cannot refer to an instance member of a class from within a shared
Hi
I am trying to get an AJAX call working from asp.net working with VB. However, I am getting the error as per the above with when I am trying to pass an Id to a new method.
the code I am using is
if I make the method a shared method this then causes the same error on my other methods.
In the method of WriteToExcel() if I make this a shared sub then Server.MapPath has this same issue too, along with other methods that are referred to too such as PassToErrorHandler.
And in the GetValidatedPayments method,
using this line
causes the same error on Master.
Any and all help very much appreciated.
Thanks
