  • How do I copy security information when creating a new folder?

    - by dhh
    In my app I'm creating folders for archiving old stuff from a harddisc. When creating a new folder I must copy all NTFS rights (Groups / Users) from the source folder to the newly created destination folder. Here is what I've written so far: FileSecurity fileSecurity = File.GetAccessControl(filenameSource, AccessControlSections.All); FileAttributes fileAttributes = File.GetAttributes(filenameSource); File.SetAccessControl(filenameDest, fileSecurity); File.SetAttributes(filenameDest, fileAttributes); Is this really all I ought to do or am I missing something important?

  • How to determine pixel color of System.Windows.Controls.Image?

    - by csciguy
    I have an Image from (System.Windows.Controls.Image). This image is positioned on a main canvas. I want to determine the alpha channel value of the mouse cursor when I click on any portion of this image. When doing something like the following, I'm getting an exception. {"Value does not fall within the expected range."} System.Exception {System.ArgumentException} Code: try{ CroppedBitmap cb = new CroppedBitmap(ac.displayImage.Source as BitmapSource, new Int32Rect((int)mousePoint.X, (int)mousePoint.Y, 1, 1)); byte[] pixels = new byte[4]; cb.CopyPixels(pixels, 4, 0); } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.Message); } The mousePoint.X, and mousePoint.Y are obtained when the user clicks on the main window. Is there a better way to do this?

  • Data mining logs to locate a bug

    - by gooli
    I'm working on a data distribution application which receives data from a source and distributes that data to multiple target application. After successfully distributing several messages each second for 8 days, it missed a single message and did not deliver it properly to the clients. As I was looking at the logs I tried to find something there that was special for the time the miss happend - either in the data, its rate or some other condition but couldn't find anything. Is there any data mining technique I can use to identify how that specific event differs from other events?

  • Using Apache Velocity with StringBuilders/CharSequences

    - by mindas
    We are using Apache Velocity for dynamic templates. At the moment Velocity has following methods for evaluation/replacing: public static boolean evaluate(Context context, Writer writer, String logTag, Reader reader) public static boolean evaluate(Context context, Writer out, String logTag, String instring) We use these methods by providing StringWriter to write evaluation results. Our incoming data is coming in StringBuilder format so we use StringBuilder.toString and feed it as instring. The problem is that our templates are fairly large (can be megabytes, tens of Ms on rare cases), replacements occur very frequently and each replacement operation triples the amount of required memory (incoming data + StringBuilder.toString() which creates a new copy + outgoing data). I was wondering if there is a way to improve this. E.g. if I could find a way to provide a Reader and Writer on top of same StringBuilder instance that only uses extra memory for in/out differences, would that be a good approach? Has anybody done anything similar and could share any source for such a class? Or maybe there any better solutions to given problem?

  • deriving activity diagram-based GUIs and CRUD them with a DB?

    - by Xin Tanaka
    i received a big book full of processes. i was thinking about the end user (they will be lawyers) and decided the best GUI would be showing activity diagrams or business processes. It reminded me Quickbooks and how non-accountants can successfully use it and understand accounting processes. i began doing research before sending my project to a bunch of programmers: is there some open source solution? can i use MS Visio libraries? which UML tool is programable? what about Eclipse and its modeling tools? etc etc the key points here are: relationships between events, artifacts, actors, etc should be stored in a database. processes or steps in a process should be easily modified by updating the database do this sounds too crazy? (should I explain a bit more why it must be programmed this way?)

  • Graph diffing and versioning tool

    - by hashable
    I am working with a team that edits large DAGs represented as single files. Currently we are unable to work with multiple users concurrently modifying the DAG. Is there a tool (somewhat like the Eclipse SVN plugin) that can do do revision control on the file (manage timestamps/revision stamps) to identify incoming/outgoing/conflicting changes (Node/Link insertion/deletion/modification) and merge changes just like programmers do with source code files? The system should be able to do dependency management also. E.g. an incoming Link must not be accepted when one of the two Nodes is absent. That is, it should not "break" the existing DAG by allowing partial updates. If there is a framework to do this using generic "Node" and "Link" interfaces? Note: I am aware of Protege and its plugins. They currently do not satisfy my requirements.

  • the best "Simple" CMS system suitable for .Net MVC

    - by Truegilly
    Hello, I'm developing a MVC .Net site and would like to implement a CMS system. So far I have looked at Umbraco, which looks good but the help is poor and the getting started video section is empty, and dotnetnuke, which again looks good but I get the impression its aimed at non developers, plus to has much more than I need and want. In my last job I created a basic custom CMS system that worked by simply adding values into the database, the application called the text from there. it worked fine but I don’t have the source code. what I'm after is a simple CMS system that really just controls text and images, I dont need all the fancy stuff thats in umbraco and dotnetnuke, all the design and CSS i can do myself. also as im working with MVC (which is awesome, and such a breath of fresh air compared to the web forms/telerik crap I have to put up with at work) it needs to be compatible. A simple CMS, can anyone provide any suggestion ? Truegilly

  • How to programmatically set a data cell of database in VB.Net?

    - by manuel
    I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = textbox.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Low". What codes should I put in the button_Click event handler? Here is the codes I used to retrieve and display the database table. Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub

  • Changing folder names in Visual Studio when using SVN

    - by Piers Myers
    I am using VS2008/VS2010 with Resharper 5, TortoiseSVN 1.6.8.19260-x64, and AnkhSVN 2.1.8420.8. Most operations I do in Visual Studio are reflected fine in SVN, however, renaming folders in a project can cause problems when I try to submit my changes. Also all the namespaces in the C# source files under the renamed folder need to be updated to reflect the name change. What is the best way to rename the main project folder or any sub folders and ensure there are no issues with SVN? Should it be done outside Visual Studio? What is the best way to update all the namespace changes? Is search/replace the only way? Are there any best practices regarding folder names and their contents?

  • JSON documents and SQL database tables

    - by Sharmi
    Do JSON documents in RavenDB cost more than the SQL Server tables in terms of the storage and query costs. And also for centralized access, which one is better? What are the disadvantages of NON-SQL databases like RavenDB,CouchDB,MongoDB, etc... ? I can get that some of these are open source and support more datatypes like enums,objects,etc. but otherwise i don't see any big advantage? Currently there is a problem of storing huge amount of logs from various locations. I am planning to suggest these to my manager so just need a clear idea.

  • How to catch specific exception without error number?

    - by CJ7
    I need to catch the following specific exception: System.Data.OleDb.OleDbException was caught ErrorCode=-2147467259 Message="The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again." Source="Microsoft JET Database Engine" I'm not sure what ErrorCode is but it looks unreliable. Can I rely on Message being identical across platforms? Is the only solution to do a text search of Message for words like duplicate and primary key? Note: see my question here for why I need to catch this exception.

  • Can't see or add Website Data Sources in RDLC report in ASP.NET MVC

    - by RobertC
    In the RDLC report, in Design view in Visual Studio 2008, we don't see anything in the Website Data Sources tab and the button to Add New Data Source is grayed out. Only the Refresh button is enabled, and clicking it doesn't do anything. Our business logic layer returns Lists of business objects and the business logic and business object projects are both referenced by the MVC project. This is an MVC app, so there is no App_Code folder. How do we get our business objects to appear in the Website Data Sources list so we can drag and drop fields from the object onto our RDLC report?

  • is there some PHP social crm, plugins, or frameworks?

    - by garcon1986
    Hello, What i need to do: I'm trying to realize social networking graph for companies, employees in CRM. They could have many complex relationships. A company can have its network like inverstors, partners, competitors and customers etc. I want to realize a dynamic social networking graph for it. And it has to be implemented by php. Right now, i know SugarCRM and vTigerCRM are php open source CRMs. And SugarCRM provides some social functions. And there are a lot of other CRMs, while i'm not sure if they are realized by php, such as: ACT!, Microsoft Dynamics, Oracle Siebel Social CRM, Salesforce, BatchBlue, Buzzient etc. Do you know any other php CRMs, especially php social CRMs? Thanks

  • Flash uploader that can handle >2GB files?

    - by Alvin SMith
    Is there an open source Flash uploader that can handle files larger than 2 GB? ASP.net implementations like SlickUpload are not an option, and SWFUpload (and others that I've seen) do not handle files larger than 2 GB. Nor is requiring the user to have Java installed to run applets. This would be for both IE and Firefox. I've seen a couple "large file transfer" sites that have a Flash uploader and claim to go past the 2GB limit (which is the limit for http uploads for most browsers) so I know it is technically possible.

  • Silverlight MergedDictionaries and subclassing of Application

    - by mikeymo
    We have subclassed the Silverlight Application class to add some additional functionality and then use this in multiple projects. The problem is that the Resources defined in App.xaml do not seem to get loaded. Has anyone else seen this and/or have some insight? Here are the contents of App.xaml (note: the application starts and runs fine but then chokes when it looks for a Resource) <myNS:ApplicationBase xmlns:myNS="clr-namespace:Corp.XYZ.Infrastructure.Silverlight.Core;assembly=Corp.XYZ.Infrastructure.Silverlight.Core" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Corp.XYZ.BMW.App" > <myNS:ApplicationBase.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources/AlternateControlStyles/StandardExpander.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </myNS:ApplicationBase.Resources>

  • Easy way to parse a url in C++ cross platform?

    - by Andrew Bucknell
    I need to parse a url to get the protocol host path and query in an application I am writing in c++. The application is intended to be cross platform. Im surprised I cant find anything that does this in boost or poco libraries. Is it somewhere obvious Im not looking? Any suggestions on appropriate open source libs? Or is this something I just have to do my self? Its not super complicated but it seems such a common task I am surprised there isnt a common solution.

  • How do you implement syntax highlighting?

    - by ML
    I am embarking on some learning and I want to write my own syntax highlighting for files in C++. Can anyone give me ideas on how to go about doing this? To me it seems that when a file is opened: It would need to be parsed and decided what type of source file it is. Trusting the extension might not be fool-proof A way to know what keywords/commands apply to what language A way to decide what color each keyword/command gets I want to do this on OS X, using C++ or Objective-C. Can anyone provide pointers on how I might get started with this?

  • shall I move from prototype to jquery?

    - by opensas
    lastly I've been feeling like jquery is slowly becoming the defacto standard in js libraries I might be wrong!) or at least that is more active than the rest of the frameworks... for example I've been looking for a fine open source calendar like componente and found http://fullcalendar.vinsol.com/ we've been using prototype for very little things, like its selector capabilities ($ function as a shortcut for document.getElementById, mainly), executing some piece of js when the page is loaded and to issue some very simple ajax calls. so I guess the migration should be quite straight forward, but I'd like to know the pros / cons of migrating to prototype... on the other hand, I guess that having both of them together is not a good choice, specially taking into account that the migration should be quite simple... am I right? saludos sas
