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???

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.

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).

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.

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

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?

Problem with JTree converting Node to string

I have a problem that I cannot slove with JTree. I have a DefaultMutalbeTreeNode and I need its parent and convert to string. I can get its parent OK but cannot convert it to string.
thisnode.getParent().toString() won't work and gives an exception
thisnode.getParent() works but how do I convert this to string to be used by a database.
Thanks
Peter Loo

You are using the wrong method to convert it to a String array.
Try replacing this line:
String[] tabStr = (String[])strList.toArray();
With this line:
String[] tabStr = (String[])strList.toArray( new String[ 0 ] );
That should work for you.

Is there an easy way to convert a long string into an array?

I can convert a long string into a 1-d array by parsing and using build array, but I would like to know if there is a function to make this easier.
For example:
from/   aaaaaaaabbbbbbbbccccccccdddddddd         (string of ascii)
to/       an array that is 1-d with each element having eight characters
          aaaaaaaa
          bbbbbbbb
          cccccccc
          dddddddd
Thank you.

Try something like this:

Converting Datetime in String in map

Hello all,
I am reciving a message from a system A, in which I am receiving field DOB as datetime and I am sending same message to system B , problem is that system B not able to handle DOB at there end as datetime - I have checked at BizTalk side that DOB
is going correct so issue is at system B side. now system B wants BizTalk system to send them DOB field as string.
What could be the possible way's to do this ?
1) We can change both schema System A schema and System B schema and map them is one way .
2) Can we take datetime and convert it to string using some funtoid ? and send that string to system B ? How ?
Is there other way for this ?
Thanks,
Nitin
Thanks and Regards, Nitin.

Hi Nitin,
First find out how the destination system consumes the datatime value. Some system would consume the value in the datetime field as string. It could be the problem in the format of the datetime. Ask them about their expected datetime format. For example
"2004-09-23T10:20:00.000-05:00" is the standard datetime format produced when you set a field as xssd:datetime. May be the destination system not able to handle this format.
If the issue is in the datatype i.e. in the way client consume, the datatype of the destination schema matter:
Then update the destination schema's to have string datetype. And simply map the value from the soruce's datetime field to destination schema's update string field. You don't need any scripting fuctiond to convert the data type. BizTalk's mapper would handle
it.
If the issue is in the date format i.e. in the way client consume, the datatype of the destination schema doesn't matter, and if the actual problem is in the format:
Then update the destination schema's to have string datetype. Use a scripting fuctiond as suggested by others and do the conversion in the script.
If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.

Help with Sample on Converting an XML string to a byte stream

Hello All, I am sure this is something simple, but I am just not figuring it out right now. I am following the sample - "Converting an XML string to a byte stream" from the developer guide since I want to prepopulate just 1 field in my PDF form. How do I reference my form field within my servlet code properly?? I have tried a few things now, my field is within a subform, so I thought it would be <root><subformName><fieldname>My data</fieldname></subformName></root> I have also tried adding <page1> in there too. I am following everything else exactly as given in the sample code. I do have an embedded schema within the form and the field is bound. Thanks, Jennifer

Well, if you have a schema defined in the form, then the hierarchy of your data must match what is described in the schema. So, can't really tell you what it would look like, but just follow your schema.

CIN: Converting a C String to a LabVIEW String

Hi all,
I have been developing CINs in Microsoft Visual C++ 6.0 for LabVIEW as
project needs. However, I am having a problem with converting a C String
to a LabVIEW String in CIN.
I used two ways to try to make the conversion work that were LStrPrintf
and MoveBlock as stated as following:
1. LStrPrintf
#include "extcode.h"
#include "hosttype.h"
#include "windows.h"
struct teststrct{
const char* test;
struct teststrct testinstance;
typedef struct {
LStrHandle test
} TD1;
CIN MgErr CINRun(TD1 *testcluster, LVBoolean *Error) {
char *tempCStr = NULL;
strcpy(tempCStr, testinstance.test); // this would cause LabVIEW crash!
LStrPrintf(testcluster->test, (CStr) "%s", tempCSt
r);
// but if I assigned tempCStr as tempCStr = "test", the string value
"test" could be passed to LabVIEW without any problems.
2. MoveBlock
#include "extcode.h"
#include "hosttype.h"
#include "windows.h"
struct teststrct{
const char* test;
struct teststrct testinstance;
typedef struct {
LStrHandle test
} TD1;
CIN MgErr CINRun(TD1 *testcluster, LVBoolean *Error) {
char *tempCStr = NULL;
int32 len;
tempCStr = (char *)&testinstance.test; //since strcpy didn't work, I
used this way to try to copy the const char* to char*.
len = StrLen(tempCStr);
if (err = NumericArrayResize(uB, 1L, (UHandle*)&testcluster->test,
len))
*Error = LVFALSE;
goto out;
MoveBlock(&tempCStr, LStrBuf(*testcluster->test), len); // the string
was able to passed to LabVIEE, but it was unreadable.
out:
Did I do anything wrong? Any thougths or suggestions would be very
appreciated!

Thank you so much for your response, Greg. However, I still have problem after making
corresponding modification for LStrPrintf approach:
int32 len;
char tempCStr[255] = "";
strcpy(temCStr, testinstance.test);
len = StrLen(tempCStr);
LStrPrintf(testcluster->test, (CStr) "%s", tempCStr);
LStrLen(*testcluster->test) = len;
LabVIEW crashes. Any ideas?

Converting a given string to non-english language

{color:#0000ff}Hi can anybody help me how to convert an entered string in textfield to french or spanish or to anyother non-english language?{color}

Hi,
I don't think you get a language translator package.
What you can do is store the fraises, words in a database.
//SQL Code
CREATE TABLE [Language_Data]
[ID]    INT NOT NULL IDENTITY PRIMARY KEY,
[Lang] VARCHAR(30) NOT NULL,                             //Lang English/French.....
[Type] CHAR(1) NOT NULL,                                 //is Fraise or Word
[Words] VARCHAR(100) NOT NULL                             //Fraise or Word data
GO
CREATE TABLE [Translate]
[ID]       INT NOT NULL IDENTITY PRIMARY KEY,
[FK_Orig] INT NOT NULL REFERENCES [Language_Data]([ID]), //ID of the original language
[FK_Trans] INT NOT NULL REFERENCES [Language_Data]([ID]) //ID's for all known translations
GO Create Stored procedures to add a new word/fraise to the [Language_Data] table,
Create a Stored Procedure to add a translation to the [Translate] table
Please note that to add a translation you will first insert into the [Language_Data] table then
insert the original's ID and the translation ID to the [Translate] table Also make prevision for backwards translation

Converting a binary string to a number...

Hi guys,
I'm trying to convert a binary string into a decimal integer. I'm not sure if LabVIEW has a VI that does that. I haven't found one yet. Basically, say I have the string '0101'. I want to convert that to the value '5'. Or say I'm using hex, I want '10101111' to be converted to 'AF'. So that's my dilemma. I'm hoping I'm not going to have to make my own VI. Thanks a lot!
-Mike

LabVIEW has exactly what you want even if it can be hard to find it.
To convert a binary text string like "0101" to a decimal value can easily be done using the Scan Value function found under the String/Number conversion section. If you provide the format %b to it (not mentioned in the manual) you will get the decimal value of your binary string.
Also, on your front panel you can change the format of your numerical indicators by right clicking on it and selecting Format & Precision. If you have a numerical indicator you can set it do display the numbers in e.g. hexadecimal form.
However, if you want to convert a number to a hexadecimal text string you can use the Number to Hexadecimal String function also found under the String/Number conversion section.
I
attached a simple example, Conversions.vi, that shows how it works. I hope this helps. /Mikael

Is there an easy way to convert from a String with a comma, ie. 1,000.00 to a float or a double?
thanks,
dosteov

Like DrClap said: DecimalFormat. However, make sure you understand the Locale things, as explained at http://java.sun.com/j2se/1.3/docs/api/java/text/DecimalFormat.html (which refers to NumberFormat as well) and use them explicitly. Like
public class FormatTest
public static void main(String args[])
    try
      // see NumberFormat.getInstance()
      DecimalFormat fmt = new DecimalFormat();
      Number num = fmt.parse("1,000.01");
      System.out.println(num.doubleValue());
    catch(ParseException pe)
      System.out.println(pe);
}most likely seems OK on your system, but may print "1.0" (or even fail) on some non-English platforms!
