So, I decided to give it a go. This is the cpython code:
info = GetSecurityInfo(GetCurrentProcess(),6,0)
SetSecurityInfo(process, 6, win32.win32security.DACL_SECURITY_INFORMATION |
win32.win32security.UNPROTECTED_DACL_SECURITY_INFORMATION,
None, None, info.GetSecurityDescriptorDacl(), info.GetSecurityDescriptorGroup())
When I run in IronPython, the following happens:
GetSecurityInfo returns an integer. This means I cannot do
info.GetSecurityDescriptorDacl() etc
If I leave out the last two (optional) parameters to SetSecurityInfo, I get a
return code of 998. Looking this up in winerror.h gives
ERROR_NOACCESS. This is not a rights problem afaik, since I am
running ipy with Admin rights.
Ok, so at this point, I thought "screw it, I'll do it in C#".
So, my C# code is simple for testing:
using System;
namespace UnmanagedCode
{
public class processSecurity
{
public int getValue(int value)
{ return value + 1; }
}
}
I compile it in VS2010 Express as a .NET Framework 4.0. I end up with
a DLL file. I then copy that DLL into a clean directory, and launch
ipy.exe in that directory.
IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4952
Type "help", "copyright", "credits" or "license" for more information.
>>> import clr
>>> clr.AddReferenceToFile("UnmanagedCode.dll")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IOError: System.IO.IOException: Could not add reference to assembly
UnmanagedCode.dll
So, I imported sys, and checked the path... the current directory is
in the path. At this point, I cannot figure out wtf is wrong. I have
looked and read and googled etc but the examples all seem to be
outdated and 'just work'... but not when I attempt them!
Some pointers as to how to get this working would be nice !
-Bye
