Returning a dataset

I have an app that calls a web service and passes it a variable "uName"
It first hits my servie level like below.
Then to the businees layer and then the data layer.  The data layer calls a stored procedure and returns the data everything works.
When the Return dataset goes back to the business layer the ds is empty.
<WebMethod()> _
    Public Function GetCustInfo(ByVal uName As String) As DataSet
        Return objBusiness.GetCustInfo(uName)
    End Function
 
--------------------------------------------------
Data Layer
Public Function GetCustInfo(ByVal uName As String) As DataSet
        Dim db As dbAccess = New dbAccess
        Dim param As SqlParameter
        Dim parameters As ArrayList = New ArrayList
        Dim ds As DataSet
 
        param = New SqlParameter("@uName", uName)
        parameters.Add(param)
 
        ds = db.RunSPSQLServer("spGetCustInfo", parameters)
        ds.Tables(0).TableName = "CustInfo"
 
        Return ds
 
    End Function

Hi triplebd69;

Place a break point at this line in the code, "ds.Tables(0).TableName = "CustInfo"", make sure that, db.RunSPSQLServer("spGetCustInfo", parameters), returned a data set and that it has a table in it with data.

In the service layer I needed to change the code to like below.

Dim ds As DataSet = objDataObject.GetCustInfo(uName)
Return ds
