How to use a structure at run time....

Hi gurus,
I am confused on how to use the structure in our report..why do we need it...Please help me with that...
Thanks
Cheers:Jim

Or you could simply use a structure in your program to group like fields together. So that you could maybe clear them all at one shot.
For example, say that you have a structure with fields a - z.
data: begin of structure,
        fielda type c,
        fieldb type c,
        fieldc type c,
        fieldz type c,
        end of structure.
So in your program, it is now important for you to clear these fields, if you would have defined them one by one without the structure, you would have to list them all in your CLEAR statement, but instead, since you have them in a structure, you can some say....   CLEAR STRUCTURE.

How to Use Table name at run time

Hi All
I have created a function that accepts a table name as a parameter and returns the maximam sequence number, but in my function body i can not write the parameter name as a table i.e.
CREATE OR REPLACE FUNCTION MAX_ID(TAB_NAME Varchar)
RETURN Number IS
max_id Number;
CURSOR curSalPoint IS
     SELECT MAX(EMP_NUMBER)
     FROM TAB_NAME ;
BEGIN
max_id:=0;
OPEN curSalPoint ;
     FETCH curSalPoint INTO max_id;
     CLOSE curSalPoint;
RETURN max_id
END
But it will give an error saying
(1):PL/SQL: ORA-00942: table or view does not exist
for "TAB_NAME"
Any help would be appreciate ........

Yes, as i contcatinated table name with the original statement, so you can also continate fields' names with your statment and execute immediate the statement.
Sorry i forgot this statement in my function, to execute the statement you need to include following statement
CREATE OR REPLACE FUNCTION MAX_ID(TAB_NAME Varchar)
RETURN Number IS
max_id Number;
query varchar2(200);
BEGIN
max_id:=0;
query:=null;
query := query || 'select max(empno) into max_id from'|| tab_name;
EXECUTE IMMEDIATE query;
RETURN max_id;
END;

Hello,
Using dynamic sql you can pass column name to function. well I am not getting what you really want to do ? Please write in more detail. By the way I am providing one example here. see it uses dynamic sql.
Create or replace function fun_updtest (p_columnname_varchar2 in varchar2,
p_value_number in number)
return number is
v_stmt varchar2(500);
begin
v_stmt := 'update emp
set '||p_columnname_varchar2||' = '||to_char(p_value_number)||'
where empno = 7369';
execute immediate v_stmt;
return 0;
commit;
end;
call to this function can be like this..
declare
v_number number;
begin
v_number := fun_updtest('SAL',5000);
end;

How to use event structure of event data nodes event filter nodes in programming

hi,
I need manual of how to use 'event structure' events of 'event data nodes' and 'event data filters'...please help me....
Regards
Ravindranath

I'm not really sure what you are looking for here. Did you do a search in the LabVIEW help for Event Structure?
The Event Data Node just returns information about the event, like control data, control reference, what caused the event, etc.
The Event Data Filters are just used in Filter Events. This allows you to discard an event or change the data that the event will recieve.

How to dynamically validate users at run time using connection pools ?

Hi Folks
We are facing a peculiar situation . We have established connection to our
oracle 8i database using Oracle Thin driver using conenction pooling at the weblogic
server . We set up connection pools at the console to set up connections to thge
oracle 8i database. However the user name and password is always static when
we create the connection pool at the console .
How do i dynamically validate other users using the same connection pool ??
Eg - The connection pool at design time in the console uses user A and password
- passA . Now at run time lets say I prompt the user for a login screen and want
to trap the user id and apssword parameters entered by the user and use it with
the connection pool created earlier . I tried using the below code snippet :-
Properties props = new Properties();
props.put("connectionPoolID", "Oracle_Thin_Driver_Pool");
props.put("user" , userId );
props.put("password",userPass);
myDriver = (Driver) Class.forName("weblogic.jdbc.pool.Driver").newInstance();
conn = myDriver.connect("jdbc:weblogic:pool", props);
But always it connects to the database using the userid and password set in the
console while creating the connection pool . So how i get the connection pool
to validate my current userid and password entered through the login screen ??
Thanks in advance

Hey Bob.
So I assume you're -completely- working with built executables? You're not going to work in the editor environment to modify your projects at all?
If this is the case, then having a generic deployment phase at the beginning of the executable (with a "setting up hardware for your app" splash screen) isn't a bad idea -
Check the binary on the target, ensure it matches the binary you have on the host machine (in case you ever decide to update).
If they don't match, FTP the new file down to replace the old one.
FTP the ni-rt.ini file, ensure the startup exe is enabled and is pointing to the correct location.
If it's not enabled or not pointing to the correct startup file, modify the .INI file and FTP back to the target.
If you had to update the INI file, ask target to reboot itself. Wait 30 seconds, and wait for target to become available again.
Connect to the target. If you cannot connect, reboot target. If the target comes back and you still cannot connect to the app, notify user.
That's almost exactly how we handle installation and deployment via MAX.
The big assumption here is that the built executables were all built with the same version of LabVIEW Real-Time. If not, you'd need a system replication step in there to make sure the proper version of LabVIEW is on the target before launching the built .rtexe.

How to determine itab type at run time

I need to write a subroutine that organizes data in internal tables for presentation by a smartform. There are a few similarly structured internal tables all with the same field name ("recipe_type") by which the data is sorted. My problem is that how I can determine the type of the itab inside my subroutine at run time? Is it ever possible in ABAP?
The subroutine code is attached below. Thanks for any help.

ENDLOOP.
ENDFORM.                    "beautify_itab

The following code does what I want, but only if the input itab structure is declared first in the program. It won't work if the itab is declared as itab_in TYPE TABLE OF sflight. This is because the function 'GET_COMPONENTS_LIST' only can load the structure of a field declared explicitly in the program. Does anybody know of any method to load the structure of an itab based off a dtab?
Thanks you guys for answers. Points have been rewarded.

How to choose RT System at Run Time

Variations of this question have been asked, but I'm not sure if they've been answered.
We use LabVIEW RT to do a variety of behavior tests. We have multiple experimenters using the same hardware, and each has his/her own set of "What I want to do" requirements.
Originally, we used LabVIEW 7.0 (i.e. Before Project) to develop a Host and Remote (PXI) application. The Host application was built as an .EXE, while the Remote was saved as an .LLB, copied to the PXI, and "invoked" at Run Time by calls to VI Server. Note that this means that the code on the Remote might (is?) not be as compact, efficient, or optimized as if we had built an .EXE. But we definitely can have Bob's Experiment, Jane's Experiment, and Joe's Experiment on the PC (as separate executables), and each could respectively call Bob's RT, Jane's RT, or Joe's RT on the PXI at run time. No need to have LabVIEW (or LabVIEW expertise) on this system, and Bob, Jane, and Joe can be "ordinary users".
"Modern LabVIEW" takes a slightly different (and probably better) view towards Real-Time -- both the Host and Remote programs are built as Executables (the RT is built as an .RTEXE). We can "pre-deploy" the RT code to the PXI, and set it to run at Startup. This makes getting the RT side "running" semi-automatic -- all you need to do (if it isn't running) is reboot the PXI.
But what if you want Bob, Jane, and Joe's version, selectable by running (on the Host) Bob, Jane, or Joe's Host application?
I'm playing with the following algorithm, which seems to work. I'm presenting it here to get feedback, especially if there is a "better way" to do this.
The key to this method is that there is an .INI file on the Remote, C:\ni-rt.ini, that contains, among other things, the RT Target's Startup Application path (by default, this is C:\ni-rt\startup\startup.rtexe).
Consider three Projects, Project Bob, Project Jane, and Project Joe. Within each Project, a Host executable is built having a name like "UI Bob" (or "Jane" or "Joe"), while the Target executable is given the name "RT Bob" (or "Jane" or "Joe"). The three .RTEXE files are copied to the Target and placed in the Startup folder, C:\ni-rt\startup.
Now run one of the Host executables. It does the following:
FTP a copy of C:\ni-rt.ini from the Target to itself.
Get the name of the Startup .RTEXE.
If it is the "appropriate" name (i.e. if the Host program is UI Bob.exe, the Remote should be RT Bob.rtexe), do nothing, as the Target is already running the right code.
Otherwise, we need to force the Target to run the correct Target code. We can do this by changing the Startup entry in the .INI file to the Remote code we need (for example, RT Bob.rtexe), then tell the Remote to Reboot. When it comes back, it will be running the appropriate RT code.
The Host now goes ahead and tries to connect to the Remote. If a connection cannot be established (for example, the Remote code might have stopped), a Reboot of the Remote might fix things up.
Short of trying to write a single enormous program that encompasses every experimental scenario and situation (i.e. have a big Case Statement with a Bob, Jane, or Joe "choice", and a single executable that had everyone's code in it), this seemed to be a fairly simple way to have the robustness of compiled executables on both the Host and Remote machines, yet maintain the flexibility to let the (non-LabVIEW-guru) User choose which executable to run.
I haven't fully deployed this system -- I'm currently at "Proof-of-Concept" stage, but I've got the various "pieces" working. Does this seem like a sensible appropach? Are there other, simpler, ways to accomplish this?
Bob Schor

Hey Bob.
So I assume you're -completely- working with built executables? You're not going to work in the editor environment to modify your projects at all?

Hello Asad,
It is possible to maximize the run time previewer when calling reports from forms. U need to set a parameter named 'MAXIMIZE' to do that.
I m attaching a code sample for u. This is working in my production environment.
DECLARE
pl_id ParamList;
BEGIN
     pl_id := Get_Parameter_List('setProposal');
     IF NOT Id_Null(pl_id) THEN
          Destroy_Parameter_List( pl_id );
     END IF;
     pl_id := Create_Parameter_List('setProposal');
// This parameter is set to hide parameter form at run time
     Add_Parameter(pl_id, 'PARAMFORM', TEXT_PARAMETER, 'NO');
// This parameter is used to maximize previewer window at run // time
     Add_Parameter(pl_id, 'MAXIMIZE', TEXT_PARAMETER, 'YES');
Run_Product(REPORTS, 'sample.rep', SYNCHRONOUS, RUNTIME,
FILESYSTEM, pl_id, NULL);
END;
Feel free to contact me if u need anymore assistance.
Take care and bye

How to change the skin at run time

I am using jDeveloper 11.1.1.3 for ADF.
My UseCase: i want to give a dropdown for skins. User should be able to select the skin at run time and it should be loaded. Please let me know how can i achieve it.
Zee

As per usecase, looks like you have the LOV containing the different skins.
You can ensure that the application is skinned according to the selected value in the LOV.
Ensure that you have a session scope variable that is set, whenever you change the LOV.
For more details, look into this link http://download.oracle.com/docs/cd/E14571_01/web.1111/e10140/skinning.htm
Thanks for your reply, but then...... what will be the skin loaded by default before the user selects the skin - drop down. Do i have to set something default before hand .?Define the LOV such that there are no empty elements. i.e the first element in the LOV is selected.
In the Managed bean, if the session scope is not set, return the skin family for the first element. This would be the scenario when the application loads.
Thanks,
Navaneeth

How to find working workingDirectory on run time

How can I see my working Direcftory at run time.

Are you trying to get the working directory on the server side or the client side?
As Fabrizio mentioned, you can use WebUtil, but this would return the client side information. To obtain the server side details, you can use imported java. Fortunately, because the server side jvm already has everything you need to do this, there is no need to know how to code in java. Refer to the Forms Java Importer documentation for details:
http://www.oracle.com/webapps/online-help/forms/10g/topics/java_importer/c_javaimporter.html
All you need to do is import the following java packages into your form:
java.lang.System
java.lang.Exception
Then add some pl/sql similar to this to your form:
PROCEDURE java_call IS
     jo     ora_java.jobject;
     rv     ora_java.jobject;
     ex     ora_java.jobject;
Begin
-- Get server side working directory.
-- This is the same value which is set in formsweb.cfg
     MESSAGE (SYSTEM.getProperty('user.dir'));
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
          message('Unable to call out to Java, ' || ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
          ex := ORA_JAVA.LAST_EXCEPTION;
          message (Exception_.toString(ex));
END;Once imported, you will have easy access to a variety of server side (Java) properties which can return valuable information. Refer to the following:
