Possible to create an object from a String?

Hi,
is is somehow at all possible to create an object from a String ?
If we have etc.
String txt = "Carrot()";
Is it then possible to somehow cast that String and interpret it as a class type that it should make an object of ?
Like
new txt; - would then give me the same as new Carrot(); ?
Hope you understand what i mean.

Class.forName("some.package.Carrot");

Can you create an object from a string

I have been working on creating a dynamic form, creating the
form items from an xml file. I am getting very close to conquering
this task. I will share it when it's complete.
However, I am stuck at the moment trying to create an object
from a string. For example, if the xml item is an HBox I want to
create an HBox. Like this: parentObject = new arrayOfFormItems[
index ]..type ()
This isn't working. First, is this possible using some syntax
I am unaware of in Flex? I don't want to use a large if or case
statement if possible.
Thanks in advance for your help!

Thank you very much. Indeed that did solve the one problem. I
missed the casting as a Display Object. That is awesome!
I do still however, have to instantiate one of every item I
want to dynamically create or I get the following error when I try
to create a dynamic object that I have not instantiated before.
ReferenceError: Error #1065: Variable HBox is not defined.

I read that you have no choice but to instantiate one of each
type to force the linker to link the code for that class into the
.swf. Unless you know another way to force it.
This is what I have in my Application mxml to get it to work:
<mx:HBox>
<mx:Text visible="false"/>
<mx:TextArea visible="false"/>
<mx:TextInput visible="false"/>
<mx:DateField visible="false"/>
</mx:HBox>
And those are the types I'm using to test with. . . I will
have to add all the others I want to use as well . . .

How to create a Document object from a string.

If I use the following code, the input String cannot contain "\n", otherwise, it generates errors.
in the following code, inputXMLString is a String object that has xml content.
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(inputXMLString))); How can I create a Document object from a string with "\n" in the string?
Thanks.

If I use the following code, the input String cannot
contain "\n", otherwise, it generates errors.That's going to be a huge surprise to thousands of people who process XML containing newline characters every day without errors.
Perhaps your newline characters are in the middle of element names, or something else that causes your XML to be not well-formed. I'm just guessing here, though, because you didn't say what errors you were getting.

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
Thanks

Using:
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());

Dynamically create Value Objects from XML file

Hi
I want to create a value object from Xml file dynamically,like in the xml file i have the name of the variable and the datatype of the variable.is it possible do that,if so how.

Read about apache's Digester tool. This is part of the Jakartha project. This tool helps in creating java objects from the XML files. I am not sure, if that is what u r looking for.

Create Class objects from an Array of File Objects

Hi There,
I'm having extreme difficulty in trying to convert an array of file objects to Class objects. My problem is as follows: I'm using Jfilechooser to select a directory and get an array of files of which are all .class files. I want to create Class objects from these .class files. Therefore, i can extract all the constructor, method and field information. I eventually want this class information to display in a JTree. Very similar to the explorer used in Netbeans. I've already created some code below, but it seems to be throwing a NoSuchMethodError exception. Can anyone please help??
Thanks in advance,
Vikash

It's throwing the exeption on the line:

I'm sure its something to do with the extended class i've created. but i cant seem to figure it out..
Thanks if you can figure it out

How do I create an object from a filename?

I'm traversing directories and storing a list of files in a File array. Then I traverse the array looking at the extension of the file. If it is .java then I would like to instantiate it as a class so that I may pass the new object to another function which will examine its methods. I've tried Class.forName(file.getCanonicalPath()) and it throws a ClassNotFound exception. How can I create an object from a valid filename, please?

Rick_Avlonitis wrote:
If it is .java then I would like to </snip>.java files contain source code, they can't be "instantiated". Class.forName() takes a classname as parameter, i.e. "mypackage.MyClass". A class name is not a file name, and it doesn't have an extension. As stated in the other reply, you'll need to have the class on your class path.

How to create session id from different string controls

how to create session id from different string controls

fais,
Please create the VI you are talking about and save some default data into all of the controls. Also on the front panel, place the session ID that should be generated by that data. Now, post your VI to a response so I can download it. I can then take this VI and help you create the functionality. (Please post what version of LabVIEW you are using.)
My guess it that you are going to need to use a good number of string concatenations as well as a few string indexes to get parts of strings out. As for the date, you can use a Property node with the Numeric Text.Text property to get the actual string displayed on the front panel for the date and parse out the parts that you want.

Is it possible to clone an object from one image and paste it on another image?

Is it possible to clone an object from one image and paste it on another image in Aperture?

As Frank said,
but Aperture has a nice clone tool - the drawback is, that it only works within one image.
What I sometimes do - as a workaroud, when I want to use the clone brush, is to combine the image I want to clone from and the image I want to clone into, into one single image by printing them together to pdf as jpeg. Then I can clone from the second to the first, for example, to be able to add an fairy to a flower: Picking up the head of the fairy in the right image and brushing it into the left one. Occasionally I prefer the Aperture brush to the Photoshop lasso.

Is it possible to create an activity from the Agenda?

Hi Experts,
We noticed that it's possible to create a note from SSC1 Tcode but not an activity.
When we create an activity (appointment), it appears in the agenda but we can't manage to create it from the agenda.
Is there any possibilities ?
Many Thanks
Laurent

Hi,
You can create the activity by double clicking on appointment calendar.
Go to Tcode : crmd_order and select calendar tab.Double click on any time of the calendar and select the appropriate transaction type for activity.
Then you will be able to create the activity.
If helpful kindly reward me.
Thanks & Regards,
Anirban
