Passing array to DLL

Hi -
I need to interface with a DLL. I can communicate fine with most of the functions, but I can't figure out how to configure Call Library Function for "GPIO_Init". Can anyone with more experience help me out? I've attached the header, and also the manual - it's section 3.8.1 (page 37)
Many thanks,
Jon.

See this recent thread with approximately the same question: http://forums.ni.com/t5/LabVIEW/FTDI-FT4222-DLL-calling/m-p/3146709
In this case, you pass a LabVIEW array and configure the array parameter as an array, passed by array data pointer.

Pass array to "Labview 7" DLL in Visual Basic

Hi!
I would like to pass arrays in Visual Basic to a LV DLL made in Labview 7.
I've seen the examples of NI to create a dll in Labview for Visual Basic and for passing arrays, but all the examples were made with Labview 6.
The problem is that in the tutorial they say to define the Pass By of the argument as Array Data Pointer, but in Labview 7 when I add an array as an argument I don't have that option.. It's always defined as TD1Hdl* inArray, and in Labview 6 it was defined as float64 inArray[].
Can I use the TD1Hdl structure in Visual Basic? How do I use it?
Thanks!

Unfortunately, i'm not expert in Visual Basic, i need to investigate in your problem.
See link below, that explain how you can use LabVIEW DLL in Visual Basic.

Passing Array of Srings between Visual Basic and Labview dll

I have searched and searched for the correct way to pass an array of
strings between Visual Basic 6.0 and a Labview 7 dll. So far, I still
do not know how to pass the array. When I create the dll in LV, the
array of strings is presented as a string, not an array. I am familiar
with passing arrays of type double, but I really need to know how to
pass an array of strings. Any and all help is appreciated.
Bob

Hey Bob,
From what I understand, that can get kind of messy. You have to allocate the memory in VB in the format that LabVIEW expects (see the externalcode.h file in National Instruments\LabVIEW 7.0\cintools for details). Then pass a pointer to that location to LabVIEW. There are a couple of related examples online. They don't necessarily show how to pass an array of strings to VB, but they should show how to pass a string and an array. I hope this helps.

Array into dll

I built a dll in LV 7. One of the inputs was an array of strings. LV created the following typedef for this input:
typedef struct {
long dimSize;
LStrHandle elt[1];
} TD2;
typedef TD2 **TD2Hdl;
The function prototype generated by LV is:
void __stdcall AddRow(TD1 *errorInNoError, TD2Hdl *TestResult,
LVRefNum *WordTableIn, LVRefNum *WordSelectionIn, TD1 *errorOut);
The question is to call this function, what do I have to pass into the dll from LV? I've tried several ways and it keeps crashing. When I create the dll, it doesn't give me the option to define the input as an array, it just creates the typedef. So when I configured the dll, I chose "Adapt to Type". This didn't work with either "Handle by Value" or "Pointer to Handle". If
I configure the input as an Array, there is no string type listed (uint32 maybe?)
TIA

Complex arrays for DLLs

I have spent a lot of time trying to pass arrays of complex numbers between LabVIEW and a DLL I have written in C++, but with no success. The data types I wish to interface with in the C++ are things like std::vector<std::complex<float> > and std::vector<std::complex<int16_t> > (or just the basic arrays they contain). However, I would be willing to use any sensible data representation (i.e. such that I don't need to shift it around in memory unnecessarily).
I have gone through all the DLL examples in LabVIEW 2013, which include complex numbers and arrays, but not arrays of complex numbers. I tried using the typedef struct approach for handling complex numbers (suggested in one example). This works fine within my C++ code: I can reinterpret_cast<...>(...) to get back to arrays of std::complex. However, every attempt at interfacing this with LabVIEW has failed in a variety of ways. At best, I managed to get some garbled numbers passing back and forth.
So, does anyone know where I can find a (very) basic example/step-by-step guide to passing complex arrays between LabVIEW and DLLs? Given that this is trivial in C++, I imagine there must be a straightforward solution out there somewhere.
Many thanks!

A LabVIEW complex number is simply a structure with the imaginary and real value both represented as a floating point number. As such there is very little you can do on the LabVIEW side to change that. C++ object pointers are compiler specific and often even dependent on the version of the template library that was used to compile them. As such there is absolutely NO way to use them in any code that needs to be called from code that was not compiled with the same C++ compiler and the same compile settings. You can bend in circles and jump through hoops but there is simply no way to get around that.
The only C++ object oriented framework that I know and avoids this limitation for the most part is the COM/DCOM standard which imposes certain limits on object interfaces so that you can get around the compiler specific ABI conventions, but only if you are very careful about how you invoke the compiler. With a bit of macro magic that can be enabled in the IDL precompiler you can even call COM/DCOM objects from standard C. Also COM/DCOM definitely will not work wth C++ template libraries and the like.

How can i pass array as argument in magento api method calling using sudzc API in iphone Native APP

0down votefavorite
I am implementing magento standard api method in native iphone app. I use webservice generated by sudzc. To call method I use:
[service call:self action:@selector(callHandler:) sessionId:@" " resourcePath:@" " args:@""];
When I used methods e.g. cart.info or product.info in which I have to pass one parameter; it gives valid response. But when I used method e.g. cart_product.add in which I have to pass an argument as value of array it gives error
SQLSTATE[42000]: Syntax error or access violation:
1064 You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1
I have tested in SOAP UI also. There also it gives me same error. But same method works in PHP file. Even I tried by creating same soap request which I created using JavaScript but still it doesn't work.
Can anyone help me to pass array as a parameter using sudzc api to call magento web services?

There is an error in your SQL.

How to pass array into xslt from java

i have a xslt in which i am passing some parameter from java there is one parameter which is a array in java which i need to pass becouse array length is not defined so that xslt will work dynakically according to the parameter.
right now i am passing parameter but not able to send the array parameter that's why my code is not fully dynamic
please give suggestion.
anagh

it is not possible to pass array by using XSLT, you can wirite all values into a String with certain delim symbol, pass this string, then use xsl.substring() to get different values.

Passing array into resultset

hi,
is it possible to pass an array into a resultset? if yes please indicate how.
thank you all in advance

Hi,
Sorry for the confusion, here's what I'm trying to accomplish.
I'm trying to create a report in Crystal Report and use Java as data source. My Java application needs to generate some value and pass them to the report as parameters. After some research I've found that I can use a Java Bean class as data source for Crystal Report that returns a ResultSet. Therefore I'm trying to pass some values in my Java app into the Bean class as array and convert them to a ResultSet for Crystal Report.
If you know of a different way please let me know, otherwise, this is what I meant by passing array into resultset.
thanks for your reply,

Can some one please help me understanding how can I pass array from JSP page to a stored procedure in database.
Thanks in advance.
Jatinder

Thanks.
I tried ArrayExampla.java and was successful in passing array values to the stored database procedure.
How can I use this class in JSP? Like I have first JSP where in I will collect input from the user and then submit it to the second JSP - that needs to call the ArrayExample.java to pass the values as array to the database.
How should I call this java code in my second JSP?

Pass array to oracle stored procedure

I have such a problem: I have to pass array to stored procedure, so I declare type:
create type tNumberArray as table of number
and create procedure:
create or replace procedure proc_1 (in_param in tNumberArray) as
.... BODY OF PROCEDURE ...
when I call this procedure from C# like this:
int []pParam = new int[3] {1,2,3};
OracleCommand cmd = new OracleCommand("proc_1", dbConn);
cmd.CommandType = CommandType.StoredProcedure;
OracleParameter param14 = new OracleParameter("param", OracleDbType.Decimal);
param14.Value = pParam;
param14.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
param14.Size = 3;
param14.Direction = ParameterDirection.Input;
cmd.Parameters.Add(param14);
cmd.ExecuteNonQuery();
an error occures. It say that there invalid number or type of parameters.
But when I declare both type and procedure in a package everything goes fine.
What is the matter? Did anybody have the same problem?

Not I got next problem:
when I cannot pass parameter to stored procedure and get array fro it. In other words returning array from procedure and passing some input parameters to it does not word!
Does anybody know why it happens?

Passing arrays to methods?

Hi all,
Thanks to most of the main contributors in this forum nearly all of my major hurdles in transitioning from proc-C to Cocoa have been overcome. However, while I was shown how to use NSMutableArray in conjunction with NSDictionary to do pretty much the same job as a C-style multi-dimensional array, dictionaries aren't always the perfect solution in every situation. So, let's suppose I wanted to construct a pure Cocoa facsimile of a C-style [4][x] array like this...
NSArray *replicaArray = [NSArray arrayWithObjects:
[NSNull null], // index 0 (unused)
[NSMutableArray array], // index 1
[NSMutableArray array], // index 2
[NSMutableArray array],nil]; // index 3
I threw in an NSNull as the first array object because (whenever possible) I adopted the habit of leaving row0 and column0 of multidimensional arrays unused to make for more natural, readable iteration ops and stuff. The above code works perfectly well, but with 4-5 different arrays in the same proc-C apps I often had to pass them to common functions (to handle things like bubble-sorting etc.) like the one below:
void bubbleSortSimpleArray (short arry[ ], short numsToSort)
short ctr,loopCtr,storeValue;
for (loopCtr = 1; loopCtr <= numsToSort; loopCtr++)
ctr = 1;
while (ctr < numsToSort)
if (arry[ctr] > arry[ctr+1])
storeValue = arry[ctr+1];
arry[ctr+1] = arry[ctr];
arry[ctr] = storeValue;
++ctr;
Of course, thanks to the advantages of Cocoa this entire code block can be replaced in just a couple lines with 'sortUsingSelector'. Sorry for the lengthy outline in attempting to describe my problem as clearly as possible , but (finally) _is it possible to pass arrays to methods_ in our Cocoa code in a similar way? I was thinking something along the lines of:
- (void)doMoreProcessing:(id)array
//do some other common stuff on my array(s) here...
That'd simplify converting some of my old code and be a real bonus for me, but I haven't been able to find any reference about this on the net so far, and experimenting with my code hasn't provided me with any answers yet, either... Any guidance on this would be very much appreciated!
Thanks in advance.
Ernie

Hi Bang A. Lore,
Thanks for your input but I've got it figured out now However, while you quite correctly say:
Pointers work the same way as they do in C.
the cause of my problems wasn't a lack of understanding of pointers, but by the syntax differences between proc-C and obj-C. I'm well aware of the fact that the name of a passed array is just a pointer to its address in memory of course, but attempting to use a mandatory 'C' style header declaration along the lines of:
- (void)test2DArray:(NSMutableArray*)array[][];
just kept giving me parse errors, as did any attempt to use square brackets in the implementation file. While 'C' insists on using them, I found (after some more experimentation) that obj-C will quite happily accept:
- (void)test2DArray:(NSMutableArray*)array;
...or the even simpler...
- (void)test2DArray:(id)array;
Also pleasantly surprised to find that Cocoa doesn't seem to give a hoot whether the (array) object you pass it is flat OR multidimensional -- whereas 'C' insists you even provide the called function with the number of rows contained in a multi-subscripted array -- which often meant I had to include two versions of many functions containing identical code, depending on whether they were called by 1D or 2D arrays.
Once I hit on the idea of omitting the square brackets entirely (just to stop the darned parse errors and see what would happen out of curiosity), the problem just went away.
Thanks once again. Appreciate it!

Passing Array of java objects to and from oracle database-Complete Example

Hi all ,
I am posting a working example of Passing Array of java objects to and from oracle database . I have struggled a lot to get it working and since finally its working , postinmg it here so that it coudl be helpful to the rest of the folks.
First thinsg first
i) Create a Java Value Object which you want to pass .
create or replace and compile java source named Person as
import java.sql.*;
import java.io.*;
public class Person implements SQLData
private String sql_type = "PERSON_T";
public int person_id;
public String person_name;
public Person () {}
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
person_id = stream.readInt();
person_name = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeInt (person_id);
stream.writeString (person_name);
ii) Once you created a Java class compile this class in sql plus. Just Copy paste and run it in SQL .
you should see a message called "Java created."
iii) Now create your object Types
CREATE TYPE person_t AS OBJECT
EXTERNAL NAME 'Person' LANGUAGE JAVA
USING SQLData (
person_id NUMBER(9) EXTERNAL NAME 'person_id',
person_name VARCHAR2(30) EXTERNAL NAME 'person_name'
iv) Now create a table of Objects
CREATE TYPE person_tab IS TABLE OF person_t;
v) Now create your procedure . Ensure that you create dummy table called "person_test" for loggiing values.
create or replace
procedure give_me_an_array( p_array in person_tab,p_arrayout out person_tab)
as
l_person_id Number;
l_person_name Varchar2(200);
l_person person_t;
l_p_arrayout person_tab;
errm Varchar2(2000);
begin
     l_p_arrayout := person_tab();
for i in 1 .. p_array.count
loop
     l_p_arrayout.extend;
     insert into person_test values(p_array(i).person_id, 'in Record '||p_array(i).person_name);
     l_person_id := p_array(i).person_id;
     l_person_name := p_array(i).person_name;
     l_person := person_t(null,null);
     l_person.person_id := l_person_id + 5;
     l_person.person_name := 'Out Record ' ||l_person_name ;
     l_p_arrayout(i) := l_person;
end loop;
p_arrayout := l_p_arrayout;
     l_person_id := p_arrayout.count;
for i in 1 .. p_arrayout.count
loop
insert into person_test values(l_person_id, p_arrayout(i).person_name);
end loop;
commit;
EXCEPTION WHEN OTHERS THEN
     errm := SQLERRM;
     insert into person_test values(-1, errm);
     commit;
end;
vi) Now finally create your java class which will invoke the pl/sql procedure and get the updated value array and then display it on your screen>Alternatively you can also check the "person_test" tbale
import java.util.Date;
import java.io.*;

( "begin give_me_an_array(?,?); end;" );
ps.setARRAY( 1, array_to_pass );
     ps.registerOutParameter( 2, OracleTypes.ARRAY,"PERSON_TAB" );
     ps.execute();
     oracle.sql.ARRAY returnArray = (oracle.sql.ARRAY)ps.getArray(2);
Object[] personDetails = (Object[]) returnArray.getArray();
Person person_record = new Person();
for (int i = 0; i < personDetails.length; i++) {
          person_record = (Person)personDetails;
          System.out.println( "row " + i + " = '" + person_record.person_name +"'" );
                    public static void main (String args[]){
     try
                         ArrayDemo tfc = new ArrayDemo();
                         tfc.passArray();
     catch(Exception e) {
                    e.printStackTrace();
          public static Connection getConnection() {
     try
                         Class.forName ("oracle.jdbc.OracleDriver");
                         return DriverManager.getConnection("jdbc:oracle:thin:@<<HostNanem>>:1523:VIS",
                         "username", "password");
     catch(Exception SQLe) {
                    System.out.println("IN EXCEPTION BLOCK ");
                    return null;
and thats it. you are done.
Hope it atleast helps people to get started. Comments are appreciated. I can be reached at ([email protected]) or [email protected]

Hi Sunil,
I've a similar situation where I'm trying to insert Java objects in db using bulk insert. My issue is with performance for which I've created a new thread.
http://forum.java.sun.com/thread.jspa?threadID=5270260&tstart=30
I ran into your code and looked into it. You've used the Person object array and directly passing it to the oracle.sql.ARRAY constructor. Just curios if this works, cos my understanding is that you need to create a oracle.sql.STRUCT out of ur java object collection and pass it to the ARRAY constructor. I tried ur way but got this runtime exception.
java.sql.SQLException: Fail to convert to internal representation: JavaBulkInsertNew$Option@10bbf9e

                    at JavaBulkInsertNew.main(JavaBulkInsertNew.java:76)
Here's a code snippet I used :
Object optionVal[] =   {optionArr[0]};   // optionArr[0] is an Option object which has three properties
oracle.sql.ArrayDescriptor empArrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("TT_EMP_TEST",conn);
ARRAY empArray = new ARRAY(empArrayDescriptor,conn,optionVal);If you visit my thread, u'll see that I'm using STRUCT and then pass it to the ARRAY constructor, which works well, except for the performance issue.
I'll appreciate if you can provide some information.

Passing array of Types to java class

I am trying to pass a user defined type (that is an array) from PL/Sql to a javaclass. Here are the definitions that make-up the parameter to pass from PL/Sql to Java (uri_digest_array):
CREATE OR REPLACE TYPE uri_digest as object (uri VARCHAR2(256),
digest_value CLOB);
CREATE OR REPLACE TYPE uri_digest_array AS VARRAY(10) OF uri_digest;
In Oracle-land, java classes are published to PL/Sql by way of the following definition. Note that the intent here is to have compatible data-types.
CREATE OR REPLACE FUNCTION SIGNRETURNINGXML (p_array IN uri_digest_array)
RETURN LONG
AS LANGUAGE JAVA
NAME 'SignReturningXml.main(oracle.sql.Array) return java.lang.String';
Here is a fragment of the java class code:
class SignReturningXml {
public static String main(String [] [] signItems ) // I have no idea what datatype to use here!
{ . . . . The code in here would process the passed array normally from first entry to last.
Currently I get the following error:
PLS-00311: the declaration of
"SignReturningXml.main(oracle.sql.Array) return
java.lang.String" is incomplete or malformed
I could use some suggestions on resolving the datatype conflicts. Any ideas? Has anyone tried this kind of thing?
Thanks,
Michael

Michael,
At the risk of another [non] useful response, I meant that you should try searching the "Ask Tom" Web site, because usually you will find an answer to your question that has already been asked by someone else. Perhaps these will be helpful:
