Number to fraction string +format value

Hi there,
I just met a stupid question which made me crazy, please help.
The question is simple:
Target: Numeric floating control-> number to fraction string -> format value -> desirable string format
For example: 20.00 -> 20.00000 (Q1: why extra 0s?)-> "20.00"
I use the following program:
why doesn't it work, please?
Thanks!

Hi TriStones,
"Why it doesn't work?"
Because you haven't read the context help for "Number to fractional string"! Especially the sentences on those two additional inputs of that function (Q1)...
I would suggest using FormatIntoString like that:
(I tried to replicate your example, but your wiring is very bad: it's not clear which wire is connected to which input...)

Thanks for ther reply
Ranjeet singh,
number to fractional string is working correctly, there is some other problem, because inly when i am executing this code converting this rise time value to string then only it is showing zero, otherwise for any random number if i am checking this number to fractional string is working correctly.
Norbert_B
i dont need to convert it back to string that i am doing only to check why it is showing zero value on converting number to string , because when i was writing to spreadsheet file it was always writing zero value, so when checked that code it was observed that while converting from array of numbers to spreadsheet string it is always writing zero value that's why i am doing it here just to check why it is not converting to string, but your suggestion helped in focussing the string that i am gettong from VISA read, i can use that in last case if i wont be able to find the solution but main problem is that why i am not able to convert it back to string, why it is showing zero because it is because of this only write to spreadsheet is always showing zero value .

Hi 23235573,
why not? The context help describes what this function do. You can convert a number to a fractional string.

Converting string format of a number to numeric.

Hi,
I use the NumberFormat classes to convert a number to it's string formatted representation in the given locale. How do I achieve the opposite?
I mean, how do I convert a String value of +"23,233,23"+ to an integer value 2323323?
Thanks.

I use the NumberFormat classes to convert a number to it's string formatted representation in the given locale. How do I achieve the opposite?Have a look at the parse() method of NumberFormat.

In fact it's about mac:excel, how convert in a cell a number written in text format into a value?

how convert in a cell a number written in text format into its value?
cheers francois

Hi francois,
If I copyone of them and do a past special/value, it does not work.
Try just Paste instead of Paste Special > Value
I know your question is about Excel, but this works in Numbers:
Copy 1 234 567 (with spaces) and Paste (not Paste Special) into a Cell in a Numbers Table. The result is 1234567 and it behaves as a number. A formula will consider it to be a number:
You asked Wayne: what do you mean by "to reference a cell" ??
The reference is from Cell A2 to Cell A1 through a formula, such as: =A1+1

Method to test if the value is a number or a string?

Hi Everybody !!!
Do you know a method that permit to test if the value is a number or a string?
Thanks !!!

What kind of value is it? Is it a String and you want to test if it holds a number or characters? If so, use toCharArray() on the String to convert it to a char array and use Character.isDigit() and/or Character.isLetter() on each of the char array elements to test it's type.

Conversion: engineering string to fractional string

Hello everyone
I am loading a text file with several columns that has text (informations about the file and column titles) and values in engineering format. After I load this file I use "spreadsheet string to array" to convert it to 2D array of strings.
I would like to leave all the "text" (informations about the file and column titles) unchanged, but I want all the "engineering values" to be converted to "fractional values". How do I convert an engineering string to a fractional string?
I will have to convert the whole file at once because different files have different positions for text and engineering values and because of that would be impossible to know the index of values and convert just them.
Thanks.

Hi Dan,
conversion is done like that:
But you have to select, what is text and what is number, on your own. How should LabVIEW know about your file format?

Pad leading zeros in a string.Format function

How could use the string.Format function and in the format text pad a leading zero?
Pseudo code is:
string parm = “5”;
string format = “Some number formatted as 3 dig: Format({0}, 000)”;
string output = string.Format(format, parm);
Where the output would look like this:
“Some number formatted as 3 dig: 005”
Thanks.

Thanks everyone. Unfortuantly there's a constraint where the padding operation needs to be embedded in the format string. This entire operatin is being put together dynamically where the format strings are being pulled from a library of format strings stored
in a database. at runtime we don't know how which format will be used and how many parameters will be passed in. we have logic to handle the unknown number of paramters as there is metadata which helps us with that.
the need for leading zeros needs to be part of the overall format defined in the format string. for example, a real format string stored in the database looks like this:
"LINE_NO = '{0}', AND GEO_LOCATION = 'T{1}, {2}, R{3}, {4}, , Sec. {5}'"
and its output from the string.Function is:
"LINE_NO = 'TG-G2469', AND GEO_LOCATION = 'T155, N, R93, W, , Sec. 5'"
the last parameter (param 5) had a value of 5. In another case the output requirement might need to look like this:
"LINE_NO = 'TG-G2469', AND GEO_LOCATION = 'T155, N, R93, W, , Sec. 05'"
note the "05" at the end...
the logic of using the leading zero needs to be embedded in the overall format string text.
Thank you.

How to get formated value from query

i get value from query use the follow method
Object obj1 = dataAccess.getValue(i,j,DataMap.DATA_UNFORMATTED);
Object obj1 = dataAccess.getValue(i,j,DataMap.DATA_FORMATTED);
the first method retrun a value '1666.0',
the second method return a value null
but i want to get the value '1,666'.
who can tell me how can get the formated value?

Ahu,
An implementation of DataAccess is not required to support all DataMap constants. For example, the OLAP-based Query object does not support DataMap.DATA_FORMATTED. To find out which DataMaps are supported for a particular implementation, you can call the DataDirector's getSupportedDataMap method.
If you have an Crosstab instance, there is a way to get the formatted cell value, based upon the formatting rules associated with the Crosstab. Get the GridViewFormatManager reference from the Crosstab, and call its formatDataValue method to return a String representation of the formatted data value.
Hope this helps,

How to check the current time with a Stored time in string format

Hi All
I would like to compare the system time with an existing time values which is allready there in String format..
i mean i would like to check if the SysTime is inbetween 6:30 and 14:00
I accomplished this in Oracle ..
Select 'Y' from dual where to_date(to_char(sysdate,'HH24:MI '),'HH24:MI') between to_date('06:30','HH24:MI') and to_date('14:00','HH24:MI')
But instead of checking the DB each and every time , the perfomance would be better if we can do this in our java code..
Could some one provide me with a code to accomplish the above scenario..
Thanks in advance..,.,

import java.util.Calendar;
Calendar rightNow = Calendar.getInstance(); // gets the current date and time to millisec
Calendar earlyTime = Calendar.getInstance().set(Calendar.HOUR_OF_DAY, 6).set(Calendar.MINUTE, 30);
Calendar lateTime = Calendar.getInstance().set(Calendar.HOUR_OF_DAY, 8).set(Calendar.MINUTE, 0);
if (rightNow.compareTo(earlyTime)> 0 && rightNow.compareTo(lateTime) < 0){
// do something
}Try this.

Conversion of String key value to type Key

I retrieve the key for the selected row from my page event in a java program. It gives it to my in
String format and I need it in Key format so I can use it in Row cRow = vo.getRow(rowKey);
How do I convert the string version of the key to type Key.
Thanks, Steve

There doesn't seem to ge a getRowFromKey() function in uix. bc4j has something that seems similar called findRowByKey.
I set it up in the null event handler as follows:
    <bc4j:findViewObject name="SmFrameworksEdit" >
      
        <bc4j:findRowByKey>
          <bc4j:keyBinding>
            <bc4j:propertyKey name="key" />
          </bc4j:keyBinding>
          <bc4j:handlers>
            <method class="smart.SmartUtilities" method="setSelectedFrameworkName"/>
          </bc4j:handlers>
        </bc4j:findRowByKey>
      
    </bc4j:findViewObject>I tried it both with findRow and without and the same thing happens. When I launch the application from JDeveloper, and go to the page that executes the null event handler, the current row is null.
The second time through, the row that shows up is the one I selected the first time. After that, it stays with this value and does not change.
I print out the contents of my page and event variables and I can see the key changing, but the row itself gets stuck on the one row that is called the first time through.
Any ideas on what is going on?
Thanks, Steve

Convert a date in String format to a Date

Hi,
How can I convert a date in String format to a Date object?
I have tried:
import java.text.*;
import java.io.*;
import java.util.Date;
import java.util.Locale;
import java.sql.*;
public class casa {
public static Connection con = null;
public static Statement s = null;
public static String sql = null;
public static String mydate = "01.01.2001";
/** Creates a new instance of casa */
public casa() {
public static void main(String[] args) throws SQLException{
try {
DateFormat shortFormat = DateFormat.getDateInstance(DateFormat.SHORT);
Date date = shortFormat.parse(mydate);
//Open Database
con = getConnection();
s = con.createStatement();
sql = "select date1 from table1 where date1 <= '"+date+"'";
ResultSet rs = s.executeQuery(sql);
while(rs.next()){
String aba = rs.getString("datum");
System.out.println("New Datum = "+aba);
} catch (Exception ex ) {
ex.printStackTrace();
closeConnection(s, con);
//Connection
private static Connection getConnection() {
Connection con = null;
String user ="aouzi";
String passe ="aouzi";
String url = "jdbc:db2:EjbTest";
try {
//Datenbanktreiber laden
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
//Verbindung herstellen
con = DriverManager.getConnection(url,user,passe);
}catch(ClassNotFoundException e){
} catch(SQLException e){}
return con;
//close Connection
private static void closeConnection(Statement s, Connection con) {
try {
s.close();
} catch (SQLException e) {}
try {
con.close();
} catch (SQLException e) {}
I'm getting the following errors:
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0180N
The syntax of the representation of a date/time of day value as character sequence is false. .SQLSTATE=22007

I'm pretty sure it won't understand what date.toString() returns. If you know what format the database understands, you do it like this:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yy"); // e.g. 18-Apr-02
String datestring = sdf.parse(date);
and use that instead of date in your sql string. Some databases understands it if you do
"to_date('18-Apr-02')"
so you could include that in your sql string as well..
You could also try to make it a java.sql.Date and hope your jdbc driver knows how to convert it to a string that the database understands if you don't know the format:
con = getConnection();
PreparedStatement ps = con.prepareStatement("select date1 from table1 where date1 <= ?");
ps.setDate(new java.sql.Date(date.getTime()));
ResultSet rs = s.executeQuery(sql);

Problem in java.lang.String.format()

Not sure if this has got anything to do with it, but
the format() method was added to String in Java 5.0.
Maybe you are using an older version in that second
case?You're right. It works when I've changed it from 1.4 (default) to 1.5. Thank you very much.

Convert HH:mm:ss String format.

Hi,
I have a formula in webI to display Milliseconds to HH:mm:ss and is in String format.
Is there a way to convert to date or number format?.
Also, how to calculate average of Max and Min time?.
Thanks,
Jothi

Hi Jyothi,
To take a average time do following-
1) Convert Min Time and Max Time into Seconds.
MaxSec=ToNumber(Substr([MaxTime];1;2))*60*60+ToNumber(Substr([MaxTime];4;2))*60+ToNumber(Substr([MaxTime];7;2))
MinSec=ToNumber(Substr([MinTime];1;2))*60*60+ToNumber(Substr([MinTime];4;2))*60+ToNumber(Substr([MinTime];7;2))
2) calculate approximate Avg seconds-
AvgSec=([MaxSec]+[MinSec])/2
3) Convert AvgSec in to hh:mm:ss.
AvgTime=Floor([AvgSec]/3600 )+":"+Floor(Mod([AvgSec];3600)/60)+":"+Mod(Mod([AvgSec];3600);60)
Hope this help.
Thanks,
Anuj
