Reference to all ApplicationModule

Is there a way to get a reference to all ApplicationModules of the system used (by name maybe), so I can call rollback or commit on each one.
I need away different than the following way:
return (ApplicationModule)JSFUtils.resolveExpression("#{data."+name+".dataProvider}");
Thanks

You only need to rollback the rootApplicationModules because all nested application modules share the same transaction.
If you have access to one application module you can try looking for the other modules via getSession().getAllApplicationModuleDefNames().

How can I get a reference to all controls on a front panel of one type )for example of the type Text Ring?

I'd like to set the strings[] property of all the Text Ring controls on a front panel at once without creating a property node for every text ring. How can i do that?

This is likely more complicated than making property nodes for each
ring, but you can do it. Make a subVI that takes in a panel reference,
reads the array of control references, loops through them looking for
rings, and modifying the Strings[] property on each ring.
The part of this that will probably be the least obvious, when you
have an array of control references there are two ways to find out
if an element is a ring. You can read the classID and compare it
to the cla
ssID of a true ring control. An alternative is to cast
the control reference to a ring control using a Cast to more specific
node and wire the error out to a case structure. The error case is
where the objects that aren't rings will go. The success case case
where you will have a valid ring refnum that you can use to modify
the strings.

Get Specific References for all Controls

Using slightly modified code from here, I am generating an array of all control references on my main front panel which is then passed through to a number of subVIs. Although this functionality does work, it would be preferable to get specific references to the controls (for example, Boolean RefNum instead of Control RefNum).
Getting these specific references seems possible using To More Specific Class and Class Specifier constants. However, data storage becomes an issue because I can no longer use arrays (as they are a different data type). I am not sure if there is another way to pass this data on. I have experimented casting the RefNums to Variants, but to get the data from the variant, I have to know what RefNum type I am expecting which sort of defeats the purpose of doing this in the first place.
A secondary problem is keeping the names of the references. The Control RefNums do not have names associated with them nor do I know how to assign names to them. I've again tried using variants and using the OpenG Set Data Name function, but this crashes LabVIEW without any indication of why.
I've attached a version of my code that tries assign names using OpenG Set Data Name and build a variant array. To run it, simple add the VI as a subVI to a VI that has some boolean controls on the Front Panel. Apologies for the rough state of the code - I'm still in the process of figuring out how to make it work so things are a bit messy.
Solved!

Get Specific Control Refs.vi ‏28 KB

I don't know if you'll get much better. There is really no way I know of to have some fully flexible way of building named clusters of references based on any given front panel set you feed to it.
I tend to do things the manual way (as there are also a bunch of references to front panel elements I wouldn't need). I would do all the bundling work in a subVI.
I'm attaching a zip file that contains the key VI's (unless I missed something) on the first project where I really tried to abstract out the reference building. The files are LV9.
On my main VI, I have the subVI called Build UI References early in the VI during an initialization phase. I pass the reference to the main VI into that subVI that builds all the references. I worked it as a master cluster that contains elements that are arrays of references of related controls. It uses another subVI called Get References and Label Names that I created to help find controls. I still need to use More Specific Class to get the property references, but I don that only once at the beginning. I then pass that cluster wire out and to anywhere in my VI that would need access to the references for front panel elements.
I use arrays of strings to supply the names I need to build and bundle the references. This lets me ignore controls I don't care about. The disadvantages to my system is that if I change the name of any control, I need to update the name within this subVI. And if I want to add any controls, not only do I need to add the label names for the searching functions, I also need to update my typedef cluster (and you definitely want this to be a typedef) to add a spot to store the new reference.
I hope this gives you some ideas. It worked for me and I will likely use the scheme on another project (or even rewrite past projects using this scheme.) If there are any ideas for improvements, I'd be happy to hear them.

Can I get the reference to all objects in JVM Heap?

Hello,
Thanx in advance for reading (and replying) to this problem.
I need to find an object whose reference I dont have.
I feel the best place to search for is the JVM heap.
If I get that JVM heap, and am able to get all the objects created, I can locate the particular object that I am looking for.
Is there a way to od this????
Any suggestions ????
Vikas

JVMTI will mostly help you in this case. But i recomend you to review you application design, because such services are unsafe and rather tricky.

Does mxctrllib provide a call which returns a reference to all the logical names in MAX?

I'm looking for a call that returns all the MAX logical names on a system. I would populate a drop-down box with those names to allow the user to select a name at program run-time. Currently I hard code a particular logical name as a string and init the session. This is not flexible. Thanks ...

The NiMxCtrl.dll which is the server for the mxctrllib objects is meant for National Instruments internal product use only. There is no documentation for developing 3rd party apps that utilize its functionality.
I'm not sure if you are talking about the IVI logical names listed in MAX or not, but if you want to know where you can get a list of these, they are in the ivi.ini file found in your C:\VXIpnp\Win95\niivi directory. Just parse this file to read all of your IVI logical names and setup parameters.

Does DeleteGlobalRef(saved reference) delete all global references?

Hello,
I have a question regarding global references, if you assign two global references to the same object by....
static jbobject savedReference, sameSavedReference Object,
savedReference = env->newGlobalRef(obj);
sameSavedReference = env->newGlobalRef(obj);
then you call
env->DeleteGlobalRef(savedReference);
savedReference = null;
sameSavedReference = null;
When does the java object with the pointer sameSavedReference get garbage collected?
Does the env->newGlobalReference hold a reference onto the same object, even if we called deleteGlobal with savedReference?
Do you need to call also?
env->DeleteGlobalRef(sameSavedReference);
I know that if you try to access sameSavedReference after
env->DeleteGlobalRef(savedReference);
savedReference = null;
sameSavedReference is no longer valid, however that could just mean that the global reference got deleted, and you need to resign sameSavedReference to another global reference.
Whew this is confusing :) Any help would be appreciated!
Tom

I'm taking a guess :-) but I think if the references are different then they should be deleted. If the references are different, even if to the same object, I would think the deleteGlobalRef tells the JVM to remove that reference. I hope someone wiser will confirm :-)

InDesign CS5 for Mac crashes on opening file. Have replaced References and all other suggestions.

I am having a problem with InDesign CS5 crashing when I try to open a file that formerly opened just fine. Even restored versions from Time Machine or that I had a backup saved on an external hard drive will not open. I recently had to reconstruct a 90 page magazine for the same reason. I heard that Extensis Suitcase might be causing the problem so I disabled the plug-in, but still can't get the file open. The file in question is full of tables and would be a nightmare to redo. I am running Snow Leopard. It will open briefly and tell me that fonts are missing, then crash.
This is the first part of the crash report:

I have already disabled the Extensis plug-in and am activating the fonts

I got rid of the Mindsteam grammar plug-in also and sent a tersely

expect it to work. I don't have time for this aggravation! I truly
appreciate the help I've gotten here. This has certainly discouraged me
from using any third-party plug-ins. I was ready to go back to Quark

LNK2001: undefined reference to all the export functions from .def

hi
i am getting link error(s) when i call function(s) from dll, and wondering the cause.
i use the std calling convention and the function(s) from my
dll.h is/are coded as:
#define DLLROUTINE void __stdcall
typedef int MVSDD;
DLLROUTINE mvstestmsdn_DLL(const double gamma, const double omega,...);
In dll.def, i define:
EXPORTS
mvstestmsdn_DLL @12
Eventually from my dll.c, when i call
mvstestmsdn_DLL();
i got error LNK2001:unresolved external symbol mvstestmsdn_DLL
Thanks in advance for any help on this.

I have added as suggested from dll.h
#define DllExport _declspec(dllexport)
typedef int MVSDD;
extern _declspec(dllexport) mvstestmsdn_DLL(const double gamma, const double omega,...);
As a result:
on a positive side i've now got only 10 LNK2019 errors such as
error LNK2019: unresolved external symbol _mvstestmsdn_DLL referenced in function _main
compared to 93 errors LNK2001 from my previous post
Over roughly hundreds of functions, it's a nice improvement.

How can I get a reference to ApplicationModule in a servlet

I know that I can easily get the reference to my ApplicationModule in any JSP using the tags but I need to use a servlet instead of a JSP.
Would you please let me know how I can a reference to my ApplicationModule in my Servlet? Every function that I am trying to use has been depricated.
I appreciate any help.

The following code will instantiate a module for you...
public static ApplicationModule getGenericApplicationModule(String sAppModule, String sConnection)
throws Exception {
if (am != null)
return am;
sName = sAppModule;
sConn = sConnection;
Hashtable env = new Hashtable(2);
env.put(Context.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
Context ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(sName);
am = home.create();
am.getTransaction().connect(sConn);
return am;
Problem in a servlet environment is that this is not pooled so you want to use the pool manager like this...
public static EDMSMgrImpl getPooledApplicationModule(String sPoolName) throws BaseBc4jException
ApplicationPool aPool = getApplicationPool(sPoolName);
try
return (EDMSMgrImpl)aPool.checkout();
catch (Exception e)
String message = "Exception checking out pool: "+sPoolName+" : "+e.getMessage();
LogBroker.getInstance().severe(_instance,message ,e);
throw new BaseBc4jException(message, e);
protected static ApplicationPool getApplicationPool(String sPoolName) throws BaseBc4jException
ApplicationPool aPool = PoolMgr.getInstance().getPool(sPoolName);
if (aPool == null)
try
createPools();
aPool = PoolMgr.getInstance().getPool(sPoolName);
catch(IOException ioe)
String message = "IOException thrown in EDMSAppModuleHelper.createPools" + ioe.getMessage();
LogBroker.getInstance().severe(_instance,message, ioe);
throw new BaseBc4jException(message, ioe);
if (aPool == null)
String message = "got a null result when getting pool: "+sPoolName;
BaseBc4jException e = new BaseBc4jException(message);
LogBroker.getInstance().severe(_instance, message, e);
throw e;
return aPool;
Where a pool is created like this...
sPoolName = poolElem.getAttribute(POOL_NAME_ATTRIBUTE);
sAppModule = poolElem.getAttribute(APP_MODULE_ATTRIBUTE);
sConnection = poolElem.getAttribute(CONNECTION_ATTRIBUTE);
stateFull = poolElem.getAttribute(STATEFULL_ATTRIBUTE);
sClass = getPoolClass(poolElem);
if(PoolMgr.getInstance().getPool(sPoolName) == null) {
Hashtable info = new Hashtable();
info.put(JboContext.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
info.put(JboContext.DEPLOY_PLATFORM, "LOCAL");
info.put("IsStateLessRuntime", stateFull);
PoolMgr.getInstance().createPool(sPoolName, sClass, sAppModule , sConnection, info);

How to find references of a Property in the class through code? similar to 'Find All References' in Visual Studio Environment.

Hello,
I am trying to find a code to find all the references of the property defined in a class which is very similar to 'Find All References' function available in Visual Studio environment. But I want to have it in code during run time. How to do it?
e.g
=>Property 1
private int _Salary;
public int Salary()
get{return _Salary;}
set{_Salary = value;}
=> Property 2
private int _Bonus;
public int Bonus()
get{return Salary * 2;}
Like in the above example I have two properties Salary & Bonus. Bonus is calculated from salary. As soon as I set a value to Salary, value of Bonus gets updated.
Similarly I want to get reference of all other properties or methods in the class or program which are affected when value of Salary is changed through code.
Conclusion - I want to have a method or function, so that whenever I set a value to some property in a class, I want to have a list of all the other properties(List<Property>) or methods which are affected and in which the changed property is referenced.
Please help me to achieve this.
Siddharth.Shinde

This is not something possible, as requested, even with reflection.
I can't find the reason for having that kind of implementation at runtime.. your compiled assembly is not going to change once it's compiled.
The way references are listed from within visual studio is probably using metadata gathered from the background compiler. When you write code, the compiler run pre-compilation tests, this is the same feature that will display error in your code before you
compile, or complete your intelisense for types that aren't even compiled in the assembly.
So, the only way for you to analyze this kind of thing would be to use something like ILDASM to disasemble your compiled libraries and gather metadata from the resulting MSIL. That would not work if you are using code obfuscation by the way.

ApplicationModule reference to writeXML from dynamic view object

I need to create a class or a bean that my JSP pages will instantiate and based on the JSP request type, this class creates a ViewObject dynamically. After generating the view, I would like to use the ViewObject.writeXML function and pass an XSL file reference into it and send the generated XML to the requesting JSP file.
1. I would NOT want to use the tags to create the application module.
2. I use the oracle.jbo.html.jsp.JSPApplicationRegistry.registerApplicationFromPropertyFile to register the application module.
3. At this point, I need to get a reference to my ApplicationModule to call the createViewObjectFromQueryStmt.
How and where can I get a reference to the application module at this point.
I would really appreciate your help, comments, and suggestions.
Thank you

ISync not syncing all contacts to Moto Razr V3i

Hi,
I have a Motorola Razr V3i that I'd like to sync with my Mac address book. I'm running Leopard 10.5.1. I keep the Address Book as the reference for all my contacts. When I connect my Razr to the Mac, I want to replace all the contacts on the phone with the entries in the Address Book. I have set options in iSync to sync all contacts with phone numbers. I am facing two problems with this:
1) During the sync, the application tries to replace data on my Mac with data from the phone. Is there an option that I can set by which the information on the Mac is never overwritten by the information from the phone? I want information to go one way all time - from my Mac to the phone.
2) After the sync, I discovered that not all the contacts had been imported. A few random contacts are not transferred from the Mac to the phone. I thought that this might have something to do with the fact that the phone used to be synced to my earlier install of Tiger. So I did a "master clear" and a "master reset" on the phone. But even after doing that, some of the contacts (different ones this time) were not synced. And due to the problem described in #1, iSync tried to replace all my existing contacts on the Mac with blank information on the phone.
What's the point of iSync if I have to check whether all contacts have been imported, and manually enter the ones left out. I checked for a software update on the phone, but there was none available.
I'd be happy to provide additional information to get this problem fixed.
Thanks,
Saurabh

I am having the same problem with Leopard 10.5.1 Isync and my razor V3 from Cingular. In addition the contacts in my address book are duplicated after syncing with my phone. Basically after using Isync my address book gets doubled and cluttered with names and no phone numbers, the data gets completly screwed up. Whats going on?

In-Place Element Structures, References and Pointers, Compiler Optimization, and General Stupidity

[The title of this forum is "Labview Ideas". Although this is NOT a direct suggestion for a change or addition to Labview, it seems appropriate to me to post it in this forum.]
In-Place Element Structures, References and Pointers, Compiler Optimization, and General Stupidity
I'd like to see NI actually start a round-table discussion about VI references, Data Value references, local variables, compiler optimizations, etc. I'm a C programmer; I'm used to pointers. They are simple, functional, and well defined. If you know the data type of an object and have a pointer to it, you have the object. I am used to compilers that optimize without the user having to go to weird lengths to arrange it.
The 'reference' you get when you right click and "Create Reference" on a control or indicator seems to be merely a shorthand read/write version of the Value property that can't be wired into a flow-of-control (like the error wire) and so causes synchronization issues and race conditions. I try not to use local variables.
I use references a lot like C pointers; I pass items to SubVIs using references. But the use of references (as compared to C pointers) is really limited, and the implementation is insconsistent, not factorial in capabilites, and buggy. For instance, why can you pass an array by reference and NOT be able to determine the size of the array EXCEPT by dereferencing it and using the "Size Array" VI? I can even get references for all array elements; but I don't know how many there are...! Since arrays are represented internally in Labview as handles, and consist of basically a C-style pointer to the data, and array sizing information, why is the array handle opaque? Why doesn't the reference include operators to look at the referenced handle without instantiating a copy of the array? Why isn't there a "Size Array From Reference" VI in the library that doesn't instantiate a copy of the array locally, but just looks at the array handle?
Data Value references seem to have been invented solely for the "In-Place Element Structure". Having to write the code to obtain the Data Value Reference before using the In-Place Element Structure simply points out how different a Labview reference is from a C pointer. The Labview help page for Data Value References simply says "Creates a reference to data that you can use to transfer and access the data in a serialized way.". I've had programmers ask me if this means that the data must be accessed sequentially (serially)...!!! What exactly does that mean? For those of use who can read between the lines, it means that Labview obtains a semaphore protecting the data references so that only one thread can modify it at a time. Is that the only reason for Data Value References? To provide something that implements the semaphore???
The In-Place Element Structure talks about minimizing copying of data and compiler optimization. Those kind of optimizations are built in to the compiler in virtually every other language... with no special 'construct' needing to be placed around the code to identify that it can be performed without a local copy. Are you telling me that the Labview compiler is so stupid that it can't identify certain code threads as needing to be single-threaded when optimizing? That the USER has to wrap the code in semaphores before the compiler can figure out it should optimize??? That the compiler cannot implement single threading of parts of the user's code to improve execution efficiency?
Instead of depending on the user base to send in suggestions one-at-a-time it would be nice if NI would actually host discussions aimed at coming up with a coherent and comprehensive way to handle pointers/references/optimization etc. One of the reasons Labview is so scattered is because individual ideas are evaluated and included without any group discussion about the total environment. How about a MODERATED group, available by invitation only (based on NI interactions with users in person, via support, and on the web) to try and get discussions about Labview evolution going?
Based solely on the number of Labview bugs I've encountered and reported, I'd guess this has never been done, with the user community, or within NI itself.....

Here are some articles that can help provide some insights into LabVIEW programming and the LabVIEW compiler. They are both interesting and recommended reading for all intermediate-to-advanced LabVIEW programmers.
NI LabVIEW Compiler: Under the Hood
VI Memory Usage
The second article is a little out-of-date, as it doesn't discuss some of the newer technologies available such as the In-Place Element Structure you were referring to. However, many of the general concepts still apply. Some general notes from your post:
1. I think part of your confusion is that you are trying to use control references and local variables like you would use variables in a C program. This is not a good analogy. Control references are references to user interface controls, and should almost always be used to control the behavior and appearance of those controls, not to store or transmit data like a pointer. LabVIEW is a dataflow language. Data is intended to be stored or transmitted through wires in most cases, not in references. It is admittedly difficult to make this transition for some text-based programmers. Programming efficiently in LabVIEW sometimes requires a different mindset.
2. The LabVIEW compiler, while by no means perfect, is a complicated, feature-rich set of machinery that includes a large and growing set of optimizations. Many of these are described in the first link I posted. This includes optimizations you'd find in many programming environments, such as dead code elimination, inlining, and constant folding. One optimization in particular is called inplaceness, which is where LabVIEW determines when buffers can be reused. Contrary to your statement, the In-Place Element Structure is not always required for this optimization to take place. There are many circumstances (dating back years before the IPE structure) where LabVIEW can determine inplaceness and reuse buffers. The IPE structure simply helps users enforce inplaceness in some situations where it's not clear enough on the diagram for the LabVIEW compiler to make that determination.
The more you learn about programming in LabVIEW, the more you realize that inplaceness itself is the closest analogy to pointers in C, not control references or data references or other such things. Those features have their place, but core, fundamental LabVIEW programming does not require them.

How can I get command values from a VI executed by reference ? NEWBIE

Hi,
I'm running a sub-vi in a "Secondary Front Face" (excuse for the
translation if not correct, I'm working on a French version). In order
to run this VI, I pass a reference. All is working fine but I don't
know how can I get the values entered by the user in this VI ?
Actually I run a main VI wich contains a "Secondary Front Face" (this
SFF is contained in a tabbed pane). In my diagramm, I pass a reference
to another VI (by the name of the file *.vi). If my user enter a word
in a text field, I would like to be able to get it in my main app.
Thanks for your help.

Hello,
You might take a look at the following tutorial for more information about calling a VI by reference. It's got some great visuals and examples.
Tutorial: Calling a VI by Reference
You might also consider just calling the secondary VI as a simple subVI, if you can spare the memory space when loading the main application, as this is the easiest way to input and output VI values.
I hope this helps! Please let me know if I can be of any further assistance.
