How I count from 10 to 0 then back to 10?

I am a motor with LabVIEW and I would like to advance a position 14 to 0 in increments of 1 then back up to 14 in 1 increments, and stop there. Any suggestions on how I could set up a loop to do. The routine will be part of a state machine base and whenever I enter this State, that I would like to make the increment.

Thank you.

14 or 10? The subject says 10, but the message says: 14,.

Just keep track of if you count up or down in a shift register. Put 1 in the shift register, if you're out,-1 if you are backwards. Just add this value to the County that you store in an another shift register. When you hit one end or the other, take the negative of it and put it back in the register shift.

How to count from a number

Hello

I am recieveing a number between a VI, and I want to count from the number received up to 1. The number is subject to change.

If it works for you? Would not need a shift register if you're going to go in order.

Should be the last iteration (123-122 = 1). Make sure you take into account that it would be 1-based, so if you use the screw of Excel, you will probably need to decrement to be the zero-based index.

Edit: Do what crossrulz says if your ultimate goal is the release of table, simply load as an array from the outset.

How to count the pulses with digital input on 6351

Hi all experts in Labview,.

I just got my USB x series 6351 and it works fine, but I certainly lack of labview skills to use it to its full potential.

I would like to read digital pulses with several digital inputs and count the number of pulses each T interval in time. All impulses that I entered on any edge of the clock are not synchronized and can occur at random times during the tests. Basically I have an oscillator of square waves can I modulate the frequency. I don't want to use the meter as inputs as I'm limited to only 2 entries (if I use the option 2 input meter for metering of pulses or frequency). The input frequency can range from 0-1 kHz and goes 0 - 3V. So not too fast, and I shouldn't make too many mistakes trying to get the count of pulses and then back out the frequency in accordance with article ni.com on counters.

I would like to read the 8 digital input channels and get the number of impulses for each channel. I searched high and low for help online but can't find examples that have been useful. Anyone have any ideas on how to go or direct me to a resource? Thank you very much in advance!

Are you worried about getting the number as a physical operation timed? It would be nice to acquire a digital waveform and then postprocess on it to detect how many events took place? I've attached an example that shows how you can accomplish this. It reads a digital waveform and then uses a detection of crete VI to determine how many pulses occurred. Should be a few adjustments to your particular signal. The VI I use seems to count events twice (probably count each edge), so counting it gives should be reduced by half in order to work.

How can I get the counts for each parent in a single query

Published by: user7955917 on August 24, 2012 07:26
Generic function how you want the query to be.

If the structure is known in advance, as in your example a 'books' and then a 'library' root element, it's as simple as:
```
SQL> select x1.parent_id, x2.child_name, count(*)
  2  from tmp_xml t
  3     , xmltable(
  4         '/books/bookstore'

  7               , child_list  xmltype path '*'
  8       ) x1
  9     , xmltable(
 10         '/*'
 11         passing x1.child_list
 12         columns child_name varchar2(30) path 'name()'
 13       ) x2
 14  group by x1.parent_id, x2.child_name

How to count the number of data records?

Hey guys, how to count the number of records, I had on a data object variable?
Im having a result of sql query in a variable like this:
oDB.resolveNode("#command").query.select.value = "SELECT * FROM Customers WHERE CliNombre LIKE ' % ' + input1 +" %' ";
oDB.open ();
oDB.first ();
So I need to count the number of records retrieved by this SQL query at the moment. Help please

Then move the cursor back to the first record after you have your account.

There is a keyword count in SQL that will allow you to get the account of your request. You can run that first - get your account, and then run the actual query to get the Recordset. This would require a separate data connection. Some examples of code.

var xfa.event.newText = inName;
If (inName == "") {}
App.Alert ("you must enter a name--try again!")
}
var nIndex = 0;
While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection2")
{
nIndex ++;
}

oDB = xfa.sourceSet.nodes.item (nIndex) .racing var (1); pertaining to the specified data connection node
App.Alert (ODB.saveXML ("Pretty"));

var nIndex = 0;
While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection3")
{
nIndex ++;
}
var oDBCount = xfa.sourceSet.nodes.item (nIndex) .racing (1); pertaining to the specified data connection node
Configure sql call DB to get the number of records that match the criteria

oDBCount.nodes.item (1).query.setAttribute ("text", "commandType");
oDBCount.nodes.item (1).query.select.nodes.item (0) .value = "Select count (*) from table1 where AcctNumber = '" + inName + "'";
oDBCount.open)
oDBCount.close)

Configure sql call DB to get the specified employee number

oDB.nodes.item (1).query.setAttribute ("text", "commandType");
oDB.nodes.item (1).query.select.nodes.item (0) .value = "Select * from table1 where AcctNumber = '" + inName + "'";
App.Alert (ODB. Nodes.Item (1) .saveXML ("Pretty"));

now connect to the DB and get a recording
oDB.open)
oDB.close ();

Note the SQL command use the keyword count (take a look at the oDBCount section). This will return a number of return to the cllaer. When I set up the data connection, a node count (*) that appeared there. I dragged to the form and it has created a field called count that the onus at this node. When the query is executed, the number of resulting records returns to this field. You can have hidden it so that your users can not see it and also to change the binding votes to zero, so it is not included in the data file that is submitted when the form is complete.

Help on query: how to produce from columns of ranks?

Hi all
I have a table table1 with below the structure and data

Item     State          Value
A1      MS          100
A1      GOA          3
A1      UP          4
B2      MS          34
B2      GOA          55
B2      PB          3
B2      DL          4
B3      MS          99
B3      TN          1

I have a requirement to query this table and generate the output below

Item      MS     GOA     UP     PB     DL     TN
A1     100      3     4     0     0     0
B2      34     55     0     3     4     0
B3      99      0     0     0     0     1

The problem here is that we can have multiple status codes, so as a result the query should return dynamically the number of columns

Is it possible to produce above output? Any help will be appreciated.

Thanks in advance!

Hello

This is called a pivot .
The basic technique is something like:

SELECT     item
,     SUM (CASE WHEN state = 'MS'  THEN value ELSE 0)     AS ms
,     SUM (CASE WHEN state = 'GOA' THEN value ELSE 0)     AS goa
,     SUM (CASE WHEN state = 'UP'  THEN value ELSE 0)     AS up
,     SUM (CASE WHEN state = 'PB'  THEN value ELSE 0)     AS pb
,     SUM (CASE WHEN state = 'DL'  THEN value ELSE 0)     AS dl
,     SUM (CASE WHEN state = 'TN'  THEN value ELSE 0)     AS tn
FROM     table_x
GROUP BY  item;

but this requires you to know indicates how many there are, and what they are, when you write the query.

Since you have not, you must run a preliminary motion that will generate a select like the one above, or at least SUM expressions for variable columns. This is called dynamic SQL code , and a technique to do this is included below. (The example uses COUNT, but any aggregate, including the SUM function, work).

Another possibility is the aggregation of the chain, where instead of individual columns for each State, you have a huge column VARCHAR2, formatted to look like separate columns. The avaiable tools to do this in Oracle 8.1 are quite poor, however, so I think you're better with dynamic SQL.

How to Pivot a Table with a Dynamic Number of Columns

This works in any version of Oracle
The "SELECT ... PIVOT" feature introduced in Oracle 11

There will be a separate column for each job.
Each cell will contain the number of employees in

The exact same solution must work with any number

EXPLANATION:
The basic pivot assumes you know the number of distinct jobs,
and the name of each one.  If you do, then writing a pivot query
is simply a matter of writing the correct number of ", COUNT ... AS ..."\
lines, with the name entered in two places on each one.  That is easily
done by a preliminary query, which uses SPOOL to write a sub-script
(called dynamic_pivot_subscript.sql in this example).

The main script invokes this sub-script at the proper point.
In practice, .SQL scripts usually contain one or more complete
statements, but there's nothing that says they have to.
This one contains just a fragment from the middle of a SELECT statement.

Before creating the sub-script, turn off SQL*Plus features that are
designed to help humans read the output (such as headings and
feedback messages like "7 rows selected.", since we do not want these
to appear in the sub-script.
Turn these features on again before running the main query.

How to boot from a USB - Portege R500 flash drive

Hello

I have a Portege R500 running Windows XP, presented about 2 years ago and recently contracted a virus that has infected some of the startup files as the minute I connect it disconnects again, even in SafeMode! The quickest way I can think sorting is to reformat with the XP Recovery disk and reinstall windows.

Problem! The CD/DVD drive on the computer laptop stopped working earlier, tried almost everything in the thread on this site, but had no luck.

So my plan was to boot from a USB flash drive and do it this way. However in the boot parameters I only have the options of HARD drive / floppy drive / CD-ROM / LAN, none of them work. Does anyone know how to boot from USB flash drives?

Any help would be really appreciated

Hello

As far as I know, it should be possible to boot from USB FDD

I don't know if you would be able to boot from a USB flash drive, but it of certainly worth a try m

Generally, you can try to press the F12 key when the laptop is turned on.
A start menu should appear on the screen, then you should see all bootable devices.

PS: as far as I know the USB startup was available in ToshibaHWSetup (tool of Toshiba which changes the settings of the BIOS under windows OS.) So I guess boot from USB must be possible.

How to inherit from Actor.lvclass?

Hi all

I'm playing with the framework of the actor. After reviewing the sample cooler evaporative project, I want to make an absolute minimum example from scratch. I want to open a blank project, manually add a few classes, make them inherit from Actor.lvclass so on (for example not start since the draft framework for actor model).

The first problem I encountered (and not yet resolved) is How to inherit from the Actor.lvclass?.

Time evaporation cooler project (ECEP) example and the project of the actor model framework (AFPT) have some classes already inheriting from Actor.lvclass new classes will have this option of legacy. ECEP and AFPT have also vi.lib-> Framework.lvlib actor in their dependencies.

But how actor Framework.lvlib in my dependencies? I can't just drag C:\Program NIUninstaller Instruments\LabVIEW 2012\vi.lib\ActorFramework\Actor Framework.lvlib with dependencies in my Project Explorer.

However, I can drag C:\Program NIUninstaller Instruments\LabVIEW 2012\vi.lib\ActorFramework\Actor Framework.lvlib in my Project Explorer (like adding a VI to the project). This gives me the ability to inherit from Actor.lvclass and if I remove actor Framework.lvlib in my project again (after a class inherit) it will be listed under dependencies. But I hope that there is a way to better / cleaner to him.

I wish it works when I move the project to another computer with a different labview installation path. My approach above will ensure that Framework.lvlib of the actor is still loaded in the subfolder vi.lib or is it now "hardcoded" aware of my installation path?

Best regards
Jonas CJ

You should read some documents and tutorials on LVOOP, because it is the mechanism that is used. In this case, you must have the responsible actor in the project, so the simplest is the frame screws fall into a vacuum of VI, then go into your properties of the class, go to the legacy page and click the button change. The tree shows you the class loaded into the project, that's why you need the first step for the first class. After that, the class is already loaded, because the other your class inherits from this one, you don't need something it explicit the call.

With respect to the path, vi.lib is a logical path, so it does not work properly when moving between computers and versions of LV.
