I am getting following exception in the code below Exception occurs when closing connection, Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The SqlCommandTimeout is already set 0 as you can see in the code below, When i search records for first time it works fine, but the exceptions start coming second time or third time onwards,.. Protected Overrides Sub DataPortal_Fetch(ByVal criteria As Object) ' Load object data from database. Dim crit As criteria = DirectCast(criteria, criteria) Dim con As New SqlConnection(DB()) // db string is something like //"data source=hurst\SQL2000_SP4;initial catalog=MYDB_OOP_11;Connection Timeout=60;user=asd_user;password=asd_user;" Dim cmd As New SqlCommand con.Open() Try With cmd .Connection = con .CommandType = CommandType.StoredProcedure .CommandTimeout = 0 ' Set up and call appropriate stored procedure. If crit.IsSimpleList Then .CommandText = DBObject & "_info_simple_get" With .Parameters // some code for adding params for SP End With Else .CommandText = DBObject & "_info_get" With .Parameters // adding param for Stored Procedure here End With End If Dim dr As New SafeDataReader(.ExecuteReader) Try Me.Fetch(dr, crit.IsSimpleList) // The fectch function loops for each read of datareader and creates a new object, passing it dr object, each object then reads its column from dr Finally dr.Close() End Try End With Finally con.Close() // I get exception here..on closing.. End Try End Sub Is it something because of improper use of DataReader ? or what is it, I really couldnt figure out, I have Tried using GC.collect() etc , but no use, please help Ahmed

Suppose that there is a window of another process and that window has a CListCtrl on it , i only have the CWnd pointer of the main window that hosts the CListCtrl, i need to add/remove entries in that CListCtrl, ... My approach is that First i need to first get access to the CListCtrl window by getting its handle using BOOL EnumChildWindows( HWND hWndParent, WNDENUMPROC lpEnumFunc, LPARAM lParam ); and once i get this handle i would either try to get CWnd* from it or try sending LVM_XXX messages using CListCtrl handle... I am unsure about if all this would work ... any of you guys , if have any views please share Ahmed
