DirectInput8Create失败：E_INVALIDARG
我正在使用DirectInput与Direct3D 11，并编译为x64，我从这一行得到一个E_INVALIDARG：
HRESULT hr = DirectInput8Create(hInstance, DIRECTINPUT_VERSION, IID_IDirectInput8, reinterpret_cast<void **>(&this->_d8Input), 0);
没有找到相关结果

在_tWinMain函数中我添加了：void *outPtr = NULL; HRESULT aResult = DirectInput8Create(hInstance, DIRECTINPUT_VERSION, IID_IDirectInput8, &outPtr, NULL); if (aResult != DI_OK) { LPCWSTR emesg = L"??"; switch (aResult) { case DIERR_BETADIRECTINPUTVERSION: emesg = L"Beta Directinput version"; break; case DIERR_INVALIDPARAM: emesg = L"Invalid Parameter"; break; case DIERR_OLDDIRECTINPUTVERSION: emesg = L"Old Directinput Version"; break; case DIERR_OUTOFMEMORY: emesg = L"Out of Memory"; break; } MessageBox(GetDesktopWindow(), emesg, emesg, 0); }
