I am add call method CDInfo(NERO_READ_CD_TEXT) and event handler OnDoneCDInfo in exemple Nero SDK.

Private Sub Form_Initialize()
Set nero = New nero
Dim drives As INeroDrives
Set drives = nero.GetDrives(NERO_MEDIA_CDR)

For myIndex = 0 To drives.Count - 1
AvailableDevices.AddItem drives(myIndex).DeviceName, myIndex
Next
AvailableDevices.ListIndex = 0
Dim drives As INeroDrives
Set drives = nero.GetDrives(NERO_MEDIA_CDR)
Set drive = drives(AvailableDevices.ListIndex)
ErrHandler:
Exit Sub
End Sub

----------------------------------------------------------------------

Private Sub Command1_Click()
drive.CDInfo (NERO_READ_CD_TEXT)
End Sub
-------------------------------------------------------------------------------
Private Sub drive_OnDoneCDInfo(ByVal pCDInfo As NEROLib.INeroCDInfo)
MsgBox ("Work")
End Sub

Wot wrong????

Here is a silly question... Do you ever click Command1 button?

What Nero version are you using?

Yes I am pressing command button!!!!
To me not up to jokes
Version Nero Burning ROM 6.0.0.15

Could you please upgrade to a newer version than 6.0.0.15. This might solve your problem. There were some issues in the earlier versions.

Sub ImportIsoTrack(TrackNumber As Long, dwFlags As NERO_IMPORT_ISO_TRACK_FLAGS)

Is exists TrackNumber parameter value, having specified which,
I can mport last session, not knowing number of last track?
-1?

No, you must specify a valid session number to import. -1 will not do.

1. Whether it is possible to learn number of last session, not call a method CDInfo

2.May I upgrade only NeroCom.dll?

No. Doing a cd info is the only way to find out the number of previous sessions.

No. By upgrading your Nero installation, you will get an upgrade to NeroCOM as well.
