  • Xcode: how to know a header file is actually imported?

    - by Philip007
    To be specific, I am using RestKit framework. I want to use a framework class category called RKObjectManager+RKTableController in my view controller mainTVC. Here is my #import section in mainTVC.m: // framework headers, which should be enough #import <RestKit/RestKit.h> #import <RestKit/UI.h> // my project headers, not relating to framework #import "MainTVC.h" #import "Photo.h" // Do this to guarantee import does happen. But still got error, see below #import <RestKit/RKObjectManager+RKTableController.h> However, Xcode issue an error: No known class method for selector 'fetchRequest:groupedBy:inContext:' For reference, this method is a class method declared only in category header RKObjectManager+RKTableController.h, but not in 'RKObjectManager.h`. Also, I added -ObjC and -all_load to "other linker flags" in build settings, if that's relevant. I suspect the error is caused by the fact that category header is not actually imported somehow. How can I verify that? Or the error is caused by other reasons that I am not aware of. What am I doing wrong?

  • Fastest way to convert file from latin1 to utf-8 in python.

    - by xsaero00
    I need fastest way to convert files from latin1 to utf-8 in python. The files are large ~ 2G. ( I am moving DB data ). So far I have import codecs infile = codecs.open(tmpfile, 'r', encoding='latin1') outfile = codecs.open(tmpfile1, 'w', encoding='utf-8') for line in infile: outfile.write(line) infile.close() outfile.close() but it is still slow. The conversion takes one fourth of the whole migration time. I could also use a linux command line utility if it is faster than native python code.

  • Which file is the COM++ object and how do I import it to .NET?

    - by Bad Man
    I'm trying to write a COM++ object wrapper around a Qt widget (control) I wrote so I can use it in future .NET projects. e.g.: public __gc class comWidget; In the compile directory are the .exe, an exe.intermediate.manifest, and the comWidget.obj, and also some other crap files (.pdb, etc). So what/how do I import into .NET? I feel like I'm missing an important step for registering the object or whatever, but all these tutorials are terrible outdated and ridiculously unhelpful (for instance, I'm using the old CLR syntax because I can't find any good docs on the new stuff, thx again M$ for being lazy faggots as usual)

  • How does JSON compare to XML in terms of file size and serialisation/deserialisation time?

    - by nbolton
    I have an application that performs a little slow over the internet due to bandwidth reasons. I have enabled GZip which has improved download time by a significant amout, but I was also considering whether or not I could switch from XML to JSON in order to squeeze out that last bit of performance. Would using JSON make the message size significantly smaller, or just somewhat smaller? Let's say we're talking about 250kB of XML data (which compresses to 30kB).

  • How do I re-create a MySQL InnoDB table from an .ibd file?

    - by knorv
    Assume that the following MySQL files have been restored from a backup tape: tablename.frm tablename.ibd Furthermore, assume that the MySQL installation was running with innodb_file_per_table and that the database was cleanly shutdown with mysqladmin shutdown. Given a fresh install of the same MySQL version that the restored MySQL files were taken from, how do I import the data from tablename.ibd/tablename.frm into this new install?

  • Is it possible to query a XML file with SQL?

    - by Monty
    Currently I'm working on a case where we don't want to change to much on a c#/wpf program, but like to add a feature. Currently we allow certain users to add sql queries to a database to retrieve customer data, hereby a custom connection string/ provider name must be specified. With this information it's possible to create the connection and obtain the data with c#. However we like to add the possibility to allow that user group to query XML files too, with a certain connection string/ provider name. I just had a look for possibities in .net to do that, but can't seem to find a decent way... Is something like this possible? (OleDb/ODBC way maybe?) Thanks in advance.

  • Is it possible to virtualize war file execution without separate J2EE container deployments?

    - by Smith
    Let's say I want to allow my developers to upload their war files to a web app (not the application server itself) running on our intranet and that web app would then run those wars as if they were separate apps deployed individually in our J2EE container. In other words, we are not actually deploying the wars as separate apps in the container - they are simply running side-by-side inside this one web app that acts like a J2EE container. Is that possible? Something like a war virtualization app?

  • Where to store global variables like file paths in java ?

    - by Jules Olléon
    In my application I use some icons. Where should I store the path of the directory containing those icons ? The icons are used in different classes so it doesn't really make sense to store them in one of those classes in particular. I read that global variables are evil, but is it acceptable to use a class (eg Commons) containing only public static final fields to store this king of data ? What solution is used in professional applications ?
