FYI, after I inserted my newly created module (dnn 4.3.4), I got the following error

Error: Vehicle Control is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at YourCompany.Modules.VehicleControl.ViewVehicleControl.lstContent_ItemDataBound(Object sender, DataListItemEventArgs e) in c:\Inetpub\wwwroot\DotNetNuke4Dev\DesktopModules\VehicleControl\ViewVehicleControl.ascx.cs:line 136 at System.Web.UI.WebControls.DataList.OnItemDataBound(DataListItemEventArgs e) at System.Web.UI.WebControls.DataList.CreateItem(Int32 itemIndex, ListItemType itemType, Boolean dataBind, Object dataItem) at System.Web.UI.WebControls.DataList.CreateControlHierarchy(Boolean useDataSource) at System.Web.UI.WebControls.BaseDataList.OnDataBinding(EventArgs e) at System.Web.UI.WebControls.BaseDataList.DataBind() at YourCompany.Modules.VehicleControl.ViewVehicleControl.Page_Load(Object sender, EventArgs e) in c:\Inetpub\wwwroot\DotNetNuke4Dev\DesktopModules\VehicleControl\ViewVehicleControl.ascx.cs:line 115 --- End of inner exception stack trace ---

This is the same function in which I found an error earlier and reported in my earlier post!  I've tracked the error down to this function:

 protected void lstContent_ItemDataBound(System.Object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
        {
            string strContent = strTemplate;
            string strValue = Null.NullString;

            //add content to template
            strContent = (string)Settings["template"];
            ArrayList objProperties = CBO.GetPropertyInfo(typeof(VehicleControlInfo));
            int intProperty;
            foreach (PropertyInfo objPropertyInfo in objProperties)
            {
                if (strContent.IndexOf("[" + objPropertyInfo.Name.ToUpper() + "]") != -1)
                {
                    strValue = Server.HtmlDecode(DataBinder.Eval(e.Item.DataItem, objPropertyInfo.Name).ToString());
                    strContent = strContent.Replace("[" + objPropertyInfo.Name.ToUpper() + "]", strValue);
                }
            }

            //assign the content
            Label lblContent = (Label)e.Item.FindControl("lblContent");
            lblContent.Text = strContent;
        }

The code seems to have an extra line that messes everything up.    strContent = (string)Settings["template"]; After trying to figure out the strange c# syntax and why strContent would be reassigned two lines after being initilized, I just deleted it.  Problem solved.  This funciton needs to be fixed in the template when using c#!
