Re: How to call a Sub function from .ASPX file ?

Thanks, Tom. I did try it last time and it worked when I put all the files
in an application using Visual Studio.NET. My requirement now is to create
a single .ASPX file containing VB.NET language, JavaScript language and
HTML, and call a function from this .ASPX file without using Visual
Studio.NET to create an application.
