WFS: GetVolumeName: Only up to 12 characters?

GreatOm · **Joined:** Fri Sep 30, 2005 8:25 am **Posts:** 97

Hi all!

I just tried to get the name of a Volume which works fine using the Windows Functionality Suite 2.6.
I use FileProcessing.GetVolumeName, which uses declares for GetVolumeInformationW or GetVolumeInformationA.

Unfortunately there are volumes with names longer than 12 characters and I get only the first 12 chars of that name.

Any clues how to solve this problem?

TIA,

GreatOm

That's very odd; the GetVolumeInformation function should handle volume labels up to 259 characters long. I tested the WFS implementation just now and it worked for me, even after changing the volume label to a very long one. What version of Windows are you testing on and have you made any changes to the FileProcessing.GetVolumeName function? How are you handling the returned string?

Hm... I did test against a not Windows based SMB server. So I think this issue may be server related. In Explorer I see the full volume name though...

Nope.

Thanks for your reply. No I have a clue where to investigate.

Funny...

Now I did a test against a Windows 7 based share and I get no volume name at all...
I id connect a network drive and In Explorer on my Windows 2008r2 client I see the Volume
"ICC-Profiles (\\MACHINENAME) (V:)"

I verified aslo that the code is the same as in WFS: FileProcessing.GetVolumeName and the Name is just empty.

Another thing:
I added this debug statement

#if DebugBuild
  System.Log System.LogLevelError,"Drive: "+ volumeF.Name + ", Name: " + volNameStr
#endif

and it gives me following error in the Event Viewer:

Quote:

The description for Event ID 1000 from source Microsoft-Windows-User Profiles General cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Drive: V:, Name:

the message resource is present but the message is not found in the string/message table

Very strange. I try some more debugging.
