How can I implement a do loop in Test Stand

I'm trying to create a looping step that will execute at least one time like a traditional do loop in a text based language. Can it be done using the loping feature of a single step, or do I have to execute the step, and loop using a goto step with a precondition?
Thanks in advance for any help.

We had a contractor build us an app using TestStand 2.0.1. In the documentation he mentions that the application uses "custom flow control step types that are defined in a TestStand_LabWindow/CVI add-on that is available as a free download from NI". I looked over the original disk and I found a folder containing these step types. You might want to see if you can find them on the web site. Or if is possible here I can attempt to attach them if you want.

How can I implement a dynamic loop rate?

Appologies if this has been answered, but searching hasn't revealed the solution.
I have a data acquisition appliction on the RT clocked externally. I can send every x-th sample to the host PC for display via shared variable (data bandwidth is no issue). I'd like to dynamically determine what "x" should be based on the processor load on the host (I can send x to the RT from the host).
Is there a simple way to determine how much processor time my application is sucking up in the host PC application so I can adapt x to the environment?

Hi Lee Jay!
Thank you for contacting National Instruments. From my understanding of the information you have provided, I think I may have a suggestion to achieve this behavior. However, I am a bit unclear of what you are trying to do specifically. LabVIEW does not have any inherent functionality to determine processor timing and resource usage as you have described. From within the program we can determine the time that elapses from one point to another by using the Tick Count and Sequence Structures functionalities.
Another aspect to consider is trying to use something similar to Queue Basics, which can be found in the Example Finder. This should allow for control over the rate at which items are read at the host regardless of the data coming from the target.
I hope this helps. Let me know if there is anything else I can help with or clarify. Have a great day!

How can I repeat a for loop, once it's terms has been fulfilled???

Well.. I've posted 2 different exceptions about this game today, but I managed to fix them all by myself, but now I'm facing another problem, which is NOT an error, but just a regular question.. HOW CAN I REPEAT A FOR LOOP ONCE IT HAS FULFILLED IT'S TERMS OF RUNNING?!
I've been trying many different things, AND, the 'continue' statement too, and I honestly think that what it takes IS a continue statement, BUT I don't know how to use it so that it does what I want it too.. -.-'
Anyway.. Enought chit-chat. I have a nice functional game running that maximum allows 3 apples in the air in the same time.. But now my question is: How can I make it create 3 more appels once the 3 first onces has either been catched or fallen out the screen..?
Here's my COMPLETE sourcecode, so if you know just a little bit of Java you should be able to figure it out, and hopefully you'll be able to tell me what to do now, to make it repeat my for loop:

How can we implement a regular expression in if condition?

hi,
could any body tell me how can we implement regular expression in if condition?
if a page contains links with .html,.pdf,.img etc as href paths then i should only retrieve the links whose href path is .pdf .
any idea
thanks in advance

Pasumarthi,
Here is some VBA that should do the trick. This was created against the empirix homepage. www.empirix.com.
Private Sub RSWVBAPage_afterPlay()
Dim objReg As New RegExp
Dim objMatch As Match
Dim doc As String
'Get the html
RSWApp.GetHtml doc
'set parameters for regular expression searching and matching
With objReg
    'find all occurances
    .Global = True
    .IgnoreCase = True
    'regular expression pattern specified here
    .Pattern = "a href=(.+?)pdf"""
End With
'Loop through the matches and write them to the results log.
For Each objMatch In objReg.execute(doc)
    RSWApp.WriteToLog objMatch.Value
Next
Set objReg = Nothing
End Sub

How can I get my ES2 loops to play correctly? I keep getting the message that the audio is not found when I drag the loops from my audio browser even though they play fine in the preview.

How can I get my ES2 loops to play correctly? I keep getting the message that the audio is not found when I drag the loops from my audio browser even though they play fine in the preview.

It's exactly as I stated. Whenever I try to drag these kinds of loops (ESX24 / software instrument loops? the ones marked in green with the white music note next to them) from the loop browser into the timeline a message comes up saying Audio Not Found for that loop. And a new track is created automatically when loops are dragged into the timeline, so I'm not creating some other random / synth instrument track so I'm not sure what the deal is... But perhaps I'll try creating a software instrument track first and then drag the loop into that track and see what happens - maybe there's something with the default settings that automatically creates audio tracks whenever loops are imported?

How can I implement a real time datawarehouse

Hi, I'm a little lost here but I want to know how can I implement a real time datawarehouse in sql server, I don't know if it is only to make the extraction process the shortest time possible.
Thank you

Hi Mega15,
I agree with everything Seif and Louw said, but I'd like to add that if you are using SQL Server 2012 or 2014 and you want to use DirectQuery or ROLAP mode (depending on what SSAS mode are you using, tabular or multidimensional) you may be interested on
using columnar indexes on your base tables.
Analytical and aggregated queries will take GREAT advantage from these indexes, they will perform much better than with traditional B-Tree indexes in most of your scenarios.

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO?

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO? It appears as if the Digital I/O modules for CompactRIO are much slower than this.
Thank you,
--Ray

Hi Ray,
The highest frequency input we offer for C Series modules is 20 MHz if you are doing LVTTL and 10 MHz for 5 V TTL. These modules are the 9402 and 9401, respectively. Unfortunately, there is no 80 MHz input on this form-factor.

How can I implement an user function in a derived column of a report ?

Hello,
I've a report and added a derived column.
In this column should be displayed the result of a function.
GETANZGJMONATE ( to_date(#START_AFA#,'DD.MM.YYYY'), #ND#, :P302_GJ );
How can I implement this?
Thanks in advance
Regards Ulrike

Ulrike - I would do this in the SQL statement (there may be other ways).
Presumably START_AFA and ND are table columns?
Presumably you've also created the GETANZGJMONATE function?
So, something like this should work (this also assumes that START_AFA is of a DATE type - you'll need the TO_DATE call if not):
SELECT COL1
, COL2
, START_AFA
, ND
, GETANZGJMONATE (START_AFA, ND, :P302_GJ)
from TABLE
where ...
Can't remember if you have to grant any particular execute permissions on the function ('grant execute on GETANZGJMONATE to public', for example) when you call it from SQL on a page, but you could try that if the function call fails.
Depending on what's in :P302_GJ and what the function parameter data type is, you might need to use the '&P302_GJ.' syntax or TO_NUMBER etc.
Hope this helps.

John.

1. Use structure BAPIPAREX for passing custom fields. (There are several blogs/posts on how to make use of this).
2. In the BAPI i noticed there is a BAdI to populate these fields into your business tables.
Call BAdI MB_BAPI_GOODSMVT_CREATE to fill own fields

How can I implement the connection pool in my java stored procedure

my java stored procedures (in database 'B') have to connect to another oracle database ,let's say 'A'. And how can I implement the behavior like the so-called connection pool in my java stored procedure in 'B', as below.
1. database B, has 2 java stored procedures sp1 and sp2
2. both sp1 and sp2 connects to databse 'A'
whatever I call the sp1 and sp2 and the database 'A' always only one connected session from sp1 and sp2 in database 'B'.
THANKS A LOTS...

my problem is I have a lots of java stored procedures need to cnnect to the remote oracle db, and I hope the remote db can only have a connected session from my java stored procedures in my local db. I try as below
class sp{
static Connection conn=null; //the remote db connection,
public static void sp1(){...}//procedure 1, using conn
public static void sp2(){...}//procedure 2, using conn,too
I can 'see' the 'conn' variable if I invoke the sp1() and sp2() from the same client application(maybe sqlplus). But if I invoke the sp1() from client 'A' and invoke sp2() from client 'B' then the sp1() and sp2() can not see the 'conn' variable for each other. I think it's because the two clients cause oracle to create two instances of the class 'sp' and the sp1() and sp2() located in different instance seperately. Thus the sp1() and sp2() can not see 'conn' for each other. They can only see its own 'conn'.
To connect to the remote db from the java stored procedure is easy but is it possible to connect to the remote db via database link from the java stored procedure at my local db ? If so, then I also archive my goal .
BTW , thanks a lots...

How can I implement IMAQ correlation for 16bit image?

Hi
When using IMAQ correlate. vi in Machine vision Filter catergory, the vi only works for 8 bit source and template image case.
16 bit source image case makes error.
But I need 16 bit source image without losing image information, I want to use full 16 bit image correlation with 8 bit template.
How can I implement the code in labview?
Need help.
Many thanks.

Unfortunately you can't do so.
There are some functions in the Vision Lib that only accept 8bit images. In order to use them you have to convert your image to an 8bit Image.
Keep in mind that converting an Image to 8bit will not necessary result in a loss of data. Check your Images, it might be that you are not using the full range of a 16bit value. you might be able to use a mixture of dynamic shifting and bit shifting in order to convert an image to an 8 bit, then embedding these criterias in the image and use them to convert back to a 16bit at a later time without losing any data, or in most cases minimal precision loss.
If you would like to attach one of the images you are using, I can take a look at it to see if this is possible in your case.
Good luck,
