Send email to muliple clients using Oracle Forms 6i through MS Outlook 2003

Question

I am working on oracle Forms 6i and Oracle 9i (9.2.0.1) database. My requirement is How to trigger email sending to multiple clients at a time while using Oracle Forms 6i through Microsoft Outlook 2003?
To do this I have written the following code.
PROCEDURE send_mail IS
OutlookApp OLE2.OBJ_TYPE;
NameSpace OLE2.OBJ_TYPE;
MailItem OLE2.OBJ_TYPE;
OLEPARAM OLE2.LIST_TYPE;
Send OLE2.OBJ_TYPE;
Attachments OLE2.OBJ_TYPE;
Attachment_dummy OLE2.OBJ_TYPE;
var1 varchar2(1000);
Begin
var1 := :mapiole.message;
OutlookApp := OLE2.CREATE_OBJ('Outlook.Application');
OLEPARAM := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(OLEPARAM,'MAPI');
NameSpace := OLE2.INVOKE_OBJ(OutlookApp,'GetNameSpace',OLEPARAM) ;
OLE2.DESTROY_ARGLIST(OLEPARAM);
OLEPARAM := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(OLEPARAM,0);
MailItem := OLE2.INVOKE_OBJ(OutlookApp,'CreateItem',OLEPARAM);
OLE2.DESTROY_ARGLIST(OLEPARAM);
OLE2.SET_PROPERTY(MailItem,'To',:to);
OLE2.SET_PROPERTY(MailItem,'Subject',:subject);
OLE2.SET_PROPERTY(MailItem,'Body', var1);
--add an attachment
if :mapiole.attach is not null then
Attachments := OLE2.GET_OBJ_PROPERTY(MailItem,'Attachments');
OLEPARAM := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(OLEPARAM,:attach);
Attachment_dummy := OLE2.INVOKE_OBJ(Attachments,'add',OLEPARAM);
OLE2.DESTROY_ARGLIST(OLEPARAM);
end if;
Send := OLE2.INVOKE_OBJ(MailItem,'Send');
--destroy objects
OLE2.RELEASE_OBJ(MailItem);
OLE2.RELEASE_OBJ(NameSpace);
OLE2.RELEASE_OBJ(OutlookApp);
END;
Create a block called MAPIOLE with the following canvas layout:
To:      ============================
Subject: ============================
Message: ============================
============================
Attachment: ============================           SEND      
When I press the SEND button then
Error comes "FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception
ORA-305500
How can I do this?
Please help me.
Thanks.

Answer 1

Do you have a requirement to use MS-Outlook from the Client or simple send email to a list of recipients? If the requirement is simply to send email to a list of recipients, I suggest you use UTL_SMTP from the database to send your email rather than OLE to Outlook on the Users computer. Search OTN or the forums for 'MAILDEMO' and you will find many examples on how to send email from the database.
Hope this helps.
