Combo Box Calculation

I'm trying to make a custom calculation Javascript for a combo box and can't figure out the calculation.
There are a few variables at play. I would like to incorporate a sliding scale for a student's high school gpa that looks like this:
Students GPA:          SAT Score                   ACT Score
2.00                          1010                            86
2.025                        1000                            85
Students GPA=Combo Box1
Combo Box2=(If GPA=2.022, event.value=1010/86)
Combo Box2=(If GPA=2.028, event value=1000/85)
and so on (the scale continues on up to GPA=3.525
How would I calculate that?
Thanks for your help

Combo Box Calculations

Is there any way to use the drop down box or "combo box" with numbers in a calculation for another field.
ex. "Combo box1"= 500 , 1000, 2000 and "Text1" calculation should be "Combo box1 - 25"
It doesn't seem to recognize the number in "Combo Box1" when I try to do this. Any help would be greatly appreciated!
Thanks

What calculation option are you using?
What code are you using?
What do you mean by "does not recognize"?
If you are using "Simplified field notation" you should not have spaces in your field names, unless you use the special escape character to make the space within the field name to be treated as part of the field name.
Have you accounted for the case of no selection made?
Have you looked at what the type of the value is from the combo box?
Do you understand the 2 different ways that the "+" operator works with JavaScript?
Can you provide any JavaScript console messages?
Can you link to a sample form?

Combo drop box calculation?

I'm dont work with acrobat much so please excuse my lack of knoweldge. I have been reading all week and have learned a lot about performing calculations. I have no issues with creating simple add and subtract etc. I have been using mostly text feilds but thought this might be easier using a dropdown combo box. What I'm trying to do is have a a calculation for whichever choice is picked in the drop down. But I can't get it right. I own a window cleaning company and charge more money for multiple level homes. So I have set my drop box to list the choices of 2,3,4,5. I charge $50 per addtional level. So if I picked 2 the amount should equal $50.00. The price rises by $50 per level so if I pick 3 the price should be $100, 4 =$150 etc. But I can't figure out how to make the choices a set price. Right now all I can do is multiply or subtract, devide etc. Which is not working because if I choose 2, then the price =$100. If I choose 3 it =$150, 4=$200 etc. I have tried adding a subtraction calculation at the end of the script of -50 but that does not work as it automaticlly places -$50 in the results field which I don't want because I don't want the customer to think they are receiving a discount with that part of the service. I don't care if I have to manually place the numbers in the field. So if I should be doing this as a text field that would be ok also. I just can't figure out how to get this one working.

Last night I realised there's a small bug in the script I gave you. If you change the value of the combo from something else to zero, the price field will remain the same instead of changing back to zero (which is what I assume should happen). This will fix that:
if (event.value!="0") {
this.getField("price").value = (event.value-1)*50;
} else this.getField("price").value = 0;

Combo box menu calculation of popup size ignores horizontal scrollbar

I have a JComboBox that I've setMaximumRowCount(20). However, sometimes the combo box has as few as 2 or 3 items in it. In those cases as you probably know, Swing automatically calculates how tall the popup should be, in this case 2 rows tall.
However, this calculation ignores the horizontal scrollbar, which basically occupies a "row" itself. This means that if I have combo box with 2 items, the displayed popup will contain the first item, a horizontal scrollbar, and a vertical scrollbar (for scrolling down to the item that the horizontal scrollbar hides) . Is this a bug in Java? If so, are there any workarounds to this?
I've looked in the bug report section using the terms "combobox horizontal scrollbar popup" and couldn't find anything
thanks

the very simple strategy to do is to call removeAllItems() method for the 2nd combox box and then insert the contents. this is because the validate() method is not repeatedly called and so the contents are not updated immediately.

Combo Box Choice Calculation

I have 3 fields.
Field 1 is a combo box that provides the choice BZ7 or BZS.
Field 2 is a text box (Monthly Gross) that calculates another boxes "Base Salary" * 26 pay periods for BZ7. I want it to be set up so that If i choose BZS that calculation will change to 24 pay periods and for BZ7 the 26.

You can set these numbers as the Export Values for each of the options in the combo-box, and then simply use the built in Product calculation option to multiply the value of the combo-box with the "Base Salary" text field.

Adding an event listener to combo box

I am working on a mortgage calculator and I cannot figure out how to add an event listener to a combo box.
I want to get the mortgage term and interest rate to calucate the mortgage using the combo cox. Here is my program.
Modify the mortgage program to allow the user to input the amount of a mortgage
and then select from a menu of mortgage loans: 7 year at 5.35%, 15 year at 5.50%, and
30 year at 5.75%. Use an array for the different loans. Display the mortgage payment
amount. Then, list the loan balance and interest paid for each payment over the term
of the loan. Allow the user to loop back and enter a new amount and make a new
selection, with resulting new values. Allow user to exit if running as an application
(can't do that for an applet though).

The OP already did this to both JComboBoxes.
mochatay, here is a new actionPerformed method for you to use.
I've improved a few things here and there...
1) You can't just cast the ActionEvent's source into a JComboBox!
What if it was a JButton that fired the event? Then you would get ClassCastExceptions (I'm sure you did)
So check for all options, what the source of the ActionEvent actually was...
2) You can't assume the user will always type in valid data.
So enclose the Integer and Double parse methods in try-catch brakcets.
Then you can do something when you know that the user has entered invalid input
(like tell him/her what a clumsy idiot they are !)
3) As soon as user presses an item in any JComboBox, just re-calculate.
I did this here by programmatically clicking the 'Calculate' button.
Alternatively, you could have a 'calculate' method, which does everything inside the
if(command==calculateButton) if-block.
This will be called when:
a)calculateButton is pressed
b)when either of the JComboBoxes are pressed.
public void actionPerformed (ActionEvent event)
        Object command = event.getSource ();
        if (command == calculateButton) //calculates mortgage payment
            int year = 0;
            double rate = 0;
            double mortgage = 0;
            double interest = 0;
            /* If user has input invalid data, tell him so
            and return (Exit from this method back to where we were before */
            try
                year = Integer.parseInt (mortgageTerm.getSelectedItem ().toString ());
                rate = new Double (interestRate.getSelectedItem ().toString ()).doubleValue ();
                mortgage = new Double (mortgageAmount.getText ()).doubleValue ();
                interest = rate / 100.0 / 12.0;
            catch (NumberFormatException nfe)
                /* Display a message Dialogue box with a message */
                JOptionPane.showMessageDialog (this, "Error! Invalid input!");
                return;
            double monthly = mortgage * (interest / (1 - Math.pow (interest + 1, -12.0 * year)));
            NumberFormat myCurrencyFormatter;
            myCurrencyFormatter = NumberFormat.getCurrencyInstance (Locale.US);
            monthlyPayment.setText (myCurrencyFormatter.format (monthly));
        else if (command == clearButton) //clears all text fields
            /* Better than setting it to null (I think) */
            mortgageAmount.setText ("");
            //mortgageTerm.setText(null);
            //interestRate.setText(null);
            monthlyPayment.setText ("");
        else if (command == exitButton) //sets exit button
            System.exit (0);
        else if (command == mortgageTerm)
            /* Programmatically 'clicks' the button,
            As is user had clicked it */
            calculateButton.doClick ();
        else if (command == interestRate)
            calculateButton.doClick ();
        //JComboBox mortgageTerm = (JComboBox) event.getSource ();
        //String termYear = (String) mortgageTerm.getSelectedItem ();
    }Hope this solves your problems.
I also hope you'll be able to learn from what I've indicated, so you can use similar things yourself
in future!

InfoView - How to Restrict values of Month Dimension Combo Box

Product: Business Objects Enterprise XI R2
Version: XI R2
Patches Applied:
Operating System(s): Linux RHEL 4 x86
Database(s): Oracle 10gR2
Error Messages:Steps to Reproduce:
Hello, we are using Business Objects Enterprise XI R2 in the company I work, and we are facing a problem in some web intelligence reports.Our BO version is in Spanish, so maybe I do not translate some BO terms properly into English.
We have the "Time" class in the Universe we use, and in that class, we have the "month" dimension.
When we create some reports in InfoView, we can use the "month" dimension to display the results of that month (dragging and dropping that dimension in the "Analysis Context" Area).
The user can choose values in the "month" dimention through a combobox in the "analysis context" area. The problem is that Infoview allows the user to select the value "all the values" of that dimension, I mean, all the months, so that the results of the report are according to the "automatic aggregation" calculated of the values of that dimension (all the months).
But, we do not want to allow the user to select that value (all the values) of that dimension, because it causes that the report displays incorrect results (we have some percentages that have incorrect values in the aggregation, for example). I hope that you understand the problem I have tried to explain.
My question is how can we restrict so that the combo box (of the month dimension at the analysis context area ) does not allow to select "all the values"?
Is it possible? If so, do we have to make a change in the universe or is it a restriction of the web intelligence repport?
Thank you very much!

Alejandro,
In your posting, quote "(we have some percentages that have incorrect values in the aggregation, for example).", I'm wondering if you are calculating the percentages within your universe or not? I.e. do you have a universe object that in essence is doing the math? If so, I might suggest that you not do it this way (even though in total aggregation calculations this will produce a valid result), but in disaggregate calculations (during the users "slicing and dicing") the percentages are not re-calculated by the BusObjects tool because it thinks that the data it received from the SQL output is good to go, and this is where the incorrect values in the aggregation start to show up. We had this problem too, so we ceased from calculating at the universe level and built a local variable to the report, thus BusObjects will recalcuate the percentage properly for each level of aggregation that user selects. The downside to this approach is that every report that has percentage calculations will require the local variable to be built for that report. Even users who build their own reports will have to build their own local variable to compute the percentage for their reports. The upside is that the calculations will be correct every time.

Question about using the Combo Box feature!

I have a form that I am trying to create for our company that will allow our field nurses to select what they need and print it more effieciently. The problem is that some of the selections are too long and I can't get the Combo box feature to allow them to be printed on multiple lines:
I have spoken to my supervisor about redoing the form to look like this:
But in order for us to meet state guidelines it has to be formated like the first because that is the state form given to us. I want to be able to either:
A) have the combo box multi-line auto text sized so it will get all the information into each box
OR
B) create text boxes at the end of the form that auto enteries the selected data from the second picture into boxes that look like the first picture.
Is there any way to do either of these?

A) No.
B) Yes. Create a text box with the following code as the custom calculation
script (assuming the name of the combo is "Combo Box1"):
event.value = this.getField("Combo Box1").value;
That way, when the user makes a selection in the combo-box, the value will
also appear in the text box. Just make sure to make the text box read-only
and set the combo-box to apply the selection immediately.

I need a combo box with 4 values to choose from which will populate a text box on the form with text related to each combo box selection

For example:
Combo box choices:
apple
tomato
squash
Pumpkin
The text box depending on the selection above would state the color:
Green        (if Apple was chosen from the combo box
Red           (if Tomato was chosen from the combo box
Yellow       (if Squash was chosen from the combo box
Orange      (if Pumpkin was chosen from the combo box
I am very new at this and have spent hours looking for an answer. Thank to anyone in advance who can help!

Place each value as the export value of the options in the combo-box and then use this code as the text field's custom calculation script:
event.value = this.getField("ComboBox Name").value;

Auto-filling a Combo Box

Hi everyone,
I am working on a form using Developer 6, and I have created a list item that is being populated dynamically. The list item is a combo box. I originally used a poplist, but it did not behave the way I intended. I would like to allow the user to be able to type in the letter 'P' and display the first item 'Pan'. Then if the user types in a 'u' after the 'P' they would get another item 'Purse' displayed in the combo box. I have tried using the LIKE% function with no success. Has anyone been successful doing this? If so, what does the code look like? I would appreciate any help you can give me.
Thanks in advance.

It seems as though in my calculation code this line:
if (a=="") event.value = ""
conflicts with this line:
else if(a==0) event.value = "Yes".
I changed the values in my code so that if a>10 it would return a "No" and if a<10 it would return a "Yes" and it worked perfectly. However, when I use the above code (a==0, it just leaves the box blank. I would take out the first line of code (a==""), but I would like the box to be blank until data has been entered into the form.

Help with linking combo boxes so that some options are made unavailable

Hello!
I'm having trouble setting up an interactive PDF form with multiple combo boxes.
I have designed an interactive PDF form in InDesign CS6 but am doing the final preparation and formatting in Adobe Acrobat XI Pro.
First of all, I am not sure if I should be using combo boxes or list boxes, but the combo box seemd to look better after I export the PDF and also left the field blank, ready for selection from the drop-down menu.
Basically I have a list of drop-down lists, but not all combinations are compatible. For example, after maing "Selection 1" in "Combo box 1", I need only "Selection 1", "2", and "3" [out of the total 5] to be available in "Combo box 2".
I need to be able to apply this algorhythm to the next few combo boxes as well.
Moreover, I would need some of the checkboxes disabled [the user won't be able to check them at all]when I make a certain selection in some of the combo boxes.
Needless to say, I don't know any Java, coding or making calculations in LiveCycle Designer, so I don't even know where to begin.
I have attached a screen grab of my form and what I want to achieve.
Any help would be very much appreciated.
Thank you!

If it is static data, I would suggest you to cache it rather than having it in each of the user session. You can have configuration/code to refresh when needed. Please look at any available caching frameworks (EhCache, OSCache etc...)

Calculate combo boxes

Hi I am new to flash and i'm trying to create a roi calculator using two combo boxes. Box 1 how many treatments 5,10,20 Box 2 cost per treatment 90, 100, 120 then button to calculate treatment x cost and a dynamic text field to display result. I am using Flash CS4, am I wasting my time with combo boxes I have searched flsh docs all day. Any help would be greatly appreciated. thanks

Here's a link to an AS3 example. The data is added to the combo boxes via the properties panel "Parameters" section. It includes some simplified checking to see if both selection have been made.

Combo box with multiple variables pre populating multiple fields and max value validation script help

I am creating a pdf form that will be used as a calculator, and my javascript knowledge is pretty rudimentary. I can do the simple things, some of what I need to do is over my head.
1. I believe I need to use a combo box to pre populate certain fields. I have 13 variables in the dropdown to choose from, and whatever the client chooses will pre populate three other fields (and each of the 13 variables will populate those three fields differently). I'm not exactly sure how to go about doing this. Is it custom keystroke script or does it require a document script? Also, I'm guessing that whatever script will be a series of if/then statements, correct?
2. Once all the fields have been populated (be it pre population or filled in by the customer), I need to calculate the answer which is not my main problem—I already have the proper calculations in place and they work. The problem is that the answer has a maximum value even if the actual value goes over that max number. So, the actual answer is 14 but the max value can only be 12. How do I get the calculation to replace that actual number (14) with the max number (12)? Is that in the validation tab or should that go elsewhere?
I feel like I know just enough to be dangerous but not terribly effective. Any help is appreciated.
Thanks!

1. There is a tutorial on this here:
http://acrobatusers.com/tutorials/change_another_field
2. To set the maximum value to 12, try this as the custom calculation script for the field:
//Custom calculation script
//Get value of text field
var a = this.getField("Text1").value;
//If it is > 12, then make it 12
if (a > 12){
a=12
event.value = a
You need to replace "Text1" with the name of the field in your form.

How to populate data in the data table on combo box change event

hi
i am deepak .
i am very new to JSF.
my problem is i want to populate data in the datatable on the combo box change event.
for example ---
combo box has name of the city. when i will select a city
the details of the city should populate in the datatable. and if i will select another city then the datatable should change accordingly..
its urgent
reply as soon as possible
thanks in advance

i am using Rational Application Developer to develop my application.
i am using a combo box and i am assigning cityName from the SDO.
and i am declaring a variable in the pageCode eg.
private String cityName;
public void setCityName(String cityName){
this.cityName = cityName;
public String getCityName(){
return cityName;
<h:selectOneMenu id="menu1" styleClass="selectOneMenu" value="#{pc_Test1.loginID}" valueChangeListener="#{pc_Test1.handleMenu1ValueChange}">
                    <f:selectItems
                         value="#{selectitems.pc_Test1.usercombo.LOGINID.LOGINID.toArray}" />
               </h:selectOneMenu>
               <hx:behavior event="onchange" target="menu1" behaviorAction="get"
                    targetAction="box1"></hx:behavior>
and also i am declaring a requestParam type variable named city;
and at the onChangeEvent i am writing the code
public void handleMenu1ValueChange(ValueChangeEvent valueChangedEvent) {
FacesContext context = FacesContext.getCurrentInstance();
Map requestScope = ext.getApplication().createValueBinding("#{requestScope}").getValue(context);
requestScope.put("login",(String)valueChangedEvent.getNewValue());
and also i am creating another SDO which is used to populate data in datatable and in this SDO in the where clause i am using that requestParam .
it is assigning value in the pageCode variable and in the requestParam but it is not populating the dataTable. i don't no why??
it is possible that i may not clear at this point.
please send me the way how my problem can be solved.
thanks in advance

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.

This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email
''' </summary>
Public Class vmPetitioner
Inherits vmParty
''' <summary>
''' The Email object backing this ViewModel
''' </summary>
Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case
''' <summary>
''' Common functionality for ViewModels of an individual ContactDetail
''' </summary>
Public MustInherit Class vmParty
Inherits ViewModelBase
''' <summary>
''' Gets the underlying ContactDetail this ViewModel is based on
''' </summary>
Public MustOverride ReadOnly Property Model() As tblParty
'''' <summary>
'''' Gets the underlying ContactDetail this ViewModel is based on
'''' </summary>
'Public MustOverride ReadOnly Property Model() As tblAdvocate
''' <summary>
''' Gets or sets the name of this department
''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.
Warm Regards,
Arun
