How to fill combo box with list of all SQL server

// do the job
or

please help me to solve this... thanksc#

Hi Valerij,
The ComboBox control in an MSI dialog uses the ComboBox table to populate the items in it. To get what you want, you need to update the ComboBox table in the MSI package with your application and run the MSI package. The following KB article describes how to dynamically populate a ListBox control in Windows Installer:
http://support.microsoft.com/kb/291329
This method introduced in the above KB article also applies to populating a ComboBox control in Windows Installer.
I don't think it's possible to run the application as a Custom Action from within the MSI package because the application will modify the content of the MSI package which is currently running. So you need to launch the MSI package from within your application after updating the ComboBox table. In short, when installing, just run your application which updates the ComboBox table and install the MSI package.
Hope this helps.
If you have any question, please feel free to let me know.
Sincerely,
Linda Liu

Question abt. combo box and database

Hi. I have two combo boxes, A and B. Items in A is obtained from table X, Items in B is obtained from table Y. But, the problem is that whatever appears in combo box B should not contain those in combo box A. How do i go about doing this? Note that values in table X come from values in table Y.Here's an example:
(this is I currently have)
Combo X             Combo Y
Apple            Mango
Orange           Kiwi Fruit
Pineapple        Apple
Kiwi Fruit
Mango          (this is I WANT)
Combo X                  Combo Y
Orange                  Mango
Pineapple               Kiwi Fruit
                        ApplePlease help and thanks in advance.

hi....
First of all, I've designed the two combo boxes with Add/Delete buttons in the GUI. I'm using JSP to retrieve values from database table into my combo boxes.
Actually, I have the two combo boxes already. I have already got the items inserted into combo A from table X using JSP. I am thinking of getting all the values in combo box B from the table Y first, then maybe store them in an array or something, b4 comparing those values with that from combo box A, eliminate those existing in combo box A, and the rest will be stored in combo B.
I do not know exactly how to store values i obtained from table to an array and how to compare arrays.
hope u understand what i'm trying to say, please help if possible, thanks.

**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,
I had a similar situation and i tried to solve it by using XmlHttpRequest Object(used in AJAX).
U can checkout the below example just for further reference delete

Anyone can tell me what i'm missing? or is there any better way to check the existence of a record ?
Thanks in advance :-)

Hi grzegorz,
1. If your sap application server is unix/aix
(and not a microsoft OS),
2. then this kind of secondary databse connection,
   to MS SQL (which is microsoft system),
   is at present not possible.
(BCOS the required system files, for such
   cross - platform connection is not delivery by sap)

Populating Database values into a combo box in STRUTS Framework

Hi Guys,
I am currently working on a STRUTS Framework project and I can't get much resources related to the problems that I'm facing.
Currently I need to populate a JSP file's Combo box with database values. What I don't know here is the syntax used to in STRUTS framework to populate the Combo box with database values. Anyone with experience related to this topic, please kindly help me out.

Struts doesn't define anything about the datab layer. You're free to implement how you will.
Struts instead guides you into following an MVC pattern.
You populate a combo box with values from a bean.
So you need to set up a bean for this page to talk to.
That bean can be populated from the database - but at that point you're in java/jdbc code - and away from the struts layer.
My suggestions
1 - Define a bean to represent the information from the database.
2 - write a method that queries the database, and copies the data into a List of those beans. This will be your Data access layer.
3 - in your action, call that method, and then set the list of beans as a request attribute. Or maybe as a property on a form.
4 - use that list of beans to populate your dropdown box.

Changing xy graph scale using combo box selection

Hello,
I have a xy graph with x scale set to 10k and y scale set to 6 by default.
I have a combo box which i use to select what the graph will display. For example in combo box i have 3 choices, A, B, C.
If i select A, xy scale is set to 10k and 6. If i select B, xy scale is set to 2.5k and 8, if i select C, xy scale is set to 4k and 10 respectively. Is there some functions that i can use to do this?
Thanks.
Solved!
Go to Solution.

Like this (attached)?
Of course, if the data actually follows these mins and maxes, you could just turn on auto scaling and it would do it automatically

Dependent combo boxes using webservice

Hi All,
I'm trying to create a depended combo boxes using af:selectOneChoice, using webservice datacontrol. When i try to change the value of the first combo box which has hard coded values (eg. Continent), The depended combo box (eg.Country) is empty. (which is returned via webservice) When i again change the value of the first combo box, I get the corresponding values(Countries) generated. The very first time when a value is selected is not binded to the model. Why is this happening and how to overcome this issue. I tried using the value change listener and assigned the current value to binding but there was no change in the behaviour.

Thanks for your response Frank. The Sample worked fine. But when i try to implement the same i ran into issues.
First, I created a combo box for continents and a managed bean.
<af:selectOneChoice label="Region" id="soc1" autoSubmit="true"
                              valueChangeListener="#{locateBean.setRegion}">
            <af:selectItem label="Asia" value="Asia" id="si3"/>
            <af:selectItem label="Europe" value="Europe" id="si2"/>
            <af:selectItem label="NA" value="NA" id="si1"/>
          </af:selectOneChoice>Then I created a combo box for countries using the webservice data control.
          <af:selectOneChoice value="#{bindings.Country.inputValue}"
                              label="Country"
                              required="#{bindings.Country.hints.mandatory}"
                              shortDesc="#{bindings.Country.hints.tooltip}"
                              id="soc2" partialTriggers="soc1">
            <f:selectItems value="#{bindings.Country.items}" id="si4"/>
          </af:selectOneChoice>In the managed bean as
    public void setRegion(ValueChangeEvent event) {
        this.region = (String)event.getNewValue();
    }1. When i run and select an continent, the values are not getting populated in the country combo box. If i refresh the page or select another value for the continent, then its is getting populated.
2. When i tried to execute the operation manually at pagedef on value change event,
        OperationBinding operBinding = getBindings().getOperationBinding("GetCountryList");
        operBinding.execute();I'm getting an warning as <FacesCtrlListBinding> <getInputValue> ADFv: Could not find selected item matching value Afghanistan of type: java.lang.String in the list-of-values.Why the value binded to the managed bean or model is not getting updated for the first time. Is this the expected behavior.

Display data in list and combo box

hi all....
how to display data from database in list and combo box? i use MYSQL...
help me please..... tq...

1 - Write a query to retrieve the data you want from database
2 - In a servlet, connect to database, Run the query, scroll through the result set and put the data into a list of Java Objects.
3 - Set a request/session attribute of that list of objects
4 - Forward to JSP
5 - In JSP, create a <select> box, and then use a <c:forEach> loop to generate <option> tags from the list.

Multiple lines in a combo box

Hello,
I am attempting to create a pdf file for the purposes of filling in information and then printing it out. I have very limited skill with Acrobat 8, basically what I've learned myself, and I run into an issue with my combo boxes. Some of the sentences I have put into the boxes are too long and I have not been able to figure out how to wrap the text, or make it use multiple lines. I need all of my data to show. Can someone explain, in simple terms if possible, how this can be accomplished, or provide an alternative. I have read several posts but have not been able to work out where to start with them. Any help would be appreciated. Thanks!

I've been reading through more forums and I think what you suggested was to have shorter options in the combo box that, when selected, generate the full length sentence into a text field. Is that the basic concept? Here is one of the sentences that is too large for my combo box:
5b. Use Mendel's Law to evaluate monohybrid Punnett Squares for complete dominance, incomplete dominance, codominance, sex-linked, and multiple alleles. (DOK 2)
So I could set up a combo box with 5b in this case. I could then write script in the combo box properties that would cause the sentence to be generated into a text field located beside the combo box. If this is the case I would have to write out script for each one of the number/letter combinations correct?
Just for some background info, I'm attempting to create a lesson plan template (I'm a teacher) that has all the necessary information listed so that I don't have to type it all out every time I do a lesson plan.

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;

Multiple combo boxes cause application freeze

I have an application that uses 3 combo boxes, they appear if
the remoting service populates them.
The actionscript is very simple, I only add items, removeall,
and sort them by their label.
If I use old MX combo box, my application works perfectly.
If I use the Version 2 components, the application works when
I select one of the combo boxes, but the second I touch the second
combo box, it locks up the application and I get the message that a
script is running, should I abort...
I am using Flash 8 and want to stick with all V2 components,
but...
anybody experience this issue? I have a lot of other V2
components on the application, all work, except this combobox
issue.
thanks
Josh

You can create a JavaScript array of the items and values to be set into the combo boxes and then use Acrobat's JavaScript's ''setItems()' method to load the fields.
Get various fields (combo or list) and set items in the list using various techniques.
var l = this.getField("ListBox");
l.setItems(["One", "Two", "Three"]);
var c = this.getField("StateBox");
c.setItems([["California", "CA"],["Massachusetts", "MA"],
["Arizona", "AZ"]]);
var c = this.getField("NumberBox");
c.setItems(["1", 2, 3, ["PI", Math.PI]]);
