Begins the process of changing the currently logged-in user to the specified user without disconnecting from the FTP server. Don't forget to call EndChangeUser!
'Usage
Dim instance As AsyncFtpClient
Dim userName As String
Dim password As String
Dim callback As AsyncCallback
Dim state As Object
Dim value As IAsyncResult
value = instance.BeginChangeUser(userName, password, callback, state)
Parameters
userName
The username with which to relogin into the FTP server.
password
The password with which to relogin into the FTP server.
callback
Callback method to be called when the asynchronous operation is completed.
state
An object containing state information for this operation.
Return Value
An System.IAsyncResult representing the status of the asynchronous operation.
Remarks
When using a callback, the System.IAsyncResult is provided as a parameter. You should call EndChangeUser in that callback. When NOT providing a callback, you should keep the returned IAsyncResult and call EndChangeUser with it when ready to complete. In this later case, the call to EndChangeUser may block until the operation completes.
