- Remarks
-
This method is called only if you
implemented IwodFtpNotify interface in your application,
and wodFtpDLX.Notification
property has received reference to instance of your
implementation.
FileTransferData notification method is called during file
transfers when LocalPath property (and LocalPath argument in GetFile
or PutFile methods) isn't set, or is set to "" (empty string). In
such cases, GetFile
and PutFile
methods will not open local file for reading/writing, instead they
will call this notification method allowing you to read/write data
from remote file from/to byte array.
Since FileData argument is a byte array, file contents can be
changed in size and in values - you can supply new byte array to
this argument if needed. For example, following code will always
destroy all values in the array, and no matter how large files user
tries to upload (or download), it will always end up with zero sized
file:
- Private Sub
IwodFtpNotify_FileTransferData(ByVal Owner As
wodFtpDLXComLib.IwodFtpDLXCom, FileData() As Byte)
Dim b() As Byte
DirData = b
End Sub
-
-
For downloads: In order to determine exactly how many bytes
are in FileData array, you should calculate it like this (VB
example):
- UBound(FileData) - LBound(FileData) +
1
-
-
Remember that FileData(0) is the first element in the array.
-
-
For uploads: to create new byte array and put some data
inside, so it is transferred to remote side, you can use code
similar to this (VB example):
- Private Sub
IwodFtpNotify_FileTransferData(ByVal Owner As
wodFtpDLXComLib.IwodFtpDLXCom, FileData() As Byte)
Dim a As String
a = "some text"
ReDim FileData(Len(a) - 1)
Dim i As Integer
For i = 0 To Len(a) - 1
FileData(i) = Asc(Mid$(a, i + 1, 1))
Next i
Exit Sub
