Interactive X-Y Co-ordinate system

Hi
Actually I want to have an Interactive x-y Co-ordinate system(having adjustable grid) where I can place arcs and lines at specified angles and position. Along with that we can also can fill out each grid cell with some value.
Is that much interaction is possible with LabVIEW. Please help me out.
Regards
Gaurav Sharma

Use this javascript:
var mouseX = 0;
var mouseY = 0;
function mouseXY(e) {
   if (IE) {
      mouseX = event.clientX + document.body.scrollLeft
      mouseY = event.clientY + document.body.scrollTop
   } else {
      mouseX = e.pageX;
      mouseY = e.pageY;
// set up mouse movement capture for tool tip placement
var IE = document.all?true:false
document.onmousemove=mouseXY;Then just use mouseX and mouseY wherever you want to find out the current mouse position.

Drawing quadratic equations on a 2D cartesian co-ordinate system

Hi,
I need to design a 2D cartesian co-ordinate system to plot quadratic equations on the graph using pure action script. Quadratic equations are of the form y = ax^2 + bx + c where a,b and c are the variables for which the values need to accepted from the user as input. Accordingly, the curve needs to be plotted on the graph.
Could anybody kindly help me to write an action script 3.0 code to suffice the above requirement?
Thanks in advance.
Cheers,
Pratik.

that will take more work than doable in a forum. to start, you need to find the roots of your equation (use the quadratic formula) and make sure the real roots are towards the center of your x-axis. the two parts where y tends towards (+infinity or -infinity) do not require much display.
if there is only 1 or 0 roots, put that equation in vertex form and use an x-axis centered around the vertex.

AWT co-ordinate system

Hello.
I still can't figure out. I'm plotting graph co-ordinates on an AWT Canvas component. i.e (x,y) values
However, due to the AWT co-ordinate system, the origin (0,0) is at the top left hand corner of the screen.
What trick can I do to plot my points with
respect to the origin at the BOTTOM left hand corner of the canvas?
I am using the fillOval() method to display the points on the canvas. (See code below)
All I want to do is reverse the direction
of the y axis. Some sample code would be very much appreciated.
A.
My paint code is as follows ...
<code>
public void paint(Graphics g)
// Paint the means
g.clearRect(0, 0, 600, 500);
 if (firststep)
 db.paint(g);
else
for(int i = 0; i < nk; i++) {
g.setColor(cl);
Point p = (Point) means.elementAt(i);
// System.out.println("mean = "+p);
 g.fillOval( (int) (p.xVal()*600)-PtSize/2, (int) (p.yVal()*500)-PtSize/2, PtSize, PtSize); // Draw an oval
 String s = "k= "+ i+ "[" + round(p.x, 2) + " , "+ round(p.y, 2) + "]" ;
 g.drawString(s, (int) (p.xVal()*600)-PtSize/2 + 10 , (int) (p.yVal()*500)-PtSize/2 + 15 );
// Print the cluster
Vector cluster = (Vector) clusters.elementAt(i);
int size = cluster.size();
for (int j = 0; j < size ; j++ )
 p = (Point) cluster.elementAt(j);
// g.setColor(Color.green);
// g.fillRect( (int) (p.xVal()*600)-PtSize/4,(int) (p.yVal()*500)-PtSize/4,PtSize/2,PtSize/2);
// g.setColor(cl[i]);
 g.fillOval( (int) (p.xVal()*600)-PtSize/4, (int) (p.yVal()*500) -PtSize/4,PtSize/2,PtSize/2); // Draw circles to represent the points
// g.drawString(i+"",(int)p.xVal(), (int)p.yVal());
}</code>

An example without axises or labels:import java.awt.*;
import javax.swing.*;
public class Test extends JFrame {
 public Test () {
 setContentPane (new GraphPanel ());
 setDefaultCloseOperation (EXIT_ON_CLOSE);
 setTitle ("Graph example");
 pack ();
 setLocationRelativeTo (null);
 show ();
 public class GraphPanel extends JPanel {
 public void paintComponent (Graphics graphics) {
 super.paintComponent (graphics);
 // y = x^2
 Point previousPoint = null;
 for (int x = 0; x <= getWidth () / 10; x ++) {
 int y = x * x;
 Point point = new Point (x * 10, getHeight () - y);
 if (previousPoint != null) {
 graphics.drawLine (previousPoint.x, previousPoint.y, point.x, point.y);
 previousPoint = point;
 public Dimension getPreferredSize () {
 return new Dimension (200, 400);

PageItem Co-ordinate w.r.t. Spread Co-ordinate System

Hi All, I am trying to get coordinates of text frame with respect to spread co-ordinate system. I have used following code for this: InterfacePtr<IGeometry> frameGeometry(textFrame, IID_IGEOMETRY); PMRect frmRect = frameGeometry->GetPathBoundingBox(); ::InnerToParent(textFrame, &frmRect); Here textFrame is the ITextFrame pointer of which I want to get coordiantes w.r.t. Spread. The problem is dimensions in frmRect doesnot change even after transformation using InnerToParent(). Can anyone suggest me in this regard, where I am wrong? - Pete

Hi Pete,
I think your problem is that the parent of kMultiColumnItemBoss or kFrameItemBoss (the only bosses that could store the ITextFrame interface you start from) is kSplineItemBoss and not kSpreadBoss. With your call to TransformUtils::InnerToParent you are likely getting the coords in the spline item's coordinate space and not in the spread's one. The SDK documentation specifies that "The parent coordinate space is the first ancestor boss object on IHierarchy that has an IGeometry interface".
HTH,
Emanuele.

Georeference cartesian co-ordinates to standard co-ordinate system

We have set of old maps which do not follow any standard co-ordinate system and they are just cartesian grid co-ordinates (for example lat,long 40.733828,-73.988414 corresponds to cartesian co-ordinates 1610350, 1114450) . I want to explore a possibility of applying simple transformation and geo-reference it to standard co-ordinate system. I can have little compromise on positional accuracy. What is best available method to do it oracle spatial?
Thanks

Well...
One approach would be via EPSG method 9621. Unfortunately, 9621 is not yet implemented, at this point.
Another approach is via NADCON, although NADCON was not semantically meant to be used in this way. If you can determine (lat, lon) and (x,y) exactly along the 4 corners of your unknown map, we could use the NADCON method. It is difficult to say how much accuracy you would get with these 4 points. The accuracy would increase with an equi-spaced grid of n x m known points.
Yet another approach would be that we simply assume a transverse mercator projection. Since your map only covers Manhattan - who will see the difference between transverse mercator or anything else (assuming that the projection center is near Manhattan)? But it is a little more complex, of course. First, we would need to perform a datum transformation with the required rotation. This would simulate the rotation of the map you talked about. Then we would perform a transverse mercator projection with its center near Manhattan. We would have to assume that your unknown projection also had its center near Manhattan (resulting in minimal distortion, there). This assumption is reasonable for a map of this scale.
If you give me approximately 5 points for which you know lat/lon and x/y, I will see what I can do. Usually, we do not do this, and it will certainly take a few days, for I will have to fit it into my schedule.
Also, a reasonable result will only come out if our assumptions regarding this unknown projection are mostly true.

Support for Co-ordinate system?

Does anyone know whether Oracle Spatial supports the mapping co-ordinate system used in Romania (Stereo70)?

Yes, this SRID is based on the EPSG projection method 9809 ("Oblique Stereographic"). If you are not sure whether this is the SRID you need, do you also have some numeric parameters?
SQL> select wktext from cs_srs where srid = 31700;
WKTEXT
PROJCS["Dealul Piscului 1970/ Stereo 70", GEOGCS [ "Dealul Piscului 1970", DATUM
["Dealul Piscului 1970 (EPSG ID 6317)", SPHEROID ["Krassowsky 1940 (EPSG ID 702
4)", 6378245, 298.3]], PRIMEM [ "Greenwich", 0.000000 ], UNIT ["Decimal Degree",
0.01745329251994328]], PROJECTION ["Stereo 70 (EPSG OP 19926)"], UNIT ["Meter",
1]]
SQL>
By the way: the WKT is relatively short, and does not contain projection parameters. This is because the 9809 method is not mapped to a legacy projection, and thus the legacy parameters for this projection are not available. The EPSG parameters are in the SDO_COORD_OP_PARAM_VALS table.

Save an image from interactive form to R/3 system table

Hi to all,
my scenario is this: Web AS 7.0 (probably patched to the last available patch), NWDS 7.0 and, at the moment, a 4.6c R/3 backend system (within some months we will upgrade to ECC 6.0). I have an online interactive form with some input fields and a user, logged in, fills these fields and pressing the "Submit to SAP" button will save the datas to a custom table on 4.6c backend. All this is simple and is working, but my problem is that one of these fields is an image. The purpose is that the user click on the image field and load an image from local PC and then, pressing submit to SAP button, will save the image on the custom table.
How can I make this? Which kind of context I have to bind to the image field? I have to add a java script/form calc code to image field? And to backend side, how can I do?
Thank you very much in advance,
Enrico

Hi,
In your forms you got the image or a link to the image ? If it's the image the field is define as an XSTRING is supposed. If yes you can add it easily in a database table.
If it's a link, your SAP system ( 4.6 C ) need to the the repository where the image is and then you can add it in the database.If you SAP system doesn't see the repository it's impossible to do so.
Hope this help you.
Best regards

Shifting of GUI Co-ordinate system when Mouse clicked

In my JDK 1.2.2 / Swing based application I have this problem of change in coordinate values (x,y) when a mouse click is used. This problem occurs sometimes and reason cannot be traced.
For e.g. If a user clicks "on" a Button the button is not affected , but the Button is pressed when the user clicks just "above" the button. When this problem arises it happens for all GUI components in the screen like textfield , combobox , table rows etc.
I hope the forum has answer / hint for this untraceable & intermittent problem.
Thanks in advance

1) What OS are you using?
2) Did you try the app on a different machine?
- If yes, and it worked OK, make sure you have the newest video drivers installed on your system.
- If no, then beg/steal/borrow another machine to try it on, or:
3) (better still) post your entire code if it's not too big, or failing that, post a compilable/runnable subset of your code which shows the same behavior, so we can try it out.

Can't interact with iCloud preferences in system preferences!

Since installing Maverick on my Imac 2 weeks ago I have had issues with the Icloud preferences in system preferences. I click on the icon, nothing happens, same with the internet account button.
I have been through the process of deleting the icloud folder from the application support folder and restarting, I can access icloud preferences on the restart and log in but it works for an hour or so, some times longer but have to go through the process again.
Other symptoms are mail not recieving new mail or being able to send, and having to force quit safari when I shut down imac. these are tempoarily resolved when I go through the above process.
This is the first recurring problem I have had in a lifetime of Mac use.
Any clues on how to fix?
Cheers
Rob

I figured out how to solve the problem. I guess the JavaScript engine in Safari is more robust. IWeb wraps HTML snippets in more JavaScript. I updated the webpage to include the original JavaScript from PollDaddy and the poll now works. Here's the URL:
http://somerville-cya.dyndns.org/Activities.html
Notice 1) I modified the original iWeb code to include my own javascipt effect. 2). The PollDaddy code is shown directly in the page while other snippets are in their original iWeb form.

Learning Co-ordinate System - Problem

Hi
I created a sample project to epxlain my problem.
There are two canvases in the main application. outerspace canvas and innerspace canvas.
innerspace canvas has a visual component "mainBox"
and there is also a visual component in outerspace canvas named "overBox"
now i want user to map the x-xis and y-xis of overBox to mainBox, so when user will click re-arrange, overbox will completely cover the mainBox.
This is actually a problem of different co-oridatane systems and i dont know how to map them into one.
Here is the code.

Thanks

Just see below. But it won't work if you resize the view, as one is centered
private
function arrange(event:MouseEvent):void
// Get mainbox coord in local system - i.e. relative to innerSpace
var p1:Point = new Point(mainBox.x,mainBox.y);
// Convert it to global coord from innerSpace
var p2:Point = innerSpace.localToGlobal(p1);
// Convert it to local coord - relative to outerSpace
var p3:Point = outerSpace.globalToLocal(p2);
overBox.x=p3.x;
overBox.y=p3.y;

Interaction iExpense with a thierd system

I am searching technical informations concerning the integration of iExpense with a third system.
The required goal is to be able to create automatically in iExpense an expenses note and pre-populate the corresponding lines concerning the expenses carried out in the third system.
Thus, the user does not have any more that to fill the expenses made in addition. I know that this system is already used by credit card integration : the statement of the purchases makes by credit card is used to create an expenses note in iExpense avoiding a recapture of the infos.

Thanks for posting your problem and investigation, I came across the same issue and built upon your research.
From it, I found a solution to the problem involving controlling the serialization of the EclipseLink OptomisticLockException via the PropertyProxyRegister/BeanProxy classes, and specifically omitted the SESSION and QUERY atributes which seemed to be the offending classes causing the Runtime exception.
I posted details over here: http://www.eyelock.net/blog/post.cfm/controlling-serialization-of-java-objects-in-lcds-or- blazeds

BPM - Interact with external system

Hi Experts,
We are implementing a project with BPM Suite Version 1.1.1.6 (PS5). A requirement is the following things:
- The BPM process begins through a human task.
- Upon completion of the human task, the flow must interact asynchronously with an external system through a webservice. The BPM system sends data to external system.
- The user interacts with the external system and runs a couple of tasks.
- After completing the activities in the external system, the BPM should be receiving an event to continue with the main flow was in wait.
The question is....as an external system can reactivate a BPM process that is in wait hoping the event.
Thank you very much.

Investigate the use of the Call activity. If the external process is long-running, you might use a Service activity in conjunction with correlations.
