How to extract a cluster controls array in 8.2 PDA Module

Hi Everyone,
I'm in the process of porting an application from LV 8.2 to LV 8.2 PDA. The application relies
heavily on using the controls[] property node which I just found out is not
supported in LV 8.2 PDA. Does anyone know of any alternative method of
extracting a cluster's controls array without using a property node?
I've attached an example of the application.
Thanks for your help,
John.

Hello Jon,
Currently, there is now way to obtain a reference to a control inside a cluster in LV PDA. I have experimented a great deal with alternatives, but to no avail. However, I think you you may be able to accomplish the same behavior using just an unbundle, or just using explicit controls outside of a cluster. Hopefully we will have that functionality in a future version of LabVIEW PDA.

How I pass a cluster with array of various data type (double, I32, string)

I have to pass from a VI to a Microsoft Visual C++ DLL, a cluster with some arrays of various data type. The problem is with Double array, that during Visual C debug is incorrect:the dimension is correct passed, but not array data. In the DLL I have inserted the C code genereted by LabVIEW. I tried to pass a cluster of only one array of double, and the results is the same. Then, I tried to pass a cluster with scalar number and the result is correct in only one case. If the double data is the first in the cluster, the result is correct; if the first is another data type, such as integer or boolean, the double data is incorrect during the debug of the DLL.
This is the code of my DLL:
// LabViewP
aram.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include "LabViewParam.h"
#include "extcode.h"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
switch (ul_reason_for_call)
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
return TRUE;
typedef struct {
long dimSize;
double elt[1];
} TD2;
typedef TD2 **TD2Hdl;
typedef struct {
TD2Hdl elt1;
} TD1;
// This is an example of an exported variable
LABVIEWPARAM_API int nLabViewParamPass=0;
// This is an example of an exported function.
LABVIEWPARAM_API int LabViewParamPass(TD1 *pparam)
double parametro;
int i;
for (i=0;i<(**(*pparam).elt1).dimSize;i++)
parametro=(**(*pparam).elt1).elt[i];
return 42;
// This is the constructor of a class that has been exp
orted.
// see LabViewParam.h for the class definition
CLabViewParam::CLabViewParam()
return;
I use LabVIEW 7.0 and Windows XP.
Sorry for my english.
Thanks to every one for your suggestions.

It is hard tell for sure, but you might have alignment problems. The
key symptom
is that you can pass a cluster of big and small fine, but
small big doesn't pass correctly. You might also test this by seeing
what the size of your struct is. For Boolean and Double, sizeof()
should return nine bytes no matter what order the array is in. If you
are getting different sizes, you have two options. You can either order
them such that the sizes work, or you can build the EXE or a wrapper DLL
so that the alignment matches LV's native alignment.

Printout a cluster control

Hello,
has anyone an idea how to printout a cluster control. When I print it with
"Append Control Image to Report" the I only have the empty frame printed
out.
regards
Marco

Are you using labVIEW 8.0??
There was a bug where in, the cluster was not properly saved while using append to control image.vi / get image method.
This was fixed in LabVIEW 8.2
Read this link for a suggested workaround in LabVIEW 8.0
Hope this helps,

Labview pda module: how can I resize image dynamically in an application?

Hello every one,
I am currently working on the development of an application on a PDA (brand Nomad) and whose OS is Windows Mobile. So I am using the PDA module of Labview 8.6.My problem is the following one: in my application I would like to be able to load images (thanks to their path) in pictures indicators. I load images with the labview “function PDA Image File Load.vi” and then my problem is that images don’t fit with the size of the indicator, and so I am only able to see the left top corner of the image…Of course, I would like to see the entire picture, but I don’t know how I can modify or resize a picture with the PDA Module, where most of the property nodes (zoom factor, scrollbars…for picures) are not available.Has someone ever faced and fixed that problem?? Any help would be really appreciated!! PS: Attached is one part of my application!

How to extract every component in an array?

Hello everyone!
Do you know how to extract every component from an array field?
For example:
The following is the defination of a table:
CREATE TABLE test (
id NUMBER PRIMARY KEY,
name VARCHAR2(32),
shape MDSYS.SDO_GEOMETRY
And then I insert a new record:
INSERT INTO test VALUES(
1,'first',
MDSYS.SDO_GEOMETRY(
2003,
NULL,
NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,3),
MDSYS.SDO_ORDINATE_ARRAY(1,1, 5,7)
The Question is I want to read the every component (for example 1,1,5,7) in the sdo_ordinate_array one by one. Who knows how to write the SQL?
I have tried "select a.shape.sdo_ordinates(1) from test a". But it can't work.
Thank you very much!

One solution is to read each ordinate from a cursor ina SQL block. Here is an example:
set serveroutput on
SET serveroutput on SIZE 1000000
set concat on
DEFINE layername = 'LAYER';
DEFINE geomcolname = 'GEOM';
DECLARE
id varchar2(10);
longitude number;
latitude number;
logmile number;
i number;
theLayer varchar2(32);
theGeomCol varchar2(32);
BEGIN
FOR rec IN (SELECT ROWID, id, &geomcolname FROM &layername ) LOOP
id := rec.id;
i := 1;
while i < rec.geom.sdo_ordinates.count loop
longitude:=rec.geom.sdo_ordinates(i);
latitude:=rec.geom.sdo_ordinates(i+1);
logmile:=rec.geom.sdo_ordinates(i+2);
dbms_output.put_line(id || ',' || longitude || ',' || latitude || ',' || logmile);
i := i + 3;
end loop;
END LOOP;
commit;
END;
Maybe that will help.

How to extract data from a file?

o to all labview users.
I am currently learning labview to control the network analyzer hp8720
as part of my project. Through my program, i am able to do a sweeping
function with my NA and the sweeping data are written to txt file. and
i want to extract the db value corresponding to a specific frequency.
my txt file is like the following:
MHz   dB
103     0.015
168     2.09
201     2.67e01
I know that we can extract certain selected data by using the some palettes like "read file" and "scan file"
I tried using "scan file" and i couldnt extract the data(ex: the dB
value corresponding to 168MHz) i want successfully....i checked the
help file and did put some syntax in the format string like (%[^2.09]),
but it seems the "scan file" palette was only able to scan the first
line, which gave me "Mhz db".....
is the format of my txt file not correct?
also, i tried using "read file" palettle..and i set the count to "-1"
to read the whole file. someone suggested on the forum that it is
easier to read the whole file and then use array to extract the
selected data.
How can i write to the array using "read file" while specifying the what range of data i want?
Instead of doing that, maybe i can just simply write the db value
related to the specific range of frequency while the program is in a
while loop doing sweeping?
It would be greatly appreciated if someone could me some guidance.
thank you very much

Hi, I have been reading this post It is very interesting and also I
need help. I am doing a project involving scattering matrix (S
parameter) using frequency and time domain analysis. In order to make
use of S parameter in frequency domain from Vector Network Analyzer, I
need to convert S parameters from frequency domain (sweep from 8.2 GHz
to 12.4 GHz) to time domain using inverse chirp z transform or any. I
have no idea how to implement it. Could you please help or guide me how
to implement them. I am using Labview 8.0 and matlab. Please see the attached file for the data in frequency domain both linear , dB magnitude and phase.
Thank you so much for any help.

Look inside the palette called Signal Processing - Waveform measurements. There are a lot of functions here that you can use to get the information you desire. For instance, the Extract Tones function will output an array of clusters, with each cluster element giving the frequency, amplitude, and phase of the signal component. Go through the entire arry to see each frequency component of the complex waveform.
Also, in the Waveforms palette there is the Get Waveform Components function that will give you t0, dt, and Y components of the waveform. 1/dt should give you the sample rate. See attached VI.

How to disable individual elements in array

How do I disable individual elements in an array at runtime.

I assume you are referring to the control property "disabled".
If so there is no way to disable a single element of an array. By definition an array is a collection of data, it is not a collection of controls. A fine line but an important one. So you can configure the single control that makes up the array and defines its type. For example, if you have an array of Booleans, you can change the color of the Boolean. However this will change the color of all the Booleans in the array. It is 1 control, with a lot of values.
Part of the reason for this is memory. Imagine an array of 1 million elements. If you could set the properties of each element, then to store that array would be incredibly large. It would be 1 million U8s for example, but then all the properties for each 1 million elements would also need to be saved. Therefore your 1 million element array of bytes could easily represent 100 million bytes in memory.
Let me know if this explanation makes no sense, I usually explain it better, but I think I need more coffee.
The way around this is clusters. You can change each element in a cluster, so if your array is of a manageable size, change your array control into a cluster of n elements. You can then use the cluster to array function to convert the data to the array of data you need. Unfortunately this method means that before runtime you must know the maximum number of elements you will need. You can always hide the extras, but you can not create more during execution.

NetBeans MobilityPack 5 BUG?? how can I send a byte array?

I�ve created a WebApp and a Simple servlet with one public method.
public byte[] getStr(byte[] b) {
String s = "A string";
return s.getBytes();
Then I've used "Mobile To Web App" wizard to generate stubs to that getStr method. And when I�ve tried to call that getStr method:
byte[] aByte = "st".getBytes();
byte[] b = client.getStr(aByte);
I've got an error at Server in Utility.java in generated ReadArray method.
* Reads an array from the given data source and returns it.
*@param source The source from which the data is extracted.
*@return The array from the data source
*@exception IOException If an error occured while reading the data.
public static Object readArray(DataInput in) throws IOException {
short type = in.readShort();
int length = in.readInt();
if (length == -1) {

} else {
switch (type) {

in.readFully(data);
return data;
default: {
throw new IllegalArgumentException("Unsupported return type (" + type + ")");
At this line "in.readFully(data);" I�ve got an EOFException.
The the aByte = "st".getBytes(); was 2bytes long and at the server "int length = in.readInt();" it was 363273. Why?
All code was generated by NetBeans Mobility pack 5 it's not mine so its a bug?
How can I fix this?

I found that bug. I've described it here

How to extract text from a PDF file?

Hello Suners,
i need to know how to extract text from a pdf file?
does anyone know what is the character encoding in pdf file, when i use an input stream to read the file it gives encrypted characters not the original text in the file.
is there any procedures i should do while reading a pdf file,
File f=new File("D:/File.pdf");
               FileReader fr=new FileReader(f);
               BufferedReader br=new BufferedReader(fr);
               String s=br.readLine();any help will be deeply appreciated.

First, you set i once, and then loop without ever changing it. So your loop body will execute either 0 times or infinitely many times, writing the same byte every time. Actually, maybe it'll execute once and then throw an ArrayIndexOutOfBoundsException. That's basic java looping, and you're going to need a firm grip on that before you try to do anything as advanced as PDF reading. the case.oops you are absolutely right that was a silly mistake to forget that,
Second, what do the docs for getPageContent say? Do they say that it simply gives you the text on the page as if the thing were a simple text doc? I'd be surprised if that's the case.getPageContent return array of bytes so the question will be:

How to extract data from Chart History?

Dear all, I have read a lot of posts, but still don't understand how to extract data from Chart history.
Suppose you acquired 1024 points of data every time, then use "build array" to build an array, then send to intensity chart to show, then save the history into a .txt file, but how to extact data from the file?
How Labview store the data in the 2D history buffer?
Anybody has any examples?

The simplest would be to save the 2D array as a spreadsheet file, the read it back the same way.
Maybe the attached simple example can give you some ideas (LabVIEW 7.1). Just run it. At any time, press "write to file". At any later time, you can read the save data into the second history chart.
If you are worried about performance, it might be better to use binary files, but it will be a little more complicated. See how far you get.

How to extract information in cells of a mult-column list box?

I have multi column list box. At run time this listbox allow me to select entire row (this is fine), how to extract the data from each cell along the selected row? It seems to me that the Multi column Listbox (MCL) is merely a 1D array (I guess index of this 1D array corresponds to row index of the MCL and value of the element corresponds to column index of MCL.)

To extract cell values of the selected row, you can create a property node for the MCL. From this property node, choose "Item Names". This is a 2D array containing all cell values. Index this array with the MCL terminal. Note that you must choose the scalar data type for the MCL. To choose the scalar data type, right click on the MCL and go to "Selection Mode"->"Data Type"->"Scalar".
See attachment written with LabVIEW 6.
I hope it will help you.
