Feel free to use code inside or forks and add new functionality to meet your needs. 6 | 7 | ## Motivation 8 | 9 | I created this library to help me read-write memory from any process, and game (at that time it's Warcraft III). 10 | I copied the code and started the new project over and over again. 11 | So I decided to learn how to create a library and plug it into my game helper. 12 | 13 | ## Functions 14 | 15 | ** Sometimes you might need to run an executable as administrator to access other process's memory. 16 | 17 | OpenProcess using process name, this will select the first process name that we've found. 18 | 19 | ```cs 20 | MemoryX.Memory MemX = new MemoryX.Memory(); 21 | MemX.GetProcessHandle("notepad"); 22 | ``` 23 | 24 | OpenProcess using PID. 25 | 26 | ```cs 27 | MemoryX.Memory MemX = new MemoryX.Memory(); 28 | MemX.GetProcessHandle(12345); 29 | ``` 30 | 31 | 32 | ### Get BadAddress of a module 33 | 34 | ```cs 35 | public long GetBaseAddress(String moduleName) 36 | ``` 37 | 38 | ![baseAddress](https://github.com/blackSourcez/MemoryX/raw/master/images/baseAddress.png) 39 | 40 | 41 | #### Example 42 | ```cs 43 | var procName = "Tutorial-x86_64"; 44 | long baseAddress = myProc.GetBaseAddress(procName + ".exe"); 45 | Console.WriteLine("BaseAddress: {0}", (baseAddress).ToString("X")); // BaseAddress: 100000000 46 | ``` 47 | 48 | ## Write Process Memory 49 | 50 | ```cs 51 | WriteMemory( [address], [data types]) 52 | ``` 53 | 54 | #### Write integer into selected address 55 | 56 | ```cs 57 | WriteMemory( address, 12345); 58 | ``` 59 | 60 | #### Write string into selected address 61 | 62 | ```cs 63 | WriteMemory( address, "Hello"); 64 | ``` 65 | 66 | #### Write float value into selected address 67 | 68 | ```cs 69 | WriteMemory(address, 3.1415928f); 70 | ``` 71 | 72 | #### Write double value into selected address 73 | 74 | ```cs 75 | WriteMemory(address, 7.1474d); 76 | ``` 77 | 78 | #### Write a single byte value into address 79 | 80 | ```cs 81 | WriteMemory(address, 0xba); 82 | ``` 83 | 84 | #### Write an array of bytes into address 85 | 86 | ```cs 87 | WriteMemory(address, new byte[] { 0xaa, 0xbb, 0xcc }); 88 | ``` 89 | 90 | --------- 91 | 92 | 93 | ## Read Process Memory 94 | 95 | 96 | #### Read one byte 97 | 98 | ```cs 99 | Console.WriteLine("BYTES IS " + myProc.ReadMemory(address , 1)[0].ToString("X")); 100 | ``` 101 | 102 | #### Read int16 from memory using BitConverter 103 | 104 | ```cs 105 | byte[] b = myProc.ReadMemory(address, 2); 106 | Console.WriteLine(BitConverter.ToInt16(b, 0)); 107 | ``` 108 | 109 | --- 110 | 111 | ## For others example use: 112 | 113 | ```csharp 114 | // New an object , one object per process 115 | MemoryX.Memory myProc = new MemoryX.Memory();

162 | 163 | 164 | // get a base address of module and print out 165 | Console.WriteLine(myProc.GetBaseAddress("notepad.exe").ToString("X")); 166 | ``` 167 | 168 | ## Read memory pointer 169 | ```cs 170 | MemoryX.Memory myProc = new MemoryX.Memory();
