Exemplos

O exemplo a seguir cria uma nova HierarchyInfo instância e adiciona dois itens à Properties propriedade .

internal class DemoHierProvidr : HierarchyProvider
{

    private DemoHierarchyInfo _info;
    public DemoHierProvidr(IServiceProvider serviceProvider)
        : base(serviceProvider)
    {
    }


    public override HierarchyInfo[] GetChildren(HierarchyInfo item)
    {

        Trace.WriteLine("NodeType = " + item.NodeType +
            "\t name = " + this.ToString());
        // if we are at the Server level, add our node
        if (item.NodeType == HierarchyInfo.ServerConnection)
        {
            if (_info == null)
            {
                _info = new DemoHierarchyInfo(this);
            }
            return new HierarchyInfo[] { _info };
        }

        return null;
    }

public DemoHierarchyInfo(IServiceProvider serviceProvider)
    : base(serviceProvider)
{
    DemoHierarchyInfoInit();
    initTraceP();
}

internal class DemoHierarchyInfo : HierarchyInfo

    private static string sMachine = "Machine";

    public DemoHierarchyInfo(IServiceProvider serviceProvider)
        : base(serviceProvider)
    {
        DemoHierarchyInfoInit();
        initTraceP();
    }



    // return rLoadImg.loadImgs("rTool.bmp");
    //System.Drawing.Image.FromFile("rTool.bmp");

    public void flush()
    {
        _objStrm.Flush();
    }

    void initTraceP()
    {
        try

            TextWriterTraceListener objTraceListener = new TextWriterTraceListener(_objStrm);
            Trace.Listeners.Add(objTraceListener);
            Trace.WriteLine("-----  " + System.DateTime.Now.ToString());
            Trace.Flush();
        } catch (System.IO.IOException six)
        {
            MessageBox.Show("C:\\AppLog.txt cannot be created \n" +
                six.Message,
                "Tracing disabled");
        }


    }

    protected override void Dispose()
    {
        Trace.WriteLine("\n ----- Clean Dispose/Flush " + System.DateTime.Now.ToString()
            + "----- \n");

        Trace.Flush();
        _objStrm.Flush();
        return;
        //_objStrm.Close();
        //base.Dispose();
    }

    private void DemoHierarchyInfoInit()
    {
        System.Collections.IDictionary d = Properties;
        d.Add(sMachine, System.Environment.MachineName);
        d.Add(sOS, System.Environment.OSVersion.ToString());
        Trace.WriteLine(" ctor called (DemoHierarchyInfoInit) ");
    }
