HTBasic hanging while doing a GPIB command, Called from TestStand

I have functions in HTBasic called from TestStand for doing GPIB communications for different test sets. When i run the main sequence, the sequence hangs in a HTBasic step. The step is different every time. Does anybody know about this problem?

Hi,
I have some questions.
Does the HTBasic programs run by themselves?. Or does it only hang when executed in TestStand?.
What GPIB driver and interface are you using?. What GPIB operations are you performing?. Is there any error message shown?.
The main idea is to figure out if the error is caused by the GPIB operation or by TestStand.
Include any information you may consider important.

Verizon - Iphone 6 plus - phone app getting hanged while doing 3 way conference call

I am using VOLTE in IPHONE 6 Plus with IOS 8.1 and when I am trying to do 3 way conference: I called person A and then I add person B, then I see the following issues:
I press Merge calls and calls are merged but still merge calls & Swap icon is enabled.
When person A/B hangsup, the phone app is hanged and call is ended but it still shows that phone is ending.
If I end the call, still the phone app is hanged and it shows it is ending.
I cannot do any dialing in the phone when phone app is hanged and literally, I have to restart the phone only.
Any other person cannot call me and it goes to voicemail.
All the above issues were happening in IOS 8 and IOS 8.0.2 also. I did reset network settings too but it did not help.
Can someone give an idea for any solution.

mehulkothari,
Thank you so much for those details. I want to make sure that you are able to use the feature without any issues. One thing that we might want to check out is that all the people that are a part of the 3 way calling is in the Verizon 4G LTE network. This could cause some issues if they are not. Have you been able to power the device off all the way and also remove the sim card for a good 10-15 seconds? http://vz.to/1EdNNMe Please keep us posted.

Passing telnet session between LabVIEW calls from TestStand

From TestStand I am calling VI's from telnet.llb.
In one TestStand step am opening a telnet session to an IP address and collecting the telnet connection (U32). In the next TestStand step I pass the telnet connection to a telnet write VI but get this error.
"Dequeue Element in Acquire Semaphore.vi:1->Telnet Write.vi:1->Telnet Write.vi.ProxyCaller"
The telnet open, write, read, and close work great if I pass the telnet session number within the same VI. But I need to keep the session open between calls from TestStand because one huge VI is not feasible.
thank you

2811(NM-8AM) does not answers incoming call from PC

Dear friends,
We are planning to setup an out of band management connectivity, in our test setup we have a Cisco 2811 ISR (with IOS 12.4(9)T5 ) with NM-8AM (Analog modem module) installed.
Test Setup:
1. One Analog line (PSTN) connected to PC via built-in modem
2. Second Analog line (PSTN) connected to Cisco 2811 (NM-8AM) terminated on the analog modem module
3. Both the analog lines are working fine.
Test Scenario:
1. The router should accept the incoming call from PC. And from the PC we should be able to telnet into the router via dial up connectivity (Out of band)
Test procedure:
1. The Cisco 2811 router is configured as follows:
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
hostname Dial-Up-CPE
boot-start-marker
boot-end-marker
logging buffered 16384 debugging

flowcontrol hardware
line vty 0 4
password cisco
scheduler allocate 20000 1000
2. With the above configuration, the router is not able to answer the incoming call from the PC.
3. And from the PC we are able to dial to a PSTN number at the router side, PC gives a proper dial tone and once the number is dialed, the call is landed on the other side (router end) and it rings continuously. But, the router does not answer this incoming. The analog line at the router end is terminated on async interface 1/0.
As I am new to dialup connectivity with NM-8AM, Could some please suggest the proper configuration in our router configuration OR Are missing any commands?
Any links/references would be of great help.
Thank you
Pradeep

Hi,
I guess I'm having exactly the same setup. The integrated modem on the other end does pick up the call but soon disconnect after displaying "Waiting for carrier".
Any clue?
Thanks,

Can't close CVI panels in DLL-Detach when called from Teststand

Hello,
i've got a problem with Teststand calling a DLL produced with CVI.
1. I use to DLL Attach and Detach calls to load or discard the panels. The attach part works fine, but when the TS sequence ends and i try to unload the module, the "DiscardPanel" function returns a error -129 "operation can only be performed in the thread it was created".
If i call the same dll from a CVI executable, this doesn't happen.
2. Additionally, the first time i run the sequence file the panel doesn't correctly quit and return to Teststand, so the whole thing hangs.
Does anybody have an idea, what is going wrong?
See attached files:
ErrorOnDllDetach.seq --> Call DLL from TS
\bin\usePanelsDll_dbg.exe --> Call DLL
from CVI

NoUnloadOfDll.zip ‏326 KB

Maik -
After some more investigation, because of limitations in Microsoft's operating system, developers and CVI are limited in what they can do in DLLMain. Basically load and unload CVI panels in DLLMain just does not work well if the DLL is loaded and unloaded arbitrarily like it is in TestStand.
One option is to never unload the panels and let CVI and the OS clean up the panels when the process terminates. You can do this by adding an extra reference to your DLL using LoadModule. You would basically prevent TestStand from unloading the DLL, so any dialog would stay around for as long as you like.
The best way to have the dialog go away when TestStand is no longer using it is to associate your dial
og lifetime with the execution that is displaying it. You load the panel either when the first call is made into the DLL or by an explicit call to a "Display" function exported from the DLL. Then have the dialog monitor for when the execution is terminated or stopped. This works because TestStand does not attempt to unload the DLL until the execution that is using it completes.
I have attached an example DLL and sequence that does just this. It uses a default pool thread to display a panel and that thread waits for either an explicit call to a "Discard" function exported from the DLL or or if the execution stops.
Hope this helps...

Excel 2013 hangs while trying to open a file from network share

Hi,
I am having issue opening excel file from a network share. it happens randomly, the file opens and hangs abruptly. Nothing happens after that ( we can only move the cursor), if we click on the excel sheet we get a beep sound. after i kill the excel process
and open it again ,it works fine.
Where did the member use the Excel file? Local disk, SharePoint, File server, or network shared disk?
       Network shared file and sometime locally
Does the issue occur in the special file or every file?
      it happens randomly and the whole excel freezes. i have to kill the excel session.
Which Office version is the file created? Excel 2013 or early? If it is XLS format, please try to convert to XLSX to test.
   Network file server has office 2010 and the user is trying to open it in excel 2013
Does the file have some macros?
Yes, they have macros in some files
Does the issue occur recently? If it is, have you installed some programs or update before you encountered it?
       it happened before too.
Do you get some error message when Excel crashed?
Yeah. Attaching the error message from event viewer. We get file corrupt errors and below too.
Please suggest

How do I improve performance while doing pull, push and delete from Azure Storage Queue

Hi,
I am working on a distributed application with Azure Storage Queue for message queuing. queue will be used by multiple clients across the clock and thus it is expected that it would be heavily loaded most on the time in usage. business case is typical as in
it pulls message from queue, process the message then deletes the message from queue. this module also sends back a notification to user indicating process is complete. functions/modules work fine as in they meet the logical requirement. pretty typical queue
scenario.
Now, coming to the problem statement. since it is envisaged that the queue would be heavily loaded most of the time, I am pushing towards to speed up processing of the overall message lifetime. the faster I can clear messages, the better overall experience
it would be for everyone, system and users.
To improve on performance I did multiple cycles for performance profiling and then improving on the identified "HOT" path/function.
It all came down to a point where only the Azure Queue pull and delete are the only two most time consuming calls outside. I can further improve on pull, which i did by batch pulling 32 message at a time (which is the max message count i can pull from Azure
queue at once at the time of writing this question.), this returned me a favor as in by reducing processing time to a big margin. all good till this as well.
i am processing these messages in parallel so as to improve on overall performance.
pseudo code:
//AzureQueue Class is encapsulating calls to Azure Storage Queue.
//assume nothing fancy inside, vanila calls to queue for pull/push/delete
var batchMessages = AzureQueue.Pull(32); Parallel.ForEach(batchMessages, bMessage =>
//DoSomething does some background processing;
try{DoSomething(bMessage);}
catch()
//Log exception
AzureQueue.Delete(bMessage);
With this change now, profiling results show that up-to 90% of time is only taken by the Azure Message delete calls. As it is good to delete message as soon as processing is done, i remove it just after "DoSomething" is finished.
what i need now is suggestions on how to further improve performance of this function when 90% of the time is being eaten up by the Azure Queue Delete call itself? is there a better faster way to perform delete/bulk delete etc?
with the implementation mentioned here, i get speed of close to 25 messages/sec. Right now Azure queue delete calls are choking application performance. so is there any hope to push it further.
Does it also makes difference in performance which queue delete call am making? as of now queue has overloaded method for deleting message, one which except message object and another which accepts message identifier and pop receipt. i am using the later
one here with message identifier nad pop receipt to delete message from queue.
Let me know if you need any additional information or any clarification in question.
Inputs/suggestions are welcome.
Many thanks.

The first thing that came to mind was to use a parallel delete at the same time you run the work in DoSomething. If DoSomething fails, add the message back into the queue. This won't work for every application, and work that was in the queue
near the head could be pushed back to the tail, so you'd have to think about how that may effect your workload.
Or, make a threadpool queued delete after the work was successful. Fire and forget. However, if you're loading the processing at 25/sec, and 90% of time sits on the delete, you'd quickly accumulate delete calls for the threadpool until you'd
never catch up. At 70-80% duty cycle this may work, but the closer you get to always being busy could make this dangerous.
I wonder if calling the delete REST API yourself may offer any improvements. If you find the delete sets up a TCP connection each time, this may be all you need. Try to keep the connection open, or see if the REST API can delete more at a time
than the SDK API can.
Or, if you have the funds, just have more VM instances doing the work in parallel, so the first machine handles 25/sec, the second at 25/sec also - and you just live with the slow delete. If that's still not good enough, add more instances.

Caller ID does not work when calling from Jabber

We have the following results when doing calls within the company:
Desk Phone A (4567-X-Smith): 7801234567
Desk Phone B (4568-Y-Miller): 7801234568
Main Company Line: 7801230000
All desk phones have the following type of configuration:
Under the phone -> Line[1] -> Line1 on Device <MAC>
Display (Internal Caller ID): 4567-X-Smith
ASCII Display (Internal Caller ID): Our Company Name
Line Text Label: 780-123-4567
ASCII Line Text Label: 780-123-4567
External Phone Number Mask: 7801230000
Desk Phone A calls Desk Phone B
- caller ID shows up properly on Desk Phone B as 4567-X-Smith
User at Desk Phone A makes the call through the Jabber client to Desk Phone B
- caller ID shows up as 7801230000
This last situation is the problem since we want all internal calls whether they're form the desk phone or Jabber to show the proper caller ID. However, we want the generic main company line (7801230000) to show up to anybody outside the company. What is set incorrectly? Why does Jabber take over the line but not keep the same caller ID settings? Does jabber work as if it's doing an external call?
Thanks in advance,
Kris

Interesting... I just 4-digit dialed 8182 (typed in the Search field at the top of the jabber window) and my proper caller ID showed up...
Next I tried 10 digit dial 7804988182 through jabber and it showed 7804988100 (our external calling mask). I also just noiced that it very briefly flashes 97804988182 so that seems to indicate it's trying to dial through the PSTN...
Oddly enough, if I 10 digit dial through my desk phone, it shows the proper caller ID.

How to display non modal dialog box in a Dll call from TestStand implemented in visual c

Dear Jason F.

Hello
I did the same way you told me
the non modal dialog appeared and
system hangs and

""SeqEdit.exe-Application Error
The instruction at �0x047fc5b0� referenced memory at �0x047fc5b0�. The memory could not be �read� ""
please solve my problem
and thanks for yours early response

Hi Mkehret,
Does your dialog have ActiveX controls on it? If your DLL dialog uses ActiveX controls and is not programmed in a certain manner it can hang because of a conflict in the threading model used by the TestStand Engine that is calling into your DLL and the model that is required by the MFC ActiveX Container. If you are using ActiveX controls in your dialog, you need to make special considerations for the threading model MFC dialogs that use ActiveX controls need in order to work properly. The example under \Examples\MFCActiveXContainerDlg illustrates how to appropriately handle this situation as well as explaining why it is necessary.
Note: The above example displays the dialog as modal, but this is irrelevant to the problem I am describing.
Again for information on properly creating a dialog class object and displaying it as non-modal refer to the information on MSDN that I referred you to in this post:
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000E98A0000&USEARCHCONTEXT_CATEGORY_0=_8_&USEARCHCONTEXT_CATEGORY_S=0&UCATEGORY_0=_8_&UCATEGORY_S=0
If your dialog does not use ActiveX controls or after trying the programming method illustrated in the "MFCActiveXContainerDlg" example TestStand still hangs when calling your DLL, try calling your DLL from another environment just to make sure whether the DLL works at all. If the DLL works properly when called by another environment (e.g. VB, VC++, LabVIEW, or CVI), please submit a MINIMAL and REPRODUCEABLE example source project for your DLL for us to look at (please exclude all unnecessary code not required to reproduce the specific problem of displaying the dialog, and include all files necessary to build your dll with any
specific instructions needed to do so).

Error Code -2147467259 when custom FrontEnd Callback is called from Teststand.

Hello,
For the project I am working on, the standard LoginLogout sequence has to be overriden from a custom one. The sequence i implemented does the following: A connection to a database, located on a virtual machine at my pc, is initially opened, the user name and password are given by the user through a message popup and the information is compared to the database entries. If the username and password are valid, a new TestStand user with the corresponding user information and priviliges is created and set as current user. If not, the procedure is repeated five times and if it ends unsuccessfully, the user account is blocked.
The implemented sequence works just fine when I run it independently in TestStand, while I'm logged in as administrator using the standard TestStand Front End callback. When I added it in the LoginLogout sequence in the FrontEndCallbacks.seq in C:\Users\Public\Documents\National Instruments\TestStand 2010 SP1\Components\Callbacks\FrontEnd in order for this to be called instead of the standard one, I received the following errors:
1. Error HRESULT E_FAIL has been returned from a call to a COM component. Error Code= -2147467259
This error appears immediately after I open the sequence editor. (see also attached images
2. LABVIEW: (Hex 0x80004005) Unspecified error.
This error appears when I run the customized user interface in LabVIEW that calls the FrontEnd callback in the TtestStand public folder. After the error message appears my custom login dialog pops up and after the user logs in (the procedure works as expected) and then presses OK to the error message, the vi stops. It cannot execute further.
I suspect that there is a problem when connecting to the database but I cannot understand what it is or why this is happening since the sequence runs without problems in Testand.
Could someone help?
Thank you very much!

I am sorry for the omission. As seen during a highlighted execution of the GUI, the error appears after the call of IApplicationMgr.Start (see attached image).

While loop stuck in LabVIEW when VI called by TestStand only

LabVIEW 8.5, TestStand 4.0, Windows XP-SP3
The issue I’m facing is a different behavior of a LabVIEW VI whether it is called independently (in the LabVIEW environment: normal behavior) or from TestStand (unexpected behavior).
In the same VI, I've wired in parallel, so they can execute in parallel:
a call through “System Exec”, to a program which prompts for a user's answer. The case I’m concerned is when the answer will never come...
a while loop, managing a timeout which finally kills the program above when it waits infinitely for a user's answer
Just to be more precise for those who’d try reproducing the issue (but you might just have a look at the enclosed VI): in my case the program is the command line WinSCP.com. WinSCP prompts when it wants you to accept the host’s private key which is not in its cache. Don’t be afraid if you’re not used to WinSCP, the concern here is LabVIEW + TestStand.
What happens when we’re stuck in the “System Exec”:
under LabVIEW: it works fine, as expected; while stuck in the “System Exec”, the while loop executes in parallel
when the same VI is called in a TestStand sequence step (ActiveX automation server to the LVdevelopment system), it does not run the while loop (we're stuck in both System Exec and inside the loop). The only way to release everything is to manually kill the program called by the System Exec through Windows Task Manager.
For information, all tasks: TestStand (SeqEdit), LabVIEW and program (WinSCP) show 0% CPU and their memory usage is stable.
Have you an explanation for this unexpected / different behavior of the VI, only because it is called from TestStand?
Enclosed is the VI.
If you actually want running it, you might have WinSCP installed and a valid session to an accessible host (adapt path to WinSCP and session name), and do not put the host key in the cache!
Note: you won't see the same issue with other programs or commands called by System Exec (e.g. netsh, ftp...) even if they await a user's prompt.
Thanks for your help!
Solved!

Industry error while doing replication of customer from R/3 to CRM

Hi,
We have production system already implemented and going for roll out for another company both R/3 & CRM.
We have generated conditional objects while doing roll out phase. From then we are getting this error.
Problem:
Customers are not getting replicated to CRM. And in SMW01 the error log says
"Industry 300 not defined for industry system SAPS
Validation error occurred: Module CRM_BUPA_MAIN_VAL, BDoc type BUPA_MAIN."
Since we are going for roll out we have done initial load of all conditional objects
like 'DNL_COND_A002' etc.
After running we did checked in R3AM1 - everything was DONE - in green colour.
But in SLG1 - Display log - there are several entries in Red colour.
Message text says -
"It is not possible to change client-independent Customizing objects
Diagnosis:
Change of client-independent Customizing objects is not permitted in the client in which the transfer of data for table T682 is executed.
System response:
As table T682 contains client-independent Customizing, data transfer is interrupted.
Procedure for System Administration
Provide users with the appropriate authorization to execute data transfer in a client in which changes to client-independent objects is permitted."
Now queues are pilled up with the industry error and don't know how to correct these errors.
Please help.

Hi pankaj,
Step 1:After completing Initial Download tranfer of data takes place from R/3 to CRM system in the form of Customers or employess.
Bulk data will be flown in the first step.
I f there are any errors ,we solve the errors and replicate them manually by using CRMM_BUPA_map.
Step2:There are few customers which are created daily in SAP SD or R/3 and these customers are transfered from R/3 to CRM .
So my question is Is this b'cos of Delta Download or Bcoz of some other Reason.
If so "Is there any specific name for this.

Hi
It would depend on the settings made by you in the depn. areas .
Step 1 : Execute the T code ORFA - Navigate to Depriciation - ordinary depn. - Assign accounts
Step 2 :You can navigate as follows - ORFA - Valuation - Depriciation areas - define dep. areas . ( Define depn. areas ) .
Here you need to check the field - POST TO GL ACCOUNT , if it is not ZERO '0' then the sytem would post the depn. and would require account determination for the same .
