Newbie problem with new objects and tools.

in chapter 4 of the after effects essential training series from Lynda.com in the section about controlling animation with the pick whip. when he applies the null object the red bar immediately populates (correct usage?) the timeline to the right. when i apply the null object it's hidden to the left, under all the layer info, and i need to drag it out into view.
ive found that whenever i have a problem, e.g., im using a tool and nothing is happening, it always comes down to this same thing: the layer is not with everything else and i need to drag it out into view.
not only am i new to mac, but im only marginally literate and a total newb to anything more advanced than iphoto, any advice would be appreciated.

I'm not understanding what you are asking.
If you have a layer in the timeline, a null, and the parenting column is visible you simply click on the pickwhip next to the layer and drag it to the name of the null layer. The Parenting box now says that Layer 1 is connected to Null 1.
Now, when you move the null, the layer will move.
i understand what they do and how to set them up.
my question is more specific, but also applies more generally to other tools and layers. when Ian creates his null layer in the video (as well as other layers ive seen him create) the red bar that represents his null layer immediately appears in the timeline with the begining of the red bar at the left end of the work area. it is fully visible. when i create one the file shows up in the list of layers on the panel to the left of the time line, but it is not visible in the comp window and the red bar is hidden to the left side of the visible timeline to where you have to click its right end and drag it out from behind the panel on the left.
this has happened with other layers ive created using other tools and before i figured out what to look for it was very frustrating. now, whenever i can't find something, or a tool that im using isnt doing anyhting (besides creating more and more layers) ive learned to look and see if theyre just hidden. it seems like it's probably a setting. but clearly, something is different: he creates a null layer and it appears in the timeline, and mine appear slid to the left.

  • Problem with Retrieving objects and using info...

    Ok heres my problem.
    I have implemented a Queue using a linkedlist in java. Ok then i created a new object(in its own class - called Data) with two values, amount and price. I want the queue to store these two values in one Node. So i pass the values to it like this:
    Data A = new Data();
    A.price = Intger.parseInt(jTextField.getText());
    A.amount = Integer.ParseInt(jTextField.getText());
    Now I pass the Queue like this
    Queue B = new Queue ();
    B.enqueue(A);
    Which seems to work fine, the problem is that I need to work with the numbers in the Queue, update them, put them back and retrieve them.
    So I create a new Data object and try to dequeue like this:
    Data C = new Data();
    C = B.dequeue(); //So i can work with the two values
    but this doest work. It gives me the error that it needs an object.
    Am I doing it right?
    Anyone got any better ideas on how to do this? - Passing and retrieving two values to one Node.
    Plz help, im a newbie in Java, and cant find any tutorials on the internet.

    why don't you use vector.
    Vector queue = new Vector();
    Data a = new Data();
    a.price = Intger.parseInt(jTextField.getText());
    a.amount = Integer.ParseInt(jTextField.getText());
    queue.addElement(a);
    Data c = new Data();
    c.price = Intger.parseInt(jTextField.getText());
    c.amount = Integer.ParseInt(jTextField.getText());
    queue.addElement(c);

  • Problems with new iMac and Adobe Creative Suite 2

    Just wondering if anyone can help me out. I am a Graphic Design student and just bought Adobe Creative Suite2. I installed it on my new iMac, and it wouldn't open InDesign or Photoshop although I had no problems with Acrobat and Illustrator. A pop-up window stated that the program "unexpectedly quit". I have uninstalled and reinstalled three times and was on hold with Adobe Tech Support for three hours until I finally gave up. If anyone knows what's going on I would appreciate it!

    I dragged the installer from the install disk to my desktop and was more successful in installing problem CS2 apps. Make sure to update everything as well. Some times it takes a restart to get the finickiness out of PS.

    Hello,
    We are encountering a problem with the application "Business Objects FINANCE", and we would need your help quickly.
    In the application , itu2019s impossible to print Consolidated Subsidiaries nor the Securities Held. If we try so, the application freezes and we can't do anything but killing the application via the task manager.
    Though, other states can be printed without problem.
    We tried on several different PCs, and the problem occured equally on each one.
    The version installed is 10.5, and we can do any tests that you think would be useful to diagnose problem.
    Our society is AUBAY SA, and our credential to enter in your support website are : S0005386617
    In attachment youu2019ll find a screenshot of the event viewer from the server where the application is install.
    Thanks in advance for your answer,
    best regards.

    check the export parameters of the event triggering workflow.
    If there is a problem, try instantiating the object in your wf based on the key.
    Also check if the wf is able to import the data.

  • Problem with New HDD and installation of Qosmio Player

    Hi All,
    Hope someone can help, I have had my Qosmio for 2 1/2 years now and recently had a problem with the hard disk. I decided to replace the hard disk as this was the quickest solution. The problem I have now is that I cannot receive TV on media center. I was trying to install qosmio player on the HDD to see if it made any difference but when I run the recovery disk supplied the software tells me that there is not enough disk space!!. The laptop came with a 60G hard disk and the new HDD made by the same manufacturer is a 150GB, can anyone help me out with this one would be appreciated.
    Thanks
    ED.

    Qosimo F10.
    Sorry my previous entry was garbled. I upgraded the HDD to 120, could not get the Qosimo player to reload, same error, No space on HDD.
    I then upgraded to Vista and downloaded the new Vista Qosimo drivers, created the ISO image and booted from it. Still did not work.

  • Is there a problem with new Firefox and Gmail?

    I cannot get Gmail to work consistently with new Firefox. sometimes it loads, sometimes it lets me enter my password details and then crashes; sometimes I can view my inboxes up until I select a message and then it crashes... I've submitted several crash reports already but not heard anything back as yet.

    Thanks for replying. Only trouble is that the machines I'm having problems with already run the most up to date versions. In fact, by pure fluke, my wife's laptop which has automatic updates switched off is running FF 8.0.1 and this is the only way I can consistently access Gmail without crashing.
    It runs XP if this information is useful.

  • Having problems with new ipad and charging?? Help me please

    I have the new ipad with retina display and it had that new smaller charger as you probably already know, well I've only had this ipad for about three months and I've already gone through two chargers for the same problem which is When I plug it in it does not charge unless I unplug it and plug it in about 40 times and then it starts to charge! Do you think it may have something to do with the ipad itself or am I just getting faulty chargers? It's not that cheap to keep re-buying these chargers ):

    ... am I just getting faulty chargers? It's not that cheap to keep re-buying these chargers ):
    Since your iPad is quite new, why are you "re-buying" chargers?  Are you not using the charger that came in the box -- the original Apple charger?  If you were doing that, and did not mishandle the charger (e.g., tug on the cord to pull the charger out of the wall socket), Apple would take care of the charger under its warranty.
    So I suspect you're either mishandling the charger (not likely), or using some third party charger (more likely).
    If it's the original Apple charger, and you're not mishandling it, contact Apple for assistance.

  • Newbie: Problem with jdbc-odbc and MS SQL server 2005

    I'm on win vistax64 with SQLSERVER 2005 and I have set up the odbc source as system dsn using the SQL Native Client driver with SQL authentication and the connectivity test in the end succeeds.
    I'm trying to make a simple web app that will connect to the database and perform simple querries. It's a school assignment.
    I'm using the jdbc-odbc bridge because it's the simplest way to do it and it's what we were shown in class.
    I get the following irritating error:
    "Cannot establish a connection to jdbc:odb:sstmdb using sun.jdbc.odbc.JdbcOdbcDriver ([Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifies)".
    I'm working with netbeans 5.5.1 and this error is what I get when in the runtime tab I try to connect with the jdbc-odbc. I get a similar error in the logs when I try to run the app on the j2ee server.
    This is the java class that establishes the connection.
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.SQLException;
    public class Connector {
        private static final String dbUrl="jdbc:odbc:sstmdb";
        private static final String user="kimon";
        private static final String password="jackohara";
        public static Connection getConnection(){
            Connection conn = null;
            try {
                Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                conn = DriverManager.getConnection(dbUrl,user,password);
            } catch (SQLException e) {
                e.printStackTrace(); 
            } catch (ClassNotFoundException e) {
                e.printStackTrace(); 
            return conn;
    }It has worked perfectly on my school PC with winXP and MSDE2000.
    What am I missing?

    Ok, help came from an other way where I was inquiring about a different problem:
    Connectivity works fine by using User DSN instead of System DSN for the ODBC source.

  • Problems with new iMac and Maverick: ITunes and Time Machine

    Just upgraded from an old to new iMac, migrated my data from my old machine and installed Maverick. Couple of major problems.
    1. My iTunes library won't open. I've been into the library folders but can't work out how to get the old library to load. Decided to try a sync back from my iPhone but while the phone tells me that it has synced with my Mac, the music hasn't moved across.
    2. Time Machine doesn't work. On my old machine I was using an external Omega hard drive but when I plug it into the new Mac it isn't even showing up on the desktop. Clearly there's a connection of some sort as the disc is powering from the Mac. Prior to upgrade, I was getting messages that Time Machine couldn't be updated but I put that down to my failing elderly Mac, which kept crashing, freezing and needed replacing. Perhaps the external drive was dying too.
    Any suggestions welcome.
    Thanks,

    I dragged the installer from the install disk to my desktop and was more successful in installing problem CS2 apps. Make sure to update everything as well. Some times it takes a restart to get the finickiness out of PS.

  • Problems with new ISP, and base station now disappeared

    I had been happily using AX for my wireless connection for a year and a half with no problems (well, apart from the alleged wireless printer issue...grrr). Now I've moved and have had to change my broadband/ISP provider. I now have an ADSL router (BT voyager 210). I can connect by ethernet cable but no joy with my AX, despite a solid green light, strong signal and recognised network. I spent two hours on the phone to a helpdesk in India today and managed to reconfigure some of my base station settings, but now my base station has disappeared from the network list completely and the AX just flashes amber. I've tried resetting it with the old paperclip routine but nothing. I'm going nuts turning it on and off and trying to figure it out... any ideas?

    Hi melsteel,
    reset to factory settings using the instructions from here:
    http://docs.info.apple.com/article.html?artnum=108044
    After you've done that, choose your reconfigured AEBS from the dropdown menu, run setup assistant, then go into Airport Admin in the Utilities menu and set up some security
    Create new network names, get rid of the old stuff, just start all over, you'll be glad you did

  • Problem with serialized objects and JWS

    My JWS launched application fails when loading a serialized object that has been instatiated from a class not contained in the signed jar-file. Does anyone know why this happens and if there is some workaround for the problem?

    Where is the class contained then?
