<i><b>Originally posted by : Mike (mike.mitchell@sumcousa.com)</b></i><br />I'm getting a "specificed cast not valid" error on the "objSendingPage=CType(Context.handler,SMSView)" line below.<br />SMSView is the class name for another aspx page.<br />Any idea on what I'm doing wrong?<br /><br />If Not IsPostBack Then<br /> Dim objSendingPage As SMSView<br /> 'get the specid from the sending asp page (smsview)<br /> objSendingPage = CType(Context.Handler, SMSView)<br /> glSpecID = objSendingPage.GetSpecID()<br /> gsMSNumber = objSendingPage.GetMS()
