# WinSyncScroll
Scroll two windows simultaneously

## Demo

## How it works

The program uses the `SetWindowsHookEx` function to install a hook procedure that monitors low-level mouse events. When the user scrolls the source window, the program uses `SendInput` to simulate the same scroll event on the target window.

## Configuration

The program reads the configuration from the `appsettings.json` file. The configuration file must be in the same directory as the executable file.

### Legacy mode

When `"IsLegacyModeEnabled": true`, the program uses `SendMessage` (instead of `SendInput`) to send the `WM_MOUSEWHEEL` (or `WM_MOUSEHWHEEL`) message to the target window.

### Strict process id check

When `"IsStrictProcessIdCheckEnabled": true`, the program uses `WindowFromPoint` + `GetWindowThreadProcessId` to prevent scrolling the target window if the target or source window is currently not in the foreground.
