  • Activating Eclipse Django Editor on OS X

    - by hekevintran
    I installed a plugin for Eclipse called Django Editor. I can't figure out how to use it. The editor is not in my list of editors so I cannot do "Open with Django Editor" on a file nor associate a file extension with it. It appears nowhere in my preferences. How can I activate this editor? I am running Mac OS X 10.5.8 and Eclipse 3.5.2 Galileo.

    - by muku
    Hello guys, What I want to do is simple. I have a generic list of objects. Let's say the object class contains a property named Height. What I want to do is bind a textbox's text in the UI with this list and when i change the value in the textbox then all objects in the list update their height value. I am new in WPF, I have studied the MVVM pattern, I can do simple data binding but i can't figure out how to do this :'( Thanks!

  • How can I troubleshoot an APPCRASH in Internet Explorer?

    - by Schnapple
    I'm writing an ActiveX control using the firebreath framework (hi taxilian!) and while it technically works, I'm running into a weird issue that appears to be unique to me. I've followed the instructions to create a simple plugin and then I ran it in Internet Explorer 8 on Windows 7 x64 (firebreath sets up a test page for the control). But as soon as I try to test it (clicking on a link that fires off JavaScript to interact with the control), IE crashes. Hard. "Internet Explorer has stopped working" style. If I try the control in Firefox (the resulting registered DLL can also be called as a Firefox plugin using a MIME type), it works fine. If I try it on my XP box, it works fine. I emailed the DLL and the testing page to a coworker in the next cube who is like me also running Windows 7 x64 and it works for him just fine as well, so it's not something unique to Windows 7 or x64. When it crashes I get this message: Problem signature: Problem Event Name: APPCRASH Application Name: iexplore.exe Application Version: 8.0.7600.16385 Application Timestamp: 4a5bc69e Fault Module Name: RPCRT4.dll Fault Module Version: 6.1.7600.16385 Fault Module Timestamp: 4a5bdb3b Exception Code: c0000005 Exception Offset: 000220b1 OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 Which tells me nothing extremely useful. I can have it attach to a debugger but it just tells me a long list of DLL's, none of which are the ActiveX control in question. It's almost like it's not even getting there. I did a sfc /scannow yesterday to see if anything on my system is corrupt and nothing came up as wrong. I tried various different security levels in IE, but nothing seems to have any effect. As this is a development machine there has been all matter of crap installed on it, so I figure it's bound to be something I've installed since October (when Win7 was released) but I cannot figure out what it is. I presume the information it's giving me when I attach to Visual Studio is useful somehow but I don't know how to interpret it. Admittedly I'm mainly a C#/.NET developer who's a bit out of his element with C/C++ and troubleshooting native code, but does anyone have any advice on how to proceed on figuring out why this very simple ActiveX control crashes IE on my machine and nowhere else?

  • jQuery form duplicate email validation on exit

    - by Zach Girod
    I have a site and I am using this plugin for validation in the registration process. I have seen sites where when you exit the email address field, it goes out and checks to see if the email address exists before you hits the submit button. I know this is ajax but I cannot figure it out. How do you validate if an email address (or any field) already exists before the users submits the form?

  • MySQL table partitioning qn:

    - by JVXR
    I have a table (innodb) that will have billions of records eventually. Every 2nd week I expect ~ 500K records to get dropped into the table. I would want to partition this table based on the date on which the data is imported - luckily this is a field in the table that is of the format yyyy-mm-dd - Is it possible to partition it based on this date column ? I tried looking at the 18th chapter of mysql docs but couldn't figure out if this is possible. -tia

  • Benefits of implementing OAuth

    - by zfranciscus
    From a webservice provider point of view what is the benefit of asking users to create an account or login using 3rd party web service provider (e.g: Twitter or facebook) to log into your site with? Wouldn't it be easier to ask the user to provide their twitter or facebook login and use that to pull the user's twitter or facebook data? It is safer to use OAuth than giving some one the internet our twitter or facebook login credential. But, I can't figure out the benefit from the web service point of view.

  • Percentage calculation around 0.5 (0.4 = -20% and 0.6 = +20%)

    - by Micheal
    I'm in a strange situation where I have a value of 0.5 and I want to convert the values from 0.5 to 1 to be a percentage and from 0.5 to 0 to be a negative percentage. As it says in the title 0.4 should be -20%, 0.3 should be -40% and 0.1 should be -80%. I'm sure this is a simple problem, but my mind is just refusing to figure it out :) Can anyone help? :)

    - by Chris Farmer
    I am trying to get a build process set up in TeamCity 5, and I am encountering an access denied error when trying to copy some files.

The trouble is that I can't figure out how to change those settings on the build agent. How can I change the build user identity?

  • Can I use this technique to provide free email service for my users?

    - by Naughty.Coder
    I'll let users register their [email protected] ,,, they enter their members area where they can : 1- send emails ( easy to do) 2- receive emails .. for receiving emails , I'll use a catch all email account , read the email and figure to whom it's sent (username), and then I save it on the database with userid of the username who has registerd ! Do I miss something here ... is it really this simple (if I don't have an email server) ?

  • Python dealing with dates and times

    - by randombits
    I'm looking for a solution to the following: Given today's date, figure out what month was before. So 2 should return for today, since it is currently March, the third month of the year. 12 should return for January. Then based on that, I need to be able to iterate through a directory and find all files that were created that month. Bonus points would include finding the most current file created for the previous month.

  • need a regex to parse a csv file with double quotes in php

    - by Brandon G
    Trying to parse a csv file that has all the data wrapped in double quotes, because there may be commas in the double quotes. Looks like this: $songs = '"1, 2, 3, 4 (I Love You)","Plain White T's","CBE10-22",15,"CBE10-22","","","CB",984,"","10/05/10"'; $regResult = preg_match( "", $songs, $matches ); I can't figure out a regex that will return the data between the quotes as the matches. I'm sure there is some regex master that can help me with this.

  • Soon to be PhD in Computer Science - Which Path to Follow?

    - by mttr
    I am going to submit my PhD thesis within the next six months. My PhD is on managing the availabiity of large-scale distributed systems, so I have some experience actually building non-trivial systems (+ I have four years experience working as a programmer). I am now trying to figure out what I should do following the PhD. I enjoy research (a quick definition: identify problem, come up with solution, ask interesting questions, find ways to answer them, build system, experiment, contribute some new knowledge and publish). I also like teaching and supervising students. It would seem that a career in academia is the ideal thing to do (can work on non-trivial problems and contribute something of use to some or more people). However, a career in academia has two significant drawbacks. First, it can be difficult to gain access to real systems with real users which then display real problems. This creates the danger that you do work that seems important (to you and maybe to some of your colleagues), but is not really relevant to anything or anyone. Second, the pay is pretty sad. Apparently, you have to sacrifice this for the privilege of doing research. I enjoy programming, but don't just want to hack some web-based system for the rest of my life. That is, working in IT for a bank is not a future I see myself enjoying. I want to work on interesting problms (that's difficult to define clearly): things where you don't know how to start, that take some time to figure out and attack, that require a rigorous approach to demonstrate that the problem has been solved, and problems that need a solution in the real world. Give the experience of people on stackoverflow, what do you think suitable options are and why (or alternatively, what gaps in my thinking does the above reveal)? Is industrial research (aka IBM Research, Microsoft Research) the only alternative avenue to a career in academia? What other areas, companies, occupations, etc. could provide me with stimulating, inspiring work? Which regions, countries am I most likely to find such work? Please share your experience.

  • Catching an exception class within a template

    - by Todd Bauer
    I'm having a problem using the exception class Overflow() for a Stack template I'm creating. If I define the class regularly there is no problem. If I define the class as a template, I cannot make my call to catch() work properly. I have a feeling it's simply syntax, but I can't figure it out for the life of me. #include<iostream> #include<exception> using namespace std; template <class T> class Stack { private: T *stackArray; int size; int top; public: Stack(int size) { this->size = size; stackArray = new T[size]; top = 0; } ~Stack() { delete[] stackArray; } void push(T value) { if (isFull()) throw Overflow(); stackArray[top] = value; top++; } bool isFull() { if (top == size) return true; else return false; } class Overflow {}; }; int main() { try { Stack<double> Stack(5); Stack.push( 5.0); Stack.push(10.1); Stack.push(15.2); Stack.push(20.3); Stack.push(25.4); Stack.push(30.5); } catch (Stack::Overflow) { cout << "ERROR! The stack is full.\n"; } return 0; } The problem is in the catch (Stack::Overflow) statement. As I said, if the class is not a template, this works just fine. However, once I define it as a template, this ceases to work. I've tried all sorts of syntaxes, but I always get one of two sets of error messages from the compiler. If I use catch(Stack::Overflow): ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2316: 'Stack::Overflow' : cannot be caught as the destructor and/or copy constructor are inaccessible EDIT: I meant If I use catch(Stack<double>::Overflow) or any variety thereof: ch18pr01.cpp(89) : error C2061: syntax error : identifier 'Stack' ch18pr01.cpp(89) : error C2310: catch handlers must specify one type ch18pr01.cpp(95) : error C2317: 'try' block starting on line '75' has no catch handlers I simply can not figure this out. Does anyone have any idea?

  • JQuery overriding the themeroller style

    - by Paul Connolly
    Hi, In my accordian control I want to override the header style to show a red background instead of the default theme colour if ever the user control (e.g user's name and address input) in that particular pane returns a validation boolean of false. I'm ok with how to use .Toggle to change the class but can't figure out how to grab the themeroller class in the first place. How would I do this? Thanks Paul
