Step looping time interval

LMartin — Fri, 17 May 2013 20:41:44 GMT

Hi Guys,

I'd like to loop on a step (using the looping configuration),

but futhermore, configuring a wait time betweed each iteration...

I haven't found a wait function in the expressions browser, or another way to do that.

Does anyone have an idea to do this?

Thanks for your replies !

TestStand Deployment with Relative Source Paths

shew82 — Fri, 17 May 2013 15:59:55 GMT

Is there any way to set up the TestStand Deployment Utility to use relative paths instead of absolute for source files?

For example, on my system, the TestStand code may be checked out to C:\Users\shew82\Documents\My TestStand Projects, whereas my coworker may use C:\TestStand Projects. In this case, if I create the TSD file, the paths will all be things like "<UserProfile>Documents\My TestStand Project\Project A\Sequence.seq" etc (I believe this level of relative-ness is supported)... The problem is that when my coworkers open up the TSD, he/she needs all of the files to be C:\TestStand Projects\Project A\.... etc.

If instead the files were just ".\Sequence.seq" etc (or even ..\Folder\Sequence.seq) etc then things would pesumably just work... I can't seem to find a setting for this... Am I missing something?

Thanks,

Shaun

Configuring VI Server for LabVIEW Run-Time Engine Adapter

LVB — Fri, 17 May 2013 12:51:11 GMT

I would like to connect to use the desktop execution trace toolkit to debug LabVIEW code modules using the Run-Time Engine Adapter in TestStand. How can I configure VI server when using LabVIEW VI's within the LabVIEW Run-Time Engine Adapter for TestStand?

Adding a GoTo step from the API (C#)

dvtseng — Fri, 17 May 2013 12:47:00 GMT

I'm trying to add a GoTo step in a sequence file using the API commands and am having trouble. I have the unique ID from the step I'm trying to goto, but when I run my code, it always throws an error message "Unknown Variable or Property Name" plus the unique ID of the step I want to goto. The code I'm using to generate the step I want to goto is :

stepTemp.AsPropertyObject().SetValString(strTempData[2], 0, strTempData[2]);

Is there something wrong with my assignment? Also when I was debugging, I notice when I get the unique ID, it always starts with "ID#:" followed by the ID. Do I need to strip this off before assigning?

Thanks.

How to detect any changes of a StepType-field by the sequence ?

FOstyn — Thu, 16 May 2013 08:57:04 GMT

Hi all,

suppose I've got this: a simple StepType 'TEST' with one added custom field 'Source' of the type String.

When using this StepType in a Sequence and editing the 'Source' value (from the Variables panel),

the Sequence name is immediately marked with an '*'. Which is wat we want :-)

But, if I change the 'Source' value from code (C#), I see that my 'Source' value is changed (in the Variables panel), but not that the Sequence has detected this.

Maybe it's StepType-flag that I have to set or from code, executing a trigger or so ?

Thanks in advance ?

teststand 20101 SP1 f1, exception

Freelance_LV — Wed, 15 May 2013 11:34:47 GMT

Hello all

I have been seeing this error since recently, when I run a test sequence in TestStand 2010 SP1, f1. I call dlls made in NI LabVIEW 2010 SP1, f4.

I had been using this test sequence and dll functions since almost two months. but its just since last couple of days that I receive this error. My entire tests runs over days.

There is a dll developed in LabVIEW which, when called inside the test sequence will crash TS. Again, I have been using this dll in the test seq over the last weeks without this error!

I get errors: "TestStand Exception" and "TestStand has to close due to an error". Off late, these errors do not come as often as I get "Memory Manager .cpp" error.

The dll function has been developed using LV 2010 SP1. That is a monitor VI whose front panel will be opened using dll call. I pass a test file name using the dll calls and then the VI will open the TDMS file and display the data till I click Stop.

this TDMS file is being written into, inside a datalogging dll which is also launched from TestStand. This dll is also developed in LabVIEW by us.

I have been using this setup since weeks and now I get this error. Also, I get this after I had upgraded both TS and LV to the latest fixes (f1 and f4).

But the help for this error on NI website actually says we should upgrade to the latest fix inorder to avoid this error! Also there is a post recently for this error found in TestStand 2012.

Is there a version mismatch after the upgrade to respective fixes in LV and TS?

How can I pass a Barcode string from my main GUI to TestStand UUT Information dialog box (Barcode string = Serial Number)?

Angel22 — Tue, 14 May 2013 17:49:04 GMT

Hello All,

I have a GUI that runs teststand application and I want to be able to pass a scanned barcode string to the TestStand UUT information Dialog box Serial Number requirement without having to scan the barcode twice. I just want to be able to scan the barcode only once and that string parse to the Serial Number of Teststand UUT information dialog box and just click ok after I click run sequence button.

What is the best way to do this?

Any suggestion or example that points me to the right direction will be greatly appreciated.

Thanks.

Stan.

Teststand 2012 temp file

Tphan — Mon, 13 May 2013 22:27:34 GMT

Hello

In teststand 2010, I am able to re-directed temp file to a different location by issue this expresion in the PostUUTLoop Calback:

ThisContext.Report.TempFileDirectory= "C:\\tmp"

It does not work with Teststand2012 when I set a similar expression to the PostUUTLoop callback:
Runstate.Report.TempFileDirectory= "C:\\temp"

Please help , it is very anoying to have report "temp" file littering all the test data record folder every where when using the viewer.

Add C/C++ DLL step for "PlaySound" (winmm.dll)

Mikef — Mon, 13 May 2013 14:52:52 GMT

I've been digging through the examples and forum to try to find my answer, but haven't come up with a solution yet.

I currently have a DLL that has a call to the Windows system "winmm.dll" (Windows\System32 directory) into an ActiveX step adapter, I can play a sound. (used C# and VB 6 code in the past)

I use it mostly to play a sound to indicate that my code has hit a "Failed" step for debugging.

I'm trying to re-organize my test systems to make them (there are 2 independent systems) so that I can check them into TFS (source control) and allow them to be absolute path independent, using only relative paths for all of the sequence and DLL calls.

The problem that I have is that I use the same Process Model for both, and I don't want to have an absolute path the the DLL that contains the "Play Sound" function in the DLL. The Process Model is called by TestStand on the top of the stack.

I've been trying to access the "winmm.dll" to play the sound and the "mciexecute" function, but I can't get the step configured in my Process Model ProcessModelPostStepFailure subsequence.

When configuring the Action step (as a "C/C++ DLL adpapter, to the dll, I keep hitting roadblock in that I get errors.

How do I configure this adapter to match the function calls to the "mciexecute".

C# Code uses System.Media.SoundPlayer reference:

//This is called by TestStand
public static void PlaySound(String Path)
{
SoundPlayer spWave = new SoundPlayer(Path);
spWave.Play();
}

and VB 6 code is:

Private Declare Function mciExecute Lib "winmm.dll" (ByVal FileName As String) As Integer

'# Function to Play a sound. Used for Error reporting, or whatever.
Public Function Sound(ByVal FileName As String) As Integer
'Arg: Filename is the full path to a .WAV file to play.
'Play the sound
Sound = mciExecute("Play " & FileName)
End Function

Can this be done through an adapter step in TestStand?

How do I mock up the adapter call correctly for the 'mciExecute" function?

Generating report for Mainsequence & subsequences

NotHon — Fri, 10 May 2013 04:47:46 GMT

Hi All,

Can someone help me to setup or config my teststand software for getting details of failed results for both main-seq and sub-sequences.

I can get the report for Limit test result OK if using in main-sequence however if I have all my Limit Tests in sub-sequence then calling it from main-sequence the report only indicated where is FAILED but not actual Test results.

Thanks

Test Stand File menu item entry point execution in VC++ code

bsnayana — Wed, 08 May 2013 10:29:50 GMT

Hi,

Can you please suggest me, how to execute a file menu item entry point pragmatically in a VC++ code.

My process model seq inserts an item called "Select Model" into TS file menu.

i have to programmatically execute this entrypoint from an Operator interface developed in VC++.

Request your suggestion in this concern.

Performance of context changes

weltaran — Tue, 07 May 2013 17:03:43 GMT

Hi!

I am currently refactoring our process model which has quite a lot more functions than the original (sequential) model. For the SinglePass entry point up to now I had a lot of steps and not many sequence calls (apart from the callback calls) in the sequence. Now I refactored the logical functions of my model into external sequence files and into subsequences within these files. During the SinglePass execution (test program with MainSequence only containing one step) now there are about 50 sequence calls more than compared to the not refactured model (subsequences with just two or three steps are not uncommon). 50 sequence calls means that I have 100 context changes more which I know take some time in teststand:smileysad: However I am surprised that these 100 additional context changes seem take roughly about 310 miliseconds all together (difference of overall test execution time between old model and refactured model).

So my questions are:

- does anybody have experience if there is a difference in context change performance: subsequence is in the same file vs. subseqeunce is in another sequence file (it will take me half a day work to put these subsequences back into the model file)

- does anybody have experience in tuning teststand performance especially regarding context changes (special settings ...).

Up to now I have not yet tried for example to switch off result recording of the subsequences in the sequence properties - that'll be my next attempt.

Thanks so far
