Getting object from Set
Hi guys, first post, needless to say im a student :].
Here's my problem:
Firstly i create an ArraySet as follows: SetADT myDeckOfCards = new ArraySet();I then add 52 "playing cards" to the set like so : myDeckOfCards = CreateCards(myDeckOfCards, "Hearts");The CreateCards method creates objects of type Card and adds them to the Deck set.
The Cards class has three values: type, value and suite.
Now my problem is I need to remove cards and then gain access to their attributes.
I thought i could go:
Card myNewCard = Card();
myNewCard = myDeckOfCards.removeRandom();...but this has an error 'incompatible types'. If i assign the randomCard to an object is works fine but then i don't have access to the Card methods.
How would I get the Cards stored in myDeckOfCards as Card objects and not just Objects?
I tried casting but had no luck there either.
Any help would be much appreciated, I realise this is probably something really stupid ><.
Thanks

Doh!
Just got it working, my casting syntax was a bit off. Until next time :]

AjouterCellule(objectadded ,lig,col,recupererAdresse(env,obj));
// this is a method created to save the ovject in my list
// ( in Ajoutercell a save my object like this
List->element = val;
struct list {....
jobject val
]*list;
the code work good if i use jint
--- and this is the method to getobject

thanks to you -
I need to get the Excel.application object from a window handle using AccessibleObjectFromWindow. I can't seem to make the code work. First, I successfully search for the XLMAIN windows. Then, when I get a handle, I execute the AccessibleObjectFromWindow
function. It seems to return a value of -2147467262 in all cases. Therefore, I believe that it is returning an error value. I can't figure out how to determine the meaning of this value.
If it is an error value, I believe that one or more arguments are in error. My best guess at present is that the GUID argument is incorrect. I have tried two GUID values: {00020400-0000-0000-C000-000000000046} and {90140000-0016-0409-0000-0000000FF1CE}.
I have seen both used in conjunction with OBJID_NATIVEOM. Neither one seems to work. I really would prefer not to use the second one as it has an Excel major and minor version number. I would hate to have to change this code, if a new minor version appeared.
The attached code has been commented to show which parts have been shown to work and which not. I'm at my wits end and really need help.
Thanks

Note as written if an instance does not have any loaded workbooks a reference will not be returned (though a workbook can be added using DDE, but convoluted!)
FWIW there are two other very different approaches to grab all running Excel instances though something along the lines of the above is simplest.

How can I get the Doc object from any other object?
Dear colleagues,
in FrameScript it is dead-simple to get to the document part of any object, just add .Doc to the variable.
How can I achieve the same with ExtendScript? I amtired of passing the document object next to AFrames or Pgfs along into subroutines, because those objects already contain the information about their document. But how do I access this?
Thanks for pointers,
- Michael
PS: Almost the same is true for the page an object lives on. With FrameScript we use .Page, with ExtendScript you have to move up the object tree until you reach the UnanchoredFrame.PageFramePage…
PPS: It would be great to see some convenience properties like .Doc and .Page implemented natively.I'll preface this response by admitting this far from an elegant solution, but I did write a function addressing this question, mostly as an exercise.
If passed an object with an InTextFrame property (Pgf, AFrame, Cell, Fn) that resides in an open document, the function will return the Doc object. Otherwise, it returns undefined.
function getParentDoc(testObj) {
//Get object for current page
try { var curPage = testObj.InTextFrame.FrameParent.PageFramePage; }
catch(er) {return;}
//Step backwards to first page in document
var prevPage = curPage.PagePrev;
while (prevPage.ObjectValid())
curPage = prevPage;
prevPage = prevPage.PagePrev;
//Compare with first pages of open documents
var testDoc = app.FirstOpenDoc;
while (testDoc.ObjectValid())
if (curPage.id==testDoc.FirstBodyPageInDoc.id) return testDoc;
testDoc = testDoc.NextOpenDocInSession;
return;
To your PPS: Rather than seeing the native framework grow bloated to address additional features, I would love to see Adobe and other developers publish libraries of useful functions and class extensions. -
How can I get the underlying object from the ObjectReference
Dear friends,
I think this question has been asked a couple of times. But, I am still wondering if anybody has found an answer to it. Maybe this is some common need ...
I would like to get the underlying object for which the ObjectReference is
a mirror For example, I have a class Customer in my application, and I can get an ObjectReference through JDI during runtime. But how can I get the target VM's object which is a real instance of Customer, by which I can invoke methods defined in Customer?
Thank you so much for any input!

How can i set action on UITaBar and get event from that
Hi All,
I m doing one apps in which i have to add three UITabBarItem and this is UITabBarSystemItem.
Now i cannot understand that how can i set action and get event from the?
And how can i set various views on three tab bar item.
I have to use UITabBar means i have to use UINavigationController+UITabBar
My code id
tabBar =[[UITabBar alloc] initWithFrame:CGRectMake(0,370,320,50)];
tabBar.backgroundColor =[UIColor blackColor];
UITabBarItem *search =[[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemSearch tag:0];
UITabBarItem *recents =[[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemRecents tag:1];
UITabBarItem *favorites =[[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFavorit es tag:2];
tabBar.items =[[NSArray arrayWithObjects:search,recents,favorites, nil] retain];
tabBar.selectedItem = search;
[myView addSubview:tabBar];
[tabBar release];
I add a action:
UITabBarItem *search =[[UITabBarItem alloc] InitWithTabBarSystemItem:UITabBarSystemItemSearch tag:0 action:@selector(select:)];
So it error: Warning -no'InitWithTabBarSystemItem:tag:action:' method fount
So any can help me regarding it?Thanks RickMaddy very much.
I read and do with sample at the View Controller Programming Guide . But when run it only view TabBar with title but haven't got any TabBarItem on it. I searched a few example about TabBar and i did, but i want do a form with a button then press on button it view a form with 2 TabBarItem on TabBar and press each TabBarItem will show correlative form page 1, page 2.
UITabBarController *tabBarControl = [[[UITabBarController alloc] initWithNibName:nil bundle:nil] autorelease];
tabBarControl.title = @"Tab bar";
ViewControl1 *view1 = [[[ViewControl1 alloc] initWithNibName:@"ViewControl1" bundle:nil] autorelease];
ViewControl1 *view2 = [[[ViewControl1 alloc] initWithNibName:@"ViewControl2" bundle:nil] autorelease];
tabBarControl.viewControllers = [NSArray arrayWithObjects:view1,view2,nil];

Client unable to get the javax.activation.DataHandler object from Server
Hi All,
I am trying to download the file from the server to the client using Javax.Activation.Data Handler object with IBM web services. But server always returning the Data Handler object is null. I am wondering why it is behaving like this.
My requirement is add the file to the Data Handler object from the server and read the same from the client. But I am always getting Data Handler object is null at the client place.
Please see the client side code and server side code below.
Server side Code:
This is the simple web service method, its creating the Data Handler object and adding it to the Hash Map and returning the Hash Map object to the client.
public Hashtable download()
DataHandler dh = null;
HashMap hashMap =new HashMap();
try{
//Sample test files contains data
String downLoadFName="C:/ADP/downLoadData.txt";
//Creating the DataHandler Object with sample file
dh = new DataHandler(new FileDataSource(new File(downLoadFName)));
//Keeping the DataHandler object in the HashMap.
hashMap.put("DATAHANDLER",dh);
//keeping the sample test message object in the HashMap
hashMap.put("TEST","Keeping the DataHandler and test messages in the hashTable");
}catch(Exception e){
logger.error("Error :while sending the data:"+e.getMessage(), e);
//retrun the HashMap object to the client.
return hashMap;
Client Side Code:
This is the simple client code, and connecting to the server and invoking the web service method
//This is the client code,Just invoking the webservice method from the Webspehre server.
public class WebserviceClient {
static DocumentTransfer controller = null;
public static void main(String args[]){
DocumentTransferService service = null;
try{
//Creating the service Object
service = new DocumentTransferServiceLocator();
//Getting the Server connection
controller = (DocumentTransfer)service.getDocumentTransfer(new java.net.URL("http://localhost:9081/eNetsRuntimeEngine/services/DocumentTransfer"));
//Calling the download method from the server and it returns HashMap object.
HashMap hashMap = controller.download();
//Getting the DataHandler Object from the HashMap
DataHandler dh=(DataHandler)hashMap.get("DATAHANDLER");
System.out.println("DATAHANDLER: :"+dh);
//Getting the String object from the HashMap.
String message=(String)hashMap.get("TEST");
System.out.println(": :"+message);
}catch(Exception e){
System.out.println("Exception :Not able to get the file :"+e.getMessage());
Could you please give me some inputs on this?
Thanks in advance,
Sreeni.Hi Stif,
Thanks for your response.I did debug from server side,it has printing content of Data Handler properly.
Also i have debug request and response messages using TCP/IP monitor(RAD environment has this feature).The response from the server is going proplery.
But the client side Data Handler is coming null.
Any advice or solution would be greatly appreciated.
Thanks,
Sreeni. -
I have set up iCloud on my iPad as instructed. When I try to login to iCloud from safari on my iPad I get redirected to set up iCloud on this iPad.
How do I solve this?
iPad 2, iOS 5.0.1If you upload a document from your computer to your iCloud account, the document automatically appears in the app on the iPad - If the app works with iCloud.
You can't log into iCloud and transfer just any and all documents from your computer to the iPad. That's now how iCloud works. You have to upload all of the compatible files into iCloud before you get to the office and then the files will be accessible on your iPad.
There are really only a few apps that even work with iCloud in this manner right now, the Apple iWorks apps work with iCloud, so once again - at this point in time - given the way that iCloud works - there is no reason to log into your iCloud account on the iPad. You have to understand what iCloud does and how it works and I think then it makes sense as to why you don't need to log into iCloud on the iPad. -
Setting the name of a new object from a string
Is there anyway I can set the object name of a newly created
object from a string?
eg.
(the code below generates a compile time error on the
variable declaration)
public function addText(newTxt:String, txt:String,
format:TextFormat):void {
var
this[newTxt]:TextField = new TextField();
this[newTxt].autoSize = TextFieldAutoSize.LEFT;
this[newTxt].background = true;
this[newTxt].border = true;
this[newTxt].defaultTextFormat = format;
this[newTxt].text = txt;
addChild(this[newTxt]);
called using>
addText("mytxt", "test text", format);
I could then reference the object later on without using
array notation using mytxt.border = false; for example
There are many a time when I want to set the name of a new
object from a string.
In this example I have a function that adds a new text object
to a sprite.
The problem is, if I call the function more than once then
two textfield objects will exist, both with the same name. (either
that or the old one will be overwritten).
I need a way of setting the name of the textfield object from
a string.
using
var this[newTxt]:TextField = new TextField()
does not work, If I take the "var" keyword away it thinks it
a property of the class not an object.
resulting in >
ReferenceError: Error #1056: Cannot create property newTxt on
Box.
There must be a way somehow to declare a variable that has
the name that it will take represented in a string.
Any help would be most welcome
ThanksUsing:
var this[newTxt]:TextField = new TextField()
is the right approach.
You can either incrment an instance variable so that the name
is unique:
newTxt = "MyName" + _globalCounter;
var this[newTxt]:TextField = new TextField();
globalCounter ++;
Or store the references in an array:
_globalArray.push(new TextField());

I have created a movie application and i have a JList displaying all registered movies, it uses a DefaultListModel to display these.
I want to be able to click on an element in the JList and then push a button called "Show movie details" to display all information about the selected movie.'.
Every new movie is added to the DefaultListModel as an object with "Titlle", "Genere" etc. If someone click on a movie, what do i do to get information about which object that was clicked. All i can see is that integers can be returned with the getSelectedIndex/Value methods. If i use one of these methods to get the object from the DefaultListModel, that would work i guess, but what when someone deletes a movie in the middle of the JList, then the indexes wouldnt match.
Can someone help me out here? :)I get a big fat exception when trying to cast the returned object to a Movie object which im using.
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: java.lang.S
tring cannot be cast to Movie
...sure that this is the way to do it? If so, what am i doing wrong..
