  • Can you add a UITableViewController's TableView to another View?

    - by Dan Harrelson
    I've inserted a UITableViewController and it's corresponding UITableView into a simple IB document. The goal is to include the UITableView inside of a parent UIWindow (or UIView) with other "stuff" (anything really) adorning the table. Here's what that might look like in Interface Builder. http://danharrelson.com/images/skitch/iphone-tableview-3-20090701-205535.png I've tried this numerous times and always get to the same place. Build a working subclass of UITableViewController filled with data Customize the UTableView and it's cells including tap targets Add the newly created UITableViewController into an IB document Drag the UITableView out of the UITableViewController and into the main UIView Wire up the UITableViewController to the UITableView Note: adding the UITableViewController in code results in the same problem When running the app in the iPhone emulator or on a device the table displays correctly, but crashes the first time you try and interact with it. A scroll, a tap, anything crashes the app. This seems to be a delegate problem, like the UITableView doesn't know how to communicate back to the UITableViewController, but I have no idea how to correct the problem. So far I have been able to get by by customizing the tableHeaderView to get layouts that suffice, but I'd really prefer to have the other technique work.

  • VB.Net Custom Object Master-Detail Data Binding

    - by clawson
    Since beginning to use VB.Net some years ago I have become slowly familiar with using the data binding features of .Net, however I often find my self bewildered by it's behavior and instead of discover the correct way it should work I find some dirty work around to suit my needs and continue on. Needless to say my problems continue to arise. I am using Custom Objects as the Data Sources for by controls and often entire forms. I find it frustrating to separate business logic and the graphical interface. (That could be a new question entirely.) So for a lot of objects I generate a form which has the DataBindingSource for the object. When I create each from using the New Constructor I explicitly pass to it the object to which it should be bound, and then set this passed object as the DataSource of the BindingSource. (That's a mouthful!) Now the Master object (say, bound to each form) often contains a List of objects which I like to have displayed in a DataGridView. I (sometimes) create and modify these child objects in their own form (again creating a databind the same way as the master form) but when I add them to the List in the master object the DataGridView won't update with the new items. So my question really has a few layers: How can I easily/efficiently/correctly update this DataGridView with the list of Detail objects when I add them to the list of the Master object. Is this approach to DataBinding good/viable. What's the best way to separate business logic from graphical interface. Thanks for the help!

  • WCF: WTF! Does WCF raise the bar or just the complexity level?

    - by rp
    I understand the value of the three-part service/host/client model offered by WCF. But is it just me or does it seem like WCF took something pretty direct and straightforward (the ASMX model) and made a mess out of it? Is there an alternative to using SvcUtil's command line step back in time to generate the proxy? With ASMX services a test harness was automatically provided; is there a good alternative today with WCF? I appreciate that the WS* stuff is more tightly integrated with WCF and hope to find some payoff for WCF there, but geeze, otherwise I'm perplexed. Also, the state of books available for WCF is abysmal at best. Juval Lowy, a superb author, has written a good O'Reilly reference book "Programming WCF Services" but it doesn't do that much (for me anyway) for learning now to use WCF. That book's precursor (and a little better organized, but not much, as a tutorial) is Michele Leroux Bustamante's Learning WCF. It has good spots but is outdated in place and its corresponding Web site is gone. Do you have good WCF learning references besides just continuing to Google the bejebus out of things? Thanks, rp

  • TRibbon's large button's image is not centered...any ideas? easy to demonstrate at design-time.

    - by X-Ray
    i'm using delphi 2009 (updates 1, 2, 3, 4). i'm seeing something quite peculiar. the image on the button is not centered in the button when i have a large button with a large glyph! rather than being centered, the left part of the glyph starts at the center of the button. a clue is that when i: go into the action editor and select the action use the ImageIndex combobox in the object inspector, the list is empty (normally i'd see the available images in the combobox). it seems as though there's an image width property i've failed to set or an imagelist not correctly configured. i've expected the glyph on a large button should be 32x32. try the following: paste these components into an empty form add a 32x32 image to the image list set the Action1 imageindex to 0 you'll immediately see what i mean! can anyone tell me why it looks that way? i find it interesting that the ribbon demo app doesn't show this problem. i even tried the same image. thank you! object ActionManager1: TActionManager ActionBars = < item Items = < item Action = Action1 Caption = '&Action1' ImageIndex = 0 CommandProperties.ButtonSize = bsLarge end> ActionBar = RibbonGroup1 end> LargeDisabledImages = img3232 LargeImages = img3232 Left = 376 Top = 184 StyleName = 'Ribbon - Luna' object Action1: TAction Caption = 'Action1' ImageIndex = 0 end end object Ribbon1: TRibbon Left = 0 Top = 0 Width = 693 Height = 147 ActionManager = ActionManager1 Caption = 'Ribbon1' Tabs = < item Caption = 'RibbonPage1' Page = RibbonPage1 end> ExplicitLeft = 232 ExplicitTop = 80 ExplicitWidth = 0 DesignSize = ( 693 147) StyleName = 'Ribbon - Luna' object RibbonPage1: TRibbonPage Left = 0 Top = 54 Width = 692 Height = 93 Caption = 'RibbonPage1' Index = 0 object RibbonGroup1: TRibbonGroup Left = 4 Top = 3 Width = 54 Height = 86 ActionManager = ActionManager1 Caption = 'RibbonGroup1' GroupIndex = 0 end end end object img3232: TImageList Height = 32 Width = 32 Left = 376 Top = 256 end

  • Segment register, IP register and memory addressing issue!

    - by Zia ur Rahman
    In the following text I asked two questions and I also described that what I know about these question so that you can understand my thinking. Your precious comments about the below text are required. Below is the Detail of 1ST Question As we know that if we have one mega byte memory then we need 20 bits to address this memory. Another thing is each memory cell has a physical address which is of 20 bits in 1Mb memory. IP register in IAPX88 is of 16 bits. Now my point of view is, we can not access the memory at all by the IP register because the memory need 20 bit address to be addressed but the IP register is of 16 bits. If we have a memory of 64k then IP register can access this memory because this memory needs 16 bits to be addressed. But incase of 1mb memory IP can’t.tell me am i right or not if not why? Suppose physical address of memory is 11000000000000000101 Now how can we access this memory location by 16 bits. Below is the detail of Next Question: My next question is , suppose IP register is pointing to memory location, and the segment register is also pointing to a memory location (start of the segment), the memory is of 1MB, how we can access a memory location by these two 16 bit registers tell me the sequence of steps how the 20 bits addressable memory location is accessed . If your answer is, we take the segment value and we shift it left by 4 bits and then add the IP value into it to get the 20 bits address, then this raises another question that is the address bus (the address bus should be 20 bits wide), the registers both the segment register and the IP register are of 16 bits each , now if address bus is 20 bits wide then this means that the address bus is connected to both these registers. If its not the case then another thing that comes into my mind is that both these registers generate a 20 bit address and there would be a register which can store 20 bits and this register would be connected to both these register and the address bus as well.

  • Weird error running com-exposed assembly

    - by Bernabé Panarello
    I am facing the following issue when deploying a com-exposed assembly to my client's. The COM component should be consummed by a vb6 application. Here's how it's done 1) I have one c# project which has a class with a couple of methods exposed to COM 2) The project has references to multiple assemblies 3) I compile the project, generating a folder (named dllcom) that contains the assembly plus all the referenced dlls 4) I include in the folder a .bat which does the following: regasm /u c:\dllcom\LibInsertador.dll del LibInsertador.tlb regasm c:\dllcom\LibInsertador.dll /tlb:c:\dllcom\LibInsertador.tlb /codebase c:\dllcom\ pause 5) After running the bat locally in many workstations of my laboratory, i'm able to consume the generated tlb from my vb6 application without any problems. I'm even able to update the dll by only means of running this bat, without having to recompile the vb6 application. I mean that im not having issues of vb6 fiding and invoking the exposed com object. The problem 6) I send the SAME FOLDER to my client 7) They execute the .bat locally, without any errors 8) They execute the vb6 application, vb6 finds the main assembly, the .net code seems to run correctly (it's even able to generate a log file) until it has to intantiate it's first referenced assembly. Then, they get the following exception: "Could not load type 'GYF.Common.TypeBuilder' from assembly 'GYF_Common, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'." Where "GYF.Common" is an assembly referenced by LibInsertador and TypeBuilder is a class contained in GYF.Common. GYF.Common is not a signed assembly and it's not in the GAC, just in the same folder with Libinsertador. According to .net reflector, the version is correct. ¿Any ideas about what could be happening?

  • jQuery hover DIV- stay active if they hover over the DIV itself

    - by Lock
    I have a DIV that opens up when an image is hovered. When the user leaves the image, the div disappears after a timeout. How can I make it so that the DIV will stay active if the user was to hover over the DIV itself? So the DIV will stay active as long as the user is on the image or the DIV itself? I am using the following: $(document).ready(function() { $(".hover").hover( function(e){ if ( $("#status").is(":hidden")) { var ref = $(this).attr("wsref"); var url = "https://site/_ref/shop/_base/order_status.php?action=getstatus&ref="+ref+"&sid="+Math.random(); $("#status").show(); var height = $(".status").height(); var width = $(".status").width(); leftVal = e.pageX - width -10 + "px"; topVal = e.pageY - height -10 + "px"; $("#status").css({left:leftVal,top:topVal}); $("#status").html("<div id='loading'></div>").load(url); } }, function() { if ( $("#status").is(':visible')) { setTimeout('$("#status").hide()',0); } }); }); HTML <a href="#"><img class="hover" title="Order Received" name="Order Received" src="https://site/_ref/images/cart.png" wsref="002731"/></a>

  • jqGrid - edit function never getting called

    I'm having a problem with JQGrid using ASP.NET MVC.

  • Getting browser to make an AJAX call ASAP, while page is still loading

    - by Chris
    I'm looking for tips on how to get the browser to kick off an AJAX call as soon as possible into processing a web page, ideally before the page is fully downloaded. Here's my approximate motivation: I have a web page that takes, say, 5 seconds to load. It calls a web service that takes, say, 10 seconds to load. If loading the page and calling the web service happened sequentially, the user would have to wait 15 seconds to see all the information. However, if I can get the web service call started before the 5 second page load is complete, then at least some of the work can happened in parallel. Ideally I'd like as much of the work to happen in parallel as possible. My initial theory was that I should place the AJAX-calling javascript as high up as possible in the web page HTML source (being mindful of putting it after the jquery.js include, because I'm making the call using jquery ajax). I'm also being mindful not to wrap the AJAX call in a jquery ready event handler. (I mention this because ready events are popular in a lot of jquery example code.) However, the AJAX call still doesn't seem to get kicked off as early as I'm hoping (at least as judged by the Google Chrome "Timeline" feature), so I'm wondering what other considerations apply. One thing that might potentially be detrimental is that the AJAX call is back to the same web server that's serving the original web page, so I might be in danger of hitting a browser limit on the # of HTTP connections back to that one machine? (The HTML page loads a number of images, css files, etc..)

  • JAXB boolean handling oddities and JSF

    - by finrod
    There is a known bug in JAXB: https://jaxb.dev.java.net/issues/show_bug.cgi?id=733 JAXB does not properly generate boolean field getters and setters, this bug is left unfixed for backwards compatibility. A JAXB plugin exists and will ensure that the following getters and setters for boolean fields are generated: setXXX(Boolean value) is generated getXXX() is generated If the boolean attribute specifies default value in the XSD, then getXXX() returns boolean, If the boolean attribute does not specify default in the XSD, then getXXX() returns Boolean. Problem: trying to edit/view the XXX field in a JSF component (such as checkbox) does not work - the component is disabled. I have not traced this in depth but the assumption (backed by the workaround below) is that JSF EL resolver (or whathaveyou) looks for Boolean getXXX() method and since it does not find it, the component is disabled. Workaround: If I change the getXXX() method to always return Boolean, then everything goes. Questions: What are your ideas to address this problem? Have I missed some customization for the boolean-getter JAXB plugin? Is it possible (does it make sense) to alter JSF resolver (or whathaveyou) so that if Boolean getXXX() is not found, it will fall back to boolean getXXX()? I would prefer not to manually intervene and change all the generated getXXX() methods to return Boolean instead of boolean.

  • Setting UIImage dimensions on UITableViewCell image

    - by bbrown
    I've got a standard UITableViewCell where I'm using the text and image properties to display a favicon.ico and a label. For the most part, this works really well since UIImage supports the ICO format. However, some sites (like Amazon.com say) have favicon.icos that make use of the ICO format's ability to store multiple sizes in the same file. Amazon stores four different sizes, all the way up to 48x48. This results in most images being 16x16 except for a few that come in at 32x32 or 48x48 and make everything look terrible. I have searched here, the official forum, the documentation, and elsewhere without success. I have tried everything that I could think of to constrain the image size. The only thing that worked was an undocumented method, which I'm not about to use. This is my first app and my first experience with Cocoa (came from C#). In case I wasn't clear in what I'm looking for, ideally the advice would center around setting the dimensions of the UIImage so that the 48x48 version would scale down to 16x16 or a method to tell UIImage to use the 16x16 version present in the ICO file. I don't necessarily need code: just a suggestion of an approach would do me fine. Does anyone have any suggestions? (I asked in the official forum as well because I've sunk more than a day into this already. If a solution is posted there, I'll put it here as well.)

  • Crystal Reports .Net Guidance

    - by Ken Ray
    We have been using .Net and Visual Studio for the last six years, and early on developed a number of web based reporting applications using the .Net version of Crystal Reports that was bundled with Visual Studio. My overall opinion of that product has been, to say the least, rather unimpressed. It seemed to be incredibly difficult and convoluted to use, we had to make security changes, install various extra software, and so on. Now, we are moving to VS2008 and version 3.5 of the .Net framework, and the time has come to redevelop some of these old applications. The developers who used (and somehow mastered) Crystal .Net have long gone, and I am facing a decision - do we stick with Crystal Reports or move to something else. We also have the "full" version of Crystal Reports XI at our disposal. The way we use the product is to product pdf versions of data extracted from various databases. While some apps use the inbuilt Crystal Reports viewer as well, this seems to be redundant now with the flexibility of grid views - but there is still the need to produce a pdf version of the data in teh grid for printing, or in Excel format to download. What is the concensus? Is Crystal Reports .Net worth persisting with, or should we work out how to use version XI? Alternatively, is there a simple and low cost way to generate pdf reports without using Crystal? What good sources of "how to" information have others found and recommend? Are there suitable books, designed for VS2008 / .Net 3.5 development that you have used and found of benefit? Thanks in advance.

  • Getting value from href using jQuery

    - by bateman_ap
    Hi, I wonder if anyone can help with a jQuery problem I am having. I am using the tooltips from the Jquery Tools library to create a popup window when mousing over an hrefed image, this I want to use to cusomise the call to change the content in the DIV. The links I am using are in the form: <a href="/venue/1313.htm" class="quickView"><img src="/images/site/quickView83.png" alt="Quick View" width="83" height="20" /></a> The code I am using to trigger the tip is: $(".quickView").live('mouseover', function() { if (!$(this).data('init')) { $(this).data('init', true); ajax_quickView(); $(this).tooltip ({ /* tooltip configuration goes here */ tip: "#quickViewWindow", position: "right", offset: [0, -300], effect: 'slide' }); $(this).trigger('mouseover'); } }); I have tried the following function to grab the ID (in the example above, 1313) from the link: function ajax_quickView(){ var pageNum = $("a.quickView").attr("href").match(/venue/([0-9]+)/).htm[1]; $("#quickViewWindow").load("/quick-view/", function(){}) } However I think this is where it falls down, I think my regex is prob to blame... Once I get the var pageNum I presume I can just pass it into the .load as: $("#quickViewWindow").load("/quick-view/", {id : pageNum }, function(){}) Many thanks

  • PHP Localization Best Practices? gettext?

    - by nute
    We are in the process of making our website international, allowing multiple languages. I've looked into php's "gettext" however, if I understand it right, I see a big flaw: If my webpage has let's say "Hello World" as a static text. I can put the string as <?php echo gettext("Hello World"); ?>, generate the po/mo files using a tool. Then I would give the file to a translator to work on. A few days later we want to change the text in English to say "Hello Small World"? Do I change the value in gettext? Do I create an english PO file and change it there? If you change the gettext it will consider it as a new string and you'll instantly loose the current translation ... It seems to me that gradually, the content of the php file will have old text everywhere. Or people translating might have to be told "when you see Hello World, instead, translate Hello Small World". I don't know I'm getting confused. In other programming languages, I've seen that they use keywords such as web.home.featured.HelloWorld. What is the best way to handle translations in PHP? Thanks

  • Overlay an HTML page with an HTML form

    - by jah
    Hi folks, this is a question about the best way (or least effort of the best ways) to overlay an html page with a form. Best in this context meaning best user experience whilst meeting the functional requirements. Let's say I have a page with a short form on it; the user has to enter some financial details. To assist the user to enter an accurate value for one of the fields there's another, much longer form. The longer form needs to be displayed only if the user requests the help. For users without javascript, clicking a link will submit the short form (persisting already filled fields in a session) and the server will respond with the long form. They'll submit the long form and the server will combine the submitted data with the persisted data and serve the short form again - with the fields populated. For users with javascript I want to overlay the short form page (in a lightbox stylee) with the long form, allow them to populate the long form and then go back to the short form with less round-trips to the server. Do I: Overlay the short form page with an iframe whose target is the long form? Request the long form over ajax and stuff it into a div? Generate the long form entirely on the client-side? Some other wizadry I haven't thought of? A short explanation of the best mechanism will do me very nicely indeed. Thank you very much!

  • HTML - Correct way of coding a checkbox with a Label.

    - by egarcia
    I've been using formtastic in order to generate HTML forms on rails applications. My question, however, is really HTML-related. Today I found a strange behaviour on the way formtastic generates checkboxes (fields of type :boolean on formtastic lingo). The rest of the fields (non-checkboxes) are generated this way: <li> <label for="my_textbox_field">My TextBox</label> <input id="my_textbox_field" type="text" ... > </li> Checkboxes, however, are enclosed inside their <label> tags completely - like this: <li> <label for="my_boolean_field"> <input id="my_boolean_field" type="checkbox" ... > This is my boolean field </label> </li> Formtastic phylosophy seems to be based on the Learning to Love Forms presentation. In effect, on slide 36 of that presentation this structure is suggested for checkboxes. I guess in the presentation itself the presenter explained why this was done, but it is not written on the slides. Can anyone tell me why enclosing checkboxes inside their <label> tag might be a good idea, as opposed to putting them outside, like with textboxes?

  • xsd.exe - schema to class - for use with WCF

    - by NealWalters
    I have created a schema as an agreed upon interface between our company and an external company. I am now creating a WCF C# web service to handle the interface. I ran the XSD utility and it created a C# class. The schema was built in BizTalk, and references other schemas, so all-in-all there are over 15 classes being generated. I put [DataContract} attribute in front of each of the classes. Do I have to put the [DataMember] attribute on every single property? When I generate a test client program, the proxy does not have any code for any of these 15 classes. We used to use this technique when using .asmx services, but not sure if it will work the same with WCF. If we change the schema, we would want to regenerate the WCF class, and then we would haev to each time redecorate it with all the [DataMember] attributes? Is there an newer tool similar to XSD.exe that will work better with WCF? Thanks, Neal Walters SOLUTION (buried in one of Saunders answer/comments): Add the XmlSerializerFormat to the Interface definition: [OperationContract] [XmlSerializerFormat] // ADD THIS LINE Transaction SubmitTransaction(Transaction transactionIn); Two notes: 1) After I did this, I saw a lot more .xsds in the my proxy (Service Reference) test client program, but I didn't see the new classes in my intellisense. 2) For some reason, until I did a build on the project, I didn't get all the classes in the intellisense (not sure why).

Is this a 64bit issue? Thanks, Rich

  • Adding an observer to UIImageView? observer & notifications

    - by sagar
    Each class has almost one method named addObserver [imgVURL addObserver:<#(NSObject *)observer#> forKeyPath:<#(NSString *)keyPath#> options:<#(NSKeyValueObservingOptions)options#> context:<#(void *)context#>] Here, imgVURL is an image which is going to be load an image asynchronously. When image will be loaded dynamically - other class will set an image from loaded data. Now, my question is how can we add an observer to UIImageView's instance. Observer and notifications are same or not ? If it is not then what's different ? Let's have some sample code That I did in my project to understand my question. // locating image view from Scroll view by it's tag imgVURL=(UIImageView*)[scrMain viewWithTag:(kTagImagesTag+i)]; // ImageViewURL is a class which contains methods of // didReceiveResponse // didReceiveData // connection ImageViewURL *tmp=[[ImageViewURL alloc] init]; // it has a nonatomic property which will take the reference of my image view tmp.imgV=imgVURL; // now I will pass a url from my an array to property strURL // in strUrl I have custom setter // in which I am initializing a connection tmp.strUrl=[NSURL URLWithString:[[tblmain objectAtIndex:i] valueForKey:@"url"]]; // from ImageViewURL.m file -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; // NSLog@"ImageView Ref From - %@",imgV); // see imgV has reference of my -> imgVURL (nonatomic,assign) imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; } // as you can see in above code many many images are loaded asynchronously // now How can I add an observer to an imageview whether it received or not.

    - by William
    So I'm trying to create a forum with avatars, but right now the text is going below the avatars and not beside them. How can I fix this? Here is the CSS: .postbox{ text-align: left; margin: auto; background-color: #dbfef8; border: 1px solid #82FFCD; width: 100%; margin-top: 10px; } .postfooter{ width: 100%; border-top: 1px solid #82FFCD; } .postheader{ width: 100%; border-bottom: 1px solid #82FFCD; } .posttext{ width: 70%; text-align: left; border: 1px solid #82FFCD; } .postavi{ width: 20%; text-align: left; border: 1px solid #82FFCD; } and here is the html: <div class="postbox"><div class="postheader"> <b><span>CyanPrime!!~::##Admin##::~</span></b> </div> <div class="postavi"><img src="http://prime.programming-designs.com/test_forum/images/avatars/hacker.png" alt="hacker"/></div><div class="posttext">Let's test the Hacker Avatar.</div> <div class="postfooter"> [<a href="http://prime.programming-designs.com/test_forum/viewthread.php?thread=25">Reply</a>] 0 posts omitted. </div> </div>

  • Boost Mersenne Twister: how to seed with more than one value?

    - by Eamon Nerbonne
    I'm using the boost mt19937 implementation for a simulation. The simulation needs to be reproducible, and that means storing and potentially reusing the RNG seeds later. I'm using the windows crypto api to generate the seed values because I need an external source for the seeds and not because of any particular guarantees of randomness. The output of any simulation run will have a note including the RNG seed - so the seed needs to be reasonably short. On the other hand, as part of the analysis of the simulation, I'll be comparing several runs - but to be sure that these runs are actually different, I'll need to use different seeds - so the seed needs to be long enough to avoid accidental collisions. I've determined that 64-bits of seeding should suffice; the chance of a collision will reach 50% after about 2^32 runs - that probability is low enough that the average error caused by it is negligible to me. Using just 32-bits of seed is tricky; the chance of a collision reaches 50% already after 2^16 runs; and that's a little too likely for my tastes. Unfortunately, the boost implementation either seeds with a full state vector - which is far, far too long - or a single 32-bit unsigned long - which isn't ideal. How can I seed the generator with more than 32-bits but less than a full state vector? I tried just padding the vector or repeating the seeds to fill the state vector, but even a cursory glance at the results shows that that generates poor results.

  • Generating all unique combinations for "drive ya nuts" puzzle

    - by Yuval A
    A while back I wrote a simple python program to brute-force the single solution for the drive ya nuts puzzle. The puzzle consists of 7 hexagons with the numbers 1-6 on them, and all pieces must be aligned so that each number is adjacent to the same number on the next piece. The puzzle has ~1.4G non-unique possibilities: you have 7! options to sort the pieces by order (for example, center=0, top=1, continuing in clockwise order...). After you sorted the pieces, you can rotate each piece in 6 ways (each piece is a hexagon), so you get 6**7 possible rotations for a given permutation of the 7 pieces. Totalling: 7!*(6**7)=~1.4G possibilities. The following python code generates these possible solutions: def rotations(p): for i in range(len(p)): yield p[i:] + p[:i] def permutations(l): if len(l)<=1: yield l else: for perm in permutations(l[1:]): for i in range(len(perm)+1): yield perm[:i] + l[0:1] + perm[i:] def constructs(l): for p in permutations(l): for c in product(*(rotations(x) for x in p)): yield c However, note that the puzzle has only ~0.2G unique possible solutions, as you must divide the total number of possibilities by 6 since each possible solution is equivalent to 5 other solutions (simply rotate the entire puzzle by 1/6 a turn). Is there a better way to generate only the unique possibilities for this puzzle?

  • Fluent config not generating mapping files

    - by rboarman
    Hello, I am trying to get Fluent nHibernate to generate mappings so I can take a look at the files and the sql. My code is based on this post and on what I can glean from the documentation. http://stackoverflow.com/questions/1375146/fluent-mapping-entities-and-classmaps-in-different-assemblies I am using the latest code from git. Here’s my config code: Configuration cfg = new Configuration(); var ft = Fluently.Configure(cfg); //DbConnection by fluent ft.Database ( MsSqlConfiguration .MsSql2008 .ConnectionString("……") .ShowSql() .UseReflectionOptimizer() ); //get mapping files. ft.Mappings(m => { //set up the mapping locations m.FluentMappings.AddFromAssemblyOf<Entity>() .ExportTo(@"C:\temp"); m.Apply(cfg); }); I also tried: var sessionFactory = Fluently.Configure() .Database(MsSqlConfiguration .MsSql2008 .ShowSql() .ConnectionString(“……")) .Mappings(p => p.FluentMappings .AddFromAssemblyOf<Entity>() .ExportTo(@"c:\temp\")) .BuildSessionFactory(); I have verified that the connection string is correct. The issue is that no mapping files show up in the ExportTo folder and no sql code shows up in the output window or in the log file. No errors or exceptions are generated either. I have no idea where to go from here. Thank you in advance. Rick
