Allow scrolling with a trackball without scroll wheel by using a low level mouse hook.

Changes the behaviour of one or both X-Buttons (typically buttons 3, 4) to

• Scrolling, i.e. vertical/horizontal mouse wheel events, when an X-Button is pressed and the trackball is moved vertically/horizontally
• Middle button click, when an X-Button is pressed and released without trackball movement

• A trackball or mouse with X-Buttons
• A Microsoft Windows x64 operating system with .NET 4.5.2

This software has been tested with a Logitech Marble Trackball(tm) and Microsoft Windows 10.

• Execute TrackballScroll.exe, no installation is necessary.
• Configuration options are available using right click on the icon in the systray (the icons next to the clock).
• When using this program with a driver software that allows customization of the button behavior, make sure to set the X-Buttons to default behavior. E.g. with a Logitech Trackman Marble, make sure to set the buttons 3 and 4 to default button behaviour and not back/Universal Scroll.
• The lines scrolled per wheel event are determined by the Microsoft Windows mouse wheel settings.

• Clone the repository from the github page or download the latest source code archive
• Open the solution with Microsoft Visual Studio 2017.
• Change the build type to Release.
• Build the solution

• v6 fixes #20: allows to reverse scrolling directions
• v5 fixes #17 + improved stability (rewrite of the mouse hook, state machine and mouse event sending)
• v4 prevents #16... sort of (middle clicks can be disabled if necessary using the tray menu).
• v3 feature #12: Allows to choose which X-buttons are used and saves the settings. Also changed versioning scheme to single numbers.
• v2.1.2 fixes #14. Compatibility with Windows 10 versions of 2017.
• v2.1.1 fixes issues #8, #9, #10. Instead of calculating the scaled coordinates, both original and scaled coordinates are memorized.
• v2.1.0 fixes issue #5 with high dpi scaling. Note: The app must be restartet after changing the scaling factor in windows.
• v2.0.1 Added an application icon and moved all strings to a resource file.
• v2.0.0 The application is accessible through a systray-icon, the console window is gone. Converted from C++ to C#.
• v1.1.0 Add horizontal scroll
• v1.0.1 Add info to the console window
