Error during Synchronization

While synchronizing data between the PDA and MS SQL Server database, using Active Sync connection, the sync process fails at times and displays an empty error message box and occasionally it shows the following exception:

Error During Synchronization:

A native exception occurred.

ExceptionCode:0xc0000005

ExceptionAddress:0x01627b28

Reading: 0x1e000000

OK to terminate

CANCEL to debug

Moreover the .SDF file on the PDA gets corrupted. The ActiveSync connection drops as soon as the sync process fails. Later when the .SDF file is deleted and restored the synchronization is successful.

Note: The replication monitor in the SQL Server indicates that the synchronization was successful even when the above error occurs.

========================================================
** Sample code where the app crashes we encounter the issue:

Public Sub Synchronize (ByVal vShowMessage As Boolean)

Dim ce As SqlCeReplication = Nothing

Try

ce = New SqlCeReplication

'Set Internet properties.

ce.InternetUrl = vInternetURL ' "http://xx.xx.xx.xx/SQLCE/sscesa20.dll"

'Set Publisher properties.

ce.Publisher = vPublisher

ce.PublisherLogin = vPublisherLogin '"sa"

ce.PublisherPassword = vPublisherPassword '"xxxxxx"

ce.PublisherSecurityMode = SecurityType.DBAuthentication

ce.PublisherNetwork = NetworkType.DefaultNetwork

ce.PublisherDatabase = vPublisherDatabase

ce.Publication = vPub_Name

'Set Subscriber properties.

ce.Subscriber = vSub_Name

ce.SubscriberConnectionString = "Data Source=" & DB_PATH & vDatabase_Name

If File.Exists(DB_PATH & vDatabase_Name) = False Then

ce.AddSubscription(AddOption.CreateDatabase)

End If

ce.Synchronize()

Catch ex As SqlCeException

If vShowMessage = True Then

MsgBox(ex.Message)

End If

Throw ex

Catch ex1 As Exception

If vShowMessage = True Then

MsgBox(ex1.Message)

End If

Throw ex1

Finally

ce = Nothing

End Try

End Sub
