Simple screen question

How do I bind the following actions in screen?
- New screen
- Close screen
- Next screen
- Previous screen
I'm probably being a bit of a newb here, but I couldn't find anything on google/this forum.

If you know the default key binding, look it up in man screen under Default key bindings.
(in this case: screen, kill (or quit, depending what you mean), next, prev)

4 Simple Flash Questions that Are Stumping Me!

What is the Frame Rate for Web Animations
Q1. I am making an animation which will be played on the web. What is the default frame rate (fps) of Flash CS5? And what is the frame rate of for web?
Q2. My animation needs to be 30 seconds long. So at 15 fps that would mean I need to use 600 frames in Flash?
How Do I Mask everything so all I see is the Content on the Stage?
I have a wide image that extends past my movies stage size so when I preview my movie the image is visible. How do I mask out anything that extends past my movies window size? I believe I can create a layer named "mask" and place it above all other layers, but I forget how to make the mask. Any help is appreciated.
How to Fade a Graphic
I have a graphic element (some type) and I want it to fade from 0% to 100%. In older versions of Flash I could just select the symbol and then set it's alpha value to 0%, move a few keyframes and then set the alpha to 100%. Voila! but now it doesn't seem to work that way. How can I do this in CS5?

Ned, it says 24 fps which means there is 24 frames per second so each 24 frames is 1 second.

1 You can create your character as a movieclip and copy/paste that movieclip from one file to another. 2. One way to create a movieclip is to copy all the frame of the animation's timeline (select them all, right click the selection, choose Copy Frames), then create a new movieclip symbol (Insert -> New Symbol...etc) right click on its only keyframe and chhose Paste Frames. THat will put all the layers and frames you copied into the movieclip The only way to come close to being certain about the timing of you animation is to use code to keep track of the time, something like getTimer().. The frame rate that a file plays at is not a reliable means of dictating the time it takes due to a variety of factors which include the amount of content you are trying to process and performance limits of the user's machine.

Simple performance question

Simple performance question. the simplest way possible, assume
I have a int[][][][][] matrix, and a boolean add. The array is several dimensions long.
When add is true, I must add a constant value to each element in the array.
When add is false, I must subtract a constant value to each element in the array.
Assume this is very hot code, i.e. it is called very often. How expensive is the condition checking? I present the two scenarios.
private void process(){
for (int i=0;i<dimension1;i++)
for (int ii=0;ii<dimension1;ii++)
for (int iii=0;iii<dimension1;iii++)
    for (int iiii=0;iiii<dimension1;iiii++)
         if (add)
         matrix[i][ii][iii][...] += constant;
         else
         matrix[i][ii][iii][...] -= constant;
private void process(){
if (add)
for (int i=0;i<dimension1;i++)
for (int ii=0;ii<dimension1;ii++)
for (int iii=0;iii<dimension1;iii++)
    for (int iiii=0;iiii<dimension1;iiii++)
         matrix[i][ii][iii][...] += constant;
else
for (int i=0;i<dimension1;i++)
for (int ii=0;ii<dimension1;ii++)
for (int iii=0;iii<dimension1;iii++)
    for (int iiii=0;iiii<dimension1;iiii++)
       matrix[i][ii][iii][...] -= constant;
}Is the second scenario worth a significant performance boost? Without understanding how the compilers generates executable code, it seems that in the first case, n^d conditions are checked, whereas in the second, only 1. It is however, less elegant, but I am willing to do it for a significant improvement.

erjoalgo wrote:
I guess my real question is, will the compiler optimize the condition check out when it realizes the boolean value will not change through these iterations, and if it does not, is it worth doing that micro optimization?Almost certainly not; the main reason being that
matrix[i][ii][iii][...] +/-= constantis liable to take many times longer than the condition check, and you can't avoid it. That said, Mel's suggestion is probably the best.
but I will follow amickr advice and not worry about it.Good idea. Saves you getting flamed with all the quotes about premature optimization.

A few simple Logic questions...please help.

I have a few probably simple Logic questions, that are nonetheless frustrating me, wondering if someone could help me out.
1. I run Logic 8, all of the sounds that came with logic seem to work except organ sounds. I can't trigger any organ sounds (MIDI) on Logic, they won't play. I have a Yamaha Motif as my midi controller.
Any idea why?
2. I've starting running into a situation where I will record a MIDI track, the notes are recorded but they won't playback. The only track effected is the one that was just recorded. All other midi tracks playback.
I have to cut the track, usually go out of Logic and back in, re record for it to playback properly. Any idea why this may be happening?
3. How important is it to update to Logic 9. Are there any disadvantages down the road if I don't upgrade. If I purchase the $200 upgrade, do I get a package of discs and material, or it just a web download.
Any help is appreciated!

you titled "simple quick question"...
.. complicated to answer..
a) the TermsOfUse of the iTS don't allow any processing of purchased files, these are "copy protected"..
b) iM has a voice-over function..
c) iM is a video-edit app.. easy to use... just learn to handle it...
d) iM allows to "extract" audio (=muting the original audio, adding your own..)
e) to learn iM, spend some time here: http://www.apple.com/ilife/tutorials/imovie/index.html
f) use pencil and paper first! WRITE and scribble, what shall happen when in your movie/parody... make a script, draw a storyboard .. THEN launch iM.. in other words: think first, then edit.. iM is just a tool, it does not "create"... Picasso needed a papertowel and half a stencil to create art....
g) to get comfortable with iM, start with your own, small, short (3min!) project... import some stills, edit them, add a funny voice-over, add sounds, add music... good? make a bigger one...
h) .. in our Lecture II, we teach you how to import shows from TV, youtube, wherever..

Simple query question

hi all,
I have a XMLType table with one column - I have presently one row, in my column xmlsitedata I have stored one large xml file.The schema definition is given below:
<?xml version="1.0" encoding="UTF-8" ?>
- <xs:schema elementFormDefault="qualified" attributeFormDefault="unqualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
- <xs:element name="siteList">
- <xs:complexType>
- <xs:sequence>
<xs:element name="site" type="siteType" minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
</xs:element>
- <xs:complexType name="siteType">
- <xs:sequence>
<xs:element name="nameEn" type="xs:string" />
<xs:element name="nameFr" type="xs:string" />
</xs:sequence>
<xs:attribute name="code" type="xs:string" />
</xs:complexType>
</xs:schema>
I have executed the query below:
select x.XMLSITEDATA.extract('/siteList/site/nameEn/text()').getCLOBVal() "stName" from wsitelist x;
and I get all english names of some 200 locations, however, there is 1 row selected and all names show up on one row. How do I split them into 200 or whatever rows?
Thanks,
Kowalsky

Simple Selection-screen question

Right now my selection screen shows the variable names that I have assigned. The variable name is limited to 8 chars. I would like to be able to set the text. I know this is a very easy question and Im sorry to waste a forum post on it!
Here's what I got:
SELECTION-SCREEN BEGIN OF BLOCK BL1 WITH FRAME TITLE TEXT-100.
SELECT-OPTIONS: network FOR AFPO-AUFNR.
SELECT-OPTIONS: s_dauat FOR AFPO-DAUAT.
SELECT-OPTIONS: fnsh_dat FOR AFKO-GSTRS.
SELECT-OPTIONS: strt_dat FOR AFKO-GLTRS.
SELECT-OPTIONS: status FOR TJ02T-TXT30.
SELECTION-SCREEN END OF BLOCK BL1.

2 ways,
1) Go to TextElements and selection text and give the description there.
2) Using SELECTION-SCREEN COMMENT
For example
SELECTION-SCREEN BEGIN OF BLOCK BL1 WITH FRAME TITLE TEXT-100.
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN COMMENT 3(20) TEXT-001 FOR FIELD network.
selection-screen position 45.
SELECT-OPTIONS: network FOR AFPO-AUFNR.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF BLOCK BL1.
Here you may need to double click on TEXT-001 and give the description.

Simple audio question (I think)

Thanks everyone for answering this question which I think is fairly simple. I have a new TV that I use as the monitor for my computer and connect my Itv to. Currently I have both the cable, my computer and ITV hooked up through HDMI. Whenever I switch between the different HDMI inputs I obviously do not continue getting the sound out from my ITV. The question is I would like to be able to leave my ITV running while it is playing music to my stereo and surf the internet with my computer output on the screen. I know I could obviously play Itunes on my computer however the ITV seems to have much better output quality. Anyone has a solution for this?
I look forward to your answers. Have a great day and thanks again.

Welcome to the  Discussion Forums.
Not without some other device to feed audio through. Your tv will only play from one input at a time, when you switch to the input from your mac/pc, it will always cut off the audio from other inputs.

[iPhone] Simple UIView question

Hi,
I am trying to figure out why iPhone is behaving this way and I can not figure it out.
For testing, I am trying to display 3 views one on top of the other (using UIViewControllers). The problem is that except for the first one that goes directly on top of the window object, the rest of the views display about 20 pixels bellow the top of its superview
My very-very simple application, my delegate code is like this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Override point for customization after application launch
UIViewController *viewController;
UIViewController *viewController2;
UIViewController *viewController3;
// Create the first ViewController and assign green to its view background color
viewController = [[UIViewController alloc] init];
[[viewController view] setBackgroundColor:[UIColor greenColor]];
// Create the second ViewController and assign purple to its view background color
viewController2 = [[UIViewController alloc] init];
[[viewController2 view] setBackgroundColor:[UIColor purpleColor]];
// Create the third ViewController and assign cyan to its view background color
viewController3 = [[UIViewController alloc] init];
[[viewController3 view] setBackgroundColor:[UIColor cyanColor]];
// Add view2 to view and view3 to view2
[[viewController view] addSubview:[viewController2 view]];
[[viewController2 view] addSubview:[viewController3 view]];
// Set background window color to red
[window setBackgroundColor:[UIColor redColor]];
// Add view to window
[window addSubview:[viewController view]];
[window makeKeyAndVisible];
This displays about 20px of green at the top (from view), below that about 20px of purple (from view2) and the rest of the screen is cyan.
The question is why it is behaving like this and not display the views directly one on top of the other so at the end to show the screen in cyan (from view3 that is the last view added).
I do understand that there are different ways to do this but this is not the point here. I am try to understand why using this way, the iPhone behaves like this.
Thanks for your help.

The window frame is normally set to the bounds of the screen, (0, 0, 320, 480), regardless of whether the status bar is visible. I may have over-simplified my last reply, since this thread is really all about the status bar, which is 20 high. When the status bar is visible, a view controller created in code will have a view with a frame of (0, 20, 320, 460). However, when the status bar is hidden, the very same code will create a view with a frame of (0, 0, 320, 480). The taller view would also work with a visible status bar (since the bar is always on top), but the system is just trying not to waste the upper 320 x 20 area of the view.
Anyway, the coordinate system of the window is the same as that of the screen. So when the origin of the root view frame is (0, 20) there's no offset. I.e. the point (0, 20) relative to the window is also (0, 20) relative to the screen.
But when a second view with a (0, 20) frame origin is added to the first, the point (0, 20) is relative to the root view rather than the window. The point (0, 0) in the root view's system is the point (0, 20) in the window's system, so the point (0, 20) in the root view's system is (0, 40) in the window's system.
It might help to remember that every view object has both a frame property and a bounds property. The frame is defined in the coordinate system of the superview. The bounds is in the object's own coordinate system. So we can expect the origin of the bounds to always be (0, 0). I.e. the upper left corner is always in the same place when you're inside the view. But from outside the view, in the superview, you see the object's frame. The origin of the frame could be anywhere relative to the superview.
When a subview is added, its frame is given in the superview's coordinate system. So if the origin of the subview's frame is (0, 0), that means its upper left corner is in the same place as the superview's upper left corner. But the superview's upper left corner could be at the point (100, 200) on the screen.
Not sure if it will confuse you even more than the above, but try adding this line at the top of the code you posted:
[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];

Simple Scheduling Question

I have a report that takes always Sunday date parameter. If I schedule the report to run every Wednesday with the previous Sunday date parameter, will the date parameter automatically update every week? I am hoping it does. If it does not, how does one go about getting the date parameter to update automatically?
Thanks in advance.

HareshM,
To answer your question, I don't think BI Pub can do this.
I have 2 ideas for you:
1) Modify your SQL so that you can either pass in a date or not. This way the users can pass in a date they choose from the calendar popup window. In the scheduled screen, schedule the report without any date value.
Example SQL:
SELECT *
FROM table x
WHERE ((:p_date IS NOT NULL AND
TRUNC(x.date) = TRUNC(:p_date)) OR
(:p_date IS NULL AND
TRUNC(x.date) = TRUNC(SYSDATE, 'DAY')))
2) If you want the flexibility for your users to pick any date from the popup calendar, then have this date passed to your SQL so that your SQL will use the previous Sunday from this passed in date and the ability to have this same exact report run atuomatically every Wednesday, then this is my idea:
Create 2 reports that are exactly the same. Allow the users to "see" 1 of the 2 reports so they can pass in any date they want. Do not allow the users to "see" the other report. Modify the WHERE clause in the SQL in this 2nd report to programmically select Sunday based off of SYSDATE. Schedule this report to run every Wednesday.
Personally, I like idea #1 above. "Simple is best".
Good luck,
James

Unfortunately I have not tried to play WoW on this MBA yet, it is realy a pain for my ears to listen to the fan noise from such a thin machine. And I also use iStat menus and temperatures like 98-100 C excite me even more. But as soon as I decide to game a bit - I'll post here ))
wickedHangover
Thank you very much for a professional advice ! This information is very usefull, because EVERYTIME I rise the question of high temperatures everyone sais "its ok dont worry, its mac, its Apple, so everything should be ok etc". And finaly I do hear about overheat issues. As for me, I ALWAYS use Just-Mobile Cooling Bar if I use the integrated monitor, otherwise I use Twelve South stand - when connected to an external display (both of these cooling pads provide passive cooling).
So if you do not recommend stressing a work machine I will not do it for sure. I'll look for some other gaming solution...maybe iMac... or replace MBA with new thin MBP . . . Or maybe Apple will intergrate GPU in the upcoming thunderbolt display lol ))))
Otherwise it doesnt make much sence.

Simple Report Question

Post Author: scott123
CA Forum: General
I want to take the information in a simple excel table and recreate it 3 times, each time sorting/grouping on a different columnHere is the tableAnd here is the report that I'm trying to generate (first sorted by name, alphabetically, then grouped by rank, then grouped by size) I'm comfortable working with excel tables in Crystal, but I'm running into a problem repeating the information and then sorting each group separately. I also have no problem doing each group in a single report (without repeating any records), but I'd like to include all 3 groups in a single report. My apologies for how remedial this question is- I thought for sure that Crystal could do this easily but I've spent a couple of days on this and am running into a brick wall.

That's right Scott, and maybe make them "on demand"
sub reports so the user only has to see the data they
really want at the moment. Gives the report a nice clean look too.

A simple security question

I'm trying to write a simple self-signed applet that use a jca provider but thi exception "java.security.SecurityPermission putProviderProperty.BC" is thrown. if I use a policy file, it works fine but for a beginner user is not very useful intall a new policy file.
After this I tried to write a new self-signed applet that read a file and open a ServerSocket on port 21, and it work fine without a new policy file!
My question is this: why is needed a policy file to add a provider and not to open a ServerSoket or read/write a file???????
PS
if u have an idea to resolve my problem without a policy file, tell me pls!!! IT'S URGENT!!

An applet works out of a so-called sandbox. The security restrictions can be overcome in one of two ways that you have tried:
1) by the use of a policy file, or
2) by signing the applet
So, to answer your question:
My question is this: why is needed a policy file to add a provider and not to open a ServerSoket or read/write a file???????Since the applet is signed, there is no need for a policy file......if you tried to access the socket without signing the applet, you'll get the security exception!
