Drawing line from existing one without joining

How can I draw a line from the endpoint of an existing line (snap to grid is on), without the lines being joined? Joining causes two problems for me:
1. The arrowhead at the end of the existing line moves to the end of the joined line, whereas I want the arrowhead in the middle of the combined line.
2. Even without entering isolation mode the new line gets joined to a line which belong to a group, thus becoming part of that group as well. This defies the use of grouping to create logically connected units.

while I agree in principle, on practice when clicking on end points with the pen tool most of the time I do want the paths to join but a lot of other times I do not. So, the best practical solution at least for me would be just holding the Spacebar when clicking on an end point to prevent joining without the need to click away and then drag in place. And they should make this an option in the Preferences for those who want to hold Spacebar only when joining.
The bigger problem is that with overlapping points and edges, Illustrator uses the stacking order and not the selected object when auto joining or adding points which is actually not practical in any case. For example if there are several lines starting at the same point, not the selected but the topmost line will be joined and with overlapping edges adding a point is impossible if the selected edge is not on the top.

Select from multiple tables without join statement

Hey Gurus,
I would like to make a select from a multiple tables to check if there is any reference to my data. I would like to do it with some elegancy, but I don't know how.
Is in abap sql possible to do it only with the select statement?
Or I was also think about a solution that I should fill some data structure with all of the tables which I want to select from and then just loop that data structure and do the select seperately from all of the tables. I just need to check if it founds some results, so no need to store it. If this solution would be fine what data structure should I use?
Or can tell me what would be the best for this?
My code for select from one table, which I want to make for multiple tables:
SELECT SINGLE id_kniznice FROM zbr_t_autori INTO wa_id
       WHERE id_kniznice EQ ls_extract-zview-id_kniznice.
     IF sy-dbcnt > 0.
       MESSAGE i000(zbr_msgc_lib).
       ls_extract-flags-vim_mark = '*'.
       MODIFY extract FROM ls_extract.
ENDIF.
Thank you for any posts.
Regards,
Robert

Read this topic:
For All Entries is NOT better than INNER JOIN in most cases
And this one:
inner join vs for all entries
Also that one:
Re: LOOP AT vs INNER JOIN
JOINs are really better than for all entries in most cases. Problem is people tend to ignore basic things like using pks or indexes while making them.

Is there any way to log in to active directory from a mac without joining the AD domain?

I am looking for a way to log in to active directory without having the Mac join the AD domain. Basically i have not been able to understand all the ramifications of joining the AD domain. From what I have read in various documentations on the apple site and some of the AD plug in sites, it seems that if the mac joins the domain, all kinds of group policies get 'transfered' to the mac experience. How exactly does that affect the privileges of the local mac user on their machine? do they need to change their mac password? what happens to their existing home directories? what happens when they have their laptops at home?
TIA

The reason i am hesitant about binding the macs is that i'm not sure what are all the effects of that. will they have to change their mac passwords / usernames? more than likely the auto login will have to go. If there are multiple accounts on the mac (ex one admin account and other regular and admin accounts) how does binding affect them? how will it work when the mac is not in the office? if they have admin rights on the mac but not on the windows AD, how will that affect them? Do you know of a source i could go to to find answers for questions like these?
Unfortunately, the source for answers should be your IT department. I can tell you how my machine works. I have a personal machine with no restrictions and a work machine bound to an Active Directory domain. Even my work machine has few restrictions compared to normal. I have a privileged account I can use if necessary. Also, I'm pretty much a goody-two-shoes so I don't try to circumvent restrictions.
Basically, the Mac uses a system called Open Directory to manage user accounts. Every Mac comes with its own miniature Open Directory server. If you have a network with MacOS X Server, you can use the server's Open Directory. You can also use Microsoft's Active Directory to perform all the same tasks. The user's logins and passwords would be whatever is on Active Directory. They can change their password on the Mac and it will change the Active Directory password. Active Directory can enforce passwords expirations too.
I am not an Active Directory administrator, so I can't give you specifics. Pretty much everything you have mentioned can be controlled via Active Directory. That is what it is for. It does require active participation of your IT staff. If you don't have that, then I don't see it working out well. It sounds like a paradox. IT wants to control users, but doesn't want to deal with it. You can't have it both ways. Maybe let it be known among the Mac users that visiting those restricted sites could cause IT to get rid of Mac altogether. That does sound like a probable outcome.

Drawing line from thin to thick

I need to draw a line where some segments of the line is thicker than the rest.
I can draw the lines, but I need some kind of smooth transition from thin line to thick and the other way around. I'm using generalpath and stroke to draw the lines.
What is the best (easiest) way to do this?

Check out following code if it works for you. I've used b-spline approach to generate the shape of the path. You just need to specify control points and width at them.

Creating new projects from old ones without deleting the wrong audio files!

We did a piano & vocal recording session recently and recorded about a dozen songs. Voice audio files and midi (pianoteq) for piano. At the moment these are organised into three projects according to genre - classical, showtunes and jazz standards. I now want to get each song into its own separate project but while I need to avoid duplicating too many audio files, I'm also scared to death of deleting anything!
Can someone please walk me through how I do this? I THOUGHT I knew and then a dialogue box (thankfully!!) flashed up saying something like, "Are you sure you want to delete these files they are shared by other projects?"
I basically want to "save as" one of the large projects, rename it according to the song title and then delete the other songs from the Arrange. I thought I could then "select unused" in the Audio Bin and it would be cool because the original audio would be in the old (renamed) project . . . but I seem to have that wrong? Or I've missed a step?
Hopefully someone can shed some light!

Open the song. Cut the tracks at the appropriate places. Name the newly created regions with the correct song names. Select all the regions and then the command that turns the regions into new individual audio files. After the files are written, go into the audio bin and select unused. Delete unused. Save as (without resources) "Master Song". Then I'd delete all but the first pair of tracks from the arrangement. In the audio bin select unused again then delete. Logic will dump the unused parts out of the audio bin without deleting them from the drive. save as "First song" Re-open the master song and do this again with the second set of tracks.......

Launching another Swing application from existing one using Runtime.exec()

Hi,
I have two separate Swing applications, say A and B. I need to launch B from A using Runtime.exec() - essentially I am launching another VM instance from one VM. I am encountering strange problems - B's main window comes up, but GUI doesn't update; sometimes B comes up and GUI updates, but huge memory leaks happen. All the problems with B go away once A is shut down. It almost looks like both the instances of VM are sharing (or competing for) the event thread. Any comments will be of great help. Thanks.
note: There is no problem launching B if A is a console java application (i.e. no Swing GUI).

Do you have to have the second application running in a seperate VM (process)? If not completely neccesary, then you can just invoke the static main() of the second class. If the type of the second class isn't known untill run-time, you can use Reflection to invoke the method.

How to install from existing linux without root privilege?

We have a ubuntu server for develop in our company and I have a account. I am more familiar with archlinux. However, I can't just tell the system administrator to replace ubuntu with arch, since that would break everything. And I do not have root privilege. So I am wondering would it possible to install archlinux in the home directory, and use it like a virtual machine?

Pacman needs root privileges (sudo) to work.
So if sudo works for you, then you have root privileges.
Maybe fakeroot or fakechroot?
Trilby wrote:
Ubuntu + pacman != arch.
If you are able/allowed to reboot the machine, you certainly can install arch on a flash drive and have your portable system that you would run on their hardware.
I am asking something different. I want to run arch on another linux.

What, specifically, would you like to install to your home directory that you can run with plain user permissions without causing impact to other users. I am confused as to what you think you want to do..
Something like, install software (including pacman) to home directory via pacman. Start a server by rc.d (I think in this case, sys-V is better than systemd).
For example, I could run this command in ubuntu without root permission, and that ubuntu server didn't install mysql.
$ pacman -S mysql
$ rc.d start mysqld
$ #Or "systemstl start mysqld.service"

HT201328 Is there any way to confirm that Iphone4 is unlocked from existing carrier without swapping the SIM card from new carrier ?

I have followed AT&T instructions to unlock the phone and don't have any micro-SIM handy to try it out.

Did you receive the message that says "Congratulations! Your phone is now unlocked etc. etc." after completing the restore of your phone?
If so; Then the phone is completely unlocked.
If not; Then the unlock has not completed correctly, in which case you should attempt restoring again, and then failing that, contact ATT to make sure the unlock has fully processed from their end

Draw non-joined lines from endpoint of existing lines

I asked on the general AI forum how to draw lines from existing line endpoints without the two being joined, and I got the answer that you can't. So I think this calls for a feature request: give the user the possibility to draw a line at the endpoint of a pre-existing line without joining the two. Up till now the current functionality has two drawbacks for me:
1. It makes creating the following pulse diagram a PITA:
When I draw a line starting from the arrowhead the arrowhead moves to the new endpoint. Here I had to draw the new line elsewhere on my page and drag it over the arrow.
2. If you draw a line to the end of an existing line in a group it gets automatically joined to it, and thus becomes part of that group, even when you're not working in isolation mode. Again I have to draw my line at another place on the page and drag it to the grouped object afterwards.
So, feature request: allow lines sharing a common end- and start point without being joined.

This is not the ability of usual flex classes. You should explore on how the 3D coordinates system of Flex works, and learn some classes usability, such as Matrix3D, for example.

Begginner: Drawing lines in xcode

I have some experience in other languages (flash actionscript and visual basic), and love to fizzle around with quartz composer. I normally use programming as a way to prototype and test some ideas and pet projects, and as another mean to express myself, but I am feeling that I will have to learn new things in order to grow. I never used xcode, though..
I want to be able to open xcode and draw a small program that draw lines from A to B.
I don't care at this point where A and B are, i just plan to draw the lines. If possible in such a way that opens me possibilities of rendering those lines with multiple filters as one do using quartz composer.
Where do I start?
thanks.

You have to subclass NSView and implement drawRect: with something like
[NSBezierPath strokeLineFromPoint:p1 toPoint:p2]

Copy Sales Order from existing

Hi Experts,
Can i copy a sales order from existing ones? I am not referring to create by reference. Just create the new sales order which has the same information as the existing.
Thanks

I know you are not referring to 'Create by ref' but it seems thats the option you are looking.
If you hit 'Create with ref' on VA01 and goto 'Order' tab and specify the sales order number which you want to copy it will copy all the values from that order and create a new one for you.
And of course sales order number will be different.

Create a new schema from existing schema

Hi, I'm wondering whether there is a way of create a schema from
existing one? Could it done through SQL statement or have to go
through some sort of tools? Please drop me a few words if you
know the answer. Thanks.

Hi,
U can do that in a few steps.
First create the User.
Then Go to the Source User and grant him create any table privs.
Then write a Sql Stmt to generate the necessary scripts and run it.
The other way would be to grantr the newuser select on all the tables and then run that script from his account.

Without the Sync Key, even if you could connect and download your data from the Sync server it would be useless without your Sync Key. The Sync Key is used to encrypt & decrypt the data going to & coming from the Sync server.
