Creating polygons with an array of doubles instead of ints
Hi,
I want to create a polygon using:
Polygon u = new Polygon(xPoints, yPoints, numTs);
my problem is that my x & y points are stored in double arrays not ints. Is there a way to create a polygon using double arrays instead of ints?
cheers,
elmicko
or cast them as int. imaginr posX, posY, width and height are doubles.
Rectangle rect = new Rectangle( (int)posX, (int)posY, (int)width,(int)height );or, with an array of doubles:
Rectangle rect = new Rectangle( (int)array[0], (int)array[1], (int)array[2],(int)array[3] );

DrawLine using double instead of int
I'm trying to use the java.awt to draw a line but I would like to use doubles instead of ints.
the normal way would be to use drawline(int x, int y , int x2 , int y2);
but i cant find a way to drawline( double x, double y, double x2, double y2)
any idea's?
Some more detail about this is I�m trying to create a package to draw a graph and my points are in double (and I would like them to stay that way) is there a way?
Many Thanks, Johnif you want to keep it in doubles you could use Line2D.Double from the java.awt.geom package. Then instead of a call to drawLine(int, int, int, int) call draw(line2D) passing in the line2D. As it implements the shape interface it will know what to do. Note to do this call you'll have to cast the Graphics object to a Graphics2D.
Hope this helps

Hello, i am trying to figure out how to create pagination with an array. I have done it before with a query but i can't seem to figure out how to do this with an array. Can someone please help me out with this?
I meant to say, its an array result set. I'm testing it with an array of 9 elements, and it knows that it should be 2 pages with 5 records each, but its expecting 10 results and i can't get it to work with 9.

Hello.
During developing Domain Index for Oracle 11.2.0.1.0 (problem also appears in 12с) i was faced with misunderstanding of parameter types of function
ODCIIndexInsert in case of creating indextype WITH ARRAY DML option
According to Oracle documentation
http://docs.oracle.com/cd/E11882_01/appdev.112/e10765/ext_idx_ref.htm#i76892
In case of WITH ARRAY DML option Oracle will invoke ODCIIndexInsert with following signature
FUNCTION ODCIIndexInsert(
ia ODCIIndexInfo,
ridlist ODCIRidList,
newvallist varray_of_column_type,
env ODCIEnv)
RETURN NUMBER
In my case indexed column has datatype NUMBER so i defined varray_of_column_type as SYS.ODCINumberList
STATIC FUNCTION ODCIIndexInsert(ia in sys.ODCIIndexInfo, ridlist in sys.ODCIRidList, newvallist in sys.ODCINumberList, env in SYS.ODCIEnv) RETURN NUMBER
Indextype was created as
CREATE INDEXTYPE test_index_type
FOR
test_eq(number, number)
USING index_methods
WITH ARRAY DML(number, sys.ODCINumberList)
WITH LOCAL RANGE PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
or
CREATE INDEXTYPE test_index_type
FOR
test_eq(number, number)
USING index_methods
WITH ARRAY DML
WITH LOCAL RANGE PARTITION
WITH SYSTEM MANAGED STORAGE TABLES;
(problem occurs in all cases)
CREATE TABLE test_table (id NUMBER (19,0));
CREATE INDEX test_index ON test_table(id) INDEXTYPE IS test_index_type;
When attempting to insert data in the table
insert into test_table values (1);
oracle raise exception
Error starting at line 53 in command:
insert into test_table values (1)
Error at Command Line:53 Column:1
Error report:
SQL Error: ORA-29925: cannot execute SCOTT.INDEX_METHODS.ODCIINDEXINSERT
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIINDEXINSERT'
ORA-06553: PLS-306: wrong number or types of arguments in call to 'ODCIINDEXINSERT'
29925. 00000 - "cannot execute %s"
*Cause: The specified function does not exist or does not have an
appropriate signature.
*Action: Implement the function with the appropriate signature.
So my question is.
Is it normal behavior of oracle (according to documentation)?
What is correct signature of ODCIIndexInsert function in case of INDEXTYPE creation with 'WITH ARRAY DML' option and fact that indexed column has NUMBER datatype?
By the way if i define indextype without 'WITH ARRAY DML' option signature is clear, and working. But this approach doesn't satisfies our performance needs.
Also if i define index type with option 'WITH ARRAY DML WITHOUT COLUMN DATA' and use signature
static function ODCIIndexInsert(ia sys.odciindexinfo, ridlist sys.odciridlist, env sys.ODCIEnv) return number
Everything works too. But this approach doesn't satisfies our business needs.
Is it a way to define ODCIIndexInsert parameter types (in case of indexing number column) so that batch inserting works according to documentation ?

Reading arrays of double from S7 with OPC & Datasocket
Hi friends:
We are developing an application with a S7-315-2DP PLC and a PC with a PCI1500PFB. We use the OPC server from Applicom. We read the data very quickly with the datasocket (arrays of boolean, arrays of doubles ...and so on, and a very big amount of data over 100 ms) but when we try to write arrays datasocket faield and we have to write item on item and the speed decrease. For intance, if we try to write doubles ( 50 items) the refresh period is over 5 seconds ( some times more since we launch the data and we read the same data on the PC). Perhaps we failed configuring the OPC but there isn´t many things to configure, perhaps the problem is the board configuration .. I don´t know.
We
try to find some examples that write an array of doubles on one time but..
Thank you for yours answers.
JaviHi Javi,
I'm not aware of any known issues writing to the Applicom OPC server. In LabVIEW there isn't anything special you need to configure to be able to write arrays of doubles through DataSocket. You can test this by using the DataSocket Server Manager, make a new member that is an array of doubles, and try reading and writing to that member. You may also want to check to make sure the data member the OPC server is expecting is an arry of doubles and not an array of singles or integers. -
Create dll with arrays and call it
I am trying to create dll with labview in order to pass a 2d array to the main program. The problem is that I don't really know how to create the function to call it (I don't know much about pointers)
The function I have created to call the dll is void Untitled1(TD1Hdl *Array1) which is suposse to return the array created on it.
For example, in the program attached, how should I do to pass the array to another program using dlls?
Thanks a lot,
Juanlu

Untitled 1.vi 7 KBThe code you've provided doesn't do anything (just a control wired to an indicator) so I'm not sure what you're asking here.
If I understand correctly, you want to build a DLL from your LabVIEW VI. From what language will you call that DLL? There is no standard way to pass a 2-D array. If you can convert to a 1-D array, you can use a simple pointer. With a 2-D array, you're stuck with LabVIEW's array representation (the TD1Hdl type), which means that whatever code calls that function will need to understand the LabVIEW data type and how to manipulate it. -
Error ORA-01426: numeric overflow when Creating table with double data type
Hi,
I am using ODP.NET to create a table with data from SQL to Oracle. The problem is with double data type fields that is equivalent to FLOAT(49) in Oracle. My syntax is:

Creating a Two Dimensional Array in Xcode and populating it with a values f
Whats the easiest way to declare a two dimensional array in Xcode. I am reading an matrix of numbers from a text file from a website and want to take the data and place it into a 3x3 matrix.
Once I read the URL into a string, I create an NSArray and use the componentsSeparatedByString method to strip of the carriage return line feed and create each individual row. I then get the count of the number of lines in the new array to get the individual values at each row. This will give mw an array with a string of characters, not a row of three individual values. I just need to be able to take these values and create a two dimensional array.I'm afraid you are in the wrong place. Look here for the last two forums on programming. However, XCode support is mostly found at developer.apple.com. You can access their forums by registering. Registration is free.

Is it possible to create a 1 D array with the "build array VI"? when receiving random number
Hello all,
Is it possible to create a 1 D array with the "build array VI" when receiving random number?
I am receiving random data and the build array VI always create a 2D array which might cause some problem if you want to compute certain type of operation after.
Any example will be welcomed.
Thank you,
IsraelHello Lynn and Yamaeda
First I want to Thank you Lynn for your linguistic contribution indeed "Build Array" is a primitive and not VI, thank you for the education. In reality what I am doing is simple.
I have two arrays of complex elements Array1 and Array2.
Array1 conains the complex elements ""(a0+ib0) ; (a1+ib1) ;...(an+ibn) ;
Array2 conains the complex elements ""(c0+id0) ; (c1+id1) ;...(cn+idn)
What I want to do is the multiplication of the first array by the conjugate of the second array element.
Array1*(Conjugate Array 2)" for the first element the results is "(a0.C0-b0.d0) + i(b0c0-a0d0)" and the etc...
and then taking the square root ([(a0.C0-b0.d0) power of 2]) + [(b0c0-a0d0) power of 2])
I was wondering if there were some dedicate primitive that could solve the computation above which is the cross correlation in Frequency domain.
Thank you very much.

Labview Calling DLL with 2D array input and output
Hi all，
I have to call a dll which a 2D double array as an input and also a 2D double array as an output.The dll is made by me and written in c language , I need it to work efficiently.
If i define the program in labview like this
The 2 2Darrays sent into CLN were "Array data pointer",then how to define the function in c laguage? just like -----int myfunction (Parameter1,Parameter2,Parameter3,Parameter4)
If the function in the dll is defined like this int myfunction (double **A, int sx,int sy ,double **B,int ix,int iy),then what will the program in labview will be ?
sx ,sy ix ,iy are the array's size.ylongwu wrote:

Your proposed prototype double ** seems to indicate that you want an array of pointers to the rows of the array. That is not how LabVIEW stores multidimensional arrays (nor how this is usually done in C for such arrays).
LabVIEW and most C libraries threat multi dimensional array as one single block of memory where the rows are located one after the other. So as DFGray has already pointed out you should use double * instead as datatype or since you create the DLL yourself and if it doesn't need to be compatible with other environments than LabVIEW change that altogether into:
typedef struct {
int32 dimSize1;
int32 dimSize2;
double elm[1];

int myfunction (2DDblArrHdl A, 2DDblArrHdl B);
then change the Call Library Node parameters for the arrays to pass the array as Data Handle (the native LabVIEW datatype) and leave away the extra dimensions since they are already inside the handle structure.
Last but not least if you want to be very fancy you can even use NumericArrayResize() on the output handle to resize it to the correct size before filling in your information and leave away the Initialize Array function on the LabVIEW diagram.

Extrude 3D polygons with multiple rings in Oracle spatial
In this thread Extrude 3D polygons in Oracle spatial Baris provided a sample script to extrude a polygon with one ring into a 3D solid.
How do I extrude a polygon with multiple rings?
Given this polygon

, I tried to create a solid as follows:

If the heights and ground heights are all the same in your sdo_number_arrays (as in this case), then you can just specify one number in each array instead of specifying a height/ground height for each vertex.Ok, I see what you mean. This works when I use just the outer ring.

Volume: 11839.18887702For the purposes of what I'm doing now, I think I'll just use the outer ring to create my solids, but it would be useful if SDO_UTIL.EXTRUDE works on polygons with multiple rings (maybe it does, I'm probably doing something wrong...). -
Trouble creating and populating an array of objects.
I'm trying to create/populate an array of objects with consisting of a {string, double, integer}, and am having trouble getting this theory to work in Java. Any assistance provided would be greatly appreciated. Following are the two small progs:
public class HairSalon
{ private String svcDesc; private double price; private int minutes;
//Create a constructor to initialize data members
HairSalon( )
svcDesc = " "; price = 0.00; minutes = 0;
//Create a constructor to receive data
HairSalon(String s, double p, int m)
svcDesc = s; price = p; minutes = m;
//Create methods to get the data members
public String getSvcDesc( )
return svcDesc;
public double getPrice( )
return price;
public int getMinutes( )
return minutes;

sal[0] = new SortSalon("Cut"; 10.00, 10);
sal[1] = new SortSalon("Shampoo", 5.00, 5); sal[2] = new SortSalon("Sytle", 20.00, 20);
sal[3] = new SortSalon("Manicure", 15.00, 15);

That did do the trick! Thanks for the assistance. I was able to compile and run the program after adding my sorting routine. Do you happen to see anything I can do to clean it up further, or does it look ok? Thanks again,

ThanksHi,
it seems you forgot the curly braces in the if-else statement:
if (array1Size >= array1.length){
//Make a new array doubling the values od the integers
int array2 [] = new int [2 * array1.length]; // 10 integers
//Copying integers
System.arrayCopy (array1, 0, array2, 0, array1.length);
//Make old reference point to new array
array1 = array2;

anotherArraySize++;
System.out.print ("Another number? Enter Y or N: ");
goon = EasyIn.getChar();
} while(goon = = 'y' | goon = = 'Y');

I need to display an array of doubles on a table and I am loosing my percision
Hello,
I need to display an array of doubles on a table but I am losing my decimal precision. I am converting the array to a string in order to display it on the table with a number to decimal function. This is where I lose my precision since that control converts the double into an integer and then into the string. What control do I need to use instead of that in order to preserve my decimal precision all the way to the table? I have attached my VI. Thanks in advance!
