If the solution to this is already out there, then I apologize but I did some searching and could not find it.  We are using DNN 4.5.4 and I am developing a module in C#.  I have a problem with the following code:

                            string strUrl = NodeInfo.URL;
                            if (strUrl.ToLower().StartsWith("fileid="))
                            {
                                objFileInfo = objFileController.GetFileById(Int32.Parse(strUrl.Substring(7)), PortalId);
                                strUrl = objFileInfo.Folder + objFileInfo.FileName;
                            }
                            UrlControl.Url = strUrl;

If the NodeInfo.URL is something like 'FileID=1', everything works fine.  However, if the NodeInfo.URL is something like 'http://www.dotnetnuke.com' , the assignment will not work.  I have even tried doing a direct assignment via the immediate window in the VS IDE without success.  Any help would be appreciated!
