如果要编程一些可以更改Windows中键盘/鼠标配置的东西，该从哪里开始？

Question

Configuration as in the options you see in the Keyboard/Mouse settings under Windows. I have some .NET programming experience.

Answer 1

If you only wanted it to affect your own process you could use the InputLanguage class to change keyboard layout, but if I understand correctly you want to change the system wide settings?

As Stuart says, you're not really supposed to do this from an app so I don't think there's any "supported" way of doing it. However, I think all these settings are stored in the registry so you could probably do it by changing those settings and rebooting the PC.

Here's some links that might be worth looking at for changing the Keyboard layout:

Keyboard layout code
How do I configure the default keyboard layout during login?

Both those links are quite old but I think that it's likely that the same settings are still used.

If you want to change other keyboard settings than the layout, or if you want to change mouse settings, you could try googling for the name of the setting + "registry key" or something similar to find where it's stored, or maybe ask on the Superuser site.

Win-API is your friend here. Google this API for more information, with this you can retrieve and set a lots of systems parameters about mouse and keyboad:

SystemParametersInfo
The SystemParametersInfo function queries or sets systemwide parameters. This function can also update the user profile while setting a parameter.

Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long

If you for example send the uAction SPI_GETKEYBOARDDELAY to the function you will retrieve the keyboard repeat-delay setting. The pvParam parameter must point to an integer variable that receives the setting.

Some other (there are more) intreresting constants are:
GET:
SPI_GETMOUSE, SPI_GETMOUSEHOVERHEIGHT, SPI_GETMOUSEHOVERTIME, SPI_GETMOUSEHOVERWIDTH, SPI_GETMOUSEKEYS, SPI_GETMOUSETRAILS, SPI_GETNONCLIENTMETRICS, SPI_GETSTICKYKEYS, SPI_GETTOGGLEKEYS, SPI_GETWHEELSCROLLLINES

SET:
SPI_SETDOUBLECLICKTIME, SPI_SETDOUBLECLKHEIGHT, SPI_SETDOUBLECLKWIDTH, SPI_SETKEYBOARDDELAY, SPI_SETKEYBOARDPREF, SPI_SETKEYBOARDSPEED, SPI_SETLANGTOGGLE, SPI_SETMOUSE, SPI_SETMOUSEBUTTONSWAP, SPI_SETMOUSEHOVERHEIGHT, SPI_SETMOUSEHOVERTIME, SPI_SETMOUSEHOVERWIDTH, SPI_SETMOUSEKEYS, SPI_SETMOUSETRAILS
