Binding Syntax Question

Hi,
Can you tell me what the "data:" does in the following binding expression:
protected function vehiclerequestform1_vehicleRequestEventHandler(event:VehicleRequestEvent):void
vehicleService.addVehicleRequest({data:event.vehicleRequestData});
I'm not seeing data defined anywhere (in this working example), so I was curious what this does.
Thanks

I see, thanks. So in this case the {} isn't a binding expression at all, but intead the creation of an anonymous object (as
_spoboyle also pointed out), where the significant part is just assigning some object a property, in this case the "data" property? I guess that's because the addVehicleRequest function expects some object with a data property, ... this function will check for that.

Before you go to the trouble of going through all those steps, be warned that attempting to use Dreamweaver CS4 with SVN could even cause Dreamweaver to crash after updating to SVN 1.6.2. I, too, have abandoned SVN integration with Dreamweaver until the problems are sorted out. I reported this problem to Adobe a couple of weeks ago, and spent a long time working with an Adobe engineer, who was able to reproduce the problem, but not offer a solution. Hopefully, the next version of Dreamweaver will have more robust support for Subversion.

More syntax questions about nested symbols

I have a symbol timeline that does everything I need it to do except to access a function within the stage symbol. I would have thought that calling the function in the stage symbol from a nested symbol (which is loaded dynamically, if that makes any difference) would be something along the lines of:
sym.getComposition().getStage().gotoNextSlide("slide5");
but no luck. I can alert the stage itself as [Object Object], which brings up another question. Is there an always-available property of objects that one can alert or trace to make sure the correct object is being targeted? I've had no luck with the symbol's id, name, or symbolName.

Sure. You've seen one form of the project I'm working on, though I'm at the next speedbump. Here's an excerpt of the involved parts.
I have the stage symbol and within that symbol, I have a function:
function gotoSlide(slideName){
          fadeTo(slideName);
function fadeTo(slideName){
     /// this all works fine, when called from the main timeline
In the composition, I'm loading slides from the library and on the timeline of one of those slides is the following.
navHidden = true;
var trueButton = sym.getSymbol("answers").$("true");
trueButton.bind('click',goNext);
function goNext(){
          sym.getComposition().getStage().gotoSlide("slide_05");
I know there are other syntaxes I could use but refactoring is in the future. The console log I get is:
Object [object Object] has no method 'gotoSlide'
It's slide 5 in these:

A syntaxic question...

Hi guys,
I've posted about this on this very forum before, but I can't find my own question... and the answers that you people provided, so I'll do it again: what's wrong with the following, knowing that I have Developer Tools installed and that I clearly remember writing a script along those lines a long time ago, when I was still using Tiger?
Here goes:
"move mouse
720, 450 {from left, from top}"
Where the goal is to move the mouse pointer center screen on startup (don't bother about compiling and saving as an app, just about the right syntax). Something's missing, but I can't put my finger on it...

The app developer once told me that the delay in activating the mouse was built-in, because it took the Trackpad some time (usually no more than a second or two) to fully activate. So I guess I can't get anything better than what I already have: at least I don't accidentally trigger the Apple menu by trying to move my mouse pointer to screen center...
Well, trying to stress my brain to figure out an impossible solution.
FWIW, here's the code, before modification:
move mouse {720, 450} -- {from left, from top}
click mouse
delay 0.1
click mouse
delay 0.1
move mouse {730, 460} -- {from left, from top}
I'm going to add a two-second delay between the two mouse clicks, just in case. I'll keep you posted. As for the compliment, it's amply deserved, and I'm not the only one on this forum who says so...
I you are trying to simulate a double click, you need to make the delay closer to what a human would do. Two seconds will most likely turn the double click into two single click.

All this is probably not need since you fessed up to it being a driver problem.
Cheers!
Thanks again for your rewarding comments.

11g pivot query syntax question

I searched the forums and I have seen questions similiar to the one I am asking, but its not the exact same issue.
I need 3 fields in my 'for' clause. I get 'column ambiguously defined. I think I get this error for a different reason that other people asking the question.
The others seem to be doing more than 1 function in the pivot clause and those need an alias. I give an alias with my 1 function and still get an error.
ORA-00918: column ambiguously defined
I used aliases like the recommendation in other posts and I still get the same error. I think I need 3 columns in the for clause.
--note that this is just a test table. These are not real names going into production
create table pivot_tab (
pk1 number,
pk2 number,
myElement varchar2(30),
myElementDate date);
pk1,pk2 are the unique key.
I need this to return as: the vlaues after pk2, can be any alias. This is just an example.
pk1 pk2 MY1_DATE, MY2_DATE, MY3_DATE
select *
     from pivot_tab
    PIVOT ( max(myElementDate) for myElement
            in (''MY1','MY2','MY3'))
I saw a couple of references to this syntax, but I get syntax errors.
ora--00906: missing parentheses. So I dont think this syntax works.

            in (''MY1','MY2','MY3'))Edited by: Guess2 on May 6, 2013 6:50 AM

don't have any sample data or expected results to test this with maybe
SELECT *

with pivot_tab as (select 1 pk1, 2 pk2, 'MY1' myelement, sysdate myelementdate from dual union all

Fixing this Scalar Variable Syntax question

Please help me to correct this syntax for this practice question below.
/* Create and set a Variable equal the number of Flights that were late.*/
DECLARE @FlightsLate varchar(50)
SET @FlightsLate = (SELECT* FROM
Flights WHERE Ontime = 0)
SELECT @FlightsLate

If you want to get the total numbers that are late you need to do this
DECLARE
@FlightsLate varchar(50)
SET
@FlightsLate = (SELECT count(*) FROM
Flights WHERE
Ontime = 0)
SELECT
@FlightsLate
Assuming that Ontime =0 means Late

Hi All,
i have written 2 times.
1. sqlite3bind_blob(insertstatement, 1, image, -1, SQLTRANSIT);
it doesn't give compile error but when i run the applilcation it crash the
simulator.
2. sqlite3bind_blob(insertstatement, 1, image, -1);
it gives error like too few arguments.
here image is object of UIImage........
pls anyone can tell me what is proper syntax for binding of blob datatype.
Thankx.
vavdiyaharesh is online now Add to vavdiyaharesh's Reputation Report Post Edit/Delete Message

I wanted to do something similar, but as you mention, there isn't a lot of sample code to copy and paste etc, and I didn't have the time to spend investigating this one issue when plenty of other things needed my attention.
In the end I decided to save my BLOB data as actual files in the document directory and then store a link to these in the database row. Something like primarykey_id_blobname.jpg etc.
Probably not the answer you want, but hopefully it'll get you past a road block and onto the next item on your list.

Binding Basic Questions

Noob questions...
Can you help me figure out why the following won't work for me? I am so frustrated!
//MyComponent.mxml
<VBox:etc...>
[Bindable]
public var url:String;
public function setAndCallService():void {
url = "http://localhost:8888/blah/blah/blah";
serv.send();
<mx:HTTPService id="serv"
 url="{url}"
 result="serv_result(event);"
 resultFormat="e4x"
 fault="serv_fault(event);" />
private function serv_fault(evt:FaultEvent):void {
 trace("serv fault occurred: " + error.text);
 trace("url " + url);
 error.visible = true;
//... the rest of the file ...
What occurs is that the serv.send() gets called, and serv_fault is then called and the first trace line indicates that no URL was given to the HTTPService component. and yet the url gets printed out by the second trace line correctly as "http://....blah/blah".
If you have any extra time, might you be able to explain why if I have [Bindable] set for a private property, why I also need [Bindable] by the getter/setter for that property (and which? the getter or the setter?
Thanks very much.
In addition, if you've got time to explain any/all of the following...
1. I know this is probably very stupid, but if objects are passed by reference in flex, why do i need to bind them? Aren't I always seeing the single instance (and its updates) wherever I have a reference to it (in various components to which i've passed the object)?
2. If i have a private property in a component, can a child component see this private property, or does it need to be made public?
3. If i set a private property to be [Bindable], why then would i also need to add [Bindable] to the getter/setter for that property? And when should i set the getter to Bindable vs. the setter?
Thanks again for all the clarification ahead of time.

1.You don't always need to make use of binding. For instance, in your example, I don't think you need a separate url property and/or binding. Just use the HTTPService's property directly.
2. Other components will not be able to see private properties. So you could make it public or expose it via get/set functions.
3. Because you are actually defining two different properties. The private property and the property defined by the get/set functions.
You probably only need to make the public get/set functions bindable (not the private property). And it doesn't really matter if the [Bindable] is specified before the get/set (in most cases), because it applies to the property, not the functions.
The following documentation may be helpful:
http://www.flexafterdark.com/docs/Flex-Binding
Let me know if that helped at all.

??? a launchd syntax question

When running cron jobs, I think (somebody please correct me if I'm wrong or verify if I'm right) that if a person wants to schedule a job to run monthly, but rather than on a specific date of the month (e.g., 1st, 2nd, etc.), it is desired to have the job run on, say, the second Saturday of the month, (s)he would make a crontab entry that looked something like this:
#minute hour mday month wday who command
36 02 8-14 * 6 root periodic monthly
If I got this down right, this would run "monthly" on Saturday, so long as the date of Saturday was between the 8th and the 14th, inclusive, i.e., the second Saturday of the month.
If this is a correct assumption on my part (to include my assumption on syntax), then comes the question du jour:
How might one modify the /System/Library/LaunchDaemons/com.apple.periodic-monthly.plist file to do the same thing?
Thanx in advance
2001 Quicksilver G4 Mac OS X (10.4.5)
2001 Quicksilver G4 Mac OS X (10.4.5)

I don't believe you can.
The launchd.plist((5) files don't take ranges for dates, or at least aren't documented to.
One other thing to note with periodic launchd(8) events - there's long been an issue in the kqueue(2) call that drives launchd(8) such that event timers don't really work the way the launchd.plist(5) man page says they do. Instead of firing when a machine awakens from sleep if an event occurred while the machine was asleep, events instead only accumulate time while the machine is up and running.
So say, for example, you told launchd(8) you wanted to run a script at 6:00 AM tomorrow morning. You continue using your Mac, but it goes to sleep at midnight and you awaken it from sleep at 8:00 AM.
The launchd.plist(5) man page says the event will be run when the system awakens, but it will not; rather the six hours of system uptime the machine was asleep must elapse first, meaning your "6:00 AM" script will actually run at 8+6 = 14:00, or 2:00 PM.
While this is better than cron(8) which would just ignore the event that occurred while the machine was asleep, it's certainly not the behavior that launchd.plist(5) documents, either…

Please help with an ICM script editor syntax question.

I need to modify a set variable node. What I have now is Call.PeripheralVariable8+".wav" and this works. What I need it to say is Call.PeripheralVariable8+anything+".wav" but when I insert an * for the anything it's seen as a multiplier. What's the syntax to do this? The anything I need to add is _9xxx where xxx are other numbers, but the _9 will be in all, if that helps any. Thanks in advance !!

You can use the concatenate() function to build up your string, as you no doubt know.
As far as the wildcard goes ... your intention must be to try to SET the call variable and later on test the call variable with an IF node. Is that right?
You would be able to test parts of the string using the substr() function - which is based on character position. If that is a fixed value that you know, it's easy. If it's not, you can first use the find() function to locate something (like the "_9"), returning the position, and then use the substr() function to pull it off.
Can you write some pseudo-code here to define exactly your intention? You can set up a dummy script and send a dummy call through using Call Tracer and watch the output to see how your code is working.

Geoff

Simple Task - Syntax Question (how do you pass variables from one component to another component - databinding)?

Hi all,
I'm trying to pass some width/height/URLs from a Video Player component to a Social Bookmarking component's embed text input field. (for people to grab and share videos).
I know this is a simple task, but it's the end of the day and I seem to be having a brain failure... What's the syntax to achieve this? Do I have to import the video player component? These widths/heights/URLs are all being dynamically generated from an XML... should I be pulling it from the XML or just reuse the variables that already exist in the Video Player component?
Here's my code...
Video Player:
[Bindable]
public var source:String = "";
[Bindable]
public var autoPlay:Boolean = false;
[Bindable]
public var fullScreenMode:Boolean = false;
[Bindable]
public var clipTag:String = "_movie";
[Bindable]
public var iag_code:String = "";
[Bindable]
public var officialURL:String = "http://www.movies.com/";
[Bindable]
public var referer:String = "unknown";
[Bindable]
public var gID:String;
[Bindable]
public var starterImageURL:String = 'http://www.movies.com/jazzmaster/images/default_starter_image.
[Bindable]
public var oldWidth:Number;
[Bindable]
public var oldHeight:Number;
Sharing Component:
<mx:HBox
height="10%"
horizontalCenter="-25"
verticalCenter="0"
paddingBottom="5">
<mx:Text text="Embed Code:" paddingTop="1" color="#FFFFFF" fontSize="12"/>
<mx:TextInput text="{oldWidth}"/>
</mx:HBox>
The code above throws an error... "Attempted access of inaccessible property oldWidth through a reference with a static type com:SharingBookmarks."
Thanks all!

Import ASO MAXL syntax question

I have a maxl script I use to load an ASO database. I realize that I need to have not only the load rule set to append data but the import statement as well. I took the syntax straight from the Essbase documentation but I'm still getting an error. Here's my script:
alter database App.DB initialize load_buffer with buffer_id 1;
import database App.DB data from data_file '0947Brand.txt' using server rules_file 'RetailB.rul' to load_buffer with buffer_id 1 on error write to 'RetailB1.err';
import database App.DB data from load_buffer with buffer_id 1 add values;
alter database App.DB initialize load_buffer with buffer_id 1;
import database App.DB data from data_file '0947Generic.txt' using server rules_file 'RetailB.rul' to load_buffer with buffer_id 1 on error write to 'RetailB2.err';
import database App.DB data from load_buffer with buffer_id 1 add values;
My error file shows this as an error:
essmsh error: Parse error near add
Any ideas?

Any ideas?Not sure of the error, but you are not really using buffers efficiently. You should have a single
alter database App.DB initialize load_buffer with buffer_id 1;
then your two import statements
and finally the
import database App.DB data from load_buffer with buffer_id 1; statement
Your actual import statements should have the add values
When you load multiple files into a buffer at once, it takes and adds the intersections together automatically. you only need the add values if you want to add the values to existing values in the cube.

Simple database query syntax question

Hi experts,
I am just stucked here...
e.g.
String Name = "John Doe";
String query =
"select * from table where NameCol = "+Name;
ResultSet rs =stmt.executeQuery(query);
while (rs.next()) {
System.out.println(rs.getString(NameCol);
The complier complains that "Syntax error !" at
" NameCol = ....." ?!?!
Why this is happening ? What is the correct syntax ?
Thanks in advance !
Philip

finally figured it out. thanks...

Formatted search with UDF and syntax question

Can you explain the syntax with when to use the dollar sign and negative in writing a query for a formatted search based on user entry?
I now want to create a formatted search to pull values based on the user's entry into a UDF on the item master screen.
User entry into UDF U_Customer Code
to create Formatted search for UDF U_Rep01
I tried the following, but it does not work.
SELECT T0.U_REP01 FROM dbo.OCRD T0
WHERE T0.CARDCODE = $http://$OITM.U_CUSTOMERCODE
Thanks.
Please advise.

The right syntax would be like this:
SELECT T0.U_REP01 FROM dbo.OCRD T0
WHERE T0.CARDCODE = $[OITM.U_CUSTOMERCODE\]
However, the logic of query may not be correct. Select something must be already in the system and Where should also be locatable.
Thanks,
Gordon

Pl/sql function returning query - syntax question

Hi,
I'm trying to figure out the syntax for the following query:
BEGIN
RETURN 'select name from table1 where name like '%' || :p1_name';
END;
It doesn't work because of the single-quotes around the % sign, plus the quotes for the query itself. How can I handle the % sign quotes? Any suggestions would be appreciated!
Thanks,
Nora

Nora,
If you want to use quotes within a quoted string, you have to duplicate the quotes.
BEGIN
RETURN 'select name from table1 where name like ''%'' || :p1_name';
END;
Fred.
