I am using Flex, Flash Builder 4.5 and Extension Builder 2.0.0 and I use the "nochump ziplib" library to generate a ZIP file. I want to create a new folder in created ZIP file, but I can't find such function function in the "nochump" library.
Can anyone please tell me if there is any function to add new folder in a ZIP file or a library which can help me do this?
The directories are not first-class citizens in the ZIP format.
The archive is built from "entries" - plain files with their relative locations to the "central directory" (the "root" of the archive). This means that the ZIP file is composed from entries like "pictures/1.jpg", "doc/old/1.txt" etc. You don't have separate entries for the "pictures", "doc" or "doc/old" directories.
You can't create a new directory directly. Instead of creating a new directory first (such as "newDir") you may want to create a file (entry) inside instead (such as "newDir/1.txt") and "newDir" will appear as directory when you open the resulting ZIP file.
If you insist on having an empty directory in the archive, you may try the hacky way - adding entries like "newDir/." with zero length. But this may not work with your library.
The Wikipedia article for the ZIP format has all the theory explained pretty well.

you can use the bootstrap configurator (http://getbootstrap.com/customize/) to configure your own bootstrap version (e.g. set the variables like #grid-float-breakpoint to configure the navbar collapse point). I want to use this feature within my project which is based on gwt using https://github.com/gwtbootstrap3/gwtbootstrap3based.
I managed to create my download my configured bootstrap.zip using the method above.
The zip contains (as expected):
\bootstrap\js
\bootstrap\css
\bootstrap\fonts
just as GWTBootstrap3 project
gwtbootstrap3-0.9.3\org\gwtbootstrap3\client\resource\js
gwtbootstrap3-0.9.3\org\gwtbootstrap3\client\resource\css
gwtbootstrap3-0.9.3\org\gwtbootstrap3\client\resource\fonts
So I tried to replace the bootstrap files out of css with the genereated bootstrap files.
But then I recognized that in the GWTBootstrap3 project there are files named *.cache.min.
How / when are these files generated? This is explained already here: GWT Caching Concept
So obviously we want to replace the bootstrap files to remain "cache"d.
Can you please forward me a step-by-step description of how to use bootstrap configurator along with the current GWTBootstrap3 project , i.e. what files need to be replaced?
What I already tried (with no success):
0.) Create a bootstrap.zip with the online configurator and download it
1.) Rename gwtbootstrap3-0.9.3.jar to gwtbootstrap3-0.9.3.zip
2.) Extract
3.) Replace bootstrap-3.3.6.min.cache.css with bootstrap.min.css (from the configurator) and replacing meaning the bootstrap.min.css is renamed to bootstrap-3.3.6.min.cache.css
4.) Put all files from bootstrap.zip into the respective directory and renaming it accordingly as explained in 3.) to effectively replacing the original file
5.) zip and rename it again to gwtbootstrap3-0.9.3.jar
6.) replace the lib in my project
But after doing so I continuously get the compiler errors:
Package org.gwtbootstrap3.client.ui cannot be found.
Any help greatly appreciated
Best regards

I can provide an answer which should work for most of the configuration changes. First of all I had to learn that renaming gwtbootstrap3-0.9.3.jar to gwtbootstrap3-0.9.3.zip then unzip, rezip and rename to jar does NOT WORK!!!
So here is a step by step tutorial of how to configure your bootstrap and use it with gwtbootstrap3.0.9.3 . I am not sure this will work for future editions but it should work for bootstrap3.
Configure and download your new bootstrap
https://github.com/gwtbootstrap3/gwtbootstrap3based.
Unzip your new bootstrap, this will provide the subdirectories css,
fonts and js. So you will have something like bootstrap/css etc.
Now copy your "old" gwtboostrap3.0.9.3 jar to the base directory, so
that the bootstrap.zip and the jar lie in the same directory.
From the commandline issue jar xf gwtbootstrap3.0.9.3.jar which will
create the 2 directories META-INF and org in your directory
Move into org\gwtbootstrap3\client\resource\css
Copy the FILENAME (not the file!!!). In my gwtbootstrap version the
file is called "bootstrap-3.3.6.min.cache.css".
Rename the file bootstrap/css/bootstrap.min.css to
bootstrap/css/bootstrap-3.3.6.min.cache.css and REPLACE
org\gwtbootstrap3\client\resource\css\bootstrap-3.3.6.min.cache.css
with bootstrap/css/bootstrap-3.3.6.min.cache.css
Rename the file bootstrap\css\boostrap-theme.min.css to
boostrap\css\bootstrap-theme-3.3.6.min.cache.css and REPLACE
org\gwtbootstrap3\client\resource\css\bootstrap-theme-3.3.6.min.cache.css
with bootstrap\css\bootstrap-theme-3.3.6.min.cache.css
I left out the fonts directory because my changes did not change
anything with the fonts
Rename bootstrap\js\bootstrap.min.js to
bootstrap\js\bootstrap-3.3.6.min.cache.js and REPLACE
org\gwtbootstrap3\client\resource\js\bootstrap-3.3.6.min.cache.js
with bootstrap\js\bootstrap-3.3.6.min.cache.js
In the basedirectory (where the bootstrap directory lies) issue from
the commandline: "jar xf gwtbootstrap3.0.9.3.jar META-INF org". This
should produce your new gwtbootstrap3.0.9.3.jar lib
In your project replace the old gwtbootstrap3.0.9.3.jar with the new
lib.
In case you get lots of java errors telling you it cannot find the classes you mixed up the paths. Please let me know if this worked out for your. Perhaps someone can provide a shellscript to automate the whole process.
One tip: Customizing your bootstrap gives you more control, e.g. for handling the point at which the navbar becomes uncollapsed (at the configuration page look for the key called "#grid-float-breakpoint"). Don't forget to enter a value suitable for you (mine was 800px). Don't forget to add px at the end!!
I almost finished two Orchard projects and now I want to focus on translation.
Everywhere I used the Helper class T("") like T("Some english text").
Is there a Orchard 1.8 compatible module that lists all of my translation entries in the Admin menu and lets me create a new translation for it?
Or maybe any helper that lists the translations and writes it into a file?
There is a module Translation Manager (part of Vandelay Industries module in gallery) that can extract strings from source code and generate .po files.
Docs: Contributing files for third party modules
Contributing files for third party modules
... you can generate po files for it
using the Translation Manager module.
From an Orchard command line, type the following command (for the
example of the Bing.Maps module):
extract default translation /Extensions:Bing.Maps /Output:\temp
This will create a new Orchard.en-us.po.zip file with the strings for
the module. The command looks at the source code for the module and
creates entries for T-wrapped strings, manifest strings and everything
that should be localizable.
I've created an installer package based on the Qt installer framework with multiple components.
I needed to install each component in the appropriate directory.
Is it possible to specify the target directory for the individual component? I am referring to something like this:
var appData = installer.environmentVariable("AppData");
if (appData != "")
component.setValue("TargetDir", appData+ "/MyComponent");
Thank you in advance.
This question has already been answered, but I thought I would add a more detailed answer.
The documentation states that "for each component, you can specify one script that prepares the operations to be performed by the installer."
The Qt installer framework QtIFW comes with a set of examples, one of which is called modifyextract. Using this, I modified my package.xml file to include the line
<Script>installscript.qs</Script>
I then added a file installscript.qs to my package meta directory with the following content
function Component()
{
}
Component.prototype.createOperationsForArchive = function(archive)
{
// don't use the default operation
// component.createOperationsForArchive(archive);
// add an extract operation with a modified path
component.addOperation("Extract", archive, "#TargetDir#/SubDirectoryName");
}
The files in the package data folder were then installed in the subfolder SubDirectoryName
You need this based on the documentation:
Extract "Extract" archive target directory Extracts archive to target directory.
In my case, the component.addOperation("Extract", ... line resulted in extracting to #TargetDir#.
Instead, use one of the 'Operations> options in the Package.xml file.
If I use the write method, where will these files be written? Example:
write(results, file="myFile.csv", ncolumns=1)
I don't specify a full path so I assume it's writing to some default directory. I checked program files, but it's not there. Suggestions on where to look?
If you type from within your R session:
getwd()
You should be able to retrieve your current working directory, that's the place where the files should be saved to.
You can also choose to set your workspace to a location of your desire:
setwd('C:/Users/.../Documents/R/Scripts')
Files you save will automatically be written to this new location.
I am having trouble in storing the files in a string array from a directory in c++, using System::IO::Directory::GetFiles in c++
Also would like to know if we could copy an entire folder to a new destination/ in c++ like given in http://www.codeproject.com/KB/files/xdirectorycopy.aspx for c#
You can store the file names from a directory in a managed array like this:
System::String ^path = "c:\\";
cli::array<System::String ^>^ a = System::IO::Directory::GetFiles(path);
Console::WriteLine(a[0]);
Console::ReadKey();
As for how would you copy an entire folder... Simply recurse from a given root directory creating each directory and copying the files to the new location. If you are asking for code for this, then please say so, but at least try to figure it out for yourself first (i.e. show me what you have so far).
Check out the file listing program in Boost::FileSystem: http://www.boost.org/doc/libs/1_41_0/libs/filesystem/example/simple_ls.cpp. They iterate over all files, printing the paths, but it's trivial to store them instead.
Assuming you're on Win32, you're looking for the FindFirstFile and FindNextFile APIs.
C/C++ does not define a standard way to do this, though Boost::Filesystem provides a method if you need cross platform support.
