IVI FGEN resets frequency to 1k before each run

I'm using an Agilent 33220A function generator through the IVI FGEN Standard Function. I'm using a Sweep step to step through a range of frequencies. Everything's working great except that each time I start a run, the 33220 is reset to 1kHz. (I'm sweeping from 25990 to 26010 Hz.) Is there any way to keep this from happening? I tried setting the Frequency parameter in the IVI FGEN step to 25990, but that didn't help.

Hello Steve,
There should be a VI in the 'Getting Started' example called 'Initialize with Options'. Open that VI up and see if there is a true constant wired to the 'Reset Device' terminal. If there is, that is the reason that your sweep reinitializes every time.
Thank you

How to reset indicators in a control design and simulation loop before each run?

Hi,
I am new to Labview. I have tried using property node to reset indicators before each run. But since it is in a simulation loop, it gets resetted many times. I am primarily interested in resetting only before each run.
Any hint will be of great help.
Thank you!

Divya

Hi Divya,
This KnowledgeBase article describes 2 methods for resetting your Front Panel programmatically:
http://digital.ni.com/public.nsf/allkb/08E7DDAE66A7D02C86256DDA00630E75
However if you have tried these methods, and are still not getting the behaviour you want, it would be easier to help if you could post your code (or even a screen shot of the section of code where you're trying to reset your values)

Need to 5 spaces before each paragraph and 5 lines between paragraphs

Hello,
I need to write a program to insert 5 spaces (indent) before each 1st line of the paragraph and 5 spaces between each paragraph....I am new to java so I don't understand everything I write and I try and use what is out of the book...so far have done well until this assignment. My program below does create a new history.d2 file but it is blank....anyone have any input to offer or can you help me understand where I am going wrong in the program....thank you kindly.
I am playing with the program now just to see if I can find my error but of course don't fully understand the function of every line so having trouble finding my error.....at the end of my program is the file of what I am trying to edit into the new file history.d2.

The Abacus (which appeared in the sixteenth century) was the
first calculator. In the middle of the seventeenth century
Blaise Pascal, a French mathematician, built and sold gear-
driven mechanical machines which performed whole number
addition and subtraction. (Yes, the language Pascal is named
for him.)
Later in the seventeenth century a German mathematician
Gottfried Wilhelm von Leibniz built the first mechanical
device designed to do all four whole number operations:
addition, subtraction, multiplication and division. The
state of mechanical gears and levers at that time was such
that the Leibniz machine was not very reliable.
It wasn't until the nineteenth century that the next major
step was taken, this time by a British mathematician.
Charles Babbage designed what he called his analytical
engine. His design was too complex for him to build with the
technology of his day, so his design was never implemented.
His vision, however, included the important components of
today's computers. His design was the first to include a
memory so that intermediate values did not have to be re-
entered. His design also included the input of both numbers
and mechanical steps on a type of punched card developed in
the late eighteenth century by Joseph Jacquard to be used
with a mechanical loom.
Ada Agusta, Countess of Lovelace, was a most romantic figure
in the history of computing. Ada, the daughter of Lord Byron
(the English poet), was herself quite a mathematician. She
became interested in Babbage's work on the analytical engine
and extended his ideas (and corrected some of his errors).
Ada is credited with being the first programmer. The concept
of the loop--a series of instructions that repeat--is
attributed to her. Ada, the language used by the Department
of Defense, is named for her.
During the later part of the nineteenth century and the
beginning of the twentieth century advances were made
rapidly. William Seward Burroughs produced and sold a
mechanical adding machine (that worked!). Dr. Herman
Hollerith developed the first electro-mechanical tabulator
which used a punched card. Data was represented by holes
punched on the card in certain positions. Descendants of
this card are still in use today. Dr. Hollerith formed a
company that is known today as IBM.
In 1936 a theoretical development took place that had nothing
to do with hardware per se but profoundly influenced the
field of Computer Science. Alan M. Turing, another British
mathematician, invented an abstract mathematical model called
a Turing machine, laying the foundation for a major area of
computing theory.. The most prestigious award given in
Computer Science (equivalent to the Fielding Medal in
Mathematics or a Nobel Prize in other sciences) is the Turing
Award, named for Alan Turing. A current Broadway play deals
with his life. Analysis of the capabilities of Turing
machines is a part of the theoretical studies of all Computer
Science students.
By the outbreak of World War II, several computers were under
design and construction. The Harvard Mark I and the ENIAC
are two of the more famous machines of the era. John von
Neumann (an American mathematician this time) who had been a
consultant on the ENIAC project started work on another
machine known as EDVAC which was completed in 1950. In 1951
the first commercial computer, UNIVAC I, was delivered to the
Bureau of the Census.
Von Neumann is credited with the development of two very
important concepts. The first is that the instructions that
operate the machine should be stored in the machine along
with the data to be operated on. The second is that data
(and instructions) should be represented in the binary number
system rather than the decimal number system.
The general organization of a computer has remained constant
over the last 40 years. This organization or architecture is based
on the ideas of von Neumann and bears his name. The
essence of this architecture is sequentiality. That is,
instructions (a program) are stored in sequential memory
locations in binary form and are executed in sequence, one
after the other.

Each paragraph is terminated in your text file by a newline character. So effectively what scanner.readLine() is doing is reading a paragraph of text.
1. Read paragraph into String (readLine())
2. Print or prefix 5 spaces to String.
3. Print 5x newline character

I have a column in a Numbers document that currently only contains a number--the numbers are different in different columns. Before each number I want to add the words "Pack Qty." How would I do this?

I have a column in a Numbers document that currently contains a number and that number is different in different columns. I want to add the words "Pack Qty" before each number in the column. How do I do that? I'm using Numbers '09 on a brand new Macbook Pro. Thanks!

In an adjacent column add the formula:
="Pack Qty: "&<CELL>
where <CELL> is the cell in the same row where the quantity is,
Like:
E2="Pack Qty: "&D2
select, and hold, the little circle at the bottom right corner of the selction, then drag down

Why RandomAccessFile inserts space before each character while writing?

Ater running the following code, the file test.txt contain:
a b c d e f g h i j k l m n o p q r s t u v w x y z
Why writeChars() inserted a space before each charecter?
How to avoid this unwanted insertion?
try {
RandomAccessFile raf = new RandomAccessFile ("c:/test.txt", "rw");
raf.writeChars("abcdefghijklmnopqrstuvwxyz");
raf.close();
catch(Exception e) {
System.out.println(e.getMessage());
}

a char in java is a 16 bit datatype. (Allowing special chars like Norwegian �� , German �� and many more from many languages). The ASCII system uses bytes for characters. (Allowing only 256 different chars). If you reed the file as byte you must write it as bytes as well. If you write the file as chars (16 bit cars) you must read the file as (16 bit) chars as well.

Apex form - asking password before each screen!

Hi
I am developing a multi-page application.
My intention is, user will specify username password in log in screen. Then a menu (tree) will be shown. Clicking on each menu item, he will navigate to different pages.
The problem is, each time user clicks on menu to go to any page, the log in prompt is coming before each page!
How can I make it so that asked only at beginning and until user logs out, it won't be asked again.

HT201263 My phone screen is cracked and my LCD is broken. I need to reset to factory settings before I discard it, how can I do this?

My phone screen is cracked and my LCD is broken. I need to reset to factory settings before I discard it, how can I do this? I was able to get it into recovery mode, I unconnected it from my Find my iPhone (i couldn't erase that way because I can't connect to WIFI with the screen not working). I clicked restore iPhone from iTunes, but it's been sitting on "Contacting the iPhone software update server..." for over 40 minutes. Should I restart this process or is it supposed to take a really long time? Thanks!

Add the title before each Report

Hi Experts,
For a requirement I need to combine 3 reports into a single template using Web application designer,
The title should display for each of the reports.
I do not have any standard template.Its a combination of 3 reports and is displayed in the same page.
My requirement is to how to add the title before each of the 3 reports .
Many Thanks,
Vijaya.

Hi Vijaya,
You can have the Analysis or the Table item with a Tray. i.e; You can enter a name for the report in the Tray.
You will find the Tray in the Properties of the Web Item. Its mainly used for naming purpose.
Or else you can have a Text Web Item corresponding to each of your reports. 3 Report 3 Text items. Text item is found in the Standard Tab in WAD 3.5 or under Misc. Tab in WAD 7.
Bind the Text Element to the respective Reports and give it a name.
Place the Text item above the report in the template.
Cheers,
Tanish

HT6058 I have updated my I pad dut I'm still having problems my iPad seems to freeze and when I go to put in my pin it take a few seconds before the numbers go in and my games stop and start and stop and start for a bit before they run properly

I have updated my I pad dut I'm still having problems my iPad seems to freeze and when I go to put in my pin it take a few seconds before the numbers go in and my games stop and start and stop and start for a bit before they run properly

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

Waveform Graphs: Is there a way to save data to a file and then clear the graph after each run?

This is just an added feature that I would like to insert because I end up having to erase the previous graph(for viewing and simplification purposes) after almost every plot cycle. Does LabVIEW 7.0 have a built-in feature that allows the user to automatically clear the graph after each run.
Thank you,
Keith Blackwell

May I recall you that to clear a graph you have to create a property node,
choose value and connect an 1D array with its first value to zero.
Then using a Select vi enables you to choose from clear or graph value.

How to schedule a job to run after completion of each run using DBMS_JOB ?

Hi Gurus,
Please let me know if the subject requirement can be fulfilled. I want to schedule a job using DBMS_JOB to run a script sequentially after completion of each run.
Thanks in advance.
Santosh

Hi Santosh
Instead to use the old dbms_job package use the dbms_scheduler and raise / catch events.
Oracle create dbms_scheduler also for this purpose you need.
You can find tons of examples on the web.

With multiple devices (.g, .n, .ac) will the Time Capsule degrade to the lowest speed, or will each run at the highest rate it is capable of?

With multiple devices (.g, .n, .ac) will the Time Capsule degrade to the lowest speed, or will each run at the highest rate it is capable of?

Highest rate capable.
Things may slow down a bit if you have a number of wireless devices connected simultaneously, since they must all share the same network bandwidth.

How do I get my controls and indicators to clear after each run of the VI?

I am using LabVIEW for my Senior Design Project in EET for Purdue University-Indianapolis. After each run of my VI, I want the controls and indicators to go back to their default state (cleared). I don't see an option for this. For example, I have a password VI that allows a user to log in. Once this sub-VI is rerun, the password from the previous user is still there. How do I clear this??? after each run???
Thanks, D

Use the property node and invoke node to clear.
In your block diagram,
Function Platte.
>Application Control
>>Invoke Node
Then right click the invoke node..
>From "select VI server class" option
>>choose "VI"
Then right click again
>From "method" option
>>choose reinitialize all to default
That will reinitialize all your value to default
if you want to reinitialize only your password to default then its simple
right click the invokenode agian
>From "link to" option
>>Then link your invoke node to any control or indicators
I attach one simple file for you
Hope that will work..
