Notification Property

wodFtpDLX ActiveX Control - Notification Property (wodFtpDLXCom)

Description

Fast notification interface to use instead of events.

Property type

An IwodFtpNotify object.

Syntax

[Set] object.Notification [= IwodFtpNotify]

The Notification Property syntax has these parts:

Part	Description
object	An expression evaluating to an object of type wodFtpDLXCom.
IwodFtpNotify	An IwodFtpNotify object. Reference to object that implements this interface.

Remarks

Available only in Component (DLL, windowless) version!

Notification property holds reference to IwodFtpNotify interface that can be implemented by your application. When this property is set, and contains such a reference, wodFtpDLXCom will call your method implementations instead of firing events. More information on how this works can be found here.

For example, instead of having this in your code (VB example):

Private Sub Ftp1_Connected(ByVal ErrorCode As Long, ByVal ErrorText As String)

End Sub

you will have this:

Private Sub IwodFtpNotify_Connected(ByVal Owner As wodFtpDLXComLib.IwodFtpDLXCom, ByVal ErrorCode As Long, ByVal ErrorText As String)

End Sub

pretty much the same - except notification method has one more argument - Owner, which holds reference to wodFtpDLX instance that called this method.

In VB, to implement IwodFtpNotify interface, you need code like this:

- at the top of the code, in <general> section, put this:

Dim Ftp As wodFtpDLXCom
Implements IwodFtpNotify

- in Form_Load (or where you initialize new instance of wodFtpDLX) do this:

Set Ftp = New wodFtpDLXCom
Set Ftp.Notification = Me
Ftp.Protocol = FTP
Ftp.Timeout = 30
Ftp.Connect
...

You can notice that when we declared Ftp, we did not use WithEvents keyword - it is not needed anymore, because events will not be fired anymore. Notification methods we implement will be called instead!
