URGENT: Calling Pro C from Forms

Hi All,
How to call a Pro C function from forms?
Can i call a function declared inside a DLL or i can only call a Pro C executable?
Where can i look for more information?
TIA
Naveen

Naveen
If you are trying to call a user exit written in PRO*C ( I assume ur OS is Windows since u re talking about DLL) then yes you can make a dll then likn this dll and call it from ur forms using user_exit. Refer Forms help
But If you wanna call a pure Pro*c program then call the executable ( nothing but a compiled C program) using probably host command
Cheers

CALLING A REPORT FROM FORMS (PROBLEM)

MY PROBLEM IS THE NEXT:
I CREATED A MASTER-DETAIL REPORT CALLING 'ASUNTOS'WITH THE NEXT QUERY:
SELECT ABOGADOS.APELLIDO_P,ABOGADOS.APELLIDO_M,ABOGADOS.NOMBRES,
ASUNTOS.EXP_INT,ASUNTOS.MATERIA,ASUNTOS.GERENCIA,
ASUNTOS.EMPRESA,ASUNTOS.RECLAMA,ASUNTOS.PESOS,
ASUNTOS.DOLARES
FROM ABOGADOS,ASUNTOS
WHERE ABOGADOS.FICHA = ASUNTOS.F_ABOG
AND ASUNTOS.F_ABOG = :ABOGADO ;
-- ABOGADO = PARAMETER.
THIS REPORT WORKS FINE THE PROBLEM IS WHEN I TRY CALL THIS REPORT FROM FORM I'VE USE A BUTTON(WHEN_BUTTON_PRESSED) WITH THE NEXT CODE:
DECLARE
LISTA PARAMLIST := GET_PARAMETER_LIST('ABOG');
BEGIN
IF ID_NULL(LISTA) THEN
LISTA := CREATE_PARAMETER_LIST('ABOG');
ADD_PARAMETER(LISTA,'DESTYPE',TEXT_PARAMETER,'PRINTER');
ADD_PARAMETER(LISTA,'DESNAME',TEXT_PARAMETER,'LPT2');
ADD_PARAMETER(LISTA,'ABOGADO',TEXT_PARAMETER,TO_CHAR(:ASUNTOS.F_ABOG));
-- ADD_PARAMETER(LISTA,'PARAMFORM',TEXT_PARAMETER,'YES');
END IF;
RUN_PRODUCT(REPORTS,'ASUNTOS',SYNCHRONOUS,RUNTIME,FILESYSTEM,LISTA,NULL);
END;
BUT THE REPORT NOTHING DISPLAY.
THERE ARE SOMETHING WRONG WITH THE CODE IN THE BUTTON

Roberto,
Does your report work when it is not called from Forms?
try the following:
[TOOLS_HOME]\BIN\RWRUN60 module=ASUNTOS destype=screen userid=<username>/<password>@<tns> ABOGADO=<some_valid_code>
where TOOLS_HOME is the directory where Reports is installed.
I can see nothing wrong with your code.
Maybe some error in the query?
Also, I would check for the existence of multiple ASUNTOS report definitions. Maybe Forms is calling an older one.
Hope this helps,

Calling a report from forms with a paramter form

Hello,
How do you call a report from forms and get it to display the parameter form. Where you can then call the report using this parameter form. I have been using paramform=yes. but it simply runs the form.
I saw on a a thread ages ago that this was a sample of this available for download. Is this true?
thanks

Here is my code sorry about posting twice. Please note that the parameter list has been created as described.
report_id := find_report_object('MENU_REPORT_NODE');
Tool_Env.Getvar('ReportsServer', reports_server);
Tool_Env.Getvar('ReportsFolder', reports_folder);
dest_file := reports_folder || :global.username || '\' || rep_name || '.pdf';
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_FILENAME, rep_name);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_SERVER, reports_server);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_COMM_MODE, SYNCHRONOUS); -- wait for the report to finish
-- SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_DESNAME, dest_file);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_DESTYPE, cache);
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_DESFORMAT, 'PDF');
SET_REPORT_OBJECT_PROPERTY(report_id, REPORT_OTHER, 'paramform=yes' || ' ' || 'mode=bitmap');
report_job := run_report_object(report_id);

Calling SQL*Loader from Forms

Hi,
I was wondering if anyone has called SQL*Loader from Forms?
What I am wanting to do is use Oracle Forms as the interface where you can specify a file that you can import into the database and it will use a set control file. Push the import button and SQL*Loader does the rest.
Is using Java code to call SQL*Loader from Forms a viable option, or is there an easier way to achieve the desired outcome.
Any ideas or guidance will be much appreciated.
Thanks,
Scott.

Scott,
In forms, there's a HOST built-in command which is supposed to execute any o/s commands.
What you have to do is :
1. Bult up the string exacltly in the fashion which you will run in o/s
2. Call the HOST Built-in and pass in the string
Here's a example :
Declare
lOsCmd Varchar2(1000) := Null;
Begin
lOsCmd := 'sqlldr user-id=userid/passwd@connectStr '
|| ' control=c:\temp\abc.ctl log=c:\temp\abc.log '
|| ' bad = c:\temp\abc.log';
Host (lOsCmd, No_Screen);
End;

Calling an EXE from Forms 4.5

How do i call a windows Exe from forms. Whats the exact syntax to do that? Code sample would help.
Thanks!

Client/server mode calling an EXE from Forms 4.5
The following is a Foreign Function Interface that I employed to launch an outside program in its own asynchronous window. It was a great alternative to the HOST command.
The disadvantage to the HOST command was that the launched program would have to be closed before you could return to the form. With this method the the launched program
could be minimized etc. and you could switch back and forth between forms and it.

Call Stored Procedure from Forms 6i -- Urgent Plz...

Dear All,
I am first writing a stored procedure as:-
CREATE OR REPLACE FUNCTION
good_hire
(birthdate_in IN DATE,
reqsal_in IN NUMBER)
RETURN BOOLEAN
IS
too_young BOOLEAN :=
ADD_MONTHS
(SYSDATE, -216) >
birthdate_in;
too_expensive BOOLEAN :=
reqsal_in > fin.dept_bal;
BEGIN
RETURN NOT (too_young
OR too_expensive);
END;
Now in my forms also i have the same function,which i defined in in my program unit i.e., with the same name good_hire,but with different parameters.
If I want to call this stored procedure(good_hire)in my form
I am writing this code in the pre-Insert trigger.
IF good_hire
(:newemp.birthdate,
:newemp.proposed_sal)
THEN
SELECT empseq.NEXTVAL
INTO :newemp.empno
FROM dual;
ELSE
RAISE FORM_TRIGGER_FAILURE;
END IF;
Notice that i am sending bind variables from my form to the
stored procedure. Now my question :
1) Can i pass bind variables to the stored procedures from
forms or is there any other way i can access the
stored roceures from forms(Expecting a detailed answer) and
from which triggers can I access the stored procedures(like pre-
Insert here)?
2) If at all I have the same parameters in my program unit
function and with the same name good_hire, I know that the code
in the pre-Insert trigger will call only the function in my
program unit and not the stored procedure, but if I like to
call my stored procedure instead of the local function good_hire
then what should I do?
2)As I said before if i have different parameters, for the
stored procedure good_hire and local function good_hire and If
I call good_hire from my pre-insert trigger .. Is it that the
Forms will decide and call the Local function or stored
procedure depending on the parameter list?
I hope all my points are very clear.
I am expecting the best and detailed answer for my
Queries, I also hope these Quests will clear the doubts of many
members in our esteemed group.
Thnx in Advance...
Regards
siree....

Dear Siree,
Oh!! how many Questions? Each how much big??
Ok First of all the answer to your first question.
You can use the Stored procedures in the same way as the Forms procedures. You can pass bind variables to the stored procedures as well. You can also use the stored procedures in any triggers, I think there are no restrictions for that. The only thing is you should be connected to database while compiling the trigger where you are calling the stored procedure.
Answer to your second question.
You cannot direct Forms (I don't know about version 10g), untill 9i, you cannot tell forms to take the stored procedure and leave the local procedure. It will always take the local procedure, once a procedure is called. If not found locally then only it will go for the Stored procedures.
For your third question.
As I told you b4 forms searches for the procedure being called locally first, if locally present, does not go to the stored procedure. If declared by different paramaters in the stored procedure and it is called, then it will throw error (as it first searches for the name locally and if found will take up the one present locally and since that procedure is with different parameter, will throw up error). It is after all a stupid machine and can't think like us.

Call Oracle Reports from Forms ver 9i or 10g

Hi,
Can somebody guide me, how to call Oracle Reports from the Oracle form 9i,
Run_product is no more available into 9i & 10g, Run_report_object is not working with out put type "Screen" or "preview".
What is the best way to call the reports from the form ??? pls help...
Thanks in avdance.
Jitesh ([email protected])

You can use RUN_REPORT_OBJECT with CACHE type, and WEB.SHOW_DOCUMENT to view the document on the screen.
In the Forms help you should find examples.
If you have access to Metalink, have a look at Note:207396.1.

Calling a report from forms

Hello
i have a problem with calling a report from a form.
i use the following statement in the when-button-pressed trigger:
Run_Product(REPORTS, report.rdf',ASYNCHRONOUS, RUNTIME,FILESYSTEM, '', null);
in the reports background engine i get the error
REP-0110: Unable to open file 'report.rdf'.
REP-1070: Error while opening or saving a document.
REP-0110: Unable to open file 'report.rdf'.
End report report [Mon Nov 25 12:30:40 2002].
the file report.rdf is in the same folder as the form calling it
where is the problem
thanks
Marjan

Hi Marjan,
The problem seems to be that the report is not in a directory
listed in the reports60_path. Add the directory into your reports60_path
and check if it solves the problem.

Calling web service from forms..

Forms Gurus,
I am using this demo to call the webservice in Forms.
http://www.oracle.com/technology/obe/obe_as_10g/deploy/callws_fromforms/forms_webservice.htm#r1
I am using a simple button to call get the conversion rate from the web service.
But my code is not doing anything. I used some insert statements to see where my code is failing and is as follows:
DECLARE
jo ora_java.jobject;
rv ora_java.jobject;
EX ora_java.jobject;
v_num NUMBER;
BEGIN
INSERT INTO XXIPAY_WEB_TMP VALUES (111,'before',20);

INSERT INTO XXIPAY_WEB_TMP VALUES (111,'between',20);
commit;
rv:= CurrencyExchangeServiceStub.getRate(jo,'USA','great britain');
INSERT INTO XXIPAY_WEB_TMP VALUES (111,'after',20);
commit;
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
fnd_message.set_string('Unable to call out to Java, '||ORA_JAVA.LAST_ERROR);
fnd_message.show;
     INSERT INTO XXIPAY_WEB_TMP VALUES (111,'java_error',20);
     commit;
WHEN ORA_JAVA.EXCEPTION_THROWN then
     EX:=ORA_JAVA.LAST_EXCEPTION;
     message(Exception_.toString(EX));
     INSERT INTO XXIPAY_WEB_TMP VALUES (111,'exception',20);
     commit;
END;
After pushing the button I am getting the following values from the table:
111 before 20
111 java_error 20
I am importing currencyexchangestub.class, java.lang.Float.class and java.lang.Exception.class.
My code is failing before executing the new function.
Where am I doing wrong? Any help is highly appreciated.
Thanks in advance.
Fubu

Hey Francois,
Everything went fine according to demo until I clicked on the button to get the conversion rate. The button is inserting the "java_error" row in the table and giving out this error:
SoapException: faultCode=SOAP-ENV:Protocol;msg=Unsupported response content type "text/html;, must be: "text/xml". Response was: <! DOCTYPE HTM
I am attaching the PL/SQL package generated out of the java class. Hope this is correct:

Please let me know where I am doing wrong.
One more thing I would like to mention is that my form builder is on UNIX server and JDeveloper is on my local machine. So I am ftp'ing the java class and the deployed JAR file into my home directory on UNIX server in "binary" mode. And in the CLASSPATH I am mentioning my home directory,So that the java class gets picked up when I import the Java class.
Thanks in advance,
