I want to export a particular schema among various schemas on forms 6i.
To achieve this, I am using the list of values (lov) on forms 6i for the selection of schema name. I attached this lov to a display item called (1).
On run time, I select the value (user name) from lov and then this selected value store in display item (1). Then I execute the button (export), inside this button following coding is written:

The code:

--trigger when button press

BEGIN

HOST('F:\EXP_SCHEMA_F.BAT 1');


IF NOT Form_Success THEN
Message(' EXPORT TERMINATED SUCCESSFULLY WITH WARNINGS.');
ELSE Message('EXPORT TERMINATED SUCCESSFULLY WITHOUT WARNINGS.');
End if;
END;




I am passing the name of schema which stores in the display item (1) to the batch file.
Export is invoke but not successful and show the error that “S1” IS INVALID USERNAME.


THE CODING OF BATCH FILE IS :

@echo off
if not exist f:\export_schema mkdir F:\export_schema
del/q f:\export_schema\*

set owner=%1

if "%1" == "" goto usage

exp system/manager file=f:\export_schema\exp_schema.dmp
owner=%owner%

goto end

:end

set owner=




Could you please assist me in this regard that how to pass the user name/schema to the host command for exporting a particular schema, on forms 6i.

Furthermore I want to wrap a package via forms 6i, when I select the package with radio button, in order to secure the code. I am using host command on forms to do that but the problem is same as above, how should I pass the package name and owner name to the host command in order to wrap the package. I am using wrap utility.


I will be thankful to you.

Yours Sincerely,

Faraz
