  • OOP design for DMS that allows searching and grouping

    - by James P.
    I'd like to make a searchable Document Management System and allow a user to group documents together. On one hand, there would be a functionality that registers/fingerprints in a linear fashion and, on the other, one that associates documents into groups. How could I compromise between the two in terms of object design?

    - by Someone
    In a system with both ends (client and server) in .NET, is it possible to use the binary serialization provided by the dataset class in ADO.NET 2.0 when the datasets are exposed as WebMethods parameters ? Is it ok to use something like the following just before the dataset is returned: someDataSet.RemotingFormat = SerializationFormat.Binary;

  • What the purpose/difference in using an event-type constructor

    - by phq
    In all examples I can find as well as the automatically generated code i Visual Studio, events are set using the following code: button1.Click += new System.EventHandler(this.button1_Click); But I can also write it visually cleaner by omitting the constructor wrapper: button1.Click += this.button1_Click; Which also compile fine. What is the difference between these two? And why is the first one mostly used/preferred?

  • License plate recognition

    - by WowtaH
    As a side-project I'm trying to create an app that scans license plates from passing cars from my living-room window. I have hooked up a high resolution camera to my system to capture (moving) images into my c# app. Now all I need is a way to interpret these images into something readable. I´m thinking about some sort of OCR-solution that is fast/accurate enough for moving images. Hope you can give me some direction!

  • Delphi To Java code conversion: image.canvas.pixels

    - by Mattl
    I'm trying to convert an old Delphi program I wrote into Java to compile and run on my Android phone. I'm running the Android 2.1 operating system but am using version 1.6 of the SDK. I have a routine in Delphi where I set the colour of pixels on a canvas individually along the lines of: image1.canvas.pixels[x, y] := GetMyTColor(x, y); Is there a Java equivalent to the property on the Canvas: property Pixels[X, Y: Integer]: TColor

  • Boost Serialization Library upgrade

    - by Konstantin
    Hello! How do I know that I can safely upgrade Boost Serialization Library on a production system without breaking compatibility with the existing data ? Is there any test that I should perform in order to be sure that all data stored in the binary format by previous version of the library will be successfully read by the new one ? Does Boost Serialization library itself guarantee some sort of compatibility between versions ?

    - by Henry Jackson
    I'm developing an in-house .NET application that will be run on a VM (with VMware), and want to know if there's a way to get notifications from VM system events (like suspending, resumed, etc.) Anyone know of a convenient way to do that? The virtual machine has VMware Tools installed, does that provide a .NET API for hooking events?

    Hi, I had installed a new IIS7 on a Win2008.

No tiene permiso para ver este directorio o esta página con las credenciales que ha proporcionando. The IIS user had full permission in the fily system and on the IIS. Have anyone an idea why this could be happening? Thanks

  • Hadoop write directory

    - by FaultyJuggler
    Simple question but reading through documentation and configuration I can't quite seem to figure it out. How do I A) know where hadoop is writing to on the local disk and B) change that For initial testing I setup HDFS on a 20gb linux VM - to it we've added a 500gb networked drive for moving towards prototyping the full system. So now how do I point HDFS at that drive, or do I simply move the home directory/install with some slight change in setup and restart the process?

  • Alternatives to Ctags/Cscope with Objective-c?

    - by esiegel
    Are there any alternatives to ctags and cscope with Objective-c support. This does pertain to cocoa development, so inevitably it seems I will be using Xcode (and probably should). I was just wondering what are my Vim options. Maybe there is some type of plugin system like eclim, but for xcode? EDIT So it seems that other than updating ctags to support objective-c, I'm out of luck. Does anyone know if cscope is the same?

  • SQL Server and Identity column

    - by andrew007
    Hi, I just noticed that if I have an identity column in a table, when I insert new rows SQL Server 2008 is automatically filling up the sequence if there are discontinuity. I mean, if in my identity column I have 1,2,5,6 if I insert other two rows in the table the system puts automatically 3,7 in the identity column. Do you know how to control this behavior? THANKS

    After adding log4j to my application I get the following output every time I execute my application: log4j:WARN No appenders could be found for logger (slideselector.facedata.FaceDataParser). log4j:WARN Please initialize the log4j system properly. It seems this means a configuration file is missing. Where should this config file be located and what is a good start content? I'm using plain java for developing a desktop application. So no webserver etc...

  • [WPF] Is D3DImage causing airspace problem?

    - by Crocodile
    A DirectX scene can be drawn inside of a WindowsFormsHost, but this solution concerns struggling with some interop issues, mainly the 'airspace' problem. Thus, before creating whole framework for this, I'd like to know, if a D3DImage used within a WPF window will cause alike problems with overlay and sizing as described in the WindowsFormsHost doc? Or is it designed to be fully compatible with WPF system? Thank you for your help.

  • What video encoder services do you use with s3?

    - by Trip
    We were using FFmpeg which is free. And when a bug occurred that broke the system, a previous developer installed PandaStream. My question is, what do you recommend for quality video encoders? Is it best to stick with ffmpeg and keep it free, or does a small website really need a heavy duty service like Panda?

  • Make a final call to the Database when user leaves website (ASPX)?

    - by Jisaak
    I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?
