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")

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

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.

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!!!

Hi all,
I need help,I am entering datetime in dd-mm-yyyy format by TextBox1.Text but i need only "mm" is to enter and retrive from sqlserver database.
How it possible?
In Vb.net month(colname)='"&month(TextBopx1.Text)"'

You could try and seperate the date format out by using split function, not sure though
|
|
|
|
|
The text property of your textbox is a string type. You cannot get the month only from a string using a month() function. You can split the string on the '-' character and the retrieve the month from the string array..
<br />
Dim sDateParts as String() = TextBox1.Text.Split('-')<br />
Dim sMonth as String = String.Empty<br />
<br />
if (sDateParts.Length = 3)<br />
sMonth = sDateParts(1)<br />
|
|
|
|
|
You could always use DateTime.Parse(TextBox1.Text).Month;. I know it's C#, but you can translate this to VB.NET yourself - it's not that hard.
