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

How to access the global data in user exit.

Hi All,
How to access the global data in user exit.
the question is that when we were writing a code in the FM. i need to read data from the standard program like newly created documen and this document number need to be accessed in my program.
this document number is not imported to the FM i needed to access for frther proceed.
Thanks in advance.

Hi,
See the below PDF file by Jeff Goldstein. There you can find all the details about accessing data outside of the exit.

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

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.

* 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.

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

You can apply similar concept if you want to use stored procedure.
If you still get problems, post the type that you have created and the error you are getting.

How to access PL/SQL data types through JDBC

Hi,
We have stored procedures written in PL/SQL. These stored procs take both IN and OUT parameters. The parameter types are both regular datatypes like NUMBER, VARCHAR etc. So far so good. I know how to handle these data types.
Some of the stored procs also use parameters that are defined as composite data types like %ROWTYPE or %RECORD. How would I set the values of these data types? Can I use the oracle extension - support for Oracle Objects to accomplish this. If so please let me know with an example. If not any other suggestions or help will be greatly appreciated.
Thanks

JDBC (and SQLJ) only support SQL types as stored procedure arguments, not PL/SQL types.
If your stored procedure uses a PL/SQL-only type, such as BOOLEAN, record types, or index-by tables, then you cannot call it from Java (or, for that matter, from other languages as well).
There is one exception: scalar index-by table arguments have been supported since JDBC 8.1.7 in the JDBC-OCI driver (refer to the JDBC manual for specifics).
One workaround is to create wrapper PL/SQL stored procedures that take SQL arguments and convert them to PL/SQL -and vice versa- and call the original PL/SQL stored procedures. For example, a record type could be exploded into individual arguments, or it could be converted into a SQL object type, index-by tables could be represented as SQL collection types, etc.
You can find a small example of this in the back of the JPublisher manual, where an example is given how to call a PL/SQL stored procedure that takes BOOLEAN arguments.

Worse you added new lines that have new errors.

If you aren't willing to post sample code why should we? The code you posted won't even compile so it can't possibly be the code you are actually using that purportedly has an error.
exception ....That is invalid code as you undoubtedly know so what does it accomplish by adding it other than making people think your actual code was removed. But that means that the code you removed could have a problem in it that we can't see. And that means we have no hope of finding your problem because we can't see all of the code that might be causing it.
>
Please ignore spelling mistakes.
>
We can't ignore them if the code you post won't compile with them in it. The word 'procedue' you provided in the original question isn't a spelling mistake; it's because you did not cut & paste your actual code. It means that instead you manually entered text that is not code you are actually using.
If you really want help with your problem you need to post the code that you are actually using and that is giving you the problem you are reporting.
>
l_text varchar2(1000):=null; -- i have built some dynamic whee clause in this variable

But are you using NULL for this value when you run your test? If not then maybe the problem is in the value that you are using. How could we possibly tell when you don't post what you are using?
Post the code you are actually using. If you can't do that for proprietary reasons then modify it to remove the sensitive code. But the code you post has to be the code you are using and the code that is giving the problem.

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!!

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

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.

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!

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...

Customized data type

i tried to make a simple Dynamic Invocation Interface client sample. how do i set input and output a customized data type and how do i invoke the method that uses the customized data type?thank you.

bump...Any solution to this problem? I am also facing the same issue.

What's going on with re-ordering custom data types?

OK, I can't make heads or tails out of this one:
I've got a bunch of custom data types in my own typedef file (and it's part of my type palettes).
I open up my types browser, select my type file, go browse to the "custom data types" section.
I want them in a different order so I can better understand them.
(actually I select the one below it (TekTimestamp) and try dragging it up and down the list. anywhere I go I get the circle with a cross through it saying I can't drag it here.
OK, give up on that one.
Then I'll grab TekSimulateMode typedef
Try dragging it around, and I get the nice black line saying I can drag it somewhere else -- looks kinda like this:
Notice I dragged it only one spot down, and the item I dragged it across is used in exactly the usage locations, and neither has any nested typedefs (they are only containers of primitive boolean/string). Also notice that it and everything I dragged it across is owned by this type file.
Once I let up on the mouse, I get this warning message popping up:
What's up?? Why can't I change the location of the first typedef (ordering) within the file, but I can for the second??
Why do I get this dialog when I move a typedef within a file that already owns it??

Oop. My bad. I was so eager to help you out...
I know it has to do with the Usage column. Since you are changing your Station Globals.ini by dragging them around I think the warning is from there. I know that once you have instances of them then you are now changing that data type for all those locations. That's why you can't delete them if you have an instance. It won't (or shouldn't) affect anything by moving them other than you may now have to save your station globals and sequence files again. Not sure if it revs the version or not, it doesn't look like it did on mine.
As for the one that won't move? Not sure on that one. I've never seen that. Possible some instance is restricting it.
Hope this helps some,
