I need help with vector shapes

I have created a shape with the pen tool in CS6, I have multiple shapes that I have built into what should be a single shape. Although when the path tool is not on I can see the single shape I can't seem to set a stroke to it which is an important part of the image design. Can anyone help please

If you can upload your PSD file and post a link to it so we can get what you have now. We can download it a show you what can be done. You see a path that has multiple closed sub paths is like a layer stack. Each segment is like a layer in a stack of layers and each layer has a mixing mode. Changing modes and order can radically change shapes the path will produce. Herr you see 5 paths all have the same sub paths but not not all have the same order and modes. The paths look different in the Path palette and the shape made with the are quite different.
How Photoshop stroke a shape often baffles me Sometime I feel the segment are missing or are extra and should not be there. Its most likely the stacking order and modes. I just can not seem to get a good mind's eye on the stack an modes. I know my brain must be defective in the perfect world how can that be????
Where is my stroke in this one I sure can not see it. All modes are subtract so Adobe subtracted the stroke I would guess...

I need help with the shape matching of this image

I am currently using NI Vision Assisstant to help me with the logic for the VI code. So currently I have 3 diagonal rectangles and I cannot figure out how to find the shape of each of them. Attached is a screenshot of the image I have. I have it going through a Luminosity filter and then a frequency filter and then I converted it to a binary image... now I am at this point: If anyone could help me find the rectangles... that would be greatly appreciated. I am sorry for such a basic quesiton.
Thank you,

Hello Yousuf,
There are quite a few functions that you might find useful for locating rectangles in a binarized image. Possibilities include Shape Matching, Pattern Matching, Geometric Matching, Shape Detection, and more. The difficulty that you will run into is the fact that your retangles are not straight edged, but are also not curved edges. Many of the shape matching tools look for straight edges and right angles, which are not present in your image. As such, it may be easiest to first use edge detecting tools to locate your edges, then use measurement tools to calculate area or distance.
I played around with your image briefly, and was able to localize the edges to within an approximation. I used the Clamp (Rake) tool to achieve the edge localization seen in the attached screen shots. As you can see in ClampRect.png, the edge lines drawn aren't terribly accurate, but the other images show the points used, and with some playing around you should be able to find a better approximation of the rectangle edge. Hope this helps!

Need help with vectors

I'm creating Drink objects into my vector (I'm required to use a vector in my program). However everytime a new Drink object is created and added into the vector, the other Drink objects in the previous indexes are somehow made into aliases of the new Drink object. Can anyone help me with this? Here's the case statement in which the program creates a Drink object, parses it with a DrinkParser class, and adds it to the vector:
case 'A': //Add Drink
                              drinkInfoPrompt();
                              drinkList.addElement(DrinkParser.drinkParser(br.readLine()));
                              break;

Thank you very much for helping me. Here's my DrinkParser:
import Drink;
import java.util.StringTokenizer;
//=============================//
//Utility class for creating a //
//customer from an input string//
//=============================//
public class DrinkParser
     static String input, temp;
     static String nameOfDrink; //Drink's Name
     static String typeOfDrink; //Drink's Type
     static double costOfDrink; //Drink's Cost
     static Drink drink = new Drink();
     //Main static method for creating a new customer
     public static Drink drinkParser (String lineToParse)
          input = lineToParse;
          input.trim();
          StringTokenizer tokenizer = new StringTokenizer(input, ":", true);
          //If the first character of the String is not a colon,
          //then program will proceed to tokenizing the first and
          //last name.
          nameOfDrink = tokenizer.nextToken();
          nameOfDrink.trim();
          drink.setDrinkName(nameOfDrink);
          tokenizer.nextToken();//Skips first colon
          typeOfDrink = tokenizer.nextToken();
          typeOfDrink.trim();
          drink.setDrinkType(typeOfDrink);
          tokenizer.nextToken();//Skips second colon
          temp = tokenizer.nextToken();
          temp.trim();
          costOfDrink = Double.parseDouble(temp);
          drink.setDrinkCost(costOfDrink);
          return drink;
     }//end drinkParser method
}//end class

Need help with drawing shape and scrollbar

Hi everybody, I am newbie at java just started learning it. I have a few questions to ask.
1. Can anyone show me to how to draw a equilateral penatgon, octagon, ( 5-10 sized shape) with polar cordinate.
2. How to make the scrollbar back to their default state( work alone not together) after you use the "scrollbar1.setModel(scrollbar2.getModel())" method. For example I only want the scrollbar to work together when I choose circle as a shape after that I want the scrollbar to be back to normal when I pick another shape rectangle for example. When the scrollbar work together, how do I the make it so that the scrollbar move from bottom to top for vertical bar and from left to right for the horizontal bar when they work together instead of the default bar move from left(0) to right(max) for horizontal bar and from top(0) to bottom(max) for the vertical bar.

So I am not asking you to do the work unless you really feel giving :)
This is my task for class..."Redo the programing example Election results so that the names of the candidates and the total votes are stored in Vector objects"
How do I store them in a vector object. An example would be nice but if you can't help then please keep comments to yourself unless they are constructive.

Need help with Vector problem

I'm creating a vector from a recordset, which i will use for paging purposes. I searched the posts for this but didn't find any good answers. Anyway, here's what I have. It's all in the JSP page (at least for now):
     Vector dataVector = new Vector();
     Vector rowVector;
     ResultSetMetaData rsmd = rset.getMetaData();
          int count = rsmd.getColumnCount();
               while (rset.next() ) {
                    rowVector = new Vector();
                    for (int i = 1; i <= count ; i++) {
                         rowVector.addElement(rset.getObject(i));
               dataVector.addElement(rowVector);
%>
// HTML STUFF
<%
for(int a = 0; a <= dataVector.size(); a++) { %>
<p> <%= dataVector.elementAt(a) %> </p>
<% } %>
And I get the following error:
java.lang.ArrayIndexOutOfBoundsException: 2 >= 2
     at java.util.Vector.elementAt(Vector.java:417)
     at org.apache.jsp.untitled$jsp._jspService(untitled$jsp.java:116)
     at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107........
I'm selecing 3 columns from the DB table, for a total of 2 records pulled (It's a test platform). So, any ideas?
Thanks
Mike Gernhardt

size will return the total number of objects within the vector and not the max index of the vector.
a <= dataVector.size(); a++) { %>
will obviously throw a runtime exception(
java.lang.ArrayIndexOutOfBoundsException)
making it a<dataVector.size(); a++) { %> will take care of the problem.

I need Help with a website I've created

I need help with a website I've created (www.jonathanhazelwood.com/lighthouse) I created the folowing site with dreamweaver at my current resolution 1366 by 768. Looks great on my screen resolution but if it is viewed on other resolutions the menu moves and some of the text above and below. How can I keep all content centered and working like it does on 1366 by 768 on all resolutions. The htm to my site is below I started off with a blank template through dreamweaver CS5.

Look at all the apdiv's you have. Those are absolutely positioned layers. I'm assuming by your post that you are very new to Dreamweaver and HTML and CSS. I would highly recommend not using absolutely positioned layers until you have a better grasp on HTML and CSS.
Looking at your code I would suggest that you consider using one of Dreamweaver's built in, or downloadable templates as a starting point and work from there.

Need help with Berkeley XML DB Performance

We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
          XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
          xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
     XmlIndexSpecification spec = container.getIndexSpecification();
     // ids
     spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // index to cover AttributeValue/Description
     spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
     // cover AttributeValue/@value
     spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // item attribute values
     spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // default index
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // save the spec to the container
     XmlUpdateContext uc = xmlManager.createUpdateContext();
     container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
     No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav

Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query     { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.

I need help with tracking

Ok the video that you can see on my youtube is the one I need help with. The video is actually in 1080p and I have no idea why it is showing in such a low resolution, but that is not the problem. I need to track the gun and add a null to that track, after that I want to add a red solid layer and bring down its opacity a little, to simulate a laser sight from the gun.Then I tried to parent and SHIFT parent the red solid to the track, the end product would have to look like what you can see in the picture. I have watched a TON of videos about tracking and just can not the the result I need. the laser needs to follow the gun as I aim up and bring the gun down. How should I do this.......? Please someone help or link me a tutorial that will be helpful.....

You have a couple of problems. First you don't need to use shift parent, just parent. Second, your red solid is a 3D layer and you have applied 2D tracking info to the solid. Actually, there's another mistake and it is in the tracking. You should also be tracking scale because the gun moves from left to right as well as up and down. This changes the distance between the front and back tracking points.
My workflow with this project would be:
Track Motion of the front and back of the gun including position, scale and rotation
Apply the track info to a null called GunTrack or something like that
Add a solid and apply the beam effect or mask the red solid to simulate the shape of a laser sight
Change the blend mode of the solid to ADD
Move the anchor point to the center of the starting point of the laser
Parent the solid to the Gun Track null
That should do it.

Need help with a currently "in-use" form we want to switch to Adobes hosting service

Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of. I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit" issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
I need to get this right and working for the majority of my users and on any platform and OS.
You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
(and you will probably get right to me, unlike my and I'm sure most other folks', "Adobe phone-in experiences")
Thank You,

Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
So I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself, I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products" to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi & so on)...and if you are still on my site.. go to any "GO RIGHT TO OUR ORDER PAGE" button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is, how do they select their individual colors within that (whatever) pack?... .
So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
So after thinking this all out, and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year, I think...its called http://pdf-fillableforms.com/.
A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however, if you're on MAC OSX or similar...
I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending" with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly, and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add).., except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form.... Many folks report to us the following issues that we know of. First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
It almost always generates some kind ( at least one time) of "error message" which we do warn them about..., telling one, basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it... and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly, the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4) If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that? Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...

What's the problem you're having ???
PS.

Need help with trim and null function

Hi all,
I need help with a query. I use the trim function to get the first three characters of a string. How do I write my query so if a null value occurs in combination with my trim to say 'Null' in my results?
Thanks

Hi,
Thanks for the reply. What am I doing wrong?
SELECT trim(SUBSTR(AL1.user_data_text,1,3)),NVL
(AL1.user_data_text,'XX')
FROM Table
I want the XX to appear in the same column as the
trim.The main thing you're doing wrong is not formatting your code. The solution may become obvious if you do.
What you're saying is:
SELECT trim ( SUBSTR (AL1.user_data_text, 1, 3))
,       NVL ( AL1.user_data_text, 'XX' )
FROM    Tablewhich makes it clear that you're SELECTing two columns, when you only want to have one.
If you want that column to be exactly like the first column you're currently SELECTing, except that when that column is NULL you want it to be 'XX', then you have to apply NVL to that column, like this:
SELECT NVL ( trim ( SUBSTR (AL1.user_data_text, 1, 3))
            , 'XX'
FROM    Table

I need help with resetting my ichat. When i try to login now it wont let me... it says "AOL Instant Messenger password" and then "iChat can't log in to ... because your login ID or password is incorrect. How do I reset this if I cant log in?

I need help with resetting my ichat. When i try to login now it wont let me... it says "AOL Instant Messenger password" and then "iChat can't log in to ... because your login ID or password is incorrect. How do I reset this if I cant log in? When I try to press online the same thing pops up and I have no way of logging in or asking for help.

Hi,
iChat (it would help to know which version) can accept Apple IDs as valid AIM Screen Names.
However if you have iChat 5 or earlier you cannot use ones ending in @me.com or @icloud.com issued by iCloud. (they can be used in iChat 6 or Messages as these versions make a double login to AIM and Apple to allow the use of the password).
In addition if you are using an Apple ID for an AIM Screen Name the password still needs to keep to the 16 character limit that AIM has.
AN @mac.com name can be used on any version of iChat (Until the 30th June 2014)
As it does not need a double check with Apple you can use it to log in to the AIM Web pages
Login here with an AIM Name registered at AIM or and @mac.com name and see if you get any suspended account messages.
Sometimes account can be suspended. Usually because something has triggered the "Unusual Activity" item.
About a year ago many @mac.com users that travelled out of their own country found themselves suspended when they got home.
If the Name checks out of if an Apple ID the password in known to be 16 characters or Less then do this:-
In Lion upwards open a Finder Window and use the Go Menu whilst holding down the ALT key.
Select the Library that appears in the menu list.
Navigate to Preferences.
(If you have version earlier than Lion the just navigate to ~/Library/Preferences (that's the Library in you Home - Little House icon - folder)
Fnd com.apple.ichat.aim.plist (even if you are using Messages)
Drag the file to the Trash and Restart the app.

Need help with Airport Express and so on.

Ok so my main problem before getting into what I need help with here is that our MacBooks and now my iPhone 6 plus isn't staying online. Keep getting booted off and then I either have to select the network again or it will eventually go back on. If anyone has a solution or so please feel free to answer that as well. I'm running on Roadrunner with a Netgear 600 wireless router and a motorola modem. Both of which I'll leave the link to below for a better look.
My Main Question: So I'm looking at a new wireless router mainly and possibly a new modem. I know Apple products are trustworthy but how good is the Airport Express and other Airport products. Also what is the Maximum speed and Maximum data speed for the cheapest express station and if anyone knows the speeds of the other devices it would be greatly appreciated.

DSL Router to Netgear 5-port Switch and I used the switch to connect to Airport Extreme, TV, Blue-Ray DVD player and DirecTV Receiver.
The AirPort Extreme base station (AEBS) is a router so it will do what you need.
You need to reconfigure your setup. Connect the WAN port of the AEBS to the DSL router. Then connect the Netgear switch to one of the LAN ports on the AEBS. The AEBS will properly share the connection.

I need help with shooting in my flash game for University

Hi there
Ive tried to make my tank in my game shoot, all the code that is there works but when i push space to shoot which is my shooting key it does not shoot I really need help with this and I would appriciate anyone that could help
listed below should be the correct code
//checking if the space bar is pressed and shooting is allowed
if(evt.keyCode == 32 && shootAllow){
    //making it so the user can't shoot for a bit
    shootAllow = false;
    //declaring a variable to be a new Bullet

USe the trace function to analyze what happens and what fails to happen in the code you showed. trace the conditional values to see if they are set up to allow a shot when you press the key
