Forms to Excel (OLE2 and macro)

Question

Hi,
I am using OLE2 to export data from Forms to Excel. Once I export the data into an excel spreadsheet successfully, I would like to format the worksheet. I have created a macro to do that and try to call the macro from Forms.
I am getting Ora-305500 and Excel starts but the worksheet doesn't open.
Is it something to do with the way I created/saved my macro?
Please help!
DECLARE
application ole2.obj_type;
workbooks ole2.obj_type;
workbook ole2.obj_type;
args ole2.list_type;
BEGIN
application:=ole2.create_obj('Excel.Application');
ole2.set_property(application, 'Visible', 'True');
args:=ole2.create_arglist;
ole2.add_arg(args, 'C:\excel.xls');
workbook:= ole2.invoke_obj(workbooks, 'Open',args);
ole2.destroy_arglist(args);
args:=ole2.create_arglist;
ole2.add_arg(args, 'c:\personal.xls!acrt_macro');
ole2.invoke(application, 'Run', args);
ole2.destroy_arglist(args);
--ole2.invoke(application,'Quit');
ole2.release_obj(workbook);
ole2.release_obj(workbooks);
ole2.release_obj(application);
END;

Yes, it is possible to read from & write to an excel file.
you have to use the DDE package to achieve your goal. Read the help content for DDE package, which explains in detail.
