Passing accumulation data from dll

Hi Sir/Madam,
I have tried to search the NI forum, but could not find something that can solve my queries.
I have to interface a sensors that provide with a dll. There's no problem with interfacing most of the function, but only this particular one(see attachment).
It require a passing of pointers of "accumulation" of struct.
Hope someone can help me.
Your help is greatly appreciated.

There a few tools that you can use. You can open the example finder and search for a VI called Call DLL. Once you run this application, it shows the mapping of all LabVIEW data types to external data types and how they are used. There are also examples. Depending on your version of LabVIEW, you can go to Tools >> Import >> Shared Library (dll)... and pass it the header file for the DLL and LabVIEW will automatically create wrappers for the functions. If you know the data type that the pointer is referencing, you can create an array of those data types and feed that into the Call Library Function Node.vi.

How to pass the data from a input table to RFC data service?

Hi,
I am doing a prototype with VC, I'm wondering how VC pass the data from a table view to a backend data service? For example, I have one RFC in the backend system with a tabel type importing parameter, now I want to pass all the data from an input table view to the RFC, I guess it's possible but I don't know how to do it.
I try to create some events between the input table and data service, but seems there is no a system event can export the whole table to the backend data service.
Thanks for your answer.

Thanks for your answer, I tried the solution 2, I create "Submit" button, and ser the mapping scope to be "All data rows", it only works when I select at least one row, otherwise the data would not be passed.
Another question is I have serveral imported table parameter, for each table I have one "submit" event, I want these tables to be submitted at the same time, but if I click the submit button in one table toolbar, I can only submit the table data which has a submit button clicked, for other tables, the data is not passed, how can I achieve it?
Thanks.

Not able pass the data from component to other component.

Hello All
I am not able pass the data from component to other component.
I have done like this.
1 Main Component (Parent component ) having below two child components.Embeded as used components.
2)     Search Component and Details Component
3)     In the Search Component having buttons, Say : Button u201CXu201D on click of button I am navigating to Details component view through FPM.
4)     When I am clicking above button u201CXu201D raising the event to call the parent   business logic method, there I am getting Structure with values and binded this structure to the node and Mapped this node to the Details component interface node. FYI : I kept the debugging point Structure is having data , I had set static attributes table to node instance.
5)     In the Details component node data is not coming mean empty.
Thanks in Advance.

Hi,
When you use input Ext. check that the parent component should not be used as used component in child component.
Only in the parent component the child components should be used as used components and the usage has to be created for the
Child Components and the binding of the Node should be done from comp. controller of parent component to child node
by which you will be able to see double arrow against the node.This should work

How to pass realtime data from a sub vi to a calling vi?

I'm trying to pass some data from a called (sub) vi to the calling vi,
while the sub vi is running. I've tried passing to a global, but the
calling vi doesn't show the results until the sub vi has completed
execution. I understand why this is happening, I'd like a method, if
one exists, to work around it.
Thanks!
Bill

You've done several things incorrectly. First, the subVI has a while loop that terminates with a front panel Boolean. Since you don't make the front panel of the subVI visible, the subVI just runs with no way to stop it. When you call a subVI, execution passes to the subVI and the calling VI is paused. Since the subVI has no way to stop and return to the main, the while loop in the main is not running and reading the global variable. If you were to drag the subVI outside the while loop, then you would see the global update. You still would need to make the subVI visible in order to be able to press it's stop button. Of course, with the subVI visible, it's front panel is showing the value getting updated and there's no reason to have a global in the main anyway.
If you want to have a subVI remain hidden, you can't use a while loop with a front panel control that's needed to stop it. Well, you can but that gets kind of complicated. If you do have a subVI and want to update an indictor with a global, the reading of the globabl should be done in a separate while loop. To keep the update in the same loop, don't use a global. You can create a reference to a front panel indicator and pass that to the subVI. The subVI writes to the value property. Here's a real simple example of that in 7.0.

Hi
you can use function module
data   ls_input_container TYPE swr_cont.
data   lt_input_container TYPE TABLE OF swr_cont.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
    EXPORTING
      task            = ptask
    IMPORTING
      return_code     = lv_return_code
      new_status      = lv_new_status
    TABLES
      input_container = pinput_container
      message_lines   = lt_message_lines
      message_struct = lt_message_struct.
where you pass the data in imnternal table "pinput_container" as
ls_input_container-element = 'KUNNR'.
ls_input_container-value = ls_skna1-kunnr ."wd_this->lv_kunnr.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'CLUSER'.
ls_input_container-value = lv_cluser.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'BUKRS'.
ls_input_container-value = lv_bukrs. " youe value as per requirement.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'VKORG'.
ls_input_container-value = ls_sknvv-vkorg. " youe value as per requirement
APPEND ls_input_container TO lt_input_container .

APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'SPART'.
ls_input_container-value = ls_sknvv-spart. "youe value as per requirement.

HOW TO PASS THE DATA FROM SELECTION SCREEN TO STANDARD TRANSACTION?

HI,
HOW TO PASS THE DATA FROM SELECTION SCREEN TO STANDARD TRANSACTION?
thanks,

By selection screen, what do you mean? There is no selection screen in WDA as there was in classic dynpro. Do you mean you are using the Select-Options reusable component? Are you wanting to call a standard transaction via ITS - SAPGUI for HTML? Please provide more details to your question.

How to pass a data from child window to parent window

Hi,
I have a jsp page with two hidden fields and a button, On clicking the button a popup will come out. There are two combobox in the popup and a search button. After putting a value in the comboboxes,if I click the search button, I need the datas of the combobox to pass to the parent's hidden fields then I need to do a data base search with that values of hidden fields and display the result in the parent page.
I could I solve this problem, Please help, Its urgent.
Thanks and Regards
Rajib Sharma

I think that you can use the JavaScipt as follow to pass a data from child window to parent window
<HEAD>
<script>
function passData(){
opener.form1.test1.value=form2.test2.value; //pass the value of test2 to the parent's test1
window.close();
</script>
</HEAD>
<BODY>
<form name=form2>
<input name=test2 type=text>
<input type=button onclick="passData()" value=CLOSE>
</form>
</BODY>

Pass Key date from Sender to Receiver Query

Hi,
We have a requirement to pass key date from the sender query to receiver query.
In our sender query we derive the key date based on the calendar month value entered by the user on the variable screen and this is used to determine the hierarchy structure to be used for report.
The user have the option to drill down to detailed query (using RRI) from the context menu option. We would like to use the same key date in the drill down query as the sender query. The drill down query does not have any variable selection.
In RRI settings I can not see the way to pass on the key date.
Any help is appreciated.
Thanks,
Ankit

Hi Suman,
Yes, we do not have variables in the receiver query as we expect the settings in RSBBS to pass the filter values to the receiver query and which is being done consistently.
The problem is that we do not have any option to pass key date. If required we can add a customer exit variable but how will it work if the user does not want to enter the variable values for the drill down report.
Thanks
Ankit

Pass transaction data from an InfoProvider to the BPC within BW

Hi Gurus,
I need to pass transaction data from an InfoProvider to the BPC Real-Time InfoCube, but I need to do from BW, and not from the BPC Excel interface.
The reason is that I want to make the whole process in one step, and at the beginning of the process the end-user has to introduce some parameters in the BW, as we are launching the process chain from a transaction.
Therefor I copied the process chain /CPMB/LOAD_INFOPROVIDER and tried to introduce the different parameters that are normally delivered by the prompt in the excel interface.
Can anybody help? Does anybody know what parameters for each process type have to be introduced, in what form and if all the process types are needed?
Making it with a normal BW transformation is also not an option, as we don't want to change from plan mode and stop people from planning.
It is very important for my end user to do everything in one step, without having to enter the BPC Excel interface.
Thanks in advance.
Cheers,
Àlex

Hi Frank,
I have checked and we have many processes in SM50 available for the job to use. Sometimes there are no other jobs running in the BW System except for the 2 jobs but still the 2nd job waits for the first to finish.
I did another check on transaction code SM58 in BW System. Here it shows all the transactional RFC queues that is being generated by the 2 jobs. I saw that only TRFC queues are able to execute at one time. I am not sure if this is the problem but is it possible to set the number of queues that can be executed at one time to more than 2? If yes, where can I find such a setting?
This is quite urgent as this problem causes all my jobs to end very late.
Thanks.

How to pass csv data from file into DLL using TestStand

Hi,
We have data files which are of CSV format. Each row contains
about 9 items of data, and have about 5 rows of this data (ie, 5
test points) :
eg
TErrAdd1,UUT,UUT,STM1E,AU4/FR,PRBS23,BIT,10,60
TErrAdd2,UUT,UUT,STM4O,AU3/UNFR,PRBS15,B1,20,60
TErrAdd3,UUT,UUT,STM16O,AU4_16C/UNFR,PRBS9,BIT,7,60
TErrAdd4,UUT,UUT,STM0E,AU3/UNFR,PRBS20,B2,5,60
TErrAdd5,UUT,UUT,STM64O,AU4_4C/FR,PRBS11,B1,6,60
What we want to do is to be able to directly pass each
row of data to a C/C++ DLL. The DLL fn accepts this
data as a vector of strings.
eg.
void DLLTestFn( vector const & configData )
However, we can write a wrapper for the DLL as I don't
think TestStand will know about vectors.
We don't really want to have to hardcode individial references
to each item of data in TestStand. Is this possible?
Just read in a row from a data file, and sent it direct
to the DLL?

Hi Richardi,
the principle is quite simple, however, you still need to use a programming language to make the initial file read.
Once you've done this, you could have it as an array of strings, and pass this directly to a wrapper DLL, which would then pass the data into a string vector.
Look up the examples\AccessingArrays\PassingArrayParametersToDll\AccessingArrays.seq
to see how to do this without passing the sequence context.
If you've read in the details into a container type structure already, then I've made an example which demonstrates this principle and what you'll need to pass it to a vector. (Similar principle can be used to fill in the container when you read the file in the first place.
You cannot go directly to a vector, since TestStand doesn't understand them.
Vector classes are difficult to export polymorphically from a DLL since the template class doesn't export, and needs specifically defining. This is what I'm assuming you're ultimately trying to do. (see ref :
How to Export STL components inside and outside of a class
I've used VIsual C++ 6 and TestStand 3.0
Please let me know if this helps to answer your query.

How do you pass the data from a SBO process to a crystal report laout

Hi Everyone
Can someone please assist or direct me to documentation that could be of help.
I do production orders in SBO.
I have a crystal report that I have imported as a layout to print these production orders.
The report was developed the normal way, linking to the tables and returning data(all data for all production orders ever done)
The production print option is set to make use of this layout.
What I would like to see is that when I create production order 12345 and click on print preview I get the data of the mentioned order only displayed in my crystal layout(that is set to default)
What I get however is all the data from the tables.
Where am I going wrong. With my design already or is there a different way to pass the data to my report/layout direct from my SBO production order screen
This is quite urgen
Regards
Burger

Hi All
The solution i was looking for is:
In Crystal create the parameter called DocKey@
This is recognized by sap and the active document number is passed to the report layout.
In crystal itself also do a filter {<Table>.<Column Name>} = {?DocKey}
So simple once you know how.
Hope this help someone else that is as stuck as I was.

How to pass the data from a pop up window to the parent window

Plz reply its urgent
Thanks and Regards

Thanks for the reply
But it not worked
I have a jsp page and the popup is also a jsp page the data that is passed from the popup window to the parent must be send to the server from the parent window to get a data from the data base as search result. Its of no use to get it as js data
