Downloading a file from an URL in NAV 2009 R2

navision2009R2

I need to download a file, from an URL, in NAV 2009 R2.

I'm trying to do the following:
- request a list of files from a server using a XMLRequest => DONE
- list the files on a form so that users can select the desired one => DONE
- download the file from the same server into the users' TEMPORARYFOLDER => TODO.

How can I proceed ?

PS:
- I tried using a DotNet variable, but itt seems like on cannot use System.Net.HttpWebResponse in NAV 2009 R2
- I succed in opennig the file in iexplore using HYPERLINK(myUrl) so netwok config is OK
- Most of the time, files will be PDF ones, but it could also be so other file formats. You can assume I know the file format of the one need to download.
- The files are on an on-premise server, so you can assume downloading thoses files are safe.

Hello @navision2009R2 ,

You can use something like this:

OBJECT Codeunit 50001 Download File from URL
{
  OBJECT-PROPERTIES
  {
    Date=28/11/20;
    Time=23:02:06;
    Modified=Yes;
    Version List=DL FILE;
  }
  PROPERTIES
  {
    OnRun=BEGIN
          END;

  }
  CODE
  {
    VAR
      [email protected] : Boolean;

    PROCEDURE [email protected]([email protected] : Text[1024];[email protected] : Text[1024]);
    VAR
      [email protected] : Automation "{F5078F18-C551-11D3-89B9-0000F81FE221} 6.0:{88D96A0B-F192-11D4-A65F-0040963251E5}:'Microsoft XML, v6.0'.ServerXMLHTTP60";
      [email protected] : InStream;
      [email protected] : OutStream;
      [email protected] : TEMPORARY Record 79;
    BEGIN
      IF ISCLEAR(XmlHttp) THEN
        CREATE(XmlHttp, FALSE, NOT ISSERVICETIER);

      XmlHttp.open('GET', URL,0);
      XmlHttp.setTimeouts(10000,10000,10000,100000);
      XmlHttp.send('');

      IF XmlHttp.status = 200 THEN BEGIN
        InStr := XmlHttp.responseStream;
        CompInf.Picture.CREATEOUTSTREAM(OutStr);
        IF COPYSTREAM(OutStr, InStr) THEN
          CompInf.Picture.EXPORT(FileName);
      END;

      CLEAR(XmlHttp);
    END;

    BEGIN
    END.
  }
}
