I'm trying to attach a file and send it....but the C++ syntax is not very 
intuitive..below is a couple of things I've tried without luck...any help 
would be appreciated - thanks.

msg->OnCreateAttachment();///this needs parms???
msg->MessageParts->Add()->ContentDescription = "TestFile";
msg->MessageParts->Add()->ContentLocation= "C:\\Ada\\Src\\plan.cpp";//seems 
to be right syntax but bombs -- bad pointer????

smtp->Connect("smtpauth.earthlink.net",587);
smtp->Send(msg);
}
catch(Exception *e)
{
::Sleep(1);
}
}
//---------------------------------------------------------------------------
void __fastcall TForm1::msgCreateAttachment(const TIdMessage *AMsg, const 
TStrings *AHeaders, TIdAttachment *&AAttachment)
{
AAttachment->ContentLocation= "C:\\Ada\\Src\\plan.cpp";
AAttachment->ContentDescription = "C:Ada.Src.plan.cpp";
}
//---------------------------------------------------------------------------

That is because you are going about it all wrong.  You need to instantiate a
TIdAttachmentFile object instead, for example:

    TIdAttachmentFile *attachment = new TIdAttachmentFile(msg->MessageParts,
"C:\\Ada\\Src\\plan.cpp");
    // set attachment's properties as needed...

Always catch exceptions by (preferrably const) reference, never by pointers:

    catch(const Exception &e)

The purpose of the OnCreateAttachment event is for you to instantiate your
own instance of a suitable TIdAttachment-derived class (TIdAttachmentFile,
TIdAttachmentMemory, or custom class) for a particular file when
receiving/loading a message, not when sending a message.  TIdMessage uses
TIdAttachmentFile by default for all inbound attachments.  For example:

    void __fastcall TForm1::msgCreateAttachment(const TIdMessage *AMsg,
const TStrings *AHeaders, TIdAttachment *&AAttachment)
    {
        // analyze AHeaders as needed...
        AAttachment = new TIdAttachmentMemory(AMsg->MessageParts);
        // or:
        // AAttachment = new TIdAttachmentFile(AMsg->MessageParts);
        // or whatever you need...
    }

The inbound attachment data will then be loaded into the object after the
event handler exits.
