Personal opinion:
Whether to accept the message window is a false proposition,
On receiving any message window, the difference only, after then receive discarded after processing, processing to the default process again after processing,...

It is the two state
WM_NCACTIVATE SendMessage (HWND, True, 0)
SendMessage (HWND WM_NCACTIVATE, False, 0)

CodePudding user response:

Is compared with the GetActiveWindow judgments,
If a window is active window has nothing to do with whether its response to the two messages,

I don't want to judge whether the window response or activity of what I asked questions I feel already very clear ah, why can't save me

CodePudding user response:

It can see if there are a great god to solve

CodePudding user response:

You send a (phone) short message to others, others see didn't see you don't know,
WM_NCACTIVATE is also same,
I really don't know what are you thinking about?

CodePudding user response:

refer to 6th floor Tiger_Zhao response:

you send a (phone) short message to others, others didn't look at you don't know,
WM_NCACTIVATE is also same,
I really don't know what are you thinking about?

Just said Windows 7 system I don't know what else to accept SendMessage (HWND WM_NCACTIVATE, True, 0) message window closes the window will get red fork fork
I think it will be your technology is not enough, not really can't judge, may be I am a novice, but you yourself think is the way it is, this so, asked many also tired, no one know I have to study the yourself,
