Re: how to make cookies into an array?

Tim, don't become angry (i'm learning), but it still doesn't work ...
If i do what you wrote here, i get an error with the line:
oneCookie = New HttpCookie
the error is: "overload resolution failed because no accessible 'new'
accepts this number of arguments"
so i tried this (and the error is gone): oneCookie = New HttpCookie("ok")
the whole code is:
Dim allCookies As New Generic.Dictionary(Of String, HttpCookie)
Dim i As Integer
Dim oneCookie As HttpCookie
For i = 1 To 5
oneCookie = New HttpCookie("ok")
oneCookie.Value = i
allCookies.Add("test" & i, oneCookie)
Next
But now, how can i retrieve the cookies? I did:
Dim allCookies As New Generic.Dictionary(Of String, HttpCookie)
Dim i As Integer
Dim cc(5) As String
Dim retCookie As HttpCookie
For i = 1 To 5
retCookie = allCookies("test" & i)
cc(i) = retCookie.Value
Response.Write(cc(i) & " ")
Next
And the error is now: "The given key was not present in the dictionary"
Can you help me a last time? Thanks

But you are trying to convert "test1" to a cookie. That is a string, not a
cookie. You must specifically create an instance of HttpCookie, fill in
its constructor or fields as needed, and then store it. I haven't used
that object myself, but the code would be something like this.
Dim allCookies As Generic.Dictionary(Of String, HttpCookie)
Dim oneCookie As HttpCookie
Dim i As Integer
For counter = 1 To 5
oneCookie = New HttpCookie
' !!! Fill in all of oneCookie's fields here, then...
allCookies.Add("test" & counter, oneCookie)
Next counter

Hi,
thanks for replying ...
I tried this (it must be a loop because i never don't know in advance
how
many cookies i need)
But i get the error: "value of type string cannot be converted to
system.web.httpcookie"
How can i give the value of the cookie?
Thanks
Dim allCookies As Generic.Dictionary(Of String, HttpCookie)
Dim i As Integer
Dim cc(5) As String
For i = 1 To 5
allCookies.Add(cc(i), "test" & i)
Next

If you are using VB2005, you can switch to one of the Generic
collections that includes a key so that you can look up the cookie by
name.
Dim allCookies As Generic.Dictionary(Of String, HttpCookie)
Add new cookies to the dictionary this way:
allCookies.Add(cookieName, theCookieItself)
Access the cookie this way:
theRetrievedCookie = allCookies(cookieName)

Hi,
I need several cookies depending of an variable (x), so i defined a
HttpCookie() as an array.
My problems:
1)I get the error: Object reference not set to an instance of an
object.
2)My second question is: how to request those cookies, because there
is no
name?
Thanks
André
I did:
x=5
Dim cok(x) As New HttpCookie 'can't give a name to the cookie
....
for k=1 to x
cok(k).Value = "cookie" & k
Response.Cookies.Add(cok(k))
next
-----------------------------------
recovering the cookies?
for i=1 to x
cok(i) = Request.Cookies("??")
next
.
