How to write values to an array and call these to produce an xy graph

Hi, Hopefully someone can help. I have attahced my VI.
I am happy with how to write data to a file, which I have already done. The next thing I want to do, is write the pressure and acoustic values to an array for the duration of my testing (Testing is when the log switch is on). Once I switch the log button on my front panel off, I want to be able to call another VI which will display an XY graph of the Pressure and acoustics Vs Time. This will be populated from the array I create. Can anyone please help.
Thanks in advance.

Since you are acquiring one point at a time, use a shift register and build an array of points , bundle it and display on XY graph
As shown in attached VI

Well you are doing almost everything wrong that could be done wrong.
Here is code that works to insert data into your table (the procedure isn't even needed).
declare
p_sl_num NUMBER := 1001;
p_description VARCHAR2(50) := 'Testing Val1';
inval1 test_type1 := test_type1();
inval2 test_type2 := test_type2();
begin
inval1.extend();
inval1(1) := test_object1('testx1', 'testx2', 'testx3');
inval2.extend();
inval2(1) := test_object2('testy1', 'testy2', 'testy3');
INSERT INTO test_object_tpe
sl_num,
description,
main_val1,
main_val2
VALUES
(p_sl_num, p_description, inval1, inval2);
commit;
end;
/See Example 5-15 Referencing a Nested Table Element in Chap 5 Using PL/SQL Collections and Records in the PL/SQL doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/collections.htm#CJABEBEA
1. You don't even need the procedure since all it does is a simple INSERT into the table which you can do directly (see my code above)
inval1(1).val1 := 'testx1';There is no element one (1) of 'inval1' since you haven't created any elements yet. You need to EXTEND the collection to add an element
inval1.extend();And then there is an empty element but 'inval1' is a container for objects of type 'test_object1' not for scalars like 'val1', 'val2', and 'val3'.
So you can't do
inval1(1).val1 := 'testx1';You have to create an instance of 'test_object1'
inval1(1) := test_object1('testx1', 'testx2', 'testx3');And so on for the other collection
You don't need the procedure (as my sample code shows) but once you populate the variables properly it will work.

Last One I Promise! Inserting A Value In An Array And Shifting TheRest Over

Last question I have, I need to know the theory behind inserting a value into an array and shifting the rest over.. I have somewhat of an idea and that is this:
Obviously I need to use a for loop, and a temp value to hold each value until it shifts then move on to the next value? Oh and increase the size of the array by one? I'm having trouble making sense of it..
lets say we have the same array as from before
          int[] aRay = new int[5];
          aRay[0] = 1;
          aRay[1] = 9;
          aRay[2] = 3;
          aRay[3] = 4;
aRay[4] = 11;
and we want to add... lets say the element 5 into the index spot of 2 is and shift 2 to 3 and 3 to 4 and 4 to 5.
for ( int i = 0; i < aRay.length; i++) // this will move along each element of the array (so I know I need this for sure)
Am I on the right track? thanks all

Once I get that, the rest will be cake
int[] aRay = new int[5];

Do I just make this a 6? or is that not the right way.. :/You can't change array sizes dynamically. You will have to make a new array of the appropriate size and copy into it. You could use copyOf: http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#copyOf(int[],%20int)
I hope this is purely an academic exercise, because there's no reason to do this.

How to split the blob byte array and insert in oracle

how to split the blob byte array and insert in oracle
I am having a string which is of more than lenght 4000 so i am using BLOB datatype as input to get the string.
need to split the blob in oracle and store in the different column
The string is of bytearray i need to strore it in each column based on the byte array.

this will be my input i need to split the above and store it in different columns in a table.
for spliting say
Column1 -1 byte
Column2-3 byte
Column3-5 byte
ColumnN-5 byte
Table will have corresponding data type
Column1 - number(10,2)
Column2 - Float
Column3 - Float
ColumnN-Float
here Column2 datatype is float but it will always have 3 byte information.
where as Column3 datatype is also float but it will always have 5 byte information.
Say N is Column 120

SInce i am using Netbeans IDE 5.5
and there is easy to do swing programming using this IDE
now i am confused using JTable and JList box
since i used method Insert in AWT
but how to add values in LIST BOX ( JList )
ex.
JList list = new JList( );

here it ask for component so what should i write here..
when i write here this, gives error.
what to do to insert string or vector or object in JList
and to enter value in JTable
THanks

hi Ghanshyam,
i am also new to swing i was just wondering are you using the swing palette to create your interface
by the look of the code
JList list = new JList( );
list.add(mystringvalue, ? );you may not be because every JList is put in a JScrollPane
but if you do want to do it through the palette there is an option in properties - model which you can uses to add in values.
and if your looking to get info. from a database look up
AbstractListModel &
AbstractTableModel
the is a lot of info on the internet (example net beans CarTableModel) is a
good start off
happy hunting.

Hello everyone,
I need help in inserting values into an array of class, which i have read from a file.
Length of the array is 5. I should insert values one by one into that array.

How to get value from option box and submit accordingly

Sorry for posting my question. I have been trying to edit message and repost it and not successful. Hence I am reposting my question. Please let me know.
I am right now exploring JSF for presentation layer. I am designing a form with <h:outputLabel..> and <h:inputText...> for the user to input his value. I also have a radio button as below. <h:outputLabel..>
<h:inputText...>
<h:selectOneRadio id="libraryList" >
                            <f:selectItems value="#{libraryList}"/>
                        </h:selectOneRadio>And I have included the following piece of code in faces-config.xml as below.
<managed-bean>
        <managed-bean-name>libraryList</managed-bean-name>
        <managed-bean-class>java.util.HashMap</managed-bean-class>
        <managed-bean-scope>application</managed-bean-scope>
        <map-entries>
            <map-entry>
                <key>Pass</key>
                <value>Pass</value>
            </map-entry>
            <map-entry>
                <key>Fail</key>
                <value>Fail</value>
            </map-entry>
        </map-entries>
    </managed-bean>Hence I get two option box as Pass and Fail.
I am also bit aware of navigation rules of JSF. Now I want the user to take to the step 2 if he chooses the option Pass and if the user chooses Fail, then I want to reset the values of the above form and display the same form.
I have not done any Java part of the application yet as I am a newbee and hence started doing JSP pages and config-faces.xml part. Please let me know how to proceed further.

Create a bean, bind the value to the bean, let the action method return that value and add navigation-case entries for those outcomes.

How to write the code for IMPORT and export in Field exit

Hi,
Using the FB01 tcode with condition as document type (ZF) and company code
i want to substitute values should come in the next screen.
i am passin the document type and the company code in the FB01 initial screen (100) and added field exit for Cost centre.
if the Doc type ZF and company code is 0245 then the field exit shoul trigger and give the defaul cost centre value if it contain any cost centre valu it over write the existing if it is empty i will write the defauls cost centre value.
Thanks & Regards,
Nelsons......

Hi,
As i have understood, if ur doc type is ZF and company code is 0245, then you want to pass the value to cost centre field in next screen.
You can use program RSMODPRF. here enter the data element of cost centre field and assign the screen no and program name (for FI docs prg name would be SAPMF05A).
After assigning program and screen no , Create the function module where u have to write an 'if' statement for assigning value to cost centre (i.e export field in FM)
the values for company code and document type can be fetched from their respective parameter ids i.e. BUK and BAR.

How to create a grid with arrays and booleans?

As part of a bigger project, I'm trying to create a sub-VI which will allow me to move a "cursor" in a 3x3 array.
There should be 2 boolean inputs, one for moving down in the array, and the other for moving to the right. Once the edge of the array has been reached, the "cursor" will start back from the beginning.
I have a vague idea of a 2 dimensional array with LED's. Once "down" has been pressed, the LED corresponding to (0,0) will turn off, turning (0,1) on. Same goes for the "right" button. When "down" is pressed at (0,2), the LED should turn off, and LED (0,0) should turn on.
I'm sure it has something to do with initializing arrays, but i can't seem to find the right way to do it.
Any kind of assistance is much appreciated. Thanks!

How to sum all bytes in array and remove carry/overflow ?

Hi.. everybody !!
I want to make bitwise operation in Labview. By the way,sum all bytes in array and remove the carry/overflow.
Anybody has an idea about that ?
Thanks

If your array is an array of U8 type numerics, then all you have to do is sum the elements. This will return a U8. No carries. Sounds like what you're looking for.

Testcase, how to split up an xml message and call a BPEL process.

Another question.
Considering the following XML message.
<?xml version="1.0" encoding="UTF-8"?>
<rows>
<row>
<id>10</id>
<naam>A</naam>
</row>
<row>
<id>20</id>
<naam>B</naam>
</row>
</rows>
An input message can consist of 1 to about 20000 <row></row> elements. I would like to split up this message into individual <row></row> and call a BPEL process for further processing.
I've tried to use the file adapters feature "Files contain Multiple Messages" Publish Messages in batches of.." This did not work. ( root element expected exceptions ).
I've also tried to invoke an extra async routing service with a mapping which removes the root element. This also doesn't work as it leaves the following ( incorrect ) xml message at the end.
<row>
<id>10</id>
<naam>A</naam>
</row>
<row>
<id>20</id>
<naam>B</naam>
</row>
Which is logical considering how an XSL transformation works.
Is there any way to achieve this?
Any help is appreciated!

You shoul create a while loop, that loops through XML payload for each row. Than you can process each individual row. See also example:
