Trying to get export value from combo box

Using the "Custom Keystroke Script" for a combo box:
// This works but gives the current face value
if( event.willCommit )
app.alert(event.value);
// This works but gives the previous export value
if( event.willCommit )
app.alert(event.target.value);
What I need is the clicked items' current export value as soon as it is clicked.
What am I doing wrong?

Sorry about that. I posted the question and then realized I should have just used the same thread.
Any way, I tried your code and it does not show the current export value. It shows the previously selected value.
Example:
When I click item 2 it shows item 0
Then I click item 4 and it shows item 2
Then I click item 7 and it shows item 4.. etc.. (see the pattern)
What I need is the value from the item I'm currently clicking on.
If I click item 2, I expect to see item 2. etc..
Thank you for your patience in answering this!

While selecting value from combo box in one frame, based on the selection..

Hi friends,
can someone help me out on a issue as it follows:-
iam developing an application where Iam using xsl,html,javascript and xml.
There is no existense of Database at all. data is read from xml.
now,
In a window there are 3 frames. In the 1st frame combo box is there.
Based on the selection in the combo box data will be displayed in the 2nd frame.
now onchange or onselect methods not giving the expected result.
actually,in the the xsl which is having 3 frames,the 1st and 3rd frame
calling src="abc.xml" and src="abc.xml"which are static.
but in the 2nd frame the data need to be changed dynamically.
I have given frame name="frame_ExchangeDetails2" rows="3%" src="cc_marketWatch_02.xml"/>
usually data dynamically comes from database.but here i have to refer xml file
something like [window.href.location="abc.xml"]
but the problem is when you refer supose:-
<frame name="frame_ExchangeDetails2" rows="3%" src="cc_marketWatch_02.xml"/>
the frame is having static page,though there are functions in javascript which are called in onload and onchange.which are not working.
I have tried putting if condition like:-
if(document.abc.fieldname.value=='6'
{ window.location.href = "cc_custLookUpData-mobileno.xml";
so that it could go to the repective page.
but it is not working.
so what should i do if I select from combo box in one frame and based on the selection xml/html page will be displayed in the 2nd frame.
if anybody has google account i can forward the zip file so it will be easier to understand.
Regards

If you have rights to modify tabular model then, you can create a measure in your Tabular model which returns previous week and then use this measure in Pivot Table.

Swing: when trying to get the values from a JTable inside an event handler

Hi,
I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
I put two buttons (plus labels) and a JTextField . The buttons have the following role:
One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
I would thank you very much for the help.

You could use associative arrays, or even better to use XML
with e4x syntax. See these FB3 help topics:

Getting values from list box

i am populating a list box with Id's and names from a database and im trying to get the values from the list box depending what the user chooses, i.e if they choose the first choice in the list box the value i want to put in a variable is 1, etc
here is the code for the list box, please help
<select name="lstFilm" size="1">
          <%while (result4.next())
               {%>
<option value="<%result4.getInt(1);%>">
<%out.println(result4.getString(2));%>
</option>
               <%}%>
</select>

String[] lstFilm = request.getParameterValues("lstFilm");
Of course, it'll only return selected values. It'll be whatever the option values are.

HOWTO Get the text of "combo box" and "labe" controls with JavaAccessBridge

HOWTO Get the text of "combo box" and "labe" controls with JavaAccessBridge.
Please help,
I'm trying to use the Java Access Bridge (JAB) 2.1 to get the text in Java Applet controls. I've been able to use the sample code in AccessInfo.cpp sample that comes with JAB to get text from "text" controls in a Java Applet. To clarify, I am referring to the "role" in the AccessibleContextInfo struct being set to "text" or "combo box" or "label".
The problem is, when I use the AccessInfo.cpp sample to get text from a "combo box", the accessibleText data member comes back as FALSE, and thus any of the JAB text functions like GetAccessibleTextInfo fail to get any text information from "combo box" or "label" controls.
I've also tried GetCurrentAccessibleValueFromContext on the "combo box" and "label" controls, but the text returned is empty.
Can anyone help?

I have new information in regards to this issue. A contact from Sun did get to me in email and relayed that that "label" objects store their text in the "name" data member of the AccessibleContext structure. This was a big help.
But I'm still stuck trying to get information from "combo box" and other controls, like "push button". The contact said, the Java Access Bridge does not provide all the information because it is already implemented by other interfaces like AccessibleComponent, AccessibleAction, or AccessibleSelection. The contact did not allude to whether these opther interfaces can be used along side the Java Access Bridge or not. So, I'm left a step closer to the goal, but still stuck without the full solution.
Can one take the Java Access Bridge functions, like say those used in the Ferret sample, and close the gap to get text back from "combo box", "push button", and other controls by using some other API in conjunction?

Hi everybody
I got it workin by making this change to my code:

         jLabel1.setText(tulos1.toString());

VS2008 C# cannot get return/export values from SAP (one way connection yet)

Hello Experts,
I have successfully established connection to SAP by using Visual Studio 2008 (C#) and web services:
-     I am able to login into the SAP-System with my C#-Application
-     I am able to call and run functions with my C#-Application
-     I am able to passing over vales from my C#-Application to the function module (importing variables = ok)
The problem I face now is getting return values from the function module (getting values of the exporting variables). I just have no idea how to call the u201CResponse-methodu201D correctly in C#.
I think the problem is hided in the wsdl-xml-file.
Here are my codes (only C# codes are really relevant) I post them step by step:

Getting the Values from a Tiled View

Hi,
I have a TiledView and I have checkbox in the tiled view. I am trying
to get the values of the checked boxes.
I have coded like this.
Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
if I see the links.length i get only one. In html If I see the code
it appends the TileIndex in brackets. If I replace the TileIndex with
0 in all the fields in endCbSystemUrl method I get the correct values.
In the TiledView beginDisplay() method my code is like this.
if (getPrimaryModel() == null) throw new ModelControlException
("Primary model is null");
super.beginDisplay();
resetTileIndex();
pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
getParent();
((DatasetModel) getDefaultModel()).setSize
(parentBean.SystemChoicesValue.size());
Any Suggestions on this.
Thanks
Namburi

Namburi--
Remember, the getValues() method does not return the values from a column in
a TiledView. It is strictly for use by fields that can have multiple
values, like multi-select list boxes.
DO NOT remove the indexing feature from the field names, especially in the
case of checkboxes, because checkboxes aren't submitted back to the server
unless they are checked. By overriding the automatic checkbox tracking
feature JATO provides, you won't be able to tell which checkboxes were
actually checked by row--you'll simply get back a list the same size as the
number of checkboxes that were checked, without any placeholders for the
ones that weren't checked.
Instead, on submit, you simply need to move through the tiledView and check
the value of checkbox on each row:
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
You can use the same construct to build up an array or list:
List checkedList=new LinkedList();
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
checkedList.add(new Boolean(true))
else
checkedList.add(new Boolean(false))

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.

How to get the value from the checkbox

Hi All,
Good Evening,
i want to get the value from the check box.
for this i wrote like this
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String val=cbb.getvalue(pageContext).toString();
val getting the value only when checkbox is checked.
suppose check box is not checked that time i got NULL POINTER exceptionn.
so
i tried the following way alsoo
string val=pageContext.getParameter("item240");
here val return 'on' only when checkbox is checked.
otherwise NULL value returnss.
but i want to get the value is 'Y' when i am checked the checkbox
otherwise returns NULL valuee.
already i set the checkbox properties alsoo
Checked :Y
unchecked:N
pls tell me

Hi,
use
try
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String test = cbb.getvalue(pageContext).toString();
catch(Exception e)
String test = "";
this way you can handle null pointer exception.
Thanks,

You mixed Java and Javascript in the expectation that they runs simultaneously.
You are Wrong.
You need to distinguish between the server side languages and client side languages. Java/JSP runs at the server side and produces a HTML page with other client side stuff in it like CSS and Javascript. When the HTML page is finished, it will be sent to the client and then Java/JSP stops. Once the HTML page is arrived at the client, there is no one line Java code in it, only its output/result. Do a View Source in your favourite web browser to see it. Only from that moment on, Javascript runs and/or can be invoked.
Whenever you want to use Java variables in Javascript, you need to print them out as a Javascript variable. Whenever you want to use Javascript variables in Java, you need to invoke a request to the server and pass them as parameters. The request can be either synchronous (a link or a form submit) or asynchronous (ajaxical).
