A better way to zoom?

hi all--
I'd like to zoom in on some detail in my animation/presentation on the stage-- One way I know to do this is by creating a container mc that holds all the contents, then scale that mc up to simulate a zoom-- but then I lose my layers on the individual assets. Is there a smarter way to do this?
thanks

thanks Ned,
I meant to say that if I have 10 objects on stage, each on a separate layer,
then create a container mc to hold them all-- the new mc (and all content)
gets placed on a single layer. I guess I was a bit confused earlier,
thinking that I would really need to retain the original layers-- I
suppose it's not really necessary-- but it makes editing more of a chore....

Thanks for posting the CREATE TABLE and INSERT statments. Remember why you go to all that trouble: so the people whop want to help you can re-create the problem and test their ideas. When you post statemets that don't work, it's just a waste of time.
None of the INSERT statements for tab2 work. Tab2 has 6 columns, but the INSERT statements only have 5 values.
Please test your code before you post it.
I need to get all rows from tab1 that does not match tab2 WHat does "match" mean in this case? Does it mean that tab1.ref_cd = tab2.ref_cd?
and any row from tab1 that matches ref_cd in tab2 but key is different.
Existing Query
select
ref_cd,
key
from
select
ref_cd,
key
from
tab1, tab2
where
tab1.ref_cd = tab2.ref_cd and
tab1.key    <> tab2.key
union
select
ref_cd,
key
from
tab1
where
not exists
select 1
from
tab2
where
tab2.ref_cd = tab1.ref_cd
Does that really work? In the first branch of the UNION, you're referencing a column called key, but both tables involved have columns called key. I would expect that to cause an error.
Please test your code before you post it.
Right before UNION, did you mean
tab1.key    != tab2.key? As you may have noticed, this site doesn't like to display the <> inequality operator. Always use the other (equivalent) inequality operator, !=, when posting here.
I am sure there will be an alternate way to write this query in better way. Appreciate if any of you gurus suggest alternative solution.Avoid UNION; it can be very inefficient.
Maybe you want something like this:
SELECT       tab1.ref_cd
,       tab1.key
FROM           tab1
LEFT OUTER JOIN tab2 ON tab2.ref_cd     = tab1.ref_cd
WHERE       tab2.ref_cd IS NULL
OR       tab2.key     != tab1.key
;

Can some one tell me a better way...

Hi All..
I work on a web application. I create user ids for people logging into my application. here I have a small problem.. This is what I am currently doing...
When I create a new user, I assign a new user id to the user and store all hi info.
All our user ids are stored in User_ID table and user info in User_Info table.
First I get the max user id from the User_Id table.
int iuserid = select max(User_ID) from User_ID;
Then I add ' 1 ' to this and assign it to new user.
iuserid = iuserid+1;
insert into User_id values(iuserid, <ssn> );
Then I store all user info in User_info table..
insert into User_info(iuserid, <first_name>, <last_name>,...);
Both these SQLs are executed as a transaction.
The problem that I have...
It works fine in a normal environment and in my testing.
But when the load inceases, before I insert into the User_info, another user tries to get the max User_id from User_ID table, then it conflicts..
I have seen occurences of User_Info storing the info of a different user against the User_id when many people are accessing the app at the same time.
Can some one tell me a better way to handle this scenario..
Appreciate all you help..
TIA..
CK

Hi,
assuming that the requirement for user_id is only for uniqueness (primary key requirement) not continuosly.
perhaps can try this,
1) create a table to keep the max id for each table's key.
e.g.
create table key_id_lookup
key_name char(n),
current_value number(m)
where n & m is the size of the field
2) for each creation of entry in the user_id table, lookup the value in the key_id_table and increment it after retrieval.
e.g. current_id = select current_value from key_id_lookup where key_name = 'user_id_key';
current_id+=1;
update key_id_lookup set current_value = current_id where key_name = 'user_id_key';
something similar to use of sequence if your database support it.
3) continue with the creation of record in other tables. now obtain the time stamp of creation and append with the current_id obtained. e.g. timestamp = 132456872; size of m is 5, user_id = 132456872 x 100000 + current_id;
this should give you a unique key at creation time.
There should be other better ways of resolving this(like locking the table for the update operation but affect performance, etc), depending on the feature supported by the database in use.
Hope this can help as last resort if other options not available.

A better way to execute a series of external commands?

Hi,
Consider the code snippet...
Process proc1 = rt.exec("Some external command");
Vector vecOutput = outputGobbler.getOutput() ;
String[] strAlterCmds = new String[vecOutput.size()];
for ( int k = 0 ; k < vecOutput.size() ; k++ )
strAlterCmds[k] = new String();
strAlterCmds[k] = "cmd.exe /c blah.... " +(String) vecOutput.elementAt( k )+ " ;
Process proc2 = rt.exec(strAlterCmds[k], null);
StreamGobbler errorG = new
StreamGobbler( proc2.getErrorStream(), "Error") ;
StreamGobbler outputG = new
StreamGobbler( proc2.getInputStream(), "Output") ;
errorG.start() ;
outputG.start() ;
int exitVal1 = proc2.waitFor();
The second part of the execution is taking AGES and I am not sure forking a new process for runtime execution is the best alternative here.
I would be glad if someone can point me to a smarter solution.
In short: I intend to execute a series of commands using RTE depending on the values I get in the loop.
Thanks.

Jared,
Thank you for responding to my posted message. Rendezvous is a new concept to me, maybe
it's the solution to my problem. I have been trying to read the on line manual and
example VIs from National Instruments website. I still have a hard time to understand
the concept.
One of the example I saw is using rendezvous to run some sub VIs. But in my case, I have
only one VI that is a while loop. Inside the while loop, there are a few tasks running
simultaneously. I don't know whether it will serve my purpose.

A better way to activate an LOV

I want to allow users to activate the LOVs and run queries from them without having to press the enter query button, then move their cursor to the appropriate text box, then press Ctrl+L, then press the execute query button. Is there some way to fire an LOV from a button press or some simpler way than I have right now?

Thats really a good way.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Steven Lietuvnikas ([email protected]):

A better way to poll

When my Start button is clicked it changes a member variable from false to true.
Here is a simplified version of my code:
public class gdvdhomevideo
   private boolean blnBegin;
   public static void main(String[] args)
      while(blnBegin == false){}
      //perform operations
   public void actionPerformed(ActionEvent e)
      String command = e.getActionCommand();
      if(command.equals("Start"))
         blnBegin = true;
}So when the user clicks start it exits the while loop and the program starts performing other functions. The problem is that this approach is 100% CPU intensive and I know that there must be a better way?

1) Code executed in the main() is NOT running on the event thread. Don't do any GUI code from the main thread... You know, stuff like showing windows, attaching event listeners etc.. You need to wrap all that stuff in a Runnable and pass that Runnable to SwingUtilities.invokeLater().
2) Assuming the stuff you're doing in the main() is actually thread safe and doesn't touch the GUI, you can simply startup a new Thread and put your code in there. (see below)
3) You class name is named badly. Please check out sun's java coding conventions. It is very nice to have coding conventions. Use them! ;-)
4) if you want to setup your program as a loop rather than simply relying on user actions to fire events, then I'd suggest you use a timer that notifies on the event thread every X where X is a non-zero polling interval. I think there's a class is called SwingTimer that does this sort of thing for you.
What you're attempting to do is non-trivial.. so.. ummm.. have fun..
public class gdvdhomevideo
   private boolean blnBegin;
   public static void main(String[] args) throws Exception
        SwingUtilities.invokeLater( new Runnable() {
              public void run() {
                   //setup stuff in here.
   public void actionPerformed(ActionEvent e)
      String command = e.getActionCommand();
      if(command.equals("Start"))
         new Thread(new Runnable() {
            public void run() {
                 //perform operations but don't touch the GUI.
          }.start();
}

A better way to run a 7 day report?

Using Crystal Reports 11
I am hoping there is a better way of running a seven day report that i have to run weekly
In the report i have it set when refreshing the document, the "Prompt for new parameter values" comes up and there is a date field for start and end
This is how i did it
I made a formula called "Date" this comes from the closed date of our accounts
I made a Parameter Field "Start Date" with the TYPE field is "Date"
I made a Parameter Field "End Date" with the TYPE field is "Date"
I made a Select Expert Using data from the "ClosedDate" in the first drop down I picked "Formula" and used this as the formula
{WH_ACCTCOMMON.CLOSEDATE} in {?Start Date} to {?End Date}
Two things
1. Is there a way to have "Prompt for new parameters values" as the default checked off box when clicking "Refresh"?
2. Is there a way to only enter a start date and the refresh would just run 7 days without entering a end date?

Hi,
Here's a suggestion for question 1:
When you preview the report for 1st time there is no prompt window that asks you to select whether you wish to 'Use current values' or 'Prompt for new values'.
If the Preview window is open and you hit refresh again, this is when you get the pop-up with the above options. If you close the Preview window and refresh again, you would not get a pop-up and it will show the Prompt window instead.
For question 1, you can follow Alun's sugestions.

A better way to do ChangeListeners?

I find myself having to implement multiple change listeners in a single class, and I was wondering if there was a way to do this that wouldn't trigger compilation problems. For example, let's say you have a LineChart, and you want the chart to listen for changes to the data, but also changes to the user's smoothing algorithm selection. You might try declaring your class like this:
public class MyGraph implements DataChangeListener, SmoothingChangeListener {....where you've declared DataChangeListener, and SmoothingChangeListener as
DataChangeListener extends ChangeListener<SomeDataStructure>{...}
SmoothingChangeListener extends ChangeListener<ISmoothable>{...}The compiler will tell you immediately that MyGraph can only implement one ChangeListener.
In real life, I have classes that have to listen for multiple types of events, and both for the sake of semantic clarity and for the sake of feasibility, they need to implement those change listeners. I've used event buses in certain cases, but they tend to obscure what the class is actually listening to.
Is there a better way of doing this?

Event handling code is, almost by definition, controller code. So it makes sense (to me at least) to have event handling code in the controller. You can put the code I showed previously
someDataSeries.dataProperty().addListener(new ChangeListener<...>() {
   public void changed(...) {
someChart.animatedProperty().addListener(new ChangeListener<Boolean>() {
   public void changed(...) {
});directly in your controller. (I suppose I thought "MyGraph" was your controller, though the name should have implied otherwise to me.)
However, if you really want to have the event handlers defined elsewhere, you can still do so, while using anonymous inner classes (or lambdas when we all upgrade next September):
public class MyGraph {
private final ChangeListener<SomeDataType> dataListener = new ChangeListener<SomeDataType>() {
    @Override
    public void changed(...) { ... }
private final ChangeListener<ISmoothable> smoothingListener = new ChangeListener<ISmoothable>() {
   @Override
   public void changed(...) { ... }
public ChangeListener<SomeDataType> dataListener() { return dataListener ; }
public ChangeListener<ISmoothable> smoothingListener() { return smoothingListener ; }
}and you can then do
dataSource.addListener(myGraph.dataListener());
smoothingProperty.addListener(myGraph.smoothingListener());But I recommend the approach I first suggested: I use this all the time.

A better way to Read Bytes until Done ?

My question involves reading an unknown number of bytes from the serial
port. One method is to just wait a defined amount of time to receive
the bytes and hope you caught all of them. Better: count them until
they are all received. I have attached an image which shows the method
I use to count bytes until all bytes are received. However, this method
is rather slow. It's taking me 500mS to read data that I can normally
read in 230mS. Is the shift register making this loop slow? Is there a
better way to read the bytes until all bytes are in?

Thanks for your reply Chilly.
Actually, you are correct on both accounts, the delay and the wire from
the output of Write, and in fact, I usually do those things. I was just
in a hurry to get an example posted and didn't have my real data.
To put my issue in broader prospective, I have attached an image that shows boh methods I've used to count bytes. One
shows the method I use to count bytes until all bytes are received. The
other is a "hard wired" timer method that I try to avoid, but at least
it is fast. Notice the text in red. Why would I be able to read the
byes so much faster in the "hard wired" version? It has to be either
the shift register, the AND, or the compare functions, and I still
can't beleive these things would be slower than the Express timer
function in the other method.
Methodology: The 235mS timer used in the "hard wired" method was
emperically derived. The 150 bytes are received 100% of the time when
235mS is allowed. 230mS yields about 90% of the bytes, the it goes down
exponentially. I found that the shift register method method trakes
~515mS avg by putting a tick count on both sides of the loop and
finding the resulting time. I also did that with the hard wired method
and found it to be dead on 235mS which at least proves the Express vi
works very well

A better way to initialize imported taskflows and BCs with current user

Hello.
I'm currently developing a composite application containing one main application and a number of subapplications (modules) packed in adflibs.
Main application has a side menu and a dynamic region, showing taskflows (on fragments) from adflibs.
Main application is configured with adf security and it has current login and queries his ID. I would like main application to tell modules current user ID rather than each module to find out current user on their own.
So there is currentUserID input parameter required in each imported taskflow. And my question is what is a better way to process this ID in the modules?
What I have previously done is:
I've created a custom BC classes layer, VOImpl and VORowImpl have getIdUser() method. This method reads currentUserID parameter from pageFlowScope where the taskflow is storing the parameter.
Top-level View Objects have :IdUser query parameter and corresponding bind variable. This bind variable has value="source.getIdUser()", calling the method from custom VO class.
This way works fine but here and there I read that it is a bad practice to access pageFlowScope from BCs.
I could agree with this in case someone could share a better way.
So what is a good practice?
Thanks.

Why don't you use adf security for this? Read Oracle ADF: Security for Everyone which give you an overview and sample on how to implement this.

A better way to manage Notes?

We are a small team in collaboration on a book-length manuscript.My editors are inserting hundred of Notes into the document that I must cycle through and resolve each one. But I find the Note icon soooo tiny. When I'm at full page I can barely see those little guys. Is there any way to make the Note indicators bigger or something? In general. I don't see this Notes tool as very robust compared to change tracking type features found in word processors.
I just want a better way to manage the Notes flow.

Then you can Expand/Collapse notes in Story Editor.

It's also useful to tile a Story Editor window and the corresponding document's window, to have both views of the content.

PLSQL does not go through Java to access the database. The actual access to the database is via the same mechanism for both, so in some sense, both perform about the same. However, PLSQL datatypes have the same representation as database datatypes so there is no conversion. Java datatypes have different representations than database datatypes so there is a conversion cost associated with moving data between Java and the database.
If your processing is simple and you are moving a lot of data, PLSQL is likely the better choice. If your processing is more complex and you are moving less data, Java is likely the better choice. There are other things such as portability you should consider, but the amount of data and complexity of the code are the first considerations.

A better way to make Automator mount a volume?

I made an Automator application, using the Record function, to mount a volume on a drive connected to my Mini. I also made a similar one to eject it. I use them as Calendar-triggered events as part of my backup scheme.
They work well ... until I restart the Mini, when occasionally my two connected drives will mount in a different order. What happens then is that the sequence of mouse clicks recorded in Automator don’t find the correct volume.
I wonder if there’s a better way to automate the mounting of a currently ejected disc (and later its ejection). Automator, as far as I can see, does not have the actions I need. It has Ask For/Connect to/Get specified Servers, but they seem only to be for network-connected stuff.
Anyone know a better way?

Welcome to Unix.
The key part of that shell script code is the test for the existence of the mount point (if [ -e /Volumes/dbamp ]), followed by a conditional block that — in the "else" section involved when the mount point wasn't found — creates it, and then mounts an AFP file system on that mount point. Most of the rest of the baggage in that script is used to get the mysqldump database dumps over onto the target disk, once it's been mounted.
Here's a very quick overview of the basics of scripting , Apple's introduction to the command line manual, there's a generic bash intro (which is good, but doesn't line up exactly with how bash is implemented on OS X) and O'Reilly has some reasonable books on bash and bash scripting. Once you know and are comfortable with the basics, there are advanced bash guides available.
