Nope, IIS 5.1 works well

This is not clear. Please explain it more. Also some sample code would be helpful

Ok, Let's go... Code: the first moment, this code is called in load method **************************************** dim ds as dataset ds = obj.list ' the method return a dataset of products listbox1.DataSource = ds listbox1.DataTextField = "Name" listbox1.DataValueField = "ID" listbox1.DataBind() Session("ds") = ds **************************************** the second moment, this code is called in detail method, when select a item in listbox1 **************************************** ds = Session("ds") Dim dr() As DataRow = ds.Tables(0).Select("ID = " & listbox1.SelectedValue) txtName.Text = dr(0)("Name") txtDescript.Text = dr(0)("Descript") lblNameSystem.Text = dr(0)("NameSystem") **************************************** The Error: Object not istance. I identified that error is ocurring in Session("ds"), but is ocurring only IIS 5.1., in debug it isn't ocurrign. Did you understand me? Thanks,

I guess you haven't declared the dataset again in the event. Or you may consider declaring it outside the pageload. Also the page_load code should be put inside If not isPostBack block, else the dataset will be created and filled to session each time page posts back.

I hope casting required when assin session dataset to local object dataset. I just modified your code as follows the second moment, this code is called in detail method, when select a item in listbox1 **************************************** ds = DirectCast(Session("ds"), Dataset) Dim dr() As DataRow = ds.Tables(0).Select("ID = " & listbox1.SelectedValue) txtName.Text = dr(0)("Name") txtDescript.Text = dr(0)("Descript") lblNameSystem.Text = dr(0)("NameSystem") ****************************************

Ok, I'm going to see it. Thanks

Hi, The problem is continuing!!! I don't know like solve it. Thanks,

[Sankar Komma]

can you provide at what level(i.e line) the error is getting and what error. In c# it is compilation error if we don't cast session dataset.

I created a new page and used simple code testing session with string ("its my text"). The error ocurred. I'm thinking to myself that this error is in IIS!! Because it isn't ocurring in deployment!!!

People, I'm caming back because session in my app isn't working correctly. I did a simple code: in load method : session("test")= "hello world" in click button response.write (session("test")) What can I do?

Unlikely. While it must be tempting for you to think that your code is better than Microsoft's, it's probably pretty unlikely. I would suspect that your problem has more to do with you using the wrong SessionState type or just assigning it in the wrong place.

Deja View - the feeling that you've seen this post before.

Hi Pete, I've already discovered the error. The error was caused because name resolution in domain. My code was correct and IIS too, but the network's configuration was wrong. Thanks my friend!!! :-D
