Hello,

 

I am tring to return a employee object to my GUI Page from a dataaccess page. Every thing seems to do fine until the function try's to return the employee object from the Ordional Postion of (0) from the EmployeeList Innerlist. I am getting stuck on the GET and the Return CType(Me.Item(index), Employee) . Wehn i step into the code It just goes back and forth like it is stuck or something. Like a broken record.. And when i just run the application i get an error message that there is a overflow error.

 

Can someone please look at this and let me know where i need to make chages?

 

I can post all of the code if i need to..

 

 

Thanks,

Erik,..

 

 

If you will look below; this is where i am tring to return the employee object

 

Default Public ReadOnly Property Item(ByVal index As Int32) As Employee

Get < ******Stuck here********

Return CType(Me.Item(index), Employee) < ***** AND HERE

Dim EmpAss As New EmployeeAccess

ddl.DataSource = EmpAss.PopEmployee(2)

ddl.DataBind()

Public Function PopEmployee(ByVal Empid As Int32) As Employee

 

PopEmployee = GenericDataAccess("Employee_Byid", "@Employeeid", Empid)

In the code snippet

Default Public ReadOnly Property Item(ByVal index As Int32) As Employee
Get < ******Stuck here********
Return CType(Me.Item(index), Employee) < ***** AND HERE

you are calling the function Item(Int32) from within itself, hence the reason it is just recursing...

You probably want to return the contents of innerlist like

Default Public ReadOnly Property Item(ByVal index As Int32) As Employee
Get < ******Stuck here********
Return CType(Me.InnerList(index), Employee) < ***** AND HERE
