DotNetClass [System.IO.DriveInfo]

[LoneRobot]

hi mike

try

SomeDriveInfo = DotNetobject "System.IO.DriveInfo" "c:\\"
-- result is in bytes so divide a few times to get GB
GBleft = (((SomeDriveInfo.AvailableFreeSpace/1024)/1024)/1024)
if GBleft > 5 then print "enough space" else print "medic!"

Thanks Pete, much appreciated!
However, a problem, which I can't think of a workaround is, if the path is a UNC path, then it doesn't work!

All these are vaild...

DriveOutput = DotNetobject "System.IO.DriveInfo" "C"
DriveOutput = DotNetobject "System.IO.DriveInfo" "C:"
DriveOutput = DotNetobject "System.IO.DriveInfo" "C:\\"

But,

DriveOutput = DotNetobject "System.IO.DriveInfo" "\\myserver\\"

fails :-(

According to the error ("-- Runtime error: dotNet runtime exception: Object must be a root directory ("C:\") or a drive letter ("C").") you must point to a drive letter, so unmapped unc paths will be invalid.

hi mike, could you map a network path and use that letter instead?

[MikeOwen]

Hence my problem..!
Looks like a lookup table for UNC paths against drive letters is the only option :-(

or some more storage!

Have a look at this : http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/63c0b94a-8e53-46f8-b46e-c2e8c9f4686f

You can write a custom class and you've solved your problem. Cheers

Or you download my KClasses and do something like this :D

dotnet.loadassembly @"C:\KClasses.dll"

dnGet=dotnetObject "KClasses.DnGetDiskFreeSpaceEx"
dnGet.dnGetDiskFreeSpace @"\\yourserver\shared\"
print (((dnGet.freeBytes / 1024) / 1024) / 1024)

Values are returned in Long. Cheers!

Thanks very much Kameleon, much appreciated.
However, running this code;

dotnet.loadassembly @"C:\KClasses.dll"
dnGet=dotnetObject "KClasses.DnGetDiskFreeSpaceEx"
dnGet.dnGetDiskFreeSpace @"\\myserver"
GBleft = (((dnGet.freeBytes/1024)/1024)/1024)

results in:

dotNetObject:System.Reflection.Assembly
dotNetObject:KClasses.dnGetDiskFreeSpaceEx
false
0L

But myserver has 7GB free..! Does this class work on a x64bit XP OS with x64bit Max?

BTW, what did you use to compile the dll with? VS2008 Express?

Thanks,

Mike

you have to specify the actual resource.. and make sure it exists.

e.g.


-- correct
dnGet.dnGetDiskFreeSpace @"c:"
false
GBleft = (((dnGet.freeBytes/1024)/1024)/1024)
17L

-- wrong
dnGet.dnGetDiskFreeSpace @"\\zb-test\"
false
GBleft = (((dnGet.freeBytes/1024)/1024)/1024)
17L -- bogus value left over from the previous call

-- correct
dnGet.dnGetDiskFreeSpace @"\\zb-test\Public"
false
GBleft = (((dnGet.freeBytes/1024)/1024)/1024)
489L -- that's better

[Kameleon]

I've updated my example, my bad sorry :D Just go by what ZBoxx said :)

Yeah, I've used VS2008 Express. Cheers!

Hi All,

I have just found out that due to security permissions, you can't put the "KClasses.dll" onto a network server, which is annoying....!

dotnet.loadassembly @"\\\\myserver\\newfolder\\KClasses.dll"
dnGet=dotnetObject "KClasses.DnGetDiskFreeSpaceEx"
dnGet.dnGetDiskFreeSpace @"\\myserver\newfolder"
GBleft = (((dnGet.freeBytes/1024)/1024)/1024)
if GBleft > 10 then print "enough space" else print "medic!"

Causes the error:

-- Runtime error: dotNet runtime exception: System.Security.Permissions.SecurityPermission

Do you know of a workaround, apart from copying the dll to say, the root of whatever version of 3dsMax I am using?

Thanks,
Mike

[Kameleon]

One thing that I did was to check if the KClasses.dll file was in the network folder and if it was, copy it to the local scripts folder and load the assembly from there.

[MikeOwen]

Thanks.
I have now taken this approach and its working at the moment.
Mike
