there could be two type of problem here i can see !

First

template <class D>SLList<D> SLList<D>&::operator+(SLList<D> ob2) {
return this+obj2;
}

Return type should be Reference to...

template <class D>SLList<D> SLList<D>::operator+(SLList<D> ob2) { return *this;}

for this funtion u have to traverse all the lists and add them up !

this return status just returning the one...

you can save the Body and relavent information to database .

after you can retrieve that information whenver u need.

wherever you wanted to present.

it is very simple with asp net .

Put a File Upload Button in yours controls.

suppose there is a button on urs controlls READ.

on the event handler Read on click event use this Code.
...

Sub Page_Load(s As Object, e As EventArgs)
Dim DayNum As Integer
DayNum = 3
Session["DayNum"] = DayNum;

End Sub

Sub Btn_Click(s As Object, e As EventArgs)
...

Check yours connection string it must have password.

from web.config.

change the connection string without password.

i have the same problem in last days . i have tried the same solution which Yousaf uddin suggested...

you can make access to different pages by using Session.

every user has its own role. so in database define Roles for every user.

like
there would be three fields ..

User name , Password...
