• What is the "stringWithContentsOfURL" replacement for objective C?

  - by Graeme

  I found a tutorial on the net that uses the stringWithContentsOfURL command that is now deprecated as of iPhone OS 3.0. However I can't find out what I'm meant to use instead, and how to implement it. Below is the code surrounding the stringWithContentsOfURL line in case you need it for reference. NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", [addressField.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]]; NSArray *listItems = [locationString componentsSeparatedByString:@","]; Thanks.

• Silverlight MVVM conversion from WPF

  - by IrishJoker

  I was reading this article - http://msdn.microsoft.com/en-us/magazine/dd419663.aspx And I came across this piece of code in the WPF Demo application that came with the article. This template applies a CustomerView to an instance of the CustomerViewModel class shown in the main window. <DataTemplate DataType="{x:Type vm:CustomerViewModel}"> <vw:CustomerView /> </DataTemplate> I substituted the angle brackets for square brackets - not sure how to post them. The code is in the MainWindowResourses.xaml and the code starts on line 19. Anyone know how I can do this in Silverlight ?? We don't have the DataType and I need to be able to tell the app that this View is associated with this ViewModel - so I can create a tab control with different view like the demo app. Cheers, EC

• How can I convert .eps files to .jpg in ASP.NET?

  - by Mike C

  I am trying to convert uploaded .eps files to .jpg in my ASP.net application and I am having a hard time finding a .net library that will let me do this. I have tried using the ImageMagick libraries, but I don't have root access to the server in order to install the standard binaries, or run the command line executables. I have also tried the slightly modified project from CodeProject, but it was designed in VS2005 and I have VS2008 and 2010 and I think I run into some compatibility issues while trying to compile and execute the project. Is there a simpler solution available that just works natively in .NET? Thanks, Mike

• How do I sign exes and dlls with my code signing certificate

  - by Tim

  (I purchased a code signing cert from Thawte and have been going out of my mind with frustration at the whole process. What I have from them are: .spc / .p7b file .pvk file (NOTE I do not have a pfx file from them. God knows why, but I have been fighting with their tech support for a week) In any case I find "help" links on their site and at MS for signcode.exe which is useless for me because I can't find that exe on my machine, however I do have signtool.exe. Unfortunately i am mystified at the command line parameters listed on this MS help site. Specifically, what parameters do I use and what values? I tried what I thought was obvious but it does not work at all. I can get the signing wizard to work, however I need this to work non-interactively in a hudson CI batch file. It really doesn't seem like it should be this difficult, but so far it is all black magic. thanks for any help

• How to set target hosts in Fabric file

  - by ssc

  I want to use Fabric to deploy my web app code to development, staging and production servers. My fabfile: def deploy_2_dev(): deploy('dev') def deploy_2_staging(): deploy('staging') def deploy_2_prod(): deploy('prod') def deploy(server): print 'env.hosts:', env.hosts env.hosts = [server] print 'env.hosts:', env.hosts Sample output: host:folder user$ fab deploy_2_dev env.hosts: [] env.hosts: ['dev'] No hosts found. Please specify (single) host string for connection: When I create a set_hosts() task as shown in the Fabric docs, env.hosts is set properly. However, this is not a viable option, neither is a decorator. Passing hosts on the command line would ultimately result in some kind of shell script that calls the fabfile, I would prefer having one single tool do the job properly. It says in the Fabric docs that 'env.hosts is simply a Python list object'. From my observations, this is simply not true. Can anyone explain what is going on here ? How can I set the host to deploy to ?

  - by Anand

  I am programming in Java I have the code as: byte[] b = test.getBytes(); In the api it is specified that if we do not specify character encoding it takes the default platform character encoding.

• Ethics and Law of modified LGPL code deployment in a commercial software

  - by dr. evil

  First bit of the question: What are the legal requirements of LGPL code during the deployment of a commercial product? Software package should include LGPL licence file Anything else? Shall we add a line to our "software agreement text" where you need to click next in the installer ? Second bit, Is there any known / accepted ways of distributing the changed library. Since it's LGPL anything derived from it should be licenced under LGPL. But what about after that? Shall we just send a copy to the original author? Shall we put it in our website so people can download? Or ship the source code with the product? Or just put a note that saying "e-mail us for the source code of this library".

• Easier debugging stl array

  - by bobobobo

  In MSVC++ I have a vector. Whenever you go out of bounds of the vector (in debug mode, launched as "Start Debugging"), when you step out of bounds of the vector the program halts with a dialog box: Microsoft Visual C++ Debug Library ==== Debug Assertion Failed! Expression: Vector subscript out of range Abort | Retry | Ignore So what I want though is the MSVC++ debugger within visual studio to STOP AT THE LINE WHERE THE OUT OF BOUNDS OCCURRED, not give me this dialog box. How can I cause the program to "break" properly and be able to step through code /inspect variables when an out of bounds occurs on an STL vector?

• Mac OS X, MySQL Preference Pane doesn't work

  - by Steve Kuo

  I downloaded and installed MySQL 5.1.47 for OS X 10.6 using the DMG archive: mysql-5.1.47-osx10.6-x86_64.dmg I also installed MySQL.prefPane and MySQLStartupItem.pkg. MySQL.prefPane is a Preference Pane. The problem is, whenever I attempt to start/stop MySQL from the Preference Pane, System Preferences just hangs. It runs at about 50% CPU forever, eventually I have for force quit System Preferences. The same thing happens if I toggle "Automatically Start MySQL Server on Startup". Basically the MySQL Preference Pane is not functional. Note that I have no problem starting MySQL from the command line: sudo /usr/local/mysql/bin/mysqld_safe I have tried reinstalling MySQL and the Preference Pane. I'm using the standard installation location, nothing out of the ordinary. Every time the MySQL Preference Pane just hangs. I'm doing this on a Macbook Pro (Intel) running OS X 10.6.3. There are no old versions of MySQL on this machine.

• Eclipse Pydev: Supress no-self errors in python wrappers generated with swig

  - by Christian

  Hi, when generating python wrappers with swig the python wrapper classes in the generated python file do not have an explicit self parameter, for example see below: class PySwigIterator(_object): def value(*args): return _spatiotemporalnmf.PySwigIterator_value(*args) def incr(*args): return _spatiotemporalnmf.PySwigIterator_incr(*args) def decr(*args): return _spatiotemporalnmf.PySwigIterator_decr(*args) def distance(*args): return _spatiotemporalnmf.PySwigIterator_distance(*args) I am developing with the eclipse pluging Pydev. Pydev always shows an error when it detects a method without explicit self parameter. I am aware of two methods to get rid of the errors: First, disable error checking for the whole project in the Pydev preferences. Second, add a #@NoSelf to every line with an error. I don't want to use the first one, because I still want to get error warnings for my non-swig-generated files. Obviously the second one is also not very good, because I would have to do it by hand and every time I generate the file again, all #@NoSelfs will be gone. My Question now is, is there a better way to achieve this? Thanks

• Tool to aid Code Review

  - by Prakash

  For our small team of 20 developers, we used do code review like: Make a label in svn and publish the label to the reviewers Reviewers checkout the code and add comments in line (with marker like: // REVIEWER_NAME::REVIEW COMMENT:) After all comments are in, reviewer checks in the code, preferably with new label. Developer checks the comments and makes changes (if appropriate) Developer keeps an excel sheet report for considered changes and reasons for ignored comments Problem: Developer needs to keep track of multiple labels which might have same comments Sometimes we even do One on One review and if we really have time, even do Table review (team of reviewers looks at the code on projector, on the fly, and pass comment) I was wondering: Are you guys using any specific tool which helps to do code reviews smoother? I have heard of Code Collaborator. But have anyone used that? Is it worth the money?

• Convert Microsoft Visio Drawing (vsd) to PDF automatically

  - by nhinkle

  An open-source project I am working on uses Visio drawings for documentation, which are checked into source control. For those working on the project who don't own Visio, we have been converting the vsd files to PDFs so that they can still view them. It's not too difficult to save a copy as a PDF when making changes to the documentation, but we would like an automated way to do this conversion, so that we can set it up as a pre-checkin script in the SVN client. If anybody knows of a way to do this, either using something built-in to Visio, or with an outside script or command line tool, we would appreciate it. Edit: Thanks to the suggestion below, I have found the Visio Viewer 2010. This will be helpful for our contributors using Windows. We would still like to have the ability to create PDFs though, as there are readers available on every major operating system, and our contributors will not be using only Windows.

• Python (Twisted) - reading from fifo and sending read data to multiple protocols

  - by SpankMe

  Hi, Im trying to write some kind of multi protocol bot (jabber/irc) that would read messages from fifo file (one liners mostly) and then send them to irc channel and jabber contacts. So far, I managed to create two factories to connect to jabber and irc, and they seem to be working. However, I've problem with reading the fifo file - I have no idea how to read it in a loop (open file, read line, close file, jump to open file and so on) outside of reactor loop to get the data I need to send, and then get that data to reactor loop for sending in both protocols. I've been looking for information on how to do it in best way, but Im totally lost in the dark. Any suggestion/help would be highly appreciated. Thanks in advance!

• Vertical-centering and overflow Excel-style in CSS?

  - by Eric Grange

  Is there a way to perform a vertical centering of a variable-sized multi-line content within a fixed-size div, with hidden overflow? The aim would be to reproduce what you can see in Excel cells: when the content fits the container, it should be vertically centered, when it is larger, the parts that overflow should be hidden (and the content still vertically aligned), like in an Excel cell whose neighbours aren't empty. I know how to vertically center using CSS, I know how to hide overflow when the content isn't vertically centered, but I've no idea how to do both at the same time... Is Javascript the only answer? The trick is that CSS positioning approaches don't work with variable-sized content (my content is dynamic text), and when you use display:table-cell, it effectively disables CSS overflow control (and the container grows to accomodate the content).

• django __search - trying to do x+y__search

  - by ckohrman

  I'm trying to do something like this with django: Q(x+y__search = z) I'm using __search to boolean search for a list of words within two separate lists (requiredTags, preferredTags). Line 10 is the one I have questions about. I want to see if the list of words (requTags) is found among requiredTags or preferredTags. requTags="" prefeTags="" for i in reqTags: if(i!=""): requTags+="+"+i+" " for i in prefTags: if(i!=""): prefeTags+=i+" " if(requTags!=""): query=query &( Q(requiredTags__search + preferredTags__search = requTags)) if(prefeTags!=""): query=query &( Q(requiredTags__search = prefeTags) | Q(preferredTags__search = prefeTags)) For instance: requTags might be: +beans +rice +cheese. requiredTags might be: beans,rice,tortilla preferredTags might be: cheese I didn't see any way to combine requiredTags and preferredTags in the documentation. Any help would be appreciated as I'm a beginner...

• Enthought Canopy - passing sys.argv from PySide Qt program

  - by user2541559

  I've recently been looking at the Enthought distro of iPython. Today I decided to see if I could get some Qt GUI progs running and was successful after making minor changes. Simple example: import sys from PySide import QtGui # was 'from PyQT4 import QtGui' # app = QtGui.QApplication(sys.argv) -- not needed win = QtGui.QWidget() win.resize(320, 240) win.setWindowTitle("Hello MIT 6X!") win.show() sys.exit() # was 'sys.exit(app.exec_())' But I would like to be able to pass sys.argv in some cases. Most example code I see is in the form of the commented out 'app = ' line above. If I include it, I get 'RuntimeError: A QApplication instance already exists.' Suggestions for passing arguments appreciated. Nick

• cannot convert from 'cli::array<Type> ^' to 'cli::array<Type> ^[]'

  I'm pretty new to C++/CLI and I am trying to convert a System::String to a System::Char array. Here's what I have so far: private: System::Void modeToolStripMenuItem_Click(System::Object^ sender, System::EventArgs^ e) { Mode frmMode; if(frmMode.ShowDialog() == System::Windows::Forms::DialogResult::OK){ array <Char>^ load [] = gcnew array<Char>(txtbxName->Text->ToCharArray()); } } txtbxName is a textbox inside a the form. Supposedly, this should work, but I get the compiler error: error C2440: cannot convert from 'cli::array<Type> ^' to 'cli::array<Type> ^[]' for the fourth line of the snippet.

• How to override ant task stored in ant lib directory

  - by mchr

  At my work we use AspectJ in some of our Java projects. To get this to work with ant builds we have been placing aspectjtools.jar within ant/lib/. I am now working on a particular Java project and need to use a newer version of aspectJ. I don't want to have to get everyone who uses the project to update their local copy of aspectjtools.jar. Instead, I tried adding the newer aspectjtools.jar to the lib directory of the project and adding the following line to build.xml. <taskdef resource="org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties" classpath="./lib/aspectjtools.jar" /> However, this doesn't work as I hoped as the ANT classloader loads jars from ant/lib/ in preference to the jar I specify in the taskdef classpath. Is there any way to force ant to pick the jar checked into my project instead?

• Problem loading XMLDocument with non standard tags

  - by David Conde

  Hi, I have a code needed to load an XML document from a reader, something like this: private static XmlDocument GetDocumentStream(string xmlAddress) { var settings = new XmlReaderSettings(); settings.DtdProcessing = DtdProcessing.Ignore; settings.ValidationFlags = XmlSchemaValidationFlags.None; var reader = XmlReader.Create(xmlAddress, settings); document.Load(reader); return document; } But in my XML document, I have nodes like this one: <link rel="edit-media" title="Package" href="Packages(Id='51Degrees.mobi',Version='0.1.11.9')/$value" /> Is to my understanding that the node should be like <link rel="edit-media" title="Package"></link> But, I don't create the Xml document and I certainly don't want to change it, but when I try to load the XML document, the document.Load line throws an exception. To be more specific, the XML file is the RSS source for the nuPack project. Any ideas would be very appreaciated on how to be able to read this document properly.
