I have been trying to get this web part called "Documents today" to work. it
is from the MSDN article called "how to customize your search using SPS 2003."

I have compiled to code, and loaded it registers as safe, but the web part
doesn't do anything...nothing no errors.

I was wodnering if some one out there might be able to point out what is
needed to be changed or fixed in order for this webpart to work.

Code is below:
using System;
using System.Data;
using System.Text;
using System.ComponentModel;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Xml.Serialization;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.WebPartPages;
using Microsoft.SharePoint.Portal.Search;
using Microsoft.SharePoint.Portal;

namespace documentstoday
{
/// <summary>
/// Description for WebPart1.
/// </summary>
[DefaultProperty("Text"),
ToolboxData("<{0}:documentstoday runat=server></{0}:documentstoday>"),
XmlRoot(Namespace="documentstoday")]
public class documentstoday : Microsoft.SharePoint.WebPartPages.WebPart
{

private Label labelResults = null;

protected override void CreateChildControls()
{
this.labelResults = new Label();

DataSet ds = null;
try
{
PortalContext context = PortalApplication.GetContext();
QueryProvider qp = new QueryProvider(context.SearchApplicationName);
string query =
"SELECT \"DAV:href\",\"DAV:displayname\",
\"urn:schemas-microsoft-com:office:office#Author\" " +
"FROM Portal_Content..Scope() " +
"WHERE (\"urn:schemas.microsoft.com:sharepoint:portal:isdocument\" = 1)
AND " +
"(\"DAV:creationdate\" > DateAdd(Day, -1, GetGMTDate()))";
ds = qp.Execute(query);

StringBuilder sb = new StringBuilder();

if(ds != null)
{
sb.Append("<UL>");
foreach(DataRow dr in ds.Tables[0].Rows)
{
sb.AppendFormat("<LI><A href='{0}'>{1}</A> added by {2}</LI>",
dr["DAV:href"].ToString(),dr["DAV:displayname"].ToString(),
dr["urn:schemas-microsoft-com:office:office#Author"].ToString());
}
sb.Append("</UL>");
}
else
{
sb.Append("<P>No new documents added today</P>");
}

this.labelResults.Text = sb.ToString();
}
catch (Exception ex)
{
this.labelResults.Text = ex.ToString();
}

this.Controls.Add(this.labelResults);
}

protected override void RenderWebPart(HtmlTextWriter output)
{
this.EnsureChildControls();
this.labelResults.RenderControl(output);
}
}
}

this is the error code that the web part generates:
System.NullReferenceException: Object reference not set to an instance of an
object. at documentstoday.documentstoday.CreateChildControls() in
c:\documents and settings\atheysd\my documents\visual studio
projects\documentstoday\documentstoday.cs:line 35
