[Closed] Remove drive letter with C# in maxscript

What is your goal here? Messing with mount points sounds a tad bit invasive for a max plugin to do on a user’s system, not to mention it likely requires administrator rigths. If it’s a temporary drive letter you need, have you considered using virtual drives instead? If things go wrong, at least they won’t persist through a reboot.

Removing a virtual drive would be very easy, too:

fn RemoveDriveLetter driveLetter = ( hiddenDOSCommand ("subst " + driveLetter[1] + ": /D") )

In fact Iwant to use this for my personal computer only, so nobody will suffer I do it manually, but wanted to automate.

global DriveAssembly
fn CreateDriveAssembly =
(
	source  = ""
	source += "using System;
"
	source += "using System.Runtime.InteropServices;
"
	source += "public class DriveOps
"
	source += "{
"
	source += "    [DllImport(\"kernel32.dll\", CharSet = CharSet.Auto, SetLastError = true)]
"
	source += "    public static extern bool DeleteVolumeMountPoint(String directoryName);
"
	source += "}
"
	 
	csharpProvider = dotnetobject "Microsoft.CSharp.CSharpCodeProvider"
	compilerParams = dotnetobject "System.CodeDom.Compiler.CompilerParameters"

	compilerParams.ReferencedAssemblies.Add "System.dll"

	compilerParams.GenerateInMemory = true
	compilerResults = csharpProvider.CompileAssemblyFromSource compilerParams #(source)
			
	DriveAssembly = compilerResults.CompiledAssembly
)
 
 -------------------------------------------------------------------------
CreateDriveAssembly()
(
	DriveOps = DriveAssembly.CreateInstance "DriveOps"
	DriveOps.DeleteVolumeMountPoint "G:\\"
)

i’ve just fixed c# syntax and couple bugs

it’s not a good habit to rename library function if don’t change its sense, input or output parameters

ow, thank you. It’s working :))))
