Linking combo boxes to a table

I have made a set of combo boxes that allow the user to input a home and away football team and their scores. I have also setup a table with 4 teams in it. How can i link the combo boxes so that EG:
If Arsenal 2 - 1 Chelsea is a result inputted how can i link it to a table so that Arsenal will go top with 3 points, 2 goal for, 1 against etc
Basically i need to update the table from the info supplied by the combo boxes???

we don't tolerate that attitude either....
besides I gave u guidelines, check the other thread, but u can be sure that nobody will help you if u keep this attitude...
READ the links I posted in that other thread, work on the issue then come back with questions and post your code so that we know how to help you based on your code..that's how it works here..

URGENT!!!!!!!! Using a topic title like "URGENT" followed by exclamations is one sure way to not get an answer from people on the forum.
This is urgent... Not for us it isn't. Implying that your question is any more important than any other question on the forum is another way to not get a response.
Anyway your question is like big run on sentence and I have no idea what you are asking or what your problem is or what your code looks like.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.

**urgent*** -two combo boxes -one database table - ***urgent**

1. i have one html page - in that two combo boxes are there
2. first one called--> Bank Name and second one called-->Main Branch
3. i have a database table like BANK_MASTER(MAIN_BRANCH,BANK_NAME)
i am giving here some data for the above table:
(sbi-kurnool, sbi),(sbi-cadapah,sbi),(sbi-chittor,sbi),(ab-rangareddy,ab),(ab-varangal,ab) ..like that every bank has its own main branch in different location.
MY PROBLEM:
In HTML page, in the first combo box ie., Bank Name will display all the bank name using the table BANK_MASTER ie.,sbi,ab,cb,sbh ...... (its ok - i too get )
main Problem: Whenever i select a particular bank name in the first combo box, the second combo box ie.,Main Branch has to display the main branches using the table Bank_Master depending on the Selected bank name from the Bank Name Combo box ( ie., if we select the sbi, it has to display all main branches of sbi's only, but not other bank's main branches)

Hi friend,

response.getWriter().println(buffer);
catch(Exception exp){

%> I think u may go upon replacing country with your Main Branch and vice versa

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...)

[php+mysql] linked combo box in insert form?

Hi all,
I would like to add two list box on the same insert form.
The two list box should be linked each other with a 1:1 relation.
The data in the two compo box could be static data; no need to use
dynamic data here).
Selecting from list box 1 will automatically select the related value
from list box 2.
Vice versa, selecting a value on list box 2 will automatically select
the related value on list box 1.
Is there a way to do this using ADDT?
TIA
tony

Hi Gunter,
No, I've seen your post just now. :(.
I too I've never seen nothing similar, but the customer said that the
last year another company have done this for him. But I haven't seen
those pages and we can't get the source code :(.
Perhaps a dropdown menu showing two fields could help.
Or, even better, an editable drop down menu that allow you to type
something and it will autocomplete automatically using the first field
or the second field.
Is this possible?
TIA Gunter.

I suppose that this can be done with StackPane but I need some other more universal way to do this because I want to expand the table size. I need to place there the combo box always in a fix position.

Hi. You can do it using an AnchorPane:
AnchorPane.setBottomAnchor(comboBox, 40.0);
AnchorPane.setLeftAnchor(comboBox, 12.0);

Editable Combo box in a JTable

Hi,
Is it possible to have an editable combo Box in a JTable with an item Listener attached to the combo Box?
Based on whatever value the user enters in that column that is rendered as a combo Box(editable) i should be able to do some validation. Is this possible?
Thanks in advance for your time and patience.

Load Combo Box from MS Access

Me and a co-worker are trying to learn the Designer for a proof of concept (yes, that means newbies). We are currently struggling with loading a dropdown combo box from a table in an MS Access database. We have the connection set up and the field assigned to the control. It populates with the first record from the table, but clicking on the dropdown button does nothing. Is it only populating with one record? Is there a property on the control that is not allowing the list to expand?
I saw another thread in this forum on this topic and the last entry in the thread included the phrase "I GAVE UP" - not very encouraging. This functionality is a must-have and seems pretty basic.
Any advice?

I have been trying this using a Data Drop-down List and I cannot get it work. I have a data connection set up and instead of selecting Table from the choice I used an SQL query to select only one column in the table. There are three lines in the script some of which are confusing to me.<br /><br />var sDataConnectionName = "DataConnection"; //I got this one. it was easy<br />var sColHiddenValue = "<value>";<br />var sColDisplayText = "<value>";<br /><br />The last two I'm really not sure what to put there. I tried putting the name of the table column in place of each of "<value>". but it doesn't work.<br /><br />What else do I need to do to get it to work?

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.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"
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:v="clr-namespace:CCIS.View.Case"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
d:DesignWidth="300"
d:DesignHeight="200">
<UserControl.Resources>
<DataTemplate DataType="{x:Type vm:vmPetitioner}">
<v:vPetitioner Margin="0,2,0,0" />
</DataTemplate>
</UserControl.Resources>
<Grid>
<HeaderedContentControl>
<HeaderedContentControl.Header>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<TextBlock Margin="2">
<Hyperlink Command="{Binding Path=AddPetitionerCommand}">Add Petitioner</Hyperlink>
| <Hyperlink Command="{Binding Path=DeletePetitionerCommand}">Delete</Hyperlink>
</TextBlock>
</StackPanel>
</HeaderedContentControl.Header>
<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>
</Grid>
</UserControl>
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.

Analyzer 6.5: Linking Table to a combo box

I created a combo box containing all month from January to December.If the user select for example December, he should get on the report the actual month (=December) and the privious month (=November).How can I do this with analyzer?Additional question: How can I solve this problem when the user select January and he should get January and December on the report?Help is very appreciated.

Depending on how your outline is set up, there are a few different ways you can do this.For starters if you only need to see current month and previous month, then you might want to look at using substitution variables.Assuming you are not looking to use substituion variables because you are looking to give your users a solution that allows them to go back more than one month, you might want to try something like the following. (It might seem a bit long, but since you are dealing with the time dimension and would only need to repeat the process once for each month, it shouldn't take too long to put it in place.)Here's what you can do:When selecting members for your combo box, you should select the top member of you Time Dimension, for instance 'Year Tot'.Once 'Year Tot' shows on the right side of the selection list, you can right click on it and a menu will come up asking if you also want to include children, descendents, etc.; choose at the bottom of the list "Select Subset". Once there, you want to choose from the drop down, 'Expression Contained is', and type the member name 'Nov', (click the add button), then choose 'Expression Contained is' and type the member name 'Dec' (click the add button). Now go to the advanced button and change your connector from 'And' to 'Or'. Click okay.(Basically you are creating a subset that will return November Or December)You now have a member added to your drop down box called "Year Tot" (or whatever you time dim member name is) Rename 'Year Tot' to "Dec" and click okay. You now have a member in your drop down list called 'Dec' that really represents a subset which includes both Nov and Dec. When users click on Dec in the combo box they will see Nov and Dec in the grid.You would then repeat these steps for each month.As far as January showing The current year January and the previous year December, that can be a little tricky. I'm assuming your time dimsnsion is NOT set up as a fiscal year cross over model and instead you have one dimension with your months and then a scenario type dimension with your years. One solution is to add a 13th month to your month's dimension that does not consolidate. The 13th month can be named 'Prior Yr Dec' You would then write a calc script in Essbase to copy your Dec numbers to Prior Yr Dec. (ie "Prior Yr Dec"->2004 = Dec->2003)Once you have this done, you could easily implement the steps above and achieve the results you are looking for.Best Regards,

How can I code a lookup table from a combo box

Hi, I am trying to use combo boxes on a front page which selects a desired gas. I then want this to look up a simple 2D table which returns the associated K factor value to be used. Essentially I need to gain the conversion factor for a selected gas to be used in the block diagram to adjust the outputs and inputs accordingly. I tried to load an excel file into an array and then extract the desired numeric value but failed. Any help would be great. I don’t want to be manually inputting the values in the block diagram because there are lots of them so it must be read in from a file of some sort.
Regards

Hello Sniepsy,
You posted this question in the FieldPoint forum, but the
question appears to have nothing to do with that hardware product. I can’t deduce from your post what
programming platform you are using, but I assume that it’s LabVIEW. If so, you might consider reposting your
question to the LabVIEW forum.
I’ll broadly address your question though. If the number of possible input factors is
small (say in the order of less than 50), the easiest thing to do is just
generate 2 1D arrays with one for keys, and one for values. Make sure the indices match up and just look
up the index of a key in array 1, and index array 2 with that to get your
number. A purist might complain that the
lookup time would be linear, and we can achieve log-time with sorted lists and
advanced structures – but since these aren’t in LabVIEW the overhead of
implementing them might outweigh the benefit.
Hope this helps!
Please let us know if you have further questions.

Access 2010 - How to display data from a table into a text box upon combo box selection?

Hi
I have a a table with 5 columns: month, year, USD, SGD, BAHT.
I created a form with a combo box for selection of the month and year, and I would like to set adjacent text boxes to show USD, SGD, BAHT information. How can i go about doing that?
From the Q&A here, most of them uses the function similar to this "=[Combo0].[Column](1)" to show the data in the text box, but this would require the combo box to list a whole bunch of details if i were to add in more currency values to the
table. Is it possible to not show this information in the combo box, but still populate data in the textboxes base on a selection on only the "month" and "year" in the combo box.

Hi,
According to your description, my understanding is that you want to show only the month/year in the combo box, we can choose the date, and it will display the value of USD/SGD/BAHT based on the month/year.
If it is, I recommend you try the steps:
Create a form based on your data source table>Add the combo box>combo box wizard>Find a record on my form based on the value I selected my combo box>Add mouth and year to selected fields
http://office.microsoft.com/en-us/access-help/create-a-list-of-choices-by-using-a-list-box-or-combo-box-HA010113052.aspx
If I misunderstand something, please let me know. We may upload some screenshots or a sample through OneDrive.
