'Declaration
 
Public Function BeginChangeToParentFolder( _
   ByVal callback As AsyncCallback, _
   ByVal state As Object _
) As IAsyncResult

'Usage
 
Dim instance As AsyncFtpClient
Dim callback As AsyncCallback
Dim state As Object
Dim value As IAsyncResult
 
value = instance.BeginChangeToParentFolder(callback, state)

public IAsyncResult BeginChangeToParentFolder( 
   AsyncCallback callback,
   object state
)

Parameters

callback

Callback method to be called when the asynchronous operation is completed.

state

An object containing state information for this operation.

Return Value

The FTP server's current working folder is used by the FTP server as the base folder from which to perform file operations such as obtaining folder contents, receiving, sending and deleting files, changing the current folder, etc. It can be retrieved via the BeginGetCurrentFolder%M:Xceed.Ftp.AsyncFtpClient.EndGetCurrentFolder(System.IAsyncResult)% methods.

When using a callback, the System.IAsyncResult is provided as a parameter. You should call EndChangeToParentFolder in that callback. When NOT providing a callback, you should keep the returned IAsyncResult and call EndChangeToParentFolder with it when ready to complete. In this later case, the call to EndChangeToParentFolder may block until the operation completes.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
