Please help, Im stuck and am going crazy with this simple problem.
My code runs a function from a class and returns a dataset of records from the sqlserver.
All i want to do is work through the dataset and for each record, insert it into a listview.
Please can anyone spot the problem with this code:
Dim ds As New DataSet()
Dim dt As New DataTable()
Dim dr As DataRow()
ds = m_BO.admin_GetUsers()
dt = ds.Tables("Users")
For Each dr In dt.Rows
ListView1.Items.Add(Convert.ToString(dr.GetValue(2)))
Next
The error occurs on the For each line:
An unhandled exception of type 'System.InvalidCastException' occurred
Additional information: Specified cast is not valid.
There is definitely data there, I am sure of that at least.
Please please help before I go crazy
