How to get a character from input stream withjout pressing RETURN key?

In C, we could use getch() form <conio.h> to get a character from the input steam without pressing the return/enter key. How could I tranlate this function for use in Java?

public static char readChar()
int charAsInt = -1; //To keep the compiler happy
try
charAsInt = System.in.read();
catch(IOException e)
System.out.println(e.getMessage());
System.out.println("Fatal error. Ending Program.");
System.exit(0);
return (char)charAsInt;
}

How to get specific character from a string

I have a value such as: 0-5 or 123-30. This is a combination
from 2 different IDs.
All I need is to get the number on the right (5 from 0-5 OR
30 from 123), any number on the right of the "-" character not
including
the "-"
I'm not sure what ColdFusion function can I use safely.
I said safely since all I can find is either Left or Right
functions. With these 2 functions, I need to specify the number of
character to extract while in my case the application is growing so
the ID may currently be only 1 digit each (0-5) but later it may
grow longer (123-5677).
If anyone know the function, please help me. Thank you!

Something like this?
Mid(string, Find("-",string)+1 ,
Len(string)-Find("-",string))
Since
Mid(string, start, count)
and
Len(string or binary object)
and
Find(substring, string [, start ])
Or perhaps ....
ListLast(string, "-")
since
ListLast(list [, delimiters ])

How to get the values from popup window to mainwindow

HI all,

   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.
Regards,
Uday

How to get parameter value from report in event of value-request?

Hi everyone,
The customer want to use particular F4 help on report, but some input value before press enter key are not used in event of "at selection-screen on value-request for xxx", How to get parameter value in this event?
many thanks!
Jack

You probably want to look at function module DYNP_VALUES_READ to allow you to read the values of the other screen fields during the F4 event... below is a simple demo of this - when you press F4 the value from the p_field is read and returned in the p_desc field.

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

23 is at 2
35 is at 3
1 is at 4.

Please see the code I wrote for it, But the select query is having error:-

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.

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.

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().

How to get real value from selectOneChoice with javascript?
