Scanning string for uppercase letters

Hey guys just a simple question that i'm stuck on. im working on a program and i need to scan a string to see if it has uppercase letters. the only thing i know about that even seems helpful is isUppercase but im not sure how i'd use it. i'm basically generating a sentence form categories which are in uppercase and need to expand the sentence as long as there are categories left. id appreciate any help! Thanks!

     String ts = "i Have a capital";
     boolean hc = false;
     for (int i=0; i < ts.length(); i++)
          if (Character.isUpperCase(ts.charAt(i)))
               hc = true;
               break;
     System.out.println(""+hc);

VISA and Scan string for tokens

Hi there,
I am currently developing a piece of software which needs to take in data from an Arduino board via the serial port and parse the input accordingly.
I have the 2 pieces of code working perfectly well separately, but I can not seem to figure out why they are not functioning properly together.
Just now, the input is being retrieved fine and passed into the Scan string for tokens method, but it is not being split on the tokens, it is just outputting the string as a whole.
The input is in the form of 1:0 2:0 3:1 etc. so I am trying to split it on any spaces found. If I attach a string to the Scan strings for tokens it works fine, just not when I am attaching the data from the serial port to it.
Any help would be appreciated.

Hi,
In the output which you are getting from the serial port, is there space between 1:0 and 2:0 and 3:1? If there is no space between them, then it wont be able to scan for tokens and will output the whole string. I don't have the hardware here and so don't know what exactly is the output which you are receiving. Try to see in the read buffer indicator whether the tokens are seperated by a space or not.
I have attached your vi after adding a small part in it. If the problem is with the spacing then this will work fine for 1:0 2:0 3:1.

Is Scan String for Tokens documented correctly?

I attempted to parse the following string using " as the only delimiter (no operators):
this "is a test" for "you and me"
The first call produced: "this " w/o the quotes.
I expected "is a test" w/o the quotes.
The documentation says the function will return tokens "surrounded by" delimiters. If this is not a bug, I think the documentation should be improved.

Thank you for commenting on the Scan String for Tokens documentation. We will look into this issue and try to make the documentation more clear about how this function works.
We're constantly striving to improve the documentation, so any specific suggestions you have are welcome. In the future, please send any comments on National Instruments documentation to [email protected] so we can address your concerns in a timely matter.

Scan string for tokens

Can anyone help me out on how to detect a new line using the scan string for tokens function? I am using the "\n" delimiter but it is not working

Syntyche wrote:
I opened a text file and display it on string indicator. The following is an example of my text file
START
SETMASS 5
WAIT 5s
SETVELOCITY 10
WAIT 3s
END
So what I want to do is to obtain the string line by line.
I am thinking I can use scan string for tokens with delimeter \n.
So if i put this in while loop, in the first iteration, I would want the ouput to be START
Second iteration: SETMASS 5
Third iteration WAIT 5s. and etc....
In C programming i believe this can be done by using strtok. So i want to have a similar function.
See James' post above, which is what I was hinting at when I said it could be less complicated. And that's why I asked WHAT you were trying to do, instead of HOW. In this latest post, you show WHAT you wanted to do, and doing that in the first place would have made the thread a lot shorter.

"Scan String For Tokens" weird behaviour

I am trying to carry out the simple task of getting a string with
comma delimiters and produce a string_array with the values in between
the commas; this would simplify calling the different parts of the
string.
Example:
INPUT: this,is,an,example
OUTPUT: this|is|an|example (this would be an array of strings)
Using a while loop with the two VI "Scan String For Tokens" and
"Insert to array" should be enough to carry this task. I started
using a FOR loop as the number of tokens I´ll be using is fixed.
However I wanted to make the subVI more general by allowing any
#tokens in the input string and using the token index with a WHILE
loop to do this. The "token index" output from the "Scan String For
Tokens" is said to be use
d in a while loop to process the whole
string.
However,I´m getting -1 as an output even if I´ve got more tokens left
and the while loop therefore exits.
What am I doing wrong?
Should I use -2 as the comparison to decide whether I´m at hte end or
not of the string?
Cheers and TIA

Check the offset for -1, not the token index. (See attached image). If course if this is a multiline string, the you also need /n etc as delimiter.
If the string ends in a delimiter, you need to clip the last array element. I usually use "reshape array" with the output from [n] as input.

Scan string for "returns"

Hi,
I have a multi lined string and want to put it as list into a listbox (i
did it with a for loop and the "i"attached to the line index of the
"pick line" vi) but now a have let my for loop know how many rounds it
must do! How can scan a multi lined strings for "number of lines"?
Regards Thijs

Thijs,
Use the "Spreadsheet String to Array" function (in string functions). Wire
it as follows:
format string: string constant containing "%s"
spreadsheet string: your string
array type: (empty) array string constant
delimiter: string constant containing enter ("\n" with string in code
display mode)
The output "spreadsheet" is an array with strings that can be wired to the
attribute node of the listbox.
Important notice: \n is not the same as \r ! If your string comes from a
..txt file, this can cause unexpected results!

Wiebe Walstra.

Scan string for computer user name

Good morning NI Forums,
I need direction on a file path scan. I'm trying to get to the user name on any system, primarily XP or 7. I'd like to compare the user name from the "Get System Directory" VI with a constant user name.This way I can pass that to a case structure and close LabVIEW if the computer is logged into the wrong user (there are network read/write permissions which is why I need to control where the program isrun from). Any suggestions for the format string constant or maybe a better mouse trap?
I've attached my VI for reference.
Thanks!

String of letters to 1-D Array of strings for spreadsheet

What I would like to do is be able to take this string as it is the A's and B's that are being generated as the program runs,
I would like to take this string and get it into file in delimited tabs just as the numbers are. If there is a created 1-D array of
strings that works, but that is controlled on the front panel, I would like to create this from data that is comming in. In other words
I am stuck on how to create a 1-D array of Sting from the string value comming in. I want to do this so that I can get all the different
values A's or B's into the different tab fields. As it is they are comming all up in the first column and not "tabbing" Please see the
attached file in the rows 5 an
d 7.
Thanks,
Brian

You need to convert your string to contain single tabs as separator. The problem is that your string is "dirty", i.e. it contains a variable amount of spaces to seperate the items. If you strictly had single space separators, you could just replace all spaces with tabs.
"Scan string for tokens" by default does not allow empty tokens, thus takes care of the multiple spaces.
The attached simplified code assumes a fixed number of items (12), if this is a variable, you need to use a while loop and sense the end of the input string. Let me know if this is clear.

Scan String Token Problem with leading Tokens

Hi, I'm using the scan string for token to read in a string of tokens that contain a leading "*" char in front of each string and terminates when the token index = -2. This works great if I have say *12345*1234 and so forth, but if there is bad data, say 1234 without the leading "*" in front, the token index return value is still -1 and it returns data which I read in thinking it found the "*". Maybe I shouldn't use the string for token function since it's probably just designed for ending tokens and not data with leading tokens. Is there a way to make this work properly or should I use another method to search for leading tokens in a string?
Thanks.
Solved!

Here. Try this one. It does the same thing and uses exposed functions.
The string functions look for something to mark the end of a string. All languages that I know of do this. So, like I said, remove the first element. I recommend the Subarray function with the index set to 1 and length unwired.

Labview novice with a question about scanning strings

Hello, I'm a research assistant tasked with taking data received via TCP-IP and plotting it. I've had a couple of problems, probably because I've never used Labview before.
The data is sent in sets of six values separated using semicolons as delimiters, for example
"0.086842;0.00020341;0.00039838;-0.14057;-0.12614;-0.1327;" is one such data set
Receiving these strings through TCP connection is working just fine, however I just noticed that after passing a string such as my example into a 'Scan String for Tokens' block, the negative signs are dropped from the latter three values. I assumed it has something with setting '-' as an operator, but simply wiring negative sign in as an operator didn't change anything. I know there has to be a way to retain my negative signs, but I can't figure it.

Is this what you need?

I purchased an IPAD2 for my special needs daughter. She only currently understands lowercase letters only and gets confused with the uppercase letters. Is there a way to change the keyboard to display lowercase letters?

I purchased an IPAD2 for my special needs daughter. She only currently understands lowercase letters only and gets confused with the uppercase letters. Is there a way to change the keyboard to display lowercase letters?

There is no way for the keyboard itself to display only lower case letters. It doesn't display lower case letters at all for that matter.
When you are using the keyboard - The other issue that you will have is with the shift key. Even with auto caps turned off you can still type capital letters if you tap the shift key and if you double tap it by mistake - it will turn into all capital letters so also turn off Caps Lock in the keyboard settings.
Other than that, there is no way to ensure that you can type in lower case.
Maybe an external bluetooth keyboard would be a better solution but I don't use one, and I have never even seen one in person so someone else will have to verify that for you.

Problem with uppercase letters in Preferences

The following code [excuse lack of formatting]
----- snip ----
import java.util.prefs.*;
public class PrefTest {
Preferences prefs = Preferences.systemRoot();
public PrefTest() {
public void DoIt() {
Preferences myPref = prefs.node("com/MyCompany/MyPackage");
Preferences prefa = myPref.node("MyClass1/Configuration");
prefa.put("MyString", "MyValue");
public static void main(String[] args) {
PrefTest cfg = new PrefTest ();
cfg.DoIt();
----- snip ----
produces the following registry entries [Wndows XP]
----- snip ----
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs\com]
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs\com\/My/Company]
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs\com\/My/Company\/My/Package]
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs\com\/My/Company\/My/Package\/My/Class1]
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs\com\/My/Company\/My/Package\/My/Class1\/Configuration]
"/My/String"="/My/Value"
----- snip ----
As you can see, all the uppercase letters are prefixed by a '/'.
I can see nothing in the docs for java.util.prefs which defines
such behaviour. Is this a bug, a feature or what?
Regards, Alan Beale

OK, I'll reply to my own post, as I think I've found the answer
in case anyone else is interested...
From
http://developer.java.sun.com/developer/technicalArticles/releases/preferences/
-- snip --
You'll see the result of running the code above under J2SE Beta 1.4 for Windows in Figure 1. Note that WML is encoded as /W/M/L, and PreferredChannel as /Preferred/Channel because Preferences has case-sensitive keys and node-names, while the backing store of choice (in this case Windows Registry) does not.
-- snip --
This implies that reading back the prefs should work OK, although the
data in the registry looks ugly. If this is the case [haven't tested
it yet] then it's not a problem.

Hi KS,
In the transfer / update rules you can use a formula to convert lowercase to upper case letters.

Your UserAgent string in Firefox is totally messed up by another program that you installed, and Barclays doesn't know you are using Firefox 3.6.6 - it probably looks like IE 6.0 to that website.
[http://en.wikipedia.org/wiki/User_Agent]
type '''about:config''' in the URL bar and hit Enter
''If you see the warning, you can confirm that you want to access that page.''

Uppercase letters in short name=bad?

Hello,
I was wondering if having uppercase letters in my short name was in any way detrimental. During Setup I must have changed the suggested name and don't want any instability in the future. I'm new to OS X, but I've used linux frequently in the past and have had no problem with login and home/user folder having uppercase letters in them. Thanks.

Thanks very much! I just got scared seeing people talking about Unix conventions not allowing uppercase letters for login names and home folders. (though this never seemed to be an issue in GNU/linux)
