Insert 1d array into 2d array step by step by clicking a button

Hello. I work on a project, whicht helps me to analyse graphs. I want to export values to only one spreadsheet For each measurement the values will be exported to an 1D array. The analysis of the graph works by moving cursor lines. Now what I want to do is to add 1D array of each measurement to an 2D array step by step by pressing a button, so that I’m able to get a table of values of the whole graph. With every button click, a new row (n+1) with the new values of the measurement schould be created in the 2d array. The first row schould have index 0. If there is no measurement anymore, the content of trhe 2D array should be stored to a text file.
Please help me out!!!
Thx.

Most likely, your modification is stuck at the event structure. Try to add an empty timeout event so the event structure does not block the rest of the code.
To get e.g. the subarray between two cursors, you could do something like in the attached modification (of course it is a bit inefficient, because it does it over and over again while the loop is running, even if the cursors do not change).
What is your LabVIEW version? LabVIEW 8.0 has events that are triggered by movements of the graph cursors. Quite useful!

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

Hihow to insert 2 elements into 2D array?

Hi I had a hard time figuring out how to insert 2 elements into 2D arrays.
I tried using replace and insert array functions but it does not work right way.
I am using LV7.1. See the pic below.
How do I insert elements in that way?
Pls advise
Clement

Well, "replace array subset" is not the right tool, because it keeps the size of the array constant. Insert into array only works for entire rows or columns.
You need a hybrid approach, because you want to insert elements at the beginning of column 1 while padding the remaining columns to the new lenght of column 1. This won't be efficient but there are plenty of ways to do that (here is one example with DBL arrays, should work equally well for string arrays as in your case).
How much flexibility do you need? Is it always at the beginning of the first column? Are the arrays huge (=is performance an issue)? Is this a rare operations or do you constantly need to do this (e.g. inside a loop).
In any case this seems like a rather arbitrary and somewhat silly operation. What is the practical purpose?

How to insert an array of number into access database?

How can I insert an array of numbers(double) into an access database and later read them back to an array I labview. I don't have the Database Connectivity toolset. I would prefer using the LABSQL or other free solution. Any idea on how to solve this. I have tried LABSQL and SQL commands, but when I do that I have to convert the number to a string and then make a SQL-command string. Is there a way where I don't have to convert the number into a string?

Hello,
I am not familiar with LABSQL and we do not do any support on that particular product. However I still want to give you some information on how to proceed. You can either store the array to binary format and by doing this you can save an entire array to one single element of the database. The other alternative is of course to save one-to-one in other words one element of the array in one element in the database.
More info can be found here:
http://digital.ni.com/public.nsf/websearch/3FE68BBDA95E845986256DB4006A22C0?OpenDocument
Have you checked MSDN for information regarding this? You might be able to find useful SQL code there to use.

Inserting a record into an array

I have an applet that pops up different frames when you click on a menu item. On my add a record frame I have a number of textfields and an add button. When the button is clicked it is supposed to insert the record into my array of objects that only can have 3 records. When the button is clicked however I get a null pointer exception. I want to add the record in order based on the employee number, so first I want to check to see if the first spot of the array is null and add the record in the first spot if it is. If it isn't I want to check the employee numbers and insert the the record in the correct place and make sure the array isn't full. Can someone help me out 1. Why the nullpointer exception. 2. I am not sure if my logic is correct. Below is the Code. Thanks!!
public void insertRecord()
if (MyEmpArray[0] == null )
addRec(0);
else
for(int index =0; index <3; index++)
if(intEmpNumber < MyEmpArray[index].intEmpNumber && MyEmpArray[3] != null )
addRec(index);
else
lblErrorMessage.setText("Array is full");
public void addRec(int index)
MyEmpArray[index].setValues(intEmpNumber, strFirstName, strLastName, strHomePhone,
strStreet, strCity, strState, strZip, strCountry, strWorkStreet,
strWorkCity, strWorkState, strWorkZip, strWorkCountry, strWorkPhoneNum,
fltNumHours, fltHourlyWage, intI, intJ, intK);
lblErrorMessage.setText("");
txaReport.setText("");
ClearFields();
}

for(int index =0; index <3; index++)
An array with an index from 0 to 3, contains 4 records: you should replace it with
for(int index =0; index <2; index++)
The check-logic is good enough, but there are two minor "bugs":
1) even If the array is full, the for cycle will uselessly check all the records
2) if a the employee number of intEmpNumber is > thanMyEmpArray[index].intEmpNumber the program will show up "Array is full" even if the array isn't full.
So, I suggest to add more code to make distinction between the two cases:
for(int index =0; index <3; index++)
if(MyEmpArray[3] != null ) // check if there is space to add a record
if (intEmpNumber < MyEmpArray[index].intEmpNumber) //check if the position is right
addRec(index);
else
lblErrorMessage.setText("Array is full");
break; // exit the for cicle as the array is full
I don't know what you are programming, but I ask you: "If the new intEmpNumber is < than the intEmpNumber of an already-full-array shouldn't be the new record inserted, discarding the last one?"
I don't know if addRec works, I'm don't know applets, buttons..:)
Sorry for my bad english...I hope this post will help you anyway :)

How to insert an object into an object array

I have an array of objects and im trying to insert an object into the array at position zero. Does anyone know what method I can use for this?

Hey,
Are u using a normal array or an array list ?
For instance if you are using a normal array and you wnat to store an object of classX it should be something like this:
myArray[0] = new classX(vlaue1, Value2, Value3);this will only work if you have a default constructer for the objects.
I am posting under correction here but this is the basic idea.
Hope it helps :-)

How to correct copy/append/insert a array in BPEL

BPEL
Hi @ all,
I have a message type I'd like to iterate through and extract values from array (1).
Then place into another array (2):
TestOutputVariable(Array (1)):
<roottest>
<AAA>
<BBB>result1.1</BBB>
<BBB>result1.2</BBB>
<testname>test1</testname>
</AAA>
<AAA>
<BBB>result2.1</BBB>
<BBB>result2.2</BBB>
<testname>test2</testname>
</AAA>
</roottest>
ReportInputVariable(Array(2)):
<rootreport>
<AAA>
<name/>
</AAA>
</rootreport>
for example ReportInputVariable must be like:
<rootreport>
<AAA>
<name>test1
</AAA>
<AAA>
<name>test2
</AAA>
</rootreport>

Ok let's see (staying in english is allright I hope... eventhough my is getting really bad).
As I said I only can extract the data until now, haven't tried to write it to an array. In addition don't copy the code I give here because it's only to give you an hint. But the JDeveloper is a really cool tool to "click" the right expressions together...
So the trick is to "build" the xpath to access the arrayfield you want to fetch. Therefore at first you need an counter:
<assign><copy><from expression="1"><to variable="counter"></copy></assign>
Now you're going to build your xpath:
<copy><from expression="concat('/roottest/AAA[',bpws:getVariableData('counter'),']')"/>
<to variable="xpathPosition"/>
</copy>
Now you an xPath which is pointing to the child elements of your first node <AAA>. You use these expression now for the copy process:
<copy>
<from expression="bpws:getVariableData(???, ???, concat(bpws:getVariableData('xpathPosition'),'/testname'))"/>
<to variable="output"/>
</copy>
Notice that ??? stands for Variable and Part name - still fighting with the syntax. The main point is that concat gives you the xpath expression to the array field you want (for counter = 1 eg. "/roottest/AAA[1]/testname") - that's it.
To assign the value to an array - sorry, haven't tried it but the link I posted seemed good. The problem is that in order to insert the data into an array you have to append a new element into the array and therefore use one of the extended functions (=bpelx).

Insert String array as label content in datagrid row through radio button C# wpf?

I have written some code for inserting label at runtime having its content set to a string array and then insert that label into a datagrid row . All of this will initiate when certain radiobuttons are checked. code is working perfectly fine. But i need

@Usamakhan1990,
Use usercontrol with label and checkbox is reasonable for a datagrid control if you don't want to have too much code for those radio buttons. So I agree with andy here with that usercontrol.
So is it required that your radiobutton should be outside the datagrid?
Anyway, I think you already know that you can bind data to columns yourself. So please check the following thread:
http://stackoverflow.com/questions/22922533/how-do-i-automagically-bind-a-string-array-to-a-wpf-datagrid
<DataGrid Name="_dataGrid" Grid.Row="0" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Column 1" Binding="{Binding [0]}"/>
<DataGridTextColumn Header="Column 2" Binding="{Binding [1]}"/>
</DataGrid.Columns>
</DataGrid>
Or define the columns from code, in case you have dynamic number of columns, for example :
string[][] array = fs.CSVToStringArray();
for (int i = 0; i < array[0].Length; i++)
var col = new DataGridTextColumn();
col.Header = "Column " + i;
col.Binding = new Binding(string.Format("[{0}]", i));
_dataGrid.Columns.Add(col);
this.ExternalData._dataGrid.ItemsSource = array;
And for Radio button part, please see here:

Inserting an array

hi all,
I found the attached VI on the ni homepage. It would perfectly meet my requirements
(filling a database with an array with the possibility to define the number of cols
to be inserted). But i couldn't get it work. I always get the error message 'the number
of columns does not equal the number of parameters'.
Does anyone see what I'm doing wrong?
thank you very much

Hi Simon,
you want to insert your array in the database in one step, right?
The Bitmap, you attached, shows a way that should work, but uses 1000 steps to fill in the array.
Can you perhaps attach the VI, you mentioned? I seems to be missing...

I use command to create table :
create table elements of xmltype
xmlschema "http://192.168.1.1:8080/test.xsd"
element "publicKey"
. But why the result,table as object type. so i cant use command "desc <table_name>;"

cannot be the full story you tell. The exception is thrown in the context of a prepareForDML, which is called on entities for the Create / Update and Delete use case. I also see a failed rollback. So there must be something you do before this happens during a page refresh

Search in Nested Tables and Insert the result into new Nested Table!

How can I search in Nested Tables ex: (pr_travel_date_range,pr_bo_arr) using the SQL below and insert the result into a new Nested Table: ex:g_splited_range_arr.
Here are the DDL and DML SQLs;
Don't worry about the NUMBER( 8 )
CREATE OR REPLACE TYPE DATE_RANGE IS OBJECT ( start_date NUMBER( 8 ), end_date NUMBER( 8 ) );
CREATE OR REPLACE TYPE DATE_RANGE_ARR IS TABLE OF DATE_RANGE;
DECLARE

SELECT *
BULK COLLECT INTO g_splited_range_arr
FROM view_split_date(g_travel_range,g_bo_arr);

@riedelme
For your questions:
1) I don't want to store in the database as a nested table
2) I don't want to retrieve data from the database. Data will come from function split_date() parameter and data will be processed in the function and function will return it in nested table format. For more detail please look at the raw function SQL.
I have a SQL like:
WITH all_dates
        AS (SELECT tr_start_date AS a_date, 0 AS black_out_val FROM travel
            UNION ALL
            SELECT tr_end_date, 0 FROM travel
            UNION ALL
            SELECT bo_start_date - 1, 1 FROM black_out_dates
            UNION ALL
            SELECT bo_end_date + 1, -1 FROM black_out_dates),
     got_analytics
        AS (SELECT a_date AS start_date,
                   LEAD( a_date ) OVER (ORDER BY a_date, black_out_val)
                      AS end_date,
                   SUM( black_out_val ) OVER (ORDER BY a_date, black_out_val)
                      AS black_out_cnt
              FROM all_dates)
SELECT start_date, end_date
    FROM got_analytics
   WHERE black_out_cnt = 0 AND start_date < end_date
ORDER BY start_date;I want to change the tables black_out_dates and travel to Nested Array so I can use it in a function with Nested Array travel and Nested Array black_out_dates parameters and the function will return Nested Array of date ranges.
Here is what I want in raw SQL:
    DECLARE
       g_splited_range_arr   DATE_RANGE_ARR := DATE_RANGE_ARR( );
       g_travel_range        DATE_RANGE := DATE_RANGE( '20110101', '99991231' );
       g_bo_arr              DATE_RANGE_ARR := DATE_RANGE_ARR( DATE_RANGE( '20110312', '20110317' ), DATE_RANGE( '20110315', '20110329' ) );
       FUNCTION split_date_sql( pr_travel_date_range    DATE_RANGE,
                                pr_bo_arr               DATE_RANGE_ARR )

Urgent - pls help - Problem while inserting binary file into Oracle DB

Hi,
I am trying to insert binary files into a Blob column in a Oracle 10G table.
The binary files would be uploaded by the web users and hence come as multipart request. I use apache commons upload streaming API to handle it. Finally i am getting a input stream of the uploaded file.
The JDBC code is
PreparedStatement ps=conn.prepareStatement("insert into bincontent_table values(?)");
ps.setBinaryStream(1,inStream,length);
My problem starts when i try to find the length of the stream. available() method of inputstream does not return the full length of the stream. so i put a loop to read thru the stream and find the length as shown below
int length=0;
while((v=inStream.read())!=-1)
length++;
Now, though i got the length, my stream pointer has reached the end and i cant reset it(it throws an error if i try).
So i copied the stream content to a byte array and created an ByteArrayInputStream like this.
tempByteArray=new byte[length];
stream.read(tempByteArray,0,length);
ByteArrayInputStream bais=new ByteArrayInputStream(tempByteArray);
Now if i pass this bytearray input stream instead of the normal input stream to the prepared statement's setBinaryStream() method it throws an error as
"ORA-01460: unimplemented or unreasonable conversion requested".
Now how to solve this?
My doubts are ,
1) preparedStatement.setBinaryStream(int parameterIndex, InputStream x, int length) expects an inputstream and its length. if i have the stream how to find its length with out reading the stream?
2) Also as the length parameter is a integer, what if i have a large binary file whose length runs more than the capacity of integer
3) Alternatively there is a setBlob(int i, Blob x) in prepared statement. But how to instantiate a Blob object and set it here
4) Is there any better way to do this.
Thanks in advance

"ORA-01460: unimplemented or unreasonable conversion
requested".When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB (reference: javadoc)
1) preparedStatement.setBinaryStream(int parameterIndex,
InputStream x, int length) expects an inputstream and its length. if i
have the stream how to find its length with out reading the stream?no. stream may have no specified length. i think you have wrong understanding about stream.
2) Also as the length parameter is a integer, what if i have a large
binary file whose length runs more than the capacity of integer
3) Alternatively there is a setBlob(int i, Blob x) in prepared statement.
But how to instantiate a Blob object and set it here
4) Is there any better way to do this.use ps.setBlob(1, instream) instead
