title: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding
body: <p>When I run my code I get the following exception:</p>
  <blockquote>
  <p>An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll</p>
  <p>Additional information: Execution Timeout Expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.</p>
  </blockquote>
  <p>My code is the following:</p>
  <pre><code>    private void FillInDataGrid(string SQLstring)
      {
          string cn = ConfigurationManager.ConnectionStrings[&quot;Scratchpad&quot;].ConnectionString; //hier wordt de databasestring opgehaald
          SqlConnection myConnection = new SqlConnection(cn);
          SqlDataAdapter dataadapter = new SqlDataAdapter(SQLstring, myConnection);
          DataSet ds = new DataSet();
          myConnection.Open();
          dataadapter.Fill(ds, &quot;Authors_table&quot;);
          myConnection.Close();
          dataGridView1.DataSource = ds;
          dataGridView1.DataMember = &quot;Authors_table&quot;;
      }
  </code></pre>
  <p>And my SQLstring is the following:</p>
  <pre><code>SELECT dbo.[new].[colom1],dbo.[new].[colom2],dbo.[new].[colom3],dbo.[new].[colom4],  
                  dbo.[new].[Value] as 'nieuwe Value',
                  dbo.[old].[Value] as 'oude Value'
                  FROM dbo.[new]
                  JOIN dbo.[old] ON dbo.[new].[colom1] = dbo.[old].[colom1] and dbo.[new].[colom2] = dbo.[old].[colom2] and dbo.[new].[colom3] = dbo.[old].[colom3] and dbo.[new].[colom4] = dbo.[old].[colom4] 
                  where dbo.[new].[Value] &lt;&gt; dbo.[old].[Value]
  </code></pre>
