Inspecting the Right Alt
key messages using Microsoft Spy++
returns the following:
WM_KEYDOWN nVirtKey:VK_CONTROL
WM_KEYDOWN nVirtKey:VK_MENU
WM_SYSKEYUP nVirtKey:VK_CONTROL
WM_KEYUP nVirtKey:VK_MENU
Why does the key generate 2 messages VK_CONTROL
and VK_MENU
? Why is the type of VK_CONTROL
SYS (system) while VK_MENU
non-system?
