Hi
My code complies the following line:
Session("passed") = 1
but puts wiggly error line under the second Session("passed") in the
following expression:
Session("passed") = Session("passed") + 1
Why?
Thanks
Dee.
Session("passed") = Session("passed") + 1
Session("passed") = Session("passed") + 1
13  1875 
Because Session("passed") is a string.
Try casting to Int, and then adding 1 to it.

Session("whatever") is not a string, it's an "object".
You can't cast a string to an int (you have to "parse" it),
but you can cast an object to an int (if it really *is* an int).
So your solution *does* work...

Hello, Hans.
While the Session object is an object ( of course ),
its *content* can be a string, as in this particular case
....where the 1 in Session("passed") = 1 is a string, not an object.
This works, for example :
Session("passed") = 1
Dim yNumber as String = Session("passed")
Dim jNumber as Integer = Int32.Parse(yNumber)
Dim wNumber as Integer = jNumber + jNumber
lblMessage.Text = wNumber.ToString()
You're right about the use of "casting", though.
That was a bit sloppy on my part.
I should have used "Convert.ToInt32" or "Parse".
Int32.Parse() is what Convert.ToInt32() calls, anyway, isn't it ?

Actually I think you'll find it's an int32 not a string, if you do:
Session("test") = 1
Dim a As String = Session("test").GetType.ToString
You'll see that a is System.Int32

Question for you :
How does Session("passed") = 1
get converted from Int32 to String in
Dim yNumber as String = Session("passed")
Shouldn't that cause an "incorrect type" error ?

Hmm, I think .net is just being friendly and automatically casting the int32
to a string for you. That's my guess anyway.
you get the same thing if you do:
Dim a As Int32 = 1
Dim b As String = a
