I need to write a small R script for people who never used R before that imports a file and does some things with it. I would like to minimize user input as much as possible, and since assigning the file-path is basically all the user input required I was wondering, is it possible to get a popup screen (basically your usual "open file" screen) allowing someone to select a file (import the name as string in R or something)?
The file.choose function performs this, eg:
fname <- file.choose()
source(file.choose())
You may also want to look at choose.files (for multiple files) and choose.dir (for just selecting a directory path).
The tcltk package gives you tk_choose.files.
If you want to go beyond file choosers then you can use the package to build user interfaces.
It's worth mentioning rChoiceDialogs::rchoose.files. I'm not completely sold yet, but they advertise it as being completely cross platform and fixing the annoying problem common to choose.files and tk_choose.files of popping up behind other windows. See their vignette here.

It's a long shot, but does anyone know of a working method to get the associated icon location (= path to an exe/dll/ico file) and ID for a given filename with WinAPI. The point is to create a shortcut to another file (which may or may not be of the same file type) and set THIS exact icon, overriding its default one, presumably with IShellLink::SetIconLocation.
Things that don't work:
-ExtractAssociatedIcon
-SHGetFileInfo
-IExtractIcon
Return random crap with GIL_NOTFILENAME flag set for any of the default file types I've tried (like txt).
There seem to be several topics on SO about this sorta thing, with answers/non-answers suggesting one of the above. This one [1] appears most close to being informative. Their preferred method doesn't work either, but their other notes gave me the hint to try using the registry.
So for the time being, I wrote my own function that uses the registry [2], but it's also not perfect: in some cases, the registry stores 'positive icon IDs' that cannot, it seems, be used with SetIconLocation.
Honestly didn't expect this to be such a year 2023 problem
You don't need to call IShellLink::SetIconLocation if you don't want to override the targets default icon. Just point the shortcut to a .txt file and the shortcut automatically gets the correct icon.
Positive icon IDs most certainly can be used with SetIconLocation, that is the common case. Are you calling PathParseIconLocation?
GIL_NOTFILENAME is just something you have to accept, it usually means the icon comes from the system image list. The shell is mainly interested in going from a file/type to a HICON, not the other way around. The icon for a file may even be dynamic if it is implemented by a shell extension.
You can add AssocQueryString to the list of functions to try that will never work 100% of the time...
Good day, everyone. I have that task assigned which consists in creating simple installscript-only project, that should have 2 windows: first will prompt user to enter a path and create text file in this specified location, while second will promt for text input and save anything user writes into this text file.
Funny point is that I have small installshield experience (completed tutorials... well, yeah, that's all) and very little programming experience on top of that. As far as i understand, I should first create two custom dialog windows (for example by cloning them from standard ones), then create .rul files with functions, determining behavior for each. After which, include them into main setup.rul and call functions at specific point of time.
Question is - what exact dialog windows/functions/points of time will be best for such task? For reference i searched into "Serial Number Validation Sample Project" but, honestly, the way it customized default window is just confused me even more... So, please, can anybody help? Thank you.
For future reference, here's working solution.
Asked that same question at flexera forums, and here's what I got:
Off the top of my head (without InstallShield handy to check this) 1)
Create an InstallScript project, just accept all of the defaults in
the new project wizard unless you want to add localization or
something. 2) Your description implies that you do not need
maintenance (repair, modify, uninstall) support. If correct go to
Project\Settings and on the Maintenance tab select 'no uninstall or
maintenance'. 3) You can put your code at the top of the
OnFirstUIBefore function and then call Exit so that the rest of that
default code is never executed, since you are not installing anything.
As part of your InstallShield IDE, in the Start menu (for IS2012
Spring) is a tool that demonstrates all of the built in dialogs. You
can look through those choices and select the dialog that is best for
your situation. It sounds like you want to:
Call AskPath or SdAskDestPath (there are several other possibilities)
Then call AskText and save that string.
If you need to make layout or text changes to the default dialogs look
at your Dialogs view and select which ever dialog you selected above
and edit it. (If you decide to use skins make sure you select the skin
before you make any dialog layout changes.)
Then do something similar to the functional body of the WriteLine
example http://kb.flexerasoftware.com/doc/Helpnet/installshield14langref/LangrefWriteLine_Example.htm
The actual WriteLine example function prototype is for a MSI custom
action which is not what you want. Ignore the function protoype and
just use the code in your project to create the file at the path you
already collected and write the line of text that you collected.
Then call Exit;
(big thanks to user phill_mn for that answer)
And here's the code for setup.rul:
#include "ifx.h"
function OnFirstUIBefore()
number nvFileHandle;
string svResult;
string szTargetPath, szFeatures;
BOOL bLicenseAccepted;
begin
AskPath ("Please choose a path where text file will be saved","c:\\",szTargetPath);
MessageBox("File yourtext.txt wiil be created or overwritten at " +szTargetPath, INFORMATION);
AskText ("Please enter some text to save into that file", "Text goes here", svResult);
OpenFileMode (FILE_MODE_APPEND);
if (CreateFile (nvFileHandle, szTargetPath, "yourtext.txt") < 0) then
MessageBox ("Creating failed.", SEVERE);
abort;
else
if (WriteLine(nvFileHandle, svResult) < 0) then
MessageBox ("Writing failed.", SEVERE);
else
MessageBox ("Success.", INFORMATION);
endif;
endif;
CloseFile (nvFileHandle);
Do(EXIT);
return 0;
end;
I have 90 profiles,and a bunch of record types. Business wants to know who has access to a current record type (picklists..)
the only way i know how to do this, is to go profile by profile and check the Record Type Settings and see if it's listed.
is there a way to just generate a list or something? either through the point and click or apex?
EDIT:
I tried doing a search on the .profiles but eclipse doesn't support multi-line searches. Though it does support regexes i can't get my regular expression right, OR eclipse doesn't like me. Given my poor programming skills (and how I yell at my computer) it might be the latter. This is the string I want to search on.
<recordType>Event.RTEvent</recordType>
<visible>false</visible>
For something like this, I find that Notepad++ is a huge help. It supports multi-line searches if you enable the extended search mode (a simple radio button at the bottom of the Find menu), allowing you to grab line breaks (\r, \n, etc.). Pretty simple to do this across all of your profiles as well by navigating to the profiles folder of the Eclipse project in Windows Explorer, selecting all files, then right-click and select "Edit with Notepad++". Once they're all open, hit ctrl-F, enable the extended search mode, and search for something like this:
Event.RTEvent</recordType>\n <visible>false
Note that you may need to adjust the number of spaces after the \n depending on how far the data is indented. Click "Find All in All Opened Documents", and it'll give you a list of all occurrences of that string in your profiles files.
I am using the Drupal 7 Migrate module to create a series of nodes from JPG and EPS files. I can get them to import just fine. But I notice that when I am done importing them if I look at the nodes it creates, none of the attached filefield and thumbnail files contain filename information.
Upon inspecting the file_managed table I see that both the filename and filemime fields are empty for ONLY the files that I attached via the migrate module. This also creates an issue with downloading the files.
Now I think the problem has to do with the fact that I am using "file_link" instead of "file_copy" as the file operation I specify. The problem is I am importing around 2TB (thats Terabytes) of image files. We had to put in a special request with Rackspace just to get access to that much disk space on our server. So I can't go around copying from one directory to the next because of space issues. So "file_link" seems like the obvious choice.
Now you probably want to see how I am doing this exactly, so here is the code snippet:
$jpg_arguments = MigrateFileFieldHandler::arguments(NULL,
'file_link', FILE_EXISTS_RENAME, 'en', array('source_field' => 'jpg_name'),
array('source_field' => 'jpg_filename'), array('source_field' => 'jpg_filename'));
$this->addFieldMapping('field_image', 'jpg_uri')
->arguments($jpg_arguments);
As you can see I am specifying no base path (just like the beer.inc example file does). I have set file_link, the language, and the source fields for the description, title, and alt.
It is able to generate thumbnails from the JPGs. But still missing those columns of data in the db table. I traced through the functions the best I could but I don't see what is causing this. I tried running the uri in the table through the functions that generate the filename and the filemime and they output just fine. It is like something is removing just those segments of data.
Does anyone have any idea what this could be? I am using the Drupal 7 Migrate module version 2.2. It is running on Drupal 7.8.
Thanks,
Patrick
Ok, so I have found the answer to yet another question of mine. This is actually an issue with the migrate module itself. The issue is documented here. I will be repealing this bounty (as soon as I figure out how).
A friend of mine is now building a web application with J2EE and Struts, and it's going to be prepared to display pages in several languages.
I was told that the best way to support a multi-language site is to use a properties file where you store all the strings of your pages, something like:
welcome.english = "Welcome!"
welcome.spanish = "¡Bienvenido!"
...
This solution is ok, but what happens if your site displays news or something like that (a blog)? I mean, content that is not static, that is updated often... The people that keep the site have to write every new entry in each supported language, and store each version of the entry in the database. The application loads only the entries in the user's chosen language.
How do you design the database to support this kind of implementation?
Thanks.
Warning: I'm not a java hacker, so YMMV but...
The problem with using a list of "properties" is that you need a lot of discipline. Every time you add a string that should be output to the user you will need to open your properties file, look to see if that string (or something roughly equivalent to it) is already in the file, and then go and add the new property if it isn't. On top of this, you'd have to hope the properties file was fairly human readable / editable if you wanted to give it to an external translation team to deal with.
The database based approach is useful for all your database based content. Ideally you want to make it easy to tie pieces of content together with their translations. It only really falls down for all the places you may want to output something that isn't out of a database (error messages etc.).
One fairly old technology which we find still works really well, is to use gettext. Gettext or some variant seems to be available for most languages and platforms. The basic premise is that you wrap your output in a special function call like so:
echo _("Please do not press this button again");
Then running the gettext tools over your source code will extract all the instances wrapped like that into a "po" file. This will contain entries such as:
#: myfolder/my.source:239
msgid "Please do not press this button again"
msgstr ""
And you can add your translation to the appropriate place:
#: myfolder/my.source:239
msgid "Please do not press this button again"
msgstr "s’il vous plaît ne pas appuyer sur le bouton ci-dessous à nouveau"
Subsequent runs of the gettext tools simply update your po files. You don't even need to extract the po file from your source. If you know you may want to translate your site down the line, then you can just use the format shown above (the underscored function) with all your output. If you don't provide a po file it will just return whatever you put in the quotes. gettext is designed to work with locales so the users locale is used to retrieve the appropriate po file. This makes it really easy to add new translations.
Gettext Pros
Doesn't get in your way while coding
Very easy to add translations
PO files can be compiled down for speed
There are libraries available for most languages / platforms
There are good cross platform tools for dealing with translations. It is actually possible to get your translation team set up with a tool such as poEdit to make it very easy for them to manage translation projects
Gettext Cons
Solves your site "furniture" needs, but you would usually still want a database based approach for your database driven content
For more info on gettext see this wikipedia page
They way I have designed the database before is to have an News-table containing basic info like NewsID (int), NewsPubDate (datetime), NewsAuthor (varchar/int) and then have a linked table NewsText that has these columns: NewsID(int), NewsText(text), NewsLanguageID(int). And at last you have a Language-table that has LanguageID(int) and LanguageName(varchar).
Then, when you want to show your users the news-page you do:
SELECT NewsText FROM News INNER JOIN NewsText ON News.NewsID = NewsText.NewsID
WHERE NewsText.NewsLanguageID = <<Session["UserLanguageID"]>>
That Session-bit is a local variable where you store the users language when they log in or enters the site for the first time.
Java web applications support internationalization using the java standard tag library.
You've really got 2 problems. Static content and dynamic content.
for static content you can use jstl. It uses java ResourceBundles to accomplish this. I managed to get a Databased backed bundle working with the help of this site.
The second problem is dynamic content.
To solve this problem you'll need to store the data so that you can retrieve different translations based on the user's Locale. (Locale includes Country and Language).
It's not trivial, but it is something you can do with a little planning up front.

thats what we apply it to. Our apps are all PHP, but gettext has a long heritage.
Looks like there is a good Java implementation
Tag libraries are fine if you're using JSP, but you can also achieve I18N using a template-based technology such as FreeMarker.
