  • return from a linq where statement

    - by Vaccano
    I have the following link function MyLinqToSQLTable.Where(x => x.objectID == paramObjectID).ToList(); I most of the time you can change a linq call to be several lines by adding curly brackets around the method body. Like this: MyLinqToSQLTable.Where(x => { x.objectID == paramObjectID; }).ToList(); Problem is the implied return that was there when I just did a Boolean compare is now not done. Return (x.objectID == paramObjectID); is not accepted either. How do do this? can I do this? NOTE: I know that I can add another where clause if needed. But I would still like to know the answer to this.

  • Changing the cursor in asp.net

    - by Bob Avallone
    I want to change the cursor to an hourglass in my asp.net application to let my users know that the process is running. I searched for an answer and was advised to use javascript as follows. 1) Add this javascript function hourglass() { document.body.style.cursor = "wait"; } 2) then in my code in the page load event: btnImport.Attributes.Add("onclick", "javascript: hourglass();"); When btnImport is the button they click on However this does not work. But if I add an alert to the hourglass function. it does work. Is there some way to get this to work without the alert. Thanks in advance. Bob Avallone

  • "Forked Java VM exited abnormally" error from junit tests

    - by Alb
    I have a java junit test that passes when run alone on a development machine. We also have a hudson job which runs all the tests, invoked via ant, on a Mac OS X 10.4 node with Java 1.5. The test was passing in the hudson build until recently but now (with no related code changes) one test fails everytime with the following error: Error Message Forked Java VM exited abnormally. Please note the time in the report does not reflect the time until the VM exit. Stacktrace junit.framework.AssertionFailedError: Forked Java VM exited abnormally. Please note the time in the report does not reflect the time until the VM exit. googling shows many others seem to have run into the same problem but there I couldn't find any answer.

  • Convert XML attributes to a Dictionary in Linq to XML

    - by NateD
    I've got a program that needs to convert two attributes of a particular tag to the key and value of an Dictionary<int,string>. The XML looks like this: (fragment) <startingPoint coordinates="1,1" player="1" /> and so far my LINQ looks something like this: XNamespace ns = "http://the_namespace"; var startingpoints = from sp in xml.Elements(ns+"startingPoint") from el in sp.Attributes() select el.Value; Which gets me a nice IEnumerable full of things like "1,1" and "1", but there should be a way to adapt something like this answer to do attributes instead of elements. Little help please? Thank you!

  • How to decode Google spreadsheet's Json respose as a Php Array

    - by Mohammad
    My google Docs Spreadsheet call returns this response in the json format (I only need everything after "rows") please look at the formatted response here : ) I use php's json_decode function to parse the data and use it (Yes, I am awful at php) This code returns NULL, and according to the documentation, NULL is returned "if the json cannot be decoded". $json = file_get_contents($jsonurl); $json_output = json_decode($json); var_dump ($json_output); // Returns NULL Basically, what i want to accomplish is to make a simple array from the first row values of the Json response. like this $array = {'john','John Handcock','[email protected]','2929292','blanc'} You guys are genius, I would appreciate your insight and help on this very much! Answer as "sberry2A" mentions bellow, the response is not valid Json, google offers the Zend Json library for this purpose, tho I decided to parse the tsv-excel version instead :)

  • C++: Dependency injection, circular dependency and callbacks

    - by Jonathan
    Consider the (highly simplified) following case: class Dispatcher { public: receive() {/*implementation*/}; // callback } class CommInterface { public: send() = 0; // call } class CommA : public CommInterface { public: send() {/*implementation*/}; } Various classes in the system send messages via the dispatcher. The dispatcher uses a comm to send. Once an answer is returned, the comm relays it back to the dispatcher which dispatches it back to the appropriate original sender. Comm is polymorphic and which implementation to choose can be read from a settings file. Dispatcher has a dependency on the comm in order to send. Comm has a dependency on dispatcher in order to callback. Therefor there's a circular dependency here and I can't seem to implement the dependency injection principle (even after encountering this nice blog post).

  • How do I use test/beta Perl modules from test Perl scripts?

    - by DVK
    If my Perl code has a production code location and "beta" code location (e.g. production Perl code us in /usr/code/scripts, BETA Perl code is in /usr/code/beta/scripts; production Perl libraries are in /usr/code/lib/perl and BETA versions of those libraries are in /usr/code/beta/lib/perl, is there an easy way for me to achieve such a setup? The exact requirements are: The code must be THE SAME in production and BETA location. To clarify, to promote any code (library or script) from BETA to production, the ONLY thing which needs to happen is literally issuing cp command from BETA to prod location - both the file name AND file contents must remain identical. BETA versions of scripts must call other BETA scripts and BETA libraries (if exist) or production libraries (if BETA libraries do not exist) The code paths must be the same between BETA and production with the exception of base directory (/usr/code/ vs /usr/code/beta/) I will present how we solved the problem as an answer to this question, but I'd like to know if there's a better way.

    Hi :), I've a little problem, I'd search google and my Wpf's books but I don't found any answer :( I have created a little storyboard : <Storyboard x:Key="whiteAnim" Duration="1"> <ColorAnimation By="Black" To="White" Storyboard.TargetProperty="Background" x:Name="step1"/> <ColorAnimation By="White" To="Black" Storyboard.TargetProperty="Background" x:Name="step2"/> </Storyboard> This animation will change background color from black to white, and from white to black.

  • TFS and code coverage for web application (MVC) assemblies not working

    - by Andrew
    I've got an MVC web application with associated controller tests that run under a TFS build as per normal. I can see the tests running and passing in the build log and they appear in the "Result details for Any CPU/Release" section of the build I also have a number of other assemblies with associated tests that are running in the same build. Tests are passing and the details are being shown in the results and logs just fine. I've enabled code coverage in the build script and the testrunconfig. The coverage is appearing for all assemblies EXCEPT the web application even though it looks like the tests have been run for it. Is there anything obvious that I have missed or some sort of work around that I need to do? I've searched around for a while and haven't found an answer. Has anyone got code coverage working for MVC web applications?

  • telerik mvc grid access cell data to enable columns.Command

    - by AZee
    Hi! I can't seem to find a way to reference the value in a column in the grid, in my case it is the StatusId. Based on the cell value in this row, for the StatusId, I need to return a true or false to the method ".Visible(???)". It would be nice to find the answer in the documentation online but I haven't been able to. I find it hard to believe that I would be the first person who ever needed this functionality. I would be most appreciative of any assistance since no one in the telerik forums know. .Columns(columns => { columns.Command(commands => { commands.Edit().ButtonType(ButtonType); commands.Delete().ButtonType(ButtonType); }).Width(90).Visible(???); Thanks!

  • MySQL Trigger creation

    - by Bruce Garlock
    I have an application where I need to INSERT an auto_increment value from a PK in another table. I know how to do this in PHP, but I need to have this done at the DB level, since I cannot change the program logic. I am new to triggers, so I'm sure this will be an easy answer for someone. Here is what I have so far: DELIMITER // CREATE TRIGGER new_project AFTER INSERT ON m_quality_header FOR EACH ROW BEGIN INSERT INTO m_quality_detail (d_matl_qa_ID) VALUES (NEW.h_matl_qa_ID); END// DELIMITER ; I just want the value of the auto_increment value from h_matl_qa_ID to be inserted as a new record into d_matl_qa_ID. The error I get is: "This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table' But, I don't want to update the table that has the trigger, so why is my current code considered a 'multiple' trigger? This is on MySQL 5.0.45-7.el5 running on a CentOS 5 server (64-bit Intel) If I have to, I can modify the PHP code, but that needs to be the last resort.

  • What is the easiest way to get an embedded upload progress bar using Ruby/Sinatra/Haml/Passenger/ngi

    - by mmr
    I have a website where people can upload 30+mb of data in a single block, and I want to be able to show them the progress of their upload without causing the web page to become unresponsive, similar to how flash uploads work in gmail. There's this question here, but I don't know if that progress bar is embedded in the page or if it's using the browser's progress bar. I'm also a bit of a web newb, so I'm not sure if it's the 'easiest'. I asked the swfupload guys how to do this here, and the answer I got is 'this tool requires some knowledge to use it' without giving me much help in figuring out where to get started. I also asked this question on ServerFault, and got no response, so maybe that was the wrong place to ask. I'm all for learning new things and so forth, but there are a lot of potential pathways to take here. Where should I start, and what do I need to know to make everything work with sinatra, haml, ruby, passenger, and nginx? Thanks!

  • How to add an Interbase connection pool to glassfish?

    - by kgrad
    Hi, I am attempting to add an Interbase connection pool to GlassFish v3 to use EJB 3.1 in a project. The glassfish log appears to be connecting to my database properly, it spits out all my table names and indices. However, I get an error INFO: fetching database metadata SEVERE: could not complete schema update java.lang.NullPointerException at interbase.interclient.ResultSet.local_Close(Unknown Source) ... And when I ping the connection pool from within Glassfish I receive "Ping failed Exception - null". I have the following properties set with my connectionpool: resource type: javax.sql.DataSource Datasource Classname: interbase.interclient.DataSource portNumber: 3050 as well as my database info. I can't seem to find information elsewhere. This question is similar but did not receive an answer. thanks.

  • Newbie Objective C developer question

    I have been looking everywhere for an answer to this question - perhaps I'm looking in the wrong places. Also, I'm brand new to Objective C although I have around 10 years of experience as a developer. for this code: [receiver makeGroup:group, memberOne, memberTwo, memberThree]; what would the method definition look like? - (void)makeGroup:(Group *)g, (NSString *)memberOne, ...? Thanks for any help you can provide. I know this is probably very simple... Thanks, R

  • Help with SQL query (add 5% to users with conditions)

    - by Mestika
    Hi everyone, I’m having some difficulties with a query which purpose is to give users with more than one thread (called CS) in current year a 5% point “raise”. My relational schema looks like this: Thread = (threadid, threadname, threadLocation) threadoffering = (threadid, season, year, user) user = (name, points) Then, what I need is to check: WHERE thread.threadid = threadoffering.threadid AND where threadoffering.year AND threadoffering.season = currentDate AND where threadoffering.User 1 GIVE 5 % raise TO user.points I hope it is explained thoroughly but otherwise here it is in short text: Give a 5 % “point raise” to all users who has more than 1 thread in threadLocation CS in the current year and season (always dynamic, so for example now is year = 2010 and season is = spring). I am looking forward to your answer Sincerely, Emil

  • OT: US Banks: Bank Routing Number and BIC/SWIFT

    - by Konerak
    I know it is a bit offtopic, but I've been having a hard time finding more information to this question, and since this site is visited by a lot of people from the United States, you guys might know/find the answer more easily. Banks in europe each have a SWIFT Number, while US Banks use Routing Numbers. This leads to following questions: Does each bank in the US also carry a BIC number? (SWIFT) Is there a 1-1 relationship between BIC and SWIFT? Is there a list of these numbers somewhere? (background information: we're adding international payments to our bookkeeping application. Users can add international suppliers, but my boss prefered not to change the current supplier table but to have the ROUTING NUMBER in another table, with as PK the BIC. I'm wondering if BIC is a valid choice, or if it should just be BANK ACCOUNT NUMBER.)

  • latex large division sign in a math formula

    - by Anna
    Hi, I have been looking for an answer for some time now, hope you could give me a quick tip. I have an equation with many divisions inside. i.e: $\frac{\frac{a_1}{a_2}} {\frac{b_1}{b_2}}$ To make it more readable, I decided to change the large fraction into "/" sign. i.e. $\frac{a_1}{a_2} / \frac{b_1}{b_2}$ The problem is that the "/" sign remains small, and it is quite ugly. How do I change the "/" sign to have a big font? How do I make it more readable? Thanks.

  • How to not increment the build.number in Ant?

    - by dacracot
    I have many targets in my build.xml for Ant. Generally I am running two via a shell script, one to construct the application and one for cleaning up. The shell script checks the exit status of the construction to see if it should clean up or leave the clutter behind so I can determine what went wrong and fix it. So went all is going well, the majority of the time, Ant is executed once for construction and once for clean up. This results in my build.number being incremented for each execution. So in steady state, my build.number increments by 2. How can a tell Ant to not increment the build.number? I would do this for clean up as I haven't built anything. I know the obvious answer of creating a separate script for clean up only, but I'd rather keep the entire build.xml in one file.

  • How to use Cassandra's Map Reduce with or w/o Pig?

    - by UltimateBrent
    Can someone explain how MapReduce works with Cassandra .6? I've read through the word count example, but I don't quite follow what's happening on the Cassandra end vs. the "client" end. https://svn.apache.org/repos/asf/cassandra/trunk/contrib/word_count/ For instance, let's say I'm using Python and Pycassa, how would I load in a new map reduce function, and then call it? Does my map reduce function have to be java that's installed on the cassandra server? If so, how do I call it from Pycassa? There's also mention of Pig making this all easier, but I'm a complete Hadoop noob, so that didn't really help. Your answer can use Thrift or whatever, I just mentioned Pycassa to denote the client side. I'm just trying to understand the difference between what runs in the Cassandra cluster vs. the actual server making the requests.

  • JFormattedTextField : input time duration value

    - by bguiz
    I want to use a JFormattedTextField to allow the user to input time duration values into a form. Sample valid values are: 2h 30m 72h 15m 6h 0h However I am having limited success with this. Can some one please suggest how this can be accomplished? I am OK if this result can be achieved using a JTextField as well. Thanks! If it is worth anything, here's my current attempt: mFormattedText.setFormatterFactory( new DefaultFormatterFactory( new DateFormatter( new SimpleDateFormat("H mm")))); This sorta works except that: I cannot get h and m to appear as plain text (I tried escaping) * The number of hours has a max *: See @nanda's answer

  • Finding out what user Apache is running as?

    - by AP257
    I want to secure a file upload directory on my server as described beautifully here, but I have one problem before I can follow these instructions. I don't know what user Apache is running as. I've found a suggestion that you can look in httpd.conf and there will be a "User" line, but there is no such line in my httpd.conf file, so I guess Apache is running as the default user. I can't find out what that is, though. So, my question is (are): how do I find out what the default user is do I need to change the default user if the answer is yes and I change the default user by editing httpd.conf, is it likely to screw anything up? Thanks!

  • Admob ads will not display when placed inside a tabview

    - by smith324
    I've been trying to get my ads to display in this type of layout. Tabs - LinearLayout - ListView - header. The header is set via addHeaderView and is displaying normally. If I were to move the ads anywhere else they display normally (so its not a setup issue). Using ads in the header of a listview works fine in my other projects. So this seems to be a very specific problem, the ads simply refuse to display when placed in the header of a listview inside a tabhost. My logs show no activity from admob at all. There is either a bug here or limitation of the sdk. Does anyone have any experience or insight into this issue? EDIT I found the solution. It actually had to do with padding that was in the root of my Tabview. For more checkout my answer here

  • How do I get Nant to use the 4.0 compiler to target .Net 3.5

    - by Rory Becker
    Yes I know that sounds a little bit crazy, but I've got .Net 3.5 deployed in the field and I'd like to use the new 4.0 compiler to target it. There are several new syntactic sugar features in the latest versions of Vb.Net and C# which I would like to use,but I am unable (just yet) to enforce a new version of the .Net framework and CLR on my client base. Before the nay sayers jump in with both feet... I have just successfully used Studio 2010 to compile a 3.5 targeted app which used VB.Net auto properties (A new feature in VB.Net 10) so I know the compilers are capable somehow. So back to my question.... How do I convince Nant to use the 4.0 compiler, but to target .Net 3.5 (CLR 2.0) Update: I am using the csc and vbc tasks and not the Solution task. although I'd settle for an answer on how to do this direct with the compilers at this point.
