Hallo Jürgen,
kurz noch ein Beispiel mit API:
Const FTP\_TRANSFER\_TYPE\_UNKNOWN = &H0
Const FTP\_TRANSFER\_TYPE\_ASCII = &H1
Const FTP\_TRANSFER\_TYPE\_BINARY = &H2
Const INTERNET\_DEFAULT\_FTP\_PORT = 21 ' default for FTP servers
Const INTERNET\_SERVICE\_FTP = 1
Const INTERNET\_FLAG\_PASSIVE = &H8000000 ' used for FTP connections
Const INTERNET\_OPEN\_TYPE\_PRECONFIG = 0 ' use registry configuration
Const INTERNET\_OPEN\_TYPE\_DIRECT = 1 ' direct to net
Const INTERNET\_OPEN\_TYPE\_PROXY = 3 ' via named proxy
Const INTERNET\_OPEN\_TYPE\_PRECONFIG\_WITH\_NO\_AUTOPROXY = 4 ' prevent using java/script/INS
Const MAX\_PATH = 260
Private Type FILETIME
dwLowDateTime As Long
dwHighDateTime As Long

ftLastWriteTime As FILETIME
nFileSizeHigh As Long
nFileSizeLow As Long
dwReserved0 As Long

Das läuft auch mit der Standardversion von VB6, aber ganz ohne OCX kommt auch dieses Programm nicht aus.
