[MFC] Capture mouse?

[Skute]

Hi,

i want to create a simple mouse macro (as a basic intro to learning MFC). I can get the mouse to be captured when holding down a mouse button, but i cant get it to be captured *all* the time.

I know the requirement is to only capture when the mouse button is held down, but is there any way to override this? ie, anyway to "pretend" that the mouse button is held down?

this is a copy/paste from MSDN:
Mouse capture is also affected by the Windows 95/98 and Windows NT/Windows 2000 localized input queues. If the mouse is captured on mouse down, the window capturing the mouse receives mouse input until the mouse button is released, as in Windows 3.x. But if the mouse is captured while the mouse button is up, the window receives mouse input only as long as the mouse is over that window or another window created by the same thread.

yeah i know, ive been trying to "fool" windows into thinking the mouse is being held down by having a seperate thread make calls to SendMessage(WM_LBUTTONDOWN, , ).

you can try to set a hook, see SetWindowsHook/SetWindowsHookEx

Cool thanks,

following on, i think i have 3 options:

a) SetWindowHookEx with WH_GETMESSAGE to watch for WM_MOUSEMOVE messages
b) SetWindowHookEx with LowLevelMouseProc
c) Use mouse_event to constantly send left mouse button down messages


What would you recommend?

I recommend you the first one(a). But is up to you.
