I hope tat any one who is experience this things b4 can teach wat i shoud do.. thanks <br><br>tat is the error wen i compile it<br><br>Parser Error <br>Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. <br><br>Parser Error Message: Could not load type 'OnlineBookStore.button'.<br><br>Source Error: <br><br><br>Line 1: <%@ Page Language="vb" AutoEventWireup="false" Codebehind="button.aspx.vb" Inherits="OnlineBookStore.button"%><br> <br><br>Source File: C:InetpubwwwrootOnlineBookStore utton.aspx Line: 1

I'm not sure about that, but it seems to be an inherit error. So, you can try one thing: be sure that on the header of the .vb file, it's specified the library where the properties of the buttons are (something like using System.Web.UI.Webcontrols).<br>If this is not enough to solve your problem, take care about using the same name always when you refer to the same control.<br>I hope I was helpful.
