Need Help On Statement.......

I'm currently stuck with this statement:
Container container = getContentPane( );
What is a container ? And what is the function getContainPane? And what is a Pane?
Please help me...................................

That deals with the AWT or Swing.
You have to work with Containers and Components to make a Graphical User Interface.
Containers contain components, and Components are something like a textfield or button.
To arrange components in a special order you have to use LayoutManagers.
getContentPane() is a method to get the pane you can add some components to.
An example:
JFrame f = new JFrame("Title");
Container c = f.getContentPane();
c.setLayout(new BorderLayout());
c.add(new JLabel("Label1"), BorderLayout.SOUTH);
c.add(new JLabel("Label2"), BorderLayout.NORTH);
c.add(new JButton, BorderLayout.CENTER);
Hope it helps

Need help created state machine that is time based

I need help with my labview program. My goal is to write a program that allows the user to turn a toggle button on/off. When they do this it will start a loop witch turns on a digital switch for 45 minutes then off for 30 seconds and on and on till the user toggles the switch off. The timing does not have to be precise. I am using the NI 9476 digital output card.
I have written the code to turn the switch on/off. I know need to add the looped fuction for on 45 minutes/off 30 seconds. I assume the most efficient method would be using a state machine, but I was having trouble figuring it out.
Attached is the program I have written thus far without the loops.
Thanks,
Barrett

I cannot see your code since I don't have 2010 installed. A state machine would be good approach but in order to allow the user to cancel and possibly abort the process at any time your state machine should have a state such as "Check for timeout". In teh loop containing the state machine use a shift register to pass the desired delay value and the start time time for that particular delay. Once the user starts the process set the delay time to your desired time (45 minutes expressed as seconds) and have another shift register that contains the next state to go to after the delay completes. Use a small delay (100ms to 500ms depending on how accurate you want your times to be) to prevent your state machine from free running and then check the delay again. Use the current time and compare it to the start time. If the desired time has passed then go to the next state. You can store the next state in a shift register. No do the same thing for your Off Time state.

Need help in Statement level triggers.

Hi All,
I would like to clarify few things about statement level triggers. here are my doubts,
1. does a statement level trigger have access to the column values of each row that the trigger affects? if so provide me with some examples.
Thanks,
james.

Not by default. If you need to see the column values in an after-statement trigger, you need to use a row-level trigger to accumulate the values in a package variable. This approach would use a before-statement trigger to clear the variable (a table of records based on the rowtype of the table, usually), the after-row trigger to add a row's column values, and then the after-statement trigger to loop through the PL/SQL table (array, collection, etc.) and do whatever is needed.

Need help created state machine with timed digital output

Hello everyone I'm new in LabView especially about how to make a state machine. I want to make simulation about state machine with digital output. In Front Panel there are volt_in as an input slider (0-10 V), two numeric control (upper limit and bottom limit), a waveform chart to plot those 3 value, and three boolean (P0.0, P0.1, P0.2) as an indicator. Boolean indicator will on if input from slider exceed the limit in certain situation. This simulation will work as follow:
1. Define the upper & bottom limit (ex. 8 & 4V)
2. Make an input from slider (0-10V)
3. If input (2) exceed the upper limit but less than 10 second (ex. you have 9V input for 8 second, but after 8 second you change the slider back to normal between 4-8V) then the boolean indicator P0.0 & P0.2 will stay off
4. If input (2) exceed the upper limit more than 10 second (ex. you have 9V input for 4 second, change to 8.5 V for 3 second, and then change to 10V for 3 second) then the boolean indicator P0.0 will turn on for 5 second, turn off, then follow by indicator P0.2 for 5 second, and turn off
5. Wait 15 second, then repeat process from (2)
Same process for input that exceed the bottom limit (P0.1 and P0.2 as indicator).
Can you help me make the block diagram of this process? I will appreciate any of your help.
Best Regards

I would highly recommend you to open the template in LabVIEW to design state machines. You can the Standard State Machine template if you go to File -> New.. and Browse to VI -> From Template -> Frameworks -> Design Patterns.
Also, here is a good explanation of one:

Please wait? I'm sure it says more than that, right?
Have you tried simply saving the PDF (it IS a PDF correct?) to your desktop and opening it from there?
Did you get this form from the IRS or did it come from somewhere else? If the IRS again, what version of Reader?

Hi,
After WHERE .......... is indicates an OUTER Join condition.
In this type of join, system retrieves the data for matched and
as well as unmatched.
Example:
EMP table have a column DEPTNO with the data 10, 20, 30 (total rows=14)
DEPT table have a column DEPTNO with the data 10, 20, 30, 40, 50 (total rows=5)
If the WHERE clause contained EMP.DEPTNO(+) = DEPT.DEPTNO
then the output contain the data relative to 10, 20, 30, 40, 50 (total rows = 16)
i.e. 14 rows (with matching data) and 2 rows (with unmatching data)

Need help with a For loop that uses a Break statement

I need to create a for loop which counts down from 100-50 and divides the number being counted down by a counter. Can anyone help me?
public class Break
public static void main ( String args []) (;
     int total = 0
     int counter = 0
     for { (int number = 100; total >=50; total --)
     if (counter == 0)
     break;
     } // end of for loop
     int output = number/counter
     system.out.printf("The number is" %d output/n)
     }// end of method main
}// end of class Break

Im sorry I didnt explain myself very well i do not need the break statement at all.
I now have this code:
public class BreakTest
   public static void main( String args[] )
      int count; // control variable also used after loop terminates
     for (int i = 100; i >= 50; i = ++count)
   if (i >= 50) {
    continue;
      System.out.printf( "\nBroke out of loop at count = %d\n", count );
   } // end main
} // end class BreakTest
/code]
and i get these error messages:

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Since you are using where condition in loop statement and also using the control break statement thats why it is showing the error for you.
So if you want you can do like this
loop at itab into wa.
if not wa-f1 is initial ....<and other conditions>.
continue.
endif.
at new   f1.
endat.
endloop.
It will resolve your problem but I am having the doubt how the at new will work properly...

Need Help On SQL Statement

I am using Sybase as my back end database. I need help on my SQL statement regarding datetime. The datetime is store as a 9 digit integer in the database (...I believe it is a Decimal(30,6) format, let me know if I am wrong).
If I do this, "select * from mytable;" It works out fine (except I don't know what the date means e.g. 998919534)
If I do this, "select * from mytable where datetime_col < '9/5/2002' ; I got an error. I even tried '9/5/02 11:00 000 am' but it didn't help.
How do I specify a date or datetime in my query?
Thanks in advance.

I execute the sql statement
select * from mytable where datetim_col < convert(datetime, '3/4/2002', 101) ;
I got mix result. I got an error message "cannot convert 10375584 to a date.
Yet, he statistics window of the I-sql says
"estimated 493 rows in query (I/O estimate 87)
PLan> mytable (seq)"
It looks like I my the SQL statement is correct and then the system can't display it in the Data window.
Any thought ?

Need help for sql statement

Hi,
Need help to write sql statement.
create table t_dt ( dt_start date, dt_end date, amount number);
insert into t_dt values('1-Jan-10','10-Feb-10',12);
insert into t_dt values('11-Feb-10','10-Mar-10',10);
insert into t_dt values('11-Mar-10','20-Apr-10',8);
insert into t_dt values('21-Apr-10','28-Jun-10',10);
insert into t_dt values('29-Jun-10','20-Sep-10',10);
insert into t_dt values('21-Sep-10','10-Oct-10',10);
insert into t_dt values('11-Oct-10','31-Dec-10',8);
insert into t_dt values('1-Jan-11','10-Feb-11',8);
insert into t_dt values('11-Feb-11','10-Mar-11',7);
insert into t_dt values('11-Mar-11','20-Apr-11',6);
insert into t_dt values('21-Apr-11','28-Jun-11',6);
insert into t_dt values('29-Jun-11','20-Sep-11',6);
insert into t_dt values('21-Sep-11','10-Oct-11',4);
insert into t_dt values('11-Oct-11','31-Dec-11',8);
Result should be like below..
dt_start     dt_end     Amount
1-Jan-10     10-Feb-10     12
11-Feb-10     10-Mar-10     10
11-Mar-10     20-Apr-10     8
21-Apr-10     10-Oct-10     10
11-Oct-10     10-Feb-11     8
11-Feb-11     10-Mar-11     7
11-Mar-11     20-Sep-11     6
21-Sep-11     10-Oct-11     4
11-Oct-11     31-Dec-11     8
Just to explain the example, take a row with start date as 21-Apr-10 in the above insert statements, since it has the same amount for next two rows (i.e. with start date '29-Jun-10' and '21-Sep-10') these 3 rows should be converted to represent only 1 row in the result and the start date and end date should be changed per the result shown above.
Thanks.

Need help on SQL Statement for UDF

Hi,
as I am not so familiar with SQL statements on currently selected values, I urgently need help.
The scenario looks as follows:
I have defined two UDFs named Subgroup1 and Subgroup2 which represent the subgroups dependent on my article groups. So for example: When the user selects article group "pianos", he only sees the specific subgroups like "new pianos" and "used pianos" in field "Subgroup1". After he has selected one of these specific values, he sees only the specific sub-subgroups in field "Subgroup2", like "used grand pianos".
I have defined UDTs for both UDFs. The UDT for field "Subgroup1" has a UDF called "ArticleGroup" which represents the relation to the article group codes. The UDT for field "Subgroup2" has a UDF called "Subgroup1" which represents the relation to the subgroups one level higher.
The SQL statement for the formatted search in field "Subgroup1" looks as follows:
SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP1] T0 WHERE T0.[U_ArticleGroup] = (SELECT $[OITM.ItmsGrpCod])
It works fine.
However, I cannot find the right statement for the formatted search in field "Subgroup2".
Unfortunately this does NOT WORK:
SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP2] T0 WHERE T0.[U_Subgroup1] = (SELECT $[OITM.U_Subgroup1])
I tried a lot of others that didn't work either.
Then I tried the following one:
SELECT T0.[Name] FROM [dbo].[@B_SUBGROUP2] T0 WHERE T0.[U_Subgroup1] = (SELECT T1.[Code] FROM [dbo].[@B_SUBGROUP1] T1 WHERE T1.[U_ArticleGroup] = (SELECT $[OITM.ItmsGrpCod]))
Unfortunately that only works as long as there is only one specific subgroup1 for the selected article group.
I would be sooooo happy if there is anyone who can tell me the correct statement for my second UDF!
Thanks so much in advance!!!!

Please ignore the "http://" in the above statements - it is certainly not part of my SQL.
Please also ignore the strikes.

Hello Dear,
Use the below queries to get the values:
Item Sub Group on the basis of Item Group
SELECT T0.[Name] FROM [dbo].[@SUBGROUP] T0 WHERE T0.[U_GroupCod] =$[OITM.ItmsGrpCod]
Item Sub Group 1 on the basis of item sub group
SELECT T0.[Name] FROM [dbo].[@SUBGROUP1] T0 WHERE T0.[U_SubGrpCod]=(SELECT T0.[Code] FROM [dbo].[@SUBGROUP] T0 WHERE T0.[Name] =$[OITM.U_ItmsSubgrp])
Sub group 2 on the basis of sub group 1
SELECT T0.[Name] FROM [dbo].[@SUBGROUP2] T0 WHERE T0.[U_SubGrpCod1]=(SELECT T0.[Code] FROM [dbo].[@SUBGROUP1] T0 WHERE T0.[Name] =$[OITM.U_ItmsSubgrp1])
this will help you.

Getting a box that states: can't find
adobe pdf resource files... need help!!!

I get a similar error, but only under the following conditions: I must be printing to the Adobe PDF printer and printing multiple pages, one at a time, and then it only happens on the second and subsequent print attempts. That is to say, the first page prints just fine and this just started yesterday afternoon. The specific file referenced in the error does not exist, but why would it work the first time and not the second? Since it only started yesterday, I tried uninstalling and reinstalling this morning, but it made no difference. I don't see anything under print properties like job-options and it is a single user, unshared printer. Thoughts? I understand the same thing is happening in at least one other of our locations, but no one there has looked into it yet. This is a BIG problem for me, however, and I need to find an answer quickly.
