Select many Listbox - limit the number of items can be selected
HelloI use Jdev 11.1.1.4.0.
I have a component to select many Listbox in a jspx page. Requirement is that the user can select up to 5 items of the listbox. I have to somehow keep track of the number of selection and ask the user if there is more than selected 5. My plan is to:
1 bind the component in a backingbean
2. listen ValueChangeListener and obtain the total number of selected items
3. If selected is greater than 5, prompt the user.
Any suggestion, comment or pointer will be greatly appreciated.
Thank you
Bones Jones
See this example for SelectManyListBox when it prompts a message - when the number of records selected is greater than 2.
Sample.JSPX:
xmlns:f = "http://java.sun.com/jsf/core".
xmlns:h = "http://java.sun.com/jsf/html".
xmlns:af = "http://xmlns.oracle.com/adf/faces/rich" >
*
selectAllVisible = "false".
* Binding = "#{SampleBean.selectManyListBox}" *.
* inlineStyle = "width: 400px."
* autoSubmit = "true."
* valueChangeListener = "#{SampleBean.valueChangeListener}" > *.
*
*
*
*
*
**
* SampleBean.Java: *.
import java.util.List;
Import javax.faces.application.FacesMessage;
Import javax.faces.context.FacesContext;
Import javax.faces.event.ValueChangeEvent;
Import oracle.adf.view.rich.component.rich.input.RichSelectManyListbox;
Import oracle.adf.view.rich.context.AdfFacesContext;
public class SampleBean {}
private RichSelectManyListbox selectManyListBox;
public SampleBean() {}
}
{} public void setSelectManyListBox (RichSelectManyListbox selectManyListBox)
this.selectManyListBox = selectManyListBox;
}
public RichSelectManyListbox getSelectManyListBox() {}
return selectManyListBox;
}
* public Sub valueChangeListener (ValueChangeEvent valueChangeEvent) {*}
* if (selectManyListBox! = null) {*}
List = (List) valueChangeEvent.getNewValue () selectedValues; *
* if (selectedValues! = null & selectedValues.size () > 2) {*}
* this.selectManyListBox.setValue (valueChangeEvent.getOldValue ()); *
* AdfFacesContext adfFacesContext = *.
* AdfFacesContext.getCurrentInstance (); *
* adfFacesContext.addPartialTarget (this.selectManyListBox); *
* FacesContext context = FacesContext.getCurrentInstance (); *
* FacesMessage msg = *.
* new FacesMessage (FacesMessage.SEVERITY_ERROR, null, *)
(* ' The number of values selected in the selection list box number cannot be more than 2 "); *
* Context.AddMessage (null, msg); *
*}*
*}*
}
}
Thank you

If (getField("chkBox"_+_i).value == 'Yes') {}
Counter += 1;
}
}
-The function of validation-
function validateCheckBox(name,value) {}
If (value == 'Yes' & meter)<>
Counter += 1;
} else if (value == 'Off') {}
counter = 1;
} else {}
getField ("name") .value = "Off";
App.Alert ("you can select only four checkboxes");
}
}
-End of Document Javascript-

Need to limit the number of columns
When a tab in the last cell of the row, I want the cursor to the next line down. Instead, it creates a new useless column. Can't seem to find a setting that allows me to limit the number of columns in a page - someone ' one knows how to do this?
Thanks for your wisdom shared, Oh wise Ones.
I'm not aware of do what you want. You can post your comments directly to Apple using the menu item "numbers > provide Feedback numbers.
You can still use the key combinations:
< command > + < right arrow > to access at the end of a line
< command > + < left arrow > to move to the beginning of a line
< command > + < down > to pass at the end of a column
< command > + < arrow > to move to the beginning of a column

How can I limit the number of Web sites on the new tab page?
Is there a setting where I can limit the number of thumbnails / Web sites that appear on the new tab page? When I opened a new tab - I don't want to see tons of sites I have visited - but also, I don't want to delete them all. For example - there is a setting where the new tab page displays the last ten sites I've visited - with all my pinned sites?
There are two settings 'hidden' for this 'grid '.
Browser.newtabpage.Columns
and
Browser.newtabpage.RowsType of topic: config in the URL bar and press ENTER.
So put . browser.newtabpage in the top search bar.Each of these preferences in the lower panel right-click and select Edit. Then change the value default of 3 for each of these preferences to what you prefer, for "pinned" both sites all browsing history you want to appear in the 'grid '.

Original title: options in window 7
I have an autistic son who likes to play on the internet (usually from sesame street, Barney and AFV videos on you tube).

Hi Brian,.
Thanks for posting your question in the Microsoft Community. It seems that you need more information to improve the performance of your computer.
With the current configuration of Windows, there is no option to limit the number of windows that can be opened. You can search the 3rd application using your favorite search engine, which helps you to limit the number of windows that can be opened.

Get the number of items in a collection
I have an associative array that is indexed by VARCHAR2. I want to know the number of items in the collection that have value of index like '% IMSI_ '. Is there a direct way to achieve this, or I have to loop through the collection and get the number in a variable. I use 11g.
The Count() method gives the total number of elements in the array (including null values).

I have a problem. I added content present on my page in Jdev ide, not at run time. And I need a query including the limitation of the number of results.
My query is: ${' SELECT * from ora: t:IDC:GlobalProfile WHERE the ora: p:xRegionDefinition =-"CSGMNEWS_REGDEF\" ORDER BY ora: p:dInDate DESC'}
I just want to add a number parameter.
Can you help me please? How can I limit the number of results?
Kind regards

Content Presenter has a setting (maxResults) to set the maximum returned results:
Sample:
xmlns = "http://xmlns.oracle.com/adf/controller/binding" Refresh 'ifNeeded' = >
When you add your CP to a page at design time, you can access the pageDefinition and provide more values for attributes of CP.
I hope this help you.
Kind regards.

Limit the number of console sessions
Hi all
Is it possible to limit the number of the Console of the VM by VM session? At work, my team all have access to the same virtual machine, but sometimes if I work within a certain VM, I don't want others to access the VM console even while I work in it. Is it possible to limit the number of session up to 1?
Thank you.
You can edit vmx virtual machine with RemoteDisplay.maxConnections = 1 for a session or another number you want. Changes can be made by editing the virtual machine and select the Options tab and select general and click on Configuration settings...
