今天做站,兄弟想出一个能动态变换Banner的想法,就是广告可以在后台换,图片和Flash自动判断的,很不错,拿出来分享一下

OleDbDataAdapter selectpicurl = new OleDbDataAdapter("select Purl from picflash where Ptype='index' order by Pid DESC",conn);
   DataSet selectpicds = new DataSet();
   selectpicurl.Fill(selectpicds);
   string flashpicurl = selectpicds.Tables[0].Rows[0][0].ToString();   //图片或flash的url地址
   string houzhui = flashpicurl.Substring(flashpicurl.LastIndexOf(".")+1,flashpicurl.Length-flashpicurl.LastIndexOf(".")-1);//url的后缀名
   if(houzhui=="jpg"||houzhui=="gif"||houzhui=="png"||houzhui=="jpeg")
   {
    top_mainPICorFlash = @"<img src='"+flashpicurl+"' width='820' height='280' />";
   }
   else if(houzhui=="swf")
   {
    top_mainPICorFlash=@"<object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0'
               width='820' height='280' VIEWASTEXT>
               <param name='movie' value='"+flashpicurl+@"' />
               <param name='quality' value='high' />
               <embed src='"+flashpicurl+@"'quality='high' pluginspage='http://www.macromedia.com/go/getflashplayer' type='application/x-shockwave-flash' width='820' height='280'></embed></object>";
