How to access environment variables from Oracle Forms

Hi,
Any idea how to use the Environment variables from Oracle Forms.
My basic problem is that from Oracle form I am calling Batch file which calls excel file with a macro.
So i want to check whether the macro was successful or not.
So in my batch file i will set %errorlevel% which I should be able to read from Oracle Forms.
I am able to read the registry from oracle forms, so is there anyway to read environment variable as well?
Thanks!
Avinash.

Hello,
Use the TOOL_ENV.Getvar() built-in

How to access environment variables from pluggable destination?

Hi,
I'm trying to create a java puggable destination for reports. Everything is working fine.
I want to access reports environment variables from the java code (like REPORTS_PATH and other new variables that I want to create), but I can't find anything about this in the java API documentation.
I want to use environment variables instead of destination properties (those I can easily access), because I want to be able to change context using env_id.
Any ideas?
Thanks,
Luis

I'm using Oracle Application Server Version 10.1.2.0.2

How to invoke crystal reports from Oracle forms 11g R2 along with passing p

How to invoke crystal reports from Oracle forms 11g R2 along with passing parameter to it.
how to pass parameters to crystal report, please help.

how to pass parameters to crystal report, please help.This would entirely depend on crystal reports and you might find informations on crystal reports related communities more likely...I for one have seen crystal reports the last time about 12 years ago. And even back then I simply acknowledged it's existence instead of working with it.
Maybe crystal reports can be invoked via a URL call which would make it simple as you'd need simply build an URL and show the report using web.show_document. But that's pure speculation. Also you might not be the first with this requirement, so the solution to your problem might be right under your nose and just a little google search away ;)
cheers

How to print BIP reports from Oracle Forms?

Hi all,
I have a question in regards to printing BIP reports from Oracle Forms... We are aiming for a server installation of BIP with integration to Oracle Forms using SSO to handle security. We use Forms built-in web.show_document to render and view the report in PDF/Excel etc... We would like to by pass the viewing and print some of these reports directly to the printer.
Any idea/suggestions how we can go about this?
Thanks in advance for your time.
Yahya

Yahya,
via HTTP it's not possible to send a report directly to the printer. You had to go via the Scheduler, which is able to do that. With the WebService API you can call a report with the Scheduler and Execute Immediate.

How to insert special character from Oracle form builder 10g

Dear all,
I need help. how to insert special character like 'Superscript or Subscript ' from oracle form builder 10g. I had try in Oracle form builder 6i with press ALT+ASCII code in the text item and it work, but in the oracle form builder 10g this method doesn't work... would you like to help me...somebody please...
Best Regard,
Dedy P.T.

What do you mean by insert ... from Forms Builder? Do you mean you want to add it as text in a string of pl/sql code or as part of boiler plate text (label) or a value on the Property Palette?
For special characters you would need set NLS_LANG to something that would support the characters you want to use. For the Builder to see the change, you would need to set NLS_LANG to something like:
NLS_LANG=AMERICAN_AMERICA.UTF8
This can be done in the Windows Registry or system. As I mentioned, this will only apply to the Builder and will have nothing to do with a running form. For running forms you would need to set this in default.env. As for things like super and sub scripts, these are font formats and not necessarily characters. For the most part, I don't believe these are supported in Forms.

How to open .cmdrw file from Oracle Forms 10g

Hi,
We need to call *.cmdrw* file from Oracle forms 10g. Is there any way to call *.cmdrw* file from Oracle forms 10g?
Thanks for the help.
Viishnu Nekkanti

In case you want to open a .cmdrw with its associated application you can use the following procedure:
webutil_host.NonBlocking( 'rundll32 url.dll,FileProtocolHandler ' || client_filename );This works for every file where a program has been associated to its file extension. (Adobe Reader for *.pdf, Microsoft Word for *.doc, Microsoft Excel for *.xls and so on)

How to access a variable from within a symbol.

How do I access a variable set outside a symbol from within that symbol?
Thanks

If you set a variable on stage ,say
sym.setVariable("stageVariable", "I am stage variable");
You can access it from within a symbol using :
var myVariable = sym.getComposition().getStage().getVariable("stageVariable");
Basically you need to get handle to the symbol in which the variable is defined.

Access Flat Files From Oracle Forms Using Simba

Hi,
I need to access Flat Files using Simba and display the data using Oracle Forms on Solaris. The Flat Files, Simba and Oracle Forms is on Solaris.
Thanks.
Sanjay R Naidu.

Hi,
not knowing the flat file's format and why you need SIMBA for it, Forms provides a text_io package that can read from files. You need to parse the file's content and then bring this to a datablock.

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.

How to invoke environment variables from a remote server

Hi Guys;
I am new to java programming and have very basic knowledge. I am trying to get some environment variable information from a remote server. I have created a program that gives me the env variables from my machine but I need to connect to some other server and bring those variables.
Can someone help me with this?
Regards,
Aditya

there is no way to get that information from a remote machine without that machine having some program installed on it that you can poll to ask for it (and no machine should have a program like that on it, it's a potentially massive security hole).

How do you extract SQL from Oracle Forms and Reports files?

I am developing an "as is" data model for a government client for a 14 year old system that has three databases, 20 schemas, over 1500 tables, and over 23,000 columns. Needless to say, I do not plan to perform a manual mapping of data to screens and reports.
Most of the system has been developed in Oracle Forms and Reports. I am trying to map the live tables and columns to forms and reports.
The process here has been to save the forms and reports files as .fmb and .rdf files. The client does not have an available copy of Oracle Designer, which I understand could be used to extract the SQL.
Is there a utility somewhere that can parse the .fmb and .rdf files to extract the SQL?
Thanks,
Jim Gearing

Jim,
I don't know of any utility that will do this. You can convert and save each fmb as a fmt so you can view/search the contents , but I don't recommend that approach.
On the other hand, you download a copy of Oracle Designer:
http://www.oracle.com/technology/software/index.html
It usually is included with Oracle Forms and Reports.

Please i will appreciate if anybody has any documentation or can give me step-by step instruction .
I am new in EP .

Hello Avinash,
You can directly use query in form personalization Conditions like
select date_probation_end from per_assignments_x where person_id = :PERIOD_OF_SERVICE.PERSON_ID
and put in your condition like if you want to validate Probation end date is less then sysdate then in condition put in like.
TRUNC(SYSDATE) < (select TRUNC(date_probation_end) from per_assignments_x where person_id = :PERIOD_OF_SERVICE.PERSON_ID)
set the error message.

Saurabh

How to access (call) variables from multiple components

I have what I think is a basic task, but I cant seem to get it to work. I have a Flex project with one application. In addition to the one application, I have many components that are used in the application. These components vary from simple (a ComboBox) to complex (many sub-components). What I need to do is define a viable in one component and access it in another component. I can't seem to do this. Below is an example of how I think it should be:
Component1
<mx:Script>
       <![CDATA[
        [Bindable]
        private var userID:int=0;
       ]]>
</mx:Script>
Component2
<mx:TextInput text="{Component1.userID}"/>
Any help you can provide would be beneficial.
Lee

Hello,
     You may also want to consider using the mx.core method.
     In your main application script area define all of your public variables and functions. Then from your component, you can reference these absolutely with the following syntax.

[Bindable]
public var userID:int;

private function init():void {
     var com_UserID = mx.core.Application.application.userID;
Using this method ensures that you will have access to any Function or variable within the scope of the project.
