  • An existing connection was forcibly closed by the remote host

    - by Alexander
    I am about to give up debugging SMTP servers to send email... My code is the following private void SendMail() { SmtpClient mailClient = new SmtpClient("smtp.mail.yahoo.com", 465); mailClient.EnableSsl = true; MailMessage message = new MailMessage(); message.To.Add("[email protected]"); message.Subject = "i wish it would work"; MailAddress fromAddress = new MailAddress(Email.Text, Name.Text); message.From = fromAddress; mailClient.Send(message); }

  • C#, MEF - Sign trusted plugins for abuse reduction

    - by Marks
    Hi there. I have a program that is extendable by plugins using the Microsoft Extensibility Framework. But i dont want untrusted sources to give out plugins that may be insecure. So i want to sign the plugins (maybe with Visual Studio's built in signing) and check if the plugins are trustworthy at program start. I didn't find a way to check DLL signing from inside C#. And also there is the problem, that I load the plugins with a DirectoryCatalog. There is no way to tell, which plugin is from which file. Anyone knows a way to do this? Thanks for any help, Marks

  • Tips on how to deploy C++ code to work every where

    - by User1
    I'm not talking about making portable code. This is more a question of distribution. I have a medium-sized project. It has several dependencies on common libraries (eg openssl, zlib, etc). It compiles fine on my machine and now it's time to give it to the world. Essentially build engineering at its finest. I want to make installers for Windows, Linux, MacOSX, etc. I want to make a downloadable tar ball that will make the code work with a ./configure and a make (probably via autoconf). It would be icing on the cake to have a make option that would build the installers..maybe even cross-compile so a Windows installer could be built in Linux. What is the best strategy? Where can I expect to spend the most time? Should the prime focus be autoconf or are there other tools that can help?

  • Sort database entries via a dropdown list

    - by Lin
    Hello! I'm curious if anyone could possibly help me, because I can't find anything exactly related to it anywhere, and it's driving me nuts. I'd like to have a dropdown list on a page, that will give the visitor the option to sort all entries by year. I have entries from i.e. 2001, 2005, 2009, 2010. The years should be displayed in the dropdown, so the visitor can easily just select all entries dated 2001 if they want. The year for each entry is located in the one database table I have. In other words, I simply want a "sort by" dropdown that you can see on pretty much any shopping site nowadays. But with set years. Thanks in advance for any replies!

  • Building a service for a Drupal site to duplicate a node to another Drupal site in a multi-site setu

    - by EricP
    I'm trying to set up one of my Drupal sites to push a node to another Drupal site in a multi-site configuration. It looks like I need to do this with services somehow, but I can't find any tutorials out there and I need at least to be pointed in the right direction. What I believe I need is set up Services on the receiving site to accept a call from the sending site which will be sending the node object via Json or serialized PHP using a Key that was set up on the receiving site. Can anyone show me an example of this working or give me some insight? thanks

  • Google Search API - Only returning 4 results

    - by user353829
    After much experimenting and googling, the following Python code successfully calls Google's Search APi - but only returns 4 results: after reading the Google Search API docs, I thought the 'start=' would return additional results: but this not happen. Can anyone give pointers? Thanks. Python code: /usr/bin/python import urllib import simplejson query = urllib.urlencode({'q' : 'site:example.com'}) url = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&%s&start=50' \ % (query) search_results = urllib.urlopen(url) json = simplejson.loads(search_results.read()) results = json['responseData']['results'] for i in results: print i['title'] + ": " + i['url']

  • PgJDBC: "no suitable driver found" when following tutorial, why?

    - by Celeritas
    I'm writing a Java program that queries a PostgreSQL database. I'm following this example and have trouble here: connection = DriverManager.getConnection( "jdbc:postgresql://127.0.0.1:5432/testdb", "mkyong", "123456"); According to the JavaDoc for DriverManager the first string is "a database url of the form jdbc:subprotocol:subname. When I connect to the server I type in psql -h dataserv.abc.company.com -d app -U emp24 and give the password qwe123 (for example sake). What should the first argument of getConnection be? I've tried connection = DriverManager.getConnection( "jdbc:postgresql://dataserv.abc.company.com", "emp24", "qwe123"); and get the run time error: no suitable driver found. I've download JDBC4 Postgresql Driver, Version 9.2-1000.

  • Processing variable number of form fields

    - by a_m0d
    I am working on a form which displays information about orders. Each order has a unique id, but they are not necessarily sequential on the form. Also, the number of fields can vary (one field per row on the form). The input into the form will not be mapped straight into the database, but will be added to the current value in the database, and then saved. An example of the form is in the picture below - the callout on the right shows the id for each row. I know how to generate the form like this, but I can't work out how I can easily process each of these rows reliably. I also know how to give each of the fields a unique identifier, like name="row-23", but how can I translate that name so that I can update the related record in the database?

  • How to double the size of 8x8 Grid whilst keeping the relative position of certain tiles intact?

    - by ke3pup
    Hi guys I have grid size of size 8x8 , total of 64 Tiles. i'm using this Grid to implement java search algorithms such as BFS and DFS. The Grid has given forbidden Tiles (meaning they can't be traversed or be neighbour of any other tile) and Goal and Start tile. for example Tile 19,20,21,22 and 35, 39 are forbidden and 14 an 43 are the Goal and start node when the program runs. My question is , How can i double the size of the grid, to 16x16 whilst keeping the Relative position of forbidden tiles as well as the Relative position of start and goal Tiles intact? On paper i know i can do this by adding 4 rows and columns to all size but in coding terms i don't know how to make it work? Can someone please give any sort of hints?

  • Why is it a bad idea to use ClientLogin for web apps in the Google API?

    - by Onema
    I just picked up the Google API today to allow some users of our site to upload videos to our own organization YouTube account. I Don't want our users to know our user name and password, but rather give them the option if they want to upload videos to youtube or not. If they choose to do it, they check on a check box and hit the submit button. I keep seeing over, and over in the Developers guide that ClientLogin, which to me looks like the best option to implement what I want to do, is not a good idea for user authentication in web applicaitons. The "AuthSub for web applications" doesn't seem to be the best mechanism for what I want to implement! Any ideas on what to do? Thank you

  • Open source LINQ search engine for website

    - by Noel
    I want to add a search engine to my website. I want it to handler boolean searches and give me a list of results in order or best match. I need it to be able to work with LINQ, because I want to add additional where clauses to the final query that gets run. I am looking for the best open source .NET search engine that works with LINQ. I like lucene.net but the problem is the LINQ interface (LINQ to Lucene) hasn't been updated since 2008. Are there any good options out there?

  • Initialising structs in C++

    - by Neil Butterworth
    As an addendum to this question, what is going on here: #include <string> using namespace std; struct A { string s; }; int main() { A a = {0}; } Obviously, you can't set a std::string to zero. Can someone provide an explanation (backed with references to the C++ Standard, please) about what is actually supposed to happen here? And then explain for example): int main() { A a = {42}; } Are either of these well-defined? Once again an embarrassing question for me - I always give my structs constructors, so the issue has never arisen before.

  • Which are the best techniques to protect a 'homemade' framework from unlogged visitors?

    - by Hermet
    First of all, I would like to say that I have used the search box looking for a similar question unsuccessfully, maybe because of my poor english skills. The way I currently do this is checking in every single page that a session has been opened. If not, the user gets redirected to a 404 page, to seem like the file which has been requested doesn't exist. I really don't know if this is sure or there's a better and more safety way and I'm currently working with kind of confidential data that should never become public. Could you give me some tips? Or leave a link where I could find some? Thank you very much, and again excuse me for kicking the dictionary.

  • Giving proper credit to a projects contributors

    - by Greg B
    I've recently been working with an opensource library for a commercial product. The opensource code is distributed from the website of the company who sells the proprietary product as a zip file. The library is a (direct) port to C# of the original library which is in Java. As such, it uses methods instead of getter/setter properties. The code contains copyright notices to the supplier of the product. The C# port was originally provided to the company by a 3rd party individual. I have modified the source to be more C# like and added a couple of small features. I want to put my version of the code out there (Google code or where ever) so that C# users of the software can benefit from a more native feeling library. How can I and/or how should I amend the copyright notice to give proper credit to The comercial owner of the original source The guy who provided the original C# port Myself and anyone else who contributes to the project in the future The source is provided under the LGPL V2.1,

  • ASP.NET: How to assign ID to a field in DetailsView?

    - by jawonlee
    I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time. I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do? Thank you in advance.

  • SQL Server Reporting Services Bar Chart

    - by Avitus
    I am trying to create horizontal bar chart to look like a pill chart. I would like to take a either a stacked bar chart or a 100% stacked bar chart and put rounded ends onto this chart. I would only be using 1 row within the chart. One idea I had was just putting rounded images on either end of the chart to accomplish this but I'm not sure that this will give the smooth feel of a single pill. Does anyone have a good suggestion? I am not tied to the idea of using a chart object. But I would prefer to stay away from third party components that need to be purchased.

  • How do you use multiple versions of the same R package?

    - by Richie Cotton
    In order to be able to compare two versions of a package, I need to able to choose which version of the package that I load. R's package system is set to by default to overwrite existing packages, so that you always have the latest version. How do I override this behaviour? My thoughts so far are: I could get the package sources, edit the descriptions to give different names and build, in effect, two different packages. I'd rather be able to work directly with the binaries though, as it is much less hassle. I don't necessarily need to have both versions of the packages loaded at the same time (just installed somewhere at the same time). I could perhaps mess about with Sys.getenv('R_HOME') to change the place where R installs the packages, and then .libpaths() to change the place where R looks for them. This seems hacky though, so does anyone have any better ideas?

  • Is Kohana worth giving up on due to lack of Documentation & Examples?

    - by Asaf
    Hello, I've recently chose Kohana for a new project I'm doing And quite frankly, it's going a bit slow due to lack of resources. I've stumbled again and again on problems that I can't find a solution to Examples are probably the hardest to come by, so I'm considering Switching, especially because I'm only starting and I am still able to do it without to much trouble. I've been looking at CodeIgniter, although I know that Kohana is a branch out, CodeIgniter has far more examples and documentation, I'm wondering about your opinion. Edit: I would love to see some complete Kohana sites example, so that I would have a really quick reference. Nothing like already-working code to give you inspiration.

  • converting compressed Rich text (C#)

    - by Code Smack
    Hello, I have a string with CompressedRichText in it. I want to uncompressed it to standard RTF and then to plain Text. I am using VS 2008 C# Windows Application. I found references to C++ code to do it, but nothing directly in C#. here is a sample of what I am thinking... not much code though... private string _CompressedRichText = "5A46751234E1234A3214C12D34213412346F4"; private void button1_Click(object sender, EventArgs e) { //Convert to Uncompressed RTF richTextBox1.Text = //Some action //Convert to text textBox1.Text = //some action } This will at least give you an example of what I am thinking.

  • Determining if and where a photon will collide with a polygon in 3D space.

    - by Peter
    The problem is straight forward: 1) We have a photon traveling from Point 1 (x,y,z) to Point 2 (x,y,z), both of which could be located anywhere in 3D space. 2) We have a polygon that is both rotated randomly on the x-axis and/or y-axis and also located anywhere in 3D space. 3) We want to find: a) if the photon will collide with the polygon at all and b) if it does where will that be (x,y,z)? An image of the problem: http://dl.dropbox.com/u/3150177/Programming/3D/Math/Photon%20Path/Photon%20Path.png The aim of this is to calculate how the photon's path should be altered from an interaction(s) with the polygon(s). I am reading up on this subject now but I was wondering if anyone could give me a head start. Thanks in advance.

  • Console-App to get all open files for processes

    - by t.kehl
    Hi I am searching for a console-app (where I can pipe the output to a txt-file) which gives me a list of all current processes and the files which each process has open. The tool should also work when the user doesn't has administrativ-privilegues and it should also give file-path which are located on the network (UNC and absolute/mappings). Is there something like this which I can call from another tool and get the information? I am on a windows system. I have a open filename and need now to get the whole path for the file

  • Checking JRE version inside browser

    - by Brian Lewis
    Basically, I'm wanting to figure out the best way to check the user's JRE version on a web page. I have a link to a JNLP file that I only want to display if the user's JRE version is 1.6 or greater. I've been playing around with the deployJava JavaScript code (http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html) and have gotten it to work in every browser but Safari (by using deployJava.versionCheck). For whatever reason, Safari doesn't give the most updated JRE version number - I found this out by displaying the value of the getJREs() function. I have 1.6.0_20 installed, which is displayed in every other browser, but Safari keeps saying that only 1.5.0 is currently installed. I've also tried using the createWebStartLaunchButtonEx() function and specifying '1.6.0' as the minimum version, but when I click the button nothing happens (in any browser). Any suggestions?

  • php quick form creation

    - by Akshey
    Hi, I have been using php from some time and I have noticed that it takes a long time to create a form with validation using php. Are there any scripts or IDE wizards which can assist a programmer to create php forms quickly and also give the programmer flexibility to customize the form easily? I found some webservices which provide such services but they are mostly oriented towards non-programmers and the forms they generate are not easily customizable and do not support all kinds of functionalities. Infact, most of them are meant for generating contact forms. Regards, Akshey
