Fix API documentation and examples; add comprehensive documentation suite
- Example5: Fix format string bugs (alignment specifier placement, SafeMemoryHandle formatting) - Example4: Fix DetourManager.Detour() → Create() in all doc strings - Example3: Fix MemoryBase.CreateFunction() → InProcessInvoker.CreateFunction() in doc strings - Examples 1-5: Correct all runtime errors and API mismatches vs actual WhiteMagic API - README: Fix DetourManager.Detour() examples to use Create(); add missing code fence markers - Add WhiteMagic.Examples project with 5 comprehensive example files (40+ sub-examples) - Add docfx.json and toc.md for DocFX API reference generation - Add 5 conceptual guides: architecture, memory-access, execution-models, hooking, troubleshooting - Ensure zero errors, zero warnings across all projects (net8.0-windows) Doc strings now teach correct APIs; runtime format bugs eliminated; build succeeds.

# WhiteMagic Examples
|
||||
|
||||
This directory contains comprehensive examples demonstrating all major features of the WhiteMagic library.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- **Target Process**: Most examples use Notepad as the target. Launch Notepad before running the examples.
|
||||
- **Administrator Privileges**: Some operations require elevated privileges. Run Visual Studio or terminal as Administrator.
|
||||
- **.NET 8.0 SDK**: Ensure you have .NET 8.0 installed.
|
||||
|
||||
## Running the Examples
|
||||
|
||||
### From Visual Studio
|
||||
|
||||
1. Open `WhiteMagic.slnx` in Visual Studio
|
||||
2. Set `WhiteMagic.Examples` as the startup project
|
||||
3. Press F5 to run
|
||||
|
||||
### From Command Line
|
||||
|
||||
```bash
|
||||
# Navigate to the examples directory
|
||||
cd WhiteMagic.Examples
|
||||
|
||||
# Run the examples
|
||||
dotnet run
|
||||
```
|
||||
|
||||
## Example Categories
|
||||
|
||||
### 1. Basic Memory Operations (`Example1_BasicMemoryOperations.cs`)
|
||||
|
||||
**Demonstrates:**
|
||||
- Reading and writing primitive types (int, float, double, bool)
|
||||
- Reading and writing arrays
|
||||
- Reading and writing strings (ANSI and Unicode)
|
||||
- Reading and writing raw bytes
|
||||
- Using `RemotePointer` for fluent pointer arithmetic
|
||||
- Relative addressing (module-relative offsets)
|
||||
- Error handling for memory operations
|
||||
- Working with custom structs
|
||||
|
||||
**Key Takeaways:**
|
||||
- All memory operations go through the `Magic.Memory` API
|
||||
- Use `RemotePointer` for clean, fluent pointer arithmetic
|
||||
- Reads throw exceptions on failure; writes return `false`
|
||||
- Prefer blittable types for best performance
|
||||
|
||||
### 2. Pattern Scanning (`Example2_PatternScanning.cs`)
|
||||
|
||||
**Demonstrates:**
|
||||
- Simple pattern scans with wildcards
|
||||
- Multiple pattern scans in one operation
|
||||
- Region-specific scanning (e.g., .text section only)
|
||||
- Finding function signatures
|
||||
- Cached pattern scanning for performance
|
||||
- Flexible wildcard patterns
|
||||
- Signature-based scanning (code caves, NOPs, INT3s)
|
||||
- Pattern validation
|
||||
|
||||
**Key Takeaways:**
|
||||
- Use IDA-style patterns: `"48 8B ? ? ? ? ?"` where `?` is a wildcard
|
||||
- Cache results for repeated scans
|
||||
- Narrow search region when possible for better performance
|
||||
|
||||
### 3. Execution Models (`Example3_ExecutionModels.cs`)
|
||||
|
||||
**Demonstrates:**
|
||||
- **RemoteThreadExecutor**: `CreateRemoteThread` for thread-agnostic calls
|
||||
- **MainThreadPump**: Crash-safe execution for state-sensitive calls
|
||||
- **InProcessInvoker**: Direct delegates for in-process calls
|
||||
- Choosing the right execution model
|
||||
- Combining execution models (inject then switch)
|
||||
- Error handling for each model
|
||||
|
||||
**Key Takeaways:**
|
||||
- **CRITICAL**: Use the right model for the payload:
|
||||
- `RemoteThreadExecutor`: Only for thread-agnostic functions (WinAPI, DLL injection)
|
||||
- `MainThreadPump`: For state-sensitive calls (game state, scripting, UI)
|
||||
- `InProcessInvoker`: Only after DLL injection
|
||||
- Using the wrong model crashes the target application
|
||||
|
||||
### 4. Function Hooking (`Example4_FunctionHooking.cs`)
|
||||
|
||||
**Demonstrates:**
|
||||
- **Inline Detours**: Function hooking with trampolines
|
||||
- Detours with parameter modification
|
||||
- Detours with return value modification
|
||||
- Multiple detours (chain hooking)
|
||||
- **Byte Patching**: Named byte patches
|
||||
- NOP patching (removing instructions)
|
||||
- Conditional patching (toggle on/off)
|
||||
- Prologue validation and safety
|
||||
- Automatic restoration on disposal
|
||||
|
||||
**Key Takeaways:**
|
||||
- Detours ONLY work in-process (requires DLL injection)
|
||||
- Patches work externally (no injection required)
|
||||
- `DetourManager`/`PatchManager` are NOT thread-safe
|
||||
- All hooks and patches auto-restore on disposal
|
||||
|
||||
### 5. High-Level API (`Example5_HighLevelAPI.cs`)
|
||||
|
||||
**Demonstrates:**
|
||||
- **RemotePointer**: Fluent pointer arithmetic with `[]` indexing
|
||||
- **RemoteModule**: Module enumeration and export resolution
|
||||
- **RemoteFunction**: Function resolution and execution
|
||||
- **ManagedPeb**/**ManagedTeb**: Typed PEB/TEB access
|
||||
- **RemoteWindow**: Window manipulation (move, resize, flash, activate)
|
||||
- Memory allocation and freeing
|
||||
- Module pattern scanning
|
||||
- Export function iteration
|
||||
- Chaining high-level operations
|
||||
|
||||
**Key Takeaways:**
|
||||
- Use high-level APIs for cleaner, more readable code
|
||||
- `magic["ModuleName"]` returns a `RemoteModule`
|
||||
- `module["FunctionName"]` returns a `RemoteFunction`
|
||||
- All high-level operations are built on top of the core memory API
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Reading a Nested Structure
|
||||
|
||||
```csharp
|
||||
// GameManager -> PlayerList -> Player[i] -> Health
|
||||
IntPtr gameManagerPtr = magic.Memory.ImageBase + 0x1000;
|
||||
IntPtr playerListPtr = magic.Memory.Read<IntPtr>(gameManagerPtr + 0x20);
|
||||
IntPtr playerPtr = magic.Memory.Read<IntPtr>(playerListPtr + (playerIndex * 8));
|
||||
int health = magic.Memory.Read<int>(playerPtr + 0x4);
|
||||
```
|
||||
|
||||
### Using RemotePointer for Cleaner Code
|
||||
|
||||
```csharp
|
||||
int health = magic[gameManagerPtr]
|
||||
.Read<IntPtr>(0x20) // PlayerList
|
||||
.Let(ptr => magic[ptr]
|
||||
.Read<IntPtr>(playerIndex * 8)) // Player
|
||||
.Let(ptr => magic[ptr]
|
||||
.Read<int>(0x4)); // Health
|
||||
```
|
||||
|
||||
### Safe Retry Loop for Writes
|
||||
|
||||
```csharp
|
||||
for (int i = 0; i < 5; i++)
|
||||
{
|
||||
if (magic.Memory.Write(address, value))
|
||||
break;
|
||||
Thread.Sleep(100 * (1 << i)); // Exponential backoff
|
||||
}
|
||||
```
|
||||
|
||||
### Crash-Safe State Access
|
||||
|
||||
```csharp
|
||||
// WRONG (crashes in most games)
|
||||
int health = magic.RemoteThread.Execute<int>(fn, CallConvention.Cdecl);
|
||||
|
||||
// RIGHT (crash-safe)
|
||||
var pump = magic.CreateMainThreadPump(frameAddress);
|
||||
int health = await pump.Enqueue(() => magic.Memory.Read<int>(healthAddress));
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Process is not open for read/write"
|
||||
|
||||
**Cause**: Process has exited or handle is invalid
|
||||
|
||||
**Solution**: Ensure process is still running and handle is valid
|
||||
|
||||
### "Read returns default value"
|
||||
|
||||
**Cause**: Address is invalid or memory is protected
|
||||
|
||||
**Solution**: Verify address with debugger; check memory protection
|
||||
|
||||
### "Write returns false"
|
||||
|
||||
**Cause**: Memory is read-only or process has exited
|
||||
|
||||
**Solution**: Retry with delay; use `PatchManager` for code patches
|
||||
|
||||
### "CreateRemoteThread failed"
|
||||
|
||||
**Cause**: Insufficient permissions or target is protected
|
||||
|
||||
**Solution**: Run as Administrator; check target process protection
|
||||
|
||||
### "Crash when calling target function"
|
||||
|
||||
**Cause**: Calling single-threaded function from remote thread
|
||||
|
||||
**Solution**: Use `MainThreadPump` instead of `RemoteThreadExecutor`
|
||||
|
||||
### "Detour failed: prologue too short"
|
||||
|
||||
**Cause**: Function prologue is shorter than minimum (5 bytes)
|
||||
|
||||
**Solution**: Hook different function; patch deeper into function
|
||||

||||

||||
## Safety Reminders
|
||||
|
||||
⚠️ **CRITICAL WARNINGS**:
|
||||
|
||||
1. **Execution Model Choice**:
|
||||
- `RemoteThreadExecutor`: ONLY for thread-agnostic functions
|
||||
- `MainThreadPump`: For state-sensitive calls (crash-safe)
|
||||
- `InProcessInvoker`: Only after DLL injection
|
||||
- **Using the wrong model crashes the target application!**
|
||||
|
||||
2. **Detours vs Patches**:
|
||||
- Detours ONLY work in-process (requires injection)
|
||||
- Patches work externally (no injection required)
|
||||
|
||||
3. **Thread Safety**:
|
||||
- `DetourManager`/`PatchManager` are NOT thread-safe
|
||||
- Synchronize concurrent modifications
|
||||
|
||||
4. **Handle Management**:
|
||||
- Always use `using` statements or dispose `Magic` properly
|
||||
- Leaked handles can cause resource exhaustion
|
||||
|
||||
5. **Anti-Cheat Detection**:
|
||||
- Some operations (e.g., `CreateRemoteThread`) are easily detected
|
||||
- Use `MainThreadPump` for stealthier operation
