Hello,
I need to write a comment in any time, during the measurement is running.
If it is possible I can write the measuremnet in a excel file insted lvm file. but I don't know how do it.
I must achieve a signal and filter it. then I calculate the integral of this signal and record it in a file.
but I must write a comment during acquisition because the signal change in the time according my manipulation and
I write them on file to have corresponding between comment and values.
This is my VI file I hope it is clear!
Another thing. I would to change file in which write when a write comment to have a diffrent file for each conditions.
Thank you very much

How can I write a comment in a file lvm
I use Write LabVIEW Measurement File to write my signal in a lvm file.
I want to insert a comment and I use a string control to comment.
when I insert a comment I write comment and push Return.
When I open file.lvm there is no comment!!!
Why??
Thank youHi ocramm,
see the attached VI, it's a simple example that writes a single waveform (X and Y axes) in a lvm file adding a comment.
The comment fills only the 1st row of the 3rd column . The position of the comment is always in the 1st row of a new column after the last column of the last signal.
I hope this help you.

How can read/write FORMSWEB.CFG & DEFAULT.ENV file entries programatically?
Environment: Forms 9i (Web)
As : Oracle 9i As
How can read/write FORMSWEB.CFG & DEFAULT.ENV file entries programatically?I guess you cannot. There is an enhancement request to get the name of the config-section as a GET_APPLICATION_PROPERTY.
What you could do is add extra parameter(s) to your form and pass the necessary formsweb.cfg parameters in this form parameter. See Get formsweb.cfg section name in Forms for more info and an example. -

How can I write this string to a file as the ASCII representation in Hex format?
I need to convert a number ( say 16000 ) to Hex string ( say 803E = 16,000) and send it using Visa Serial with the string control in Hex Mode. I have no problem with the conversion (see attached). My full command in the hex display must read AA00 2380 3E...
I can easily get the string together when in Normal mode to read AA0023803E... but how can I get this to hex mode without converting? (i.e. 4141 3030 3233 3830 3345 3030 3030 3031 )

volt to HEX.vi 32 KBSorry, The little endian option was probably introduced in 8.0 (?).
In this special case it's simple, just reverse the string before concatenating with the rest.
It should be in the string palette, probably under "additional string functions".
(note that this only works in this special case flattening a single number as we do here. If the stat structure is more complex (array, cluster, etc.) you would need to do a bit more work.
Actually, you might just use typecast as follows. Same difference.
I only used the flatten operation because of the little endian option in my version.

I had been running other email clients for years and finally switched to Firefox. All the while importing my other email folders. So I had quite a large history of email. I had been backing up my system using Acronis for years. My desktop's motherboard crashed and was not worth repairing. I pulled my desktop hard drive and turned it in a standalone drive. I re-established my email on a laptop starting from scratch using Firefox. I would like to import (if possible) the emails history that is stored on the standalone drive (formerly my old hard drive). However, the names of the mail folders on the drives are different. For example: current computer the mail folder is named garlic.com. On the standalone drive (old hard drive) there are several folders and they are named, for instance; mail.garlic.com, mail.garlic-1.com , and so forth. it goes up through garlic-4.com.
How can I pull or import these older folders into my current email folder and see all my old email archives?You are not going to be able to run your old system from the backup on this old computer as the hardware is incompatible.
You need to get a new computer or a refurbished one. -
How can I suppress @ from prompting in a file when I run slqplus cmnd line
I should know this, but varied searches have come up with nothing :-(
I have a script myscript.sql which inserts data, mostly email addresses such as '[email protected]'. When I run this script command line for example:
sqlplus scott/tiger @myscript.sql
The script prompts me at every @ expecting an input param. How do I escape, ignore, suppress that? Each of the @'s in the file are already either in quotes or comment headers.My bad, you're right - it wasn't the @, it was a completely munged script which dos-to-unix fixed. Although it was odd that I was getting prompted. I'm chalking it up to some weird anomaly. I'm returning to the Oracle world after a 2 year hiatus and dusting off the cobwebs...

How can I read a comment from an lvm?
Hello,
I created an lvm using the Write to Measurement File express vi and I added a comment.
To simplify it the line of the lvm created was:
5 test
where 5 is a random value and test the comment I input.
My question is how can I read this comment.
When I use the Read Measurement File express vi, the comment output
returns empty.
Thank you.
Solved!
Go to Solution.Hi epik78,
I am not sure how you are adding your comment to the file, but when I made the simple VI below, I was able to see the comment that I input to the .lvm file in the comment indicator of the Read From Measurement File.

In my organization, the standard is to comment all stored procedures with a comment block that looks like this:

How can I view all comments in a Pages doc and print the doc with comments?
It seems that we can no longer view comments in the margin of a document. It is also not possible to print the document with comments visible. Anyone else having this problem? Pages 09 Help does not even offer an up-to-date explanation. "Show Comments" only shows color shading. The option “Show Comments and Changes Pane" does not even exist. How can I get the comments to print???
You will have to wait for Apple to fix this deficiency in a forthcoming update to Pages v5. Or, you could use Pages ’09 v4.3, if originally installed before the v5 upgrade, and located in /Applications/iWork '09.
Otherwise, use another solution (e.g. Office for Mac 2011, LibreOffice). -
How can I write a program that compiles without warnings?
I tried the following with the 1.5 beta-compiler (build 28; I think):
class Y {
public static final class Pair<X,Y> {
private X fst;
private Y snd;
public Pair(X fst, Y snd) {this.fst=fst; this.snd=snd;}
public X getFirst() { return fst; }
public Y getSecond() { return snd; }
public String toString() { return "("+fst+","+snd+")"; }
public static void main(String... args) {
Pair[] pairArr = new Pair[10]; // supposed to be an array of Pair<Integer,Integer>
for (int i=0; i<pairArr.length; i++)
pairArr[i] = new Pair<Integer,Integer>(i,i);
for (int i=0; i<pairArr.length; i++) {
Pair<Integer,Integer> p = pairArr; // unchecked warning
System.out.println(p);
Integer first = p.getFirst();
Integer second = p.getSecond();
// ... more stuff ...
It turns out that I get an unchecked warning when I extract an element from the array of pairs. Okay, that's fine. How can I avoid the warning? I had expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer> )pairArr;
With a cast I'm telling the compiler: "I _know_ what I'm doing; please trust me." But the compiler still issues a warning.
How can I write a warning-free program in this case? The only thing I can think of, is not using the parameterized type Pair in its parameterized form. But it's not the idea of Java Generics that I refrain from using parameterized types. What am I missing?It turns out that I get an unchecked warning when I
extract an element from the array of pairs. Okay,
that's fine. How can I avoid the warning? I had
expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer>
)pairArr;
With a cast I'm telling the compiler: "I _know_ what
I'm doing; please trust me." But the compiler still
issues a warning. Yes, but at least you were able to change the warning from "unchecked assignment" to "unchecked cast" which is a little shorter ;-)
Seriously , since arrays of generic types are disallowed, there is probably no way to get rid of these warnings - which makes a strong point for eliminating "unchecked" warnings altogether (see the other thread "selectively suppressing compiler warnings")

How can I Write a sine wave in an Access-file?
I measure a sine wave in LabView 6i. How can I write the datas automatically to an Acces-file, at the same time?
In my program, I managed it with Execute SQL.vi, I change a number in a SQL statement(String) -> after this I push start and then it writes the statement in the Access-file.
The problem is, it writes only one data per measurement in the file. How can I write all datas in the Access-file and measure the wave at the same time?
Thanks for help!
Attachments:
getwave.vi 49 KBOn the waveform palette, you will find a "to components" vi that you can break out the array of the waveform. You can then, using a for loop write all of the values from the waveform.
Better yet, there are examples in the database toolkit manual on pages 3-13 to 3-15 that deal with reading arrays (and even has a waveform example).
Good luck! -

How can I write into a table cell (row, column are given) in a databae?
How can I write into a table cell (row, column are given) in a database using LabVIEW Database Toolkit? I am using Ms Access. Suppose I have three columns in a table, I write 1st row of 1st column, then 1st row of 3rd column. The problem I am having is after writing the 1st row 1st column, the reference goes to second row and if I write into 3rd column, it goes to 2nd row 3rd column. Any suggestion?
Solved!
Go to Solution.When you do a SQL INSERT command, you create a new row. If you want to change an existing row, you have to use the UPDATE command (i.e. UPDATE tablename SET column = value WHERE some_column=some_value). The some_column could be the unique ID of each row, a date/time, etc.
I have no idea what function to use in the toolkit to execute a SQL command since I don't use the toolkit. I also don't understand why you just don't do a single INSERT. It would be much faster.
