What's with underscores starting names?

This has long baffled me.
What is with variable names, file names, and method names (those in regards to programming) starting out with an underscore? Is it some scheme of which I'm unaware?
_print()
what's that all about??
why do files often start with underscores?! WHY?!!?

A convetion used by C programmer were to have something like overloading using _ infront of methods, even two underscores.
The _ underscore highlights the method as being different.
It does not conform to the Java Style code convesion but is allowed.

Can I migrate printers with underscores in name?

I was wondering if it was possible to use the migration tool to migrate
printers and their profiles that have underscores in their names from oes2
sp2 to oes11?

I can't swear on it, but I and my customers have migrated so many
printers, I'm 99,9999% certain there have been some with underscores.

What comes with the Start Trek Into Darkness pre-order?

I am a little excited about ordering this moving but confused as to what comes with the pre-order. Does the previous ten movies come with the pre-order or is there an extra bundle you have to buy?

It will just be that one film. If you are in the US then you can get the first 10 films as a bundle for $49.99 :

What's with all the "name"s-short, long, user, computer?

I'm a long time Mac user but not lots of experience with multiple user accounts.
Trying to migrate from MB with one account to MBA; on about the 7th or 10th erase & install. Various methods of getting the data over are not working.
I'd like to have a new "home" account name, but the more I read the more confused I'm getting-there are so many different "name"s in the sharing/accounts windows I'm not sure if they are variations of each other or all different. Is there a table somewhere that tells the meaning of/difference among
short name
long name
home folder name
computer name
user name
account name
etc?
Apparently I can't migrate MB=MBA into a new short name, so have to do some trickery with advanced settings, or migrate then make a new account, drag/copy/from then delete the old account. What junk!
You'd a thunk Apple would know people would want to migrate a home folder to new machine and change the name of it along the way.
Phew. Not impressed so far with the ease of transition to MBA. 3 days in the works now.

Please look over http://pondini.org/OSX/Setup.html towards the bottom where he discusses that. Once you have the data moved into the account you want you can remove the account you don't want by using the System Preferences - Users & Account. The remaining account must be an administrators account though.

Perhaps this might be helpful:
https://addons.mozilla.org/en-US/firefox/addon/opendownload-10902/
It allows executables in Firefox to be run - it is an extenstion, though, so it must be installed in Firefox before your page will work.
Another option is this solution, but it will still require a manual change in Firefox:
http://forums.mozillazine.org/viewtopic.php?f=19&t=803615
Or this: http://stackoverflow.com/questions/6472435/running-exe-in-firefox-why- do-i-get-an-error
However, you will still have problems with getting it to work cross-browser. Honestly, browsers are not supposed to have access like that to the client side file system, which absolutely makes sense for the web.
That is why you may have to approach the solution from a different angle - perhaps create a server side cloud version of your application(s) which can be easily accessed and run by your family members. I believe you used C to develop the applications? Although I have no experience with this framework, Wt might be a solution to convert your projects to server side applications:

[SOLVED] Find and replace quotes with underscores in file names

I was looking to replace all of the quotes in file names in a directory with underscores. I seem to be having a problem doing so, though. Running the find command:
find . -name '*[\`\'\"]*' -exec sh -c "mv -i '$0' '${0//[\`\'\"]/_}'" {} \;
I get a > inviting me to continue the command. What am I doing wrong?
Last edited by gogi-goji (2010-01-03 02:19:13)

@lolilolicon: yeah the -exec part does give another level of quotes, so you can run into trouble with scripts inside -exec.
I didn't know you could give {} as an argument after sh -c and $0, that solves the problem of not knowing which quotes to use around it in the -exec part.
$ find -mindepth 1 -exec sh -c 'mv -v --backup=t "$0" "$(echo "$0" | sed s/[\\x27\"\`]/___/g)"' {} \;
mv: `./a b' and `./a b' are the same file
`./\'' -> `./___'
`./\'"\'' -> `./_________'
mv: `./$0' and `./$0' are the same file
mv: `./a' and `./a' are the same file
mv: `./$(echo crash)' and `./$(echo crash)' are the same file
`./"' -> `./___' (backup: `./___.~1~')
`./\'\'\'' -> `./_________' (backup: `./_________.~1~')
Or with the other substitution method, it doesn't interpret \x27 (you could use $(echo -e \\x27) or you have to use ...'\\\''...
$ find -mindepth 1 -exec sh -c 'echo mv -v --backup=t "$0" "${0//['\\\''\"\`]/___}"' {} \;
$ find -mindepth 1 -exec sh -c 'echo mv -v --backup=t "$0" "${0//[$(echo -e \\x27)\"\`]/___}"' {} \;
mv -v --backup=t ./a b ./a b
mv -v --backup=t ./' ./___
mv -v --backup=t ./___ ./___
mv -v --backup=t ./'"' ./_________
mv -v --backup=t ./$0 ./$0
mv -v --backup=t ./___.~1~ ./___.~1~
mv -v --backup=t ./a ./a
mv -v --backup=t ./$(echo crash) ./$(echo crash)
mv -v --backup=t ./_________ ./_________
mv -v --backup=t ./" ./___
mv -v --backup=t ./''' ./_________
mv -v --backup=t ./_________.~1~ ./_________.~1~

Under Data Marts folder, what is the datasource starting with 8?

hello BW gurus,
Run rsa1 -> Source Systems, then pick the BW system itself as the client, under folders BW DataSources -> Business Information Warehouse -> Data Marts, we can see some datasources or infosources starting with 8, how these datasouces get created and what are the purpose of them?
We know that the datasource starting with 7 means the export datasource generated from PSA, but have no idea what is for datasource starting with 8. Anyone's explanation is greatly appreciated!

Hi Kevin,
The DataSources starting with 8 are the datamart data sources, or Export DatSources. This means that they would supply data from the BW system to the BW system.
You will notice that the name is 8DataTarget, where DataTarget could be like an ODS object or an InfoCube. This means that data from this ODS or InfoCube can be updated to other data targets in the BW system using update rules.
You can generate the Export datasource from the context menu of a data target.
Hope this helps...

Welcome to the Apple community.
iTunes and iCloud and different accounts, you will need to delete both accounts from your device before adding the new details in their place.
For iCloud go to settings > iCloud, scroll down and hit the delete button. You can then sign back in using your correct details. For iTunes go to settings >store, tap your account ID and then sign out, you can then sign back in using your correct Apple ID.

What causes the full file name to be listed with bookmarks?

Good morning! What drives RH to list the full file name in
bookmark code in some files, and in others its just the
href="#bookmark? If you change the file name...all the bookmark
links with full file names break. Am I doing something wrong when I
created them...? Not sure how that's possible...but something is
driving this! Any helpful hints from the masters online?

Hi Teri
It's been my experience that if you elect to create a link
from inside the topic to a bookmark, and you choose the bookmark
from the dialog, you end up with a link that simply has the hash
and the bookmark (#Bookmark).
Where you see the file name preceding the hash and the
bookmark, odds are the link was created by the user clicking the
bookmark in either the Project Manager or the Topic List and
dragging from there to create the link. When links are created in
that fashion (I'm addicted to creating links that way myself - it's
like crack to me - if I knew what that was like LOL) RoboHelp
creates the link with the file name (FileName.htm#Bookmark).
Cheers... Rick

Do you have current backups?
Those symptoms could indicate a failing Hard drive. If it dies, all your documents go with it unless you have Backups.
I have had very good luck with physical and battery problem diagnosis at the Genius Bar. Those guys put their hands (and their ears) to these machines, all day every day, and they know immediately what all those sounds mean.

Problems with replace file name with starting and ending Bates number

When applying Bates numbers to a set of Acrobat pdf files I am unable to replace file names with the starting and ending Bates number. This is important
for me in a legal application.
The Bates numbers are applied to each page of each of file without any problem as required.
The Bates log file indicates that the files have been renamed as I wanted.
I am running Adobe Acrobat Professional 9 with the update to 9.1.9 and Windows XP Service Pack 3 (the last or current service pack)
In all other respects Adobe Acrobat 9 is running to my satisfaction.
Has anyone else had this problem and found a solution?
HRKExon

Thanks for asking the question, I hadn't heard of Bates numbers before and this gave me a chance to look up something new.
When I googled for ' bates number legal index ' I found this document:

Maybe that will help.
