Boolean to string convertion

HI,
Is there any tool in labview 8 to convert string to boolean or boolean to string . The source is of boolean type and the sink is boolean type.
Thanks
SR

I don't know why you start a new thread instead of adding to your existing thread here:
http://forums.ni.com/ni/board/message?board.id=170&message.id=193342
In any case, most answers so far have dealt with formatting a boolean into a humanly readable string and back. Actually, I am not sure if that is what you want, because you talk about converting, not formatting.
What exactly do you want to do?
For example if you need to send a boolean via TCP, you need to convert it to a string, but it would make little sense to do any fancy formatting, turning a single byte into a longish humanly readable string. In this case you would just typecast to string, then cast it back to a boolean on the other end.
The image shows one possibility.

Boolean to String - surely there's an wasy way!

How do i convert a boolean to its String represetation?
This is how I do it:
boolean primitiveBool = false;
Boolean objectBool = new Boolean(primitiveBool);
String booleanAsString = objectBool.toString();
Surely there is a shorter more efficient way?
Thanks.

boolean bool = true;
String asString = "" + bool;I think better would be Boolean.toString(boolean) or
String.valueOf(boolean) as you're not creating an
extra, unused String object.Plus a StringBuffer object.Moreimportantly (IMAO), the code is more directly expressing your intent. "Give me a String representation of this boolean" vs. "Give me a String that is a concatenation of the empty string and the string representation of this boolean."

!! help using: public static Boolean valueOf(String s)

I am trying to use this simple function to convert a string value to a boolean. According to the documentation for this Boolean method (public static Boolean valueOf(String s)), this should work:
Example: Boolean.valueOf("True") returns true.
As a test, I tried to run this line of code:
tmp_bool = Boolean.valueOf("True");
I get this compilation error:
test_file.java:10: incompatible types
found : java.lang.Boolean
required: boolean
tmp_bool = Boolean.valueOf("True");
.....................................^
According to the documentation for SDK 1.4, there is a new function:
public static Boolean valueOf(boolean b)
It seems like the commpiler is focusing on this new version of the valueOf() method, and ignoring the case where a String is the parameter. Why won't it use the version that takes a String? What confuses me even more is that I am running version 1.3.1, and the new valueOf(boolean b) function is not mentioned in its documentation.
Am I somehow using the method wrong?
Thanks!

OK, I think I understand now. Thanks.
Let me make sure i have this right...
So basically, if you use variable types of Boolean and need to pass them to methods that take booleans, would you have to call the booleanValue method first?
ex:
Boolean bool_obj;
//example method that takes a boolean
//test_method(boolean b);
test_method ( bool_obj.booleanValue() );
is that right?

String convert

hi
just a stupid question maybe ...
but i'm missing some string convert functions.
e.g. i habe a list with something like:
text(space)text(space)text(spacespacespace)text
and want to convert one (or more) space(s) between the text into ONE tab.
i didn't found any function that makes me able to convert that so that i get
as a result:
text(tab)text(tab)text(tab)text
maybe someone has an idea?
thanks,

Hi Tobias,
use the functions "Scan from string" and "Format Into String"
with the format strings "%s\s%s\s..." and "%s\t%s\t..." like
in the VI attached to this mail.
maybe that helps you
best regards

Binary String convertion.

I've question on binary string convert to array of text/number.
I'm tried to use GPIB read to retrieve a trace of Maxhold data (n number
of frequency) from ESMI Spectrum Analyzer. however, those data always
come out to binary string. So is there anyway i can convert Binary
string --> ascii (in my case, array of number/text), or to retrieve
readable data from the Spectrum Analyzer.
Very appreciate for help.

Incompatible types required boolean found string

I am trying to set a value for a variable called Location when ever the value for the location is "AFRICA"
I need to reset it to be "55555".
What I am getting is that 'Incompatible types required boolean found string' under the if statemant. Can anyone shade some light on this?
String Location = filename.substring(12,17);
String AP = "AFRICA";
System.out.println(Location);
if (Location = AP)
System.out.println(Location);
Location = "55555";
thanks

rp0428 wrote:
The IF condition needs to be a BOOLEAN. The '=' is used to do an assignment. The boolean would be '=='.
But to compare strings why aren't you using
if (Location.equalsIgnoreCase(AP) {
To stress this a little more:
<tt>==</tt> applied between References will compare the Adresses they point to. This means this will only be true if both References point to the identical Object. @Test
testStringEquality(){
String s1 = "my Test"
String s2 = "Test"
Assert.assertTrue("This strings are equal",s1.equals("my "+s2));
Assert.assertFalse("This strings are not identical",s1 == ("my "+s2));
}So use <tt>==</tt> only for primitive number types (those starting with a lower case letter).

How i convert boolean to string ?

which function do it ?
thanks

There is no standard way of converting a boolean to a string, so there is no function to do this (a "True" boolean string can be "1", "-1", "Yes", "T", "True", etc.). You can do this by using a case structure or the Select function from the comparison palette (insert a boolean and output whichever string you want). You can convert it to a variant or to a number and then to a string or you can type cast it directly to a string. In short, it depends on what string you want, but the easiest way is by using the Select function.
This is really a rather basic question. To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

Convert boolean to string

hey
I'm trying to get a drawString(" here I wan't to put the boolean", place x,place y);
It's just so I can check if a part works.
How does this work???
greets

Bert600 wrote:

String s = String.valueOf( boolean );
greetsThe advantages of this approach are:
* You can use the exact same code for any type, as the method is overloaded to cover them all.
* If passing a reference type, you don't need to check for null first. This method does it for you, and gives "null" if the reference is null. Note that this may actually not be an advantage. There may be times when it is incorrect for the value to be null. In these cases, it'd be better to get the NullPointerException than to have the string "null" when you expected a real value. However, in these cases, that reference will probably be used for other things, so the NPE will probably occur shortly before or after this line anyway. Just something to be aware of.

Array of Boolean to String

Hello All,
I have a small coding challenge that has been whipping me all day. I have a 19 element boolean array that I would like to convert to a string without delimiters("0000000000000000000"). Within a for loop I use a "Select" followed by a "Number To Decimal String." Once outside the loop then use the "Array To Spreadsheet String" function on the indexed output. I tried using a blank delimiter input on the "Array To Spreadsheet String" function but that reverts back to tabs. Bummer. I'll keep plugging away trying different functions and constructs, but this feels harder than it really should be. Any fresh prespectives would be greatly appreciated!
Sincerely,
Zach

String convert extended precision

I'm writing a vi that sets a time stamp using the "Get Date/Time In Seconds.vi", converting the time stamp format into a double to get seconds, then I'm saving it as a string to a text file. When I read in the string from the file and use the "Decimal String To Number.vi" the output is limited to I32, which truncates the number to the upper I32 integer limit value of 2^31-1.
Is there a better way to store a time stamp and do a later comparison, or convert the string directly into a double format from the file?
Thanks!

Use the "Fract/Exp String To Number" function, not "Decimal String To Number" which converts strings to base10 integers (as you found out).

How can I preserve display string (convert DOB to Age) upon excel export?

I am using the following code to convert DOB to age within Display String (Format Field/Common tab):
if
//months
(datediff('yyyy',{CDCLIENT.DOB},currentdate)-(if datepart('y',currentdate)>datepart('y',{CDCLIENT.DOB}) then 0 else 1))<2 then
totext(datediff('mm',{CDCLIENT.DOB},currentdate),0,'') & ' months'
else
//years
totext((datediff('yyyy',{CDCLIENT.DOB},currentdate)-(if datepart('y',currentdate)>datepart('y',{CDCLIENT.DOB}) then 0 else 1)),0,'') //& ' years'
When I export to excel/csv/ttx.. it doesn't export the display string (Age), but reverts back to the DOB. How do I preserve this upon export?

Hi Dominic,
The 'display string' formatted values are not exported to Excel Data Only.
Create a 'formula field' as a workaround.

The problem with the strings Convert each other

Hello all,
Could you help me to solve the following problem using LV7.1? Thank in advance.
How can I convert a string of "hexadecimal value" with Normal display style to other string of " the same hexadecimal value" with Hex display style?
Best regards,
Evan_Lv

Hi Evan,
look at the attachment
At the moment there is no error checking (any characters other than (0-9|A-F|a-f) will give an error; only even number of chars is converted). You can do the error checking as an exercise on your own!

Negativ Amount to String convert

hi all
how can i convert a negative amount(example 94.34-) to string. It should after convert like that -94.34.
i want give the amount out in excel, with DOI......
I hope you know, what i mean.....
thx very much

There's no need to use ABS and check the value to determine whether or not to concantenate. One option is to write the value to your character like field then use CLOI_PUT_SIGN_IN_FRONT to move the sign position - it works whether the value is positive or negative...

String convert to list

Hello:
I need to convert a string in a list, I mean:
I have this
text1="list1"
text2="list2"
Now I need to use like parameters.
Showlist text1
On Showlist vlist
list1=[1,2,3]
list2=[A,B,C]
put vlist --I need to show the content on list1 or list2
end
Can you help me please?
Thank you

Hi Arielle,
There are three of ways to do it
1. Use a propList (probably the best approach is you have a
reasonably large list of lists)
On Showlist vlist
lookupList = [:]
lookupList ["list1"]=[1,2,3]
lookupList ["list2"]=[A,B,C]
put lookupList .getAProp(vlist)
end
2. Use a case statement (best for a small list of lists)
On Showlist vlist
case (vList) of
"list1": out = [1,2,3]
"list2": out =[A,B,C]
otherwise
put "Cannot find list " & vList
end case
put out
end
3. Use Lingos "value" command
on Showlist (vList)
aList = value(vList)
-- now do some error checking
if listP(aList) then put aList
else put "Error evaluating vList"
end
