Using Loop to read value

Hello !!
I am detecting rising and falling edge of a square wave in a loop.......but i am not able to do it.....kindly help........sample code is...
Case 1 :
do
Val = readhardware(channel number);
if (val >2) break;
}while(1)

It depends on how your read hardware ( ) function is designed. A tight loop like that is not processing events, so if you function relies in any way in event processing then that system won't work. Can you post a summany code of your function an some detail on how it interacts with the hardware? Does it use serial functions or GPIB or VISA or a third party dll or what?

How to make labview program to get average value of 200 reading from multimeter (by using loop)

Hello
How to make labview program to get average value of 200 reading from multimeter (I using using loop) to read voltage from mulmeter but I like to get average value of all of 200 reding how can I do that?
Thanks

Another idea with less programming - take advantage of the "free" array that comes with a Chart - i.e. the History Data.
1) Wire your DMM data to a Chart. (You can set the chart to invisible if you don't plan on using it in the GUI).
2) Set the Chart History Length to 200 (right click on the chart, click on Chart History Length...)
3) On the block diagram, use the History Data Property Node, wire it to Mean.vi, and you're done.
Easiest running average ever.

1d cluster array replace value in a 1d boolean array (without using Loop)

Hi ,
is there a way to replace the values (string , boolean) of a 1D array Cluster with value of 1D boolean array without using loop ?

Replace Array Subset requires that the array elements are type compatible with the elements that you want to replace. That seems not the case in your example.
And the For Loop is anything but slow. How many billion elements do you expect your array to have to worry about performance of the for loop? With the type definition of your example even a ready made LabVIEW function would have to do internally a for loop too, since the boolean data inside the original array can not be in a continous memory area.
Maybe if you show us what you try to do with the for loop we can understand better what your concerns are. As it is from the front panel image alone it is really hard to understand what your imagined problem might be.

Read values from html response

Hi,
I am trying to make a call to an API using UTL_HTTP POST method over SSL and read the response html page and extract the values from the reponse.
I am able to call and get a response back in html format. I have stored the html response in a clob variable.
Now i want to parse this html and extract values from the form input items and send them out through OUT parameters.
For example, from below reponse i want to extract the value '1111d7nhcwse30wq' from 'I4GO_UNIQUEID'
Can anyone help me with the code to parse this html response and extract the values.
Any help is greatly appreciated.

Problem when parsing html with xpath and xmltype

How to read values from the following XML?

I have been using "extractValue" to get the values from a xmltype field and no problems until now.
The xmltype now is like:
<a>1</a>
<b>2</b>
<c>1221</c>
<c>1412</c>
<d>11111</d>
<e>3333</e>
I'm able to read values from 'a,b,d,e' but not from 'c'.
Questions:
1)- Is posible to read the values of field c?. How?
2)- If is not posible to read the field values, Is posible to transfor the xmlfield to:
Where I will be able to use xmltable columns and loop getting the values.
<a>1</a>
<b>2</b>
<k>
<c>1221</c>
<c>1412</c>
</k>
<d>11111</d>
<e>3333</e>
Like always
Thank you in advance for your help.

Loop over form values & insert into db

FIELDNAMES     prod_id, prod_name, prod_price, prod_status
prod_price     1.00,2.00,3.00,4.00
prod_status    1,1,0,0
prod_id        001,002,003
I want to update a few fields, prod_price and prod_status. I submit these values to my update page but I'm not sure how to loop over these values and update by the prod_id. In my update page I'm using cfdump and I see the structure of the form, the fieldnames as well as the prod_id, prod_name, etc and their values.
My question is how do I loop over these form values so I'll be able to update by each prod_id? I've played around with looping over the form collection values but no luck.

When I do stuff like this, I append the "id" value to the end of each form field. That enables me to ensure the other fields match up.
When processing the form, I generally do something like this:
<cfloop list="#form.fieldnames# index="ThisField">
<cfif left(ThisField, 9) is "prod_name">
<cfscript>
ThisID = removechars(thisfield, 9);
ThisName = form["prod_name" & ThisID];
same for other fields
Then do something with those variables.

How to loop to get value of all checked checkboxes?

I am a non-techic trying to fix something for work. Your help is really appreciated.
I have a form with checkboxes (4 check boxes). Everything sumbits fine. SQL db is updated perfectly and data is displayed on webpage w/o any problem. However when I go to edit an entry, on the edit form, (if more then one checkbox were selected oringally), non of the checkboxes are checked. If only one checkbox was selected orinally, that checkbox is selected. What am I missing? I know I am suppose to use loop to get all checked checkbox values, but I have no idea how.
Here is my code so far.
<input type="checkbox" name="colors" value="red" <cfif #getResultSet.colors# EQ "red">checked</cfif>>red
    <input type="checkbox" name="colors" value="blue" OR<cfif #getResultSet.colors# EQ "blue">checked</cfif>>blue
    <input type="checkbox" name="colors" value="green" OR<cfif #getResultSet.colors# EQ "green"></cfif>>green
    <input type="checkbox" name="colors" value="yellow" OR<cfif #getResultSet.colors# EQ "yellow">checked</cfif>>yellow

You've given all the checkboxes the same name. Give them each a unique name and you will be able to access them individually. Current standards also require a unique ID, which can (but does not have to) be the same as the name.
The "OR" characters in your code are not doing anything. You can safely delete them.

How to insert null record (some col) in table using loop

Hi,
How to insert null record (for some columns) in table using loop.

You have a table
   CREATE TABLE tab (
      col1 NUMBER,
      col2 NUMBER,
      col3 NUMBER,
      col4 NUMBER
      col5 NUMBER)Now you insert:
   INSERT INTO tab (col2, col4) VALUES (5, 7);col1, col3 and col5 are NULL by default (there is no DEFAULT clause for these columns so they are NULL).

It's interesting that some other guy asked about a for loop like that a week ago. (http://forum.java.sun.com/thread.jsp?forum=31&thread=323439) Are you the same person with a different name? Or are you taking the same course?
As I said when I answered that question, and as should be pretty selfevident if you actually understand what the for loop you have is doing, you can select which word you print out by changing the initial value of 'i' in your loop. To print word number 2,12 etc you set 'i' to
9 at the start.

Loop and read issue

Hi Experts
I am trying to do basically as shown below
LOOP AT T_EDID4 INTO WA_EDID4 WHERE DOCNUM = T_EDIDC-DOCNUM .
READ TABLE T_EDID4 WITH KEY DOCNUM = T_EDIDC-DOCNUM
                            SEGNAM = 'E1KNVVM'
if sy-subrc eq 0 .
endif.
endlloop.
If there are more than 1 E1KNVVM for idoc number , how can i make sure not to read the segnam which has already been read

Sanju,
While extracting the data into T_EDID4 take the data of "SEGNUM" column from EDID4 table.
SORT : T_EDIDC BY DOCNUM,
            T_EDID4 BY DOCNUM SEGNAM SEGNUM.
LOOP AT T_EDIDC.
   LOOP AT T_EDID4 INTO WA_EDID4 WHERE DOCNUM = T_EDIDC-DOCNUM
                                                             AND   SEGNAM = 'E1KNVVM'
                                                             AND   SEGNUM = T_EDID4-SEGNUM.
      if sy-subrc eq 0 .
       endif.
endlloop.
Don't forget to reward if useful...

In case you did not find it, the following is a copy/paste of the Announcement on Premiere Elements 19/NVIDIA GeForce
that appears at the top of this forum.
Premiere Elements 10 NVIDIA Video Card Driver Roll Back
If you are a Premiere Elements 10 user whose Windows computer uses a NVIDIA GeForce video card and you are experiencing
Premiere Elements 10 display and/or unexplained program behavior, then your first line of troubleshooting needs to be rolling
back the video card driver version instead of assuring that it is up to date.
Since October 2013 to the present, there have been a growing number of reports about display and unexplained workflow
glitches specific to the Premiere Elements 10 user whose Windows computer has a NVIDIA GeForce video card. If this applies
to you, then the “user to user” remedy is to roll back the NVIDIA GeForce video card driver as far as is necessary to get rid of
the problems. The typical driver roll back has gone back as far as March – July 2013 in order to get a working Premiere
Elements 10. Neither NVIDIA nor Adobe has taken any corrective action in this regard to date, and none is expected moving forward.
Since October 2013, the following thread has tried to keep up with the Premiere Elements 10 NVIDIA reports

Using Loops with INDEX BY BINARY INTEGER

Hi,
I have a little question with the next procedure:
                               SET SERVEROUTPUT ON
                            DECLARE
                               TYPE dept_table_type IS TABLE OF hr.departments%ROWTYPE
                                  INDEX BY BINARY_INTEGER;
                               my_dept_table   dept_table_type;
                               v_count        NUMBER (3)     := 160;
                            BEGIN
                               FOR i IN 100 .. v_count
                               LOOP
                                  SELECT *
                                    INTO my_dept_table (i)
                                    FROM hr.departments
                                   WHERE department_id = i;
                               END LOOP;
                               FOR i IN my_dept_table.FIRST .. my_dept_table.LAST
                               LOOP
                                  DBMS_OUTPUT.put_line (my_dept_table (i).department_name);
                               END LOOP;
                            END;                               When I run this procedure I get the following error:
ORA-01403: Not found any data
ORA-06512: line 11But I Know why is it, the department_id numbers are (100,110,120,130,140,150,160) and the first loop it's ok but
in the second loop the 101 department_id doesn't exist an then it fails.
what can I do to resolve this error?
thanks in advance!!

Reading values from lookup columns through custom workflow in SharePoint 2013

We are able to read the values of text, number columns through custom workflow (via coding) in SharePoint 2013. However, we are not able to read values from lookup columns. So, request anyone to provide help on this.
Thanks & regards,
Aditya

Hi,
According to your post, my understanding is that you want to read values from lookup columns through custom workflow in SharePoint 2013.
Since the workflow just doesn't get lookup fields, let's give it something static to work with instead. If we can capture the ID of the lookup field and store that as a static value in our list, the workflow can happily use that to look up our related.
For more information, you can refer to:
SharePoint 2013 Workflows and Lookup Columns
