can't create form in code-behind file

[Dan]

Hi,

I deleted the form created by VWD in the aspx file (because i know there may
only be one server-form) and I tried to create in the code-behind file a
form like:
dim t as form

but it doesn't appear in the dropdown list of VWD.

Why is it not possible to create a form directley in vb.net?

Thanks
Dab
