SecureBridge does not allow you to cancel the operation of downloading/loading a file.
If you want us to add this functionality, please write about it at our User Voice forum: https://devart.uservoice.com/forums/174370-securebridge. If your suggestion gets enough votes, we will consider the possibility of its implementation.

This is a failure. This is the basic function in file operations....

I found this solution
viewtopic.php?t=19149
it seems to work.

Code: Select all

procedure TSFTPClientFrame.ScSFTPClientSuccess(Sender: TObject;
  Operation: TScSFTPOperation; const FileName: string;
  const Handle: TArray<System.Byte>; const Message: string);
begin
  if IfNeedAbort then
    raise Exception.Create('Custom break file operation');
end;
Is this the right solution to my question?

Yes, please add a function/property to abort upload/download. It is very necessary and not a big work, so I don't think it need a separate vote for this functionality. Thanks.

If we add a parameter to the event handler, this will change the standard behavior of this component, which has been used by our users for many years and this will affect all of them. Therefore, we asked you to write about it at https://devart.uservoice.com/forums/174370-securebridge. If your suggestion gets enough votes, we will consider the possibility of its implementation.
