To serialize, iterate over the linked list. Maintain a counter while you are iterating. Save each list item in the database along with the counter. To deserialize, query the database for your list information, sorted by counter. Iterate over the list information, appending each record as a node to the end of your list. -- modified at 23:57 Monday 10th July, 2006

I am using VS2003. I don't have VS2005. I am rewriting in VB.Net now so I can use "GetVolumeInformation". You know VB?? I am hitting another brickwall in VB. One of the parameters used by "GetVolumeInformation" is declared as Dim driveLabel As String = Space(200) This string has length of 200 (driveLabel.length = 200)even if the useful part of the string is only 5 chars long (say "Tommy ... " ) Do you know how I can extract the useful part of "driveLabel" in VB?? I might ask this question on the VB MessageBoard
