• Best Ruby ORM for Wrapping around Legacy MSSQL Database?

  - by Technocrat

  Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support mssql through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in MSSQL. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the MSSQL app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with MSSQL but never to do anything quite like this. Any suggestions?

• Code reviews for larger ASP.NET MVC team using TFS

  - by Parrots

  I'm trying to find a good code review workflow for my team. Most questions similar to this on SO revolve around using shelved changes for the review, however I'm curious about how this works for people with larger teams. We usually have 2-3 people working a story (UI person, Domain/Repository person, sometimes DB person). I've recommended the shelf idea but we're all concerned about how to manage that with multiple people working the same feature. How could you share a shelf between multiple programmers at that point? We worry it would be clunky and we might easily have unintended consequences moving to this workflow. Of course moving to shelfs for each feature avoids having 10 or so checkins per feature (as developers need to share code) making seeing the diffs at code review time painful. Has anyone else been able to successfully deal with this? Are there any tools out there people have found useful aside from shelfs in TFS (preferably open-source)?

• scaleX scaleY increasing left, top margin, and line spacing

  - by Mark

  If you have Text with a font that is 72 point for example (and scaleX scaleY = 1) you can achieve the same size with a font size of 12 and scaleX,scaleY = 6. For reasons that would take too long to explain I am applying a large scale factor as in the latter example. The problem is, even though the text is the same size, the line spacing and left and top margins have all been increased but I want them to be the same size as well. As far as the line spacing, I discovered that TextFormat.leading was being automatically increased when scaleX, scaleY was greater than 1, so I just had to reset TextFormat.leading back to 0. That leaves the left and top margins, and I have no idea how those are being increased. I tried TextFormat.blockIndent=0 and TextFormat.leftMargin=0 (and also ignorePadding=true) and it had no effect. And have no clue how to reset the top margin either to its orginal size, in case anyone has an idea for all these.

• QLocale, what is the scope of the global QLocale::setDefault()?

  - by ALoopingIcon

  Problem: I have a QT based multiplatform (win,mac,*nix) application that parses ascii files containing decimal numbers. parsing is done using a variety of different code pieces that use anything from qt string stuff, c++ stdin, oldstyle scanf, etc. ascii files have always the '.' (dot) as separated decimal (e.g. in the file to be parsed 1/10 is written 0.1 as standard in many countries). people using the application within a OS localized for using comma separated decimal encounter a lot of problems (e.g. for french users scanf expect to find 0,1 as a valid textual representation of 1/10 and if they find 0.1 scanf will parse it as 0) How can I be sure that the OS Locale indication of how decimal point has to be written is always ignored? Is it safe assuming that adding QLocale::setDefault(QLocale(QLocale::English,QLocale::UnitedStates)); is enough to get rid of all these problems? Any suggestion for portable ways of setting the locale globally?

• Could not able to register the third party DLL using regsvr32

  - by Mahadev Malkar

  i have been trying to register the third party dll file using the regsvr32 command, but it keeps giving me the error that 'the dll doesn't have a entry point, dll could not be registered'. Is it possible to register the dll and use it as a COM component in .NET ? Or I want to use that dll as a COM component in c#.NET. Is there any way to use that dll as COM Component. When i tried to use it as COM component, the dll file, its methods, interfaces are visible in .NET. but when i tried to use any of that interface it gives me error as 'Retrieving the COM class factory for component with CLSID {C4CC4F47-2AF6-41FA-A43D-01E8B3050D3F} failed due to the following error: 80040154.'. Plz tell me any solution.

• Java SOAP WSDL 1.1 message sending all the parameters (even future ones)

  - by Eduardo

  I have to communicate with a SOAP Web Service defined in a WSDL 1.1. All the parameters are optional in the WSDL like: <xsd:element name="Submitter" type="xsd:string"/> but if I do not send them I get an error because the parameter was not sent, so instead I have to send an empty string for any parameter I do not intent to send. So instead of not sending the element I have to send: <Submitter></Submitter> The problem is that the WebService publisher does not have any problem adding new parameters at any point in time but I must sent at least an empty string for all the parameters. How may I call this WebService in Java so every time I call the WebService the WSDL is read so that all the parameters are sent having the parameters I care for are actually filled with the data I provide? I am currently using Apache CXF but I am open to anything to solve this problem.

• Hide long text except the first two paragraphs

  - by Barbara

  I have a very long text and I need to hide everything except the first two paragraphs. For various reasons I'd rather not use jquery for this site. Can this be done with css only? I know nth-child most likely will do the trick but I'm having troubles coming up with a specific rule. <div class="text"> <p>display<p> <p>display</p> <p>hide from this point</p> <p>...</p> </div>

• how to tesselate bezier triangles?

  - by Cheery

  My concern are quadratic bezier triangles which I'm trying to tesselate for rendering them. I've managed to implement this by subdividing the triangle recursively like described in a wikipedia page. Though I'd like to get more precision to subdivision. The problem is that I'll either get too few subdivisions or too many because the amount of surfaces doubles on every iteration of that algorithm. In particular I would need an adaptive tesselation algorithm that allows me to define the amount of segments at the edges. I'm not sure whether I can get that though so I'd also like to hear about uniform tesselation techniques. Hardest trouble I have trouble with calculating normals for a point in bezier surface, which I'm not sure whether I need, but been trying to solve out.

• Increasing FD_SETSIZE

  - by user1633717

  I need to increase the FD_SETSIZE value from 1024 to 4096. I know it'd be better to use poll()/epoll() but I want to understand what are pros/cons. The main question is: have I to recompile glibc? I read several thread where the change of .h after changing FD_SETSIZE works recompiling only the user application. Reading the glibc code (and the kernel too), actually it seems to me that if I want to use select(), FD_* macro and so on, I have to recompile all because the size of fd_set is changed. At this point I have to recompile all not only my application because if in the system there is an another "common" application that uses select and friends, I could have problem. Am I right?

• Connect android to database

  - by danny

  I am doing a school project where we need to create an android application which needs to connect to a database. the application needs to gain and store information for people's profiles on the database. But unfortunatly we are a little bit stuck at this point because there are numerous ways to link the application such as http request through apache or through the SOAP/REST protocol. But it's really hard to find good instructions or tutorials on the problem since I can't really find them. Maybe that's cause i'm probably using the wrong words on google. Unfortunately I have little relevant information. So if anyone can help me with finding relevant links to good online tutorials or howto's than those are very welcome.

• Options for header in raw byte file.

  - by Tim

  I have a large raw data file (up to 1GB) which contains raw samples from a USB data logger. I need to store extra information relating to the file (sample rate, description, trigger point, last seek position etc) and was looking into adding this as a some sort of header. The header file should ideally be human readable and flexible so I've so far ruled out some sort of binary serialization into a header. I also want to avoid two separate files as they could end up separated when copied or backed up. I remembered somebody telling me that newer *.*x Microsoft Office documents are actually a number of files in a zip. Is there a simple way to achieve this? Could I still keep the quick seek times to the raw file?

• EntityDataSource Unable to configure to Entity Model

  - by photo_tom

  I'm doing my first test asp.net3.5 app using EntityDataSource. I've got the basic project built and the Entity model created and compiled. Database is a local sqlexpress one in app_data directory. When I put the <asp:EntityDataSource /> control on the page and try to configure it, I'm getting the message "The list of named connections could not be loaded because the configuration could not be opened". At this point, everything in the project is "auto-created" by Visual Studio 2008sp1. I confused as I cannot find any information on how to correct from this message.

• How can I have a Windsor IoC container that can be shared amongst my classes but not shared across m

  - by Si Keep

  I am building a set of class libraries that produce office open xml based reports and I am using a static Windsor IoC container. My problem is that one possible entry point to the reporting system is via a web front end which means that the reporting systems static IoC Container is being shared amongst multiple web requests which causes exceptions as for each new request the reporting system is trying re-register components in Windsor that were already registered by an earlier request. I dont want to move the registration into the web app global.asax as my reporting system will no longer be stand-alone. How can I have a Windsor IoC container that can be shared amongst my reporting classes but not shared across multiple web requests?

• CakePHP HABTM Filtering

  - by James Haigh

  Hi, I've got two tables - users and servers, and for the HABTM relationship, users_servers. Users HABTM servers and vice versa. I'm trying to find a way for Cake to select the servers that a user is assigned to. I'm trying things like $this->User->Server->find('all'); which just returns all the servers, regardless of whether they belong to the user. $this->User->Server->find('all', array('conditions' => array('Server.user_id' => 1))) just gives an unknown column SQL error. I'm sure I'm missing something obvious but just need someone to point me in the right direction. Thanks!

• OpenSocial and its usages

  - by Paul Knopf

  I have looked for some explanation on the exact usages for the set of standards known as OpenSocial. I need some clarification if I can use OpenSocial like the following. I would like to create one library used to community with an OpenSocial api for use in my website that will not 'behave' like an application described by common sites like facebook and myspace. I'm not making a myspace of facebook application, I'm creating my own website and I want users to be able to find friends. I would like to allow users to store usernames and passwords for various OpenSocial-supported social networks. I would also like to use the api to sync events from my web site to their specified social network. I would also like to allow my users to view a list of friends and invite them. Is it possible to create one library that supports OpenSocial and simple "point" to and social network that supports it to get a list of friends and etc?

• Perl Regex Mismatch Issue

  - by Russell C.

  This is a really basic regex question but since I can't seem to figure out why the match is failing in certain circumstances I figured I'd post it to see if anyone else can point out what I'm missing. I'm trying to pull out the 2 sets of digits from strings of the form: 12309123098_102938120938120938 1321312_103810312032123 123123123_10983094854905490 38293827_1293120938129308 I'm using the following code to process each string: if($string && $string =~ /^(\d)+_(\d)+$/) { if(IsInteger($1) && IsInteger($2)) { print "success ('$1','$2')"; } else { print "fail"; } } Where the IsInterger() function is as follows: sub IsInteger { my $integer = shift; if($integer && $integer =~ /^\d+$/) { return 1; } return; } This function seems to work most of the time but fails on the following for some reason: 1287123437_1268098784380 1287123437_1267589971660 Any ideas on why these fail while others succeed? Thanks in advance for your help!

• mysql database design: thread and reply of a reply?

  - by ajsie

  in my forum i have threads and replies. one thread has multiple replies. but then, a reply can be a reply of an reply (like google wave). because of that a reply has to have a column "reply_id" so it can point to the parent reply. but then, the "top-level" replies (the replies directly under the thread) will have no parent reply. so how can i fix this? how should the columns be in the reply table (and thread table). at the moment it looks like this: threads: id title body replies: id thread_id (all replies will belong to a thread) reply_id (here lies the problem. the top-level replies wont have a parent reply) body what could a smart design look like to enable reply a reply?

• jQuery > reset popup window 's x and y relative to icon that launched the window

  - by Scott B

  I have a jQuery jPicker colorpicker that is bound to an input text field and opens onclick of a small picker.gif icon. The problem I'm having is that (1) The colorpicker that opens does not appear to be positioned according to the x/y position of the picker.gif (it opens far away from the click point) and (2) The colorpicker does not seem to be aware of the viewport's scroll position (the top of the colorpicker is partially hidden at the top of the window). I'd like to use jQuery to reposition the colorpalette (1) Based on the x/y position of the input that its bound to and (2) reset it's top position based on the viewport's visible Y position. Here is the script where I am creating a new jPicker and binding it to my input text fields for header and sidebar... $('#myHeaderColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } ); $('#mySidebarColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } );

• Validate a date range within MySQL query

  - by fishcracker

  (This question may seem easy or kind of noobish, by that I pardon my ignorance.) I used PDO query to use SELECT then fetch some values, it comes to a point that I need to fetch only some entries that within its start date and end date. My database +----------+-----------------+----------------------+--------------------+ | id (INT) | title (VARCHAR) | start_date (VARCHAR) | end_date (VARCHAR) | +----------+-----------------+----------------------+--------------------+ | 1 | buddy | 2012-11-26 | 2012-11-30 | | 2 | metro | 2012-12-05 | 2012-12-20 | | 3 | justin | 2012-11-28 | 2012-12-01 | +----------+-----------------+----------------------+--------------------+ My query is as follows: $query = "SELECT title, start_date, end_date FROM debts WHERE start_date >= CURDATE() AND end_date >= CURDATE()"; What I want to achieve is whenever the start_date is today or greater but not exceeding the end_date it will be valid. This will return the row for id 1, however if I change the start_date to 2012-11-25, it will fail due to the first condition on AND. I'm really confuse on this since I am new to this, is there any built-in function to handle this kind of situation?

• ReportViewer datadinding (WPF)

  - by user512150

  I have a rdlc file and I try to show it using report viewer control in WPF. My DataSource is called 'OfficeDataSet' and DataSet used in report is called 'Address'. I try to initialize report viewer (I put it in WindowsFormsHost) like this: private void PrepareReport() { reportDataSource = new ReportDataSource(); officeDataSet = new OfficeDataSet(); adapter = new AddressTableAdapter(); adapter.Fill(officeDataSet.Address); reportDataSource.Name = "OfficeDataSet_Address"; reportDataSource.Value = officeDataSet.Address; viewerInstance.LocalReport.DataSources.Add(reportDataSource); viewerInstance.LocalReport.ReportEmbeddedResource = "WpfApplication1.Reports.TestReport.rdlc"; viewerInstance.Location = new System.Drawing.Point(0, 0); viewerInstance.RefreshReport(); } but I got the message "A data source instance has not been supplied for the data source 'Address'". Anybody know what can be wrong with this code? (I'm totally new in WPF and Reporting Services).

• Custom business object comparer

  - by gruber

  Hello, I need to implement mechanism that compares two business objects and return the list of differences (past value, new value, isDifferenceBetter). Because not all fields of class has to be compared and one fields need to be compared with different function then the other (sometimes < is better sometimes is better ... ) I figured out that I need to implelemnt custom attribute and give it to each field that has to be compared in this object. This attribute must have: - name - delegate or sth to point to the function which would be applied for comparision (dont know how to do it so far) So could anyone suggest me if its a good idea? Maybe any other ideas. Using attributes I would be able to use refflection to iterate through each field with attribute and invoke needed delegate. thanks for help bye

• iTune redeem codes: limited to a single version?

  - by Big Papoo

  Hi, I'm wondering if V1.0 generated redeem codes will be usable on a V1.1 version of my app? BTW, I know redeem codes are valid only 4 weeks and I also know that apps downloaded with a redeem code can be upgraded for free as with paid ones. My concern here is just: do unused redeem codes become invalid when a new version of my app will be available on the store? Apple's doc is not clear about this point. Did someone experience this yet ? Thx. --GQ.
