This is because the controls have not been instantiated correctly on the form before they attempt and action. You can either use the components on Form_Activate() or create the component dynamically.

The following is an example of creating a component dynamically and using that control on Form_Load(). Note, you must assign the FTP control as a reference in your VB application before doing this.

Dim WithEvents ftp1 As FTP Private Sub Form_Load() Set ftp1 = New FTP ftp1.RemoteHost = "" ftp1.User = "user" ftp1.Password = "password" ftp1.Logon ftp1.ListDirectory ftp1.Logoff End Sub Private Sub ftp1_DirList(DirEntry As String, FileName As String, IsDir As Boolean, FileSize As Long, FileTime As String) Debug.Print FileName End Sub
