Checking a URL is valid

AntHillMob

Does anyone know if there is a way to check if a URL to a webpage is valid (i.e. check for a 404 error) from within Nav. I'm playing around with record links and want to create a batch job that checks if the links are still valid.

There are 2 ways I can think to do this off the top of my head.

1) Use the IWebBrowserApp COM control (or some other control like it) to retrieve the site and check the returned content for 404 error code.
See: http://www.codeguru.com/Csharp/Csharp/cs_webservices/article.php/c5481

2) If you are using NAV 2009 R2 then you should be able to call .NET assemblies and managed C# or VB.Net code. There are a few posts of how to do this in C# and see the links below. This should be pretty easy to code & deploy.

Thanks for the response (and sorry for the delay coming back);

In case anyone else ever wants to do this:

IF ISCLEAR(XMLHTTP) THEN
  CREATE(XMLHTTP);
XMLHTTP.open('HEAD', URL, FALSE);
XMLHTTP.send;
IF XMLHTTP.status <> 200 THEN ERROR('');

Where XMLHTTP = 'Microsoft XML, v6.0'.XMLHTTP60
