What would be the better approach at showing a course is complete?
(OT: I'm being evlauated to do some online software simulations using Captivate so I'm trying to merge my Authorware "thinking" with Captivate)
I have a 14 slide simulation; task to edit preference files. Scoring is not necessary but getting to slide 14 is all that is necessary.
Presently I have a click object on slide 13 whose reporting options is "Include in Quiz" with adding 1 point.
So I have a course with Objective ID=Quiz10111 Interaction ID=Interaction11184 and a score of 1.
But I also note in the reporting preferences I could use "Slide views only." So maybe this is all that is necessary?
I'm not that savy (yet) with LMS's but if I wanted to write this data out as a tab delimited file on the hosting server what should I consider? Authorware had a function "WriteExtFIle." Would a button on the last slide set to execute Javascript be a better approach?
Another idea looking for a point of view. If I get the project I am considering a 2 month contract Adobe Acrobat Connect Pro to get more confortable with this approach. Would this help?
FYI...I just downloaded the Captivate 4 manual. Last modified on May 19th according to the doscument.
Thanks
Regarding your function hanging, that seems to be because your loop never ends. Also the inner query is missing a WHERE clause:
Select Translate(comnt_rec.comment_text,'%#$^',' ') into repvalue from test_comnt; <-- How many rows will this bring back?However I don't think you meant to query the test_comnt table at all - it looks as though you just wanted to assign the result of the TRANSLATE expression (btw please, TRANSLATE() or translate() but not Translate() - the parser doesn't care but it drives me nuts), in which case just
repvalue := translate(comnt_rec.comment_text,'%#$^',' ');or even include the expression in the cursor itself and save yourself the trouble.
Another thing that drives me nuts, although not the rest of the world apparently, is the name "c1" for a cursor. Why don't you name your variables "v1", "v2" etc? If you had two cursors would you seriously name the second one "c2"?
While I'm at it, what kind of a name is "test_comnt"?

Which would be the better approach?
Hello!
I'm a working java professional, but has taken on some courses on the local University.
Of course there is a difference in how things are solved in theory and practise, but it makes
me wonder what the "best" solutions to some problems are...
Consider the following structure:
class Book{
private List chapters;
class Chapter{
private List pages;
private Book book;
public Book getBook(){
return this.book;
class Page{
private List chars;
private Chapter chapter;
public Chapter getChapter(){
return this.chapter;
class Char{
private Page page;
public Page getPage(){
return this.page;
public void method(){
// blabla
}Check out the "method" in class Char. Say I would like to have a reference to the Book that this character is in. I would say that I have two choices:
1. call getPage().getChapter().getBook()
2. put a getBook() in each of the classes
Where I come from it is a bad thing to "expose structure", the first example exposes structure.
But, it is also a bad thing to let classes do things that they aren't responsible for (cohesion).
What solution would you prefer?Hi!
With getPage().getChapter().getBook() surely you are having too high coupling and also exposure.
In just one code line you are coupling to three classes and also violating twice De Meter assumption about not accessing class internal structures as character accesses to chapter through Page and to Book through Chapter.
The problem is in the main design idea i think...you are just designing data structures as if you would be designing db entities, with double dispatches between all classes as you would connect db tables with joins but this ends with no real reusability, think to this.... you can't reuse any of your classes without carrying all of the others.
For example why a character should be linked to a book, a character can be an actor of many books but it's not connected to a specific book. A character class should be reusable in movies, lyrichs, books, dreams. Why you want a Chapter to know what is a book?? In concrete that means that every time you modify the book class you must recompile also the chapter cause it's directly connected to the book class and also you can use your Chapter class only within your Book class, it's not reusable at all.
You want to search characters within books? ok you just need an external components that will enter the library and ask to any book what's it about and which characters play in it if it is a characters book,
so everyone will just expose services for the data it's responsible for. -
Deallocate Memory - What would be the best approach?
Hi folks,
we are still struggeling with our memory issue:
"Finding Memory Leak in LabVIEW"
I found now a function "deallocate memory" that is supposed to collect
garbage after a vi terminated.
Does anybody know good approaches on how and where to effectively use this
function?
Thanks again, Sebastian DauHi Sebastian,
This thread
http://forums.ni.com/ni/board/message?board.id=170&message.id=102068&requireLogin=False
contains the bulk of my comments on the subject.
That is a very expensive option but it is useful. Allocating and deallocating memory are very expensive time-wise.
I hope that gets you started.

Hi, I was just making a program that access a DB through JDBC, and I got myself into this dilemma
What's the better approach to make a connection to a DB?
approach #1(use of singleton pattern)
import java.sql.*;
public class DBConnection {
private ResultSet rs;
private Connection conn;
private PreparedStatement ps;
private static boolean singleton = false;
private DBConnection() throws Exception{
Class.forName("driverPath").newInstance();
conn = DriverManager.getConnection("url", "user", "pass");
singleton = true;
public static DBConnection getInstance() throws Exception{
if(singleton)
return null;
return new DBConnection();
protected void finalize() throws Throwable {
//close the connection and release resources...
singleton = false;
//Methods to make DB querys and stuff.
}approach #2 (make a connection only when doing querys)
public class DBConnection {
private ResultSet rs;
private Connection conn;
private PreparedStatement ps;
public DBConnection() throws Exception {
Class.forName("driverPath").newInstance();
//Just some random method to access the DB
public ArrayList<Row> selectAllFromTable() {
ArrayList<Row> returnValue = new ArrayList<Row>();
try {
conn = DriverManager.getConnection("url", "user", "pass");
//make querys and fill the arraylist with rows from the table
} catch(Exception ex) {
returnValue = null;
ex.printStackTrace();
} finally {
if(ps != null)
ps.close();
if(rs != null)
rs.close();
if(conn != null)
conn.close();
return returnValue;
}I know this classes maybe don't even compile and I don't handle the Exceptions, I'm just trying to make a point about how to manage the connection
So, what it's the better approach in your opinions? #1? #2? neither?Hi,
I'm resurrecting this thread to ask is this approach OK?
I'm trying to make a single MySql JDBC connection accessible throughout the model.
I'm planning to use it in a Swing application. Whilst I realise the Swing apps are inherently multi-threaded, everything I plan to do can (I think) be done within the constraint that all access to model happens on the EDT, and the user will just have to wear any unresponsiveness.
package datatable.utils;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public static final String URL = "jdbc:mysql://localhost/test";
public static final String USERNAME = "keith";//case sensitive
private static final String PASSWORD = "chewie00";//case sensitive
private static final Connection theConnection;
static {
String driverClassName = "com.mysql.jdbc.Driver";
try {
Class.forName(driverClassName);
theConnection = DriverManager.getConnection(URL, USERNAME, PASSWORD);
} catch (Exception e) {
throw new DAOException("Failed to register JDBC driver class \""+driverClassName+"\"", e);

Which would be the better choice?
I am presently using a EOS T3. What would be the better choice for an upgrade? A T4i, T5i or 60D?
Solved!
Go to Solution.Good.
One thing you don't have is a wide aperture lens. With the savings plus just a bit more you should treat yourself to a 50mm f/1.4, or for just $100 get a 50 f/1.8. They do almost magical things wide open and close to a subject. Subject is isolated, background is blurred bokeh, background lights are big round disks. Plus they are great in low light. Too fun.

Can I connect an external hard disk to time capsule? I tried but it doesn't show up. What would be the reason??
The USB drive must be formatted for Mac in Mac OS Extended (Journaled), or if you want to use both Mac and Windows files, the drive can be formatted in FAT32.
A number of drives are formatted for Windows only in a format called NTFS. This willl not work on the Time Capsule.
In addition, the USB port on the Time Capsule is under powered. You almost always have to use a powered USB hub when you connect a drive to the Time Capsule...even if the drive has its own power supply. -
I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.
From what I read, I have 2 choices: 1. to install OSX and then upgrade to Mavericks, but I'm not sure if this would be possible (to upgrade directly from OSX to Mavericks); and 2. to use a software called Super Duper.
I wouldn't like to have to use a third party software to do this, so the question is: is there a better way to install directly the Mavericks not having to use a third party software?Install the new drive in the computer.
Install the old drive in an external USB or Firewire enclosure.
Boot the computer from the Recovery HD on the external drive.
Use Disk Utility to partition and format the new internal drive.
Clone your external drive to the internal drive.
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the Recovery HD on the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the Recovery HD then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your new hard drive (this is the entry with the
mfgr.'s ID and size) from the left side list. Note the SMART status of
the drive in DU's status area. If it does not say "Verified" then the drive
is failing or has failed and will need replacing. Otherwise, click on the
Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from
the drop down menu to one. Set the format type to Mac OS Extended
(Journaled.) Click on the Options button, set the partition scheme to
GUID then click on the OK button. Click on the Partition button and
wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the
drive entry) from the left side list. Click on the Erase tab in the DU main
window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the
Options button, check the button for Zero Data and click on OK to
return to the Erase window.
6. Click on the Erase button. The format process can take up to several
hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Using Disk Utility still opened.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
Destination entry field.
6. Select the source volume from the left side list and drag it to the
Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer. -
What would be the simplest way to view and take control over the internet?
Hi All:
Can some one tell me what would be the best and simplest way to connect from my laptop to another laptop through the internet?
I have DYNdns running on the second laptop and have a host name assigned to that system for it to update the IP since the system uses different internet connections. The services that I would like to be able to have are the viewing and controlling of the system. I've read some where in this NG that if I have a copy of ARD admin. installed on that system also, it would be one way to do it... can some one verify this and please let me know if there are any specific settings I need to have on either one of the systems.
I can connect to the second laptop while in my home network with no problem and perform all tasks. when trying to connect through the internet.. the system shows offline .
Both systems are identical in hardware an software, Intel 2.16, 2G's RAM, OS X ver 10.5.2 all up to date and ARD 3.2
Yes, I'm new to ARD and yes I'm searching the NG and the net. but I figure it doesn't hurt to ask since time is limited.
All help greatly appreciated ..
TIA
Oscar A.To be able to connect to a workstation from outside it's network, the ports that ARD uses must be open on both ends of the connection. ARD uses ports 3283 and 5900 so those must be open.
If your workstations get their addresses from an NAT device rather than being "real", the ports also need to be forwarded in the router to the workstation's internal IP address. ARD uses port 3283 for the reporting and updating function, so if your Macs are getting their IP addresses through NAT, since you can only forward a port to a single workstation, you can only get reports, push package/files to etc. for a single workstation.
ARD uses the VNC protocol for observation and control, though, and there are a range of IP addresses for that protocol, starting with 5900. ARD uses 5900 by default, so that port would be forwarded to the first workstation. You would, I believe, need to install VNC servers on the systems (since the ARD client cannot listen on any port other than 5900 while VNC servers can be set for other ports such as 5901, 5902, etc. You would then forward 5901 to the second workstation (and on to 5902, 5903, etc.). You can then use the following information:
Remote Desktop 2: How to specify a port number for a VNC client
to connect.
The only other options are: 1) to run the ARD administrator on a workstation on the network, and then take control of that system from outside, either via VNC or another copy of ARD, or 2) set up a virtual private network (VPN) so that when you connect from outside, your admin system is officially part of the local network.
Hope this helps. -

I want to delete my icloud-account from my iphone 5 and then register again, because I want to change my email-address/account name. What would be the steps to follow? How do I make sure I do not lose any information stored on/in my iphone 5?
You would have to delete the existing iCloud account and create a wholly new one - you cannot change the @icloud.com email address of the one you already have. To make a new one, you will also need an new AppleID as any AppleID can only have one iCloud account associated with it.
Deleting the account will not delete anything off your device (if prompted for things like contacts, choose to keep them). You will have to sync everything anew with the new account as you cannot move your sync'd content, your old backups or anything else from one iCloud account to another. You will have to set up sync again and let it sync to the new account, and then make new backups to the new account as well. -

Does Adobe Reader for iOS have the ability to open inbedded links created with Acrobat Standard to additional PDF docs? If not, then what would be the best way to use these already created PDF's on an I Pad?
driddy61,
As of June 2014, none of the Adobe Reader mobile products support the hyperlink action for opening a separate PDF document.
Adobe Reader for iOS
Adobe Reader for Android
Adobe Reader Touch for Windows 8
In addition, the Reader mobile products do not open multiple windows/documents simultaneously, which would make the navigation between PDF documents nearly impossible. (Once a hyperlink takes you to a different PDF document, you have no way to go back to the original PDF document.)
The only Adobe Reader product that fulfills your department's requirements is Adobe Reader XI (mostly for Windows/Mac desktop/laptop computers). Acrobat Pro and Standard are paid products.
Because you are in search of a less expensive device for your department, you could get a Windows tablet instead of a Windows desktop/laptop computer. Microsoft Surface Pro (that you've mentioned in your previous reply) is just one example. You can also find other less expensive Windows tablets.
Tablets
However, please keep in mind that there are two different types of Windows tablets running two different operating systems.
(a) A Windows tablet with an Intel-based processor running Windows 8.1 Pro
Example: Surface Pro 3
You can install and run traditional desktop apps (e.g. Adobe Reader XI) and new Windows Store apps ("Modern" or "Metro-style" apps).
(b) A Windows tablet with an ARM-based processor running Windows RT 8.1
Example: Surface 2
You can only install and run Windows Store apps (e.g. Adobe Reader Touch) but not traditional desktop apps like Adobe Reader XI.
In general, type (b) tablets are more affordable than type (a) tablets. However, if you want to run Adobe Reader XI, you do need to check the technical specification of each tablet and make sure the following conditions are met.
Processor: Intel
Operating system: Windows 8/8.1 or Windows 8/8.1 Pro, not RT
Hope this helps you choose the right device for your department. Please let us know if you have any questions about system requirements or supported features in the Adobe Reader products. -
