How to set the background for all components?

hi
Does anybody know how to set the DEFAULT background color in an application.. I need it because in jdk 1.3 the default bgcolor is grey and in 1.5 it is white.. and I wish white as well.. so to make it also white in jdk 1.3 I need to use the (a bit annoying) anyContainer.setBackground( Color.white ); and these are lots in my app.. So my question is: is there such an overall class with a function (say UIManager.setComponentsBackground( Color color ) ) for such a purpose?
any tip or link would be greatly appreciated

How to set a hover for Accordion content?

Hello,
I'm trying to figure out how to make a vertical side navigation using the accordion feature.
I've got it all working for what I want to do except for a hover on content.
I have it set for hover on the labels so it shows the blue bar and yellow text on hover or open like I want.
What I'd like now is to have a background on each content line when I hover on it (and when selected it stays the background shown on hover).
I've got a background image for the yellow gradient highlight shown below, but can't figure out how to set the Content for hover like I did the Top Level Tab.
I'm attaching a couple of files for demonstration in case the above is not clear.
thanks!
kim

Use the css :hover..

How to set enviroment variables for Inso Filter

Hi everyone,
I want to convert word documents to html using CTX_DOC.Filter.According to the documentation,I know I neednot set the 'Inso Filter'in the preference when creating index,but I must set enviroment variables for Inso Filter.
I found the following instructions for it in the 8.1.5 documentation,but I can't understand it well.Is there anyone can tell me how to set enviroments variables for Inso Filter on Windows2000 Server?(My DB version is 8.1.7EE)
Environment Variable Locations
All environment variables related to Inso filtering must made visible to interMedia Text. Set these variables in the following locations:
listener.ora file. This makes the environment variables visible to the extproc PL/SQL process.
The operating system shell from where ctxsrv server is started. This makes the environment variables visible to the ctxsrv process, which does background DML.
Any suggestions are apreciated
Reemon

NSAPI plugins are normally configured using parameters specified in magnus.conf and/or obj.conf. What plugin requires you set an environment variable?

How to set the fix size jframe window

when I run the jframe ,the jframe window size is very small
1)how to set the fix size jframe window??
2)how to set the jframe cannot change the window size??
thx~~

1. You can set the size by calling JFrame's method setSize. There are two versions of this method: (1) setSize(int width, int height) and (2) setSize(Dimension d). Note, that when you use this method to set the frame size, you don't have to call JFrame's pack method.
2. JFrame has a method called setResizable(boolean resizable) which you can call with the argument false.
Without any ill intent, these questions are regarding something that is very easily answered by looking at the documentation for the JFrame class. I suggest to anyone working with swing to at least look briefly through the base classes they're extending before giving up. In my experience it is always more gratifying to figure things out on my own than asking someone. But please don't take this the wrong way, I respect people who seek out help in order to further their knowledge, instead of just giving up.

How to set Compatibility Mode for a single site in ie10

This question was originally posted on the Answers forum -
http://answers.microsoft.com/en-us/ie/forum/ie10-windows_7/how-to-set-compatibility-mode-for-a-single-site-in/187152e3-142a-4d96-8d1b-af82ef571eec
I am having problem with getting ie10 to set ie9 compatibility for a single site (sharepoint.contoso.com).
When I add this website in Compatibility View Settings (Alt > Tools > Compatibility View Settings > 'Add this Website') it adds the domain 'contoso.com' and not the individual website (sharepoint.contoso.com).
This cause other sites (www.contoso.com) to be configured to use compatibility mode. Because this is a separate site (different web server) to the site sharepoint.contoso.com (sharepoint 2010 server) we need different compatibility settings.
Using a different example to explain the issue -
Microsoft has three websites that are different websites created by different developers written in different programming languages and they only work with certain browsers.
microsoft.com (Website1 created by Developer1) - compatible with ie8/ie9/ie10
msdn.microsoft.com (Website2 created by Developer2) - compatible with ie8/ie9
technet.microsoft.com (Website3 website created by Developer3) - compatible only with ie10
The only thing the three website share is the URL contains 'microsoft.com'.
Marking 'msdn.microsoft.com' to run in compatibility mode affects the other 2 websites - mainly technet.microsoft.com which will not work now since it only runs in pure ie10 mode.
Should you be able to add an individual site to the compatibility list instead of all sites that have .microsoft.com in the URL? Am I missing a simple setting in the ie10?
As a workaround I am using the F12 Developer Tools to set the Browser Mode which temporary sets the compatibility mode. However this is not a nice solution to the end users at our organisation.

problem is not solved for non corporate environments...
You could start your own thread. Then if you got that answer and it was marked Answered you would have the ability to unmark it. The OP of this one seems satisfied. Also note that this is TechNet. Consumers can get help on Answers
forums.
Robert Aldwinckle
Oh! I wrote it wrong: I should have said: This is not solved for NON-AD environments. No demands what so ever to use Window 7/8 professional in a small corporation or on a big corporation with Island of smaller departments for example offshore.
The problem is that the thread is not "Answered" by the OP, its is marked answered by a moderator (and same moderator that did the answer) so no way of telling if the OP is satisfied.
But you are right in the fact that I am almost kidnapping the thread. But a complete answer would benefit all in this case I would presume.

How to set default values for boolean columns

I'm trying to deploy some content types and columns into a site with a feature. All it's ok, except that I'm trying to set a default value for boolean columns with no success.
I've tried to set default value at column level:
<Field ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DisplayName="Se publican noticias en español"
Type="Boolean" Hidden="FALSE" Group="Columnas ShaCon" >
<Default>TRUE</Default>
</Field>
and at content type level:
<FieldRef ID="{EFE23A1D-494E-45cf-832E-45E41B17F0CF}" Name="ScopeSpanish" DefaultValue="TRUE" Required="TRUE" />
But in any case, when i create a new item with this content type, default value is applied.
Can anyone tell how to set default values for boolean columns?
Thanks in advance,
Regards,
Sergio

In the field definition you can set
<Default>1</Default>
or
<Default>0</Default>

A good place to start is http://www.javaworld.com/javaworld/javatips/jw-javatip34.html
Also, do a search in this forum on HttpURLConnection. That class allows you to use POST method to send form data to a web server.
"Hidden" variables are only hidden in HTML. The HTTP that gets POSTed to the web server doesn't distinguish between hidden and not hidden. That is, the content you would write to the HttpURLConnection.getOutputStream() would be something like:
hidden=1&submit=ok(Of course, the variable names would depend on what the web server was expecting from the form.)
Also, be sure to set the Content-Type request parameter to "application/x-www-form-urlencoded"
