This is a command line utility to switch primary and secondary mouse buttons. I regularly switch sides with my mouse to try and avoid repetitive posture related issues while working in front of the box. This gave me a build window command line story for switching mouse buttons without having to navigate to the mouse properties gui.
It uses a registry lookup to determine what mouse buttons setting is currently in place then a managed code api wrapper call to the win32 SwapMouseButton api to switch the setting to the opposite of whatever it currently is.
reg query "hkcu\Control Panel\Mouse" /v SwapMouseButtons
- reg_sz = 0 = right handed mouse buttons setting is enabled
- reg_sz = 1 = left handed mouse buttons setting is enabled
reg add "hkcu\Control Panel\Mouse" /v SwapMouseButtons /t reg_sz /d 0|1
- this doesn't apply setting until you signout and back in again presumably because that triggers mouse button settings lookup and initialization
Calling SwapMouseButton win32 api changes what is currently in effect but does not change the registry setting. So that needs to be modified as well otherwise the next time you open and close mouse settings control panel, main.cpl, the setting will revert to what the registry setting is configured to be.
Testing showed that for user logged in who was member of administrators group only needed to open registry key with writable enabled and only needed user access control app.manifest run elevanted permissions, which generates yes/no popup, to address use of utility by user who is not member of administrators security group. So leaving that behavior out for usability purposes, i.e. so cli utility operates w/o any popups.
