Need code for Dynamic check box creation in struts
dynamic checkbox should be created with details of data stored in database(with check mark for already selected check box).
once user make any change to that page and click submit the result ahould be saved in database..
can anybody explain me how to proceed this.
If any sample source code you have plz do sent me..
consider these are the details in database
1. apple checked
2. orange
3. mango
4. grapes checked
consider a jsp page which should display list of fruits in the datsbase,
the jsp page should retrieve these data and diaplay with check box.
These should be generated dynamically.
Assume the jsp page has option for user to enter some other fruit name which should be updated into database of fruits and that should be displayed with the jsp page during next visit.(i.e) number of fruits in the database is not constant.

Dynamic check box creation in selection screen
Hello,
I am trying to put up some check boxes dynamically in a selection screen. The number: of check boxes required and the 'checkbox label text' is to be retrieved from a database table. I have retrieved all these values in AT SELECTION-SCREEN OUTPUT event. But, I dont know how to create check box parameters using these dynamic values. Please help..hi Giffin,
Create a program with name 'Z_13317_DYN_CHKBOX' and paste the following code in it. Also make ensure that an include with name 'Z_13317_DYN_INCL' is not existing earlier because this program will be overwritten each and everytime.
Z_13317_DYN_CHKBOX will take an integer as an input. After giving input, click on the button on selection screen.
Suppose, if you have given 3 as input and if you have clicked the button, then 3 checkboxes will be generated on your selection screen.

to whatever you want that way you can get the parameter accordingly to do your updates.
<%
ResultSet rs = ....... ;
for( int n = 1; n <= rs.size(); n++ )
while (rs.next()) {
String custName = rs.getString("CUSTOMER_NAME");
String custLoc = rs.getString("CUSTOMER_LOCATION");
%>

Need to set temperature and threshold,
thankxThe instruction manual for this instrument is available from Oxford
Instruments at no charge- they sent me a copy by email as a PDF file. I
don't have it to hand at the moment so can't dig out the relevant info but
it would be worth having the full manual, I think. There's a bit more to a
decent driver than simply setting the temperature, and I'm not sure what you
mean by "threshold".

Dynamic check box status android app
Hello All,
I desperately need your help. I have created dynamically created check boxes depending on my selection for my android app using the following code snippet.
for(var i:int=0 ; i<data.PromptText.length; i++)
chk = new CheckBox();
chk.label= data.PromptText.getItemAt(i);
chk.name=data.ResponsePromptID.getItemAt(i);
chk.addEventListener(MouseEvent.CLICK,ClickEvent);
chk.width = 1000;
chk.height = 50;
addElement(chk);
Now after click on each check box, I need to check which check box of the list of check boxes created ?
Please help me, this is driving me nuts.Hi,
I see you have "addElement" rather than "addChild", so this is Flex, right?
So there is an easier way to do that in any case, I think.
For example, you could use CheckBox to create a custom renderer and then use your PromptText IList as dataProvider to a list, something like this:
1. Your item renderer
[code]
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
