How to filter a form with pagination?

Hi all,
I've converted an app to Apex 3.1 (thanks to helpful folks here), but am stuck on the final form. I'd like to streamline the master-detail form, skipping over the tabular report in the detail. Here's (almost) a shell of what I'm trying to do:
[http://apex.oracle.com/pls/otn/f?p=57085|http://apex.oracle.com/pls/otn/f?p=57085]
I'd like the select list in the top region to be able to filter the results in the lower region, showing one row of info at a time in a form. The above example isn't nearly as complex as the real form I'm using, of course, but it should show what I'm trying to do.
I've set up the computation for P1_EMPNO as:
select min(empno)
from "#OWNER#".emp
where deptno like :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL...with a conditional that P1_EMPNO is NULL. Likewise, the row fetch contains the same WHERE clause as above.
I've been running around in circles trying to debug this, prototyping several forms to test combinations of branches, SQL, and such, but no luck.
Has anyone done this before? I see some semi-close threads here, but they seem to end up as a report.
TIA!
Rich

Hi Rich,
Sorry - just seen this.
Yes, I have done something similar before (though the filters were handled on a separate page, the principle would be the same).
The important parts are the selection of the first record, the IDs for the Next and Previous records, the conditional display of the Next/Previous buttons and how to set the current EMPNO id.
1 - As you have a form on the page already, the first record can be set using a Before Header page computation that is conditional on the PK field being null and using your code as the source:
select min(empno)
from "#OWNER#".emp
where deptno like :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL2 - You should then have hidden NEXT and PREVIOUS items on your page. These should be calculated using Before Header computations on EVERY page load (ie not conditional) and using SQL queries:
Previous (say Item name of P1_PREVIOUS_EMPNO):
select NVL(max(empno),0)
from "#OWNER#".EMP
WHERE DEPTNO LIKE :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL
AND EMPNO < :P1_EMPNONext (say Item name of P1_NEXT_EMPNO):
select NVL(min(empno),0)
from "#OWNER#".EMP
WHERE DEPTNO LIKE :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL
AND EMPNO > :P1_EMPNO3 - Your Next button should be conditional on P1_NEXT_EMPNO not being 0 and your Previous button should be conditional on P1_PREVIOUS_EMPNO not being 0
4 - The Next button should trigger a branch that sets the value of P1_EMPNO to P1_NEXT_EMPNO and your Previous button should set P1_EMPNO to P1_PREVIOUS_EMPNO
5 - Your branches triggered by the Filter and Reset buttons should reset P1_EMPNO to null (the computation will calculate this again)
Then, when the page loaded, the first EMPNO that matches the filter is determined and the next/previous EMPNO's are automatically calculated and the buttons shown/hidden as appropriate. Clicking Next or Previous will move through the records and new Next/Previous EMPNO's are calculated each time. When a new filter is applied or the page is reset, the EMPNO is cleared out and recalculated based on the current filter.

Passing values to OnDemandProcess from Select Statement on Reports Page

I think I'm just missing some of the proper syntax, Can somebody please help me.
As I've come to understand this process of passing the values,
I recognize it as (3) steps.
1. Referencing the "javascript" in the Select Statement of the Reports Page.
2. Including the "javascript" in the Page Header region.
3. Defining the Process as an OnDemand Application Process.
My problem is:
a. I can't seem to get the Value passed to the Application Process.
b. I don't know how to reference the Value passed once I get it passed.
Here's what I've got done so far:
1. (The Select Statement)
   onClick="javascript:ORDER_CONNECT_SEQUENCE('||ID||')
{code}
2. (The javascript)
{code}
function ORDER_CONNECT_SEQUENCE('+ID+')
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ORDER_CONNECT_SEQUENCE',0);
get.add('+ID+');
gReturn = get.get('+ID+');
{code}
3. (The Application Process)
{code}
   BEGIN
   Select '+ID+' into THIS_CIRCUIT from dual;
{code}
I Know that the Application Process is being referenced and that the OnClick routine is working properly,
because if I plug a Value into the Application Process, instead of using '+ID+',
Then I get all of my desired results.
Any help you can give me here is greatly appreciated.
Thanks- Gary

Dimitri, Thanks for your efforts here, but its still not working for me.
Here's what I understand from your suggestions:
1. (changes to the javascipt)
   a. replace function ORDER_CONNECT_SEQUENCE('+ID+')
       with
       function ORDER_CONNECT_SEQUENCE(pId)
   b. replace get.add('+ID+')
       with
       get.addParam('x01',pId)
   c. replace getReturn = get.get('+ID+')
      with
      getReturn = get.get()
      get = null2. (chages to the Application Process)
   a. add l_value varchar2(4000) to my list of declarations
   b. add l_value := wwv_flow.g_x01 below the begin statement
   c. I guess then I would reference the l_value like this:
       Select l_value into THIS_CIRCUIT from dual* Also, You didn't mention any changes in my Select statement in the Reports region of the page.
FYI.
onClick="javascript:ORDER_CONNECT_SEQUENCE('||ID||')
{code}
The 'ID' which I'm referencing here is an ID from the table which I'm querying.
Am I misunderstanding you somewhere?
Thanks- gary

How access to Smart Card Readers using Labview?

I´am trying access to Smart Card Readers by Labview, but I have problems.
I want to read SIM card GSM using Labview.!
The file winscard.dll has the functions to access, but I dont have skill with "Using External codes in LabView".
In MSDN library there is the specification about the functions for winscard.dll
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthn/security/smart_card_authentication.asp
When you install a driver for some smart card reader you access to it by winscard.dll.
Att. Enrique

Finally I can acces to the smart card readers (PC/SC) with Labview,   this is the first part where I can establish the context and realease it, and I can get the first name of my list of PC/SC readers that I have connected to my computer.
I was wearing the "Call Library Function" for winscard.dll
For Establish the context you need :
    function name : SCardEstablishContext
Calling conventions : stdcall (WINAPI)
function prototype :    long SCardEstablishContext(long SCARD_SCOPE_USER, long NULL1, long NULL2, unsigned long *hContextHandle);
function name : SCardReleaseContext
Calling conventions : stdcall (WINAPI)
function prototype :  void SCardReleaseContext(unsigned long hContextHandle);

( Urgent ) Date Formatting

I want to know how to get a date value with Milliseconds by using Date Format or any.
For Eg: I am having a LOG( Transactions) table wherein I have a date_create column of a DATE Datatype.
I want to get( Display or retrieve) the value in Milliseconds after formatting. Is there anyway out.
Does ORACLE provide that..
Thanks in Advance for your Response..

2 solutions:
1) write a java stored procedure. java has time functionality
that is much more granular then the Oracle DATE type. This will
work in 8.1.5 and up. It can look like this:
[email protected]> CREATE or replace JAVA SOURCE
2 NAMED "MyTimestamp"
3 AS
4 import java.lang.String;
5 import java.sql.Timestamp;
6
7 public class MyTimestamp
8 {
9 public static String getTimestamp()
10 {
11 return (new
12 Timestamp(System.currentTimeMillis())).toString();
13 }
14 };
15 /
Java created.
[email protected]> create or replace function my_timestamp
return varchar2
2 AS LANGUAGE JAVA
3 NAME 'MyTimestamp.getTimestamp() return java.lang.String';
4 /
Function created.
[email protected]> l
1* select my_timestamp, to_char(sysdate,'yyyy-mm-dd
hh24:mi:ss') from dual
[email protected]> /
MY_TIMESTAMP
TO_CHAR(SYSDATE,'YY
2000-06-22 13:47:53.376
2000-06-22 13:47:53
[email protected]>
2) use an external procedure written in C. C has api's to the
system that allow for much more granular time components. This
will work in 8.0 and up. For example if you run something like:
[email protected]> create or replace library timelib as
2 '/export/home/tkyte/src/t/extproc.so'
3 /
Library created.
[email protected]> create or replace
2 procedure get_extended_time( p_timestring out varchar2 )
3 is external
4 name "get_extended_time"
5 library timelib
6 language C
7 with context
8 parameters ( CONTEXT,
9 p_timestring STRING,
10 p_timestring INDICATOR short,
11 p_timestring MAXLEN int,
12 p_timestring LENGTH int );
13
14 /
Procedure created.
[email protected]> declare
2 l_timestring varchar2(30);
3 begin
4 get_extended_time( l_timestring );
5 dbms_output.put_line(
to_char( sysdate, 'mm/dd/yy hh24:mi:ss' ) );
6 dbms_output.put_line( l_timestring );
7 end;

4503 VTP Domain Name

I have a lab that consists of 2 - 4503 with SUPII running cat4000-i9s-mz.122-25.EWA14.bin as the core devices. I have been practicing for the BCMSN test and was working with the different VTP confiuration options. Here are the two issues that I am having. One of which from reading other posts, I may have answered, but want to verify.
1- 4503 (Core_1) was configured as Server, but no VTP summary advertisements where being propegated to the other clients. I verified the configuration multiple times to ensure accuracy. All VTP Domain names where empty (factory default). Not until I changed the VTP Domain name to Test, did I get propegation of vtp advertisements. I have in the past been able to set up vtp on 3550, 3560 switches with no VTP Domain name and VTP worked as expected. From reading, it appears the non propegation of vtp summary advertisements is the norm for 4503. Can someone verity this.
2- How do you remove the VTP Domain name from the 4503? I was able to remove the name from the other devices, 3550, 3560 by doing the following:
     del flash:vlan.dat
      wr er
      reload
     On the 4503 I did the following:
      Switch#del /r /f cat4000_flash:vlan.dat
      reload
     After reload, everything was back. I also assumed when the 4503 was booting, it may have recieved the VTP information from the other 4503. So I isolated both by disconnecting the uplinks to all other devices. Still no go. I have copied the start-up config to a tftp server, modified the config by removing all vtp information then copied back to running-config and this worked. But it seems like there should be a better (easier) way of getting the vtp domain name removed on a 4503

Hi,
Deleting the vlan.dat from cisco switches will delete the complete vlan and vtp information from database and if you are not able to delete the domain name in these type of situation try configuring the some bogus name with mode as transperent mode so that other should not get impacted.
check out the below link for more information

Regarding download customer.fmb and order.fmb

Hello,
Can you please let me know from where can i download customer.fmb and order.fmb for oracle forms 6i.
Please explain that when do we use set_BLOCK_PROPERTY, i have gone through documents there are few examples and explaination of syntax but still i'm unable to understand when it to be use in menu or forms.
Thanks

Then we need to know what document you are reading so we know what files it references. If the document is a propietary document, you may have to go to the author of the document to get the files. For example, if you are studying from a copy of an Oracle Training book, you will need to contact Oracle to get copies of the sample forms. i got the pdf from internet the name of document is "*Oracle Forms Developer Build Internet Applications 2-Volume 1 Instructor Guide.PDF 40034GC10 Production 1.0 May 2000 M011398*" and here is no link to attach the file so i'm unable to send you that document.
In above document, i'm going through " *Practice 1 and 1 Create a new menu module.*"
some following details are given below:-
1 Create a new menu module.
a Using the following screenshot as a guideline, create a new menu
module called M_SUMMITXX where XX is your student course
number.
here is figure regarding with menu editor, we have to followup to that figure
File Menu and given property of file menu like below but it is in tabular form so i'm unable to copy paste here exactly the same:-
Label_Menu Item_Type Command_Type Menu_Item_Code Visible_in_Menu Visible_in_Horiz._ Menu_Toolbar icon_Filename
Save Plain PL/SQL DO_KEY(’COMMIT_FORM’); Yes Yes Save
Clear Plain PL/SQL DO_KEY(’CLEAR_FORM’); Yes Yes Abort
Null1 Separator Null Yes Yes
Exit Plain PL/SQL DO_KEY(’EXIT_FORM’); Yes Yes Exit
Null2 Separator Null No Yes
like above the all property is given for all menu items and then after some instruction is given like below:-
b Save as M_SUMMIT and compile the menu module.
c Attach the menu module to the ORDERS form.
d Save and compile the form module as ORDGXX where XX is your
student course number.
e Run and test your ORDERS form.
*2* Add pop-up menus to the CUSTOMERS form.
a Open the CUSTOMERS form module. Save as CUSTGXX where
XX is your student course number.
b Copy the EDIT_MENU menu from your M_SUMMIT menu
module to your CUSTOMERS form. Attach this pop-up menu to the
Comments item.
c Save and compile the form module. Deploy your form to the Web to
test.
In this example, the SET_BLOCK_PROPERTY built-in is setting the ORDER_BY property of the S_ORD data block so that records displayed in the block are ordered by the SALES_REP_ID column (block item).
For more information about the SET_BLOCK_PROPERTY search the Forms Help system; click the Index Tab and then type SET_BLOCK_PROPERTY and open the "SET_BLOCK_PROPERTY built-in" topic. As you review this help article it is helpful to have the property pallet open for a data block. Then you can select a property and press F1 to get detailed information about the property.i want to ask that when do we need to use SET_BLOCK_PROPERTY. in which case, because i also read to forms6i.pdf *"Form Builder Reference, Volume 1 Part No: A73074-01"* but i'm unable to understand that how to use and when to use.
there is syntax given only but not given the situation.
NOTE : Please let me know how to attach document then i can send to you, what document currently i'm following or please let me know your mailid so i'll email to you.
Thanks
