[RESOLVED] 'System.Data.SqlClient.SqlException'

[Golfreak]

hey guys

just wondering if anyone can help. I'm getting this error:

An unhandled exception of type [B]System.Data.SqlClient.SqlException [/B] occurred in system.data.dll
 
Additional information: System error.

and it occurs in this Sub: (in red)

Public Sub UpdateCombo()
 
        Dim RSAllCategories As SqlClient.SqlDataReader
 
        SqlUpdateCommand1.CommandText = "Exec ProblemCategoryList"
        [COLOR=Red]RSAllCategories = SqlUpdateCommand1.ExecuteReader()[/COLOR]
       
        Do Until RSAllCategories.IsClosed
 
            cmbSelect.Items.Add(RSAllCategories.GetValue("ProblemCategory").Value)
            RSAllCategories.NextResult()
 
        Loop
 
    End Sub

whats wrong with the code?
