Hello,
There are any number of possible causes to this problem. Which version of Test Executive are you using? Have you upgraded your Test Executive recently? The latest version is 5.1.1. If you have changed anything about Test Executive on your computer recently, I recommend you perform a mass compile of all your VI libraries, as having different versions of the VIs on your system could often result in the "Call to Step XYZ Failed" errors. Also, are you using any DAQ or Analysis VIs in your steps? We have seen problems where the use of DAQ or Analysis VIs in the sequence can cause intermittent "Call to Step...Failed" errors. There are some KnowledgeBase entries on our website that discuss this problem. Are you using the Test Executive in the VI environment, or
as an executable? Again, there are some problems with using Test Executive as an executable that result in these errors, and there are also KnowledgeBase entries that discuss these problems.
If you have a pared-down application that demonstrates the problem, feel free to send me your VIs and your .seq file and I will try to reproduce the problem.
Alternatively, I would suggest you visit www.ni.com/teststand to learn about TestStand, our state-of-the-art Test Sequencing software that completely outperforms Test Executive. It is very easy to use and much more powerful, and we have a top-notch support team available dedicated exclusively to supporting TestStand. As you are probably aware, we are no longer developing Test Executive, and instead are concentrating our efforts on making TestStand the penultimate solution for all our customers' test sequencing needs.
I appreciate your patience on this issue. Please let me know if I can offer further assistance.
Have a pleasant weeken

When running labview's test executive I recieve runtime error: Call to step "PRE-RUN" failed. Could someone explain this error?

I have a set of vi's that work when run under labview. However, when calling these vi's from labview's test executive I recieve runtime error: Call to step "PRE-RUN" failed. in Assign Connector Pane.vi->Call Test.vi->Execute Pre-Run.vi->Test Executive. Could someone explain this error to me? (or ideally tell me how to fix it?) Thanks.

Flex 4.5.1 Setting VideoPlayer source to null when it is already null results in a runtime error

I moved my project from Flex 4.1 to Flex 4.5.1 and I noticed that setting VideoPlayer source to null when it is already null results in a runtime error. The same thing applies to the case where you specified as a source url some invalid location (no video found there) and then you try to set the source to null.
Here is the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at spark.components::VideoDisplay/cleanUpSource()[E:\dev\4.5.1\frameworks\projects\spark\src \spark\components\VideoDisplay.as:1956]
    at spark.components::VideoDisplay/setUpSource()[E:\dev\4.5.1\frameworks\projects\spark\src\s park\components\VideoDisplay.as:1609]
    at spark.components::VideoDisplay/set source()[E:\dev\4.5.1\frameworks\projects\spark\src\spark\components\VideoDisplay.as:1073 ]
    at spark.components::VideoPlayer/set source()[E:\dev\4.5.1\frameworks\projects\spark\src\spark\components\VideoPlayer.as:1362]
The problem is that in the VideoDisplay cleanUpSource function, in some of the cases there properties on the videoObject are modified like this:
videoPlayer.displayObject.visible = true;
without checking if displayObject is null which is done in the rest of the videoDisplay functions.
So when it reaches this line: videoPlayer.displayObject.visible = true; it results in a runtime error.
Is this supposed to work this way now ? I didn't have this problem on Flex 4.1. Not sure if it is a bug, but if it is please report it, I don't have the time right now to be checking in on this.
I fixed it by checking if the source is set, of course... (that won't help me in cases where I provide a wrong or missing video url by mistake.. so it is important to be fixed!)

Hi
I found the same error displaying video on flex !
in my simple code, i have :
videoInfoDataVideo.source = videoName;
the full error is :

Repeated blue screen crash when running labview 8.2 on Dell optiplex GX620

Hi, I have recently experienced a series of 'blue screen' crashes on a Dell Optiplex GX620 while running Labview 8.2. The dell is running Windows XP SP2 with an ATI Radeon X600 graphics card. Labview is interfacing with a NI DAQPad 6015 device. The computer is a dedicated Labview machine so there is no other third party software that has been installed that could be causing the problem. Also, the computer is one of three identical machines, the only one that has labview installed and the only one that is crashing. Upon rebooting after the first 'blue screen' crash an error report indicated that there was a problem with the ATI graphics driver and suggested updating the driver to the latest version. This was done. Upon rebooting after the second 'blue screen' crash an error report indicated that there was a problem with the RAM. Both of these crashes occurred while running a labview application. A further two incidents have occurred where the computer has restarted for no apparent reason while running a labview application. I was wondering if you were aware of any known issues/incompatibilities with my specific machine and labview 8.2, or if there could be any other known issues with labview that might be causing the crashes. It should also be noted that this is a new setup and these crashes have occurred in relatively short time frame. Thanks for your help!

Hi,
To have a better understanding of what is causing the blue screen crash and the Windows restart, we may need to retrieve the memory dump caused by the crash in Windows XP. Before we actually get into that, we may need to disable Automatic Reboot by Windows when it crashes. I have attached a link that describes how to disable computer reboot after a crash and I have also attached a link of how to retreive the memory dump. Let me know how it goes!
Why Does My Computer Automatically Reboot For No Reason?
How Can I Create a Kernel Memory Dump When Windows Crashes?
(Note that we want to select Complete memory dump, not Kernel Memory dump)

Run labview exe in other way than runtime engine?

Hi guys
This might be stupid question, but can I run labview's *.exe in other way than in the runtime engine? In these days in have done *exe and installer with runtime engine and give it to the end-user. It does not matter how tiny ur code is, user have to install 40 conponents and then restart computer... How annoying. Is there eny other way? Can i use other programming languages some how?
-AA-

If the runtime is only one out of 40 components, it should not make a big difference for you.
I always tell my users to download and install the runtime engine directly from NI. This needs to be done only once per PC and per runtime version, at which point you can distribute a small installer.
There is also an idea to simplify all this. Please support it.
(It is not reasonable to be able to build an executable with embedded runtime, that would make a LabVIEW 2009 executable 100+MB in size. (We had that back in LabVIEW 4.0, where each 20kb VI turned into a 3+MB executable, which was significant in the days of 1GB drives.)

While executing 'Z' BAPI Runtime error CALL_FUNCTION_NOT_FOUND has occurred

Dear Friends,
We Customized 'Z' BAPI but not transported to QA yet,
Is it possible to test with QA by fetch QA data by giving RFC target sys: (QA RFC Destination Name)
If I give RFC target sys: (QA RFC Destination), I am getting Runtime error CALL_FUNCTION_NOT_FOUND has occurred.
How to resole this....
What is method to check this customized BAPI with different server...../
It is working fine for Standard BAPI.
Regards

But you should be able to call it in the DEV system from QA. This will prove that the RFC part works.

Hi Victor,
I can't actually run your code above, because I'm missing the
XML file, etc. But the one thing that actually stands out to me is
that you are placing spry:region attributes on <table> and
<select> elements which aren't allowed.
The reason is that in IE, those elements have a read-only
innerHTML property, so they can't be used to insert new content.
The workaround is to wrap your <select> with a <span>
and your <table> with a <div> and then put the regions
on those elements.
See if that gets you going.

Error 10401 when running LabView

To start, I am using a PCI 6032E, SC-2345, SCC-SG04, and load cell as my means of DAQ. I have configured a VI for this both in traditional and DAQmx using the example on this site. I can also run a test in MAX and if I push on the load cell, the reading changes. However, when I try to run the strain.vi LabView program found on this site, I get an error 10401. I tried closing the programs and opening them again, but I still get the error. I even have tried restarting the computer, but I still receive the error. Any suggestions? Thanks.

After looking at the program I think I might know why you were receiving the 10401 error with the program. By default, the program doesn't give a channel to acquire from. The array of channels is empty (grayed out) initially and you will get the 10401 error until to enter a channel number or select a virtual channel.
With regards to the new problem, what OS do you have? If you have Windows 2000/XP, then here is what I would try. Go to the device manager in Windows and choose to uninstall the device. Then go into MAX and refresh (press F5) and make sure that the device doesn't appear in Traditional NI-DAQ folder (you may have to delete the device in NI-DAQmx). Close MAX. Then, go back to the device manager and choose Action>>Scan for hardw
are changes and let Windows reinstall the device. Now, go to MAX and test the device in Traditional NI-DAQ and NI-DAQmx.
Let me know if this doesn't get things working.
Regards,
Todd D.

PC slows down after a while when running labview application

I have a labview 6 application which is monitoring some data on a feildpoint module, after a while this application slows down and there is a lot of activity on the hard disk drive, also the cpu monitor says 100% activity.
Is it something to do with the PC or is it some other reason?
Thanks
Allan

Allan,
My first guess is "Who know's" without seing your VI and probing around; but, to get you started, run your VI and use Labview's tool "Profile VIs..." [Tools... Advanced...] and monitor memory and timing statistics. You may find a constantly increasing use of memory or a VI that consumes an unusual amound of processor time. Then you can troubleshoot from there.
Good luck with it, Doug

I ran the test 2 more times.
I forgot to have my scratch files go to a different drive.
I ran the test again the same as I ran the other 2 tests with all the files on ONE drive and here are the results.

Can you call an express VI interface when running LabVIEW code

I want to use an Express VI edit interface, in my program, so that I don't have to recreate the interface. Is it possible to call that VI to show its front panel in Express VI mode

Yes but once you convert to a real vi, they look nothing like the express VI interface. I actually want to use the "Configure Mask and Limit" functinality inside of my code. If I convert it to a VI, then the interface has completely changed, and I need to recreate the Vi to get a interface that is similiar to the Mask and Limit Express VI configuration screen.

When run report from form(6i) on the web,error FRM-921000

While I was trying to run report from form (6i)on the web,it will give me this error
message FRM-921000 and hang.
But when I try to call form using form,I do
not have the problem.
May I know ehat is the cause?
Anybody encounter this before?

I am running Forms 6i on the web and attempting to call me report via RUN_REPORT_OBJECT. I am getting the same error as Jenny FRM-92100. I need to pass a parameter list so I don't think I can use WEB.SHOW_DOCUMENT. Any ideas???
Thanks,

Dear Jenny,
I am running reports from Forms 6i on the WEB. I did not encounter your problem. Nevertheless I would like to share the following with you.
RUN_PRODUCT doesn't work for calling reports ON THE WEB. Instead using RUN_PRODUCT do the following:
1. Install Oracle Reports Server
2. For WEB calls of reports use WEB.SHOW_DOCUMENT
3. Learn how to pass parameters to the reports. It is a litlle bit strange, but it is explaint excellent in the documentation to the Reports Server.
I hope this will help you.
