  • php mail function cannot send to [email protected] ??i

    - by user333216
    I'm having trouble when sending emails thorough the mail() function. I have a script that works perfectly fine for an email address like [email protected] but when the first part of the email is something with a dot like [email protected] it doesn't work and returns this error : Warning: mail() [function.mail ]: SMTP server response: 554 : Recipient address rejected: Relay access denied in confirmed.php on line 119 I am using real email address but have changed it in the above example. Any thoughts - I'm not a php master but surely there is an easy way to send emails to address with a 2 part first section?? Thanks in advance Ali

  • Working effectively unit tests / Anyone tried the in-assembly approach?

    - by CodingCrapper
    I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

  • Adding a search box to a windows forms web browser control that highlights text

    - by evan
    I have a windows forms (using c#) application. It displays a webpage and has a textbox/botton combination which can be used to search for text displayed to the user. Currently I search the inner text of all elements for the text in the textbox. And then I weed out the elements that are redundant (for example a word could be in a 'p' and 'b' element where the 'b' is a child element of 'p' so the element returned should be 'b'). Finally I run the ScrollIntoView(true) method on the found element. I'd now like to add a function that highlights the text (like if you search for a term in a real webbrowser). My first thought was to just inject html and or javascript code around the text but that seems like a messy solution. Any ideas on how I should do this? Thanks for your help!

  • Developing browser plug-ins?

    - by JavaMan
    I have a project that I'd like to try that involves developing an internet browser plug-in. I have knowledge in Java and DHTML, but nothing in the world of browser plug-in development. I thought I would just ask here then what is the most efficient way to develop a browser plug-in? If possible, I'd like to streamline the process so that getting the plug-in to work in different browsers involves as little work as possible. Can this be done? I'm not asking for a tutorial like the trolls do, just a few pointers that's all. I don't waste mine or anyone else's time.

  • Time order of messages

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

  • More elegant way to make a C++ member function change different member variables based on template p

    - by Eric Moyer
    Today, I wrote some code that needed to add elements to different container variables depending on the type of a template parameter. I solved it by writing a friend helper class specialized on its own template parameter which had a member variable of the original class. It saved me a few hundred lines of repeating myself without adding much complexity. However, it seemed kludgey. I would like to know if there is a better, more elegant way. The code below is a greatly simplified example illustrating the problem and my solution. It compiles in g++. #include <vector> #include <algorithm> #include <iostream> namespace myNS{ template<class Elt> struct Container{ std::vector<Elt> contents; template<class Iter> void set(Iter begin, Iter end){ contents.erase(contents.begin(), contents.end()); std::copy(begin, end, back_inserter(contents)); } }; struct User; namespace WkNS{ template<class Elt> struct Worker{ User& u; Worker(User& u):u(u){} template<class Iter> void set(Iter begin, Iter end); }; }; struct F{ int x; explicit F(int x):x(x){} }; struct G{ double x; explicit G(double x):x(x){} }; struct User{ Container<F> a; Container<G> b; template<class Elt> void doIt(Elt x, Elt y){ std::vector<Elt> v; v.push_back(x); v.push_back(y); Worker<Elt>(*this).set(v.begin(), v.end()); } }; namespace WkNS{ template<class Elt> template<class Iter> void Worker<Elt>::set(Iter begin, Iter end){ std::cout << "Set a." << std::endl; u.a.set(begin, end); } template<> template<class Iter> void Worker<G>::set(Iter begin, Iter end){ std::cout << "Set b." << std::endl; u.b.set(begin, end); } }; }; int main(){ using myNS::F; using myNS::G; myNS::User u; u.doIt(F(1),F(2)); u.doIt(G(3),G(4)); } User is the class I was writing. Worker is my helper class. I have it in its own namespace because I don't want it causing trouble outside myNS. Container is a container class whose definition I don't want to modify, but is used by User in its instance variables. doIt<F> should modify a. doIt<G> should modify b. F and G are open to limited modification if that would produce a more elegant solution. (As an example of one such modification, in the real application F's constructor takes a dummy parameter to make it look like G's constructor and save me from repeating myself.) In the real code, Worker is a friend of User and member variables are private. To make the example simpler to write, I made everything public. However, a solution that requires things to be public really doesn't answer my question. Given all these caveats, is there a better way to write User::doIt?

  • Java library to partially export a database while respecting referential integrity constraints

    - by Mwanji Ezana
    My production database is several GB's uncompressed and it's getting to be a pain to download and run locally when trying to reproduce a bug or test a feature with real data. I would like to be able to select the specific records that interest me, then have the library figure out what other records are necessary to produce a dataset that respects the databases integrity constraints and finally print it out as a list of insert statements or dump that I can restore. For example: given Author, Blog and Comment tables when I select comments posted after a certain date I should get inserts for the Blog records the comments have foreign keys to and the Author records those Blogs have foreign keys to.

  • Cursors vs Procedures in SQL

    - by CogitoErgoSum
    So, I just learned about CURSORS but still don't exactly grasp them. What is the difference between a cursor and procedure or even a function? So far from the various examples (DECLARE CURSOR ... SELECT ... FROM ...) It seems at most its a variable to hold a query. Is the data real time, or a snapshot of when the cursor was declared? i.e. I have a table with one row and one col with a value of 2. I do DECLARE CURSOR ... SELECT * FROM table1 I then insert a new row with a value of 3. When I run the cursor, would I Just get the one row from before the cursor was declared, or both rows? Thanks

  • Spring Roo and aspect-oriented programming

    - by marcos
    Hello, i've been running some experiments of my own with Spring Roo and it seems to be pretty cool, but i noticed that this tool makes heavy use of AOP on the model layer. I'm thinking about creating a real project using Roo and what i would like to know is: Why AOP is everywhere? Is That ok? What are advantages and disadvantages of this approach? I'm quite new to aspect-oriented programming and some guidance would be greatly appreciated. Thanks in advance!

  • mod_perl memory leak

    - by marghi
    Hello, I recently discovered that one of our sites has a memory leak in it, it's very strange because it happened all of the sudden. I've used GTop to measure the memory size per process and it tells me that the real value is somewhere around 65 MB (on the server) per request and and additional 5 MB shared. I tried preloading the modules in the startup.pl file a indicated in the performance tuning article for mod_perl. Nothing happened if fact the shared memory decreased down to 3.7 MB, in this situation I thought that my application is leaking memory do before any line of code got executed I measured the memory just to find out that the total value is in fact 64 MB, my questions are: Is there a default preallocation of memory for each process? Is there a configuration issue? Is mod_perl leaking memory ? Thank you very much.

  • Relvance of 'public' contructor in abstract class.

    - by Amby
    Is there any relevance of a 'public' constructor in an abstract class? I can not think of any possible way to use it, in that case shouldn't it be treated as error by compiler (C#, not sure if other languages allow that). Sample Code: internal abstract class Vehicle { public Vehicle() { } } The C# compiler allows this code to compile, while there is no way i can call this contructor from the outside world. It can be called from derived classes only. So shouldn't it allow 'protected' and 'private' modifiers only. Please comment.

  • unsupported major .minor version 51.0

    - by ERJAN
    I am trying to use notepad++ as my all-in-one tool edit, run, compile etc. I have jre installed, i have setup my path variable to .../bin directory. When I run my "Hello world" in notepad++ , I get this message: java.lang.UnsupportedClassVersionError: test_hello_world : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(Unknown Source) ......................................... I think the problem here is about versions, some version of java may be old or too new. how do i fix it? should i install jdk , and setup my path variable to JDK instead of jre? difference between PATH variable in jre or jdk?

  • Netbeans C++ not finding standard libraries (Macintosh)

    - by Grue
    Hello everyone! I am trying to use Netbeans 6.7 (on a Mac) to create C++ applications. I started out with the standard "Hello World," just to test if everything was working correctly. First try std and could not be found. So I tried reinstalling the developer tools on my Mac OS X disk. After that Netbeans updated its c++ compiler info, but still cannot find std or . Odder than this XCode seems to be working with C++ perfectly fine. Any help fixing this would be greatly appreciated.

  • How hard is it for a .NET programmer to learn Objective C and Cocoa?

    - by rsteckly
    Hi, I'm trying to build a dual platform application for a company of my own I'm trying to start at night. I have the .NET version done, but have not finished the UI part. I'm thinking of buying some 3rd party controls. If I buy these controls, however, they clearly will only work in my Windows version. I'm wondering if I should try to do the UI in GTK# and use Mono with CocoaSharp or just build the thing in MS technology and teach myself the Mac side? I'm just really unfamiliar with the Mac world and am wondering how much of a learning curve there might be. I've thought perhaps of rewriting my core logic in Ruby or Python. This why I could use the .NET version with .NET controls and presumably hook the same code up on the Mac. It's an educational app targeted at consumers. As such, it shouldn't require a lot of technical sophistication to install.

  • Clojure load files

    - by Nate
    I'm trying to set up a simple clojure project, and I'm not sure how to load files between the project. I'm sure that the answer is in the documentation, but I can't find a simple answer any where and I'm not sure where to look. Essentially, my directory looks like this: Clojure/ clojure/ clojure.jar other clojure files clojure-contrib/ clojure-contrib.jar other contrib files project/ main.clj utils.clj And I want main.clj to be something like this: (ns project.main (:require project.utils)) (greet) and utils.clj to be something like this: (ns project.utils) (defn greet [] (println "Hello, World!")) But that fails with: Exception in thread "main" java.io.FileNotFoundException: Could not locate project/utils__init.class or project/utils.clj on classpath: (main.clj:1) When I attempt to run it. How do you set up a simple clojure project?

  • What does it mean to do/determine something "programmatically"?

    - by Chris Lutz
    Programmatically. (alt. programmically) I've never used it, but I see it in questions a lot, i.e. "How to programmatically determine [insert task here]". Firefox immediately tells me that neither of these two words are real (at least, it doesn't recognize them). I've also never seen them used anywhere but here. 1) What does it mean to do/determine something "programmatically"? 2) Why do so many people ask how to do/determine something "programmatically"? Isn't it assumed that, if you're asking how to do something on a programming help board, you're asking how to do it "programmatically"? 3) Why is it that I've never seen the word "programmatically" anywhere else?

  • What's the best way to run a process remotely with capturing the output ?

    - by Homam
    Hi all, I have a windows service responsible for running processes on a remote machine with capturing the output, I googled for that and read a lot of articles and threads, I found two ways: 1) using WMI for call the remote process like this example: http://www.codeproject.com/KB/cs/EverythingInWmi02.aspx 2) using the PsExec tool by System.Diagnostic.Process class ever way of these has many problems, the WMI doesn't support returning the output and doesn't support "WaitingToExit" It just call the process and return the PId, and the PsExec couldn't capture the output programmatically by System.Diagnostic.Process in a clear way, I found only workarounds like redirect the output to a file then read the redirected file..etc, I need a real solution please

  • How to get or make a WPF WebBrowser with a visual.

    - by Trainee4Life
    Having problems related to WPF WebBrowser not having a visual. Reason being, that it actually a wrapper around the winforms browser. Anyways, I searched the web for any solution to this problem, and got hold of the following suggestions: http://chriscavanagh.wordpress.com/2009/08/25/a-real-wpf-webbrowser/ http://rob.runtothehills.org/archives/60 The first one solves everything, but seems like an overkill. Plus, the dll's should be licensed for commercial use. The second one seems simple, but not able to figure out when to refresh the screen. Plus there's so much to do like sending mouse and keyboard messages to the webbrowser. P.S. The problem I'm trying to solve is to show the same webbrowser on different windows. They both must be interactive, and always in sync visually.

  • get data from asp page

    - by sam
    I am wondering if there is anyway to grab the html that is generated from an ASP page. I am trying to pull a table from the page, and I foolishly used a static html page so I would not have to be constantly querying the server where this page resides while I tested out my code. The javascript code I wrote to grab to unlabeled table from the page works. Then when I put it into practice with the real page and found that the ASP page does not generate a viewable page with a jquery .get request on the URL. Is there any way to query the page for the table I need so that the ASP page returns a valid page on request? (I am also limited to using javascript and perl for this, the server where this will reside will not run php and I have no desire to learn ASP.NET to solve this by adding to the issue of proprietary software)

  • Remove items from SWT tables

    - by Dima
    This is more of an answer I'd like to share for the problem I was chasing for some time in RCP application using large SWT tables. The problem is the performance of SWT Table.remove(int start, int end) method. It gives really bad performance - about 50msec per 100 items on my Windows XP. But the real show stopper was on Vista and Windows 7, where deleting 100 items would take up to 5 seconds! Looking into the source code of the Table shows that there are huge amount of windowing events flying around in this call.. That brings the windowing system to its knees. The solution was to hide the damn thing during this call: table.setVisible(false); table.remove(from, to); table.setVisible(true); That does wonders - deleting 500 items on both XP & Windows7 takes ~15msec, which is just an overhead for printing out time stamps I used. nice :)

  • How to get started with embedded systems in the aircraft or submarine industries?

    - by Jason
    Hi, Not 100% sure how to frame this question but here goes... I currently work as a Rails developer but want to work on more substancial / "meaty" projects and have always been very interested in embedded systems, especially systems that run on aircraft and especially submarines.....I know strange combination. I have been doing some searching & found lockheed martin produces a lot of underwater systems for various navys around the world e.g. http://www.naval-technology.com/projects/nssn/ However, there is very little information about what software is used within these systems, what OS's they use or anything else "technical", presume there is a lot of C / C++ involved but that is just a guess... so its hard to know where to even begin learning what is required to potential work in these areas. Just wondering if anyone has any experiance working with or more information about embeddeed systems in either the airline (onboard flight systems) or especially submarine systems? Thanks!

  • jQuery plugin: Validation can't be customized without setting all fields to 'required'?

    - by rasx
    I've spent the day looking at jQuery plugin: Validation by Jörn Zaefferer. I notice that it works fine as long as you call the validate() method without options. In my little squalid world, as soon as I add options, like errorPlacement, I notice that validation ignores form fields that are not marked required. I also notice that many, many demos mark all fields required---or do not pass options. Am I writing about anything familiar here? Or should I astral project to a parallel universe?

  • AS3: Synchronize Timer event to actual time?

    - by Nebs
    I plan to use a timer event to fire every second (for a clock application). I may be wrong, but I assume that there will probably be a (very slight) sync issue with the actual system time. For example the timer event might fire when the actual system time milliseconds are at 500 instead of 0 (meaning the seconds will be partially 'out of phase' if you will). Is there a way to either synchronize the timer event to the real time or get some kind of system time event to fire when an second ticks in AS3? Also if I set a Timer to fire every 1000 milliseconds, is that guaranteed or can there be some offset based on the application load? These are probably negligible issues but I'm just curious. Thanks.
