  • Write a MAT file without using matlab headers and libraries.

    - by YuppieNetworking
    Hello all, I have some data that I would like to save to a MAT file (version 4 or 5, or any version, for that matter). The catch: I wanted to do this without using matlab libraries, since this code will not necessary run in a machine with matlab. My program uses Java and C++, so any existing library in those languages that achieves this could help me out... I did some research but did not find anything in Java/C++. However, I found that scipy on python achieves this with mio4.py or mio5.py. I thought about implementing this on java or C++, but it seems a bit out of my time schedule. So the question is: is there any libraries in Java or C/C++ that permits saving MAT files without using Matlab libraries? Thanks a lot

  • Using Emacs for big big projects

    - by ignatius
    Hello, Maybe is a often repeated question here, but i can't find anything similar with the search. The point is that i like to use Emacs for my personal projects, usually very small applications using C or python, but i was wondering how to use it also for my work, in which we have project with about 10k files of source code, so is veeeery big (actually i am using source insight, that is very nice tool, but only for windows), questions are: Searching: Which is the most convenient way to search a string within the whole project? Navigating throught the function: I mean something like putting the cursor over a function, define, var, and going to the definition Refactoring Also if you have any experience with this and want to share your thoughts i will consider it highly interesting.

  • Switch to 64 bit or stay at 32 bit?

    - by Johnny
    I have a small office, and I currently use a Visual Foxpro Application that I wrote to handle all the data. It is time to buy a new server. It seems that there are problems with VFP and 64 bit operating system. Should I make the move to 64 bit and try to deal with the problems that arise, or buy a new server running the older 32 bit acrhitecture? The latter would of course require that I use Exchange 2003 instead of 2007 or 2008. Probably no big deal?

  • exception with Linq to SQL using sdf file

    - by Ben
    Hi, I've set up a project with an SDF local database file and am trying to access it using an LINQ To SQL (".dbml") file. I have used the connection string provided by the sdf file and can instanciate the object with out a problem: thisDataContext = new MyDataContext(GetConnectionString()); However, whenever i try to access any information from it eg var collection = (from MyObject p in thisDataContext.MyTable select p); I get the error - "The table name is not valid. [ Token line number (if known) = 2,Token line offset (if known) = 14,Table name = Person ]" I am using Visual Studio 2008 SP1 .Net 3.5 and SQL 2008 CE. I gather something similar happened for SQL 2005 CE and a Hotfix was released, but i would have thought the fix would have been fixed in this version before release. Does anyone know the fix for this? Thanks

  • [WPF C#]Get UserControl or VisualTree in DataValidation of TextBlock

    - by dalind
    Hy, I have a validator set on the text property of a textblock. For a correct validation I would need the parent usercontrol of the textblock, but the only things I have in the validator are the value object (a string) and the culture (doesn't help either). Does anyone know a way to get certain usercontrols in a class/a method where I have no access to any kind of visual or control of my application. The problem could be solve if I could give the validator the usercontrol or the textblock as parameters, but I didn't find a way to do so.. Thank you very much for your answers. Greets

  • How to create SSIS package to update from one database to another database within same server

    - by Pavan Kumar
    My query is related to the answers i got for questions i had posted earlier in the same forum. I have a copy of a client database which is attached to SQL Server where the Central Database exists. The copy already contains the updated data. I just want to update from that copy to Central Database both holding same schema and are present in the same server using C# .NET. One of the solution i got was to create SSIS package and run it from the UI. I want to know as how i can create SSIS Package to achieve this. I am new to SSIS. I am using SQL Server 2005 Standard Edition and Visual Studio 2008 SP1 installed. I learnt that BIDS 2005 is used to create packages which comes by default with SQL Server 2005. Can someone please give me a example as i am new to this.

  • How do I change the background color of the column with the expanders in Eclipse?

    - by Pridkett
    Recently after scorching my retinas from the garish white background in Eclipse, I found some of the excellent posts about how to change the colors so it uses sane (i.e. dark background) colors in the editor. However, one problem present in all solutions is that background of the column with the expanders for code folding is always white. Is there a way to change the background of that column? Here's a screenshot of the problem: I'm not the only person that has this problem, as shown in the screenshots for the following questions: Dark Color Scheme for Eclipse Color Themes for Eclipse (application of color schemes results in this issue on a Mac, no idea about PC) I know that the problem is not language specific as it happens in Java, Python, HTML, and everything else. Any hints on where in the pages of preferences this setting is?

  • Multidimensional arrays in VB.NET 2010

    - by matt_t
    Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python). Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case? e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]] Apologies for the poor explanation but I cannot think of any better ways to explain.

  • Is there a way to make sure a background process spawned by my program is killed when my process ter

    - by Davy8
    Basically the child process runs indefinitely until killed in the background, and I want to clean it up when my program terminates for any reason, i.e. via the Taskmanager. Currently I have a while (Process.GetProcessesByName("ParentProcess").Count() 0) loop and exit if the parent process isn't running, but it seems pretty brittle, and if I wanted it to work under debugger in Visual Studio I'd have to add "ParentProcess.vshost" or something. Is there any way to make sure that the child process end without requiring the child process to know about the parent process? I'd prefer a solution in managed code, but if there isn't one I can PInvoke. Edit: Passing the PID seems like a more robust solution, but for curiosity's sake, what if the child process was not my code but some exe that I have no control over? Is there a way to safeguard against possibly creating orphaned child processes?

  • CruiseControl failing view compilation with Asp.net MVC 2 RTM

    - by Robert Koritnik
    Tehnologies: - CruiseControlNet - Asp.net MVC 2 RTM - enabled view compilation The problem is UrlParameter.Optional setting. I can't seem to make it work when I use this setting inside a view. When I compile inside Visual Studio, everything works fine, but when CCNet uses MSBuild to compile it it fails with following error: errorCS0103: The name 'UrlParameter' does not exist in the current context pointing to the line inside my view where this parameter is set on: Html.RenderAction(...) that sets certain route parameter(s) to optional. I tried adding <%@ Assembly name="System.Web.Mvc" %> at the top of my view, but it didn't work either. It works of course when I disable view compilation, but that's not really an option. And I also don't want to set my optional parameters to string.Empty. Anyone has any hint on this?

  • Latent Dirichlet Allocation, pitfalls, tips and programs

    - by Gregg Lind
    I'm experimenting with Latent Dirichlet Allocation for topic disambiguation and assignment, and I'm looking for advice. Which program is the "best", where best is some combination of easiest to use, best prior estimation, fast How do I incorporate my intuitions about topicality. Let's say I think I know that some items in the corpus are really in the same category, like all articles by the same author. Can I add that into the analysis? Any unexpected pitfalls or tips I should know before embarking? I'd prefer is there are R or Python front ends for whatever program, but I expect (and accept) that I'll be dealing with C.

  • What advantages does TFS 2010 have over Axosoft OnTime?

    - by Russell
    I am currently creating a business case for rolling out TFS 2010 as our source control and bug/release management tool. We currently use OnTime for our bug tracking software and subversion for our SCM. I was wondering what advantages TFS 2010 has over OnTime? I have done some thinking so far and would love to hear responses: TFS 2010 allows linking changesets-work items-builds TFS 2010 provides greater customisation of workflow than OnTime TFS 2010 is integrated into the Visual Studio IDE - This requires less apps to be open and less window flicking Thanks in advance.

  • Is there anything RAD comparible to VCL?

    - by mawg
    After years in embedded programmking, I have to develop a windows app. I dug out my old C++ builder and Delphi. These are great and the latest version costs over $1k, so I won't be going there. What I prarticularly like is the VCL (visual component library) which let's me code my own components and share them with others, plus the thousands of existing 3rd party components. I noticed that there is now also a RAD PHP form Borland too. I realzie that MSVC, QT, NetBEans, etc are good enough IDEs for RAD, _BUT_ does anything offer the ease of the Borland products for developing additional components - and does anything else have thousands to choose from? PC based? Cross-platform is good. Browser based? Free is always good ;-) I don't particularly care about the programming language.

  • Converting Microsoft Word Smart Quotes to Straight Quotes

    - by curiousR
    We have a program where the user needs to do a Copy-Paste some content from Microsoft Word into a HTML editor (Visual Studio 2008). That content in the HTML is then used in our confirmation emails. Some of the characters like curly quotes turn into ? on the browser & in our confirmation email. For the browser... I was able to find how to resolve this issue by using jQuery. But for the confirmation email I cannot use JavaScript. I tried this ASP.net / C# code but it hasn't worked for me. if (s.IndexOf('\u201b') -1) s = s.Replace('\u201b', '\''); if (s.IndexOf('\u201c') -1) s = s.Replace('\u201c', '\"'); if (s.IndexOf('\u201d') -1) s = s.Replace('\u201d', '\"'); if (s.IndexOf('\u201e') -1) s = s.Replace('\u201e', '\"'); I would appreciate any help in resolution. Thanks.

  • What can i do about an ObjectDisposedException in a dll i cannot access?

    - by djerry
    Hey guys, I'm using a dll to monitor calls (Atapi.dll). Sometimes when events occur, there's an ObjectDisposedException. This seems to be random, i don't know what causes it. I can't debug it and i don't have the source code to it. The events that cause the exception are call events (conencting calls) through Tapi 2.0. It does not causes my app to crash. If i press on the continue button of the window visual studio is generating, the app continues ignoring the exception, but i'd rather not see it happening. I tried catching all code (not much) i have writting, but nothing catches it, and it also says i cannot debug it, because it is thrown in the dll. Does anyone have any idea how to solve or get pass this obstacle? Thanks in advance.

  • Windows Forms Autosizing in .NET

    - by mcoolbeth
    My C# project contains a form. There are some controls across the top of the form and some controls across the bottom of the form, as well as a FlowLayoutPanel in the center, all of which have been placed with the Visual Studio Form Designer. During runtime, controls are dynamically added to and removed from the FlowLayoutPanel, and both the panel and the form itself are configured to automatically fit the size of they're contents. However, since some controls were placed with the designer above and below the FlowLayoutPanel, the desired resizing fails to take place when new controls are added to the FlowLayoutPanel. Does anybody know of a convenient remedy for this problem?

  • How to debug .net error where message is masked in Ajax call

    - by Matt Thrower
    Hi, I'm currently working on a page which makes use of the MS Ajax UpdatePanel. However I've run into a strange problem. If I simply compile and view my page, one of the button click events results in an error. However, because the button affects items inside an UpdatePanel the actual exception is hidden from me: all I'm getting is a HTTP 500 error returned to me through the UpdatePanel Javascript. What's odd about this is that if I step through the code line by line in Visual Studio, I don't get the error. The button doesn't cause the behaviour I'm expecting, but it throws no errors. Because the step through isn't causing an error to be thrown, I'm at a loss how I can get to the actual exception message so I can find out where the error is being thrown and debug it. Suggestions gratefully received. Cheers, Matt

  • Ruby from the command line - sticking - Windows

    - by tyndall
    I have seen this behavior on Windows with Ruby for a long time. If I install a gem sometimes the command line will just get "lost" and stop printing output until you go back to the command line and hit enter a few times. I notice this in other places too. Like starting up a Ruby on Rails console. Or generating a model with Rails. Have other people seen this? What causes this? The weird thing is this doesn't happen all the time. I have never seen this with PHP, Lua, Perl or Python from the command line. I have seen this on Vista and Windows 7 (32-bit and 64-bit). This happens on multiple machines.

  • What is the best XPS WYSIWYG Editor that will output XAML?

    - by Simon
    I am looking for a WYSIWYG for XPS that will ouput the raw XAML. My intentions is use the tool for a way to quickly generate and test the XAML (of XPS documents) with the intention of then generating the same xaml in code and programmatically generating an XPS document. The same approach that many people use for generating html. Can anyone recommend any of the below products or suggest any others? Better yet does anyone know of a free XPS editor? NiXPS Edit $300USD http://www.nixps.com/nixps_edit_20.html XamlPad is free but also quite limited and does not really target XPS. Office System Power Tools is not WYSIWYG http://blogs.msdn.com/adrianford/archive/2008/07/03/visual-studio-and-xps-files.aspx XPS eXaminer 1.0 $399USD http://storefront.qualitylogic.com/p-16-qualitylogic-xps-examiner.aspx

  • Extracting dates from html meta data in FAST-ESP

    - by Neil
    During document processing I want to extract all dates from html meta data and then identify the latest date which will be used to populate a date field (dtgeneric1). <meta name="OriginalPublicationDate" content="2010/04/21 12:06:36" /> <meta name="LastModificationDate" content="2010/04/22 14:10:16" /> + other non-date meta data Inspection using spy stages shows that our pipeline already adds meta_* attributes but the meta data names will be different across documents from different sources. #### ATTRIBUTE meta_originalpublicationdate <class 'docproc.DocumentAttributes.TextChunks'>: 2010/04/21 12:06:36 #### ATTRIBUTE meta_lastmodificationdate <class 'docproc.DocumentAttributes.TextChunks'>: 2010/04/22 14:10:16 + other non-date meta attributes Ideally we would like to pass all the meta_* attributes to a Python stage and use that to work out which are dates and which is the largest but there seems to be no way of specifying "all meta attributes" as input. Has anyone done something similar and can offer any advice on the best way to do this. Thanks Neil

  • entity framework, loadproperty not working - The selector expression for LoadProperty must be a Memb

    - by SLC
    The selector expression for LoadProperty must be a MemberAccess for the property. I'm converting some C# to VB, this is the C# line: entities.LoadProperty((MyType)MyTargetObject, c => c.MyProperty); I convert it to VB like so: entities.LoadProperty(DirectCast(MyTargetObject, MyType), Function(c) c.MyProperty) However I get the error above. I don't understand what the code is doing, or anything at all, I am simply converting it line by line into Visual Basic. When I run the project, the error I get is the one above. All I can see is that Entities is a class that inherits ObjectContext, which might mean something. Any help would be soooo good because I am stressing out big time. Thanks.

  • How to use Cassandra's Map Reduce with or w/o Pig?

    - by UltimateBrent
    Can someone explain how MapReduce works with Cassandra .6? I've read through the word count example, but I don't quite follow what's happening on the Cassandra end vs. the "client" end. https://svn.apache.org/repos/asf/cassandra/trunk/contrib/word_count/ For instance, let's say I'm using Python and Pycassa, how would I load in a new map reduce function, and then call it? Does my map reduce function have to be java that's installed on the cassandra server? If so, how do I call it from Pycassa? There's also mention of Pig making this all easier, but I'm a complete Hadoop noob, so that didn't really help. Your answer can use Thrift or whatever, I just mentioned Pycassa to denote the client side. I'm just trying to understand the difference between what runs in the Cassandra cluster vs. the actual server making the requests.
