Eliminating the null values from popup list item

Dear All,
i create a popup list,at runtime it shows a null blank value among the values i specified while the combo box is not,
i want to eleminate the blank null value from the popup list.
Need Help.
Thanks & Regards.

Okay,
i create a popup list, populate it in runtime with create_group_from_query builtin.
now when i run the form and click the list item, it display a null value among the other values which are
return from the create_group_from_query .
the procedure is below
procedure Department_proc is
rg recordgroup;
n number;
begin
remove_record_group('RG');------ this is another procedure which checks for Record group existance and remove it.
rg=:=create_group_from_query('RG4','SELECT NAME,TO_CHAR(DEPT_ID) FROM TAB_DEPT_SECTION
UNION
SELECT '||'''All Departments'''||'as name,'||'''0'''||' as name from dual');
n:=populate_group(rg4);
populate_list('control_block.department',rg4);
end;
it display a null value among the other values for the first time is run the form,but when i click it and select a value from it
and the onward click dont show the null value.i want to eleminate the null value even for the first time when the user run the

How eliminating duplicated values from selecItem's List...

Hi guys,
i've a problem.
I've a list of selectItem elements.
private List<SelectItem> names;
filled with some values.
In this values there are some duplicated values, so i need to eliminate them.
How can i do it?
Please help me,thanks

thanks very much...
but i have a problem.
I need to use ArrayList.
What i want now is creating a Set and copying in it the arraylist....it should work???
I've tried in this manner
Once i've created the arrayList names
i've defined
private Set<SelectItem> names2;and i've done
names2=new HashSet();
names2.addAll(names);calling in my page names2.
The problem is that it shows me the same list, with changed order, but without eliminating duplicated values.
Can you help me?

Duplicated values when added to list of list

Hey all,
I'm making a list of lists, when I print the values just after adding in the list of list everything seems fine, but when I print that list where I call it it has duplicate value instead of the 2 different that I see when I first print it, I really don't know what's wrong.
I tried 2 different declarations for the list of list but is the same result, I also tried using index to add the list but no change either.
What is wrong? or how should I do it instead.
Thanks in advance
The code is this
public class ReadFile extends Metrics{
    public List loadFile(String filename) throws IOException{//void

                for (int i = 1 ; i < tempNorm.length ; i=i+2){
                    CharPoints.add(new TracePoint(Float.parseFloat(tempNorm),Float.parseFloat(tempNorm[i+1])));

System.out.println(" Charpoints is "+ CharPoints);
System.out.println(" LISTofCHARS is "+ ListaChars);
INDEX++;
//Close the input stream
in.close();

Logger.getLogger(ReadFile.class.getName()).log(Level.SEVERE, null, ex);
}finally {

while((strLine = br.readLine())!= null) {
                int INDEX=0;
                INDEX++;
}On each iteration of the while loop, index equals 0. Try moving the variable index outside of the while loop.
List<TracePoint> CharPoints=new ArrayList<TracePoint>();By convention variable names begin with a lower case letter, it is an important practise to live by as I was lead to believe CharPoints was a class at first.

How to delete the duplicated records, not just surpress the records?

I am new to CR. Right now I am doing a project which needs CR get query from Oracle. I got the query from Oracle. There are records with duplicated fields. For example (the following only show part of fields):
ID    body_code
1            10
2             10
3             15
4              15
5              15
6              16
I need to only select records (not surpress, because I will do some caluculate later) like following:
ID         body_code
1             10
2              15
3               16
I tried to creat selection fomula in fomula workshop, shown as follows:
onlastrecord;
<>next
but CR said next can be evaluated. I think it must have something to do with the print-time. So what show I do to delete the duplicated records.Thank you very much.

Ting,
Try this:
Insert a group on body_code. Then create a running total called Distinct Count. Field to summarize -> ID, Evaluate on change of group Group # 1 Body Code, and Never Reset.
Then insert a chart in the report header:
In the advanced layout, select body_code on change of and select Distinct Count running total in the Show values.
I hope I understood what you're looking to accomplish.

How do I set the default value to 0 in a property with "money" as the type?

I have an entity with several properties with the "Money" data type. I also have a Money property with a "computed" value that shows the sum of the other money type properties. However, a total will not display if any of the other
fields are left with a null value. Is there way to make the default value set to "0"? I am using c#. Thank you.

Mark, there's a very basic .NET method on every nullable object:
GetValueOrDefault
EDIT: Now I see...please avoid duplicating
questions...
To be clear:
Put GetValueOrDefault on every nullable field used inside your 'TotalDue_Compute' sub
You don't need to define 'TotalDue' as Nullable anymore

What is the Parameter values for passing a password to open a pdf

I need help in finding the Parameter values for passing a password to open a pdf(s)? The software is written in Delphi.

The Copy Protection only protects our Disk from being duplicated and also protects our Software from being copied and used locally.
As far as the password encryption, that is why I created the Post. I was hoping that the password can be coded in our Software to open the password protect PDF that we create. This option would of gave us the security for when the customer copies the pdf to there local drive they would be required to input the password which they would not have access to.

Not able to get the full value from request.getParameter()

hi all,
Iam giving a text input value as" Analysis and tracking" in one jsp form.
while fetching and assigning the value to another variable using request.getparameter , iam getting only the text "Analysis" , the space after it were ignored andnt displaying it.
Help me in solving this.
thanx
Balaji

I think you are code is something like this
<input name="xyz" type="text" value=<%=variable%>>
HTML ignores spaces. Therefore you are only getting Analysis, the first word, when your browser encounters the first space it ignores whatever is present after that.
One way of overcoming this is putting double quotes around the text value
<input name="xyz" type="text" value=<% out.println("\"" + variable + "\""); %>
Thanks.

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);

I am facing error while running Quickpay in Fusion payroll that "The input value Periodicity is missing for element type KGOC_Unpaid_Absence_Amount. Enter a valid input value". Any idea?

I am facing error while running Quickpay in Fusion payroll that "The input value Periodicity is missing for element type KGOC_Unpaid_Absence_Amount. Enter a valid input value". Any idea?

This is most probably because the Periodicity input value has been configured as "Required" and no value has been input for it.
Please enter a value and try to re-run Quick Pay.

Not to display the null values from data base

Hiiii.
In a jsp file i have ten check boxes.The jsp file is mapped to a servlet file for parameter requesting and to
store it in DB.
The unchecked box values has null values.All the values are store in a Mysql DB table.
Again i have to display it in a jsp page from table.
The problem am facing was,how can i display only the values in a row.it must not display the null values and the crresponding column name.
Or any other way is their like below
How i can retrieve only the selected check boxes from tht jsp file.and store in backend.
Thanks in Advance
regards,
satheesh kannan

Here is a rough example that may give you some ideas:
On the JSP page:
<%if(myData.getFirstName()!=null){%>
Your First Name'
<input type="text" name="firstName" value="<%=myData.getFirstName()%>">
<%}%>
In the servlet:
String firstName= request.getParameter("firstName");
if(firstName!=null){
//write it to the database
}
