Custom Data Types

Hi! I am just starting to build Java and I am having this problem.It's so much .doc about Java but I still can't find what I need. My problem:
I should define(in a class or interface or something else) a custom data type like : uint16, or uint32, which means that instead of writing : int j; , I should be able to write : uint16 j; which means an unsigned integer(positive) on 16 bits(eg. short). And this not only in one file, but in any file I want to, and to be able to transport this through TCP. Thank you a lot if you can help me.

Ok, you could use some API that provides uint16, uint32,... classes or you could write your own. But this is really not something you would ever do in practical use except perhaps for interoperability with other languages. In that case you will not be able to use +,-,*,/,==,!=,>,<, and so forth, due to the lack of operator overloading in Java. It is not supported in Java by good reasons.
In my opinion here somebody did bad work in constructing an exercise for your training. :-)

Sven

I am new to Teststand software interface. While doing my first software release under the guidance of a more experienced colleague, we discovered that Teststand will not run if it detects version number conflicts between custom data types on my machine vs. the production test machine. I verified differences between all .seq files in my test program directory, but I did not realize that the version number difference exists in the StationGlobals.ini file, which is stored in a different location. After discovering this, I modified the version number in one of the files. However, two releases later, I discovered that the version number mismatches in another two files. This raises several questions for me :
1. Is there a way in Teststand to view all the .seq files where a custom data type is used and then change its version number in one attempt?
2. Under what instances does Teststand upgrade the version number of a custom data type?
3. Are there any tools or scripts within Teststand that can allow the version number of custom data types to be changed in all .ini files when a difference is discovered between the current production test station settings and a new release?
Please help.

Have you read this? http://zone.ni.com/devzone/cda/tut/p/id/7060
I can tell you that your situation is not uncommon with TestStand. The key is just doing it right the first time. haha
#1- I doubt that this is possible because then TestStand would have to know every location of every .seq on the machine. You will only see it when you open the sequence file.
#2- TestStand updates the version every time you change it. You should get a message popup when you try to save that asks if you want to increment the version or not. There's also a check box that says Remove Modified Mark From Types. Look under Station Options in the File tab. There are some settings there about Type conflicts.

Issue with creating array of custom data type - WebLogic Integration

Hi,
We are doing WebLogic integration with Siebel for which from Siebel side we have generated java wrapper class which has all the methods, input\outputs defined and in\out params are serialized along with get\set methods. Following are the details of the input\output args.
Account_EMRIO.java
public class Account_EMRIO implements Serializable, Cloneable, SiebelHierarchy {
protected String fIntObjectFormat = null;
protected String fMessageType = "Integration Object";
protected String fMessageId = null;
protected String fIntObjectName = "Account_EMR";
protected String fOutputIntObjectName = "Account_EMR";
protected ArrayList <AccountIC> fintObjInst = null;
Above class also includes constructors\overloaded constructor\getters\setters
public AccountIC getfintObjInst() {
if(fintObjInst != null) {
return (AccountIC)fintObjInst.clone();
}else{
return null;
public void setfintObjInst(AccountIC val) {
if(val != null) {
if(fintObjInst == null) {
fintObjInst = new ArrayList<AccountIC>();
fintObjInst.add(val);
For the nested user defined data type AccountIC, it is defined in another java class as below
AccountIC.java
public class AccountIC implements Serializable, Cloneable, SiebelHierarchy {
protected String fname = null;
protected String fParent_Account_Id= null;
protected String fPrimary_Organization = null;
With the above, I was able to get all the AccountIC in the wsdl correctly and using this I was able to set the input param in the client
WSDL:
<xs:complexType name="accountEMRIO">
<xs:sequence>
<xs:element name="fIntObjectFormat" type="xs:string" minOccurs="0"/>
<xs:element name="fIntObjectName" type="xs:string" minOccurs="0"/>
<xs:element name="fMessageId" type="xs:string" minOccurs="0"/>
<xs:element name="fMessageType" type="xs:string" minOccurs="0"/>
<xs:element name="fOutputIntObjectName" type="xs:string" minOccurs="0"/>
<xs:element name="fintObjInst" type="tns:accountIC" minOccurs="0"/>
</xs:sequence>
<xs:complexType name="accountIC">
<xs:sequence>
<xs:element name="fName" type="xs:string" minOccurs="0"/>
<xs:element name="fParent_Account_Id" type="xs:string" minOccurs="0"/>
<xs:element name="fPrimary_Organization" type="xs:string" minOccurs="0"/>
minOccurs="0"/>
</xs:sequence>
</xs:complexType>
Now, I wanted to make slight difference in getter method of class Account_EMRIO method getfintObjInst so that an array of AccountIC is retured as output.
public ArrayList<AccountIC> getfintObjInst() {
if(fintObjInst != null) {
return (ArrayList<AccountIC>)fintObjInst.clone();
}else{
return null;
With the above change, once the wsdl is generated, I am no longer getting fintObjInst field for AccountIC due to which I am unable to get the array list of accountIC
WSDL:
<xs:complexType name="accountEMRIO">
<xs:sequence>
<xs:element name="fIntObjectFormat" type="xs:string" minOccurs="0"/>
<xs:element name="fIntObjectName" type="xs:string" minOccurs="0"/>
<xs:element name="fMessageId" type="xs:string" minOccurs="0"/>
<xs:element name="fMessageType" type="xs:string" minOccurs="0"/>
<xs:element name="fOutputIntObjectName" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
The issue that I am facing here is, we have a custom data type(AccountIC) which has several fields in it. In the output I need a array of AccountIC. In the java bean, when this type was defined as
protected ArrayList <AccountIC> fintObjInst = null; I was unable to get a array of AccountIC. this gets complicated as inside a AccountIC there is array of contacts as well and all the time I am getting just the first records and not a array.
To summarize: How to get xsd:list or maxoccurs property for a field in WSDL for the user defined\custom datatype?
Can someone help me with this.
Thanks,
Sudha.

can someone help with this??

Custom data type causing trouble in deploying shared variable to RT target

I seem to be having some difficulty in using a network published shared variable created from a custom data type when deployed as an executable on an RT cRIO target. I'll start by describing why I believe this is where the problem lies. I created my RT VI in the LabVIEW development environment (LV 2012) and everything works fine. This VI is pretty simple because it rapidly devolved in to a debug exercise. The RT VI starts by simply blinking the User LED a couple of times and then starts a simple acquisition loop to read a few values off the hardware using the scan engine (while still blinking the User LED). After reading the hardware, the values are bundled in to a cluster and written to a network-published shared variable defined by a type def custom control. The custom control contains five dbl precision floats. If it matters, the cRIO RT system hosts the shared variable in this case.
So, I deploy this under the development environment and everything works fine. The LED blinks merrily along, telling me that the program is running properly. Running a host VI that reads the network-published shared variable yields the desired result. All is good.
Now I want the cRIO system to run this simple program autonomously at startup. I build it, set it as the startup VI, deploy it and then restart the cRIO target. The LED never starts blinking... the VI does not seem to run. I will spare you most of the debugging work and jump to the end. I basically "Diagram Disabled" various sections of code until the VI started running correctly as an executable. I kept reducing the size of the disabled code until only one thing was disabled: the write to the custom data type shared variable.
So, I guess my question is this: Are custom data types defined by type def'd custom controls allowed in executable RT programs? I've read through the cRIO Developers Guide, my NI Real Time Development course book and the Using Shared Variables white paper and I didn't see anything that forbade it. I know that there are some things not allowed in executables that are allowed in the development environment (front panel property nodes, dialog VIs, OS-specific calls, etc), but no mention of custom data type shared variables. Any ideas as to why my VI runs in the development environment but fails when compiled unless I remove the write to the network published shared variable?
Thanks in advance for your help!!
Solved!
Go to Solution.

Paolo,
So I thought that you meant to disconnect them in the build specification. Under the Additional Exclusions in the build specification, there is a check box for Disconnect Type Defs. I checked that box, recompiled, redeployed and it did not work. At this point I had to give and move forward, so I was going to convert the data typed from a cluster to an array. When I went in to change the data type in the shared variable pop-up from the project explorer, there was a big button under the variable definition that "Disconnect from Type Def". Clicked that button, recompiled, redeployed, restarted and everything worked great. Thank You!!
I suspect that I'll have to be careful if I change the definition of that data type (add an element, etc) since it is no longer connected to the data type. We'll cross that bridge when we need to.
Thanks again

Designer Custom Data Type

Hello,
I've posted a project at some commercial sites to find someone to help me doing it, but couldn't find any. I thought that it might be impossible doing this type of projects. The following is what was posted expecting someone could help/lead me doing it myself or at least providing any valuable hints, Thank you in advance.
Looking for an Oracle expert to do the software part of a project.
A data to be populated in Oracle database, but unfortunately Oracle doesn't support the required data type to hold it.
An expert has to create custom data type with all required procedures/functions to manipulate the data(Read/Update/Insert/Delete), and provide a method to incorporate the solution in Oracle developer suite to model it.(To use it inside designer tools)
The solution should allow someone to Create a column in a table to hold (for example) three bits in every row(record), mostly used in the project is three bits, but need the solution to be open and customizable to any number from one up to 21. Viewing/entering the data in a record could be as binary string. Saving in a table physically should be in sampling way to save space.
The functions/procedures for manipulating the data should be based on record level and block level(several records of one column with start/end points). For record manipulations a binary string should be used, and for block manipulations a sampled structure should be used.
Thank you for your time.

not sure what exactly do you mean by custom data type in SQL? if you mean if there is a user defined data type in oracle thru PL/SQL yes there is. by using the %Type you need not to declare the variable data type explicitly. all you need to do is associate the variable to the column name of the table and use the %Type. see this example below.
SQL> declare
2    vEmpno   emp.empno%Type;
3 begin
4    select empno
5      into vEmpno
6      from emp
7     where ename = 'FORD';
8    dbms_output.put_line('employee no: '||vEmpno);
9 end;

How to access the Custom Data type variable given in Expression edit control To and From LabVIEW

Hello, I would like to know how to access the custom data type variable given in the Espression Edit Control from LabVIEW and vice-versa
Say, the FileGlobals.Reference_Handle (Custom Data Type Variable) contains the
VISA I/O session (Which in turn contains VISA_DeviceName: String, Session: Number),
Channel1: Number and
Channel2: Number
I am expecting the user to give FileGlobals.Reference_Handle as the input at the ExpressionEdit Control in the edit screen of the VI Call.
I would like to know how to get the values of this custom data type to LabVIEW?
Say, if I have the Cluster in LabVIEW like VISA I/O session (Deive Name and Session Number), Channel1 and Channel2
how do i need to set this cluster to the Custom Data type variable in TestStand?
Thanks and Regards
Prakash

Hi,
TestStand to LabVIEW: i didnt understand what you r trying to achieve. But if you are using references, Use Property nodes and Invoke nodes to achieve what you want in LabVIEW.
LabVIEW to TestStand: check the image below: You need to click the button next to 'container'. I have used a cluster output in the VI.
Hope this helps

Call Oracle procedure with custom data type within Java and Hibernate

I have a custom date TYPE in Oracle
like
CREATE TYPE DATEARRAY AS TABLE OF DATE;
and I have a Oracle function also
like
CREATE OR REPLACE FUNCTION doesContain (list DATEARRAY, val VARCHAR2) RETURN NUMBER
IS
END doesContain;
In my Java class,
I have a collection which contain a list of java.util.Date objects
When I call Oracle function "doesContain", how to pass my java collection to this Oracle function ...
anyone can provide solutions?
Please !!!
Thanks,
Pulikkottil

Vu,
First of all you need to define your types as database types, for example:
create or replace type T_ID as table of number(5)Then you need to use the "oracle.sql.ARRAY" class. You can search this forum's archives for the term "ARRAY" in order to find more details and you can also find some samples via the JDBC Web page at the OTN Web site.
Good Luck,
Avi.

Problems with Custom Data Types when converting from TS 1.0 to 3.0.

I am currently involved in the process of converting a test environment from TestStand 1.0, LabVIEW 5.1, and Windows NT to TestStand 3.0, LabVIEW 7.0, and Windows XP. We use a custom Operator Interface developed in LV. Based on the entered Model and Serial number, the appropriate Test Sequence is called. We also use a custom Process Model. The steps in the Test Sequence are either LV code modules or DLLs created in C++. We have LV SubVIs and C++ API functions that allow the developers of the test steps to add data to various Custom Data Types. For example, a developer may set up a test to add a note (Step.Result.Notes[x].String) when the test fails. Step.Result.Notes is a container for an array of strings. The attempt to set a note first attempts to use SetDimensions to redimension the array, then SetValString to set the value. These notes are added to the report. On the old system, everything worked fine. A note could be added to any result. On the new system, if a note is added to say the 5th result, but results 1-4 do not have a note, the test sequence ends and the Operator Interface returns to waiting for data entry (as if no test ever happened). No report is generated. The LabVIEW libraries have been modified to solve this problem by calling SetDimensions to incrementally increase the array size by one, and populating the unused TestStand array elements with an empty array of LabVIEW strings using the SetValString call . In other words, based on the previous example, if the user wants to set a note for the 5th result, the notes for results 1-4 must first be sent an empty array of strings. The report will only display the note for Result 5 (as desired). In addition to this being cumbersome, attempting to implement the same workaround in the C++ API has been unsuccessful because even though the note arrays for unwanted notes (1-4) is initialized with nothing, it is still displayed as a note (empty) on the report. If anybody knows what is wrong and what the solution is, it will be appreciated.

Aaron,
Thanks for your reply. I will attempt to clarify. I am working with a single step. The step calls a DLL. The DLL performs many 'checks' on the UUT (e.g. Model Number Check, Serial Number Check, Calibration Constants Check, etc.). Under the Type Palette - MyTypes.ini, we have a Step Type called TEST_DLL with a container in it called Results. In the Results container are a number of things, but I will only list the important ones:
Notes (Array of Type 'Notes'; Type 'Notes' is a Custom Data Type (container, Type Definition)containing an array of strings called 'String')
-Notes are generally set when on of the checks fails, otherwise no Note is set for the check.
Val (Array of Type 'Val'; Type 'Val' is Custom Data Type (container, Type Definition) containing a Boolean called 'Boolean')
-Val indicates whether the check passed of failed
Pseudocode example:
//Model Number Check
check# = 0;
resultBOOL = ModelNumberCheck();
SetDimensions("Step.Result.Val", 0, "[0]", check#);
SetValBoolean("Step.Result.Val[check#].Boolean", 0, resultBOOL);
if(resultBOOL == FAIL)
Note# = 0;
SetDimensions("Step.Result.Notes", 0, "[0]", check#);
SetDimensions(Step.Result.Notes[check#].String, 0, "[0]", Note#);
SetValString("Step.Result.Notes[check#].String[Note#]", 0, "Model Number Check failed");
Note# = 1;
SetDimensions(Step.Result.Notes[check#].String, 0, "[0]", Note#);
SetValString("Step.Result.Notes[check#].String[Note#]", 0, "Model Number = 1234");
//Serial Number Check
check# = 1;
resultBOOL = SerialNumberCheck();
SetDimensions("Step.Result.Val", 0, "[0]", check#);
SetValBoolean("Step.Result.Val[check#].Boolean", 0, resultBOOL);
if(resultBOOL == FAIL)
Note# = 0;
SetDimensions("Step.Result.Notes", 0, "[0]", check#);
SetDimensions(Step.Result.Notes[check#].String, 0, "[0]", Note#);
SetValString("Step.Result.Notes[check#].String[Note#]", 0, "Serial Number does not match expected");
More Checks
As you can see above, the "Step.Result.Val" array is redimensioned for every check. The "Step.Result.Notes" array is only redimensioned when a note needs to be added for a failing check. If the entire step executes and no check adds a note, the sequence is fine. If every check fails and therefore every check adds a note, the sequence is fine. However, if there are any gaps (e.g. check 0 adds a note, check 1 does not add a note, and check 2 tries to add a note), the sequence will stop. If I add blank notes for every check that would otherwise not have a note, the sequence completes, but the report shows the blank note.
Also, the exact code that is causing these problems runs fine on our old systems (TestStand 1.0). I hope that I clarified the problem and thanks again for the help.

Use of type libraries and custom data types in TestStand 3.1

Consider the following example in CVI 7.0:
#include <cvidef.h>
typedef struct
    int                         t_err;
    unsigned int                err_flags;
    int                         err_code;
    char                        err_msg[1024];
} TEST_ERROR;
int DLLEXPORT DLLSTDCALL   NfctConnect (int iPortType, int iComPort, int iBaudRate, TEST_ERROR * tstError);
I want to call this function from TestStand 3.1 using the CVI Standard Adapter.
I created a function panel from the header file then I generated a DLL that contains the type library as an embedded resource. Using OLE/COM object viewer I can confirm that the definitions are correct. In TestStand however, all basic types are recognized but the structure is rejected as not being a TestStand type.
However, a C structure is supposed to be assimilated as a container in TestStand. Do I have to manually create a custom data type in TestStand to match my C structure or TestStand can automatically create the container based on the information in the type library (because this information is available it won't be difficult for TestStand to do this automatically)?

Hi Spoli,
At the current time the only adapter that gives you the option to
automatically create a container for a given parameter is the LabVIEW
adapter. In your case you will need to manually create the container
that matches your C struct. I apologize for the inconvenience.
One thing you can do to see this feature in future versions is make a Product Suggestion on our website. Our R&D engineers are always looking for good feedback.
Have a good one Spoli,

How can take a Custom Data Type in TestStand and create a LabVIEW DataType?

I am using LV 8.2 and TS 3.5.
I have an existing Custom Data Type in TestStand and I want to make a LabView Type Def. The TS DataType contains 11 elements: a Visa Resource Container of 2 elements (String, DeviceName and Number, Session), 9 Numerics and 1 String Array. For Backwards compatability, I cannot modify the TestStand DataType.
Thanks,
Jean

Hi Goldee,
You should be able to do that. It's a two step procedure.
1) Creates in LV a custom datatype that maps 1:1 yours TS datatype.
2) Go in the TypePalette in the properties of yours TS Datatype and check into LV Cluster Passing Menu'. Here you can Connect a specific Field of the TS datatype to a Specific Label of the corresponding LV datatype. Once you've done it the TS datatype will result modified, I mean "starred" but the change you applied should not impact the datatype structure itself only the way you pass it to LV.
Have a good day

Where to define new custom data type ?

Hi,
In the past (TS 3.5) I've created our own custom type palette file which has been used
to store new data types and then passed the file to other colleagues. The file would be
stored in the ......\Program Files\.......\User area.
My question has arose because we are now using TS 4.1/4.2 which no longer has separate
NI and User directories in \Program Files.
Because I now want to edit an existing custom data type, I find that our custom type palette has
fallen by the way side, forgot about.
Even though I can see the custom data type definitions within sequence files that employ
the custom data types, which means I can modify them locally, I intend to return to
a custom type palette, i.e. global definition.
What is the relationship between data definitions in a custom type palette and the custom data
type definitions within a sequence file ?
When does a palette file update a sequence file ?, which takes control in the event of conflicts ?,
is a palette file actually necessary if separate sequence files using the same custom data type
can update each other ? What is good practice when defining custom data types ?
thanks,
Gary.
Solved!
Go to Solution.

Hey guys,
This is an very interesting thread, and I whole heartedly agree with the advice given so far. I simply wanted to offer some additional advice on type conflicts - which with further answer the initial question regarding which type definition takes precedence in the event of a conflict.
It is important to note that TestStand uses type Names and version numbers to identify the different types. It is also important to note that when you use a customer type definition within a sequence, the sequence file (.seq) which houses the sequence will retain a copy of the type definition. This makes distributing sequence files much easier. However, it also opens the door to potential type conflicts.
TestStand only allows one uniquely named type to be loaded into memory at any given time, so it uses the versions number of the type to attempt to automatically resolve these conflicts. For example, TestStand can be setup to load whichever type has the highest version number (note that this can be changed via the Preferences tab of the Station Options dialog box).
All of this information and more can be found in the following tutorials...

How do I pass a custom data type to a dll in TestStand?

I need to add a new feature / function to an existing TestStand program. The original program uses a custom data type for the LabVIEW VISA (serial com) reference, as shown below. I want to use the StationGlobals.VISA_Ref in my call to the dll.
The VI prototype is shown below. The VISA Ref In is a basic VISA reference control (serial comm) from LabVIEW. Nothing special.
I am stuck at trying to figure out how to configure the VISA Ref In parameter... I've searched this forum and the only posts which seem close to what I am attempting to do did not have any responses... I hope to be "luckier"..

What you are describing is similar to this, right? http://digital.ni.com/public.nsf/allkb/22BF02003B4588808625717F003ECD67
I tried something similar to what you described.... unfortunately, TestStand is holding on to the serial port and has not let go yet... Which causes a run-time error within the LabVIEW code (dll) because the resource it is trying to use (COM port) is not available...
I will check the code and see whether they use the serial port after it gets to the new feature... Otherwise, I may close the port, use it within LabVIEW (dll), close it and then re-open within TestStand... That's why I wanted to pass the reference directly... Although, the way you describe it, it may be possible to pass that same reference indirectly and get the dll to work without having to play with closing / opening references. I'll explore that tomorrow.
Thanks.

Custom Date Types

Hi,
I have created a few custom date types and added them to the date profile.
The date profile is assigned at the item level Category.
I can view these custom dates in the backend in t-code CRMD_ORDER under the "Service Data" tab, however, these are neither available in the WebUI in the "Service Level Agreements" assignment block nor in the "Dates" tab.
I want these to be available in the "Dates" assignment block.
Please guide.
Thanks,
Rinkal.

Rinkal,
In customizing, you can assign screen areas for a date type/ duration, when you add them to a date profile. Have you maintained that?

Share the customed data types between sequence files

Is there any way to share the customed data type , ex. containter, between the sequence files?
I created some containters, ex, datatype1 in the File1.seq. The other
file File2.seq calls a subsequence which pass the datatype1 as
parameter. But now I have to copy the datatype1in the custom data type
section in the File2.seq. I didn't find the way in the teststand , when
I want to insert a container which is from another file.
The disdavantage of this way is , if the data type is changed, you have to change the data type in both files.
Thanks
Sundog

You can add the data type to the station globals. Then they would be updated for each sequence that uses them.
Open the stations globals and change the view to Global Types. Add your type there.
Message Edited by paulmw on 01-10-2007 01:01 PM
* I noticed that I can't find the type when tring to create a local varable using the above steps, so it looks like this won't exactly work.

Howto deploy custom data types

I have created a custom data type and added this to my type palette in a new .ini file.
When I distribute my application is it necessary to distribute this .ini file? If so, where does it need to be copied to? Also, what (if any) TestStand API calls do I need to make to register this new custom data type?
Thanks,
Jason

Jason,
You do not need to distribute the type pallette.
A copy of your custom data types should be included in the sequence file types, so the sequence files using the custom types should work fine.
The only reason you want to distribute a type pallete is to make your custom data types available to other developers. In that case you only have to copy your file to the other computer and save it in the same location it is located in your system (TestStand\Components\User\TypePalettes).
Hope it helps.
Best Regards.
Antonio Lie.
