  • MKMapView not centered on pin

    - by Val Smith
    Hi all, I have an mkmapview that i'm currently adding pins to, but for some reason when I call [mapView setRegion:[detailItem coordinateRegion] animated:YES]; the pin is off-centered (toward the right side of the screen) on the map. Here is the code for [deailItem coordinateRegion]: - (MKCoordinateRegion)coordinateRegion { MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center = self.coordinate; region.span.longitudeDelta = 0.0075f; region.span.latitudeDelta = 0.0075f; return (region); } I'm setting the coordinateRegion's center to the object's x,y coordinate, so why is it off-center on the map? I feel like there's something I'm missing here... ::Val::

  • Can I tweak a page's appearance using Google Chrome's developer tools?

    - by Nathan Long
    When I'm working on a web page layout, I often use Firefox and Firebug to tweak the CSS until it looks right, then modify my style sheet to match. Right now, I'm trying to fix something that looks fine in other browsers but wrong in Google Chrome. I have pulled up Chrome's Developer Tools, and can inspect the computed style, but don't see a way to edit values and see the results on my page. Is there a way to do this?

  • c#: IsNullableType helper class ?

    - by mark smith
    Hi there, Can anyone help? I have some code that is shared between 2 projects. The code points to a model which basically is a collection of properties that comes from a db. Problem being is that some properties use nullable types in 1 model and the other it doesn't Really the dbs should use the same but they don't .. so for example there is a property called IsAvailble which uses "bool" in one model and the other it uses bool? (nullable type) so in my code i do the following objContract.IsAvailble.Value ? "Yes" : "No" //notice the property .VALUE as its a bool? (nullable type) but this line will fail on model that uses a standard "bool" (not nullable) as there is no property .VALUE on types that are NOT nullable Is there some kind of helper class that i check if the property is a nullable type and i can return .Value .. otherwise i just return the property. Anybody have a solution for this?

  • Data store for capturing votes & aggregating them

    - by Nathan de Vries
    I'm interested in using Node.js as a socket server for stream-based communication with tens of thousands of clients. Clients will be sending votes for particular pieces of content, and receiving near-realtime updates of aggregated vote tallies from the server. The datastore needs to support: Storing the votes Summarising the votes in near-realtime Preventing multiple votes within an arbitrary time period (e.g. clients can only vote once for a piece of content every 1 minute) Something that already has client libraries for Node.js would be preferable.

  • Can MySQL Nested Select return list of results

    - by John
    Hi I want to write a mysql statement which will return a list of results from one table along with a comma separated list of field from another table. I think an example might better explain it Table 1 ======================== id First_Name Surname ---------------------- 1 Joe Bloggs 2 Mike Smith 3 Jane Doe Table 2 ======================== id Person_Id Job_id --------------------- 1 1 1 2 1 2 3 2 2 4 3 3 5 3 4 I want to return a list of people with a comma separated list of job_ids. So my result set would be id First_Name Surname job_id ------------------------------ 1 Joe Bloggs 1,2 2 Mike Smith 2 3 Jane Doe 3,4 I guess the sql would be something like select id, First_Name, Surname, (SELECT job_id FROM Table 2) as job_id from Table 1 but obviously this does not work so need to change the '(SELECT job_id FROM Table 2) as job_id' part. Hope this makes sense Thanks John

  • Pattern matching in Perl ala Haskell

    - by Paul Nathan
    In Haskell (F#, Ocaml, and others), I can do this: sign x | x > 0 = 1 | x == 0 = 0 | x < 0 = -1 Which calculates the sign of a given integer. This can concisely express certain logic flows; I've encountered one of these flows in Perl. Right now what I am doing is sub frobnicator { my $frob = shift; return "foo" if $frob eq "Foomaticator"; return "bar" if $frob eq "Barmaticator"; croak("Unable to frob legit value: $frob received"); } Which feels inexpressive and ugly. This code has to run on Perl 5.8.8, but of course I am interested in more modern techniques as well.

  • JVM/CLR Source-compatible Language Options

    - by Nathan Voxland
    I have an open source Java database migration tool (http://www.liquibase.org) which I am considering porting to .Net. The majority of the tool (at least from a complexity side) is around logic like "if you are adding a primary key and the database is Oracle use this SQL. If database is MySQL use this SQL. If the primary key is named and the database is Postgres use this SQL". I could fork the Java codebase and covert it (manually and/or automatically), but as updates and bug fixes to the above logic come in I do not want to have to apply it to both versions. What I would like to do is move all that logic into a form that can be compiled and used by both Java and .Net versions naively. The code I am looking to convert does not contain any advanced library usage (JDBC, System.out, etc) that would vary significantly from Java to .Net, so I don't think that will be an issue (at worst it can be designed around). So what I am looking for is: A language in which I can code common parts of my app in and compile it into classes usable by the "standard" languages on the target platform Does not add any runtime requirements to the system Nothing so strange that it scares away potential contributors I know Python and Ruby both have implementations on for the JVM and CLR. How well do they fit my requirements? Has anyone been successful (or unsuccesful) using this technique for cross-platform applications? Are there any gotcha's I need to worry about?

  • SQL CLR Stored Procedure and Web Service

    - by Nathan
    I am current working on a task in which I am needing to call a method in a web service from a CLR stored procedure. A bit of background: Basically, I have a task that requires ALOT of crunching. If done strictly in SQL, it takes somewhere around 30-45 mins to process. If I pull the same process into code, I can get it complete in seconds due to being able to optimize the processing so much more efficiently. The only problem is that I have to have this process set as an automated task in SQL Server. In that vein, I have exposed the process as a web service (I use it for other things as well) and want the SQL CLR sproc to consume the service and execute the code. This allows me to have my automated task. The problem: I have read quite a few different topics regarding how to consume a web service in a CLR Sproc and have done so effectivly. Here is an example of what I have followed. http://blog.hoegaerden.be/2008/11/11/calling-a-web-service-from-sql-server-2005/ I can get this example working without any issues. However, whenever I pair this process w/ a Web Service method that involves a database call, I get the following exceptions (depending upon whether or not I wrap in a try / catch): Msg 10312, Level 16, State 49, Procedure usp_CLRRunDirectSimulationAndWriteResults, Line 0 .NET Framework execution was aborted. The UDP/UDF/UDT did not revert thread token. or Msg 6522, Level 16, State 1, Procedure MyStoredProc , Line 0 A .NET Framework error occurred during execution of user defined routine or aggregate 'MyStoredProc': System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.CredentialCache.get_DefaultCredentials() at System.Web.Services.Protocols.WebClientProtocol.set_UseDefaultCredentials(Boolean value) at MyStoredProc.localhost.MPWebService.set_UseDefaultCredentials(Boolean Value) at MyStoredProclocalhost.MPWebService..ctor() at MyStoredProc.StoredProcedures.MyStoredProc(String FromPostCode, String ToPostCode) I am sure this is a permission issue, but I can't, for the life of me get it working. I have attempted using impersonation in the CLR sproc and a few other things. Any suggestions? What am I missing?

  • Finding the FORM that an element belongs to in JavaScript

    - by Magnus Smith
    How can I find out which FORM an HTML element is contained within, using a simple/small bit of JavaScript? In the example below, if I have already got hold of the SPAN called 'message', how can I easily get to the FORM element? <form name="whatever"> <div> <span id="message"></span> </div> </form> The SPAN might be nested within other tables or DIVs, but it seems too long-winded to iterate around .parentElement and work my way up the tree. Is there a simpler and shorter way? If it wasn't a SPAN, but an INPUT element, would that be easier? Do they have a property which points back to the containing FORM? Google says no...

  • iframe as scriptaculous droppable

    - by Nathan
    I have a sortable list and an iframe on the same page. What I'm trying to do is define the <iframe> as a Droppable. Everything works with out errors but when I try to drag a sortable item across the Iframe it stops at the edge. ( if I move it slowly it seems works in firefox) The Iframe is set to DesignMode ="on" so covering it with a transparent element to act as the droppable does not seem applicable here. Anyone know of any other solutions or a better way to handle this?

  • How to retrieve an array from Multidimensional Array.

    - by Mike Smith
    So I have a multi-dimensional array looks like this. $config = array( "First Name" => array( "user" => $_POST['firstname'], "limit" => 35, ), "Last Name" => array( "user" => $_POST['lastname'], "limit" => 40, ), ); I want use the array that's within the config array, so my approach is to use a foreach loop. foreach($config as $field => $data) { } Now I know that $data will be my array, but it seems I can't use it outside of the foreach statement because I only get half of whats already there. Using print_r you can see what it shows outside the loop: Array ( [user] => lastname [limit] => 40 ) But when inside the loop and I use print_r here is my result: Array ( [user] => firstname [limit] => 35 ) Array ( [user] => lastname [limit] => 40 ) I imagine it has to do something with it being with the foreach loop. I've tried to run a foreach on the $data array to populate another array, but that didn't work as well. Is there a way to use this outside of a foreach loop? Sorry if this a dumb question, I'm sure there is a quite a simple answer to this, but I'm just stumped, and can't think of a way to do this. Thanks.

  • Where do I find a list of changes and bug fixes for .Net classes from 3.5 -> 4.0?

    - by Nathan Ridley
    I'm having trouble finding a list of the changes and bug fixes that have been made in the .Net framework for .Net 4.0. They're not easy to find, but surely they exist somewhere? Specifically I want to find out what changes and updates have been made for System.Net.HttpWebRequest and System.Net.CookieContainer, as both are quite bugridden in 3.5 and I want to evaluate whether I should write my code for .Net 4.0 or if I should create some custom classes to work around their issues.

  • Why does Chrome ignore local jQuery cookies?

    - by Nathan Long
    I am using the jQuery Cookie plugin (download and demo and source code with comments) to set and read a cookie. I'm developing the page on my local machine. The following code will successfully set a cookie in FireFox 3, IE 7, and Safari (PC). But if the browser is Google Chrome AND the page is a local file, it does not work. $.cookie("nameofcookie", cookievalue, {path: "/", expires: 30}); What I know: The plugin's demo works with Chrome. If I put my code on a web server (address starting with http://), it works with Chrome. So the cookie fails only for Google Chrome on local files. Possible causes: Google Chrome doesn't accept cookies from web pages on the hard drive (paths like file:///C:/websites/foo.html) Something in the plugin implentation causes Chrome to reject such cookies Can anyone confirm this and identify the root cause?
