Run-time app initialization?

We have a fairly complex Flash application which I want to
migrate to Flex. Its a real-time trading system consisting of a
couple of hundred classes. It is Flex-like in many ways... there is
nothing on the stage apart from the Main() class, the library is
nothing but components, almost all graphics skins are
programatically generated, we have always used an event dispatching
architecture, MVC and a layered approach to comms classes, which
means the design will translate well to Flex. One of the nice
things about it is the entire screen layout is defined through XML,
much like MXML.. Our screen building class goes through the XML and
instantiates all the classes it finds using the settings we define
through the XML. This means we can generate various versions of the
application, including localised, simply by getting the web team to
edit XML files. At runtime we pass a parameter to the app allowing
it to select the correct XML files and paint itself accordingly.
So to Flex... as I understand it, if we wanted to be able to
get initialization values at run time, we'd have to use the Flex
server, which generates the swf from the MXML and AS files on the
fly? (There may be resistance in the company to introducing another
technology on our servers, we have many servers in several
datacentres.) As far as I can see, the other choice is every time a
minor change is made in the XML, in terms of colours, sizes,
positions, etc, the app would have to be recompiled in Flex?
We would have to have a very simple MXML file which just
kicked off our screenbuilding class which would then read the XML
and instantiate classes, exactly how our current Flash app works.
Or is there a better way? It would feel a bit like re-inventing the
wheel. It would be great to know how others have approached this
issue.

I would think you could use run-time styles for this. XML and
css could provide configuration information, which could be loaded
at run-time.

App Builder/Run Time Install Broke?

I have full up version of LabView 5.1.1, running on Win98.
I went through the Application Building Example on page 12 of the
Application Buidler release notes.
I then installed the sample app on another Win98 box. The application
installation went OK until it ran the install for the LabVIEW runtime.
Then I got the following error:
"Setup Initialization Error
Setup requires a different version of Windows. Check to make sure that
you are running Setup on the Windows platform for which it is intended.
Error 102."
I also get this same error if I run the LabVIEW runtime install
directly.
As I said, both machines are Win98. I'm stumped. Any ideas?

I am not sure if this is your exact problem but you might try it . I found
with the run time in 5.1 would not install properly . On the target machine
I did a runtime engine install from the APP builder disk , not from the 5.1
disk . Then things seem to get sorted out after that . I still haven't been
able to do a stand alone disk that installs the runtime engine and
application together yet. More for the lack of trying after I got a work
around (I hope?) . That was with win95 and 5.1 , not sure if the same sort
of thing will be true for 5.1.1 and win 98.
Hope that helps

Error Running Oracle Apps and Discoverer at the same time

Hello,
We are having trouble running Oracle Apps and Discoverer at the same time on certain user's machines. Here are the specifics:
The user opens Oracle Apps in Internet Explorer. The user then opens Discoverer in another Internet Explorer windows and receives the following error: Runtime Error! Program: C:\Program Files\Internet Explorer\iexplore.exe abnormal program termination
As a work around, I installed Firefox on those user's machines. These users run Oracle Apps in Internet Explorer and run Discoverer in FireFox. This has solved the problem in 99% of the cases. However, there is one user who is having FireFox using Discoverer freeze when running Oracle Apps in Internet Explorer.
Can anyone provide any insight on how I can solve these conflict issues so users can run Oracle Apps and Discoverer at the same time?
Thanks in advance for your help,
Carlos

Hi Michael,
I agree with you completely. It is reccommended to run 10g on a separate physical server unless you have sufficient resources to run on the same server (which even most large clients do not) Even then, I would recommend a separate server.
I should have put my comment in context :-)
a.) I was only stating that it was possible
and
b.) whether 10g is installed on the same physical server or separate should not affect the client browser crashing issue that was posted.
I do have an install with EBS11i and Discoverer 10g on the same physical server and it works fine (this is sandbox/ TEST). Most of my large customers have 10g installed on multiple physical servers due to load balancing (capacity).
I do work for Oracle. I try to help out on the forum when I can, but it is hit or miss :-(
I would be glad to discuss anything privately.
As for the issue at hand, I can reproduce the problem and here is what is occuring.
I have EBS 11i configured with Jiniator 1.3.24
I have Discoverer 10g configured with Sun Java plugin 1.4.2_06
1. If you launch EBS 11i apps and a form with MS IE, then the browser launches the form using Jiniator JRE 1.3.xx (whatever you have configured in AutoConfig for EBS11i)
2. Next, the user navigates to EBS 11i SSWA and launches a Discoverer workbook.
What occurs is a child IEXPLORE.exe process is spawned from the parent IEXPLORE.exe process and Discoveer Plus is launched. The parent iexplore.exe process will be attached to the Jiniator JVM. Now if Discoverer is configured with
a.) Sun Java Plugin or
b.)a version of Jinitiator that is a different version from what EBS 11i is configured with
then you may get this conflict.
It really is an MS IE/JRE conflict with Jinitiator and Sun Java Plugi and the way the broswers attaches to the JVM (IMHO) as this behaviour could be reproduced with other non-oracle java applets.
You can workaround the situation by:
a. configure EBS11i and Discoverer to use the same version of Jiniator 1.3.xx
b. educate the users to open one MS IE browser to connect to EBS11i and then open a second MS IE browser to login to EBS11i SSWA or Discoverer 10g Plus directly to launch workbooks. They need to to this by clicking on the icon and not using File >> New browser. Clicking on the icon will spawn a new parent iexplore.exe process that can attach to a second/different JVM. File >> New Window will spawan a child of the parent.
c. As you did use two browser versions. MS IE for EBS11 connection and FireFox for Disocverer 10g connection.
I would choose optoin b, so that you can use Sun Java Plugin with Discoverer.
Open to any comments. I hope that helps you workaround the problem. The ideal solution is to have EBS 11i use/cerified with the 1.4 or 1.5 JRE. In poking around, I see there is a related post to this on one of Oracle's EBS 11i Product Managers Blog.

My executable compiled with Real Time Engine 5.1.1 in App Builder gives error when trying to run in App Builder with RTE 6.1

Hello. I built an executable using App Builder in LV 5.1.1 and now, years later, I am trying to run it in LV 6.1 but I get an error stating a requirement for Run Time Engine version 5.1.1. To be able to run this, must I install the older version of Run Time Engine? If so, where can I find the older version? Do I have to install the older version of LabVIEW to get the RTE? Will having both versions on my pc be a problem?
I assume that once I am able to run the exe, that I will be able to recompile with the newer version of the RTE using App Builder. Is this correct?
I have been away from LabVIEW for several years and am a bit rusty on these details that I once knew. Any help is appreciated.
Alex

The version of the run-time engine must match the version of LabVIEW that was used to create the executable. You can get any version of the run-time engine you want here. The only way to create a version 6.1 exe is to re-build it from the source code with diagrams. An exe has no block diagram so it cannot be converted to a newer version.

Mac Standalone LabVIEW App - Include Visa & LabvIEW Run-time

Hello All,
I've used LabVIEW for over a decade but only for Windows, just getting into LabVIEW for mac, so please pardon any ignorant questions.
I am developing a very simple project to be deployed stand-alone that needs LV Run-time and NI Visa. My project uses a simple USB-Serial device that I talk to using Visa. I used this link to package LabVIEW run-time with my app. I think I need to package NI Visa drivers as well. I am not sure how to do that. Anybody have any experience packaging drivers with stand alone apps for LabVIEW in mac? Thanks for your help.
Kudos always welcome for helpful posts
Solved!
Go to Solution.

Thanks, Silvia. This is a limitation and there are more and more developers on Mac OS. Can you provide answers for couple questions:
Any plans to include Installer App like how we have for Windows OS?
If [1] is not anytime soon, can NI provide a KB to deploy a stand-alone Mac app packaging drivers? I think this will be very valuable.
Kudos always welcome for helpful posts

Any possibility for loading and changing XFL/... data at run time of Flash app?

Hi everybody,
I have a quick and general question for the following case:
I want to produce some transitions and effects for a kinetic typography project in After Effects and then import these parts into Flash Professional via XFL and Bridge.
So my actual problem is this one: my Flash application should be able to load these made transitions and effects dynamically at run-time and not from a pre-configured timeline made upfront. Because there should be dynamic text fields in these XFL data from After Effects I also need to be loaded at run-time for the kinetic typography thing.
So is there any possible way to do / load / change the dynamic text fields in these XFL data or the order of all transitions and effects in Flash Professional at run-time or anything else?
I know this is a special question, but I hope there would be an answer...
Thanks for your help in advance

Where do you find the running time of TV episodes on the Itunes app?

I can't find it anywhere and if I can't find it, then I won't be buying it!

It doesn't show you running time on the mobile version of iTunes, it does show you on the OS X or Windows version.
I really can't speak for the other volunteers here but I think I can safely say we don't care whether you buy it or not.

JSP, Data Web Bean, BC4J: Setting the where clause of a View Object at run time

Hi,
I am trying to develop a data web bean in which the where clause of a View Object will be set at run time and the results of the query then displayed.
My BC4J components are located in one project while the coding for the data web bean is in another project. I used the following code bu t it does not work. Could you please let me know what I am doing wrong?
public void populateOSTable(int P_EmpId)
String m_whereString = "EmpView.EMP_ID = " + P_EmpId;
String m_OrderBy = "EmpView.EMP_NAME";
oracle.jbo.ApplicationModule appModule = null;
ViewObject vo = appModule.findApplicationModule("EMPBC.EMPAppModule").findViewObject("EMPBC.EMPView");
vo.setWhereClause(m_whereString);
vo.setOrderByClause(m_OrderBy);
vo.executeQuery();
vo.next();
String empName numAttrs = vo.getAttribute(EmpName);
System.out.println(empName);
Thanks.

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by JDev Team (Laura):
Here is how I have usually done mine:
1. In the JSP, use a RowsetNavigator bean to set the where clause and execute the query.
2. Use a custom web bean to process the results of the query (print to HTML).
for example:
<jsp:useBean class="oracle.jbo.html.databeans.RowsetNavigator" id="rsn" scope="request" >
<%
// get the parameter from the find form
String p = request.getParameter("p");
String s = request.getParameter("s");
// store the information for reference later
session.putValue("p", p);
session.putValue("s", s);
// initialize the app module and view object
rsn.initialize(application,session, request,response,out,"wt_bc_WT_bcModule.wtjoinView");
// set the where clause string
String theclause = "presname = '" + p + "' AND slideno=" + s;
// set the where clause for the VO
rsn.getRowSet().getViewObject().setWhereClause(theclause);
rsn.getRowSet().getViewObject().executeQuery();
rsn.getRowSet().first();
%>
</jsp:useBean>
<jsp:useBean class="wt_bc.walkthruBean" id="wtb" scope="request" >
<%
// initialize the app module and VO
wtb.initialize(application,session, request,response,out,"wt_bc_WT_bcModule.wtjoinView");
wtb.render();
%>
In this case, the render method of my custom web bean mostly gets some session variables, and prints various content depending on the session variable values.
Hope this helps.

Design issue with sharing LV2 style global between run-time executables

Hi,
Just when I though that I had everything figured out, I ran into this design issue.
The application that I wrote is pretty much a client-server application where the server publishes data and the client subscribes data using data sockets. Once the client gets all the data in the mainClient.vi program, I use LV2 style (using shift registers) to make the data global to all the other sub-vi’s. So the LV2 is in initialize mode in the mainClient.vi program and then in the sub-vi’s the LV2 is in read mode. Also, I had built the run time menu for each sub-vi that when an item is selected from the menu, I would use the get menu selection to get the item tag which will be the file nam
e of the sub-vi and open the selected sub-vi using vi server. This all worked great on my workstation where I have labVIEW 7.0 Express installed. But the final goal is to make exe’s for each of these sub-vi’s and install runtime on the PC’s that do not have labVIEW installed. Of course when I did that only the mainClient.exe program was getting the updated data from the server but the sub-vi’s were not getting the data from the mainClient.exe. I did realize that the reason for this is due to the fact that I had compiled all the sub-vi’s separately and so the LV2 vi is now local to each executable (i.e. all executables have their own memory location). Also, the run-time menu did not work because now I am trying to open an executable using vi server properties.
To summarize, is there a way to share LV2 style global's between executables without compiling all of the sub-vi’s at one time? I tried using data-sockets (local-host) instead of LV2 st
yle gloabls to communicate between the sub-vi’s but I ran into performance issues due to the large volume of data.
I would really appreciate it if anyone can suggest a solution/alternative to this problem.
Thanks
Nish

If the LV2 global is loaded statically into your mainClient.vi, then any
other application can connect to the exe and get a reference to the VI
using the VI name. This gives you a VI reference you can use to call
the VI. Ye
s, the values will be copied between applications. That is
why you need to add access operations to the global that returns just
the info needed. If you need the average, do that in the global. If
you need the array size, do that in the global. Returning the entire
array shouldn't be a common operation on the LV2 style global anyway.

Your app does need to watch both the amount of data being passed across
the network, and the amount being shared between the apps. You might
want to consider puttin
g the VIs back into the main app. What is the
reason you are breaking them apart for?

Can you please let me know what can be tried to fix this

Error involving Report Generation Toolkit and Labview Run Time Engine

Developed an application using LabVIEW 6.1 and LabVIEW Report Generation Toolkit for Microsoft Office 1.0.1. From there, tried to build a shared application for use with the LabVIEW Run Time Engine. The Run Time version functions properly until "New Report.vi" is called and then an error is generated, code 7, calling out "Open VI Reference in New Report.vi" could not be found. When building the application, I did include the "NI Reports Support" in the advanced installer options. The machine used for original development and application build is running Windows XP Pro and Office XP. Any suggestions??

I am having the exact same problem but with LV 6.1 and M/S WORD 2000. It appears that the "New Report.vi" is trying to open "C:\APP.DIR\Word_Open.vi" and "C:\APP.Dir\Word_Open_Document.vi" by reference. The "OFFICE 2000.TXT" says that "_exclsub.llb and _wordsub.llb must be added as support files when building an application or a dynamic link library with the application builder." I added them as Support Files and I copied them to the "C:\TESTER\" where the TESTER.EXE is and I still get ERROR 7 in "NEW REPORT.VI" at VI OPEN REFERENCE.
Do I need to make a "C:\TESTER\DATA\" sub-dir and put the support files there?
I am building on MY COMPUTER on F: Drive on a network and transporting files to the real Tester.
I displayed my App.Property of APP.DI
R at start up and it is C:\TESTER\ ! How would my application know that "Word_Open.vi" and "Word_Open_Document.vi" are actually inside the _wordsub.llb?
Any ideas ?

Adding complex computed column at run-time fails in PB 12.6

I support a large 'vintage' application that was originally written in the late 90's, and has been migrated from version to version over the years. Currently I'm working to get it working in PB 12.6 Classic, build 3506, migrating it from PB 11.5
The first issue I've come across is that PFC treeviews are not working properly. After some debugging, I determined that the cause of the failure is the PFC code's creation of 'key' column in the datawindows being used to populate each level.
In the pfc_u_tv.of_createkey function, it looks at the linkages between the levels of a treeviews data, and then crafts an expression, and then uses that to create a computed column, which is subsequently used to uniquely identify the data.
The expression is a series of string concatenations, such as this:
expression='String(ctg_cd) + "#$%" + String(app_cd) + "#$%" + String(app_cd) + "#$%" + String(win_id) + "#$%" + String(ctg_cd) + "#$%"'
This expression is then used in a modify statement to create the new compute key column:
ls_rc = ads_obj.Modify("create compute(band=detail x='0' y='0' " + &
"height='0' width='0' name=pfc_tvi_key " + ls_Exp + ")")
In earlier versions, this works, and when you do a getitemstring afterward you get a long concatenated value that PFC uses to uniquely identify treeview items.
Such as 'a/r#$%plcy#$%plcy#$%w_m_plcy_fncl_tran#$%a/r#$%'
However, in PB 12.6, only the first portion of the expression is processed. There is no error returned from the Modify function, and the column is created, but the expression is only evaluating one part of the expression. In this partiular case, it results in
'plcy'
I just noticed that this isn't the *first* item in the set of concatenated columns and string literals, which is interesting. In any case, when the computed key values are not correct, the whole method PFC is using to populate and run the treeview falls apart, and you get all children under each parent, and selections on the treeview object do not work properly because the key column values are not unique.
I can copy the expression value from a debugging session, and use that to create a computed column at design time, pasting the expression in, and naming it the same as the created column (pfv_tvi_key), and this then allows the treeview to work properly. However, this is a very cumbersome and problematic workaround. The application has a lot of treeviews, with a very large number of datawindows operating as all the different types of items on different levels of different trees. I don't think it's a practical workaround, and future maintenance would be very difficult.
bu the workaround still demonstrates it is not an issue with the syntax of the compute expression, just an issue with the way it is handled by PowerBuilder when a column is created at run time,vs. at design time.
Has anyone else encountered this issue? I would think there are a fair number of older apps still around that are using PFC treeviews.
My next step will be to install PB 12.6 build 4011 and cross my fingers. Other than that, perhaps try 12.5?

Updating the PFC layers has started to lead down a rabbit hole of hundreds and hundreds of errors.
Granted, many of these are probably rooted in a few ancestor issues.
But I'm not sure this will lead to a solution.
The problem lies in using a modify statement to create a computed column at run time containing an expression with multiple concatenated values.
If I look at the pfc_u_tv.of_createkey function from the newer PFC version, I see the same code there:
ls_rc = ads_obj.Modify("create compute(band=detail x='0' y='0' " + &
"height='0' width='0' name=pfc_tvi_key " + ls_Exp + ")")
And the same code above it which creates the expression used in the modify.
So after doing all the patching for the new PFC version, I somehow suspect I'll still be facing the same datastore.modify problem.
Not to say that isn't a good thing to do, just not sure it addresses the root of the problem.

Run-time app initialization?
