[PATCH v2] winmm: Instanciate DirectInput8 class using CoCreateInstance.
Instead of linking with dinput8.dll and creating the class at load time, which causes some native hooks to fail loading. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=52222 Signed-off-by: Rémi Bernon <rbernon(a)codeweavers.com> --- v2: Reset dinput to NULL in case of creation failure, so that we don't release it or call CoUninitialize twice. dlls/winmm/Makefile.in | 2 +- dlls/winmm/joystick.c | 30 ++++++++++++++++++++++++++---- dlls/winmm/winemm.h | 1 - dlls/winmm/winmm.c | 2 -- 4 files changed, 27 insertions(+), 8 deletions(-) diff --git a/dlls/winmm/Makefile.in b/dlls/winmm/Makefile.in index 5439ae21678..3036526c14e 100644 --- a/dlls/winmm/Makefile.in +++ b/dlls/winmm/Makefile.in @@ -1,7 +1,7 @@ EXTRADEFS = -D_WINMM_ MODULE = winmm.dll IMPORTLIB = winmm -IMPORTS = uuid user32 advapi32 ole32 msacm32 dinput8 +IMPORTS = uuid user32 advapi32 ole32 msacm32 C_SRCS = \ driver.c \ diff --git a/dlls/winmm/joystick.c b/dlls/winmm/joystick.c index 5f5683e3e35..d055b3c9deb 100644 --- a/dlls/winmm/joystick.c +++ b/dlls/winmm/joystick.c @@ -152,11 +152,28 @@ static BOOL CALLBACK enum_instances( const DIDEVICEINSTANCEW *instance, void *co return DIENUM_CONTINUE; } -void joystick_load( HINSTANCE instance ) +static BOOL WINAPI joystick_load( INIT_ONCE *once, void *param, void **context ) { - HRESULT hr = DirectInput8Create( instance, DIRECTINPUT_VERSION, &IID_IDirectInput8W, - (void **)&dinput, NULL ); - if (FAILED(hr)) WARN( "could not create dinput instance, hr %#x\n", hr ); + HRESULT hr; + + CoInitialize( NULL ); + + hr = CoCreateInstance( &CLSID_DirectInput8, NULL, CLSCTX_INPROC_SERVER, &IID_IDirectInput8W, + (void **)&dinput ); + if (FAILED(hr)) goto failed; + + hr = IDirectInput8_Initialize( dinput, hWinMM32Instance, DIRECTINPUT_VERSION ); + if (FAILED(hr)) goto failed; + + return TRUE; + +failed: + if (dinput) IDirectInput8_Release( dinput ); + dinput = NULL; + + WARN( "Could not create dinput instance, hr %#x\n", hr ); + CoUninitialize(); + return FALSE; } void joystick_unload() @@ -173,15 +190,20 @@ void joystick_unload() } IDirectInput8_Release( dinput ); + CoUninitialize(); } static void find_joysticks(void) { + static INIT_ONCE init_once = INIT_ONCE_STATIC_INIT; + IDirectInputDevice8W *device; HANDLE event; DWORD index; HRESULT hr; + InitOnceExecuteOnce( &init_once, joystick_load, NULL, NULL ); + if (!dinput) return; index = 0; diff --git a/dlls/winmm/winemm.h b/dlls/winmm/winemm.h index 3459c2a85ef..52cab64b1c5 100644 --- a/dlls/winmm/winemm.h +++ b/dlls/winmm/winemm.h @@ -153,7 +153,6 @@ MMRESULT WINMM_CheckCallback(DWORD_PTR dwCallback, DWORD fdwOpen, BOOL mixer) DE void WINMM_DeleteWaveform(void) DECLSPEC_HIDDEN; -void joystick_load( HMODULE instance ) DECLSPEC_HIDDEN; void joystick_unload( void ) DECLSPEC_HIDDEN; /* Global variables */ diff --git a/dlls/winmm/winmm.c b/dlls/winmm/winmm.c index aab8bfb51a9..aa2dd50c4c1 100644 --- a/dlls/winmm/winmm.c +++ b/dlls/winmm/winmm.c @@ -144,8 +144,6 @@ BOOL WINAPI DllMain(HINSTANCE hInstDLL, DWORD fdwReason, LPVOID fImpLoad) if (!WINMM_CreateIData(hInstDLL)) return FALSE; - - joystick_load( hInstDLL ); break; case DLL_PROCESS_DETACH: if(fImpLoad) -- 2.34.0

For example if application already initialized with multithreaded mode.

Yes, thanks, Paul said something like that too on the previous version. I'll resend with delayload instead. -- Rémi Bernon <rbernon(a)codeweavers.com>
