I am accessing an IMAP server using Python imaplib.
I am doing this for three different mailboxes box1#mydomain.de, box2#mydomain.de, other#otherdomain.de.
In each case, I want to access the folder INBOX.
In each case, a folder listing confirms that this folder exists at the top level:
b'(\HasNoChildren) "." "INBOX"'
All three mailboxes are at the same ISP and are accessed via the same IMAP server name.
The code is working fine for box2 and other.
For box1, however, it fails with this error message:
Couldn't select folder A/INBOX: NO / [CANNOT] Non-supported characters in the mailbox name
I have determined that A will always be the name of the first subfolder:
b'(\HasChildren) "." "A"'
If I rename A to Z, the next existing subfolder will take the place of A in the error message.
Question 1: Why is the server prepending a subfolder when I ask for INBOX?
I gather that the error message tells me that the / in the name is a problem,
because the server uses . as a folder name separator?
Question 2: Why is the server so silly to construct a name it will not accept?
Question 3: What can I do to repair the mailbox? (I have no control of that server.)
Question 4: Does anybody know a programmer who has ever written code using IMAP and thinks IMAP is a good protocol? (semi-serious question)
Thank you #Max, your request for code did the job. I used the debugger and found the problem in the framework I am using:
I am using a subclass of mailprocessing.processor.imap.ImapProcessor that turns what is meant as a command-line tool into an API for my script.
ImapProcessor, unless told otherwise, by default uses this logic in its constructor:
# This should catch at least some of these weird IMAP servers
# that store everything under INBOX. Use --folder-prefix for
# the rest for now.
if cmd_prefix is None and root_has_children:
self.prefix = root_folder
and this root_folder is simply the first folder in the folder list,
in my case A.
If I construct my object as ImapProcessor(..., folder_prefix=""), all works as intended.
(Overall, mailprocessing has nice functionality, but also a number of weird decisions, plus two bugs to get over.)
So the answers to my questions 1, 2, 3 are "it doesn't", "it isn't", "no repair needed". Instead, my code simply called a functionality I had not expected to exist.

I get the version number of the firefox from the applications.ini.
Then I hardcoded that between date #### and #### v35 is release. So now based on this and the current date and version from applications.ini I figure out the channel of other builds.
But now I want to get the localized name of the channel.
So for example I'm using beta channel and from this build I want to get the localized name of "Nightly" in chineese, so it has the chineese characters, and word for nightly in chineese. Can this also be obtained from the applications.ini? Is [App] -> Name localized in applications.ini?
This is the applications.ini method: https://ask.mozilla.org/question/705/detect-if-auroranightlybetanormal-and-get-paths/ (credits to #paa)
EDIT
i discovered this file: OS.Path.join(Services.dirsvc.get('XREExeF', Ci.nsIFile).parent.path, 'defaults', 'pref', 'channel-prefs.js')
its contents is the following:
//#line 2 "c:\builds\moz2_slave\rel-m-beta-w32_bld-00000000000\build\browser\app\profile\channel-prefs.js"
/* This Source Code Form is subject to the terms of the Mozilla Public

pref("app.update.channel", "beta");
Is this a reliable check? Does this channel-prefs.js file exist for all builds as soon as they are installed?
Is this a reliable check?
Not really. There used to be channel switcher add-ons, and in theory the user can change this pref (although at the moment this is not sufficient to really switch the channel I think).
Does this channel-prefs.js file exist for all builds as soon as they are installed?
Yes, for now. But this is an implementation detail. There is no guarantee that the file won't be moved or renamed later, or merged with another file.
Can this also be obtained from the applications.ini?
The localized name? I didn't even know there was one... I thought it was called e.g. "Nightly" in all locales like it was a (product) name. But yeah, it is theoretically possible to localize that string. It is not available from the ini file, though.
I wouldn't poke in application.ini anyway, and instead just use Services.appinfo.defaultUpdateChannel
But now I want to get the localized name of the channel.
Since you're in a running Firefox instance already (judging from your OS.File code), you should use the string bundle service to load chrome://branding/locale/brand.properties and get the brandShortName or brandFullName string from there.
I am converting a VB6 application to VB.NET. In the code I am converting, it seems that the developer found the applications path two separate ways. However, it appears that he expects the two methods to produce different results.
Simple question:
What is the difference between calling these two lines of code:
strAppDataPath = CreateObject("Shell.Application").
NameSpace(ssfLOCALAPPDATA).Self.Path
and
strAppDataPath = App.Path
Explanation:
This is the code in question:
strAppDataPath = CreateObject("Shell.Application").
NameSpace(ssfLOCALAPPDATA).Self.Path
strAppDataPath = strAppDataPath & "\DataFolder\"
If (Not objFileSystem.FileExists(strAppDataPath & strAppDataFile)) Then
If (objFileSystem.FileExists(App.Path & strAppDataFile)) Then
...
End If
End If
The application's path is appended with \DataFolder\, and stored in the String strAppDatapath.
We check if the file strAppDataFile does not exist in strAppDatapath. Followed by checking if the file does exist in App.Path.
The concept behind what is going on makes sense to me: If the file doesn't exist in the subfolder, and if the file exists in App.Path, then do .... What I do not understand is why they didn't use one of the method for finding the application's path exclusively.
They don't point to the same path.
App.Path: Path where the currently executing EXE/DLL resides.
CreateObject("Shell.Application").NameSpace(ssfLOCALAPPDATA).Self.Path: Will point to the local (non-roaming) app data user folder. Same as the value in (user) environment variable LOCALAPPDATA.
Since Windows XP, the roaming & local app data paths are preferred places to store user settings and files (instead of the probably rights-restricted app folder).
So what the code does, is:
Look for strAppDataFile in %LOCALAPPDATA%\DataFolder\ (e.g. where "%LOCALAPPDATA%" could point to "C:\Users\UserName\AppData\Local\" on Windows Vista/7)
If not found, look for the same file in the application folder.
Please note that preferably applications should create an application specific sub-directory in local/roaming app data, e.g. use something like:
strAppDataPath = strAppDataPath & "\" & App.ProductName & "\DataFolder\"
' NOTE: Make sure to set the "Product Name" entry in the version information
' of the project settings
that could resolve to something like
"C:\Users\UserName\AppData\Local\My Application\DataFolder\"
My guess is that when the program is installed per-machine, a per-user location under LocalAppData is used. However during development or when installed per-user or as a portable application the application folder is used.
Some programmers use something like the code in question, while others make the decision by comparing App.Path against the ssfPROGRAMFILES path to determine the environment. The latter is probably preferable for a number of reasons but in the degenerate case where only one instance of the program exists on a machine they're equivalent.
I'm planning to do a program with Lua that will first of all read specific files
and get information from those files. So my first question is whats the "my documents" path name? I have searched a lot of places, but I'm unable to find anything. My second question is how can I use the first four letters of a file name to see which one is the newest made?
Finding the files in "my documents" then find the newest created file and read it.
The reading part shouldn't be a problem, but navigating to "my documents" and finding the newest created file in a folder.
For your first question, depends how robust you want your script to be. You could use Lua's builtin os.getenv() to get a variety of environment vars related to user, such as USERNAME, USERPROFILE, HOMEDRIVE, HOMEPATH. Example:
username = os.getenv('USERNAME')
dir = 'C:\\users\\' .. username .. '\\Documents'
For the second question, there is no builtin mechanism in Windows to have the file creation or modification timestamp as part of the filename. You could read the creation or modification timestamp, via a C extension you create or using an existing Lua library like lfs. Or you could read the contents of a folder and parse the filenames if they were named according to the pattern you mention. Again there is nothing built into Lua to do this, you would either use os.execute() or lfs or, again, your own C extension module, or combinations of these.
I am trying to create a setup project for a Windows Service. I've followed the directions at http://support.microsoft.com/kb/816169 to create the setup project with no trouble.
I want to be able to get a value during the installation in order to update the app.config with the user's desired settings. I added a Textboxes (A) dialog to retrieve the values. I set the Edit1Property property to "TIMETORUN", and in my Primary Output action's CustomActionData property I put in the following: /TimeToRun="[TIMETORUN]\". So far so good. Running the setup I can retrieve the TimeToRun value from the Context.Parameters collection without issue.
In order to locate the app.config I need to also pass in the value of the TARGETDIR Windows Installer Property to my custom action. This is where things begin to fall apart. In order to achieve this, the above CustomActionData must be altered like so: /TimeToRun="[TIMETORUN]\" /TargetDir="[TARGETDIR]\". Now when I run the setup I get the following error message:
Error 1001. Exception occurred while initializing the installation.
System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Windows\SysWOW64\Files' or one of its dependencies. The system cannot
find the file specified.
If you google this problem you will inevitably find people having tremendous success by simply adding the trailing slash to the /TargetDir="[TARGETDIR]\" portion of the CustomActionData. This unfortunately does not solve my issue.
I tried so many different variations of the CustomActionData string and none of them worked. I tried logging to a file from my overridden Install method to determine where the breakage was, but no log file is created because it's not even getting that far. As the error indicates, the failure is during the Initialization step.
I have a hunch that it could be one of the dependencies that the setup project is trying to load. Perhaps somehow something is being appended to the CustomActionData string and isn't playing well with the TARGETDIR value (which contains spaces, i.e. "C:\Program Files\My Company\Project Name"). Again, this is another hunch that I cannot seem to confirm due to my inability to debug the setup process.
One further thing to mention, and yes it's another hunch, could this be an issue with Setup Projects on 64-bit version of Windows? I'm running Windows 7 Professional.
I'll provide names of the dependencies in case it helps:
Microsoft .NET Framework
Microsoft.SqlServer.DtsMsg.dll
Microsoft.SqlServer.DTSPipelineWrap.dll
Microsoft.SqlServer.DTSRuntimeWrap.dll
Microsoft.SQLServer.ManagedDTS.dll
Microsoft.SqlServer.msxml6_interop.dll
Microsoft.SqlServer.PipelineHost.dll
Microsoft.SqlServer.SqlTDiagM.dll
As you may glean from the dependencies, the Windows Service is scheduling a call to a DTSX package.
Sorry for the long rant. Thanks for any help you can provide.
The answer is so maddeningly simple. If the last argument in the CustomActionData is going to contain spaces and thus you have to surround it with quotes and a trailing slash, you must also have a space following the trailing slash, like this:
/TimeToRun="[TIMETORUN]\" /TargetDir="[TARGETDIR]\ "
The solution and explanation can be found here.
Had a similar issue. In my case, it was odd because my installer had ran successfully once, then I uninstalled my app via Add/Remove Programs successfully, did some coding (did NOT touch my CustomActionData string), and rebuilt my project and setup project. It was when I re-ran my MSI that I got this error.
The coding I had done was to bring in more values of more parameters I had been specifying in my CustomActionData string. That syntax for getting the parameter values (i.e. string filepath = Context.Paramenters["filepath"]), which was in my Installer class, was actually fine, but as I found out, the syntax of the later parameters I was now trying to get from my CustomActionData string had not been correct, from the very beginning. I had failed to add a second quote around one of those parameters, so nothing else could be obtained.
I was using the "Textboxes (A)" and "Textboxes (B)" windows in the User Interface section. A has 1 box, EDITA1, where I get the path to a file, and B has 2 boxes, EDITB1 and EDITB2, for some database parameters. My CustomActionData string looked like this:
/filepath="[EDITA1]" /host="[EDITB1] /port="[EDITB2]"
It should have been:
/filepath="[EDITA1]" /host="[EDITB1]" /port="[EDITB2]"
(closing quote on [EDITB1])
I am using the help-balloons plugin
I would like to use it parametrized. I mean, the messages should come from a properties file. In the documentation appears the following:
<g:helpBalloon code="user.name" suffix=".help"/>
In this last example, the code attribute is used to look up the balloon's title within the message bundle and then the suffix is added to the code (producing user.name.help in our example) as the key to be used for looking up the content of the balloon.
My question is:
Where should be located this properties file (message bundle)?
Can I have one message bundle per controller?
Luis
if you looked at the source code for the help balloon tag, it literally uses the grails interationalization code to render the message if given a key. http://fisheye.codehaus.org/browse/grails-plugins/grails-help-balloons/trunk/grails-app/taglib/HelpBalloonTagLib.groovy?r=45243
check out this page http://www.grails.org/doc/1.0.x/guide/10.%20Internationalization.html it tells you where and how to name the file for message bundles.
as for a message bundle per controller, it doesnt seem like you can (at least not apparent from the documentation). but you can hack it by prefixing the message key by the controller name, and thus use the same message bundle file (message.properties_ but still be able to namespace each message.
Where are the Resource bundles:
There is a directory under grails-app called i18n where all the generated resource files are placed, start looking there and see how they are used in the app.
You may be able to just place multiple message files for your controllers in there for organization, just be careful of reusing keys as I'm not sure how that will be handled off hand.
How to access them:
Maybe this will help I hope:
