How can i control background colors with items (registry.dat)

Hello Evry one.....
plzzzzzzzzz help.
how can i control background colors with display items

how can i control background colors with others items ????
thanks.

The iPhone has a "remote" app that lets you control Keynote on a Mac, but not on another iOS device (iPhone/iPad/iPod Touch).
There are some apps that let you control limited content on another iOS device - but the content has to be within the app. You might check out SyncPad - perhaps you can import the presentation into it and then control it on the iPad.

I'm googling but can not find anything concrete
Any help?
Thank in advance
EDIT:
It was my mistake, the truth is that this application can change the background color, but does so in a cumbersome way.
Each note can change the background color (individually) and to make it globally, you must remove all existing notes and the new notes then take the chosen color :S ...anyway.... issue solved

It is probably more likely that your imported pictures are just covering the background of the button.
A picture ring is the better way to go anyways.

How can I correct background color and graphics in Firefox?

For some reason some background color images and fonts do not appear in Firefox. Other browsers are mostly fine. I've tried most common fixes to no avail. I'm running Windows 7 Ultimate.
I've attached two screenshots. One is Firefox viewing Google. The other one may be relevant because I can't change the color of fonts in Word and other Office docs.
Anyway, I'm stumped on the Firefox side. The browser has been uninstalled, re installed, and refreshed.

Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.

Make sure that you allow pages to choose their own colors.

How can I set the color for a textfield

Hi all,
I use a textfield and I want to set the color for characters which are typed in the textfield. I didn't find anywhere a solution for this. Do you know how I should implement this?

Not possible. If you want this, you'll need to make a custonItem that implements this.

How do I set background color of cell using JTable?

Hello all!
I have a question on the use of JTables. I am using a JDialog consisting of a JTable and a number of buttons to insert and to select OK or cancel. Everything is working perfectly, but I now must add editing capabilities to prevent invalid data being used in a SQL query to update or insert rows.
So far I can't figure out how to get at a cell to set the background to red if the user inputs a Date incorrectly. Upon setValueAt(), I take this value and check for standard format errors. I hope to someday convert the column altogether to a Data object (or some form since Date is deprecated):-) For the time being, I know when an error occurs, but don't have the foggiest idea how to render the error (set backround to red).
I need to give you more info too, since the way we do things is to make it as complicated as possible for job security and to impress the newbies(or scare them back to COBOL). When I setValueAt(), I have a DefaultDataElement object that houses everything for a given column in DB2. It has column name, length, data type, is it new, original value, current value, etc. If one doesn't exist, then I create one. After all said and done, I parse thru these elements and build my update/insert query and then execute the query.
The event starts as soon as the user presses the OK button. But, if a date cell contains an invalid date, I need to halt processing (which I've done) and somehow let the user know which cell was invalid. We consider our users dumb (they really aren't, but the assumption is made), so I can't just say "error occurred in table. Verify data and try again". That won't work:-) Gotta be able to show them what cell is bad.
Any ideas?
Thanks,
Patrick

I finally figured it out. I was always close, but it wasn't until late yesterday that the light bulb came on. I was setting the background on the component in getTableCellEditorComponent() by grabbing the super.getTableCellEditorComponent(). The problem was all this was located in an editor, not renderer. So what happened was as I edited the cell the check would be performed then, not as focus was lost. When focus was lost, the red background went back to normal.
I ripped the code out and made a custom renderer and got closer. Problem was the whole column had a red background. Even specifying the row and column in getTableCellRendererComponent didn't apply just to that cell. That row and column is only for obtaining the data in the cell, but anything affecting the component will affect the column, since I added the renderer to my TableColumn:-) I need to add error logic to my model and when an error occurs, set a boolean flag in a 2 dimensional array where the row and column is used to get to it from the renderer.
Thanks for the help!!!

Can't set background color of boolean

I'm trying my hand at a custom control. It's a simple boolean 'arrow' indicator. I started by placing a classic "flat square button", then imported the 'false' and 'true' versions of the arrow, which correspond to red and green.
However, I want a 3rd state (off). To accomplish this, I tried to use a property node, but it doesn't seem to work. I created a simple VI to test with, I've pasted the image below...I know the event structure is being executed, because I tested that by changing the boolean text inside the event structure. To prove it can be done, I set every value of the array to blue, just to make sure I wasn't missing something about the true/false/t->f/f->t arrangement of the array.
But all to no avail...I can click on the control and it changes from red to green, like I originally defined in the control. Why can't I programatically change the color? thanks in advance

How can I set button colors from xml file data?

I am reading an xml file to create a group of buttons. I am
also using repeater to create the group of buttons.
I am getting the buttons created, but am unable to set the
fill color properly. I keep getting the error "Implicit coercion of
a value of type String to an unrelated type Array" if I try to plug
in r.currentItem.value, even when I used an Actionscript function
to convert from a String to an array of 2 uints. Is there a simple
type casting solution to this I'm just not getting?
Any help would be greatly appreciated!
The xml file has the following format:
<colors>
<color>
<name>Canteloupe</name>
<value>0xFFCC66</value>
</color>
<color>
<name>Banana</name>
<value>0xFFFF66</value>
</color>
<color>
<name>Lemon</name>
<value>0xFFFF00</value>
</color>
<color>
<name>Honeydew</name>
<value>0xCCFF66</value>
</color>
</colors>
The code I have so far is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="

If I send an array of 2 uints via a function call that
converts from String to Number to uint in an Actionscript function
and try to feed that into fillColors via:
<mx:Script>
<![CDATA[
public function fillcolors (_colorvalue:String):uint {
return uint(Number(_colorvalue));
]]>
</mx:Script>
<mx:Button height="15" width="15"
toolTip="{r.currentItem.name}" x="10" y="10"
fillColors="[fillcolors({r.currentItem.value}),fillcolors({r.currentItem.value})]"
I still get the "Implicit coercion of a value of type String
to an unrelated type Array." on the line that creates the button. I
have tried returning an Array of two uints with the Actionscript
funtion and get the same result.
<mx:Script>
<![CDATA[
public function fillcolors (_colorvalue:String):Array {
return new Array(uint(Number(_colorvalue)),
uint(Number(_colorvalue)));
]]>
</mx:Script>
<mx:Button toolTip="{r.currentItem.name}" height="15"
width="15" x="10" y="10"
fillColors="[fillcolors({r.currentItem.value})]"/>
Am I mistaken in my conversion of r.currentItem.value to
fillColors as arguments? Sorry about the newbie question - the
error I get makes me think it is a type conversion issue, but I
can't seem to get this to work/compile. If fillColors is expecting
an Array, should the Actionscript function returning an Array at
least get this to compile?

Thanks in advance for your support

Hello,
I don't think this is documented in BIP's manuals.
All you will find regarding "changing the colour" is related to conditional formatting
see section 3.8.3.5 About Conditional Formats from Fusion Middleware Report Designer's Guide for Oracle Business Intelligence Publisher
http://docs.oracle.com/cd/E28280_01/bi.1111/e22254/create_lay_tmpl.htm#cond_format
If you open a service request to support we can open an enhancement request with Development.
If this will be approved, you can have this option implemented in future versions.
