The input locale identifier specifies a locale as well as the physical layout of the keyboard. BlockInput Blocks keyboard and mouse input events from reaching applications. EnableWindow Enables or disables mouse and keyboard input to the specified window or control. GetActiveWindow The GetActiveWindow function retrieves the window handle to the active window attached to the calling thread"s message queue. GetAsyncKeyState The GetAsyncKeyState function determines whether a key is up or down at the time the function is called, and whether the key was pressed after a previous call to GetAsyncKeyState. GetFocus Retrieves the handle to the window that has the keyboard focus, if the window is attached to the calling thread"s message queue. GetKBCodePage Returns the current code page. GetKeyboardLayout The GetKeyboardLayout function retrieves the active input locale identifier (formerly called the keyboard layout) for the specified thread. If the idThread parameter is zero, the input locale identifier for the active thread is returned. GetKeyboardLayoutList The GetKeyboardLayoutList function retrieves the input locale identifiers (formerly called keyboard layout handles) corresponding to the current set of input locales in the system. GetKeyboardLayoutName The GetKeyboardLayoutName function retrieves the name of the active input locale identifier (formerly called the keyboard layout). GetKeyboardState The GetKeyboardState function copies the status of the 256 virtual keys to the specified buffer. GetKeyNameText The GetKeyNameText function retrieves a string that represents the name of a key. GetKeyState The GetKeyState function retrieves the status of the specified virtual key. The status specifies whether the key is up, down, or toggled (on, off—alternating each time the key is pressed). IsWindowEnabled The IsWindowEnabled function determines whether the specified window is enabled for mouse and keyboard input. keybd_event Synthesizes a keystroke. MapVirtualKey Translates (maps) a virtual-key code into a scan code or character value, or translates a scan code into a virtual-key code. RegisterHotKey The RegisterHotKey function defines a system-wide hot key. SetFocus Sets the keyboard focus to the specified window. The window must be attached to the calling thread"s message queue SetKeyboardState The SetKeyboardState function copies a 256-byte array of keyboard key states into the calling thread"s keyboard input-state table. ToAscii Translates the specified virtual-key code and keyboard state to the corresponding character or characters. UnregisterHotKey The UnregisterHotKey function frees a hot key previously registered by the calling thread. VkKeyScan Translates a character to the corresponding virtual-key code and shift state for the current keyboard.
