TableView editableCell containing dates
I have a tableview to keep simple records. It has three columns containing cells with only the channels, one that contains cells with bed Double and the other with cells containing Dates.I have created three separate cell plants and cell classes and can correctly sort the string column and twice in the right order.
If I only use cells of String to contain the dates of the sort order is based only on the actual string and not the date.
I thought it would just a SimpleDateFormatter to format the Date cell, but if I try this I get a compiler error saying that it cannot format the object in the cell as a date.
No idea what's wrong with my code.
It's the record class
package tabletrial;
// @author David
import javafx.beans.property.SimpleDoubleProperty;
import javafx.beans.property.SimpleStringProperty;
public class Record {
public final SimpleStringProperty description;
public final SimpleDoubleProperty amount;
public final SimpleStringProperty date;
public Record(String desc, Double amt, String dte) {
this.description = new SimpleStringProperty(desc);
this.amount = new SimpleDoubleProperty(amt);
this.date = new SimpleStringProperty(dte);
}
public String getDescription() {
return description.get();
}
public void setDescription(String desc) {
description.set(desc);
}
public SimpleStringProperty descriptionProperty() {
return description;
}
public Double getAmount() {
return amount.get();
}
public void setAmount(Double amt) {
amount.set(amt);
}
public SimpleDoubleProperty amountProperty() {
return amount;
}
public String getDate() {
return date.get();
}
public void setDate(String dte) {
date.set(dte);
}
public SimpleStringProperty dateProperty() {
return date;
}
}
It is observableArray that contains the initial records// create initial records
private static final ObservableList<Record> data = FXCollections.observableArrayList(
new Record ("Item one",23.05,"11/11/2012"),
new Record ("Item two",2.05,"01/09/1953")
);
This is the problem code I have for the EditableDateCellpackage tabletrial;
import java.text.SimpleDateFormat;

@Override

} else if (t.getCode() == KeyCode.ESCAPE) {
cancelEdit();
}
}
});
this.setGraphic(textField);
}
private String getString() {
return getItem() == null ? "" : df.format(getItem()).toString();
}
}
Thank you
Next time, send the trace message and real stack error.
private String getString() {
return getItem() == null ? "" : df.format(getItem()).toString();
}
format() method accepts a Date and returns a string.
You probably want to use the here, parse() method which accepts a string and returns a Date.

ORA-03297: file contains data beyond the requested value of RESIZING
Hi all
I am trying to increase the size of my space of system tables. The tablespace contains a data size 900MB file and it may increase to 2 GB.
I would like to change this to autoextend I'll operate on the database csscan.
When to change the autoextend and unlimited file I get: ORA-03297: file contains data beyond the requested value of RESIZING
I also tried to increase the data file of 4 GB, but still the same. I see that there is more then enough space on the file system.
Need help.

The autoextend (second statement) should be fine as is.

Extract the lowest members (entity) which contain data
Hello
I am facing a dilemma (obviously).
Report in Essbase (9.3) Script Editor I'm supposed to write an export script that is supposed to select members (entity) lowest that contain data.
Someone knows some way to do this?
Appreciate the advice.I think you ask members of level zero and you want to remove all members that have not given.
The report sample script that I have provided above is there for that. And the alternative that is too large is Cameron dataexport. Anyway you will give members at zero level and those with data. I don't think that you need more research.
(And again, some of us know what documents are and are not approaching the age of retirement quite yet)

How can I determine which text fields contain data?
Although it is a sad testament to my programming skills, I'm little embarrassed because I'm only doing this sort of thing maybe once every two or three years. I am using FormCalc (mainly b/c I'm still learning Javascript and this form had already been written in FormCalc).
Here's the problem:
I have three text fields (Textfield1, Textfield2, Textfield3).
I created three variables (var1, var2, var3) and initialized to 0.
To determine how many fields containing data, I used the if/then/else statements:
If (Textfield1.rawValue == "") then
var1 = 0
on the other
var1 = 1
endif
Textfield2 and Textfield3 have similar statements (respectively using var3 and var2 variables).
To test the code, I have a message box returns the sum of var1 + var2 and var3. With NOTHING entered into all fields of text, I expect him back a sum of 0, but it returns the sum of 3! If I enter data in only one or two of the fields, yet once it returns a value of 3.
I tried the initialization of the value of the Textfields (Textfield1.rawValue = ""), but I always get a value of 3.
This is probably a simple programming error, but still, I'm not a developer. Any help would be appreciated.
I think that you may need to modify your code for: (replace the "with the null value). Change of FormCalc to Javascript
If (Textfield1.rawValue == null) then
var1 = 0
on the other
var1 = 1
endif

You know, in your code curr_rec is not slider.
You cannot use curr_rec % rowcount
If you want to get the number of lines of your loop, then use an additional variableTry this please
declare countLoop NUMBER :=0; begin for curr_rec in( select * from dual) loop countloop := countloop + 1; end loop; dbms_output.put_line(countloop); end;
or
DECLARE CURSOR csr_org IS SELECT empno, ename FROM emp; num_total_rows NUMBER; BEGIN FOR idx IN csr_org LOOP dbms_output.put_line(idx.empno||' '||idx.ename); num_total_rows := csr_org%ROWCOUNT; END LOOP; IF num_total_rows > 0 THEN dbms_output.new_line; dbms_output.put_line('Total Organizations = '||to_char(num_total_rows)); END IF; END; /

Two tables belonged to applications contain data, but the data should be in tables belonged to
Run adadmin, "validate the APPS schema. Examine the output file APPS.lst. See two tables belonging to APPS should be owned by APPLSYS: JAVA 1) $CLASSE MD5$ $TABLE 2) CREATE$ JAVA$ LOB$ TABLE. The report indicates that he must remove the tables belonging to applications. However, only the tables belonging to applications contain data. Arrays owned APPLSYS containing no data.

If you're on 11i, you should find three tables for the first object (under ORDSYS, APPLSYS and ODM schemas). And four tables for the second object (under SYS, ORDSYS, APPLSYS and ODM schemas). You should find a synonym for the two APPS schema objects.

How can I add cells containing data (text) by column
In my spreadsheet, I had a column that contains a product title. I want to add cells containing a title down on my worksheet. What formula to use for this?
Please note: some cells are empty.
Hi suus,
The COUNTA function is your friend
This table has a header row and footer line.
Formula in cell B8 footer = COUNTA (B)
From the browser to the function:
The COUNTA function returns the number of arguments that are not empty.
An invisible character such as a space is considered to be "not empty".

Buffer series VISA not containing data not received all
Hello
I get the competition of the transmitttet of the LGRTest.txt file for my port com3 (9600n81) every second.
Using 'VISA on event Wait function' I was supossed to read the summary after detection of a character of 0xA.
But I get only at random parts of the 486bytes transmittet.
In earlier versions of my code, he did receive the prize. But I discovered that it was old data stored in the buffer.
Then I added "VISA Flush function" before wait as the chariot of the end and then I got the first problem I designed.
Concerning
Morten Skov
The event to wait for the VISA is pending for ANY character to receive. So if you check the number of bytes in the port when half of the message has been sent, you will only read half of the message.
If you actually use the stop character, don't bother with the VISA events. Just a reading VISA with the number of bytes to read the value something rediculously high. Read full when it detects the stop character.

Check that a string contains data only numbers
Hello
I'm trying to find an elegant way to test an input string "serial number" format A00000000 (where A can be any letter and 0 can be a number any). My first thought was to check the following features:
(1) total string length = 9.
(2) using the "Decimal String to the Number.vi", result = 0 (which indicates that the string contains no numbers).
(3) using the 'Decimal string to Number.vi' with an offset of 1, the result is a number.
Unfortunately, that does not differentiate between the following strings:
A00005123 valid
Invalid A5123
Invalid A5123B123
Invalid A005123BC
All the world is this recently? Is there a way to analyze non-specific chips (for example separating the groups of letters, numbers or other?) Is there a complete way to do this without breaking the chain in 9 individual items and do a comparison of 26 item for the letter and 10 element for each number comparisons?
Thank you
Sean

Can I create a recovery disc in a drive that already contains data?
I went through this link "http://windows.microsoft.com/en-in/windows-8/create-usb-recovery-drive".
It is said that when I create the recovery USB drive, old data in USB will be removed is even a hard drive?
Can I create the recovery drive into a USB port and which copy to hard drive and use the HDD when necessary for recovery?
Please help me to understand the working of recovery mechanism in Windows 8.
Thank you

Hello
Yes that is right that the recovery disk is created on a sterile USB drive. Do not put any other data after the creation of the disc of recovery in this matter, otherwise it can not work properly.

dataObject.bitMapData = bitMapData;
dataObject.XPos = xPos;
dataObject.YPos = yPos;
dataObject.spriteName = graphic.name;
Returns the dataObject object;
}
So I thought to it. Paths use BeforeDraw() and EndDraw(), making the filling operations and outline Draw(). The problem is that these functions not called until the path is rendered on the canvas. So, I expanded my class path and too rolled the EndDraw() function. In this function, I sent an event. Then, when I catch the event I can get the DisplayObject of the track (which is now filled) and pass this object in BitmapData().
