) ? again, that supports get and set options. Thanks, DD

  • WCF host address question

    - by Estelle
    when I setup the wcf service on a web server, I set the end point address as <endpoint address="http://www.mydomin.com/clientname/happy.svc" binding="basicHttpBinding" name="happysvcbasic" contract="happysvc.Ihappysvc"> </endpoint> but when type in above address on a browser, I get a different host name, which is the internal server name, such as, To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://internalservername.domain/clientname/happy.svc?wsdl I tried to add the host/baseaddress tag, but make no difference, what I missed? thanks for help.

  • [WordPress] Need help with remove_action()

    - by gabriel
    I'm trying to remove the unsightly embedded <STYLE> tag the built-in Recent Comments widget puts in my <HEAD>, but I can't seem to get the syntax right. It originally calls add_action( 'wp_head', array(&$this, 'recent_comments_style') ); to add it (in wp-includes/default-widgets.php, line 609), and I'm trying to undo it. I think it should be something like this: remove_action('wp_head', 'WP_Widget_Recent_Comments::recent_comments_style'); but with all the variations I've tried I still can't get it right. Does anyone know how to achieve this? Possibly Helpful: Function Reference: remove_action

  • Can I use string concatenation to define a class CONST in PHP?

    - by selfsimilar
    I know that you can create global constants in terms of each other using string concatenation: define('FOO', 'foo'); define('BAR', FOO.'bar'); echo BAR; will print 'foobar'. However, I'm getting an error trying to do the same using class constants. class foobar { const foo = 'foo'; const foo2 = self::foo; const bar = self::foo.'bar'; } foo2 is defined without issue, but declaring const bar will error out Parse error: syntax error, unexpected '.', expecting ',' or ';' I've also tried using functions like sprintf() but it doesn't like the left paren any more than the string concatenator '.'. So is there any way to create class constants in terms of each other in anything more than a trivial set case like foo2?

  • Getting started with C++ ( the paradigm shift from Python )

    - by orokusaki
    I want to learn C++ so that i can develop C++ Python modules for server-related stuff. I'm a purely dynamic languages developer (Python, PHP, Ruby, etc). I want to learn a fast language, and if I'm going to do this, I'd rather learn a really fast language like C++. Before I even get started though, I understand that suddenly working with static types, a different syntax, and compiling code will be quite the paradigm shift. Is there any advice that a C++ dev who also has dynamic languages experience can give me to me to help me make that shift faster?

  • Is a full list returned first and then filtered when using linq to sql to filter data from a databas

    - by RJ
    This is probably a very simple question that I am working through in an MVC project. Here's an example of what I am talking about. I have an rdml file linked to a database with a table called Users that has 500,000 rows. But I only want to find the Users who were entered on 5/7/2010. So let's say I do this in my UserRepository: from u in db.GetUsers() where u.CreatedDate = "5/7/2010" select u (doing this from memory so don't kill me if my syntax is a little off, it's the concept I am looking for) Does this statement first return all 500,000 rows and then filter it or does it only bring back the filtered list?

  • How to Print the contents of a textbox in C++/CLI?

    - by Smoka
    I'm still learning C++ coding. I'm having troubles getting say ResultsBox-Text to printer successfully. What is the proper way to print in C++/CLI? I think im missing something simple. Ive tried multiple different routes/syntax's that ive read online/ in books. All of which got me to a dead end. Please even a rundown on the method of printing in any C based language might point me the right way. Thank you.

  • Writing .NET in dynamic language?

    - by tillda
    I'm confused by the possibility of writing .NET in dynamic languages, such as (Iron)Ruby. Particularly, I've seen code in IronRuby that used generics (...foo[String]), but I'm not aware of this feature in Ruby as it seems nonsense to me in dynamic languages. So, when I write .NET app in IronRuby, how is it with type safety and compilation? I thought that it is just as dynamic as Ruby everywhere else. I thought that if the Ruby syntax is OK all the type checking would be done at the runtime. Also, as far as I know, .NET itself is type-oriented - there are classes that heavily utilize the mentioned generics. How is this handled? And what about delegates? In dynamic languages I can have almost function-spaghetti and sometimes, its just fine (like hacking UI in javascript). Or do I have to care even about generic delegates?

  • Is file_get_contents multi line?

    - by Abs
    Hello all, Does file_get_contents maintain line breaks? I thought it did but I have tried this: if($conn){ $tsql = file_get_contents('scripts/CreateTables/SLR05_MATCH_CREATETABLES.sql'); $row = sqlsrv_query($conn, $tsql); print_r(sqlsrv_errors()); } The errors I get is that SQL Server complains that there is incorrect syntax. I get the same errors when I run the SQL Script without any line breaks, which suggests file_get_contents removes them? When I run the script normally (open the file in SQL Server Management Studio) and execute it, it works perfectly. So is there something that I can use that maintains line breaks etc? Or is there another problem here in using queries from a file with the SQL Server PHP Driver from Microsoft? Thanks all for any help

  • Centering images php

    - by peak
    I'm trying to center an image in php. I'm currently using this line of code echo '<img src="newimage.jpg" width="110" height="120" class="centre">'; However, this seems to have no effect. I've also tried using something like this, img.center { display: block; margin-left: auto; margin-right: auto; } <img src="newimage.jpg" alt="Suni" class="center" /> but this merely gives me a syntax error, how do I go about fixing this? Thanks

  • Python - Is it possible to get the name of the chained function?

    - by user1326876
    I'm working on a class that basically allows for method chaining, for setting some attrbutes for different dictionaries stored. The syntax is as follows: d = Test() d.connect().setAttrbutes(Message=Blah, Circle=True, Key=True) But there can also be other instances, so, for example: d = Test() d.initialise().setAttrbutes(Message=Blah) Now I believe that I can overwrite the "setattrbutes" function; I just don't want to create a function for each of the dictionary. Instead I want to capture the name of the previous chained function. So in the example above I would then be given "connect" and "initialise" so I know which dictionary to store these inside. I hope this makes sense. Any ideas would be greatly appreciated :)

  • What could possibly cause this error(when declaring an object inside a class) ? //noobie question

    - by M4design
    I'm battling with this assignment :) I've got two classes: Ocean and Grid. When I declare an object of the Grid inside the Ocean: unsigned int sharkCount; Grid grid; The compiler/complainer says: error C2146: syntax error : missing ';' before identifier 'grid' Can you possibly predict what produces this error with the limited info' I provided? It seems that as if the Ocean doesn't like the Grid class. Could this be because of the poor implementation of the grid class. BTW the Grid has a default constructor. Yet the error happens in compiling time!. Thanks. EDIT: They're each in separate header file, and I've included the Grid.h in the Ocean.h.

  • jQuery broken function after added new function

    - by Kyle Sevenoaks
    What's wrong here? The alert function was working until I added this new function to it. Is there anything I am doing wrong? It just simply doesn't fire the alert anymore. <input value="1" type="checkbox" name="salgsvilkar" id="checkbox2" style="float:left;" /> {literal} <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(function() { //checkbox $("#scrollwrap").click(function(){ $("#scrollwrap").toggleClass('highlight'); });? }); $(function(){ //button $("#fullfor_btn").click(function(e){ if(!$("#checkbox2").is(':checked') == false) { alert("Please accept the terms of sale."); e.preventDefault(); } }); }); </script> {/literal} <button type="submit" class="submit" name="{$method}" id="fullfor_btn" title="Fullfør bestillingen nå" value="">&nbsp;</button>

  • When (and why) is {} undefined in a JavaScript console?

    - by JS_Riddler
    In the console of both FF and Chrome, {} is considered undefined until explicitly evaluated: {}; // undefined ({}); // ? Object Actually, it's a bit less defined than undefined -- it's apparently bad syntax: {} === undefined; // SyntaxError: Unexpected token === {}.constructor; // SyntaxError: Unexpected token . But not if it's on the other side, in which case it's fine: "[object Object]" == {}.toString(); // true Or if it's not the first expression: undefined + undefined; // NaN {} + undefined; // NaN undefined + {}; // "undefined[object Object]" What gives?

  • Transitioning from C++ to C#

    - by Jim
    I am very experienced in C and C++ but am having problems finding current opportunities. I decided to switch to C# but noticed that while the syntax is very similar, the programming styles are very different (we don't have IEnumerable etc in C). So the problem I am having now is having 20 years of experience but is only a junior when it comes to interviewing for a C# job. Most of the problems are me not being able to answer questions like 1) How do you do XYZ in Sql Server? 2) What's the use of in Spring.NET In other words, the phone interviewers don;t care if you know DB programming or not - they want to know if you know SQL Server. I am frustrated because the guys who are doing the interviews seem to be so narrow sighted in knowing ONLY C#, .NET and SQL Server, that I don't know how to get past them.

  • Should I pass the BrainBench Design patterns certification?

    - by Fedyashev Nikita
    I have found Design patterns certification at the Brainbehch. I have heard from people who passed it, that there are many Language-specific patterns questions, mostly from Java and C++. I think that this certification can: force me to improve my skills on Object oriented design and design patterns; improve and structure my knowledge of the domain; give real estimate of my knowledge, which is useful issue itself The only confusion I have about this certification, is that I have to learn C++/Java language specific design patterns, while I mostly do PHP development and don't want to switch to C++/Java. I'm familiar with Java & C++ syntax, read lots of books about different subjects with code snippets in this programming languages. I think, that if I pass well all concepts except language specific patterns at certification, it won't be very good, because this concepts will gain quite low results. What would you recommend in this particular circumstance?

  • Can you pass parameters for OnAction in MS Project VBA?

    - by Anne Schuessler
    The way I can define a method to be executed with OnAction in VBA with Microsoft Project is as follows (and works correctly): .OnAction = "Macro ""DoSomething""" ... where DoSomething is the method to execute. I would like to pass a parameter to that method but can't find a way to pass it with this syntax. Does anybody have an idea how to do this? I'm getting the feeling that this is an impossible task, but maybe there's some VBA secret I'm not aware of. Please note that VBA in MS Project seems to have its quirks and is slightly different than VBA for Excel or Access. This seems to be the case for the OnAction property which needs the extra Macro keyword to work correctly. If I'm wrong here please enlighten me.

  • Function return type style

    - by JB
    I'm learning c++0x, at least the parts supported by the Visual C++ Express 2010 Beta. This is a question about style rather than how it works. Perhaps it's too early for style and good practice to have evolved yet for a standard that isn't even released yet... In c++0x you can define the return type of a method using - type at the end of the function instead of putting the type at the start. I believe this change in syntax is required due to lambdas and some use cases of the new decltype keyword, but you can use it anywhere as far as I know. // Old style int add1(int a, int b) { return a + b; } // New style return type auto add2(int a, int b) -> int { return a + b; } My question really then, is given that some functions will need to be defined in the new way is it considered good style to define all functions in this way for consistency? Or should I stick to only using it when necessary?

  • Why Are Ruby Programmers So Full of Themselves? [closed]

    - by Pierreten
    I've noticed this culture surrounding Ruby where developers truly believe that they are somehow more gifted than developers of other languages, regardless of experience and talent (even when that isn't the case, I've met some extremely junior Ruby developers come up with some pretty basic constructs, and pass them off as some sort of revolutionary idea). The derision of strongly typed languages seems to be a common theme as well; regardless of its merits. Is there something particular to the Ruby syntax in general that is to account for this? Is there a socialogical component to it?

  • Cakephp, Retreive Data for HABTM Models using conditional find

    - by ion
    There are 2 Models: Project & Category that are bind with HABTM relationship. I would like to perform a search from projects controller that can do the following: FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised' Apologies for the syntax, I'm no sequel expert. What I have managed to do is to retrieve all projects that do not belong to Category uncategorised into an array however I'm not sure as to how to search again the array result for DISTINCT Project.schedule values (needed to fill out a form drop down) I hope I made myself clear.

  • VB.NET logical expression evaluator

    - by Tim
    I need to test a logical expression held in a string to see if it evaluate to TRUE or FALSE.(the strig is built dynamically) For example the resulting string may contain "'dog'<'cat' OR (14 AND 4<6)". There are no variables in the string, it will logically evaluate. It will only contain simple operators = < < = <= and AND , OR and Open and Close Brackets, string constants and numbers. (converted to correct syntax && || etc.) I currently acheive this by creating a jscipt function and compiling it into a .dll. I then reference the .dll in my VB.NET project. class ExpressionEvaluator { function Evaluate(Expression : String) { return eval(Expression); } } Is there a simpler method using built in .NET functions or Lamdba expressions.
