Try

gvEvents.Columns[0].Visible = true;

I am down to two errors!  Yeah! 
Now I have a new issue.

VB Code:
Namespace DotNetNuke.Modules.Events

    Partial Class EventIcons
        Inherits DotNetNuke.Modules.Events.EventBase
        Private MyFileName As String = Me.GetType().BaseType.Name + ".ascx"

        Protected Overloads ReadOnly Property LocalResourceFile() As String
            Get
                Return Services.Localization.Localization.GetResourceFile(Me, MyFileName)
            End Get
        End Property

C Sharp Code:  (I need to figure out how to get the keyword 'this', or some other way of getting the BaseType Name.
namespace DotNetNuke.Modules.Events
{

    partial class EventIcons : QHWeb.Modules.Event.EventBase
    {
        private string MyFileName = this.GetType().BaseType.Name + ".ascx";
                                                           ~~~  <- Keyword this does not exist in this context.
        protected string LocalResourceFile {
            get { return Localization.GetResourceFile(this, MyFileName); }
        }

I found the solution.  The private won't work, but bringing the text into the function actually worked..


        protected string LocalResourceFile {
            get { return Localization.GetResourceFile(this, this.GetType().BaseType.Name + ".ascx"); }
                                                                                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        }
