Get StepType reference
Hello,
I want to change a steptype with the Teststand API in LabView by using the method ChangeStepType. The input parameter is a stepTypePtr as StepType. But how can I acquire a StepType reference as a parameter.
Thanks for help!!!
Regards
Matthias
Hi Ray,
thanks for your answer.
Yes, it would worked with your first example, but I want get the reference by the way described in the Teststand API Reference Help. There ist written for the method ChangeStepType:
ChangeStepType Method
Syntax
Step.ChangeStepType ( stepTypePtr)
Purpose
Changes a step's step type.
Remarks
Returns an error if the step does not allow changing its step type. To avoid this error, only call ChangeStepType if CanChangeStepType returns True.
To acquire a step type to pass as a parameter, call Engine.GetTypeDefinition and pass the name of the desired step type, then query the returned PropertyObject for its StepType interface.
Parameters
stepTypePtr As StepType
[In] The step type to which you want to convert the step.
My problem is to convert the reference, which get by the call Engine.GetTypeDefinition into a StepType reference.
Do you have an idea?
Thanks for help!!!
Kind regards
Matthias

Excel Get ActiveX References.vi and closing references -- grrr
I'm new to ActiveX stuff, but eager to learn!
The "grrr" in my Subject line is a reference to how I feel about LabVIEW's documentation from time to time. I'm a dinosaur who came from text-based programming, and did a fair amount of C coding, so sometimes with LabVIEW I'm left with this awful feeling in the pit of my stomach like, "Good grief! How much memory must LabVIEW be hogging up in the background when I use this vi?" or "What happens to those variables (wires) in that subVI when it completes but doesn't close? What are their statuses when I come back in the next time?" or "What if I put a lot of elements into that array the first time and then started from element zero the second time and just put in a few? What has happened with the memroy that was allocated when there were a lot of elements?"
Today I'm stewing about this "Excel Get ActiveX References.vi," and what happens to the "ActiveX references" it generates each time I call the subVI in which "Excel Get ActiveX References.vi" lives. I think that at least one of the "ActiveX references" it generates when I call it is of the type Excel._Application. Then there appears to be an Excel._Workbook, and others. You see, I've used "Excel Easy Report.vi" to put some data into an Excel spreadsheet, and I want to tell Excel to do a "Save" on the open spreadsheet. I think ActiveX is the (a) right way to do that, so I'm wading into the ActiveX fray... But this "Excel Get ActiveX References.vi" says in its help file, "Do not close ActiveX references opened with the Excel Get ActiveX References VI. References must remain open until the report is closed. Otherwise the error 3001 will occur." Well, these Excel workbooks that get created by my VI could well stay open until after my LabVIEW VI terminates!
So (finally), here are some of my quesitons:
1) When I go through my subVI once, pointing to one workbook, I'll get one set of references "created" or "opened" or whatever you call it when ActiveX references spring into existance. Now, when I exit the subVI, is it going to automatically try to "close" those ActiveX references? I don't suppose so, since subVI's stay in memory until the calling VI closes.
2) Now, I come back into my subVI a second time. New workbook gets created, so I get new references. Ok, fine. Uh oh! What happened to those old references? I suppose that if I didn't somehow save them off, I've probably lost the ability to get them back (maybe I'm wrong, but I don't need them back), but is LabVIEW going to "close" those old references (from previous times through the subVI) because I can't get to them anymore? Won't that cause the dreaded error 3001? If LabVIEW is not going to "close" them, what in tarnation happens to them (the old C programmer in me creeping back out)?? Now it's some oddball, orphaned reference, floating out there, hogging memory, waiting to make something crash intermittently and be a debugging nightmare?
3) Now, here's the real scary one. I think I might dodge the "error 3001" bullet in questions 1) and 2), but now let's say the user closes my LabVIEW application while Excel is still open. All those workbooks are still open. Presumably, all those ActiveX references I was not supposed to close are still open. I really hope that LabVIEW is decent enough to close/erase/delete/blow-away (whatever the right word is) all those ActiveX references which were opened/created by "Excel Get ActiveX References.vi" when my program terminates. But, oh no! Won't the error 3001 come along then? I suppose I can just dump it in the shutdown error handling.
Well, thanks for reading my novel. I don't know what can be done with LabVIEW documentation to make it more satisfying to folks like me, but perhaps someone can weigh in on all my ActiveX questions here.
Thank you in advance,
Steve Brady
Solved!
Go to Solution.You need to close EVERY ActiveX reference you open. If you don't you'll end up with some Excel processes running even after LabVIEW exits. You can see them in Task Manager.
I, personally, don't like the LabVIEW Report Generation Tool Kit for working with Excel. I don't think it's flexible enough. I have a growing library of VIs that I've written that open, manipulate, and close Excel. Some references I pass from VI to VI and some I close right after I use them. It all depends on what I'm doing. If I want to enter read or write data from/to a certain range I'll get the range reference, read or write the data, then close it right away because I have no use for it any more. On the other hand, when I open Excel or a Workbook I keep the reference until I'm done, which could be later in the program.
1) When I go through my subVI once, pointing to one workbook, I'll get one set of references "created" or "opened" or whatever you call it when ActiveX references spring into existence. Now, when I exit the subVI, is it going to automatically try to "close" those ActiveX references? I don't suppose so, since subVI's stay in memory until the calling VI closes.
2) Now, I come back into my subVI a second time. New workbook gets created, so I get new references. Ok, fine. Uh oh! What happened to those old references? I suppose that if I didn't somehow save them off, I've probably lost the ability to get them back (maybe I'm wrong, but I don't need them back), but is LabVIEW going to "close" those old references (from previous times through the subVI) because I can't get to them anymore? Won't that cause the dreaded error 3001? If LabVIEW is not going to "close" them, what in tarnation happens to them (the old C programmer in me creeping back out)?? Now it's some oddball, orphaned reference, floating out there, hogging memory, waiting to make something crash intermittently and be a debugging nightmare?

But, oh no! Won't the error 3001 come along then? I suppose I can just dump it in the shutdown error handling.
1) No, LabVIEW will NOT close those references. You need to make sure that happens.
2) You can save the references in a functional global or use a class but if you're not going to save them close them as soon as you're done with them.
3) Your user should not be able to close your LabVIEW application without it going through the shutdown routine you've created for your program. The ABORT button should never be exposed to the user and you should capture and discard the panel close event so your program ALWAYS shuts down is an orderly fashion. If you don't you will have fragments of Excel hanging around in your operating system and will have to kill those processes using Task Manager. That should only be a problem during development, not once deployed.
I used to program in C and Assembly many moons ago. You should have seen my first LabVIEW code. I go back and look at it just so I can see how far I've come in the last 12 years. I feel your pain.

Not able to get the reference fot the new column added thru personalization
Hi,
I have added a new column in an advanced table of Message Text Input. ID for this is xxTemp.
Now i have extended controller and in processrequest(), i am trying to get the reference for this column as below:
OAAdvancedTableBean oaadvancedtablebean1 = (OAAdvancedTableBean)webBean.findIndexedChildRecursive("ASNPrdtLstTb");
OAMessageTextInputBean oamessagetextinputbean = (OAMessageTextInputBean)webBean.findIndexedChildRecursive("xxTemp");
But oamessagetextinputbean is returning null value.
Can someone tell me why this is not able to get the reference for the newly added column.
This is very urgent. please post me ur ideas.Hi Shiv,
I have used as u said. Its throwing this exception:

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 KBI 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.

How to get a reference to a Project Library?
Hello DSC 8 users,
In my project I have couple project libraries ( *.lvlib) defined, containing only shared variables. I want to logg those variables to Citadel, but I need to programmatically set datalogging properties for each library, like Database Computer, Database Name and path etc.
My problem is that I can not get the reference to a particular library, because ther is no VI inside. Is there any way to get the reference to a library based on Shared Variable name that is inside the Library?
I tried different approaches, the closest that I came is to store a VI inside the Library, get the reference to this VI and from tis reference I can get to Library property that I need.
But in case there is no VI inside, I can't do it. I'm sure there is a solution to this. Can somebody please help?
Thank you,
ROMPHi,
i might be overlooking something here, but i can only seem to open a vi refenece and not a "library" reference. when i use the "open VI reference.vi" from the programming->application controll menu it throws an error at me.
currently i have worked round this by using a member of the lib to then get its "library" property and do what i want from there. However this isnt the best way for me as i want to be able to start with just a .lvlib file path and then document information about this library.
Any help on how to open a ref to a .lvlib dirrectly would be fantastic.
Chris

How can we get the reference of XML element on frame as soon as frame is created in Document?
Hi,
When ever we copy any text/table cells from any frame, and paste it directly on page, A new Frame is created and the pasted text is placed inside that frame.
Now to capture this frame creation, We have two possible solutions:
1) Attach Observer on Document 'kDocBoss' on IID_IHIERARCHY_DOCUMENT and it will notify on frame creation in update function.
2) Notification event on new story creation.
Now, I need to perform some changes in the newly created table, for example:
a) Need to delete XML tags from newly created frame
b) Need to perform action on table cells if any in the created frame.
But the problem is, when the event comes, I can access basic properties of frame like it's name, type etc, but it does not give me the
XML element on frame or tables in frame until the event is com pleat.
I know it's quite a specif requirement, but I guess many of you might have faced these kind of challenges, while processing the event.
Does any one has any idea how I can get the reference of XML element on frame as soon as it is created?Hi Kapoor,
please give also others a chance, and excuse that I get up late on vacation ;-)
Anyway, I'd keep the story creation responder to recognize the copy, then combine it with an observer on the backing xml story to catch the associated XML element which is created there. Something like below:
UIDRef xmlStoryRef = Utils<IXMLUtils>()->GetBackingStore(doc);
InterfacePtr<ISubject> subject ( xmlStoryRef,IID_ISUBJECT );
subject->AttachObserver(observer,IID_IIDXMLELEMENT,observer->GetAttachIID()); -
How can I get a reference to the Local interface of a EJB 3 session?
Hi,
How can I get a reference to the Local interface of a EJB 3 session?
My session implements both the local and remote interfaces, so in my client, when I look up the remote interface using the following code, I did get a reference
processor = (IItemProcessorRemote)initialContext.lookup(IItemProcessorRemote.class.getName());but if I also look up the local interface in th eclient using this:
processorLocal =(IItemProcessor)initialContext.lookup(IItemProcessor.class.getName());I got errors like the following, do you know why? Thanks a lot!

Integer conversion = (Integer)conversionComponent.getValue();
Integer quantityInBags = (Integer)object;
//get labels from the two inputDate component.
String conversionLabel = conversionComponent.getLabel();
String quantityInBagsLabel = ((RichInputText)uIComponent).getLabel();
Integer remainder = (quantityInBags % conversion);
//throw error if valiation fails
if (remainder > 0) {
throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,
"The " + quantityInBagsLabel + " should be in multiples of" + conversion +".",
null));

How can i get the reference to Controls from VI-reference
Hello,
i have a VI with ~5 controls on it.
And with the Object "Current VIs path" and "Open VI reference" i can create a reference to the current VI.
How can i create now a reference to the controls? (Starting with VI-reference?
Of course i know how to create directly a reference from a control.
My idea wasm that there areperhaps properties like:
- Number of controls
- Name of control
- Type of control (string, bool. number...)
Is this somewhere there and i just dont find it?
Thanks for your helpOnce you have the VI Refnum, it's a two-step process. Wire the VI Refnum into a property node and get a reference to the Front Panel. Output the Front Panel reference into another property node and select the property Controls[ ], which outputs an array of references for all the controls on the front panel.

How to get File Reference of a properties file from EJB
Hi,
I am using Sun App server 7 with Oracle 9i. I am keeping all my SQL statements in a properties file from which I am loading it while making a database operation from Stateless beans. My problem is I am not able to get the reference of the properties file. Here is the code through which I am getting the SQL statements loaded to a cache.
String sqlFileName = "SQL.properties";
sqlCache.load(new FileInputStream(sqlFileName));
From the cache I am sending the SQL statement depending on the key value. But the problem is I have to keep the SQL.properties file on the App Server config directory of the instance where the server.xml file resides. Otherwise it is not able to find the properties file. But I don't want to put the properties file on the config directory of the server instance. Please help how to get the properties file from the packakge. My file is residing inside a package com.company.sql . Botht the properties file and the class accessing the file are residing in the same package. Please help how to get the reference of the file with out putting the file in the config directory.
Thanks
Amit PatnaikJust wanted to warn you of the hazards if you read a file from EJB
So please make sure that these hazards will not affect your application. However the solution suggested to use getResourceStream() concurs with ejbSpec
This snippet is from suns blueprint on ejb
Why can't EJBs read and write files and directories in the filesystem? And why can't they access file descriptors?
Enterprise beans aren't allowed to access files primarily because files are not transactional resources. Allowing EJBs to access files or directories in the filesystem, or to use file descriptors, would compromise component distributability, and would be a security hazard.
Another reason is deployability. The EJB container can choose to place an enterprise bean in any JVM, on any machine in a cluster. Yet the contents of a filesystem are not part of a deployment, and are therefore outside of the EJB container's control. File systems, directories, files, and especially file descriptors tend to be machine-local resources. If an enterprise bean running in a JVM on a particular machine is using or holding an open file descriptor to a file in the filesystem, that enterprise bean cannot easily be moved from one JVM or machine to another, without losing its reference to the file.
Furthermore, giving EJBs access to the filesystem is a security hazard, since the enterprise bean could potentially read and broadcast the contents of sensitive files, or even upload and overwrite the JVM runtime binary for malicious purposes.
Files are not an appropriate mechanism for storing business data for use by components, because they tend to be unstructured, are not under the control of the server environment, and typically don't provide distributed transactional access or fine-grained locking. Business data is better managed using a persistence interface such as JDBC, whose implementations usually provide these benefits. Read-only data can, however, be stored in files in a deployment JAR, and accessed with the getResource() or getResourceAsStream() methods of java.lang.Class.
Hope this info helps! -
How to get the reference of the component JSF by the faces context
I have :
<h:commandLink id="toto" action="#{controller.test}" >
I want to get the reference of this commandLink component in function test of "controller ", for instance , to get the "id" attribute of it, so how to do it? by facescontext??????
Thanks a lot.hi again:
to precise my question, i know that attribute "actionListener " of the component can let the controller.test know the reference of the component ,but if i want to know when the getters are called for example <h:outputText value="#{controller.myValue}"> it calles the controller.getMyValue() , so in the getMyValue, how to know which component calls him?
Thanks a lot... -
Get Control Reference From Connector Pane
I am trying to get a reference to a control associated with a specific index on the connector pane. I see that there is a method to assign a control to a terminal but not get control from a specific terminal. I know I can list all controls on the connector pane, but this doesn't tell me specifically where they are.
Edit: I see there are private methods for getting and setting properties which may have this info, but because these are undocumented and they are properties of a VI which is binary, I can't reverse engineer.

Solved!
Go to Solution.GregFreeman wrote:
The disconnect I had was that the array of controls that the connector pane property node will return has null refnums for unwired terminals, but there are still references for every terminal on the pane.
For learning about the terminals on an object, a good tactic is to drop the object on a diagram and select Visible Items > Terminals:
If you see completely enclosed terminal rects (like in the subVI terminals), then reading the "Terminals[]" property of the object will return all of them, even the null data type ones. So for the subVI, you can see that there are 12 distinct terminal rects, so that's how many terminals the object has. But on the built-in function, there are only 6 enclosed terminal rects. So reading the "Terminals[]" property on the subVI will return 12 items, and reading it on the function will return 6.

Good find on the example VI...
I wrote it (along with about 400 other VIs in the examples folder), so it was pretty easy to find.

Get Row reference in advanced table to set the value of custom column
Hi,
I have a requirement to add a new column PHP Amount in Manage Charge page which is a entry page where all the charges are entered for a PO. This region is based on Advanced table.
As per requirement, Newly created column should populate the value of the existing column (Amount) or vice verse i.e. value entered in amount column should be set to PHP Amount column for a particular row. and the value entered in PHP amount should be stored in the custom table.
I have added the column via personalization and setting the view attribute in extended controller as this column is not the part of the database table on which the VO is based upon. Also added a PPR event in process request function in controller. And getting the reference of the row in processForm Request's PPR event and invoking the method defined in my custom AM for getting and setting the columns values . Here i can't extend the root AM as the Page have LOV columns so i have created my custom AM and adding it dynamically in controller.
Here is the complete code
Controller Code
public void processRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processRequest(oapagecontext, oawebbean);
OAApplicationModule rootAm = oapagecontext.getApplicationModule(oawebbean);
OAApplicationModule nam = (OAApplicationModule)rootAm.findApplicationModule("XXIPCShipmentAMEx");
if (nam == null)
nam = (OAApplicationModule)rootAm.createApplicationModule("XXIPCShipmentAMEx", "xxipc.oracle.apps.inl.workbench.server.XXIPCShipmentAMEx");
OAAdvancedTableBean tableBean =(OAAdvancedTableBean)oawebbean.findIndexedChildRecursive("ChargeLinesAdvTable");
OAMessageTextInputBean phpAmt =(OAMessageTextInputBean)tableBean.findIndexedChildRecursive("XXIPC_PHP_AMOUNT");
OAViewObject ChargeLinesVO1 = (OAViewObject)rootAm.findViewObject("ChargeLinesVO1");
phpAmt.setViewUsageName("ChargeLinesVO1");
if (ChargeLinesVO1 != null)
try
String l_att= ChargeLinesVO1.findAttributeDef("PHPAmt").toString();
catch(Exception exception)
ChargeLinesVO1.addDynamicAttribute("PHPAmt"); //Adding ViewAttribute to VO
ChargeLinesVO1.reset();
phpAmt.setViewAttributeName("PHPAmt");
FirePartialAction FireActionA = new oracle.cabo.ui.action.FirePartialAction();
FireActionA.setEvent("PPR");
FireActionA.setUnvalidated(false);
phpAmt.setPrimaryClientAction(FireActionA);
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processFormRequest(oapagecontext, oawebbean);
OAApplicationModule rootAm = oapagecontext.getApplicationModule(oawebbean);
OAApplicationModule nam = (OAApplicationModule)rootAm.findApplicationModule("XXIPCShipmentAMEx");
OAAdvancedTableBean tableBean =(OAAdvancedTableBean)oawebbean.findIndexedChildRecursive("ChargeLinesAdvTable");
OAMessageTextInputBean Amt =(OAMessageTextInputBean)tableBean.findIndexedChildRecursive("Amount");
OAViewObject ChargeLinesVO1 = (OAViewObject)rootAm.findViewObject("ChargeLinesVO1");
String rowRef = oapagecontext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
Serializable[] param ={rowRef};
// IF PPR event bind with PHPAmount column is triggered
if("PPR".equals(oapagecontext.getParameter("event")))
nam.invokeMethod("PHPAmtPPRAction",param);
// IF changeChargeAmt event(Standard Event ) bind with Amount column is triggered
if("changeChargeAmt".equals(oapagecontext.getParameter("event")))
nam.invokeMethod("changeChargeAmtPPRAction",param);
Custom AM Code
public void PHPAmtPPRAction(String rowRef)
OARow row = null;
if (rowRef != null )
row=(OARow)findRowByRef(rowRef);
if(row != null)
Number phpAmt =(Number)row.getAttribute("PHPAmt");
if(phpAmt != null)
row.setAttribute("ChargeAmt", phpAmt);
public void changeChargeAmtPPRAction(String rowRef)
OARow row = null;
if (rowRef != null )
row=(OARow)findRowByRef(rowRef);
if(row != null)
Number chargeAmt =(Number)row.getAttribute("ChargeAmt");
if(chargeAmt != null)
row.setAttribute("PHPAmt", chargeAmt );
I m not able to set the PHP Amount column value entered in Amount column. But i am able to set the Amount column value to PHP amount column.
I m not getting the Row Reference in case PPR event triggered in PHP Amount column . It is giving Null reference in case of PHP Amount.
I don't know what i m missing ..Can anyone help me here..
Thanks in advance
Renubut using second way you will not be able to save those record in database, to save in database you have to override setter method also
Code will be like this -
public String getBillRemarks() {
return getSuppNmTrans(); // This is first Column Value
// return (String) getAttributeInternal(BILLREMARKS); }
public void setBillRemarks(String value) {
//Setting First Column Value in Second
setAttributeInternal(BILLREMARKS, getSuppNmTrans());
But i suggest you to use valueChangeListener on first field to set value in second one

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); -
Basic problem (annoying, if not disasterous - but common - at least for me):
When you are trying to sktick two different VIs together and you copy the block diagram of one to the other, it sticks all the controls in the middle of nowhere. THen you have to spend about 10 mins dragging the controls screen by screen from one end of the diagram to the other - sometimes over 15 screens. Surely there has to be a better way?
** Incidentally you might think that labview would have these sort of settings in the 'properties' of the control on the right click menu - but no joy.
I guess the obvious thing is that you can write a VI which will get a reference for a particular control and then say set it's position (x,y) to zero. Only thing is that generally there will be a selection of controls, and often they will be organised nicely - after getting them to zero you don't want to have to reorganise them again. I tried grouping the controls, but then the problem is - how do you get a reference to a group of controls. If you move one of them it doesn't keep the spatial arrangement. At this point i have got lost - and easily spent more time than it is worth fixing this problem.
Any thoughts?
Solved!
Go to Solution.If I understand you correctly, when you copy the block diagram from the second VI to the first, the controls of the second VI end up in far left field on the front panel of the first, correct? I think these added controls will maintain their relative locations among themselves so you should be able to find them all as a group out in left field. Then it's simply a matter of how to get them to enmasse join the rest of the controls on the front panel. There are a couple of easy ways to do this. There is a button on the toolbar at the top of the front panel window that allows you to reorder/group/ungroup front panel objects. You can select all controls/indicators out in left field and "group" them together. (As an alternative, you can also drop them all onto a tab control which will act as container for them). Then you select this group and with it selected scroll back over to the existing front panel and find and ALSO select (hold down shift key) a control/indicator from the existing group too. Then with BOTH the existing control selected and the new group (or tab control with the new group) selected you use the ALIGN buttons to quickly bring a corner of the new group into alignment with the old control. At that point you can ungroup the new stuff and move it where it needs to be.
