Few Questions (Help Needed)

Hi,
I had few questions regarding captivate 4. If anyone can help, I would really appreciate it:
1) I created an eLearning project and it has some quiz sildes in them. So how do I collect the scores of the users who will go though that eLearning? ( I googled it but in most of the webpages they say just put a tick on report answers and also in the preferences enable reporting for this project) I tried using that but can`t see how to fetch the score for each users.
2) In the same eLearning I want to get feedback from the users who watch the eLearning. So basically I want a slide in which users can type in their feedback and then when they hit the submit button that feedback should be sent to a specific email. ( For this I tried using text box entry but all the text we enter in that comes in one line, we can`t press enter to change lines, also in the button I assign it to send an email to my lotus notes email id, but when I preview the project and click the button, it opens my lotus notes and it does not fetches what I have entered in the text box)

Hi there
You need to be investigating another piece of software that works in conjunction with applications like Adobe Captivate. Generically it is known as a LMS (Learning Management System).
There are tons of them out there. You might begin by looking at the link below:

About Java 2 opaque font color question, help needed!

About Java 2 opaque font color question, help needed!
I was trying to test opaque font (the string has a foreground color and a background color), but i can't find the method for doing that.
i can change foreground by Graphics2D.setPaint(Color.black).
Anybody know how to change the background of the string?
Thanks!

Hi. The way I'd do it would be to use the font metrics to find the length of a string and draw a rectangle and then drawstring over the rectangle. If you want an example, I can post it although I suspect theres a better way.

Adobe Lightroom 4 - Some Questions / Help Needed

Hi everyone.
After advice from several experts, I've just purchased Adobe Lightroom 4. I've already got Photoshop CS5, but I was looking for something proper to organise my photos, plus I found Lightroom easier to do the sort of editing I am wanting to do. Now, I only really use photoshop for things like colour pops, or really in-depth editing. Anyway, I'm loving Lightroom so far, but there is some stuff I'm not very sure of, so I'd appreciate some help
1. Organising
Firstly, I'm not really sure how to organise. At the moment, I've just got lots of folders with random events in My Pictures on W7, so I might have a folder called April 11, which contains photos from that month but that might have been a wedding or an easter holiday or both. So it doesn't really work. \
I understand in Lightroom what catalogs are. But I know enough to know that I don't want to group mine into those, its getting too complicated. What I don't know though is the difference between a collection and a folder. Basically, I'm wanting to reimport and reorganise all my photos, so I want to put them into "events" as such like you can do on iPhoto on a mac, so I would have "France Summer Holiday 11" for example, or "Mia's Wedding". I'm not really sure on the best way to do this ...?
2. Editing
I've played around quite a bit so far, and I really like what I've seen. On a lot of photos, I've made a lot of changes. But from what I can see, these changes are stored merely in Lightroom itself. For example, at the moment I'm importing photos from my external disk into Lightroom, which then saves them in C://My Pictures/Lightroom/Pictures . When I go look at these photos in windows explorer which I know I have edited, it doesn't show any of the changes or editing I've done on them. Now I realise this is me being stupid, but why doesn't it? Supposing I then want to email that photo to a friend that I have edited? How would I do that? I don't want to have to open lightroom and export every single photo I edit? There must be a simpler way?
Likewise for backing up, because all my files are in subfolders within C:// My pictures / Lightroom / Pictures, to back up I was simply going to set up windows to copy that latter folder onto my external HDD everytime I plugged it in. This would be pointless however if it isn't physically overwriting the original photo with my edited version?
3. Editing 2
Something else I like to do is make lots of different edits to the same photo. For example, at the moment I'm editing a photo of a pier at night. I spent ages adjusting colours and lighting and so on, and now it looks great. But I would also like to save a copy of that photo with the "old age photo" effect preset on. Is this possible? and how do I do it? Other than obviously importing a duplicate?
4. & 5. & 6 - Misc:
4. Simple question - how do I add tags, keywords or comments if I haven't done it on import?
5. My camera doesn't have built in GPS. Is it possible for me to manually geotag photos (in a batch, say for a Summer Holiday to NY), could I manually add a geotag for all these photos?
6. I also forgot to add copyright information on import for some, is it possible to do this after import and how?
7. I normally shoot in JPEG. I probably shoot shoot in RAW as everyone tells me to do so. Are there any significant advantages in terms of quality, and for editing with?
Thanks for any help given. I appreciate this is a lot of questions, but I could really use the advice.

Hi William,
1. Organising

I am not so sure if you understand *catalogs*.
You need a catalog, exactly 1 in my opinion. A catalog is a database. The Lightroom database, where records about your images are stored, including the pointers to your images, which are not inside a catalog! LR backups just does the backup of the catalog (i.e. a file ending .lrcat). You need to take care separately that your real images are backed up !
Inside your LR database the best way to organize is via collections - this will give you what you want with "France summer holiday 11" etc.
Folders are relatively unimportant, just storage buckets. They should be *handy portions*, I would prefer them with below 3000 images each, as there currently some bugs to those bigger ones.
Before you start with LR, you can organize your pictures in Mac Finder / WindowsExplorer.
Or you could do it with the help of LR, by copying your images over during import into the destination folders (and deleting today's folders afterwards after having verified that everything is fine).
A simple date-based structure will do, I'd recommend a root parent folder like "LR images", underneath one folder per year (\2010\, \2011\, \2012\...) and underneath them either
just one folder per month (LR can auto-create them for you)
or you create the folders in import dialog as e.g. "YYYY-MM-DD description of shoot", to have a mini-diary overview also in your OS.
Apart from that you create collections, either *dumb ones*, where you drag images into, or smart ones, where you specify criteria according to which they get auto-filled.
2. Editing

LR will never overwrite your original photos.
You can save most of the catalog content into the xmp-part of the original photo, which is either a sidecar-file (.xmp) or part of the file format, like for DNG, TIFF, PSD, JPG. To do so you select the image in LR and hit <ctrl> s. Or you set it up for continuous update, which creates a lot of operations while you play back and forth in develop.
I do that on my own, typically twice per file: once I am done with develop, once I am done with keywording and other metadata update.
LR contains records about your images, i.e. a set of instructions how they are to be interpreted. That is all.
So of course you need LR to export the result of these instructions, which is actually pretty quick.
To backup your images you need to do that just once, plus you backup your LR catalog. Or if you save xmp to the files, you can do another backup once xmp is ready.
I would not consider this pointless. You just have to think that there are 2 places with data for your images: the images themselves and a database with interpretation instructions.
3. Editing 2
Something else I like to do is make lots of different edits to the same photo. For example, at the moment I'm editing a photo of a pier at night. I spent ages adjusting colours and lighting and so on, and now it looks great. But I would also like to save a copy of that photo with the "old age photo" effect preset on. Is this possible? and how do I do it? Other than obviously importing a duplicate?
Yes, this is one of LR's beauties: you create a so-called *virtual copy*, which is just a 2nd record for the same original image file with different interpretation settings, like black-and-white, a different crop size, different development etc. You can have as many virtual copies as you like, and you'll see them as additional thumbnails.
Virtual copies are not saveable into xmp, though. There is another concept which is saveable into xmp: snapshots. but these are different states in develop history, and you do not see outside develop module that you have several.
If you export virtual copies e.g. to jpg one file per virutal copy will be created.
4. & 5. & 6 - Misc:
4. Simple question - how do I add tags, keywords or comments if I haven't done it on import?
5. My camera doesn't have built in GPS. Is it possible for me to manually geotag photos (in a batch, say for a Summer Holiday to NY), could I manually add a geotag for all these photos?
6. I also forgot to add copyright information on import for some, is it possible to do this after import and how?
7. I normally shoot in JPEG. I probably shoot shoot in RAW as everyone tells me to do so. Are there any significant advantages in terms of quality, and for editing with?
Thanks for any help given. I appreciate this is a lot of questions, but I could really use the advice.
ad 4: you use the library module, metadata panel to enter.
ad 5: you use the map module. Either you manually drop your images on a map, or you have a separate GPS track to load and have LR assign via matching time-stamps.
ad 6: like 4
ad 7: You don't need JPG from your camera, you can achieve better results viy LR from RAW. Yes, there are significant advantages as to editing headroom.
Overall, may I suggest my favorite learning material for LR? First watch Julieanne's Tutorial Videos.
Then go play and use Victoria Bampton's eBook or paper copy of her "Missing FAQs to LR4": http://www.lightroomqueen.com/books/adobe-lightroom-4-missing-faq/
Have fun,

I am simply don't understand any of it, however, according to the MOD I have been told 'there is no issue present.' Could someone explain some of the terms and what is actualy mentioned in the table above.
Expanding Wireless Range.
I am currently using BT Home hub 3
I have 2 powerline adapters ,so, from what I understand I can use a 'wireless access point'.
I am not sure whether if that is the right thing and even if it is, which one should I use with my BT Home Hub 3, any sugesstions.
I am currently looking at this guide: http://www.cbeddoe.btinternet.co.uk/wireless/wireless_boost.html
Would you recommend a different one, please let me know down below in the reply section.
Thanks

If you are looking for maximum speed wireless is not the best option a wired network will always be the best

A few questions, help is greatly appreciated

I'm in the beginning phases of starting my own production company. Video taping weddings and other special occasions. My question is with continuity. Say I shoot a scene with more then one angle, and there is music going on in the background. Do I need to purchase a switcher, or is there something on Final Cut pro that will help me with syncing clips from two different camera's perfectly?
Any links to helpful sites for starters? Thanks a bunch

But how do you make sure you have a moment that you can use to lock all the multi-cam video and audio into sync? Simple. Used an old tried and true method from film production.
Buy a clapboard and shoot a slate at the beginning of each reel of tape.
I use one that cost me $25 from a wholesale magic supply place. You don't need one of those expensive ones with the built-in timecode display. Just a simple old-fashioned clapboard works fine.
If you never have seen this done, someone stands holding the clapboard where all the cameras can see it (and the audio can hear it), you roll tape in all cameras and audio, then all the cameras and audio record the person snapping the bar of the clapboard down. This is called "a slate" or "sticks."
As I said, shoot a slate at hourly intervals to allow for simultaneous tape changes in all cameras. Once you start the cameras (and audio recorder, if are doing that too) rolling, NEVER TURN THEM OFF until it's time to change tapes. This way, you will be able to sync all audio and video to the event of the clapboard strike, and then have everything stay in sync for the duration of those reels.
Build tape change times into your shooting schedule, and remember to shoot a clapboard slate at the start of each new recording period.
Just like we use to shoot film in the old days. Same principle exactly. For you old-timers who remember, here's how we can mimic using "crystal sync" to tie all the speeds together in the digital age.
Run all cameras and audio recordings at 48khz, 16-bit audio settings to standardize sample rates, and therefore "speed." The camcorders lock their video "speed" to the audio sample rate. So if you have all the cameras set to record audio at 48khz, then that will lock all their video into recording at the same "speed," too. If recording separate audio into a computer or digital recorder, make sure you record it at a 48khz 16-bit sample rate, too, for all the same reasons.
When you then bring each roll of tape into FCP for editing, you will be able to find the frame where the clapboard bar hits the board. Drop a marker in that track. Then line up all the markers for all tracks from each camera and each will then be in sync time-wise with each other.
Do the same with the audio. You will be able to see the spike in the waveform when the bar hitquite clearly. Drop a marker. Then slip that into sync with the video. Voila! You have multiple cameras locked into time sync with each other, and with the outboard audio. As I said, just like we used to do with film in the old days.
This method works. I've shot several music concert shoots and some "instructional" programs that need multi-camera coverage this way. Eliminates the need for a switcher and all that stuff.
It works flawlessly. Just remember NEVER TURN OFF A CAMERA ONCE YOU START RECORDING AFTER SHOOTING THE CLAPBOARD until it's time for tape change. If you follow that rule, you will be fine.
If you do accidentally stop one camcorder during the shoot, just shoot "double-sticks" - have the camera that stopped and at least one that didn't shoot a second clapboard event. Then use that to pull the "orphan" video segment into sync with rest of the content. No worries.
This info should get you started down the right path.
Good luck in your venture.

Stupid Java Question (Help Needed!!!)

I have a piece of Java Code that dynamically builds a SQL statement (including VARCHAR2 columns). Oracle gives an error if my string has a single quote in it. I need to replace each single quote with two single quotes in Java, i.e. I need a Java equivalent of PL/SQL REPLACE function.
Java str.replace only replaces an individual character (see below).
String l_str = "O'Hara";
String l_str2 = l_str.replace('\'', '\'');
I need to replace "O'Hara" with "O''Hara". Any help is appreciated

Please don't post same question on both forums.

Beginner Question - Help Needed for EJB QL Sample Application

I'm working with a group of student interns, like myself, and we've been given an assignment to work with Oracle. All of us have no training or experience with this, so we're just learning as we go.
I've been trying to run the EJB QL Sample Application (http://www.oracle.com/technology/sample_code/tech/java/ejb_corba/ejbql/Install.html), but I keep running into problems at step 3.
Now, we will deploy the sample application onto OC4J. Open another command prompt and go to the folder <OC4J_HOME>/j2ee/home and run the following commands one-by-one
> java -jar admin.jar ormi://<machine_name>:<admin_port> admin <admin_pwd> -deploy -file <SAMPLE_HOME>/build/ejbql.ear -deploymentName Ejbql
> java -jar admin.jar ormi://<machine_name>:<admin_port> admin <admin_pwd> -bindWebApp Ejbql ejbql-war http-web-site /ejbql
where,
<machine_name>      Name of the machine where OC4J Server is running
<admin_port>      Admin Port on which the OC4J server listens. This value by default is 23791 unless explicitly changed by the user
<admin_pwd>      Adminstrator password to access OC4J. The default value is welcome
When I do this step I get this error:

George,
The Readme.html file is available with the ejbqlsample.jar downloadable (Extract and find the doc in Ejbql\docs\Readme.html) which is printable.
Or,
If you are trying to print the file directly from OTN site, you need to set the Page-Setup Orientation to 'Landscape'.
Hope this helps.

Question, I have just completed an audio presentation project (audio book on CD) for a client (681 mgs) which I now need to have replicated 1500 times over. The problem is my outsourced replicator will only press cd's up to 650 mgs. Therefore, I need to figure out how to compress the presentation just slightly (as to not lose tone quality) to get in onto the disc. (The CD Rom will be played in the car or computer Cd players)
I used the Soundtrack 1.2 to complete the project and also have Quicktime pro, however, I'm not sure what to do and how to change the settings to get the compression correct.
Thanks

Is it something you can simply save as an .aif file, then import it into iTunes and then compress it to mp3 at, say, 256 Kbps? That's pretty good... but if you're looking for better... perhaps an mp2? Not easy to find an mpeg1 layer 2 compression utility, but I use Sound Converter:

It's a start...

OAF page customization question - help needed urgently!

Hi,
To minimize customizations on an OAF page we are trying to handle some validations at the databse layer using a db trigger. The flow is that when the user hits Save on an OAF page and a certain column in a table is updated by the EO, a db trigger set on this column will fire off. Based upon whether the validation went through or not the db trigger might fail
with an error message. Question is will this message be displayed on the UI without any customizations so that the user knows what happened or will the OAF page just throw a null pointer exception? Also since OAF is writing directly to DB using an EO, will it be too late by the time the trigger kicks in and validates stuff and then based on if there was an error it rollsback the data? Can we rollback the entire transaction or not?
Please help!

Adding to Mukul's reply, yes if you are using OAF, let all the control be through the OAF. In your case any error in the DB will be sent back to the user in a very raw way which surely will annoy any user. Also we cann't comment on the rollback status.
My suggestion is to make use of a callable statement and call a wrapper pl/sql procedure which does all the validations for you (in case you have varied and complex validations) and returns a true or false based on which you can commit the transaction.

Stupid Question Help needed....

Hi Folks...
I have a very Stupid Question....
but i think you Folks here can help me Quick...
Here is what i want to do...
01 class ourCar {
02
03 public String color;
04
05 public void PrintValue(String YourValue){
06      System.out.println(this.YourValue );
07
08      }
09 }
10
11 public class myApp {
12 public static void main (String[] args) {
13
14 ourCar Car1;
15 Car1 = new ourCar();
16
17 Car1.color = "red";
18 Car1.PrintValue("color");
19 }
20 }
So the Compiling Problem starts at 05 it seems i cant
get Parameter Names with Strings... so what i want to do is...
type
Car1.PrintValue("color");
and it should print out red
i Know i could write
System.out.println(car1.color);
But i want to do it the other way...
a other thing would be to make
myVar = "car1.color"
and then run
System.out.println(myVar);
but these is also not working...
any idears?
greetings from munich
peter

but where is the Thinking Error i have?
KJKrum wrote i should not use the language this way...
what would be the right way for doing a job like this?You have a very simple example. Reflection which is what both threads suggest as a solution is complex and should be used with caution because of the performance and maintenance problems that can arise.
So one has to wonder, for such a simple problem, does it not suggest that perhaps your design is not correct and if you took another look at it you could come up with a solution that is more appropriate and leads to code with is much simpler.
I believe that was the intent of the suggestion.
For example if you really must access 'attributes' via a key then have you considered that perhaps you don't have attributes but rather 'properties'. And if so there is already a Properties class. And if the Properties class is a little to constraining then the Hashtable might also fulfill what you are trying do. Keep in mind that these depend on whether the best design for your project really requires accessing values via a string.

A few questions I need some advice with.

NOTE If you can put some source code as examples to answer some of my questions then that would be much appreciated.
1)
I know how to put an image on an applet but my problem is how do I put an image in a JFrame?... rather than just using the boring set background color options.Example I have matrix.bmp and I want that as my background image on my java application/frame how do I go about doing that.
2)
When I try the SCJP certification in x amount of time in the future, if I get a job as a Java programmer - would theye expect me to use a full blow API or IDE, or would theye just let me use a text editior?
The reason I ask that is because I preffer using a text editor and want to know if i'll have to learn how to use an IDE in the future.
3)
I cant seem to find a good native compiler! (I can use a search engine so no smart comments please) i've found two, one is useless and the one I found on sourceforge cant seem to find the correct compiler once I attempt to create a Java exe. (link me a freeware one if you can please)
4)
Is it possible to create a Jar file with anything other than an applet? i'm guessing you can but I keep getting a manifest error message... thus an explanation on why mine and a lot of other jar files (even in the java sdk) get that message and how to get around it.
I have some more questions about socks ect but i'll leave that for now.
Thanks in advance

They're both Containers, I believe
2)

The reason I ask that is because I preffer using a text editor and want to know if i'll have to learn how to use an IDE in the future.You may well change your mind about that when you've got a sizeable project to deal with!

(link me a freeware one if you can please)Re-consider your requirement to do such a thing. It rarely actually happens in the field, since exes aren't portable

Follow a simple jar tutorial - there are millions of them around - to see how to build a manifest file

Newbie questions, help needed, please

I am pretty new to Oracle Application Express. I have two problems when I try to create Page with type of "Report and Form". I hope you guys could help me out:
(1) When I create Pages with the type of "Report and Form", the first column, primary key does not show up in the report page. Why?
(2) When the table has two primary keys, I have problem when I click the button to go to form page from report page to update the record. It always show error said "Fetch returns more than one rows". How can I tell the application that I have two primary keys?
Thanks,
Lee

Put in "HTML Expression [Insert column value]" part of field which will be a link:
a href = f?p=&APP_ID.:&APP_PAGE_ID.:&APP_SESSION.::NO::PX_PK1,PX_PK2:'+'#PK1#'+','+'#PK2#')">Edit< /aput in previous sentence "<" in front and ">" on the end and remove blank before "/a" - otherwise you'll not see the content but real link!!!!!
where :
<li>"&APP_ID." is the page in which you want to open and start edit</li>
<li>"PX_PK1,PX_PK2" are items on that page (probably hidden) tha will represent primary key</li>
<li>"#PK1#" and "#PK2#" are primary key values on current page (from table grid represent with query "SELECT PK1,PK2,...from MyTable"</li>
P.S.
I read somewhere that life with Appex should be much easy when people should use PK base on one coulmn (sequence).
To ensure PK on those fields create UNIQUE index on those two fields and in table define NOT NULL on those two columns.
When you get expireienced you'll know the benefit of this advise

Simple question, help needed? Finder icons

In finder have lost the music folder on the left sidbar(the one beside 'pictures' and 'movies' etc..) how do i get this folder back with the nice default music icon?

Ribbs,
I should have paid more attention your original question.
Sorry for pointing out the obvious.
Removal and replacement of the Music Folder from the Sidebar on my system always results in the Treble Cleff icon representing the Music Folder. Seems like there might be some kind of cache or plist corruption problem with your system.
I would advise that you read, Maintaining Mac OS X and Running the Mac OS X maintenance scripts by Dr. Smoke for some troubleshooting tips.

Simple Array Question - Help Needed!

Hey people,
I need a line of code that gets the maximum value out of an array.
the array is called LEVELS and contains values [1, 3, 4, 17, 3, 2, 4]. I need a line of code that creates a new variable called MAXLEVEL and finds the largest value within the array.
Thanks,
sean :)

Create a variable. Initialize it to the lowest possible value, like say Integer.MIN_VALUE.
Loop through your array.
For each element, see if it's greater than the current value in the variable. If it is, use it.
When you reach the end of the array, the variable now holds the max value.
How did you think you were going to do it?
