Sending attachment using TIdAttachment in c++ builder
How to send attachment using TIdyAttachment ?
How to convert this TIdAttachment.Create(msg.MessageParts, 'c:\at开发者_运维问答tach.bmp');
delphi statement to c++ builder ?
How to use this abstract class in c++ builder? Due to it's being abstract I cannot create an instance of it !!!
Note that TIdAttachment
is indeed abstract (as Remy Lebeau noted in a comment). Use TIdAttachmentFile
instead. In C++, I guess it should look like (Update: I see you already found that):
TIdAttachmentFile *attachment = new TIdAttachmentFile(msg->MessageParts, "C:\\attach.bmp");
FWIW, named constructor calls like TMyClass.Create(args)
in Delphi are translated as new TMyClass(args)
in C++Builder. That is why Delphi often overloads Create
, instead of using differently named constructors like CreateWithSpecialParams
. In Delphi, a constructor can have any name, but not in C++.
Note that in Delphi you can have a constructor Create(Integer)
and a constructor CreateEx(Integer)
and they are distinguishable. This is not translatable to C++Builder, since both translate to MyClass(int)
, so doing that should be avoided if the Delphi programmer wants his or her class to be usable in C++Builder.
