Cloned VI aborts when caller VI closes

OK, I know this is a common problem... you want to create a VI that spawns a clone of some other VI, but when the caller's call chain execution completes, the clone(s) created automatically abort.
It seems like there must be a way around this.
Example of a use case: I want to create a LabVIEW Step in TestStand that launches a daemon or engine that will run continuously in the background.
Anyone out there who knows how this can be done? Seems like I may have done it before, but I can't seem to figure it out now. Some way of creating an independent holding location for the reference?

That is the garbage collection doing its job since it thinks you forgot about the background VIs. Don't you hate it when LV cleans-up behind you?
Have the spawned VI open a ref to itself when it starts so it can keep itself open.
Now if that does not do it, add the extra step of getting a ref to its FP.
I usually do both and don't remeber if it was the VI ref or the FP ref that keeps it alive.

Subvi flashing on screen when called

Hi All,
I have a subVI flashing up on my screen when called even though I have
all options unchecked on the subVI properties box (from the calling
VI). I have a sneaking suspicion it is something obvious. Any ideas?
Thanks,
Greg

Hi,
Have you checked the show "Front Panel When Called" and "Close Front Panel
When Loaded" check boxes.
Regards,
Wiebe.

Unexpected delay when dynamically called VI closes

LV10.0 / WXP
A VI is called dynamically by Run VI Method (Wait Until Done = FALSE, Auto Dispose Ref = TRUE).
Queues are used to exchange data with the main VI.
When this VI closes ("stop" message from the main VI), LabVIEW hangs for about 25 seconds (!) with one of the CPUs of the dual core machine at 100%.
Has anyone else encountered this strange behaviour ? Any ideas ?
Many thanks in advance
Solved!
Go to Solution.

Norbert B a écrit :
Can you give us a small picture of the way you are calling and releasing the subVIs?
As mentionned in my first message : Run VI Method (Wait Until Done = FALSE, Auto Dispose Ref = TRUE) is used to call the VIs.
Release : after reception of a "close" message (queue), the dynamic VIs terminate their execution
If called with Auto Dispose Ref = FALSE, the freeze appears when Close Reference is executed in the calling VI (after reception of a "I'm closing" message from the dynamic called VI).
If loading the VI takes only a short time but unloading takes long, it seems to me that those subVIs allocate many new handles/memory spaces during runtime. Is that the case?
As mentionned in a previous message : The memory usage changes from about 687 to 676 MB when the four
instances are closed. The number of handles decreases from about 272k to
61k.
This sounds like the whole application freezes for the time being. Is it a single loop architecture?
No. It is a rather big application with several VIs running independently and exchanging data through queues.
In addition: You call those subVIs dynamical with reentrant execution (at least some of them). So they should run in parallel.
Yes, they run in parallel.
Did you configure different preferred execution systems for your different subVIs?
Yes, I have tried several combinations and also changed the Priority. I also tried to replace the While Loop of the VI which communicates with the PLC by a Timed Loop in order to specify the processor. Unfortunately all my trials ended without any succes.
Did you check for reference leaks using the Execution Trace Toolkit?
Yes. There are none.
Norbert

Software error (outside VM) when calling JMF Player::close()

First off, I apologize for cross posting this here and in the "General Java Programming" forum. I did not know there was a forum specific for JMF, until someone mentioned it to me.
I have written the following test program:
import java.io.File;
import java.io.IOException;
import javax.media.Time;
import javax.media.Player;
import javax.media.Manager;
import javax.media.NoPlayerException;
class MyMP3Player {
public static void main(String [] args) {
try {
File mp3File = new File("test.mp3");
Player aPlayer = Manager.createPlayer(mp3File.toURL());
aPlayer.start(); // Starts asynchronous playback
Thread.sleep(10*1000); // Allow playback to continue for 10
aPlayer.stop(); // stops playback (well, it really PAUSES!!!)
aPlayer.deallocate();
aPlayer.close();
catch (IOException e) {e.printStackTrace();}
catch (NoPlayerException npe) {npe.printStackTrace();}
catch (InterruptedException ie) {ie.printStackTrace();}
The program runs fine for the first 2 times: I can hear the first 10 seconds of the test.mp3 file. Then, on the third run (and every other run after that), after it has played the file for the 10 seconds, the program gives me the error pasted below and exits. Does anyone know how to fix this? Am I doing something wrong in the program? Oh, and yes, I have tested it with other mp3 files and it still does the same thing.
BTW, I am running WinXP, and JMF 2.1.1e . Also, I have noticed that JMStudio does not have this problem, does JMStudio not call Player::close() ever?

Actually, I just ran another test. My previous fix does work 100%, but it is not necessary to call the Player::close() from within the AWT/SWING event dispatching thread, but it IS a requirement for you to have an AWT/SWING event dispatching thread running somewhere in the background, otherwise the darn thing crashes...
So, if you create some kind of GUI along with your app (thereby creating an AWT/SWING event dispatching thread), or just schedule some event using the SWING Timer class, the Player::close() can be called from any thread...

Is it possible to step into a CVI dll when called by TestStand?

As the question says: "Is it possible to step into a CVI dll when called by TestStand?"
I am sure Ray F. may have a few tricks up his sleeves... Hope you see this post, Ray!
I compiled a dll using CVI. The dll is called as a test by TestStand.
I do have an "exe" version of the code that I use for debug with a testbed, but the behaviour is not the same as testing the actual target while running TestStand. My goal is to get as close as possible to the real events.
Thanks,
JLV

Sorry about that,
There are two ways as I was saying:
1. You can configure the CVI adapter to Execute Steps in a External Instance of CVI (requires CVI 6.0 or greater).
Only go to Configure->Adapters and select the LabWindows CVI adapter and click on configure and select the corresponding option.
After that set a break point in the step that you want to debug.
An external instance of CVI will be launched where you can set break points and step into the code.
2. From CVI Specifying an external process:
In CVI go to Run Specify External Process and enter the seqEdit.exe as the program name (you have to browse to the location <TestStand>\Bin\SeqEdit.exe).
As the argument you enter the name of the sequence file you want to debug.
Now just select Run->Debug SeqEdit.Exe
The Sequence Edtior will be launched and you can set break point in your CVI code and step into it when the step is executed.
Check the Using LabWindows/CVI with TestStand reference manual for more information.
I hope it helps you to get started.
Regards.

Bug in Oracle JDBC Driver: NullPointerException when calling clearParameters

There is a bug in the latest version of the JDBC driver that throws a NPE when calling PreparedStatement.clearParameters(). I don't need a response to this, since I have a workaround (just catching and ignoring the exception), but it should probably be fixed. I speculate that the problem only occurs when you try to call clearParameters() more than once on the same PS, but I haven't confirmed it.
It is probably an easy fix. Following is the stack trace:

Take a look at the method that is causing the NullPointerException:
public void clearItem(int i)
if (!m_dynamic && m_vector == null && i < m_vector.size())
m_vector.removeElementAt(i);
if (m_items != null && i >= m_items.length)
return;
m_items[i] = null;
return;
A NullPointerException will be thrown whenever clearParameters() is called when no parameters have yet been bound.
The first IF statement should read:
if (!m_dynamic && m_vector != null && i < m_vector.size())
A simple workaround would be to make sure that your parameter list is never empty before calling clearParameters(). Is there a patch for this anywhere?

Connection remains opened even after calling conn.close

i have a need to copy records from one table in a database (say db1) to another table in another database(say db2). I open connection to both databases, and get a Recordset (say rs1) by executing a query that contains all rows that i have to insert in the database db2. Next i get an empty recordset(rs2) on the table in the database db2 (with locktype batchoptimistic, clientside cursor). i loop on rs1 and for each row in rs1 i insert a row in rs2 and copy the fields. after all rows are done, i delete the rows from db2 that will be affected and do an updatebatch on rs2. then i close the recordsets and the connections
everything works fine except that the connection with the db2 is not getting closed, neither is it throwing any exception. when i comment the updateBatch code the connection closes normally.
can anyone please help me out, where am i going wrong.
thanks
Vijay Sharma

Hi,
There is one more thing that I want to add to the above question. After calling conn.close() I checked the status of the connection and it was not 'OPEN' but when I checked session information through DBA studio it was showing one connection. I enabled trace of Oracle provider for OLE DB. Trace showed that two sessions were opened but only one session was closed.
Thanks,
Vijay

FaceTime freezes when same room has no problems. The picture is high resolution. There are no freezes when calling my daughter's iPad but the picture is lower resolution. Can I troubleshoot this?

FaceTime freezes when I call my son's iPad. Calling his iPhone in the same room has no problems. The picture is high resolution. There are no freezes when calling my daughter's iPad but the picture is lower resolution. Can I troubleshoot this?

Thanks Mario, but I tried everything there before posting my question. I may not have been clear in my question since I accidently recorded the whole question as the title and tried to edit. In brief: I have no trouble connecting with my daughter's iPad or my son's iPhone. However, his iPad is sending much higher resolution pictures and we disconnect after about a minute. Oddly, he can hear and see me while my screen first freezes, then goes black and gives me a message of "reconnecting" until it quits trying and shows the buttons to end or redial. The picture quality difference is what is leading me to believe it is bandwidth related. However, I get anywhere from 5 to 10 MB download speeds; usually closer to 10. Last summer, I had 4 granddaughters on their iPads, a grandson on his gaming device and me on cell phone or pc, all using the bandwidth at once with no complaints. If there is a way to lower his outgoing resolution, I think that would help.

Core Dump when calling DriverManager.getConnection

I'm very confused and hope someone can help me out with this.
I'm trying to make a connection to a MS SQL Server 7 and am getting a core dump when getConnection is called. No exception is thrown, just a core dump and locked session. If I run the class from it's main there is absolutly no problem, but when I do a new on the class and call it's member to establish the connection: core dump. The environment is the same in both cases. The calling class did does use a mySql connection, but I tried closing it and setting it to null with the same problem. I'm not sure if the getConnection is stepping on a socket or what it's trying to violate in memory causing the dump. This is running on a SCO Openserver 5.0.5 box (green threads). Why it runs stand-alone and not when called from another class has got me tangled... Thread problem? I've tried several SQL drivers, they all do the same thing.
Anyway, here's a snippet from the java class:
try
{Class.forName(myForName);
// core dump, next line
Connection myConn = DriverManager.getConnection(myUrl, myUser, myPass);
// never get's here
Statement myStmt = myConn.createStatement();
catch (Exception e) // modified for this post
{system.out.println(e.toString());
Here's the dump printed to the monitor (2>&1)
SIGSEGV 11* segmentation violation

I have a similar problem with establishing a connection through JNI. Have you resolved your problem?
Here's mine.
In java, I have a class that provides an interface to a mysql database. The java programs that call this interface work fine.
When I try to call the java interface from C++ through JNI, I get the following output -- some debug statements sprinkled through also. I am assuming that the JVM is missing something at runtime that is there in my JRE. The classpaths match , etc. Exception handling in java and in JNI code are not providing any more detail.. Thanks for comments!!

Simsession short dump when calling BAPI

Hello,
I have created a macro in Demand Planning that calls BAPI_APO_AVAILABILITY_CHECK.
When running this is SE37 or SE38, everything works fine. But when calling this from //SDP94 I got a shortdump, because the BAPI wanted to create a simsession, but there was already an existing simsession.
Do you think, this is an error in the BAPI, or do i have to handle this in the calling FM?
Would this be the right approach:
FM "Z_TEST"
CALL FUNCTION //RRP_SIMSESSION_GET         -
Save SIMSESSION from DP
CALL FUNCTION //RRP_SIMSESSION_LEAVE     -
Clear Simsession
CALL FUNCTION //BAPI_APO_AVAILABILITY_CHECK
CALL FUNCTION //RRP_SIMSESSION_SET         -
Set old SIMSESSION back
I do not understand the purpose of the SIMSESSION, so I rely on your comments and help.
Thanks for any feedback,
BR,
Dominik

Hi Domink
Simsessions are simulation sessions or work areas for transactional live cache data. You must create a simsession in order to retrieve and work with data from live cache. When finished you should close the simsession however most times the end of a LUW will delete the simsession. If data created/changed in a simsession needs to be saved an explicit LC commit may be required but in most cases that is taken care of within SAP code. In fact, the leave simsession fm will determine that data in the simsession has changed and ask if you want to save.
I am not sure if you can get around the simsession creation problem in the ATP BAPI. If you had control over the code such as in a Zfunction module you could either not create the simsession or force a merge of simsessions. Do not code the leave simsession because that will delete (rollback) or force the save of the changed data from your planning book before you entered the macro - in addition when you return to your planning book from the macro there will not be a simsession for you to save or change data.
Why are you running ATP from within a DP planning book? Are you looking for what stock is available to update another KF? Do you need to run through the entire ATP process to retrieve an available qty or can you use a simpler function module to retrieve the stock? Another option is to read the planning book in a stand alone program, do the ATP check and whatever logic is necessary before writing back to the planning book.
Hope this helps

I just wanted to provide an update to this. I did find a work-around for this, but I cannot explain it. The post I added to a related thread on 23 Sept. 2009, Trying to change the data source for a Crystal Report. (thread 1472257), explains a work-around I found for that problem. It seemed to resolve this one simultaneously.


I don't know why it works. If anyone has a comment or some insight, it is welcome. Thank you in advance.

LogOnException thrown when calling ExportToStream

Hi there, 
 
I am having real problems when calling the ExportToStream method on the ReportDocument class. 
 
I am trying to load a CrystalReport that is held in a Database field, apply parameters to that report (the values for the parameters) are also held in another database table, and then export the report (complete with the parameterised values) back to another record in the DB. 
 
All goes swimmingly until I try to call ExportToStream to finally place the report (with params) back in DB. When I get to this call I get a LogOnException thrown (Message: "Logon failed.
Details: 08004:[Sybase][ODBC Driver][SQL Anywhere]Parse error: Invalid or missing keyword near 'DATABASE'
Error in File C:\DOCUME1\BARRY1.ROB\LOCALS~1\Temp\tmp16C {8CF0E4A7-E74C-41DC-BF7E-5871D40432E9}.rpt:
Unable to connect: incorrect log on parameters."). 
 
The code causing the excpetion is the call to ExportToStream below: 
public void ProcessQueuedReports(string connectionString, ProcessQueueMode processMode, string providerName) 
{ 
 
List<ReportQueueDetails> queuedReportList = ReportQueueDetails.GetAllQueuedByPriority(connectionString); 
 
 if (queuedReportList.Count > 0) 
{ 
 int numberToProcess = ReturnNumberToProcess(processMode,
 queuedReportList.Count); 
 for (int count = 0; count < numberToProcess; count++) 
 { 
 SetQueueItemAsProcessing(queuedReportList[count]); 
 if (reportReader.LoadReport(connectionString,
 queuedReportList[count].ReportDetailsRef,
 queuedReportList[count].ReportQueueDetailsRef, providerName)) 
 { 
 ExportFormatType outputFormat =
 ReturnExportFormatType(queuedReportList[count].ReportFormatTypeCode); 
Stream reportStream = new MemoryStream(); 
 reportReader.Report.ReportOptions.EnableSaveDataWithReport = false; 
 reportStream = reportReader.Report.ExportToStream(outputFormat); 
 byte[] reportData = new byte[(int) reportStream.Length]; 
 int numBytesToRead = (int)reportStream.Length; 
 int numBytesRead = 0; 
 reportStream.Position = 0; 
 while (numBytesToRead > 0) 
 { 
 int n = reportStream.Read(reportData, numBytesRead, numBytesToRead); 
 if (n == 0) 
 break; 
 numBytesRead += n; 
 numBytesToRead -= n; 
 } 
 queuedReportList[count].ReportOutput = reportData; 
 queuedReportList[count].Update(IyssDateTime.CurrentDatabaseDateTime); 
 SetQueueItemAsSuccess(queuedReportList[count]); 
 } 
 else 
 { 
 SetQueueItemAsFailed(queuedReportList[count]); 
 } 
 } 
 } 
} 
 
This is the LoadReport method called above: 
 
public bool LoadReport(string connectionString, int reportDetailsRef, int reportQueueRef, string providerName) 
{ 
 bool LoadSuccess = false; 
 ReportDetails report = IyssReportDetails.GetByRef(reportDetailsRef,
 connectionString); 
 byte[] reportData = (byte[])report.ReportData; 
 int size = reportData.GetUpperBound(0); 
 string tempFilename = Path.GetTempFileName(); 
 if (tempFilename != "") 
 { 
 FileStream fs = new FileStream(tempFilename, FileMode.OpenOrCreate,
 FileAccess.Write); 
 fs.Write(reportData, 0, size); 
 fs.Close(); 
 try 
 { 
 LoadSuccess = LoadReport(tempFilename, connectionString, providerName); 
 ProcessReportParameters(connectionString, reportQueueRef); 
 } 
 finally 
 { 
 //File.Delete(tempFilename); 
 } 
 } 
 return LoadSuccess; 
} 
 
The LoadReport method referenced in the above method is as follows: 
 
public bool LoadReport(string fileName, string connectionString, string providerName) 
{ 
 bool LoadSuccess = false; 
 _report = new ReportDocument(); 
 _report.Load(fileName); 
 LoadSuccess = _report.IsLoaded; 
 if (LoadSuccess) 
 { 
 if (_report.ParameterFields.Count > 0) 
 ProcessReportParametersBasedOnReportInfo(); 
 SetReportDataConnection(_report, connectionString, providerName); 
 } 
 return LoadSuccess; 
} 
 
And, what I guess is the crucial code, here is the SetReportDataConnection code: 
 
public void SetReportDataConnection(ReportDocument report, string connectionString, string providerName) 
{ 
 string Locn; 
 if ((report != null) && (report.DataSourceConnections.Count > 0)) 
 { 
 for (int count = 0; count < report.DataSourceConnections.Count; count++) 
 { 
 string dsnName = GetDSNName(connectionString, providerName); 
 ConnectionInfo connectionInfo = RetrieveConnectionInfoFromRegistry(dsnName); 
 Tables tables = report.Database.Tables; 
 foreach(Table table in tables) 
 { 
 TableLogOnInfo tableLogonInfo = null; 
 tableLogonInfo = table.LogOnInfo; 
 tableLogonInfo.ConnectionInfo.ServerName = connectionInfo.ServerName; 
 tableLogonInfo.ConnectionInfo.DatabaseName = ""; 
 tableLogonInfo.ConnectionInfo.UserID = connectionInfo.UserID; 
 tableLogonInfo.ConnectionInfo.Password = connectionInfo.Password; 
 table.ApplyLogOnInfo(tableLogonInfo); 
 if (connectionInfo.UserID.ToUpper().CompareTo("DBA".ToUpper()) != 0) 
 { 
 Locn = table.Location; 
 if (!Locn.StartsWith("Proc(", StringComparison.OrdinalIgnoreCase)) 
 { 
 if ((!Locn.StartsWith("DBA", StringComparison.OrdinalIgnoreCase))
 && (!Locn.StartsWith("SYS", StringComparison.OrdinalIgnoreCase))) 
 table.Location = "DBA." + Locn; 
 } 
 } 
 } 
 report.DataSourceConnections[count].SetConnection
 (connectionInfo.ServerName, "", connectionInfo.UserID,
 connectionInfo.Password); 
 } 
 } 
 if (!report.IsSubreport) 
 { 
 if (report.Subreports.Count > 0) 
 { 
 for (int count = 0; count < report.Subreports.Count; count++) 
 { 
 SetReportDataConnection(report.Subreports[count], connectionString,
 providerName); 
 } 
 } 
 } 
 } 
If anyone has any idea why the ExportToStream call in the first causes the Exception, or can point me in the direction of where I am going wrong in setting the report's data connection, I'd really appreciate it. 
 
Thanks In Advance 
 
 p.s. - tried to format this as best I could, apologies if it is not all that clear
 
 Development language is C# Using Visual Studio .NET 2008
 Reports written in version 11 of Crystal Report.
Edited by: silentbazz on Jun 3, 2009 6:07 PM

You mention:
"Development language is C# Using Visual Studio .NET 2008
Reports written in version 11 of Crystal Report."
But what version is the CR runtime used in your .NET 2008 app? (e.g.; what is the version of the CR assemblies referenced in your app - say crystalDecisions.Crystalreports.engine.dll?)
Next, assuming you are using a version of CR supported with .NET 2008, I suppose the 1st question to ask is; is it export to stream, or is it incorrect db logon parameters that is causing the issue.
I'd recommend starting with the basics:
Simple app; viewer, load the report, let it do all the prompting. Does that work?
If yes, add the logon code to the above app, let it prompt for any parameter it needs. Does that work?
If yes, add the parameter code, does that work?
If all of the above works, try to export the report from the above app using the viewer export button. Does that work?
If that works, we're finally at the stage where we can point our finger at export to stream(?).
