The connection string will look like this in the code: connection->ConnectionString = "User ID=sa; Password=; Data Source=(local); Initial Catalog=DCV_DB;"; or connection->ConnectionString = "Persist Security Info=False;Integrated Security=SSPI;" "Data Source=(local); Initial Catalog=DCV_DB;"; The connection string for the Oracle managed provider is very similar to the SQL Server managed provider, whereas the OLE DB and ODBC managed providers always add an additional clause: for OLE DB, the Provider clause, and for ODBC, the Driver clause. For example: //OLE DB Connection string connection->ConnectionString = "Provider=SQLOLEDB; Data Source=(local); Initial Catalog=DCV_DB; " "User ID=sa; Password=;"; and // ODBC Connection string connection->ConnectionString = "Driver={SQL Server}; Data Source=(local); Initial Catalog=DCV_DB; " "User ID=sa; Password=;"; vb.net ean 13 reader .NET EAN - 13 Barcode Reader for C#, VB .

Whereas the messaging layer provides total control over the messages flowing around in your application, the service model layer is a higher-level abstraction layer that allows you to influence the messaging through object-oriented programming principles. This is really where the WCF team was able to reach its design goals. The service model layer offers an easy-to-use API with classes, methods, attributes, and configuration to build connected applications. Behaviors are the most important concept in this regard. You can apply multiple behaviors on the client and service sides. Behaviors don t influence the contract in any way; in other words, consumers of services don t know the details about the behavior of the service. Behaviors influence the conversion from messages to .NET types, instancing, throttling, concurrency, and error handling. Up until now in this book, we have covered the generic concepts of the entire API; the rest of this chapter is focused on the service model layer. This is the layer you will use the most. You open and close the database in virtually the same way as you do a file, except the Open() method doesn t have any parameters: connection->Open(); connection->Close(); You need to pay attention to the try statement. ADO.NET commands can abort almost anywhere, so it is always a good thing to enclose your ADO.NET logic within a try clause and capture any exceptions by catching SQLException (OleDbException, OdbcException, or OracleException). It is also possible for ADO.NET to abort with the database still open. (Probably not in this example, but I felt having the correct code right from the beginning would make things clearer.) Therefore, it is a good idea to place your Close() method within a finally clause so that it will always be executed. vb.net ean 13 reader VB .
