FileFilter - display in different section
Hi,
I am working with a JFileChooser and a FileFilter. The FileFilter allows you to open xml or dtd files. However, I want the files to be displayed in different areas - xml file in one text area and the dtd file in another.
private void openFile() {
JFileChooser fc = new JFileChooser(".");
ExampleFileFilter filter = new ExampleFileFilter("xml");
filter.setDescription("XML Files");
fc.addChoosableFileFilter(filter);
filter = new ExampleFileFilter("dtd");
filter.setDescription("DTD Files");
fc.addChoosableFileFilter(filter);
filter = new ExampleFileFilter("xml");
filter.addExtension("dtd");
filter.setDescription("XML and DTD Files");
fc.addChoosableFileFilter(filter);
int returnVal = fc.showOpenDialog(this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
try {
if(filter.addExtension().equals("xml")){ //???????????
tpr.textArea.read(new FileReader(file), null);
else if (filter.addExtension().equals("dtd")){ //?????????
tpr.browserArea.read(new FileReader(file), null);
else {
System.out.println("This isn't working");
} catch (IOException exp) {}
} Any help would be great!
anyone got any ideas?

Help finishing up my first flash site - using navigation to display different sections of the site?
Thanks for looking! i am making my first flash site, and im
not sure what to do next in regards to navigating through the site.
I have different sections, home, info, hardware, equipment, etc,
but im not sure how to make each section appear when you click the
corresponding navigation link. i have an idea but im not sure how
to execute it.
Should i make a movie clip for each section (home, info,
hardware, contact), then place each movie clip in its own frame on
the main time line, and on each navigation link button (each one is
a movie clip) use action script and put a gotoAndPlay() code with
the frame number of the corresponding section? so when you click
it, it goes to that frame which has the movie clip that has the
content for that part of site, say contact, or info?? if so how can
i do this?
that sounds really confusing and im sorry but please help out
a beginner! Thank you and happy halloween!

here is a link so you can see the.swf

"Targeting specific timelines in a flash movie can be daunting
in the beginning. But if you start from the main timeline (_root)
and build brom there, it becomes easier to understand.
For eg:
If you have 2 movieclips on your main timeline (_root).
Navigation and Pages.
Inside Navigation you have the buttons, and each button is a
separate movieclip.
Inside Pages you have each page, each a separate movieclip.
to target a specific page number, from a button, there are 2
ways you can go about it. The method that Ned suggested is called
RELATIVE.
-meaning that you target FROM WHERE YOU ARE.
the second method is ABSOLUTE.
-meaning you target FROM MAIN TIMELINE.
Relative is good, but can be confusing when using dot syntax.
Absolute is straight forward and easy to understand, and can
be used from anywhere in the whole movie. The downside, is that it
generally requires a bit more typing.
In the example I stated above, it does not require more
typing. simply say:
_root.page.gotoAndStop(number);
This line can be used from anywhere in your movie, at any
timeline depth, and will work with no worries.
You can also have ALL navigation code on the main timeline on
the first frame. Simply designate the path to the specific button
like so:
navigation.home_btn.onPress = function(){
doSomething;
this tells Flash that the button named "home_btn" located
inside the movieclip called "navigation" will have to doSomething
when Pressed.
I hope this helps you understand targeting a bit more.
Good Luck. -
Messagebox that displays a different randum number every 2 secs
well im having trouble with putting a messagebox that displays a different randum number every 2 secs and closes with a close button. it goes in the print menu option of this simple text editor,you shoud also be able to work in the background while this message box is been displayed.

Conditionally Display Paper Layout Section
I have a report, that uses the Main Section, and the Trailer Section. The Main Section displays summary data, and the trailer section displays detail data.
I need to use both sections because the paper size for each section is different - the summary data only needs to print out landscape letter, but the detail data needs to print out landscape legal.
I also have a format trigger so that the user can choose to display or not display either section of the report. The problem I have, however, is that when a user chooses to not display a section, that page still prints out, it just prints out as a blank sheet.
Is there a way to conditionally display an entire section of the paper layout? (Header, Main or Trailer)You are correct using the trigger to suppress the section content. To get rid of blank pages, add BLANKPAGES=NO to the report call string.

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time? Or even add a "video slide" into the screensaver?
My business has 3 TVs displayed in our lobby, each with its own apple TV and they are all linked to the same photo stream. Currently the Atv screensaver displays the photostream pictures of our products for the default 3 seconds. We just added pics/slides that now display messages and useful info for our customers but I want that info to be displayed for a longer period of time than the pictures to give people a chance to read it.
I tried using flickr and powerpoint as a work around but no luck. I created a slide in powerpoint with play length of 15 secs and saved it as a wmv file. I added that file to a "screensaver" set in flickr and pointed the Atv screensaver to that flickr set. It still displays everything, pics and the wmv file at the default 3 sec.
I know I can increase the duration of all pics in the screensaver to display for longer but the goal is to have the pics display at 3 secs and the info slides to display at 15 secs.Welcome to the Apple Community.
No that's not possible.
If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here -
Setting different pages widths in different sections - Pages 5.2
In Pages 5.2, how does one set different page widths (margins) in different sections?
You can't. Margins apply to the entire document.
What you can do is set the margins to their max width and then use left and right indents for the sections you want narrower.

Two External Displays and Internal Display Over Different Connections
Hi there.
I'm going to be purchasing a rMBP in the very, very near future. However, I am unclear about how external displays work with this. My current display setup at work is two basic 1080p monitors that can be run over DVI, VGA or HDMI. I'd like to keep using these when I start using the rMBP but also gain the advantage of a third screen by using the internal display at the same time (so much space for activities!).
One of the thunderbolt ports will need to be used for an Ethernet connection (there is no wireless here), so this leaves the setup needing to be one monitor run via Thunderbolt -> DVI and the other monitor run via HDMI.
The internet in general isn't being entirely helpful with this. I'm looking for a clear answer of whether the rMBP will run the internal display and the two external displays using this setup under OS X. Some seem to believe that it won't work using different connection types, for example.
Thanks for any help.Hello dljfield,
Thanks for using Apple Support Communities.
If you'd like to use multiple external displays with a MacBook Pro with Retina display, then please take a look at the information outlined below. A 15" MacBook Pro mid-2014 can support up to two external displays using different outputs.

can anyone help me with my apps on my itunes. They have separated for some reason. I have one section of 44 apps and the other has 121 apps. Only the top section will sinc with my ipod because at the side where it says apps, it is only showing the 44 apps and not the section at the bottom
Can you take a screen shot of the iTunes screen and post it? I do not really understand what you mean by different sections.
What model iPod and iOS do you have? Maybe the section that does not sync are not compatible with the iPod.
Were all the apps purchased with one account?
Do you have any Restrictions one that would prevent syncing? Settings>General>Restrictions. -
How to filter the data in different sections (e.g. Report Footers)?
Hi,
I am using Crystal Reports 11 to generate cross-tables.
I plan to generate 3 cross-tabs, and each cross-table will be put in a section. For example, cross-tab1 in Report Footer a; cross-tab2 in Report Footer b; cross-tab3 in Report Footer c.
I know use "Select Expert" to filter data. But, it seems that "Select Expert" filters data for the whole report.
I want to filter the data for each cross-table separately. For example, filter cross-tab1 based on condition1; filter cross-tab2 based on condition2; filter cross-tab3 based on condition3.
How to filter the data in different sections (e.g. Report Footers)?
Thank you in advance.Hi,
Now that you've inserted the subreport just right-click the sub-report and click Edit. The Design page for sub-report should open up.
You can now insert the cross-tab on the Report Header and insert a record selection formula of your choice.
Also, suppress all the other sections of the subreport so the Main report only shows the crosstab without any spaces.
Do the same for all the subreports.

When I click "about this mac" to check on my storage, I get a number of different sections music, movies, etc. but also I get a section called backups, where can I find the files in this section?
Welcome to Apple Support Communities
All the storage in "Backups" is taken up by local snapshots, which are made automatically in all MacBooks, MacBooks Pro and MacBooks Air with OS X Lion or newer and Time Machine turned on.
See > http://pondini.org/TM/30.html I recommend you to leave them there, because they will be removed automatically. However, if you want, you can disable or remove them manually if you want, even if there's no reason to do this. Have a look at the link above for more information -

A senior citizen needs some help.
ThanksSaving each image as different size - is it an option for you? I would save images with their name as: 20x30.png, 16x20.png etc etc.
Or explain whether you want these in a webpage in which case only one image is necessary and different sizes are displayed with good CSS code. this is question for Dreamweaver forum if this is what you want. -
am creating a document with Pages. all pages using "portrait" orientation, except 2 appendices need to be in "landscape". in Word for Windows it is possible to have different page orientations for different sections of a document. is that possible with Pages. Even when i put the appendices in a different section, changing the page orientation changes it for the entire doc.
Make a separate document the size and orientation you want.
Turn that into a pdf and add it back into the original Pages document or into the pdf from from that document.

As if Macs in an enterprise environment could be more difficult to manage, now since our upgrade to OS X 10.7.(4) I have lost the ability to remotely control numerous Macs in our organization. The issue occurs when attempting to control a Mac running OS X 10.7.(4) that has their Display mirrored and the resolution does not match on both displays. What happens is that I can see the remote screen however it does not fill the entire Observe/Control window. Instead, the remote screen takes up about 50% of the window, the rest is black but sometimes will display a mirror image of the remote screen in the black area. What?! Yeah, I've attached a screenshot because this is ridiculous. The real problem is that I cannot control the computer when it has reached this state, the mouse no longer functions properly, it is not clicking where I place the mouse, etc. I have made sure that I have all updates including ARD Client/Server updates. I even tried VNC but as I have come to find out that is a whole other issue (doesn't work, sends me to the login screen, etc).
So here's what I need:
- A patch that is going to fix this issue
- A script to run that is going to change the remote screen resolution (I still have the ability to run remote scripts, etc. simply not Observe/Control)
Ideas?
<Image Edited by Host>I found a way to work around this issue. Not a fix but a work around.
This is little application some one wrote to toggle mirroring on and off.
Mirror Displays
If you put this application in the client computer's /Aplications folder
you can use ARD or SSH to run the app and switch modes.
The problem only occurs for me when a client is set to mirror dissimilar displays with different aspect ratios.
I am only seeing this in Lion 10.7.4 and 10.7.5
Hope it helps someone....
