How do I read/write to the boot sector of a floppy or hard disk in VB
4.0? I basically need to find out what the volume label is and
possibly change it. I checked C++ and couldn't find a way either.
Unless someone knows a way.
Thanx,
Eric Schweda

I may be grasping at straws, but the Volume Label is not stored in the
Boot sector.  It is in a directory entry of the root.  Look at the Dir
function in the online help.  Now if you are talking about the Volume
Serial Number, That probably involves using some API to get it.

Try this:

        VolumeName$ = Dir$("C:*.*",ATTR_VOLUME)

where the constant ATTR_VOLUME = 8.

The volume name is stored as other file names but with the special
attribute of 8.

Hope this helps.

The user will love that when all the programs which check for a particular
vsn suddenly quit working.

Does that mean that you DON'T know how to do it?

Have I missed the point? What's wrong with the Dir function in VB?
Mark Dootson

Let's try something useful folks...

Declare Function GetVolumeInformation Lib "kernel32" Alias
"GetVolumeInformationA" (ByVal lpRootPathName As String, ByVal
lpVolumeNameBuffer As String, ByVal nVolumeNameSize As Long,
lpVolumeSerialNumber As Long, lpMaximumComponentLength As Long,
lpFileSystemFlags As Long, ByVal lpFileSystemNameBuffer As String, ByVal
nFileSystemNameSize As Long) As Long

x=shell("vol [drive:] > c:\vol.txt")
wait 1 second
then read in vol.txt to your variables for parsing.

That's the quickest way to go for me, 'cause I don't have to research it.  
There probably is a call, lord knows what it'd be called mabey GetVolInfo?

To read Volume Label use Dir function
To write Volume Label (in Win3.11 /95), put dos LABEL command in batch
file, shell batch file passing new label as a parameter.

Its my kludge and I'll try it if I want to.
