Is it possible to distinguish #WM_LBUTTONDBLCLK from #WM_LBUTTONDOWN in your hook?
My problem is that a left double click generates a sequence of four messages:
#WM_LBUTTONDOWN, #WM_LBUTTONUP, #WM_LBUTTONDBLCLK and #WM_LBUTTONUP
and something like this:
Code: Select all
Select wParam
Case #WM_LBUTTONDBLCLK
OutputDebugString_("Left double click detected!")
Case #WM_MBUTTONDBLCLK
OutputDebugString_("Middle double click detected!")
Case #WM_XBUTTONDBLCLK
; We need to find out if X1 or X2 button was used!
; https://docs.microsoft.com/en-us/windows/desktop/inputdev/wm-xbuttondblclk
OutputDebugString_("X double click detected!")
; Press and hold cases
Case #WM_LBUTTONDOWN
OutputDebugString_("Left DOWN click detected!")
EndSelect
Would always trigger a "normal" left down press as well. Sure, this isn't wrong per se but in this
case a real left button down (pressed and hold) should be handled differently from a double click...

Don't know if this suits your needs, but you could do something like this...
Code: Select all
Enumeration
#NLH_DLL_CONTROL = #WM_USER + 101
EndEnumeration
Procedure TimerProc(hwnd, uMsg, idEvent, dwTime)
KillTimer_(hwnd, idEvent)
OutputDebugString_("Left DOWN click detected!")
EndProcedure
ProcedureDLL NLH( nCode, wParam, *lParam.MOUSEHOOKSTRUCT )
If nCode < 0 : ProcedureReturn CallNextHookEx_( @NLH(), nCode, wParam, *lParam ) : EndIf
Select wParam
Case #WM_LBUTTONDOWN
SetTimer_(*lParam\hwnd, 1, GetDoubleClickTime_(), @TimerProc())
Case #WM_LBUTTONDBLCLK
KillTimer_(*lParam\hwnd, 1)
OutputDebugString_("Left double click detected!")
EndSelect
ProcedureReturn CallNextHookEx_( @NLH(), nCode, wParam, *lParam )
EndProcedure

I'm linking this here in case you have any crashes related to making a global hook DLL with PureBasic:
viewtopic.php?f=4&t=61027
I haven't tested this recently so I don't know if it's become more stable since my original report.

I've never experienced such crashes with my DLL
(nlh is running since 2011)
