How to deal with a large project (perhaps using the Daisy Trail Approach)?

Hi,
My intital problem was that I needed the screen to pause so that the user could interact with the spry menus and image maps. In other threads, I noticed that you added click boxes to prevent the screen from moving on. However, whenever I clicked on the spry menus or image maps, the screen moved on without giving me the chance to interact more on the screen. Furthermore, the screen faded away to white. I decided to use the timeline and make each slide last for at least 60 seconds. However, whenever I tried to do this for the entire project, it crashed, repetitively, The project has become too big - it is 164 slides.
I read in another thread that you can break the project up using the 'Daisy Trail' Apprach. When one chunk of the project finishes, you can execute another swf file to open and so on until they all open in sequence. I am wondering, how does this approach work exactly and will I still be able to use spry menus, i.e. will I still be able to insert links to the other parts of the project? Or does this approach mean that I must create a web page in order to add the links of these separate swf files and will this also make my spry menus and design defunct?
Any help on this would be greatly appreicated.
Many thanks.

Hi,
If I can prevent the screen from fading away whenever it pauses, I think that would be a good start (as you suggested). I tried this before, having read other threads but am having the same problem - it still fades away. I have done the following:
In Preferences, Defaults, I have commanded the objects to display for rest of slide, and for the effect to have no transition.
In Prefererences, Start and End, I have deselected the fade on first and end slides.
When I right-clicked on the actual slide, and tried to select Transition, No Transition, nothing happened. It wasn't even possible to select this option or the others from this menu. No tick was shown to show that it was selected.
Is there anyting else I can do or something I'm doing wrong? Thanks for any help!

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map

Dealing with two email accounts that use the same SMTP (outgoing) server

Folks:
re:   mail.app 5.2 (MacOS 10.7.4) with respect to POP accounts only
I've read this thread multiple times, spent many hours experimenting, and my web searches haven't come up with any more useful help.
How do you persuade mail.app to accept settings for two similar, but distinct email accounts that use the same SMTP (outgoing) server?   Say, the accounts are "blue.example.com" and "[email protected]". These have different user names and passwords.   The SMTP server is "smtp.example.com".
I think this is the appearance of success: the SMTP Server List (as seen in edit-the SMTP-Server-List mode) shows:
Server Name                   In Use By Account
    smtp.example.com      [email protected], [email protected]
(Description column omitted for brevity. And of course, mail.app doesn't show the little envelope icons.)
But I cannot reliably achieve this result.   When I select the SMTP server from the list for the second account --as suggested in the above-referenced thread--- I see the credentials (user name and password) for the first. Should I overwrite them? No, I don't think so -- I think that will break the first account.   I feel mail.app should present me with empty credentials boxes instead. Maybe this happens -- sometimes. But I can't see how to make it happen. Am I simply overlooking something?
A slightly different way of asking about this issue:   Suppose I manage to do a proper setup for the two accounts and they work. Then I change the password for "[email protected]" on the server. What is a reliable way of reaching the SMTP credentials for that account to make the edit? Same question for "[email protected]"?    Even when I successfully attach two accounts to one SMTP server, I seem only able to reach the first listed one to make changes. (In this case, "blue.example.com").
It is possible I'm missing something incredibly obvious...    I know the credentials for each account are distinct, but maybe mail.app copies them from the POP (incoming) settings.   Nah, that can't be, can it?   Or what?
Maybe I'm seeing bizarre things due to scrambled mail.app preferences. I've seen it before on other apps: delete the current preference file, get an auto-generated fresh one, and sanity returns. But with mail.app, with the prospect of losing years of emails --yeah, I've done it-- I'm extremely reluctant to mess around.
Suggestions, please.
TIA
Message was edited by: Hen3ry to clean up the table a little and add a parenthetical explanation.

OK, I'm convinced.   The mail.app UI is BROKEN -- in my primary user account. Such that it cannot reliably select an outgoing server for editing.
I created a new user account and installed some relevant example accounts in mail.app in that account. No problem. Well, a bit obscure, but still fully logical and reliable selection of individual SMTP accounts for editing.
For the sake of clarity, I think it is best to mark this "answered" and repost, focusing on the symptoms and asking how one might go about repairing the problem. So I'll do that.

How to Deal with a Large Form

Hello all. I have created a very large form using LiveCycle, which utilizes quite a bit of scripting. Unfortunately, as more and more data is added, the form becomes slower and slower, to the point where a user spends more time waiting than actually filling out the form. This is clearly unacceptable, so I'm looking to remedy this. One thought I had was to split the form up into several sections (the format of the form allows this without trouble). I have a few concerns related to this. First, for the people processing the form on the receiving end, processing several forms instead of one is several times as much work and several times as much of a hassle. Second, it is clearly less convenient to distribute several forms than it is to distribute one, so if I were to do this I would be looking for a way to bundle them together (perhaps a PDF Portfolio?). Third, for ease of use I would want to find some way that a user could simply click on a link (or button or whatever) to move on to the second form after finishing the first. If there were some way to combine the separate parts back together after they had been filled out and submit them as one entity, that would seem to solve the first problem, but I have no idea how one might go about doing that. As I mentioned perhaps a PDF Portfolio is the solution to my second question, but I've never worked with those and don't know if they would be suitable. Of course, if there was a way to speed up this form directly that would solve all of these problems in one fell swoop. If anyone is willing to take a look at this form I'd be glad to e-mail it to them (I don't feel comfortable posting it in a public location at the moment).
Thank you all very much.
===========================================
Update: I just read a different post below about the "remerge" command causing a form to slow down. I used xfa.form.recalculate(1) all over the place in my form. Is it possible this is causing the slowdown?

Send the form to LiveCycle8@gmail,com and I will have a look when I get a chance.

How to deal with OpenCL grey out issue.

First off, I'm not native english speaker.
I have Nvidia GeForce 550 Ti video card, and its support OpenCL v1.1.
I'm also face a "random" OpenCL grey out issue like other people here, but I found the "issue" and how to deal with.
open a command windows (using WinKey + R, and type cmd <enter>)
type "cd C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)" <enter>
type "sniffer_gpu" <enter> -->> to check your GPU has OpenCL in Photoshop?
When GPU is in power-saving mode (core running in 51Mhz, using MSI Afterburner monitor), I running sniffer_gpu, got this report
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>sniffer_gpu
Device: 0000000000328D68 has video RAM(MB): 1023

Then, I switch GPU back to normal status (core running at 900Mhz)

OpenGL ok
OpenCL ok, version=1.1 CUDA 4.2.1
Return code: 3
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>
OpenCL support !!
Nowadays, most of new GPUs were support power-saving, but when sniffer_gpu running at GPU power-saving state, the OpenCL computing report maybe "time-out", cause the detector "guess" the GPU does not support OpenCL. This is why many people says "OpenCL" sometimes work, sometimes grey-out.
I hope this bug can be fixed, or at least people can understand how to "enable OpenCL everytime when you launch photoshop".
Bye.

How to deal with visession in IVI-C driver program ?

a ViSession is an identifier that corresponds to a session.
My instrument is a remote internet device . i can call VISA library to implement
communication between labwindows and my remote internet device.In this case , what is meaning of Visession
? It looks as if Visession does not have a relation to my IVI-C driver program.
if it has a relation to my driver, how to deal with the ViSession in IVI-C driver program?thank you

ViSession is necessary as part of a larger picture and fills an important role in good architecture. Intrument handles (stored as the ViSession type) are necessary for large projects, which may require commanding multiple instruments.
There is no function to call which can get or set a ViSession value, similar to the way other attributes are set with driver functions. The ViSession intrument handle is created and returned to the application when an instrument is initialized; it represents a connection with one particular instrument.
This allows users to have multiple instruments connected, which can be controlled programmatically with one application. Then, the application can quickly specify which instrument it would like to send a command, just by sending one instrument handle or another.
Yes, you could remove the ViSession as parameter in your functions, but it would cripple the big picture effectiveness of the driver. In place of the ViSession, you would have to send each function the Resource Name or Resource ID for the particular instrument as well as the Option String. So really, it is just more practical and better practice to use an instrument handle (stored as the ViSession type).
That being said, for certain functionality (adding two numbers), you absolutely do not need a ViSession instrument handle parameter. You will have to use your best judgement to determine where to include or exclude this parameter. I suggest using the ViSession instrument handle parameter with any function that communicates with an instrument.
Also, Ebalci is correct regarding the difference between ViSessions and channels. ViSessions are used to communicate with different instruments. To reference or read a specific channel from an instrument you will have to refer to the guidance in the manual for the instrument in question. There will likely be a command to select a specific channel when reading from the instrument. And for general guidance, I suggest reviewing another IVI driver, possibly for an instrument of the same class or type or maybe from the same family, if such a driver already exists.

Hi Paulbin,
Do you want to supply a function-pointer to a DLL so it can call[back] your VI? Here's how it can be done with .NET, though, that solution requires a C compiler. A single "VI_to_function-reference" utility could handle all cases where the callback passes no parameters. Maybe someday somebody will share that dll.
Did you know that LabVIEW can use Events for some COM-signals change? See pic. (Note: DTR is not listed - - )
Another question is another function's prototype is WORD SetTestType(WORD comHandle, bool type1, bool type2, bool type3), I tried to use a boolean control and a Boolean to (0,1) node in labVIEW to pass parameters to CLF, I config the bool input value as U8(according to C++ bool type) and U32(according to WIN32 BOOL type), it dose not help, when I execute the VI, LabVIEW will be disappeare, it seems to be closed, I must start it again.
Could someone has similar experience on this points?
It's easy to crash LabVIEW misusing CLF - maybe there's another reason for the crash besides bool mis-match(?) Do you know which "Calling convention" is required? What type is comHandle? (where does comHandle come from?)
Cheers!

How to deal with "Error 1001. The specified service already exists" when install a service using installer package?

Hi everybody,
I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
Setup Project to install it.
Here is what I did for the "Class Library":
1. Finish the program.cs, Service.cs
2. Add Installer
3. Change the serviceInstaller so that "StartType" to be Aotumatic
4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
5.
6. Click in F5 (Start Debugging)
Here is what I did for the Setup Project:
1. Add the exe file built from the "Class Library" project to the Application Folder
2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
3. Change the property of the project so that "RemovePreviousVersion" to be true
4. Click on F6(Build Solution)
Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
1. After unstall, the registry was not cleaned up about the installed program
2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
My questions are:
1. How to cleanup the registry when uninstall a program?
2. How to deal with the "Error 1001. The specified service already exists"?
3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
Thanks a lot!

Hi Simon, not a problem!
I spent some more time on this and here are few more notes:
it is called Major Upgrade, when you are installing new version of the product upon a previous one and
MSI supports 2 strategies:
Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
installed files)
Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
will be reverted to the previous state and it'll be still functional.
Let's consider both strategies:
Consider you have installed product_v1.msi and you want to install product_v2.msi.
Strategy 1
1. MSI engine copies files from Product_v1 directory to TEMP directory
2. MSI engine merges files based on the assembly version (between v1 and v2)
3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
Strategy 2
1. MSI engine tottaly removes all files from v1.
2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts allready worked out and MSI doesn't have files to revert machine back
I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
here. So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
AND, you got "Error 1001. The specified service already exists"
because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
installation and they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
and delete), like this:
*clip*clip*clip*
' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
' Update the Service Entry to stop and delete service while uninstalling
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
' Update the Service Entry to stop and delete service while installing
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
*clip*clip*clip*
We can uninstall service first by following Strategy 2, but then we lose transactional support.
So, Simon did I encourage you to change your code a bit?:)
And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
Hope it will help to everybody!
See also more advanced explanation of how MSI works
here.
Truly yours, Marat

Should I add a lot of delete commands in the code for each table?Uh, well, yes if you continually add rows to a table the table will grow ... sooner or later you will want to delete rows that are no longer needed. What did you expect? You have to decide what the business rules are to determine when a row can be deleted, and make sure your design allows for such rows to be identified. This is called ..... analysis and design.

How to deal with this problem?

How to deal with this problem?
We plan to use Oracle Coherence (In Memory Data Grid) for a large-scale application. In order to keep the database table data in Coherence caches, we will create all the corresplonding Java objects (entities) and construct the persistence system using JPA/EclipseLink+JDBC. In this way, any in-memory object update will be persisted to the corresponding database tables.
The problem is that some existing application codes are updating these database tables directly now. If the direct-database-table update is not permmited in the persistence environment, we have to discard most of the existing application scripts.
I want to know, in this situation, should I discard most of the existing scripts?
Are there any other solutions?

Allowing writes from both cache & DB is possible with its own set of issues.
The main issue to consider is conflicts from updates on same record via both cache and DB. If your caches are write-through the conflict decreases - but then cache writes become slower. If your caches are write-behind potentially the older cache update will overwrite the latest DB update. Now you are back to Database 101 -- timestamps, versions, etc...
If you use a DB trigger to initiate the resync request you might want to distinguish whether the update has come from the cache-store (in which case, you may choose to do nothing), or if the update was from the 'existing apps', etc...
If you choose to inject the resync logic at the application code level - you have the usual sourcecode issues - can you modify the code, is all the DB code localized, what options do you have to link with Coherence functionality (DLL, external proc, webservice, etc), etc... Naturally though, if you have to make substantial changes to signal a resync....you might consider taking the extra step and change the code to write to the cache.

How to deal with relation

Hi
I am trying to import two beans(TestBean and HelperBean)into my Web Dynpro project to create a model. These beans are dealing with a List(ArrayList). This List is considered as a Relation. I am facing problem in handling this relation.
I am having both the TestBean and HelperBean in the same package. Below is the code of TestBean. This bean is in turn calling HelperBean ,which is returning a List.
I am getting an error while creating model -
[Error]: There are one or more relations unresolved. Importing the model without resolvoing the relations might result in erratic output.
Code For TestBean
public class TestBean implements Serializable{
 private List customerList= null;
 HelperBean helper = new HelperBean();
 public void execute(){
 try{
 customerList = (ArrayList)helper.getCustomerList();
 catch(Exception ex){
 ex.printStackTrace();
 * @return
 public List getCustomerList() {
 return customerList;
 * @param list
 public void setCustomerList(List list) {
 customerList = list;
I am new to Web Dynpro and don't know how to deal with relation.Please inform if there is some solution.
regards,
Sujit

Sujit,
Not every bean becomes model class during import. So your HelperBean is irrelevant here. But you miss other bean, namely Customer bean. You must add it as model class during import, then select problematic 0..n relation and resolve it to model class Customer.

How to deal with images when detecting/resizing screen?

Hi there,
I am trying to learn how to detect screen resolution and
resize a flash movie to those dimensions. The one thing I'm
wondering first is, how to deal with images in the movie.
Do I need a variety of different movie sizes that I serve up
depending on the resolution, or is there some way of linking to
higher rez image that can be scaled down to fit the screen?
Thanks!

as far as I know this has always been a bit of an issue when
using
images inside a scaled movie. If you display a high res image
inside a
scaled down movie, flash can't "reoptimize" it so the image
looks
jagged. Of course the other way around is even worse..
Serving images based on the screen res could be possible if
you detect
it using javascript but could be a night mare to maintain and
test it...
I guess the questions I would ask myselkf are:
1. what is my audience? What resolution the majority of them
will have?
2. Is there anyway I can keep the image size fixed, and scale
to fit he
rest of the design?
3. How much time do I have to implement the customized
version?
It really depends on your project..but to answer to your
quuestion yes
you can detect.
http://www.pageresource.com/jscript/jscreen.htm
and your flash will have to interpret and load images from
different
directories based on the var passed

How to deal with the rule that do not use "object" class to declear a class

I run my flex project in sonar. And there is a rule "Do not use Object class ".
I just want to know how to deal with this problem.
I mean, when I try to write a base class, I don't know which kind of class will be transfered in by reference, which type I can declear instead of "object"?

Check out this example:
The moment I put in the code >> box1.addItem("hello"); << and run the application, the BusNameListener is fired. Hope this makes sense.
import java.awt.*;
import javax.swing.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class JFrameExample {
private JComboBox box1;
public JFrameExample() {
box1 = new JComboBox();
box1 .setMinimumSize(new Dimension(300, 24));
box1 .setPreferredSize(new Dimension(300, 24));
box1.addActionListener(new BusNameListener());
box1.addItem("hello");
JFrame f = new JFrame("This is a test");
f.setSize(400, 150);
Container content = f.getContentPane();
// content.setBackground(Color.white);
content.setLayout(new FlowLayout());
content.add(box1);
f.setVisible(true);
class BusNameListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
JComboBox cb = (JComboBox) e.getSource();
String item = (String) cb.getSelectedItem();
if (item != null) {
JOptionPane.showInputDialog(null,
"Specify...", "File Import",
JOptionPane.OK_CANCEL_OPTION);
}
