Using vba in Oracle Forms 6i

Hello
I'm working with Oracle Forms 6i and I need to check if a certain folder exists before I make an action, I think there's no way to do it with Oracle Forms only, so I tough doing it with vba.
Is there some controller that allow me to use vba in Oracle Forms? Or maybe I can do this another way.
Thanks

You can use this piece of code to check if a directory exists:
declare
l_hostcommand varchar2(1000);
l_dir          varchar2(200) := 'f:\oracle';
begin
l_hostcommand := 'cmd /c if not exist '||l_dir||' exit 100';
host(l_hostcommand, no_screen);
if form_success then
    message('Directory found');
else
    message('Directory not found');
end if;
end;   If you have no drive mapping, just use UNC (\\server\oracle).

How to use css in oracle forms

Hello, I am using oracle forms 11g with weblogic server 10.3.5 at windows 7.I have to use CSS in oracle forms.i have tried to search it but no profit.please some one else tell me that how can use css in oracle forms. Thnak You regards aaditya

Hi
As Francois pointed out Oracle forms has nothing to do with html based technology. The way you can get the equivalent effect of creating consistancy in the way your objects are displayed is by creating a set of items you want and alter their apperance and behaviour and place them into object libraries (one library should do the trick). From there you subclass all of you forms items off these libraries.

Using jfreechart with oracle forms 11g

Hi everybody,
I'm using jfreechart with oracle forms 11g to continue having graphs in my application since i'm migrating from forms 6i. I've already got it working and it's great. Just have one problem left. I don't know how to change the axis labels. In Bar charts, it comes with "Values" in y axis and "Category" in x axis by default. I wanted to change that or make it dissapear. Anyone knows how to?

I've never used the jFreeChart, but according to their website you can use the "setLabel" method to set the label for an axis. Check out Axis (JFreeChart Class Library) for more information.

Can we use WebUtil with Oracle Forms 6i

Can any one tell me if we can use WebUtil with Oracle Forms 6i..I have 11.5.9 instance of oracle apps and i want to use some features of WebUtil to customize one of seeded Oracle Form.
Any pointers in this regard are quiet welcome.
Thanks,

Strictly speaking no...however you could "backport" the webutil code and in theory you could get some of the functionality to work - this is not supported in the context of oracleForms although Oracle Applications may have their own specific solution/certification of this.

Hi Torsten Kleiber

i have specific questions with JDAPI will i be able to change my buttons in a form to Iconic buttons.
Could you kindly send me the code of your class in the abovementioned post (I have created a simple class to modify some forms properties.)
I would like to have alook at it i am a Novice in java but looking at your source code may be able to give myself a head start .(I am well versed pl/sql forms and reports NO JAVA idea)
Two while trying out the oracle demo to create a form by jdapi I was able to create a class and was unable to execute it .What do i need to install to execute it. I have forms 10 installtion with Jinitiator 1.3 installed
DO i need to install Jdeveloper or JDK i think either of this is required. I shall be highly be obliged if u can clear my queries or any one else in the forum may wish to add to 2cents to my infinetly minimal knowledge of java

How to use LDAP with Oracle forms 10g on Oracle application server

Hi,
I need some help on this. I have developed oracle forms 10g on application server 9iAS. The client want to use the existing LDAP authentication to the software we wrote. I do not know how I could configure to use the existing LDAP authentication . If anyone know how would I use the existing LDAP on different server to use when they logon to our menu in 10g to validate the user. Do I need to add any varibales in formweb.cfg or any other method. Please help.
Thanks
Luksh

I am not quite sure if this works out of the box. According to an Oracle FAQ:
4.2 Can I use LDAP to authenticate Forms Services?
Not directly. However, Oracle Login Server is able to authenticate against a LDAP directory and thus a Forms application can take advantage of this in a SSO environment. But you cannot use access control information stored in a LDAP directory with Forms.

In which trigger can i use go_item() in oracle forms 6i?

Hi,
I have a problem with go_item.
I tried executing go_item() in triggers like key_next_item, pre_text_item, post_text_item & when_validate_item.
But none of them seemed to be working.
I searched for other possibilities in the site, where i found a solution of using trigger ' when_timer_expired ' with ' when_validate_item ' ,
but when i tried to create trigger, i did not find that trigger (when_timer_expired) in the list at all.
I'm using oracle form builder 6i.
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production.
A trigger with go_item() must be created when tab is pressed.
In which trigger can i use go_item() ??
Thank You.

from help:
Restricted Built-in Subprograms
Restricted Built-ins affect navigation in your form, either external screen navigation, or internal navigation. You can call these Built-ins only from triggers while no internal navigation is occurring.
Restricted Built-ins cannot be called from the Pre and Post triggers, which fire when Oracle Forms is navigating from object to another.
Restricted Built-ins can be called from the When triggers that are specific to interface items, such as When-Button-Pressed or When-Checkbox-Changed. Restricted Built-ins can also be called from any of the When-New-"object"-Instance triggers and from key triggers.
Unrestricted Built-ins do not affect logical or physical navigation and can be called from any trigger.
The Built-in descriptions include a heading, Built-In Type, that indicates if the Built-in is restricted or unrestricted.

Is it possible to use DVT with Oracle Forms 11g?

I have posted my question on Oracle Forms forum but I didn't get answere regarding dvt usage in Oracle Forms.
Now I try it here.
Oracle Forms 11g and charts / graphs
====
one of our customers has a forms 6i applications including oracle graphics and is thinking about upgrade to forms 11g.
Oracle graphics has been desupported with 6i and with 9i Oracle BI beans has been recommended.
Forms 10g is the terminal version for Oracle BI beans too (http://www.oracle.com/technetwork/middleware/bbi-beans/overview/oraclebibeanssod2008-129560.pdf).
What's the recommended technology for graphs/charts in Forms 11g?
Is it ADF DVT?
If yes, are there examples how to call them from Forms 11g?
=====
regards
Peter

Hello Shay,
thank you very much for the link.
I wonder if there any plans from Oracle to provide and support a DVT wrapper in next versions of Oracle Forms 11g
As the customer project is planned for Q2/2011 we still have some time and hope for this :-)

END;
I am facing a problem, I will appreciate if you can give some insights to help.
We have been having problem logging in to application when there are a number of EXCEL processes running (17-18) on the server. Users that have already logged in have no problem, but new login will get "FRM-92101 There was a failure in the Forms Server during startup". The Forms Server itself is running fine. After we killed a few EXCEL processes, new users will be able to login.
Thanks and regards,
Mandeep

Using graphics in oracle forms 10g

i've read everything in this thread:
http://download.oracle.com/docs/cd/B12166_01/web/B10469_01/repgrph.htm
but i cannot run graphics.
there is the next error:
OG-01603: Unable to create Pl/SQL Development Environment context.
do you know how to prevent this error?
i did:
*install oracle developer suite 6i on application server (different home)
*configure linux application server to work with graphics 6i
*compile og.pll
*compile form
best regards, Teodor

you have to do the migration one time. Better now than in the future. One day a forms patch will say: Graphics is now obsolete, please migrate.
To run a 6i graphics service on a 10g platform is (please believe me) the badest way to run your old graphics in the new world.
its like toothache. you can eliminate them through eating 10 aspirins each day. But you know, that you have to go one day to the dentist...

JUNIT in Oracle Forms 6i

Hi
We are using Oracle Forms 6i to develop Oracle Applications form extensions.
Wanted to know if we use JUnit in Oracle Forms for testing?
Thanks
Rahul

Hi there
Thanks for the response.
I was thinking of Forms Data Loader to use as an option for unit testing in Oracle Forms since it does capture the events like button submit , but I dont think it does any verification of data like JUnit.
Please let me know what do you think of same.
Thanks
Rahul
