Can't use a vector as dataprovider in a datagrid

It appears that you can't use a vector as dataprovider in a datagrid. Am I correct?

You are correct.
A class must have a certain functionality to be able to work as a dataprovider for the flex components. Vector is not one of them unfortunately.
You can replace your vector with an ArrayCollection or convert it to an ArrayCollection right before setting it as the dataprovider.
I'm not aware of another way of doing this.

How can I use FlexMotion vector move function for cartesian coordinate system to other coordinate.

I have problem with convesion from cartesian coordinate system to other one. I need use standard move function for example blend to moving 2 arms manipulator. What i need to do?

The vector move will probably not give the results you are looking for. The vector move calculates the trajectory based on unit vectors in cartesian space. For a 2 arm robot (ex. 2 rotation joints), you would be able to move from point A to point B as desired, however the path would not be a straight line. The path may also not be suitable for the mechanism, which could cause a collision or maybe a singularity.
The best solution is probably the contour move. You can use the inverse kinematic routine you wrote and send the results to a contour move. Contour moves are a little more complicated to use than the simple one axis or vector moves, however they are also much more flexible. I do not know of any functions already written for your system,
but it sounds like you are already on the right path.

Can I use Scalable Vector Graphics (.SVG) in RoboHelp 11 projects?

I need to import .SVGs into my RoboHelp 11 HTML5 project, but that file type doesn't seem to be supported. I tried pasting the appropriate HTML code into a topic, but the SVG graphic doesn't show. Am I missing something, or is there a work-around?

Hi folks
Simple Simon here.
First off, I totally agree with Erik in that you should file a Feature Request.
Secondly, I know that many folks aren't really all that keen on mucking with code. So here's one solution that involves minimal code muckage, (yep, muckage is a technical term. I just invented it!)
Add your SVG to Baggage where you want it.
Insert an image where you want your SVG to appear.
Click and drag the SVG from Baggage to the spot just beyond the image.
Double-click the SVG link and copy what appears in the Link to area. Then delete the link.
Click once on the image, then click the HTML tab.
Now just paste what you copied between the img tags.
Cheers... Rick

Using a vector in Java IDL...URGENT!

How can I use a vector in Java IDL? I am trying to have a function return a vector.
From what I have read, I should use a sequence. Therefore I tried the following code:
     struct ItemDB {
          long ItemNumber;
          long Quantity;
          double Price;
typedef sequence <ItemDB> ItemList;
     interface ProductOperations{
          ItemList listItems();
When the equivalent Java is generated for the interface I am forced to return an array instead. This is what is generated:
public interface ProductOperationsOperations
ItemDB[] listProducts ();
However, this is an array, which is bounded. I want to use an unbounded storage device.
Can someone please please assist me. I appreciate it.
Thanks
RG

This is already an unbounded sequence
typedef sequence <ItemDB> ItemList;
Checkout the read/write methods in the Helper class and you can see that the above list is unbounded.

Where is the Vector class? Can't use it.

Hello!
I've downloaded Flex Builder 3 Trial from Adobe's website.
Now I want to use the Vector class, but this code for example:
var v:Vector.<String>;
v = new Vector.<String>();
Gives me this error:
1046: Type was not found or was not a compile-time constant: Vector.
At the IDE, going to
Window -> Preferences -> Flex -> Installed Flex SDKs
I can see that I have Flex 3.2 SDK.
Even more than that: When I search for "Vector" in the help ("Adobe® Flex™ 3 Language Reference") I can see all the details about Vector.
What can I do?
I'd like to avoid installing any newer SDKs due to all the bugs I see listed here in the forums.
Thank you!

It looks like you are trying to type Java code in Flex Builder. Flex applications are generally built using ActionScript.
These docs might help you learn ActionScript:

I hope that helps...

Can vector CANoe software can be used to integrate with NI XNET?

Can vector CANoe software can be used to integrate with NI XNET hardware?, Is there drivers available for NI XNET PXI card to communicate and talk to Vector CANoe software?. Please help. This would help us reduce creating the Database using LAbVIEW.
_Ventakesswaran

CANoe is essentially made to integrate Vector hardware, so you can't directly use NI-XNET interfaces into your CANoe system. There are still a few ways to communication between LabVIEW (or CVI) and CANoe if you need to share data. It includes :
- Using the ActiveX server of CANoe in LabVIEW. It allows LabVIEW to automate most tasks in CANoe and notably write/read data.
- Writing a server/client code based on TCP or UDP to send and receive data. In LabVIEW, it just uses the primitives in the Data Communication palette. In CANoe, the communication can be handled by some code written in a CAPL node.
The first way is slower, but does not require to write code in CANoe. There are also a few examples going around the web :

Can someone tell me how I can use a Vector to access my class?

I wrote a class that will need to be instantiated with unknown instances later. I decided to use a Vector to do this. However when I created the vector:
<CODE>
Vector user = new Vector(1,1);
user.addElement(Users());
user.elementAt(0).name="Test";
</CODE>
I'm really not sure how I can set this. The class is of course Users and I want to set user as the Vector but specify Users as the Object Type. Any help? By the way I heard Java has a dynamic array feature is this true? I heard you had to use Vectors for Java. Also how can I free up the memory when I'm done with the class?

Suppose class User looks like this:
public class User
public String name;
}then you could do:Vector users = new Vector(1,1);
users.addElement(new User());
((User)users.elementAt(0)).name="Test";BTW - Java is NOT C++, you always need to use the new keyword for object creation!

How can I use the same object in the different jsp files?

I am doing a project. I have finished my jave source files and compiled them successfully. And I also wrote a main method to test my classes, they also worked well. Now I am trying to use my jave code in the jsp files. But I meet a problem, in my method of java source file, I can generate a object of a class, and use it in the whole main method. But in the different jsp files, how can I do same thing?
For example, in the .java file,
Vector vl = new Vector();
While ...{
vl.add(...)
In each of my .jsp file I want to do one loop of the above, meanwhile I want to do that in the same object.
I hope you can understand what I mean. Really need your help!

put your object into a session and you can the use it in all the jsps as long as the session is valid. Or you could create a static variable in the class that only creates one instance off an object and then create a static method to return this object.

How can i use magic wand tool in photo-shop 7 ??

nhmc,

Not with a raster image, like a .jpg. You need to be more aware of the huge differences between a raster image and raster editor, and vecor graphics and a vector editor. Selecting stuff is one of the biggest difference.
In Illustrator, you work with objects, like stacks of paper on a table. You can select individual objects anywhere on the page and on any or all layers, then transform, move, delete, fill stroke, or an infinite number of things to those objects.
In Photoshop, when you select, you are really just creating a mask, which you can then use to restrict editing to pixels within that mask on the current layer. It's like working on a photo of a stack of paper on a table. You can't easily move the pieces of paper around.
It's difficult to explain in a short posting, and that's all I'm going to write tonight. If you intend to spend any time with Photoshop or Illustrator you should invest in some documentation, and I don't mean Adobe's completely insufficient on-line documentation. The Visual Quickstart series comes well recommended and scales easily to intermediate once you know your way around.

How to create spark skins using fxg vector graphics&how to switch b/w spark skins at runtime/via XML

Hi,
I want to create a number of Spark Skins using some vector images that I have with me. I can obtain the vector images in FXG format-- but what I am looking for is some way to quickly create multiple skins for various UI elements like buttons, menus, radio button, checkboxes, etc -- not by converting the fxg->mxml but by using fxg files directly (after including them in the skins project in Flash Builder 4.6). Since I want to create many such skins (atleast 8-10) what is the fastest way of accomplishing this?
Also, once I create multiple Spark Skins, how do I switch from one skin to another, in a running app? -- something like a template switcher, where the user viewing the flex app chooses a color, and the spark skin is immediately changed to the skin of that color (I would have already created the skin...). And can I store this skin template value in an XML? So that the end user can simply change this param in XML to change the design of the flex app?
Arvind.

Follow-up:
Out of pure wishful thinking I decided I would just see what happened if I pretended 'exportFXG' was already a part of JSFL. Based on the signature of 'exportPNG', i tried the following lines:
var success = fl.getDocumentDOM().exportFXG("file:///C:/mySymbol.fxg");
fl.trace("success:"+success); // output: success:true
It worked! Fantastic! I'm not sure if exportFXG is considered still in "beta" and therefore intentionally excluded from the docs, or if it was just an oversight. But at least it gives us something to experiment with.

Use of Vector in undo operation ?

Hello,
I am developing simple paint program. And want to use undo redo operation for drawing in drawing canvas. Actually I have done it with the help of Vector. But the problem is that it is not working properly. The first drawn shape is not removing with this operation and also the problem is that When i am using CTRL+Z for undoing last drawing. It is not removing last drawn shape with first undo operation. Let me know that what is the exact problem in my coding. I am not fully java programmer. So please tell me what to do for that. I want to draw n level of drawing on drawing canvas and also want to perform n level (first drawn shape) undo actions. And also want to know how to make redo button for same coding only use of Vector or ArrayList.

}This is complete code for undoing.
Any help will be appreciated.
Thanks in advance.

The example code is set up for a protocol completely different than what you are doing, so you can't simply copy it and hope it works. The example code expects that the other side will send a 4-byte header containing the number of data bytes that follow, then send the data. The example code first reads that 4-byte header, casts it to an integer, and reads that number of bytes (the second Bluetooth Read).
When you run this with your device, the first read gets your 4 bytes - FF FF 22 33 - and converts that to an integer. 0xFFFF2233 is decimal 4294910515. So you then try to read this huge number of bytes and you get an error - looks like error 1, an input parameter is invalid, because you can't read 4GB at once. You can probably get your code working with a single Bluetooth Read, with a 1 second timeout (because you have a 1 second delay between packets). You'll want to wire in some number of bytes to read that is at least the size of the largest packet you ever expect, but don't use a ridiculously huge number that generates an error. LabVIEW will return as many bytes as are available when the timeout expires, even if it isn't as many as you asked to read (you might also get a timeout error, though, which you'll need to clear). You can then do whatever you need to do with that data - search for FF FF, typecast anything after that to array of U16, display it.
The output of the Bluetooth Read is a string, but it's not text - it's exactly the bytes that were sent. The Y with the dots over it is the way ASCII 255 (0xFF) displays (at least in that font). ASCII 34 (0x22) is ", and ASCII 51 (0x33) is the number 3.

Using a Vector Art File as a matte for an image collage

II have a vector art file of a paw print. I would like to use it with a variety of photos to create a collage. I have the image files selected and the vector art file sized, but what I can't figure out is how to have the images seen ONLY inside each toe/pad of the paw print. Once the file is completed, I would like to be able to flow text around the paw prints so I don't want the entire art board area to be white as this would effect my text wrap properties. Any and all suggestions are welcome!

I developed a Photo Collage Toolkit for Photoshop. I feel its very easy to create PSD templates that can be populated with images.
Photo Collage Toolkit
Photoshop scripting is powerful and I believe this package demonstrates this video showing a 5 image collage PSD template being populates with images:
The package includes four simple rules to follow when making Photo Collage Template PSD files so they will be compatible with my Photoshop scripts.
Size the photo collage templates for the print size you want - width, height and print DPI resolution.
Photo collage templates must have a Photoshop background layer. The contents of this layer can be anything.
Photo collage templates must have alpha channels named "Image 1", "Image 2", ... "Image n".
Photo collage templates layers above the background layers must provide transparent areas to let the images that will be placed below them show through.
There are twelve scripts in this package they provide the following functions:
TestCollageTemplate.jsx - Used to test a Photo Collage Template while you are making it with Photoshop.
CollageTemplateBuilder.jsx - Can build Templates compatible with this toolkit's scripts.
LayerToAlphaChan.jsx - Used to convert a Prototype Image Layer stack into a template document.
InteractivePopulateCollage.jsx - Used to interactively populate Any Photo Collage template. Offers most user control inserting pictures and text.
ReplaceCollageImage.jsx - use to replace a populated collage image Smart Object layer with an other image correctly resized and positioned.
ChangeTextSize.jsx - This script can be used to change Image stamps text size when the size used by the populating did not work well.
PopulateCollageTemplate.jsx - Used to Automatically populate a Photo Collage template and leave the populated copy open in Photoshop.
BatchOneImageCollage.jsx - Used to Automatically Batch Populate Collage templates that only have one image inserted. The Collage or Image may be stamped with text.
BatchMultiImageCollage.jsx - Used to Automatically Batch Populate Any Photo Collage template with images in a source image folder. Easier to use than the interactive script. Saved collages can be tweaked.
BatchPicturePackage.jsx - Used to Automatically Batch Populate Any Photo Collage template with an image in a source image folder
PasteImageRoll.jsx - Paste Images into a document to be print on roll paper.
PCTpreferences.jsx - Edit This File to Customize Collage Populating scripts default setting and add your own Layer styles.

How can I use this arrray?

I have written arguemnts to add severals shapes to the scene(by using createVrmlFromString()), all the shape nodes stored in shapeArray[], now I'd like to use another array(b[]) to get the index of each shape nodes which has been added to the secne, so that I can record the their sequence.
1. Can I use the arguments as following:
shapeArray = {shape1,shape2,shape3.....}
if(clickedButton = shape1)
{ b.add(shapeArray.indexof(0)); b++ }
if (clickedButton = shape2)
{ b.add(shapeArray.indexof(1)); b++}
2. Since the length of b[] is dynamically changed according to the number that the nodes added to the scene, shoudl I use the vector, how can I get the index of the shapeArray to a vector. should I use
Vector b = new Vector;
b.addElement(shapeArray.indexof(0));
b++; //?

I haven't used createVrmlFromString(), but maybe this will help...
Note at Square, Circle, and Rectangle extends Shape.
Shape[] shapeArray = { new Square(0, 0, 10, 10),
new Circle(10, 10, 10),
new Rectangle(20, 20, 150, 100)
Vector clickedShapes = new Vector();
// in the combobox listener
clickedShapes.add(shapeArray(cb.getSelectedIndex()));
// in the 'submit button' actionlistener; get first item
Shape s = (Shape)v.get(0);
