[DUG] ISAPI upload problem

[Stephen Barker]

Hi Phil,

The problem is likely that the ContentFields property only contains the
first chunk of the file. You have to keep reading up to the content length
to get the full data.

Are you using web broker?

I don't use that - I just use straight ISAPI, but I've got some code for
this if it helps:


  TotalBytes := FECB.cbTotalBytes;   //Request.ContentLength;
  sContentType := FServerVars.values['CONTENT_TYPE'];
  p:=Pos('boundary=',LowerCase(sContentType));

  sl := TStringList.create;
  try
    if p>0 then begin
      boundary:='--'+trim(copy(sContentType,p+9,length(sContentType)));
      ParseMultipart(TotalBytes, FECB,
FECB.lpbData,FECB.cbAvailable,boundary,sl,sFileName);
    end;
  finally
    sl.free;
  end;

Plus there's more you might want in the ParseMultipart function.


Regards,
Steve
