  • SQL Server pivots? some way to set column names to values within a row

    - by ccsimpson3
    I am building a system of multiple trackers that are going to use a lot of the same columns so there is a table for the trackers, the tracker columns, then a cross reference for which columns go with which tracker, when a user inserts a tracker row the different column values are stored in multiple rows that share the same record id and store both the value and the name of the particular column. I need to find a way to dynamically change the column name of the value to be the column name that is stored in the same row. i.e. id | value | name ------------------ 23 | red | color 23 | fast | speed needs to look like this. id | color | speed ------------------ 23 | red | fast Any help is greatly appreciated, thank you.

  • Connecting ipad to external monitor

    - by Josh P.
    I am trying to connect my ipad app to an external screen using the following (not checking the correct resolution for no - just want it up and running). - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [window addSubview:[navigationController view]]; if ([[UIScreen screens] count] > 1) { window.screen = [[UIScreen screens] objectAtIndex:1]; } [window makeKeyAndVisible]; return YES; } Is this supposed to redirect everything to the external monitor? How dows it work with touches/gestures? I see in the Apple apps, the controls etc are left on the ipad screen...

  • Getting Started with Fluent NHibernate

    - by Andy
    I'm trying to get into using Fluent NHibernate, and I have a couple questions. I'm finding the documentation to be lacking. I understand that Fluent NHibernate / NHibernate allows you to auto-generate a database schema. Do people usually only do this for Test/Dev databases? Or is that OK to do for a production database? If it's ok for production, how do you make sure that you're not blowing away production data every time you run your app? Once the database schema is already created, and you have production data, when new tables/columns/etc. need to be added to the Test and/or Production database, do people allow NHibernate to do this, or should this be done manually? Is there any REALLY GOOD documentation on Fluent NHibernate? (Please don't point me to the wiki because in following along with the "Your first project" code building it myself, I was getting run-time errors because they forget to tell you to add a reference. Not cool.) Thanks, Andy

  • Dropdown in Access 2007 parameter query. Why not working

    - by waanders
    Hello, I want a Access parameter query to ask an user for a value (a location in this case). When I type [Enter location] in the Criteria field it works fine: I get a dialog box (Enter Parameter Value) with a textbox and my text (Enter Location). So far, so good. This works (the result also). But now I want a dropdown/combobox (instead of a textbox ) for the user to pick a location. I made a form and type Forms![Form1]![CmbLocation] in the Criteria field. Like this: http://office.microsoft.com/en-us/access/HA011170771033.aspx But I still get a textbox (with the reference as textlabel). What am I doing wrong? Has anybody any advice?

  • How does one refer to the game1 class's variables in XNA

    - by user1149068
    I try to refer to an array in the Game1 class by creating an object of the Game1 class with its definition Game1 gameObject; , its declaration gameObject = new Game1(); in the constructor, and its usage gameObject.tileArray[xInt, yInt].treed = true;. The game1 class itself remains unchanged in its class code other than some methods and variables. When I try to use this code in the TreeRegion class it gives me "Object reference not set to an instance of an object," leading me to believe that the game1 class is null somehow. How might one change the class or object in order to refer to game1's variables? Mind you I am self-taught and still rather new to C#. The class that refers to game1: http://pastebin.com/0chEcKfq Game1 itself http://pastebin.com/zLDVzCca

  • UITableView - iPad - Property '' Not Found on Object of type UITableViewCell

    - by user1797508
    I have added a UITableView prototype Cell into a UIView for an iPad application using StoryBoard in Xcode (targeting iOS6). The problem I'm having is that the labels are not being recognized in my viewController when I try to reference them. In my implementation, I have: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"dashboardMessage"; UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } int row = [indexPath row]; cell.messageSender.text = [_matches valueForKey:@"from"]; } The last line is causing an error: Property 'messageSender' Not Found on Object of type UITableViewCell In the cell's header file I have: @interface DashboardMessageCell : UITableViewCell @property (strong, nonatomic) IBOutlet UILabel *messageSender; @property (strong, nonatomic) IBOutlet UILabel *messageDescr; and the header file is imported into the viewController. I'm lost as to what can be causing the issue, any help would be greatly appreciated. Thanks.

  • Can a Client Link to My JavaScript, Hosted on a Different Domain?

    - by DaveDev
    Is it possible for me to supply a client with a snippet of HTML which contains a reference to a javascript file that I host? They want to paste this HTML into their CMS, so that when their page loads, it'll load our content. I was under the impression that there was cross domain security preventing this from being possible. What if, instead of linking to the JavaScript, I gave them the snippet of HTML with the JavaScript already included so instead of <div> <!-- link to js --> </div> I gave them <div> $.get(/*url to my content*/); </div> Would that work?

  • Mac OS X 10.5+ and POSIX

    - by Phil
    Hello, I need to program an authentication module that has to work with Mac OS X 10.6 Snow Leopard and at the same time needs to be POSIX-compliant. I read here: developer.apple.com/leopard/overview/osfoundations.html that since Mac OS X 10.5 Leopard, Mac OS X is POSIX-compliant (to POSIX 1003.1), but working under MAC OS X 10.5 Leopard myself, I can't find any trace of my user name neither in /etc/passwd nor in its successor /etc/master.passwd, which is mentioned here: developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man5/passwd.5.html Instead it says in both files OpenDirectory Service is used, which should be OpenLDAP according to the OpenDirectoryService man-page. Is this still POSIX-compliant ? I guess not. I wonder how Mac OS X would handle my 100% POSIX-compliant code which depends on /etc/passwd ? I would be gratefull if someone could explain the way this works to me. Thank you for your time and trouble. Best regards Phil.

  • Architecture Guidance for designing Workflow Foundation with WCF

    - by Matrix
    We are planning to use WF 3.5 with WCF 3.5 and Entity Framework 1.0 for the upcoming major project. I'm looking for guidance on the architecture side. This new application will be based on typical 3-tier architecture as depicted below: Presentation Tier: ASP.NET Web Forms 3.5 Business Tier: WF 3.5 + BLL's that expose the business logic through WCF service interfaces (using EF for Data Access) Data Tier: SQL Server 2000 Here are the questions: Though the Workflow Foundation has Workflow Services, where we can map the WCF service contracts to a workflow, is this the right way to design the applications? Is EF 1.0 business entities can be used in n-tier apps without sacrificing the tracking changes in the entities? Is there a sample reference application available to look? Thanks.

  • Why is there no .NET Community Process?

    - by michielvoo
    I was doing some research into general topics of software engineering and I came across the Java Community Process website: The JCP is the mechanism for developing standard technical specifications for Java technology. Anyone can register for the site and participate in reviewing and providing feedback for the Java Specification Requests (JSRs), and anyone can sign up to become a JCP Member and then participate on the Expert Group of a JSR or even submit their own JSR Proposal. Seems like a good idea to me, and there are lots of very well written specifications and reference implementations on the JCP website. So why is there no .NET Community Process? Is that something that Microsoft could or should start? Maybe they could install it on Codeplex.net and hand over the keys to the community.

  • iPhone - Image overlay MapKit framework?

    - by Peter
    I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps. Am I missing something here, but can this be done with a none standard map and having different zoom levels? The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.

  • How to handle customers with multiple addresses in CakePHP

    - by Ryan
    I'm putting together a system to track customer orders. Each order will have three addresses; a Main contact address, a billing address and a shipping address. I do not want to have columns in my orders table for the three addresses, I'd like to reference them from a separate table and have some way to enumerate the entry so I can determine if the addressing is main, shipping or billing. Does it make sense to create a column in the address table for AddressType and enumerate that or create another table - AddressTypes - that defines the address enumeration and link to that table? I have found other questions that touch on this topic and that is where I've taken my model. The problem I'm having is taking that into the cakePHP convention. I've been struggling to internalize the direction OneToMany relationships are formed - the way the documentation states feels backwards to me. Any help would be appreciated, Thanks!

  • Desimal data Type Display scale part as zero

    - by Wael Dalloul
    I have Decimal field in SQLserver 2005 table, Price decimal(18, 4) if I write 12 it will be converted to 12.0000, if I write 12.33 it will be converted into 12.3300. Always it's putting zero to the right of the decimal point in the count of Scale Part(4). I was using these in SQL Server 2000, it was not behaving like this, in SQL Server 2000 if I put 12.5 it will be stored as 12.5 not as 12.5000 what SQLServer2005 do. My Question is how to stop SQL Server 2005 from putting zeros to the right of the decimal point?

  • Latest 100 mentions - Twitter api

    - by laurens
    I'm looking to achieve the following: For a specific person, for example BarackObama, I'd like to get the last 100 times/tweets he was mentioned. Not his own tweets but the tweets of others containing @BarackObama. In the end I'd like to have: the person who mentioned, location, datetime. This content should be written to a flat file. I've been experimenting with the Twitter API and Python, with success but haven't yet succeeded achieving the above problem. I know there is a dev sections on the twitter website but they don't provide any example of code!! https://dev.twitter.com/docs/api/1/get/statuses/mentions count=100 .... For me the scripting language or way of doing is not relevant it's the result. I just read on the internet that python and Twitter api are a good match. Thanks a lot in advance!!

  • Is it possible to position an element relative to the border-box of its parent?

    - by Timwi
    Consider the following jsfiddle for reference: http://jsfiddle.net/apmmw2ma/ As you can see, the “inner” box (with the red border) is positioned relative to the outer’s padding-box: left:0 positions it just to the right of outer’s border, and top:100% appears to mean “100% of the content plus padding, but not the border”. Unfortunately, adding box-sizing: border-box to the outer div seems to have no effect. I want to position a child element directly below its parent’s border-box, i.e. the two borders should abut no matter how thick they are. Is this possible?

  • How is the ">" operator implemented (on 32 bit integers)?

    - by Ron Klein
    Let's say that the environment is x86. How do compilers compile the "" operator on 32 bit integers. Logically, I mean. Without any knowledge of Assembly. Let's say that the high level language code is: int32 x, y; x = 123; y = 456; bool z; z = x > y; What does the compiler do for evaluating the expression x > y? Does it perform something like (assuming that x and y are positive integers): w = sign_of(x - y); if (w == 0) // expression is 'false' else if (w == 1) // expression is 'true' else // expression is 'false' Is there any reference for such information?
