LoadProperties Method
Retrieves all values stored for the synchronization properties, and then populates the SqlCeReplication class properties with these saved values.
Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in System.Data.SqlServerCe.dll)
Syntax
'Declaration
Public Function LoadProperties As Boolean
'Usage
Dim instance As SqlCeReplication
Dim returnValue As Boolean
returnValue = instance.LoadProperties()
public bool LoadProperties()
public:
bool LoadProperties()
member LoadProperties : unit -> bool
public function LoadProperties() : boolean
Return Value
Type: System. . :: . .Boolean
Remarks
For the LoadProperties function to succeed, you must provide all of the SqlCeReplication object properties unless the database specified in the SubscriberConnectionString has only one subscription. If the database subscribes to only one publication, you can omit the following properties:
If LoadProperties is called without setting these properties, and more than one subscription exists in the database, an error is raised for each subscription in the database. Each error in the collection contains the string parameters of the Publisher, Publication, and PublisherDatabase properties for each subscription in the database.
When SaveProperties is called, the values for the password properties are stored in the database. These values are automatically encrypted with the unique device hardware key. Therefore, if you create a subscription profile on one device (or a server), and then copy the database to a new device, LoadProperties will fail to retrieve the password from the profile. You can provide the correct password manually and then call SaveProperties again to persist the profile on the new device.
Examples
The following example shows how to use the LoadProperties method.
Try
'
'NOTE: when possible, prompt users to enter security
'credentials at runtime. If you store credentials in a file,
'you must secure the file to prevent unauthorized access.
'
Dim repl As New SqlCeReplication()
repl.SubscriberConnectionString = "Data Source='Test.sdf'; Pwd='<enterStrongPassword>'"
repl.LoadProperties()
repl.Synchronize()
Catch
' Handle errors here
End Try
try
{
//NOTE: when possible, prompt users to enter security
//credentials at runtime. If you store credentials in a file,
//you must secure the file to prevent unauthorized access.
//
SqlCeReplication repl = new SqlCeReplication();
repl.SubscriberConnectionString = "Data Source='Test.sdf'; Pwd='<enterStrongPassword>'";
repl.LoadProperties();
repl.Synchronize();
}
catch (SqlCeException)
{
// Handle errors here
}
