How can I get command values from a VI executed by reference ? NEWBIE

Hi,
I'm running a sub-vi in a "Secondary Front Face" (excuse for the
translation if not correct, I'm working on a French version). In order
to run this VI, I pass a reference. All is working fine but I don't
know how can I get the values entered by the user in this VI ?
Actually I run a main VI wich contains a "Secondary Front Face" (this
SFF is contained in a tabbed pane). In my diagramm, I pass a reference
to another VI (by the name of the file *.vi). If my user enter a word
in a text field, I would like to be able to get it in my main app.
Thanks for your help.

Hello,
You might take a look at the following tutorial for more information about calling a VI by reference. It's got some great visuals and examples.
Tutorial: Calling a VI by Reference
You might also consider just calling the secondary VI as a simple subVI, if you can spare the memory space when loading the main application, as this is the easiest way to input and output VI values.
I hope this helps! Please let me know if I can be of any further assistance.

How can i get all values from jtable with out selecting?

i have one input table and two output tables (name it as output1, output2). Selected rows from input table are displayed in output1 table. The data in output1 table is temporary(means the dat wont store in database just for display purpose).
Actually what i want is how can i get all values from output1 table to output2 table with out selecting the data in output1 table?
thanks in advance.

You could set the table's data model to be the same:
output2.setModel( output1.getModel() );

How can we get the value from the af:selectInpuText component

Hi,
I have to get the value from af:selectInputText component when we click on af:selectInputText mirror icon.
Edited by: durga on Aug 17, 2009 1:59 AM

That was not what I was looking for. Because it would give null as value in my scenario. But I have solved that problem by passing the value of element in href. as window.open('www.sun.com?text='+document.getElementByID('req').value,'Blank',standards);
Thanks for your comment.

How can i get currency values from flatfile to function module

Dear All,
           I have to take currency values from flat file and i have to assign those flat file value to function module .
Eg: "Convert_to_local_currency". I need technical code how to calculate those amount in work area and how to assign those amount value function module.
          I need sample program for currency conversion from flat file to function module. My requirement is based on flat file amount i have to calculate in work area and assign those work area to function module.
With Regards,
Baskaran

Hi Satish or Baskaran,
First conform in which format the flat file is present, as abhi mentioned if it is there in notepad
try to use F.M GUI_UPLOAD as shown below...
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
FILENAME = 'C:\Desktop\rpf1.TXT'
TABLES
DATA_TAB = ITAB.
Now loop at ITAB Into Work_area and press the respect currency fields which you want and in the same way
if the file is in EXCEL format use F.M ALSM_EXCEL_TO_INTERNAL_TABLE
CALL FUNCTION 'ALSM_EXCEL_TO_INTERNAL_TABLE'
    EXPORTING
      filename = P_FNAME
      i_begin_col = 1
      i_begin_row = 1
    TABLES
      intern = ITAB
LOOP AT ITAB INTO WA.
CALL FUNCTION 'CONVERT_TO_LOCAL_CURRENCY'
        EXPORTING
          foreign_currency = wa-waers
          local_currency   = wa-waers
           IMPORTING
          local_amount     = tvals-gross.
    ENDIF.
endloop.
And as mentioned loop the records into work area and process the currenct field which is present in the
ITAB according to its field name. And make sure within the loop you call your function module.

How can i get the value from a HTML Form

hi,
I am using HTML form (logfrm). there are userId field,password field, submit button,reset button, and a link.
when i click on the link, it should fetch the value of userid.
How it is possible?
AE

use jsp:
which lets you embed java statments in your html -so you when you click on the link you can use request.getParameter("userID") to get the userid.
Ideally with html forms use a combination of jsp and java beans, where the fields in the form are also fields in your java bean, which you can access through setters and getters.
google for some jsp tutorials.

How can I get multiple values from form as a list ?

we designed a form , and there are some attributes designed as checkbox , the data in the form is like following :
    <xml ......>
            <party>11</party>
            <party>22</party>
            <party>33</party>
    </xml>
Is there any easy way to get the parties' data from the xml into a list predefined as a process varible ?
Any help is appreciated !

You woudl use a setValue service and use xPath expressions to extract the individual party nodes from the inbound XML and then populate the list with these values.

How can I get the value of "Warehose" column in a form

How can I get the value of "Warehouse" column in the form below (I mean what table that contain this value):
Production Supervisor >> Batches >> (Button) Material Details >> (Button) Line Allocations
Well, for more clearly! My problem is I must have the Unit Cost of Items, so I've got it in the cm_cmpt_dtl (table), but if I want to, I must create a relation that require 2 filed, they're Item_ID and Whse_Code.
There's no problem with Item_ID, but Whse_Code seem to be the Mission Impossible (hix, I hate that film!!!!)
I wonder if It was right to post this topic here. But anyway I just post my question here, hope I could get some help.

wow, many, many, many.... and many thanks!
Just add a tiny modify to check out the Batch_type
doc_id = (select batch_id from gme_batch_header where batch_no='&batch_number' and batch_type = 0)
Because the batch_no can be duplicated as we also create Batch and Filrm Planned Order.
Many thanks for your support!

How can we get the value of the key field in a custom data model using governance API?

Dear Team,
How can we get the value of the key field in a custom data model, to be used for manipulation of the change request fields using governance API?
Any kind of help would be sincerely appreciated.
Thanks & Regards,
Tushar.

Hi Michael,
Thanks for direction. Let me give more context on this as I'm interested to get more details..One of the issue was to read cross entity field values on UI based on user action and set other entity field behaviour...It is similar to what is being posted here.
For ex: Reading MTART from Basic Data UIBB in MM MDG UI and set the field properties in some other custom entities say ZZETEST. This cannot be done using UI BADI as it only supports single entity at a time and not cross entity. So alternatively we found a solution where we can enhance existing PLMB feederclass cl_mdg_bs_mat_feeder_form by reading the model and the entity as needed as it it proved that it supports cross entity UI field behaviours and so business requirements.
This is a workaround for now.
So the question is How do we achive it using governance API for cross entity field behiaviours.?or what is the right way doing this.
Can we do that using governance API and its' methods?
In the Governance API doc you provided below has referring to below external model as part of gevernance API.
The active or inactive data (before or during the derivation or the check) can be read
with the external data model interface IF_USMD_MODEL_EXT with the method READ_CHAR_VALUE and
the corresponding READ_MODE parameter. To avoid unnecessary flushes (derivations), the NO_FLUSH
parameter should b
e set to ‘X’.
Thanks

I can not get link-value from af:tree.

Hello.
I use jdeveloper 10g.
I can not get link-value from tree.
I use following code:
<f:facet name="nodeStamp">
<h:panelGroup binding="#{backing_dialogDic_dic_ETS.panelGroup1}"
id="panelGroup1">
<h:outputText value="#{item.vidNum} #{item.vidName}"
binding="#{backing_dialogDic_dic_ETS.outputText1}"
id="outputText1"/>
<af:commandLink
binding="#{backing_dialogDic_dic_ETS.commandLink2}"
id="commandLink2"
action="#{backing_dialogDic_dic_ETS.returnObject}">
<af:setActionListener from="#{item.idVid}"
to="#{processScope.ETSId}"/>
<af:objectImage source="/images/icons/10.gif"
shortDesc="Выбрать"
binding="#{backing_dialogDic_dic_ETS.objectImage2}"
id="objectImage2"/>
</af:commandLink>
</h:panelGroup>
</f:facet>
</af:tree>
//in java bean:
public String return_Object() {
Object ob = JSFUtils.getManagedBeanValue("processScope.ETSId");
System.out.println(o);
return null;
In console I see null.
How I get this value???
I can get this value if i use treeTable instead of tree.
Thx, Dema.

Hi,
not that I think it matters, but the processScope is not a managed bean but a memory scope. So if
JSFUtils.getManagedBeanValue("processScope.ETSId");
assumes a managed bean then this may be incorrect as most likely there exist no managed bean with this name. You should be able to access the process scope from AdfFacesContext.getProcessScope(), which then returns a Map, which you call get("ETSId") on

How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system. Not enough memory to upgrade.

You can't. iCloud is not for general file backup from a Mac. It's for backup up and syncing data between mobile devices and and Macs and The following is from this Apple document: iCloud: Backup and restore overview.
iCloud automatically backs up the most important data on your (mobile) device using iOS 5 or later. Once you have enabled Backup on your iPhone, iPad, or iPod touch .....
What is backed up
You get unlimited free storage for:
Purchased music, movies, TV shows, apps, and books
Notes: Backup of purchased music is not available in all countries. Backups of purchased movies and TV shows are U.S. only. Previous purchases may not be restored if they are no longer in the iTunes Store, App Store, or iBookstore.
Some previously purchased movies may not be available in iTunes in the Cloud. These movies will indicate that they are not available in iTunes in the Cloud on their product details page in the iTunes Store. Previous purchases may be unavailable if they have been refunded or are no longer available in the iTunes Store, App Store, or iBookstore.
You get 5 GB of free iCloud storage for:
Photos and videos in the Camera Roll
Device settings (for example: Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts)
