How to get pulse readout from BPM analysis in biomed startup kit

Hello,
We are trying to obtain an instantaneous pulse reading from a Vernier Go EKG sensor. We tried writing our data to an array in a for loop, then exporting the array to the "array in" node on the BPM analysis tool. We would like a chart displaying the EKG (which we have) and the instantaneous pulse readout (which we get a readout that says not a number). HELP!

Hi TFleck!
I want to premise my response by saying Steve.J had a great suggestion, there might be users in the Biomedical User Group who can help you with this hardware or maybe you could contact Vernier as the Vernier Go EKG sensor and the VI in your attached file uses SubVIs supported by Vernier. In addition, it looks like Vernier provides some tutorials.
Given that suggestion and that I do not have this hardware to test with, there are a couple of things in the VI that look like they could be related to your issue. First, the parameters cluster line from the Read VI output is not connected through to the BPM VI. You might have to wire the parameters so the BPM VI gets the correct configuration data. Second, the BPM VI has an input called Analysis method and the default for that terminal is point-by-point analysis. It looks like the VI you wrote is using data array analysis, so I would recommend creating a constant on that terminal and trying Analyze Data Array.
Hopefully that helps, but if not, maybe someone in the Biomedical User Group knows more about the device or you can contact Vernier and they can support you with some examples.

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

How to get a formula from the user from a text box in a webpage

Hi. I would like to know how to get the formula from the user who enters in a textbox. This formula can have any number of variables starting with a and goes on.
The complexity of the formula can go upto sin, cos, ln, exp. Also user enters the minimum and maximum values of these variables. Based on a specific algorithm (which I use) I would calculate a *set of values, say 10, for each of these variables, substitute in the formula and based on the result of this formula, I select ONE suitable value for each of the variables.
I don't know how to get this formula (which most likely to be different each time) and substitute the values *which I found earlier.
Kindly help me out in this issue.
Thanks

The textbox is the easy part. It's no different than getting a String parameter out of an HTTP request.
The hard part is parsing the String into a "formula" for evaluation. You'll have to write a parser or find one.
Google for "Java math expression parser" and see what you get.
Or write your own with JavaCC.

In the process of getting each number from the parm '(25,23,35,1)' , I also need the position of the number
say 25 is at 1 position.
23 is at 2
35 is at 3
1 is at 4.
the reason I need that is when I build seperate select for each value, I need to add the query number at the end of the select query.
Please see the code I wrote for it, But the select query is having error:-
BEGIN
IF(pi_flag_codes IS NOT NULL) THEN
SELECT length(V_CNT) - length(replace(V_CNT,',','')) FROM+ ----> the compiler gives an error for this select query : PLS-00428:

How to get selected value from selectOneRadio ???

Hi...i want to how to get selected value from selectOneRadio and use it in another page and in backing bean.
Note i have about 10 selectOneRadio group in one page i want to know value of each one of them.
Plzzzzzzzz i need help

You have a datatable in which each row is a question, correct?
Also in each row you have 5 possible answers that are in a radio, correct?
So,
You need to put in your datatable model, a question, and a list of answers (5 in yor case) and the selected one.
So you will have a get to the question, an SelectItem[] list to populate the radios and another get/set to the selected question.
ex:
<h:selectOneRadio value="#{notas.selectedString}" id="rb">
<f:selectItem itemValue="#{notas.valuesList}"/>
</h:selectOneRadio>
Search the web for examples like yours.

How to get actual value from LOV list

Like Subject says: How to get actual value from LOV list. Any help will be appreciated.
Thanks.

Thanks Shay, I did it with bind variable because I'm not using JSF. Is there any chance to post solution using standard JSTL or HTML expression. I have something like this: LOV displays some Companies names:
<html:select property="UserJobCompanyId"
                         disabled="${!bindings[\'UserJobCompanyId\'].updateable}"
                         onchange="submitform();">
              <html:optionsCollection label="prompt" value="index" property="UserJobCompanyId.displayData"/>
            </html:select>and I want to get CompanyID of selected Company.
Thanks, again.

How to get column value from DB grid

Hi!
I wander how to get col value from GridControl?
My app consists of one rowsetinfo with two
columns CODE and DESCRIPTION and a jbutton
titled SELECT. When user clicks SELECT button
the app should show the value of the CODE col
of the selected row in GridControl.
I wander how to make this action ?
XxpsTransTimesMasterIter.setAttributeInfo( new AttributeInfo[] {
CODEXxpsTransTimesMasterIter,
DESCRIPTIONXxpsTransTimesMasterIter} );
XxpsTransTimesMasterIter.setName("XxpsTransTimes");
XxpsTransTimesMasterIter.setQueryInfo(new QueryInfo(
"XxpsTransTimesMasterIterViewUsage",
"lov.XxpsTransTimes",
"CODE, DESCRIPTION",
"XXPS_TRANS_TIMES",
null,
null
));

Hi,
You could attach an ActionListener on the JButton, and try the following code :
NavigationManager fm = NavigationManager.getNavigationManager();
DataItem dataItem = fm.getFocusedControl().getDataItem();
ImmediateAccess col_code = null;
String code = null;
if (dataItem != null && dataItem instanceof RowsetAccess) {
RowsetAccess rowset = (RowsetAccess)dataItem;
try {
col_code = (ImmediateAccess) rowset.getColumnItem("CODE");
code = col_code.getValueAsString();
} catch (DuplicateColumnException de) {
return;
} catch (ColumnNotFoundException ce) {
return;
} catch (SQLException se) {
return;
JTextField tf = new JtextField();
tf.setText(code);
I haven't tested this code.
I am curious to know, the Object type of the dataItem.If it doesnot happen to be RowsetAccess ..try.. ScrollableRowsetAccess OR ImmediateAccess.
Your code would change accordingly, depending on the instance.Refer to the product documentation for this.
Do let me know, if this works.
TIA

How to get string value from xml in JSF??

In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

How to get selected value from OADefaultListBean.

Hi All,
How to get selected value from OADefaultListBean ?
Thanks,

Hi,
To identify the user's selection(s) when the page is submitted, you would add the following logic to your processFormRequest() method:
OADefaultListBean list =
(OADefaultListBean)webBean.findChildRecursive("positionsList");
String name = list.getName();
String[] selectedValues = pageContext.getParameterValues(name);
To retrieve all the values in the list box, call list.getOptionsData().

String str = (String)vo.getCurrentRow().getAttrbute("RunId");

How to get real value from selectOneChoice with javascript?

Hi,
How to get real value from selectOneChoice with javascript? The event.getNewValue() only gets me the index of the selected item, not the value/title.
JSF page:

function parseAddress(event)
alert("new value: " + event.getNewValue());
</af:resource>
<af:selectOneChoice label="Location:" value="" id="soc4">

How to get the value from databank

Hi,
How to get the value from databank? and how to set the same value to visual script object?
thanks,
ra

Hi,
You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
Thanks
