  • (pic included) Quick question about making a rendered logo

    Here is what my artboard looks like. What I'm trying to do is just get the black shapes as one solid logo without the white showing. For example, if I were to place this in another Illustrator project, it would still have the white rectangles with full transperency. I tried a tut online, but when I place the AI file into another project, the WHOLE image is invisible.
    If I were to open this AI file in Photoshop, I could use the Magic Wand to delete the white parts and leave just the black shape. I want to be able to resize the black shape and use it on banners, avatars, ect. Any help out there please?!
    I ALSO HAVE TEAM VIEWER!
    Background notes:
    I am using this for my gaming website and I would like to be able to use this for my logo. (Crossfire)
    Thanks all!

    C2,
    I don't see unite under pathfinder.
    In earlier versions Unite was called Add to shape area. You may need to press Alt/Option to get a simple path (again depending on versions).
    Apart from that, there is an Effect>Pathfinder which you should avoid and use the View>Pathfinder palette (bundled with the Transform palette).

  • A quick question about WebDynpro SLD and R/3 with concurrent users

    Hello ,
    I have a very quick question about Webdynpros and SLD connecting to an R/3 system, when you configure a webdynpro to connect to an R/3 system using SLD, you configure a user name and password from the R/3  for the SLD to use. What I would like to know is when I have concurrent users of my webdynpro, how can I know what one user did in R/3 and what another user did? Is there a way for the users of the web dynpro to use their R/3 credentials so SLD can access the R/3? Like dynamically configuring the SLD for each user?
    - I would like to avoid leaving their their passwords open in the code ( configuring two variable to get the users username and password and use these variables as JCO username and password )
    Thanks Ubergeeks,
    Guy

    Hi Guy
    You will have to use Single Sign On to achieve this. In the destination you have defined to connect to R/3 , there is an option to 'useSSO' instead of userid and password. This will ensure that calls to R/3 will be with the userid that has logged into WAS. You wont need to pass any passwords because  a login ticket is generated from WAS and passed on to R/3. The userid is derived from this ticket.
    For this to happen you will have to maintain a trust relation ship between R/3 and your WAS ,there is detailed documentation of this in help files. Configuration is very straight forward and is easy to perform

  • Question about source system copy for BW

    Dear all,
    I have a quick question about copying a source system for BW.
    We have two clients in the source ERP:
    100 Customizing
    200 Testing
    Our BW is only linked to client 200, so when we now delete client 200 and make a copy from 100 to 200, are we then still able to restore the source system connection so that our extraction will work, or will it fail, as in client 100 I have no BW related (except the cross-client-objects like datasource) information, that can be used for a possible restore of this connection.
    What is the procedure in this case?
    Thanks,
    Andreas

    Unfortunately, you will lose your source connection and need to create a new one in R/3.  You can use the same source system name in BW, but check the source system connection after the copy (SM59).  Also, I would "Restore" the source system (in BW, right-click on Source system in RSA1, and click "Restore") to insure the datasources get replicated from R/3 to BW.
    Depending on how much you want your BW and R/3 systems to be in synch, you will need to rebuild all your data providers (cubes/ODS's) from your R/3 system.  This means deleting all the data and running the initializations from scratch.  At the very least, you will need to rebuild the delta queues.
    Curious, if 100 is just for customizing, is there any data in it?  Are you just creating a new blank client 200?

  • QUICK QUESTION ABOUT PORTS

    Hi, I have a quick question about port forwarding/mapping. My question, lets say I am running MSN messenger, who's ports are 6880-6900. But lets say I am running a torrent application or something else that requires those ports. If both applications were running at the same time, would this cause interference with them on the same ports or now. Thanks
    Nathan

    Normally, only one application can listen to a specific port number at a time. If MSN is grabbing those 21 ports then your torrent app won't be able to run.
    However, most apps don't work that way - even if they use multiple ports, they don't use them all at the same time, so MSN might use 6880 when it starts up, leaving the others open for other applications to use if needed.
    Only experimentation will answer that one.

  • Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

     

    Make sure that your bean is implementing the serializable interface and that
    you are accessing the bean from the session with the same name.

  • Question about operating system

    Hello.
    I just got lenovo T400. I have question about operating system. I choose OS (Windows XP Professional preinstalled through downgrade rights in Genuine Windows 7 Professional). When I get the laptop, Windows XP is preinstalled but I don’t know how to upgrade to Window 7. Please, tell me the way to upgrade.
    Have a nice day

    you'd need the disks, and would need to do a fresh install, i.e. you can't just upgrade it. everything will be gone

  • Quick Question about Cisco 3560 and the Web Device Manager

    Alright, I have a quick question that I am curious about but I haven't found any information
    about it.
    When I log into my Cisco 3560 using the web portal to get to the Device Manager. Below the
    diagram of the switch, then under the Dashboard there is section called Switch
    Health, Port Utilization.
    Under the Switch Health there is Bandwidth Used, Packet Error. Those two options just sit
    at zero and do not move. The Port tilization graph is also sitting at zero.
    Is there a way to make them functional?

    Anyone notice performance increase or decrease of their HD when using the nVidia IDE SW drivers?  particularly with a 74GB Raptor?  I've also heard of burner issues when installing the IDE SW but have not used my burner yet.

  • Making system calls in java

    I want to join some split files into one. In command prompt I use COPY /B file.1+file.2 file to join the files. How can i do the same in my java application. Please show the code which I suppose will use getRuntime. Thanks in advance.

    Well if there is a problem with system calls then can
    you tell me if there is a class in java for
    concetanating files. Not directly.
    At present I am joing the files
    by reading each byte from the files and writing them
    to another file which takes hell lot of time. You should read the files in large chunks. Much much faster.
    Thanks
    in advance again. Also if you say about sequential
    file class then please expalin a bit bcs I couldn't
    implement it.Post the code you are having trouble with explaining what it should do and what it actually does.

  • Quick question about sim transfer

    Hi all,
    I have a quick question and hopefully one of you guys would be able to help me. My friend purchased his 3g iphone today and hes giving me his old iphone. I currently have a blackjack and I wanted to take the sims card from the blackjack and put into the original iphone. Will the iphone work with my sims card? It is an older sims card, says 64k on it. If not, would I have to bring it into at&t and get it activated w/a different sims card? Hopefully all this isnt confusing. Thanks for any help. Cheers!

    You're welcome.
    I guess that also means I would have to upgrade to the 20 dollar data plan without the text messages as well?
    The unlimited data plan for the first generation iPhone still costs $20/mo and includes 200 SMS. The only thing you need to get from an at&t store is a new SIM card. Take the iPhone with you telling them what you plan on doing and they should give you a new SIM card at no cost.
    You will activate this iPhone with iTunes on your computer. If you are an existing subscriber, your calling plan will transfer to the iPhone, and any existing data plan you are using with your current phone will be cancelled. If you are an existing subscriber, your only selection will be the $20/mo unlimited data plan which includes 200 SMS, and you can select 1,500 SMS for an additional $10/mo or have unlimited SMS for an additional $20/mo.

  • Adding menu items and making system calls in AfterEffects (AE,CS3)

    We are looking to do the following things via javascript in AfterEffects CS3. It does seem straight-forward, but am unable to find a good reference or example.
    * Add at startup a menu item under "File" (or similar main menu) and have it call a script function when clicked.
    * Have a script make an external system call (to launch an external application/executable with a few parameters)
    Any insights on how to achieve this?
    Many thanks!

    I wanted to see if there was any update on this, I'm writing a series of tools and would love to create a custom menu for quick and easy access.
    If it turns out there isn't an "easy" way to do this (env variables, special directory locations, javascripts) would anyone know if access to the menubar is possible from the Plugin API?
    I'm fairly new to After Effects, just getting up-to-speed on the environment now... seeing if I can duplicate the functionality of some old Nuke scripts in AE.
    thanks,

  • IMovie - quick questions about video files when importing and optimizing

    Hi, have some quick questions. I think they are simple.
    1. When I import a video (from say iPhoto), where does it get "Move" or "Copy" to?
    2. Why would I want to do "Copy" instead of "Move", because isn't it then taking up more space?
    3. I'm wondering if after I optimize a video, I can stash away the original (non-optimized video that I either "Move"d or "Copy"d earlier) into an external hd.
    4. By the way, what is the new file name of the optimized video?
    Though things are working fine in iMovie and iPhoto, I'm trying to manage hard disk space, and hope answers to these questions will help.
    Do you guys have a guideline on how to manage hard disk space when it comes to iphoto and imovie?
    Thanks.

    As has been suggested you can encourage people to download QuickTime player by doing something like this...
    http://www.mirroroftheuniverse.com/Songs.html
    You can also present your songs like this...
    http://roddymckay.com/Satellite/JukeBox.html
    This is a SnoCap jukebox and you need an account to use it but you'll get the link to ESnips on the above page.
    A 3 minute song has a file size of about 30 Mb in AIFF format. Converting it to MP3 reduces it to about 3.5 Mb and M4A to about 5.5 Mb.
    iTunes will do these conversions for you and M4A is far superior to MP3 as far as sound quality is concerned.

  • About making a call

    My BB 8900 could not make a call! All are working except on making a call.

    Hi and Welcome to the Forums!
    Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
    Best!

  • Quick Questions about the New T530

    With the T530 finally showing up online for those of us in the U.S., I have thrown it into the pool of models I am considering and comparing it to the T520, but it is getting very hard to find information about it. Here are my top questions about it that I can not find answer to.
    #1: Can the backlight on the keyboard (if you choose to get one with it) be toggled? If so, would it be through bios, a key combo, or software?
    #2: Will accessories for the T520 be compatible with the T530? Including the 9-cell and the slice?
    #3: Because this is a new item, and there might be high demand, is there a possibility of shipments bottlenecking? I.E.: if I buy one right now, will my order get postponed multiple times and take months?
    Sorry if these answers have already been answered elsewhere, but I really did try (used Google and the forum search) to find the answers before posting. Plus, I'm sure there are a few people like me trying to decide between the T520 and Ivy-equipped T530, so maybe this thread will help them too.

    joshua144,
    This is a bit outside my area of expertise, but I don't think the slice battery from T420/T520/W520 generation will work on the new systems like T430/T530/W530 which require battery authentication.
    Check the tabook  http://www.lenovo.com/psref/pdf/tabook.pdf  to know which battery options are supported on which systems.  And note that the slice battery option for T520 is different than the slice battery option for T530.
    Just because the 28++ battery (from your link) is backwards-compatible with the older systems, does not mean the older batteries like 27++ are forward-compatible with the new systems.
    As for your other question about FN and CTRL, the FN button is still on the outside of the keyboard just like ThinkPad has always been.  And there is still the BIOS option to swap CTRL and FN.

  • Two quick questions about Library after moving beginning on a new computer

    Hi there,
    I just moved from Windows to Mac, meaning I had to move my iTunes library from the old PC to my new MBA.
    Just a couple of quick questions.
    1. When I started iTunes on my new Mac, in the preferences I directed the media folder to the folder with all my itunes music/podcasts etc, and then I imported the Library XML file.  Is this incorrect? Should I have imported a different file? Should I have used the itl file instead? 
    If so, should I delete the library and start again?  (if this is the case, please suggest the best way of doing this without affecting my media)
    - a kind of sub-question to this one:  some of the media files arent showing up in the iTunes library, but they are in the media folder on the ext HDD.  Is there a way I can find out which ones havent been recognized by iTunes?  Whats the best way of getting them in to my library?
    2. Pretty much half of my podcasts have not been loaded in the new iTunes.  The ones that havent were ones that I subscribed to on my iPhone, whereas the ones that show up in iTunes were ones I downloaded from iTunes.  When I connect my iPhone and sync it with iTunes, will those podcasts show up in iTunes?  Or is there a risk that they will be deleted from my iPhone?
    Cheers,

    The .xml is lacking some information such as ratings, date added, and play count.  Using the .itl includes this information but cannot be imported using the method you did.
    A complete library is everything in the iTunes folder.  By using the method you did you left the artwork behind in the artwork folder on the other machine.
    Selecting the media folder in preferences does not get iTunes to recognize the media.  All it does is tell iTunes to start storing new media in that location.
    Using the method I outlined nothing will be missed (with the exception of WMA) because you aren't rebuilding your library, you are using the one that already exists.
    You don't have to re-copy everything as long as you get the stuff you missed and re-assemble it all as it was before except not on the Mac.
