Converting decimal to String

Hello,
I want to handle a number stored in a MySQL database as a string. The database type is decimal(5,2). If the decimal portion is .00, then it only returns .0 (1 zero). Can someone help me out?
Thanks!

In our upcoming 10.1.3 (see preview) there is support for providing converters on the direct mapping. This will allow you to specify a specific converter for one mapping or share it across mappings with these same requirements.
In 9.0.4 and earlier I would recommend using the TypeConversionMapping. This allows you to specify that you want your numeric values stored as strings. To control the format you can provide your own ConversionManager at system start-up (ConversionManager.setDefaultManager(new MyConversionManager()) - refer to docs and Java Docs for specific details. The only limitation is that the conversion will be the same for all Numeric->String conversions when writing to the database, instead of per mapping. This is fine for most scenarios I have seen.
There are some additional solutions I have seen used if that does not meet your needs:
- Use your own wrapper class for the numeric value. This wrapper would have a toString() that writes the values out as you expect. Populating it can be done in either the method accessor set method or again with a custom conversion manager.
- In your MySQLDatabasePlatform (assuming you wrote one) you can customize how values are written. This would also limit you one format for all similar types.
I recommend the TypeConversionMapping with the custom ConversionManager and then when you migrate to 10.1.3 you can switch to the more flexible converters on mappings.

Linq to oracle entities - convert decimal to string

hi ,
Im using entityframework beta for oracle
I need compare string to a decimal column in my linq to entities query so i need convert number column to varchar, but .toString is not supported nor Convert.ToString nor SQLFunction.ToVarchar(or something like that) so how can i achieve this? should i import db function or there is some other (easier) way?
Thx for answer

Hi,
I solved it by importing to_char builtin oracle function to my model:
in edmx file put this (to section where your other procedures/functions are ) (change schema attribute to yours):
<Function Name="to_char" ReturnType="varchar2" Aggregate="false" BuiltIn="true" NiladicFunction="false" IsComposable="true" ParameterTypeSemantics="AllowImplicitConversion" StoreFunctionName="to_char" Schema="TOPASFO_DEMO">
<Parameter Name="value" Type="number" Mode="In" />
</Function>
And make partial class of your entities class and put there this:
[EdmFunction("Store", "to_char")]
public string to_char(decimal value)
// don’t need to implement the function
throw new ApplicationException();
And you can call it just like your other imported functions/procedures.

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

Formatting decimal to string

I am having a problem converting decimal to a string. It used to work!!!
My code:
If Microsoft.VisualBasic.Right(Format(nWork, ".000"), 4) = ".000" Then
txtIngrQuantity.Text = Format(nWork, "####")
Else
txtIngrQuantity.Text = Format(nWork, "###0.000")
End If
sample code:
MyStr = Format(334.9, "###0.00") ' Returns "334.90".nWork = 0.5DtxtIngrQuantity.Text is returned as "0,500"Why is it changing the decimal point to a comma?Thanks

Hi Acamar,
My mistake!! It seems that

https://social.technet.microsoft.com/Forums/itmanagement/en-US/dcc9f90d-66b9-492c-b44c-4bff7b7bbcdc/error-in-south-africa-regional-settings-in-windows-server-2012-and-windows-8?forum=winserver8gen
summed it up perfectly
It seems to me that, again, the people "in charge" don't pay any attention to the ACTUAL environment.
Yes, they have "agreed" to change the decimal separator to a comma, without looking at what is REALLY used in the REAL world.
So, it would seem that it is up to the developers in South Africa to circumvent the "experts" and do things in ways that people EXPECT.
I have NEVER used a comma in decimals and I never will - it destroys CSV imports and exports and will never make sense at any level.
My estimation of the so-called experts drops lower and lower when I bump into this kind of rubbish.
The solution is simple: select British locale and change the currency symbol throughout.
Idiotic solution to an idiotic problem caused by idiotic "experts."
I guess that's what we've come to expect from our powers that be!! Another work-around it will have to be otherwise I'll be bumping my head against so many unnecessary problems. Frustrating!
Thanks,

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.
Solved!
Go to Solution.

Try something like this:
(If you can guarantee that the string length is an integer multiple of 8, you an drop the two triangular modes in the upper left. )

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.

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

Is there an easy way to convert from a String with a comma, ie. 1,000.00 to

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!
When performing calculations, also see http://developer.java.sun.com/developer/JDCTechTips/2001/tt0807.html

Converting double to strings

I'm having a problem in getting my double to convert to a string, here's my code so far.
     public void calculatePayments()
          double paymentAmount;
          double monthlyInterestRate = (Double.parseDouble(interestBox.getText())/12)/100;
          double amountOfLoan = Double.parseDouble(balanceBox.getText());
          double numberOfPayments = Double.parseDouble(yearsBox.getText()) * 12;
          paymentAmount = (amountOfLoan * monthlyInterestRate) / (1 - Math.pow(1/(1 + monthlyInterestRate),numberOfPayments));
          Double.toString(paymentAmount);
          tableBox.append(paymentAmount);
And here's the error message I get:
ProgramInterface.java:134: append(java.lang.String) in javax.swing.JTextArea cannot be applied to (double)
          tableBox.append(paymentAmount);
As always, help is appreciated.

This line returns a String but has no affect on paymentAmount.
Double.toString(paymentAmount);To covert the double to String you can save the return in a variable
String s = Double.toString(paymentAmount);
tableBox.append(s);or combine them
tableBox.append(Double.toString(paymentAmount));

Converting double to String

I am looking for a way to convert double to String.
I think that I have to use wrapper like Double class and use toString(double d), but I am not sure how to do it.
Since toString() is static method, I do not have to have an instance of the Double class, so I was wondering what's the correct way to do it.
I need something like this:
String MyString = new String (String1.concat ( My_doubleNumber.Double.toString() ) );
Any Suggestions?
Thanks!!!

WOW thanks a lot. These are definately better than what I thought of doing originally.
In case I need to use the wrapper class somewhere else, I am just wondering what would be a proper use of Double and String?
