How to store Ellipse geometry
I want to store ellipse geometry in spatial table. How do I do it ? Or the only way is to construct circular arcs or multi-line segments.
-Girish Shewale
Hi Girish,
Oracle spatial doesn't provide a primitive type of ellipse, which leaves you with three options:
1) Use the oracle primitive types to contruct an ellipse (probably a polygon type consisting or straight lines and/or circular arcs).
2) Create your own element type using etype of 0 with whatever information you need to store the coordinates for the ellipse, and add a supported element type which approximates the ellipse so it will be returned appropriately by spatial operators.
3) Create your own element but use a gtype of 0, which means the whole geometry will always be skipped by Oracle spatial routines (won't be indexed, won't be touched by spatial queries).
Hope this helps,
dan

How to change the geometry dynamicly
Hello,
I'm a newbie for java3d. I'm developing a degning tool with java3d, and need to change the geometry frequently therefore. However, the 3d result always shows the initial data only. Can someone gives me a hint about what's the problem, and how can I solve it?
Thank you very much!

Following is the relative codes:
private SimpleUniverse su;
private BranchGroup sceneBG;
private BoundingSphere bounds; // for environment nodes
public void paintComponent(Graphics g) {
setLayout(new BorderLayout());
GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
Canvas3D c = new Canvas3D(config);
add("Center", c);
c.addKeyListener(new KeyHandler());
su = new SimpleUniverse(c);
createSceneGraph();
initUserPosition(); // set user's viewpoint
orbitControls(c); // controls for moving the viewpoint
su.addBranchGraph(sceneBG);
public void createSceneGraph() {
sceneBG = new BranchGroup();
bounds = new BoundingSphere(new Point3d(0,0,0), BOUNDSIZE); // for environment nodes
lightScene(); // add the lights
addBackground(); // add the sky
sceneBG.addChild( new CheckerFloor(affine).getBG() ); // add the floor
addBuilding();
// sceneBG.compile(); // fix the scene
private void addBuilding(){
BranchGroup floorBG = new BranchGroup();
ArrayList groundArray = new ArrayList();
int num;
Point3f p1;
Vertex v1;
for (int n = 0; n < buildings.size(); n++) {
ground = buildings.get(n).getGround();
num = ground.getNumber();
for (int i = 0; i < num; i++) {
v1 = ground.getVertex(i);
p1 = new Point3f(v1.x,v1.z,v1.y);
groundArray.add(p1);
floorBG.addChild( new ColouredObj(groundArray, white) );
sceneBG.addChild(floorBG);
}note:
1. buildings is a global variable, which stores the geometry data. When the data is changed somewhere else, the 3D result does not change therefore.
2. ColouredObj is a class extented from Shape3D, which transfer the format from arrayList to quadArray, providing both gemetry and appearance.Ok, thank you for your reply.
In fact, it doesn't change anything on my OBJ objects : they always look strange (Java interpretation of faces more than 3 points is quite strange for me)... I will try to decompose each faces of my objects into triangles, but if you know an other easier method, it would be great !
So, I consider this topic solved, thank you for your help !!!

How to store numbers in a stack....
hello guys...i ve got the following assignment:
Write a Java program that reads and evaluates a fully parenthesised arithmetic expression. The
purpose of this program is to illustrate a fundamental use of stacks. Implement the stack using
Linked Lists as explained in your notes.
For e.g if a user enters the expression: (((6 + 9) / 3) * (6 � 4))
The result should be 10.
Your program should be properly documented and well structured. Specifications should be
clearly written in your logbook for all the methods, constructors, and classes that you implement
in the following format:
Class / Method/ Constructor name explaining what it does
Parameters
Preconditions
Postconditions
Throws
Now, i ve come up with the following code:
import java.util.EmptyStackException;
class StackNode {
private static Object data;
private StackNode link;
private static StackNode head;
private int totalnodes;
// the constructors
public StackNode(Object obj, StackNode lk)
data = obj;
link = lk;
public StackNode()
head = null;
totalnodes = 0;
// the push method
public void push(Object obj)
head = new StackNode(obj, head);
totalnodes++;
// the pop method
public Object pop()
Object answer;
if(head == null)
throw new EmptyStackException();
answer = head.getData();
head = head.getLink();
totalnodes--;
return answer;
// the isEmpty method
public boolean isEmpty()
return (head == null);
// get data
public Object getData()
return data;
// get link
public StackNode getLink()
return link;
// size or length method
public int size()
return totalnodes;
public static void main (String args [])
int i;
StackNode number = new StackNode();
StackNode operator = new StackNode();
head = new StackNode(data, head);
number.push(new Integer(9));
number.push(new Integer(6));
operator.push(new Character('+'));
and i dont know how to store numbers into the stack and how to use the operations such as addition substraction division and multiply...
any ideas how to do that??
cheers....This doesn't use a stack but the concept is the same:

How to store multiple files from SAp in to Application server?
Hi Guys,
Can anybody tell me how to store multiple files from SAP into Application server.in my application i have to get the data from SAP tables BSEG , BKPF , BSAK and BSIK that to daily i have to do.
Any Logic or Code for how to do is welcomed.
plz help me urgently.
Thanks,
GopiHi,
directories creates basis. If you have task to store data in application server you already should have information into which folder you have to do it. If you don't have this information because it is just for example training for next task then you can use your personal folder into which you have access. To get list of all available folders please look at attached code and form get_directories (you get the list of folders you see in transaction AL11). But don't forget: If you are using open dataset you have to have rights to access application folder!
Here you are code which I use to upload text files from local disc into application folder
Regards,
Karol

How to store España in database (in a column of a table)
Could you please tell me how to store España in database (in a column of a table).
regardsGenerally speaking you'll need a character set that can support the characters you require.
Here is a link to the supported character sets in 10.2.x.x:

How to store this value in date variable?
Hi sir,
i am having one query which is
select to_char(date '1900-01-01' + 1439/(24*60),'DD/MM/YYYY HH24:MI:ss')from dual;
when i am running this query i am getting this value: 01/01/1900 23:59:00
and this value i am inserting in one variable which has date datatype.
here i am storing like this:
v_nshiftmax := to_char(date '1900-01-01' + 1439/(24*60),'DD/MM/YYYY HH24:MI:SS');
while storing getting error: not a valid month
how to store it in this variable?
thanks964430 wrote:
why using TO_DATE (), to improve performance avoid function calling if you can do without it, just use v_nshiftmax := date '1900-01-01' + 1439/(24*60); remove TO_CHAR() function only, as you already converted it to date.Please prove to us that TO_DATE(...) is slower that using DATE '...'
Both are internal functions that take a string and turn it into a date. -

How to store the output of a analog to digital converter into an 2D array
Hi
I am doing my M.Tech Thesis in Image reconstruction and I am using labview for simulation and I want to know how to store the output of a analog to digital converter into an 2D labview array.nitinkajay wrote:

How exactly are you performing 'Analog to Digital'???
Grabbing image using camera OR performing data acquisition using DAQ card OR some other way????
I am not allergic to Kudos, in fact I love Kudos.

How to store multiple data in one aray at one go?
Hi i am creating a Recipe Cooking Book and i have got a recipe class, ingredient class, equipment class and jFORM GUI. the gui form will have a list and it will contain couple of equipments. the user should be able to select more than 1 equipments which would use the pass- by - value to the recipe class and it will be passed to equipment class.
The problem that encounter is that when i have to select multiple values from list, it should store all selected equipments to array.
This is where i am stuck as i don't know how to store couple of equipment at one creation.
This is my recipe constructor in recipe class
public Recipe(int aRecipeID, String aRecipeName, String aCountryofOrigin,
String aType, String aPreparationTime, String aCookingTime,
String aRecipeDescription, String aProcedure,
ClsEquipment[] aequipment, String aImage1, String aImage2,
String aImage3) {
Create(aRecipeID, aRecipeName, aCountryofOrigin, aType,
aPreparationTime, aCookingTime, aRecipeDescription, aProcedure,
aequipment, aImage1, aImage2, aImage3);
public void Create(int aRecipeID, String aRecipeName,
String aCountryofOrigin, String aType,
String aPreparationTime, String aCookingTime,
String aRecipeDescription, String aProcedure,
ClsEquipment[] aequipment, String aImage1, String aImage2,
String aImage3) {
RecipeID = aRecipeID;
RecipeName = aRecipeName;
CountryofOrigin = aCountryofOrigin;
Type = aType;
PreparationTime = aPreparationTime;
CookingTime = aCookingTime;
RecipeDescription = aRecipeDescription;
Procedure = aProcedure;
*equipment[j] = aequipment[k];*
Image1 = aImage1;
Image2 = aImage2;
Image3 = aImage3;
this is The command that i have in Jform gui
public void jRcreateButton_actionPerformed(ActionEvent e) {
int i=0;
myRecipe.Create(Integer.parseInt(jRidTextField.getText()),jRnameTextField.getText(),jRcountryTextField.getText(),jRtypeTextField.getText(),jRptimeTextField.getText(),jRctimeTextField.getText(),jRdescriptionTextArea.getText(), jRprocedureTextArea.getText(),new ClsEquipment(jAEequipmentList.getSelectedValues()),jRimage1TextField.getText(),jRimage2TextField.getText(),jRimage3TextField.getText());
Let me conclude what i am trying to do. Basically i want the user to select more than 1 equipments from the List and the user should also input other recipe data. once this is done, the should click on create.
when creating one recipe, u need more than 1 equipment so that created recipe should store selected equipments, which i will later on retrieve and display on screen.
can u please guide me where i am goin wrong and how i could fix it.
thank you in advance
Edited by: JAVABABY on Feb 18, 2008 8:40 AM*equipment[j] = aequipment[k];*JList's getSelectedValues() method returns an array of Objects, so if you wanted to store it into another Object[] reference, you'd just use
equipment = aequipment;But, you are storing it as an Equipment array, so you'll need to loop over the Object array and cast each element to an Equipment reference, and store it into the Equipment array. Something like this:
equipment = new Equipment[aequipment.length];
for (each element x in aequipment) {
equipment[x] = (Equipment)aequipment[x];

How to store movies & TV shows in a different location
Hi there!
I've seen many of you asking (unfortunatelly with no clear answer) how to store movies & TV shows into another location away from the iTunes Music folder. This idea is to store videos on an AirDisk drive and keep music on the MacBook for example!
I've been trying to do so in the past few days but some pb have occured...
- it is possible to replace the Movies folder by an alias pointing to a Movies folder in the AirDisk drive: existing movies will be playable in iTunes.... the problem is that when I try to add new movies iTunes do not store them into the Movies folder on the AirDisk but in the local music folder (very strange as it is a video file!).
Has anyone succeeded in using such mechanisms?!
Many thanks for your answers!

I've got a couple of movies and tv shows that I've deleted from my purchase list on itunes as well as my download file on my computer but they are still on my itunes in the cloud does anyone know how I can delete these?
You cannot delete them from iCloud.
They are purchased and will always be available in iTunes in iCloud for you to download again if you wish. -
How to store the value of sum of group in Crystal Report at the runtime!
Hello all,
I creates a Formula Field that hold the value of Sum of Group in Crystal Report. I would like to know how to store it in a variable and pass it to store procedure. Is it an option in Crystal report to do it. I knew that Crystal Report can cache the report for sharing. My detailed issue as following:
- Created a Formula Field named TOTAL AMOUNT that calculated the complex expression. This TOTAL AMOUNT is dynamic based on group and variables.
- I would like to store that value from TOTAL AMOUNT and pass it to the stored procedure parameter IN.
Any helps are much appreciated. Thanks.I doubt that this is possible since it would only calculate this value once the report has data. This sounds more like a report design question that should be asked over [here|SAP Crystal Reports;

Help! Can't figure out how to store the same photo in different events
I know that this is just a user error problem, but I can't figure out how to store multiple versions of the same photo in different events. For example, I use Aperture as my main photo library, so I have a big folder set-up by year and then by events within those years to organize and maintain my library. I'm currently working on a project where I would like to pull out certain pictures for other uses. I tried creating new events and then moving the pictures to those events (like I would have in iPhoto) expecting for a new version of the picture to be deposited in the new event. That didn't work - it moved the picture out of my "main library" folder and as far as I can see it now only exists in the new event. Next, I tried creating "new versions" of the pictures I wanted to move and then just selecting those and moving them. In one folder I selected three photos, clicked "New Versions", then in the browser display I could see two of each picture (for a total of six), I selected ONE of each photo and moved those three to the new event. At which point all six disappear from the "main library" and end up in my new event. I don't understand why that happens. Currently the only way I've been able to do what I need to do is by using the flag field, but as far as I can tell there is only one of those - it's on or off that is really not serving my purpose. What do I need to do???
Like Jim said, you most likely want Albums for what you describe. Albums simply consist of "pointers" to a single compilation of image data. Albums can be created and deleted at will, because they are just pointers; an important concept.
Also learn to use Keywords - and unlearn "folder" organization, which is not the way digital asset management works. The power of Albums and Keywords is huge once we lose the film-think of folders organization.

How to store the contents of a file
Hi,
I'm using forms6i and database 10g.
Through forms if a user selects a filename , and clicks a button or something,
the contents of the file should be saved in the database.
The file can be of any type, like .doc,.pdf,.xml,.html etc...
and the contents filed will be of type varchar
Please help me do this..
ThanksDo you really want to save the "Content" of a file or the file itself? If you try to save the contents of a .doc or .pdf in a column with a VARCHAR2 datatype, you are going to corrupt the contents of the file since these file types have binary data in them as well as text. I think you would have greater success storing the actual file in a BLOB column.
Here are a few Oracle Support documents that discuss how to store and retrieve files stored as BLOBs in the database.
Doc ID: 168277.1 - How to Upload Binary Documents Back to Database BLOB Column from Forms
Doc ID: 330146.1 - How to write BLOBs Stored Inside the Database Out to Files.
Hope this helps,
