Dart.PowerTCP.Ftp.Invoke
[Visual Basic]
Public Class Invoke [C#]
public class Invoke [C++]
public __gc class Invoke [C++/CLI]
public ref class Invoke Many Internet protocols are based on a request/reply system, where the client sends a request, and the server sends at least one reply. This continues lock-step until communication is complete. The Invoke object encapsulates these request/reply pairs.
In PowerTCP commands are often sent using the Object.Invoke or Object.BeginInvoke methods. When a command is sent an Invoke object is returned describing both the request and response. The response is encapsulated by the Invoke.Response property, which allows easy access to the raw and parsed response from the server. The request is represented by the Invoke.Request property, a string containing the request sent.
The following example demonstrates using Invoke to send a command.
[Visual Basic]
' Set server and user properties. This will allow us to call other
' Ftp Component methods with the log in taking place "behind the scenes"
Ftp1.Server = "MyFTPServer"
Ftp1.Username = "blah"
Ftp1.Password = "mypass"
' Invoke a command
Dim invoke as Dart.PowerTCP.Ftp.Invoke
Try
invoke = Ftp1.Invoke(FtpCommand.NoOp)
Catch ex as Exception
Debug.WriteLine("Error: " + ex.Message)
Exit Sub
End Try
' Success
Debug.WriteLine("Request/Response messages: " + invoke.ToString())
[C#]
// Set server and user properties. This will allow us to call other
// Ftp Component methods with the log in taking place "behind the scenes"
ftp1.Server = "MyFTPServer";
ftp1.Username = "blah";
ftp1.Password = "mypass";
// Invoke a command
Dart.PowerTCP.Ftp.Invoke invoke;
try
{
invoke = ftp1.Invoke(Dart.PowerTCP.Ftp.FtpCommand.NoOp);
}
catch (Exception ex)
{
Debug.WriteLine("Error: " + ex.ToString());
return;
}
// Success
Debug.WriteLine("Request/Response messages: "
+ invoke.ToString());
