Given a multi-line string I want to append a string constant to the beginning of each line.

Thankyou.

You could just use "search and replace" with the search string being "\n" (in \codes display) and the replace string as "constant\n". (See attached image).
If the string you want at the beginning of each line is variable (e.g. line number), you should use e.g. "pick line" or "scan strings for tokens" in a loop, then rebuild the new string.

Hi all ........i want to append some more records to the already released

HI all,
How to append some more records to the already released
scheduled job .how to do this.

HI
process that job once again
because its already completed means the previous records will update but if want to update some more then execute that job once again

I need to sort an array of strings based on the number in each string.

Basically, I have a directory of files that all have the same name but each with a different number on the end.
example: image 1.jpg, image 2.jpg, etc.
When I use the List Directory function that returns an array of strings containing the file names in the directory, they don't come out in a 1, 2, 3, order like they appear in the directory. It sorts them character by character so that they come out like: 1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21, 22 etc.
Is there a simple way of sorting this array of strings with the file names (as above) so that they are in numerical order?

It's a while since this thread was started, but I am sure others will have use for this so here goes:
The in-built array sort function sorts the strings the same way DOS and Windows do. Microsoft has fixed this in the Explorer that comes with XP, however the rest of the OS(s) still sorts the old way.
The attached "AlphaLogical String Array Sort" VIs will sort strings arrays the same way as the new XP Explorer. There are three different implementations of the sorting, one based on the Insertion sort algorithm, a Quick Sort based on recursive calls (the most elegant way, but unfortunately LabVIEW has too much overhead when doing recursive calls so this is actually a very slow alternative) and finally the fastest; a stack based Quick Sort. There is also a test VI that will show you how the different implementations perform.
I had not used recursive calls in LV much until I made the attached quick sort and was a bit disappointed by the fact that it is so slow, but it's a good learning example...The ability to do recursive calls this way was introduced in LV7 I believe...There is an example here on the zone that shows how you can calulate a factorial by using recursive calls, however - unlike for the quick sort (normally) - recursive calls are actually not the optimal solution for that calculation.

Why do you need to put credit card details in to the app store when you may want to simply obtain free items in the beginning?

Apple clearly is a leader and thankfully are bringing fantastic products and initiatives to the market.
I certainly hope that the company doesn't get arrogant like it seems to do when forcing people trying to get free apps to put in credit card details.
I suspect it wouldn't be too much work to allow users to try it out first by using some free apps and when they are personally ready they can purchase to their little hearts desire.
Poor showing from this perspecitive and easy to fix.

Never put your credit card info into iTunes as Apple credit card security is horrible. There are many cases of credit card problems with Apple. My credit card was compromised 2 weeks after creating an Apple account. That was the ONLY online usage of my credit card.
Apple does NOT follow PCI compliance which is the credit card industry standards for credit card data protection. It requires all companies to NOT store credit card information online because (surprise, surprise Apple!) it can be hacked.
Why does Apple need to store the credit card data and put the information at risk and why do they not follow industry (PCI Compliance) guidelines - especially for free aps or updates?

Multi-line string - Array?

I was wondering if someone could tell me how to take a multi-line
string and dump it into an array. I'm assuming that I use the 'Pick
Line' function in a while loop? What do I check for to terminate the
loop?
Thanks...

How do I input multiple string constants into VISA Write

I am trying to put in multiple string commands into VISA Write to control a motor arm. However, when I use "concatenate strings" to link together my multiple string constants, only the first command is executed, and neglects the other commands below it. Should I be using something other then "concatenate strings" or do I need to use a delay so that the next command executes when the one before it is finished? Help.

Concatenate strings should work or just use one string constant with multiple lines. The problem you're having could be that the instrument requires some sort of delay but without details on the instrument, only you or the vendor can answer that. Some instruments will have a queue and others won't. The other possiblity is that you need some kind of termination character between commands. This might be a carriage return for a serial instrument or the ; character for a GPIB one. Check the instrument manual or provide the make and model and maybe someone here has some experience with it.

What is the difference between String Constant and Empty String Constant

What is the difference between string constant which does not contain any value and the Empty string constant?
While testing a VI which contain a normal string constant in VI analyzer, it gives error to change string constant with the empty string constant?
Please Reply

Readability.
Functionally, they are the same. From a coding standpoint, the Empty String Constant is unambiguous.
It is empty and will always be; good for initialization. Also, because you can not type a value into and Empty String Constant, someone would need to conciously replace it to set a 'default' value that is something other than NULL.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

? at the beggining of each line of TOC when I save to pdf?

When I save a Framemaker 11 file to pdf I get a question mark inside of the > character at the beginning of each line of the generated table of contents in the pdf file. I have done everything that I can think of and can't get rid of it.

The right angle bracket is FrameMaker's way of representing the
invisible tab character. That's why it only shows in FM, not the PDF.
You can use Alt v s to toggle display of invisible characters. It's
usually best to leave them turned on.
The question mark is FrameMaker's way of displaying a character that
does not exist in your current font. For example, you might choose a
character to use as a bullet for each item in a list. If you later
change the paragraph to use a font that does not have that character
defined, FrameMaker can no longer display it and shows you a question
mark instead.
So I think you need to look for that character in your file and replace
it with something that will display. If it displays in FM, it should
display in the PDF. Right now, it's displaying in neither. There are two
places I can think of to look for it:
1. Choose the affected paragraph format-- for example, Heading 1-- and
look in its autonumbering properties. Someone may have assigned a
character there. If this was meant to be a bullet, insert the bullet
building block in place of whatever is there now.
2. The other place to look is on the file's reference page (Esc v R).
This is where you set up how FM content displays in generated files.
Here, the paragraph format might be called Heading1TOC, for example.

Whats a String constant pool?

I was reading an article about weak references and came across a peice of code
Map<String,String> map = new WeakHashMap<String, String>();
map.put(new String("Scott"), "McNealey");They also said
if you don't call new String(), the reference for the map key will be to the system's string constant pool. This never goes away, so the weak reference will never be released. To get around this, new String("Scott") creates a reference to the reference in the string constant pool. The string contents are never duplicated. They stay in the constant pool. This simply creates a separate pointer to the string constant in the pool.
I never heard of String constant pool could any one enlighten me. I didnt get the point of what above paragraph says also.
Jubs

No it won't: it will only be removed when the garbage collector rears
its ugly head. Until then the reference will be present in the map.Okay it was unprecise. The item MAY be removed immediately after it
has been inserted because the key object is only referenced from the
Map itself.Yes, that is true, but mind though: any object that still has a strong
reference to it will not be removed from that map. I use such weak maps
for localization reasons a lot. When a localization changes (while the
application is running), a whole lot of visual components must have
their text part changed. They are all stored in such a weak reference map.
Of course quite some visual components can be garbage collected
at some time (think of labels etc. in JDialogs after the dialog has been
disposed).
These maps are ideal for those purposes.
kind regards,

REGEXP_INSTR on a multi line string

Hello ,
I am trying to search through a string that is stored with multi line and trying to find the first occurrence of a character.
For example : The string is -
"This is a sample
text to test
from [first string] to [second string] "
When i try to search for the first occurrence of "[" and "]" regular instr function is returning the complete string
This is the query i used:
The above string is stored in a varchar2 column named - comments
select substr(comments,instr(comments,'['),instr(comments,']')) from my_table
This above query returns : [first string] to [second string]
i assume instr returns the first occurence of a letter in the given string. i was looking for [first string] but it returns me both. Can this be replaced with regexp_instr function?.
Any help on this would be much appreciated.
Thanks

Multi-line String - Match Regular Expression

I am trying to figure out the format of a regular expression in order to pull select lines out of a multi-line string and populate those lines as individual elements of a string array while using Match Regular Expression. The overall length of the multi-line string can vary as well as the text contained within the string. The string can contain letters, numbers, and special characters. I have attached an example VI. Within the example VI I only want to return the lines beginning with "Device #" into the array. The number of lines beginning with "Device #" can vary but I want to capture them all.
Or is there a better function to use instead of Match Regular Expression that will give me the desired outcome?

Match Regular Expression works well for this.

How to discover multi-line of String that will come Flex by Java?

Hi all,
I am programming a little application by using Java and Flex.
One of the functions that Flex contains will have the responsibility to
send the TextArea value to Java as parameter.
But that value could contain multi-lines string. Java recieved successfully but the problem that Java read it as single line.
so, how can I fix this problem?

Hi,
so, is there any solution available right now for my problem.
A text that will come from TextArea that could contains multi-lines
will be sent to Java as paramenter.
How can I distinguish the multi-lines onec I deal with it as String?

Additional results doesn't work with multi-line string dat

I observed an erratic behavior with "Additional Results" in TestStand 2010. The problem statement is as follows:
1. I have a variable "Locals.FirstName"
2. I have another variable "Locals.LastName"
3. Concatenate these two strings with a line feed or a new line character (Locals.FirstName+"\n"+Locals.LastName) and display it in a XML report.
Approach:
1. Using "Statement Expression" I concatenate two strings and print the result using "Additional Results"
2. For verification I display it using "Message Popup" step type. The formatting is as desired in "Message Popup". However, the new line characters appear as "Spaces" in XML report.
Tracing Of this Erratic Behavior:
1. I passed the concatenated string to LabVIEW VI and passed it to "Step.Result.ReportText" variable to log it in XML report. The same string which didn't appeared properly using “Additional Results"of "Statement Expression” step now appears proper in XML report.
I have attached the sequence file for reference. Ensure that Report option is set to XML before executing this sequence.
Can anyone justify this behavior and suggest the correct approach??
Thanks !

Amit -
Here is a modified version of the TestStand 2010 Horizontal.xsl style sheet that corrects the issue you have mentioned. Note that leading and trailing "\n" characters will still be stripped out, and all "\r" characters will be stripped out.
Hope this helps.

Multi line strings - line continuation chars?

Hi all,
I'm not sure if this is a daft question or not...
I need to put a multiline select statement into a string variable.
ie I would like to put the sql below into a variable.
select bla bla bla bla bla
from bla
where bla
strvar := 'select bla bla bla bla bla
from bla
where bla';
Is there a standard line continuation character that I can put at the end of each line to enable me to put the single quote and the beginning of line 1 and the end of line 3? Or do I need to quote each line front and back and cat them together as separate strings?

John

Hi John,
See if this can help you
declare str varchar2(10000);
begin
str := 'select bla bla bla bla bla '||chr(10);
str := str||'from bla '||chr(10);
str := str||'where bla '||chr(10);
dbms_output.put_line(str);
end;
SQL> /
the output should be like below :
select bla bla bla bla bla
from bla
where bla
Anyway new line character is chr(10) for SQL.
Thanks

Printing all text in a multi-line text field?? Can it be done?

I was wondering if there is a way to print out a multi-line field and have all text entered print as well. Currently, anytime someone enters more information in a multi-line text field on our form than is set to show without scrolling, when a PDF is created for printing from the results page, only the text that fits within the specified size prints. You can scroll within the PDF and read it all, but I can't seem to figure out how to get all of the text to show and have that field resize accordingly on the printed copy.
Is there a way? Thanks.

Is there an easy way to determine the character count that is visible in a given multi-line text field when designing the form, so if I want to allow 500 characters, the text box I create is large enough for 500 characters? Obviously I can just do a trial and error process using a cut and paste of 500 characters and testing it, but is there an easier way?

Given a multi-line string I want to append a string constant to the beginning of each line.
