Hi all,
I have doubts in interface . You please help me.
My question was
i have two interface. and also i have only one method in both interfaces.these method are same name in both interface
Now i implement these interfaces in my class it's work properly. it doesn't through exceptions.
But i have changed the return type of methods,
ie i put int for one
and void for another one.
it throws exceptions . duplicate method access.
how to i solve this problem? did u catch my point?
please help me Advance in thanks.

Another solution: have the methods take different arguments. Or rename one of them.

How can I have an english interface to labview if the package is in german

Hi ,
I'm a student that makes a project in Germany using labview ... the problem is that my german is not that good , and the labview is in german so here is my question :
how can I have an english interface to labview if the package is in german (labview 7 )
Any help would be apprecieted.

The only way to really have everything in English is to install an English version of LabVIEW. You may want to talk to your local NI sales representative about the possibility of getting a different version.

I have doubt in Read statement

Hi All.
I have doubt in Read statement .i need to convert following select statement as read statement .how can i change help me.
IF p_field1 IS INITIAL
     AND p_field2 IS INITIAL
     AND p_field3 IS INITIAL
     AND p_field4 IS INITIAL
     AND p_field5 IS INITIAL.
    SELECT *
          FROM zdbt
           INTO TABLE itab
           WHERE field5 = p_field5
           ORDER BY PRIMARY KEY.
    IF sy-subrc <> 0.
      MESSAGE s035.
    ENDIF.
ENDIF.
regards,
Jay.

hi
The READ statement is as below:
When u have a table already with values and to improve the performance u need to use this.
Reading Lines of Tables
To read a single line of any table, use the statement:
READ TABLE <itab> <key> <result>.
For the statement to be valid for any kind of table, you must specify the entry using the key and
not the index. You specify the key in the <key> part of the statement. The <result> part can
specify a further processing option for the line that is retrieved.
If the system finds an entry, it sets SY-SUBRC to zero, if not, it takes the value 4, as long as it is
not influenced by one of the possible additions. If the internal table is an index table, SY-TABIX
is set to the index of the line retrieved. If the table has a non-unique key and there are duplicate
entries, the first entry is read.
Thanks

How to find out in program which all classes have implemented an interface

Hello,
I have created an interface and few classes are implementing the interface.
I want to know in a program which all class have implemented the interface.
Is it possible to find it out and how?
Regards,
Bikash.

Hi Bikash,
Read the Database view VSEOIMPLEM with where condition REFCLSNAME = Interface Name and version = 1.
This would give you all the classes which have implemented the interface and are active...
If you want to look at the values that the field version can have then see Type Group SEOC ans search for version....
Hope this help...

Welcome to the Support Commuities. See under Supported Models here:

...Although your MacBook Pro is supported, it may be advisable to wait until OS X 10.8.1 or 10.8.2 in order to avoid the possibility that your Mac slows down due to bugs in 10.8.0.

I have doubt regading...response.sendRedtrect,

Hi,
I have doubt regading...response.sendRedtrect,
That is, it possible to send Session object, one server to another server..using response.sendRedirect.
i would very thankful to give this answer,
Thank you
Ramesh

To my knowledge, response.sendRedirect will be a fresh request. So a new Request object will be created and you will lose all information that you had in your previous request object, including session.

Procedure must have an explicit interface specified

hello all,
i'm facing a problem i don't understand. Here is a piece of code that compiles well with gfortran, but not on sun studio:
program test_fortran
implicit none
interface
     subroutine f1(t)
       double precision, intent(in), dimension(:,:) :: t
     end subroutine f1
     subroutine f2(t)
       double precision, intent(in), dimension(:,:) :: t
     end subroutine f2
     subroutine fct()
     end subroutine fct
end interface
call fct()
end program test_fortran
subroutine f1(t)
double precision, intent(in), dimension(:,:) :: t
print *, 'f1'
end subroutine f1
subroutine f2(t)
double precision, intent(in), dimension(:,:) :: t
print *, 'f2'
end subroutine f2
subroutine fct()
double precision, allocatable, dimension(:,:) :: t
allocate (t(5,5))
call f1(t)
call f2(t)
deallocate(t)
end subroutine fctand f90 (SS12u1) gives me errors:

The Fortran 99, 95, and 2003 standards require a procedure that
has one or more assumed-shape dummy arguments to have
explicit interface in any scoping unit in which it appears. In
your example, the subroutines f1 and f2 have explicit
interface in the main prgram, but they have implicit interface in
the subroutine fct. You need to provide explicit interface for
f1 and f2 in fct. You might want in copy the interface block
that appears in the main program in fct.
Sun Fortran keeps a record of the interfaces of the program units
it encounters. That is why it knows f1 and f2 need to have
explicit interfaces in fct. If you move the text of f1 and f2 so
that they appear after fct, the error message is likely to go away.
The code will be broken, but you will not get an error message.

Want to install Oracle Linux Rel.6 and have a graphical interface

After reading:
Does Oracle Linux Rel.6 have graphical capabilities
How do you install the GUI for Oracle Linux Rel 6?

Dude wrote:
I'm glad you did not take my remark to call you a Linux enthusiast in bad way. It certainly was not meant to be a bad comment, but it's was probably silly of me to make such a remark anyway. I do not take personally offence easily in a forum like this. No, if you want to offend me, post poor code and claim it as the best thing since slice bread. ;-)
I guess I strive to be liberal, but by definition I don't think I really fit into any political wing.Likewise. Find politics a necessary evil to keep abreast of - such as the election in the US.
Back to Linux and your example, I have used such interfaces for many years too. Unfortunately we often have to use what is provided. However, the reason for the text interface is no longer valid, unless your input device is only a text based terminal.Not as much the input device - heck, pure tty devices are pretty much a thing of the past. It is about the complexity of the infrastructure between you and the device you need to administer. And about the task you need to perform.
The connectivity can mean being unable to run a GUI - due to performance, firewalls, router configurations and so on. The task at hand could very well be easily done, using the relevant o/s commands via a command line interface.
I think there is nothing against a GUI app that runs on your PC to sends appropriate commands to a text interface over a slow serial link, apart from the effort that is required to interact with errors, etc.Much more complex than that. A terminal server is usually used - and it attaches to the serial/RS232 connections of multiple devices that need to be administered. It will typically reside on a separate management network too, and not on the local company/corporate intranet.
So for you to access a device to administer, you need an open firewall to the management network to reach the management server that handles the serial console connection for the device you want to administer. You need a valid o/s account on that terminal server. You need to use ssh to access the command line of that terminal server. You need to enter the relevant command that will attach your ssh session to the RS232 console connection to the device to administer.
There is no GUI app on your side that can not only automagically do all this for you, but also provide you with GUI admin widgets to send commands to the remote device. Even if that remote device being sysadmin'ed is Linux, different distros and different versions of the same distros, means different commands, variances in command line parameters for such commands, and so on.
A sysadmin that cannot deal with such situations, and need a GUI as a crutch to administer a device.. I for one will not call that person a sysadmin. I would call the person incompetent instead. Harsh views perhaps, but being sysadmin is an unforgiving job. A mistake, or inability to access a device and fix it using the bare minimum, could result in severe financial loss for the company.

Have doubt?? Can any one clear it

Hi guys i have doubt.It will be nice if
some one clears it
around.
Question:
when making a connection to the database using
ConnectionPooling should we close
connection,statementobject and resultSet.
like this(this is the way i am doing too.)
try
---opening a connection,rs,stmt
other code
}catch() {
finally{
if(rs!=null)
rs.close();
if(stmt!=null)
stmt.close();
if(conn!=null)
conn.close()
Doubt:
Is it not Sufficient to close the connection.Can any one
explain in detail why resultset and statment should be
closed.

From my understanding, close releases resources on the object, so I would suspect that each DB driver implements their resources independently. It would be DB driver specific if closing the connection would cascade the resource cleanup to any objects that were created within that connection. I perform the same logic you do at the end of my DB calls. I have each in a try/catch since close throws SQLException, and I would prefer if each got the chance to execute. I don't do anything with an exception if close fails, because there really isn't anything you can do.
try {
      ...something to DB
}finally
   try {
       if(rs != null )
          rs.close();
   }catch(Exception e){}
   try {
       if(cursor != null )
          cursor.close();
   }catch(Exception e){}
   try {
       if(conn != null )
          conn.close();
   }catch(Exception e){}
}

Does my W500 have an SDIF interface or not?

I am trying to do some high-end audio stuff on my Thinkpad W500, which requires having very low-latency audio, and I'm running into all kinds of strange problems.
Upon the recommendation of several audio forums I installed the ASIO4ALL driver, but oddly it can only see an SDIF interface for my sound card, not the ordinary headphone/speaker jack. Even stranger, there doesn't seem to be an SDIF interface on the machine. Windows thinks the SDIF interface is attached to the "rear panel", but unless it's referring to the HDMI port, I can't find such a thing. I've searched around and while I found a couple of things that might imply some sort of docking station one needs to actually use SDIF, I haven't found anything definite. Can anyone help clear this up for me?
The other issues are less likely to be Lenovo-specific, but if anyone has insight about any of the following I'd also really appreciated it:
Why does ASIO4ALL only see the SDIF interface? Other audio software sees both SDIF and regular speaker interfaces for the sound card (Conexant 20561 SmartAudio)
Why do does some software (e.g. Reaper) give me the option to use the WSAPI driver in exclusive mode, but others (e.g. Maschine) only let me use shared mode, which has higher latency?
Thanks to anyone who can help me out!

Here is http://www.youtube.com/watch?v=3jQQqeZ7_gU a short video of it. Unfortunately its quality is not very good to judge. There are several shots of the display from various angles (1:20 - 1:30, 2:00 - 2:05, 2:57 - 3:01). Moreover 2:27 is a very short shot from top angle where you can find that the white X1 text goes away. Typical sign of TN panel. 3:35 - 3:50 shows detail of Windows taskbar and its contrast does not seem to be very good (for IPS panel).
But again, due to poor quality of the video it is still a speculation.
Thanks for the link. It's incredible to me that members of the press and other journalists haven't asked the simple question of what the screen technology is for the production units. Nevermind none of them have asked if the screen in the video is actually the same screen that will be used in production units.
Meanwhile we get to wait for Lenovo to trickle out information over months...
This is one thing I do like about Apple. When they announce something, it's the entire specification and you can buy it within hours, not months.
