function New-InMemoryModule | |

.SYNOPSIS | |
Creates an in-memory assembly and module | |

.DESCRIPTION | |
When defining custom enums, structs, and unmanaged functions, it is | |
necessary to associate to an assembly module. This helper function | |
creates an in-memory module that can be passed to the 'enum', | |
'struct', and Add-Win32Type functions. | |
.PARAMETER ModuleName | |
Specifies the desired name for the in-memory assembly and module. If | |
ModuleName is not provided, it will default to a GUID. | |

function Add-Win32Type | |
{ | |
<# | |
.SYNOPSIS | |
Creates a .NET type for an unmanaged Win32 function. | |
Author: Matthew Graeber (@mattifestation) | |
License: BSD 3-Clause | |
Required Dependencies: None | |
Optional Dependencies: func | |
.DESCRIPTION | |
Add-Win32Type enables you to easily interact with unmanaged (i.e. | |
Win32 unmanaged) functions in PowerShell. After providing | |
Add-Win32Type with a function signature, a .NET type is created | |
using reflection (i.e. csc.exe is never called like with Add-Type). | |
The 'func' helper function can be used to reduce typing when defining | |
multiple function definitions. | |
.PARAMETER DllName | |
The name of the DLL. | |
.PARAMETER FunctionName | |
The name of the target function. | |
.PARAMETER EntryPoint | |
The DLL export function name. This argument should be specified if the | |
specified function name is different than the name of the exported | |
function. | |
.PARAMETER ReturnType | |
The return type of the function. | |
.PARAMETER ParameterTypes | |
The function parameters. | |
.PARAMETER NativeCallingConvention | |
Specifies the native calling convention of the function. Defaults to | |
stdcall. | |
.PARAMETER Charset | |
If you need to explicitly call an 'A' or 'W' Win32 function, you can | |
specify the character set. | |
.PARAMETER SetLastError | |
Indicates whether the callee calls the SetLastError Win32 API | |
function before returning from the attributed method. | |
.PARAMETER Module | |
The in-memory module that will host the functions. Use | |
New-InMemoryModule to define an in-memory module. | |
.PARAMETER Namespace | |
An optional namespace to prepend to the type. Add-Win32Type defaults | |
to a namespace consisting only of the name of the DLL. | |
.EXAMPLE | |
$Mod = New-InMemoryModule -ModuleName Win32 | |
$FunctionDefinitions = @( | |
(func kernel32 GetProcAddress ([IntPtr]) @([IntPtr], [String]) -Charset Ansi -SetLastError), | |
(func kernel32 GetModuleHandle ([Intptr]) @([String]) -SetLastError), | |
(func ntdll RtlGetCurrentPeb ([IntPtr]) @()) | |
) | |
$Types = $FunctionDefinitions | Add-Win32Type -Module $Mod -Namespace 'Win32' | |
$Kernel32 = $Types['kernel32'] | |
$Ntdll = $Types['ntdll'] | |
$Ntdll::RtlGetCurrentPeb() | |
$ntdllbase = $Kernel32::GetModuleHandle('ntdll') | |
$Kernel32::GetProcAddress($ntdllbase, 'RtlGetCurrentPeb') | |
.NOTES | |
Inspired by Lee Holmes' Invoke-WindowsApi http://poshcode.org/2189 | |
When defining multiple function prototypes, it is ideal to provide | |
Add-Win32Type with an array of function signatures. That way, they | |
are all incorporated into the same in-memory module. | |

.SYNOPSIS | |
Creates an in-memory struct for use in your PowerShell session. | |
Author: Matthew Graeber (@mattifestation) | |
License: BSD 3-Clause | |
Required Dependencies: None | |
Optional Dependencies: field | |
.DESCRIPTION | |
The 'struct' function facilitates the creation of structs entirely in | |
memory using as close to a "C style" as PowerShell will allow. Struct | |
fields are specified using a hashtable where each field of the struct | |
is comprosed of the order in which it should be defined, its .NET | |
type, and optionally, its offset and special marshaling attributes. | |
One of the features of 'struct' is that after your struct is defined, | |
it will come with a built-in GetSize method as well as an explicit | |
converter so that you can easily cast an IntPtr to the struct without | |
relying upon calling SizeOf and/or PtrToStructure in the Marshal | |
class. | |
.PARAMETER Module | |
The in-memory module that will host the struct. Use | |
New-InMemoryModule to define an in-memory module. | |
.PARAMETER FullName | |
The fully-qualified name of the struct. | |
.PARAMETER StructFields | |
A hashtable of fields. Use the 'field' helper function to ease | |
defining each field. | |
.PARAMETER PackingSize | |
Specifies the memory alignment of fields. | |
.PARAMETER ExplicitLayout | |
Indicates that an explicit offset for each field will be specified. | |
.EXAMPLE | |
$Mod = New-InMemoryModule -ModuleName Win32 | |
$ImageDosSignature = psenum $Mod PE.IMAGE_DOS_SIGNATURE UInt16 @{ | |
DOS_SIGNATURE = 0x5A4D | |
OS2_SIGNATURE = 0x454E | |
OS2_SIGNATURE_LE = 0x454C | |
VXD_SIGNATURE = 0x454C | |
} | |
$ImageDosHeader = struct $Mod PE.IMAGE_DOS_HEADER @{ | |
e_magic = field 0 $ImageDosSignature | |
e_cblp = field 1 UInt16 | |
e_cp = field 2 UInt16 | |
e_crlc = field 3 UInt16 | |
e_cparhdr = field 4 UInt16 | |
e_minalloc = field 5 UInt16 | |
e_maxalloc = field 6 UInt16 | |
e_ss = field 7 UInt16 | |
e_sp = field 8 UInt16 | |
e_csum = field 9 UInt16 | |
e_ip = field 10 UInt16 | |
e_cs = field 11 UInt16 | |
e_lfarlc = field 12 UInt16 | |
e_ovno = field 13 UInt16 | |
e_res = field 14 UInt16[] -MarshalAs @('ByValArray', 4) | |
e_oemid = field 15 UInt16 | |
e_oeminfo = field 16 UInt16 | |
e_res2 = field 17 UInt16[] -MarshalAs @('ByValArray', 10) | |
e_lfanew = field 18 Int32 | |
} | |
# Example of using an explicit layout in order to create a union. | |
$TestUnion = struct $Mod TestUnion @{ | |
field1 = field 0 UInt32 0 | |
field2 = field 1 IntPtr 0 | |
} -ExplicitLayout | |
