[DUG] ISAPI upload problem

[Jeremy Coulter]

I came across some code for doing it in a CGI app, and converted it to a COM 
app that uses the ASP engine in Delphi, and I THINK I still have the code 
for teh CGI app. somewhere.
Email me offline if you want it.

Thanks for the replies everyone - I've been on a course all day so have only 
just read them now.

I am using the "multipart/form-data" method="post" that Trevor gave an 
example of (no web broker). So I think it was a case of needing to keep on 
reading.

Thanks for the attachment trevor - I will give it a go.

Cheers,
Phil.

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

I have an ISAPI DLL written in Delphi that provides a form 
for uploading a CSV file. When I try to upload the CSV file 
it only manages to handle
678 lines and then produces an error (there should be over 
1000 lines). 
Is there some special handling I have to do to handle uploading files?

At the moment all I am doing is reading the 
Request.ContentFields property to access the strings from the 
uploaded file.

Cheers,
Phil.
