  • mapping 'value object' collection in (Fluent) NHibernate

    - by adrin
    I have the following entity public class Employee { public virtual int Id {get;set;} public virtual ISet<Hour> XboxBreakHours{get;set} public virtual ISet<Hour> CoffeeBreakHours {get;set} } public class Hour { public DateTime Time {get;set;} } (What I want to do here is store information that employee A plays Xbox everyday let's say at 9:00 13:30 and has a coffee break everyday at 7:00 12:30 18:00) - I am not sure if my approach is valid at all here. The question is how should my (ideally fluent) mappings look like here? It is not necessary (from my point of view) for Hour class to have Id or be accessible from some kind of repository.

  • 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>

  • Referencing control on one form from another form VB.NET

    - by Tom
    My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

  • Loop with pointer arithmetic refuse to stay within boundary in C. Gives me segfault.

    - by Fred
    Hi have made this function which is made to replicate an error that I can't get past. It looks like this: void enumerate(double *c, int size){ while(c < &c[size]){ printf("%lf\n", *c); c++; } } I have added some printf's in there and it gives me: Adressof c: 0x100100080, Adressof c + size: 0x1001000a8 I then also print the address of c for each iteration of the loop, it reaches 0x1001000a8 but continues past this point even though the condition should be false as far as I can tell until I get a segfault. If anyone can spot the problem, please tell me, I have been staring at this for a while now. Thanks.

  • How to partition a plane

    - by puls200
    Let's say I have a fixed number (X) of points, e.g. coordinates within a given plane (I think you can call it a 2-D point cloud). These points should be partitioned into Y polygons where Y < X. The polygons should not overlap. It would be wonderful if the polygons were konvex (like a Voronoi diagram). Imagine it like locations forming countries. For example, I have 12 points and want to create 3 polygons with 4 points each. I thought about creating a grid which covers the points. Then iterate across the points, assigning them to the closest grid cells. Maybe I miss the obvious? I am sure there are better solutions. Thanks, Daniel I just found an optimization (kmeans++) .Maybe this will yield better results..

  • 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.

  • Attach 1 or more (non image) files to rails application, with having to install an image-processing

    - by Hinchy
    Hi all, I'm currently learning rails by creating a simple project management app. I've gotten to the point where I would like to be allow a user upload multiple files - pdfs, docs, xls etc. The user only needs to be able to attach one file at a time, but the possibilty to have multiple documents associated with a project is a must. I've spent quite a lot of time researching my options, and it appears the two main plugins are attachment_fu and paperclip. From what I've read though, these appear to concentrate specifically on the upload and subsequent resizing of images, something I couldn't care less about. Is there a simpler way to achieve what I'm trying? Thank you all in advance.

  • Assorted list of what's new in Delphi [Language, RTL, VCL]?

    - by utku_karatas
    Hi gents, As someone who's been stuck at the older versions of Delphi and upgraded to D2010 lately, I figure I still use the language, RTL and VCL features from the D5 era and refrain from using these new features as the documents on those are somewhat decentralized around the blogosphere. So I'd like to ask if there was an assorted list like what's new docs of Python's - clear and concise to the point. Btw, please no screencasts. They seem to be quite abundant lately (probably because of CodeRages) but I find them very unintuitive to learn from. Let's leave that docs in video format thing to RoR community, shall we :).

  • Trouble creating a makefile

    - by catia
    Hi everyone! I'm having some trouble making a Makefile. Write now I just compile everything every time. Although, the professor is ok with that, I do want to get it working faster and to avoid unnecessary compiling. Here's what I have. FILES= p6.cpp SetIter.cpp Node.cpp Set.cpp CFLAGS= -ansi -pendantic -Wall -Wextra CC= g++ MakePg6: p6.cpp SetIter.cpp Node.cpp Set.cpp $(CC) $(CFLAGS) $(FILES) -o pg6 Node.cpp - node class Set.cpp - uses nodes. Friend of Node. SetIter.cpp - gets a set and uses a pointer to iterator through I'm confused with some of the depencies arising from the friends thing and the point of lib.o being included in the Makefile as some sites have. Any help is greatly appreciated. Thanks in advance.

  • Selecting Element followed by text with Selenium WebDriver

    - by Andrew
    I am using Selenium WebDriver and the Python bindings to automate some monotonous WordPress tasks, and it has been pretty straightforward up until this point. I am trying to select a checkbox, but the only way that I can identify it is by the text following it. Here is the relevant portion of HTML: <li id="product_cat-52"> <label class="selectit"> <input value="52" type="checkbox" name="tax_input[product_cat][]" id="in-product_cat-52"> polishpottery </label> </li> The only information that I have in my script to identify this checkbox is the string "polishpottery". Is there any way to select that checkbox knowing only the text that follows?

  • 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?

  • Trouble understanding Java map Entry sets

    - by Jake Sellers
    I'm looking at a java hangman game here: https://github.com/leleah/EvilHangman/blob/master/EvilHangman.java The code in particular is this: Iterator<Entry<List<Integer>, Set<String>>> k = partitions.entrySet().iterator(); while (k.hasNext()) { Entry<?, ?> pair = (Entry<?, ?>)k.next(); int sizeOfSet = ((Set<String>)pair.getValue()).size(); if (sizeOfSet > biggestPartitionSize) { biggestPartitionSize = sizeOfSet; } } Now my question. My google foo is weak I guess, I cannot find much on Entry sets other than the java doc itself. Is is just a temporary copy of the map? And I cannot find any info at all on the syntax: Entry<?, ?> Can anyone explain or point me toward an explanation of what is going on with those question marks? Thanks in advanced.

  • 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

  • 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?

  • 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?

  • How to change the app name in OSX menubar in a pure-Python application bundle?

    - by gyim
    I am trying to create a pure-Python application bundle for a wxPython app. I created the .app directory with the files described in Apple docs, with an Info.plist file etc. The only difference between a "normal" app and this bundle is that the entry point (CFBundleExecutable) is a script which starts with the following line: #!/usr/bin/env python2.5 Everything works fine except that the application name in the OSX menubar is still "Python" although I have set the CFBundleName in Info.plist (I copied the result of py2app, actually). The full Info.plist can be viewed here: http://tinyurl.com/32qgpjt How can I change this? I have read everywhere that the menubar name is only determined by CFBundleName. How is it possible that the Python interpreter can change this in runtime? Note: I was using py2app before, but the result was too large (50 MB instead of the current 100KB) and it was not even portable between Leopard and Snow Leopard... so it seems to be much easier to create a pure-Python app bundle "by hand" than transforming the output of py2app.

  • 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.

  • 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.

  • 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.

  • 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?

    Hi all I have written a MVVM prototype as a learning exercise and I am struggling to understand how I can communicate between views.Let me explain I have a treeview on the left (leftSideView) ListView on the right (rightSideView) MainWindow (includes the 2 views mentioned above and a splitter) What I have implemented does not work and I would like you if you can point out where I am going wrong or if there is a better way of doing it. you can download the quick prototype from here http://cid-9db5ae91a2948485.skydrive.live.com/self.aspx/.Public/WpfCommunicationBetweenViews.zip For sure I am doing something wrong with the bindind. Also it would be nice to learn how you do it. EG ListBox on left (one view) ListView On the right (another view) how u communicate between the two. Thanks a lot of any suggestions

  • 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.
