ASP Running And Database Applications

Is it necessary for PWS or IIS mandatory for running ASP pages?

How can we know that in the system IIS or PWS is there??

How can we assign the same text boxes we already created in ASP, the values we get using database manipulations

(e.g) in case of viewing.. one text box we enter...the ID value of employee.

The remaining text boxes we already created, how to assign the values of the corresponding Employee?

It is simple in VB,like Textbox1.text = value..

But in ASP how it is??
