  • Reading and decoding PDF-417 barcodes stored in an image or PDF file from within a .NET application

    - by John Rasch
    I am looking for a .NET library that is able to decode data from a PDF-417 barcode that is embedded either in an image file or PDF. At this point, I have only been able to find a Java version and a C version. Ideally, this library would be both open-source and free of charge, but I doubt such a decoder exists. I am open to trying out demos of existing products that you may have had experience with - which leads me to the question - have you had any experience reading PDF-417 barcodes embedded in images or PDFs using .NET, and which of the available products would you recommend to do so?

  • Organization moving from ASP.NET to WebLogic Portal - training recommendations?

    - by frankadelic
    My organization previously used ASP.NET for web projects. They are now migrating to WebLogic Portal/JEE for all future web projects. My experience as a Lead Developer / Architect is totally with .NET projects. I want to get ramped up on WebLogic/JEE, so I can contribute to future projects. Any training/certification suggestions for WebLogic/JEE, in a 6-month time frame? Assume that I will need to fund my own training, and I am working full time. So, money and time are limited.

  • Using WCF in .NET how can I make it auto generate SOAP docs like ASMX did?

    - by Hades
    I'm currently writing a web service using WCF in VB.NET. Previous web services I wrote used ASMX but I wanted to learn WCF and so far it's going well. I actually prefer the way WCF does things. One thing I miss however is the way that ASMX used to generate example SOAP requests and responses. It was like getting documentation for free. Is there anyway to auto generate SOAP documentation for WCF? If not, is there any way to generate it in a .NET page using the WSDL?

  • How many times can you randomly generate a GUID before you risk duplicates? (.NET)

    - by SLC
    Mathematically I suppose it's possible that even two random GUIDs generated using the built in method in the .NET framework are identical, but roughly how likely are they to clash if you generate hundreds or thousands? If you generated one for every copy of Windows in the world, would they clash? The reason I ask is because I have a program that creates a lot of objects, and destroys some too, and I am wondering about the likelihood of any of those objects (including the destroyed ones) having identical GUIDs.

  • Creating a Cocoa Framework

    - by David Schiefer
    Hi, I've created a working Cocoa framework which I wish to redistribute. The problem is however, it won't run outside of Xcode. I've read something about @executable_path/../Frameworks, which I did not include, because I don't know where to put it :/ Therefore I run my app in Xcode using the DYLD_FRAMEWORK_PATH variable which works fine, but only in Xcode - if I try to run it on its own it crashes straight away and says IMAGE NOT FOUND. I'm sure @executable_path/../Frameworks is what's missing, but I don't know where to put it. Could anyone help me out please? :) Thanks

  • How to persist non-trivial fields in Play Framework

    - by AlexR
    I am trying to persist complex objects using Ebeans in Play Framework (2.03). In particular, I've created a class that contains a field of type weka.classifier.Classifier (Weka is a popular machine learning library - see http://weka.sourceforge.net/doc/weka/classifiers/Classifier.html). Classifier implements Serializeable so I hoped that I can get away with something like @Entity @Table(name = "classifiers") public class ClassifierData extends Model { @Id public Long id; public Classifier classifier; } However, the Evolutions script suggests the following database structure: create table classifiers ( id bigint auto_increment not null, constraint pk_classifiers primary key (id)) ) In other words, it ignores the field of type Classifier. (The database is MySQL if it makes any difference) What should I do to store complex serializeable objects using Ebean/Evolutions/PlayFramework?

  • How to set the bounce address using System.Net.Mail?

    - by Anthony
    I'm trying to implement the Variable envelope return path (VERP) method to manage email addresses (ie when an email I send bounces back I want it to be sent to a specific email address so that I can update my database to avoid sending emails to that email address in the future). According to this article it is possible to specify the email address a bounce email is sent to. How do you do this in .Net? For example say I ([email protected]) want to send an email to you ([email protected]). If [email protected] doesn't exist anymore I want yourserver to send the bounce email to [email protected]). This way when I receive this bounced email I know that [email protected] is not a valid email address anymore and I can update my database accordingly. In this example, the bounce address would be: [email protected] How do you specify it using System.Net.Mail?

  • ASP.NET MVC v1 project upgraded to VS 2010 no longer will debug. Why?

    - by Todd Brooks
    I'm getting the message "The breakpoint will not currently be hit. No symbols have been loaded for this document." I have a S#arp Architecture project (ASP.NET MVC v1) that has been opened and upgraded to be used in VS 2010. I can no longer debug the project. I'm running Windows 7 Ultimate x64 and Visual Studio 2010 Ultimate. I have IE set to be my default browser. I have the build set to debug. System.Web.Mvc is referenced in my project's lib dir. I've cleaned the solution. I've recompiled the solution. It's set to use .NET Framework 3.5. PDBs are being created and dropped into the bin directory with the DLLs. Any help will be greatly appreciated.

  • Mobile Application Upgrade/Update Framework

    - by sharjeel
    I am developing a few mobile apps for different platforms including Blackberry, Windows Mobile, Android and Symbian S60. I want my mobile apps to have the capability of checking for updates before starting and in case a new version is available, prompt the user to upgrade. Moreover in certain cases (like security patches), the user must be forced to update or the app won't work. Surely I can cook some code to achieve the task but I was wondering if there are already existing framework to serve the purpose so that I don't have to re-invent the wheel and test all over?

  • Which PHP framework for a RoR developer?

    - by Horace Ho
    For one specific client I have to use PHP. This and this question were 2 years old. I'd like to know is there any update of opinion for year 2010? My background on web development is mainly rails. I can code in PHP (for example, write a module for Drupal) but never used any PHP framework for any project. I can see the following potential features to be needed in my project: authlogic-like user access control will_paginate-like paging for long listings paperclip-like simple file upload prawn-like PDF generation restful url and my personal favorite ruby/rails features: activerecord <% @list.each do |item| %> synstax instead of for ($i=1; $i<=$row_num; $i++) ... rake:db migrate script/console Thanks!

  • Correct redirect after posting comment - django comments framework

    - by Sachin
    I am using django comments framework for allowing users to comment on my site, but there is a problem with the url to which user is redirected after posting the comment. If I render my comment form as {% with comment.content_object.get_absolute_url as next %} {% render_comment_form for comment.content_object %} {% endwith %} Then the url to which it is redirected after the comment is posted is <comment.content_object.get_absolute_url/?c=<comment.id> For example I posted a comment on a post with url /post/256/a-new-post/ then the url to which I am redirected after posting the comment is /post/256/a-new-post/?c=99 where assume 99 is the id comment just posted. Instead what I want is something like this /post/256/a-new-post/#c99. Secondly when I do comment.get_absolute_url() I do not get the proper url instead I get a url like /comments/cr/58/14/#c99 and this link is broken. How can I get the correct url as mentioned in the documentation. Am i doing something wrong. Any help is appreciated.

  • What is the best approach to manipulate assets in Drupal from .Net application?

    - by Amandeep Singh
    I'm beginning work on a project that will access a Drupal site to create nodes on the site. This includes file uploading, as the project is to allow people to upload pictures en mass to a Drupal site with minimal ado. Note that my application is written in .Net. What I would like to know is the best approach to achieve the same? Based on initial research it looks like there are several options: 1. XML-RPC 2. Custom PHP module deployed in drupal. But, what is the way to invoke it from .Net? 3. Use a cron job to pick up the files from a watch folder. And add a cron_hook in my module to deploy the file.

  • "SQL Server does not exist or access denied." upon VB.Net Deployment

    - by JasonMHirst
    Have built a small VB.Net app in VS2010. The connection string to the SQL Server is as follows: <connectionStrings> <add name="IWSR_DataDownloadWizard.My.MySettings.sqlConnection" connectionString="Provider=SQLOLEDB.1;Data Source=SQLServer;Integrated Security=SSPI;Initial Catalog=IWSROL" providerName="System.Data.OleDb" /> </connectionStrings> Within the VS2010 environment AND on my machine, the connection works perfectly, however when I deploy to clients I get an error message of: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. I've tried to search the net for solutions, have seen a few instances of people saying to NOT use the Server Name but the IP Address instead (this doesn't work) and some saying to remove the "Provider=SQLOLEDB.1", again this doesn't work. Can anyone suggest a solution please? Further information: Development System is Windows7 using VS2010 Deployment systems are a combination of Windows XP, Windows 2000 and Windows 7 SQL Server is SQL2000 (soon to be SQL2005). TIA

  • Cross-platform SOA framework

    - by ByteMR
    I'm looking for a good cross-platform SOA framework that preferably works with several programming languages like C++, Python, and C#. I recently learned about Thrift, but that doesn't seem to work with MSVC from the documentation I've read and requires the use of Cygwin or MinGW to even compile the Thrift compiler. Does Thrift work with MSVC and if not, are there any alternatives that would meet my needs? Such as being able to generate C# and Python bindings and work on Linux, Mac, and Windows. Any suggestions would be greatly appreciated!

  • ASP.Net: User control with content area, it's clearly possible but I need some details.

    - by bert
    I have seen two suggestions for my original question about whether it is possible to define a content area inside a user control and there are some helpful suggestions i.e. http://stackoverflow.com/questions/1971498/passing-in-content-to-asp-net-user-control and http://stackoverflow.com/questions/1912283/asp-net-user-control-inner-content Now, I like the theory of the latter better than the former just for aesthetic reasons. It seems to make more sense to me but the example given uses two variables content and templateContent that the answerer has not defined in their example code. Without these details I have found that the example does not work. I guess they are properties of the control? Or some such? The former example seems workable but I'd prefer to go with the latter if someone could fill in the blanks for me. Thanks.

  • Rendering "partial" pages in ASP.Net? (without the <html> and such)

    - by Earlz
    Hello, I am trying to make use of jQueryUI AJAX tabs in my ASP.Net Webforms project. I have come up against a wall though. For AJAX, you must render only a partial page(no <html> and such elements) by an external URL. How would you best do this in ASP.Net? aspx files require things like a <html> and <head> tag so those wouldn't work so the only thing that comes to mind is using cumbersome ashx files. Am I just over thinking this? Is there an easier way?
