hi
try something like this.
DECLARE
charWinHandle VARCHAR2(50);
numWinHandle NUMBER;
BEGIN Set_Application_Property(Cursor_Style,'BUSY');
charWinHandle := Get_Item_Property('Control.Rep',Window_Handle);
numWinHandle := To_Number(charWinHandle);

Set_Application_Property(Cursor_Style,'DEFAULT');
END;NOTE: Change the report name and path according to your required file name and path in
the "Crystal_CrystalCtrl.ReportFileName" method call. Also, the connection string shown
assumes that you will use the current USER and PASSWORD for the Form.
- To make the above Form generic so that you can run any Crystal report from it, then create
a parameter for the report name and pass it to the Form using CALL_FORM from any other Form.
Then just replace the file name with the passed parameter.
-. Run the Form
If its correct/helpful please mark it thanks.

Insert / Update from Oracle Forms -- URGENT Please thanks

Hello All,
I need to create form which can be use for two purposes. i.e insert and update
I have one table called emp which has 50 columns.
Only four columns has not null constraint.
I need to insert values in only these columns.
From SQLPLUS it can be cone as below:
insert ito emp values ('333','2222','007','AA','01-JAN-2007','','','','','','','','','',........);
After that I need to update one of the coulmn with the value as
update emp
set zipcode = 'Y'
where empt# = 007;
How could I achive this from Oracle form.
Any help will be appricated.
D

Why handle updates in the On-Update trigger? Oracle Forms already handles this for you. You update a data value in a field and click on the SAVE button (assuming you have a Save button) and the Oracle Forms handles the Update. The On-Update trigger is provided so you can perform processing in addition to the default UPDATE.

Calling web service from oracle forms 10g

Problem Description:

Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
The code from oracle form to call web service is as below:

END;
Any help/ideas on this is greatly appreciated. Thanks.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.

Call Oreacle report from Oracle form

Hi,
I need call a Oracle report from Oracle Form and found the the following procedure from this forum. I have 2 parameters 'start_date' and 'end_date' passing to called report. The following example just have onle parameter

add_parameter(plid, ''start_date' , TEXT_PARAMETER,:control.start_date);
add_parameter(plid, ''end_date' , TEXT_PARAMETER,:control.end_date);

How to call pdf files from oracle forms

I have a pdf file in the server , I need to call this and open when a button is pressed in the oracle forms.
Please let me know how to do this.
Thanks,
Previn

Frank,
I have oracle applications and I want to open a pdf file located in the server from a button in oracle applications.
Previn,
you don't mention the Forms release you are running.
If you are running Forms on the web, you can use
web.show_document() to load files from the Web if
they are accessible via HTTP.

Calling web service from oracle forms fails with ORA_JAVA.JAVA_ERROR

Calling Crystal Reports from Oracle Forms 10G

Hi everyone,
I am trying to call a crystal report from Oracle Forms 10G.
I have a button on my Form which when clicked calls a Crystal Report which the uaser then wants to save as a PDf file.
Can someone please send me the code to do this and also the exact steps that are to be followed.
Thanks
Fm.

Hi Andreas,
I am trying to call the crystal report from an Oracle Form using a URL. No batch file is being used here.
I am looking for a peice of code similar to run_product or run_report built in in Oracle which calls an Oracle report from an Oracle Form.
Also I dont want to display the report on a screen or a window in Oracle Forms. I would like it to run just as we run an Oracle Report from an Oracle Form.
Is that possible ? If yes please let me know the steps to do this.
Thanks

Calling Sql*Loader from oracle Form builder

How do i call sql* loader from my forms to import the external data in different formats into my existing database?
Specify the flexibility of sql* loader to import external data from .txt files or .xls files.
Would be thankful if certain examples are given along with the answer.

Hi,
1. First you have to create seperate ctl (Control files) which maps to different file formats
2. Using Oracle Forms,
2a) You can use the 'HOST' command to execute the command line ie. In this case executing
SQL*Loader script
2b) You also have the feature in ORACLE forms to read text files and load the data into
ORACLE db.
This can be achieved by using TEXT_IO package which comes with ORACLE Forms.
Hope this helps

Exception when calling web service from Oracle forms 10g

Hi All,
I am trying to integrate Oracle Forms 10g(V 10.1.2.0.2.) with Web Services.
There is a java class named 'authenticate' which is generated using Oracle JDeveloper.
This class is included in the forms application by using "Import Java Class" feature.
Forms built the following funtion based on that class:
-- Method: authenticate (Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
FUNCTION authenticate(
obj ORA_JAVA.JOBJECT,
a0 VARCHAR2,
a1 VARCHAR2) RETURN VARCHAR2 IS
BEGIN
args := JNI.CREATE_ARG_LIST(2);
JNI.ADD_STRING_ARG(args, a0);
JNI.ADD_STRING_ARG(args, a1);
message('here1');
RETURN JNI.CALL_STRING_METHOD(FALSE, obj, 'mypackage/AuthenticatorWebServiceServiceStub',
'authenticate', '(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;', args);
message('here2');
END;
However when the above code is invoked it shows the message 'here1' on the form and then throws the following exception: java.lang.Exception: java.lang.ClassCastException
Please suggest me what's wrong with the code. I appreciate your time and help.
Thanks,
Scott.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
