Tutorial Mw3 C# Base Trainer
#1
Well after releasing the D3D menu trainer in C++ i decided to make something more simple for the people who are starting in making trainers and stuff...

In this tutorial i will cover the following aspects:

- How to Import Functions
- How to detect a Process
- How to Write Process Memory (Editing Memory)
- How to Use GetAsyncKeyState ( Hotkeys )

First Steps:

Includes you are going to need:

CSHARP Code
  1. using System;
  2. using System.Collections.Generic;
  3. using System.ComponentModel;
  4. using System.Data;
  5. using System.Drawing;
  6. using System.Linq;
  7. using System.Text;
  8. using System.Runtime.InteropServices;
  9. using System.Diagnostics;
  10. using System.Windows.Forms;


Dll Imports:

CSHARP Code
  1. [DllImport("user32.dll")]
  2. public static extern short GetAsyncKeyState(Keys vKey);
  3.  
  4. [DllImport("kernel32.dll", EntryPoint = "WriteProcessMemory")]
  5. private static extern bool WriteProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, byte[] lpBuffer, uint nSize, [Out] int lpNumberOfBytesWritten);
  6.  
  7.  
  8. [DllImport("kernel32.dll", EntryPoint = "ReadProcessMemory")]
  9. private static extern bool ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, [Out] byte[] lpBuffer, int dwSize, [Out] int lpNumberOfBytesRead);
  10.  
  11. [DllImport("kernel32.dll", EntryPoint = "OpenProcess")]
  12. private static extern IntPtr OpenProcess(uint dwDesiredAccess, bool bInheritHandle, int dwProcessId);


Variables:

CSHARP Code
  1. public int opt1 = 0;
  2. public int opt2 = 0;
  3. public int opt3 = 0;
  4.  
  5. private static int ProcessID = -1;
  6. private static IntPtr ProcessHandle = IntPtr.Zero;


First create a new project:

[Image: tutn.png]

We are going to need a form with some labels on it:

[Image: scaled.php?server=163&filename=tut1z.png&res=medium]

Then you are going to rename those labels to the functions of your trainer:

[Image: scaled.php?server=828&filename=tut2e.png&res=medium]

After this we are going to create a Groupbox and another label for detecting if the game process is running:

[Image: scaled.php?server=38&filename=tut3h.png&res=medium]

Now we are going to make the code for detecting the game process:

1 - Create a Timer;
2 - Double Click on the Timer and insert this code:

[Image: tut4q.png]

CSHARP Code
  1. System.Diagnostics.Process[] myprocesses = System.Diagnostics.Process.GetProcessesByName("iw5sp");
  2. if (myprocesses.Length != 0)
  3. {
  4. label5.Text = "Mw3 Found!";
  5. label5.ForeColor = Color.Lime;
  6.  
  7. }


Now we are going to make variables for our trainer options and import a function to detect our hotkeys:

CSHARP Code
  1. using System.Runtime.InteropServices;//Dont forget to add this to the includes...
  2.  
  3. ///////////////////////////// - Import / Variables - ///////////////////////////////
  4.  
  5. public int opt1 = 0;
  6. public int opt2 = 0;
  7. public int opt3 = 0;
  8.  
  9. [DllImport("user32.dll")]
  10. public static extern short GetAsyncKeyState(Keys vKey);


[Image: tut4v.png]

Now we are going to create another timer for writting memory and detecting our hotkeys:

[Image: tut5e.png]

[Image: scaled.php?server=807&filename=tut6.png&res=medium]

CSHARP Code
  1. private void timer2_Tick(object sender, EventArgs e)
  2. {
  3. bool OPT1 = Convert.ToBoolean(GetAsyncKeyState(Keys.F1));
  4. if (OPT1 == true)
  5. {
  6. if (opt1 == 0)
  7. {
  8. opt1 = 1;
  9. }
  10. else
  11. {
  12. opt1 = 0;
  13. }
  14. }
  15. bool OPT2 = Convert.ToBoolean(GetAsyncKeyState(Keys.F2));
  16. if (OPT2 == true)
  17. {
  18. if (opt2 == 0)
  19. {
  20. opt2 = 1;
  21. }
  22. else
  23. {
  24. opt2 = 0;
  25. }
  26. }
  27. bool OPT3 = Convert.ToBoolean(GetAsyncKeyState(Keys.F3));
  28. if (OPT3 == true)
  29. {
  30. if (opt3 == 0)
  31. {
  32. opt3 = 1;
  33. }
  34. else
  35. {
  36. opt3 = 0;
  37. }
  38. }
  39. bool OPT4 = Convert.ToBoolean(GetAsyncKeyState(Keys.F4));
  40. if (OPT4 == true)
  41. {
  42. int activated = 0;
  43. if (activated == 0)
  44. {
  45.  
  46. }
  47. else
  48. {
  49.  
  50. }
  51. }
  52. if (opt1 == 1)
  53. {
  54.  
  55. }
  56. if (opt2 == 1)
  57. {
  58.  
  59. }
  60. if (opt3 == 1)
  61. {
  62.  
  63. }
  64. }


Ok now we are ready for importing the functions for opening our game process and writting memory:

[Image: tut7k.png]

CSHARP Code
  1. private static int ProcessID = -1;
  2. private static IntPtr ProcessHandle = IntPtr.Zero;
  3.  
  4. [DllImport("kernel32.dll", EntryPoint = "WriteProcessMemory")]
  5. private static extern bool WriteProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, byte[] lpBuffer, uint nSize, [Out] int lpNumberOfBytesWritten);
  6.  
  7.  
  8. [DllImport("kernel32.dll", EntryPoint = "ReadProcessMemory")]
  9. private static extern bool ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, [Out] byte[] lpBuffer, int dwSize, [Out] int lpNumberOfBytesRead);
  10.  
  11. [DllImport("kernel32.dll", EntryPoint = "OpenProcess")]
  12. private static extern IntPtr OpenProcess(uint dwDesiredAccess, bool bInheritHandle, int dwProcessId);


And finally we are going to open the game process and writte it memory to get some results:

Open Game Process:

CSHARP Code
  1. private void timer1_Tick(object sender, EventArgs e)
  2. {
  3. System.Diagnostics.Process[] myprocesses = System.Diagnostics.Process.GetProcessesByName("iw5sp");
  4. if (myprocesses.Length != 0)
  5. {
  6. label5.Text = "Mw3 Found!";
  7. label5.ForeColor = Color.Lime;
  8. timer2.Start();
  9. Process[] processes = Process.GetProcessesByName("iw5sp"); // in the "iw5sp" is the name of the process
  10. ProcessID = processes[0].Id;
  11. ProcessHandle = OpenProcess(0x001F0FFF/*PROCESS_ALL_ACCESS*/, false, ProcessID);
  12. }
  13. }


NOP function:

http://www.itsmods.com/forum/Thread-Tuto...-in-C.html

CSHARP Code
  1. private void timer2_Tick(object sender, EventArgs e)
  2. {
  3. bool OPT1 = Convert.ToBoolean(GetAsyncKeyState(Keys.F1));
  4. if (OPT1 == true)
  5. {
  6. if (opt1 == 0)
  7. {
  8. opt1 = 1;
  9. label1.ForeColor = Color.Lime;
  10. }
  11. else
  12. {
  13. opt1 = 0;
  14. label1.ForeColor = Color.Red;
  15. }
  16. }
  17. bool OPT2 = Convert.ToBoolean(GetAsyncKeyState(Keys.F2));
  18. if (OPT2 == true)
  19. {
  20. if (opt2 == 0)
  21. {
  22. opt2 = 1;
  23. label2.ForeColor = Color.Lime;
  24. }
  25. else
  26. {
  27. opt2 = 0;
  28. label2.ForeColor = Color.Red;
  29. }
  30. }
  31. bool OPT3 = Convert.ToBoolean(GetAsyncKeyState(Keys.F3));
  32. if (OPT3 == true)
  33. {
  34. if (opt3 == 0)
  35. {
  36. opt3 = 1;
  37. label3.ForeColor = Color.Lime;
  38. }
  39. else
  40. {
  41. opt3 = 0;
  42. label3.ForeColor = Color.Red;
  43. }
  44. }
  45. bool OPT4 = Convert.ToBoolean(GetAsyncKeyState(Keys.F4));
  46. if (OPT4 == true)
  47. {
  48. int activated = 0;
  49. if (activated == 0)
  50. {
  51. byte[] nop = { 0x90, 0x90, 0x90, 0x90, 0x90 };// 5 bytes
  52. WriteProcessMemory(ProcessHandle, (IntPtr)0x004DBB96, nop, 5/*amount of bytes written(5)*/, 0);
  53. label4.ForeColor = Color.Lime;
  54. activated = 1;
  55. }
  56. else
  57. {
  58. byte[] nop = { 0xE8, 0xC5, 0x72, 0x03, 0x00 };// 5 bytes
  59. WriteProcessMemory(ProcessHandle, (IntPtr)0x004DBB96, nop, 5/*amount of bytes written(5)*/, 0);
  60. label4.ForeColor = Color.Red;
  61. activated = 0;
  62. }
  63. }
  64. if (opt1 == 1)
  65. {
  66. int val = 999;
  67. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7AA0, BitConverter.GetBytes(val), 4, 0);
  68. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7B18, BitConverter.GetBytes(val), 4, 0);
  69. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7AA8, BitConverter.GetBytes(val), 4, 0);
  70. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7B24, BitConverter.GetBytes(val), 4, 0);
  71. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7B30, BitConverter.GetBytes(val), 4, 0);
  72. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7B48, BitConverter.GetBytes(val), 4, 0);
  73. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7B54, BitConverter.GetBytes(val), 4, 0);
  74. WriteProcessMemory(ProcessHandle, (IntPtr)0x012A7B3C, BitConverter.GetBytes(val), 4, 0);
  75. }
  76. if (opt2 == 1)
  77. {
  78. int val = 999;
  79. WriteProcessMemory(ProcessHandle, (IntPtr)0x010BD628, BitConverter.GetBytes(val), 4, 0);
  80. }
  81. if (opt3 == 1)
  82. {
  83. int val = 0;
  84. WriteProcessMemory(ProcessHandle, (IntPtr)0x12A7948, BitConverter.GetBytes(val), 4, 0);
  85. WriteProcessMemory(ProcessHandle, (IntPtr)0x8ABA88, BitConverter.GetBytes(val), 4, 0);
  86. }
  87. }


And the final code should be:

Well i know is not that detailed but i think its a good tutorial to start with.

You can do your modifications to design and make it a little less ugly.

Thats all,

Thanks Barata...

Next time i will make a C++ form trainer tuto, is almost the same as this but no problem!
