Functions
| Acquire The IDirectInputJoyConfig8::Acquire method acquires "joystick configuration mode." Only one application can be in joystick configuration mode at a time; subsequent attempts by other applications to acquire this mode should receive the error DIERR_OTHERAPPHASPRIO. After entering configuration mode, the application can make alterations to the global joystick configuration settings. The application should check the existing settings before installing the new ones in case another application changed the settings in the interim. |
| AddNewHardware The IDirectInputJoyConfig8::AddNewHardware method displays the Add New Hardware dialog box which guides the user through installing a new input device. |
| AddRef The IDirectInputEffectDriver::AddRef method increases the reference count of the DirectInputEffectDriver object by 1. This method is part of the IUnknown interface inherited by DirectInputEffectDriver. |
| AddRef The IDirectInputJoyConfig8::AddRef method increases the reference count of the DirectInputJoyConfig object by 1. This method is part of the IUnknown interface inherited by DirectInputJoyConfig. |
| DeleteConfig The IDirectInputJoyConfig8::DeleteConfig method deletes configuration information about a joystick. |
| DeleteType The IDirectInputJoyConfig8::DeleteType method removes information about a joystick type. Use this method with caution; it is the caller's responsibility to ensure that no joystick refers to the deleted type. |
| DestroyEffect The IDirectInputEffectDriver::DestroyEffect method removes an effect from the device. If the effect is playing, the driver should stop it before unloading it. |
| DeviceID The IDirectInputEffectDriver::DeviceID method sends the driver the identity of the device. |
| DownloadEffect The IDirectInputEffectDriver::DownloadEffect method sends an effect to the device. |
| EnumTypes The IDirectInputJoyConfig8::EnumTypes method enumerates the joystick types currently supported by DirectInput. |
| Escape The IDirectInputEffectDriver::Escape method escapes to the driver. This method is called in response to an application invoking the IDirectInputEffect::Escape or IDirectInputDevice::Escape methods. |
| GetConfig The IDirectInputJoyConfig8::GetConfig method obtains information about a joystick's configuration. |
| GetEffectStatus The IDirectInputEffectDriver::GetEffectStatus method obtains information about the status of an effect. |
| GetForceFeedbackState The IDirectInputEffectDriver::GetForceFeedbackState method retrieves the force-feedback state for the device. |
| GetTypeInfo The IDirectInputJoyConfig8::GetTypeInfo method obtains information about a joystick type. |
| GetUserValues The IDirectInputJoyConfig8::GetUserValues method obtains information about user settings for the joystick. |
| GetVersions The IDirectInputEffectDriver::GetVersions method obtains version information about the force-feedback hardware and driver. |
| OpenAppStatusKey The IDirectInputJoyConfig8::OpenAppStatusKey method opens the root key of the application status registry keys, and obtains a handle to the key as a return parameter. |
| OpenTypeKey The IDirectInputJoyConfig8::OpenTypeKey method opens the registry key associated with a joystick type. |
| QueryInterface The IDirectInputEffectDriver::QueryInterface method determines whether the DirectInputEffectDriver object supports a particular COM interface. |
| QueryInterface The IDirectInputJoyConfig8::QueryInterface method determines whether the DirectInputJoyConfig object supports a particular COM interface. |
| Release The IDirectInputEffectDriver::Release method decreases the reference count of the DirectInputEffectDriver object by 1. This method is part of the IUnknown interface inherited by DirectInputEffectDriver. |
| Release The IDirectInputJoyConfig8::Release method decreases the reference count of the DirectInputJoyConfig object by 1. This method is part of the IUnknown interface inherited by DirectInputJoyConfig. |
| SendForceFeedbackCommand The IDirectInputEffectDriver::SendForceFeedbackCommand method changes the force-feedback state for the device. |
| SendNotify The IDirectInputJoyConfig8::SendNotify method notifies device drivers and applications that changes to the device configuration have been made. |
| SetConfig The IDirectInputJoyConfig8::SetConfig method creates or redefines configuration information about a joystick. |
| SetCooperativeLevel The IDirectInputJoyConfig8::SetCooperativeLevel method establishes the cooperation level for the instance of the device. The only cooperative levels supported for the IDirectInputJoyConfig8 interface are DISCL_EXCLUSIVE and DISCL_BACKGROUND. |
| SetGain The IDirectInputEffectDriver::SetGain method sets the overall device gain. |
| SetTypeInfo The IDirectInputJoyConfig8::SetTypeInfo method creates a new joystick type or redefines information about an existing joystick type. |
| SetUserValues The IDirectInputJoyConfig8::SetUserValues method sets the user settings for the joystick. |
| StartEffect The IDirectInputEffectDriver::StartEffect method begins the playback of an effect. If the effect is already playing, it is restarted from the beginning. |
| StopEffect The IDirectInputEffectDriver::StopEffect method halts the playback of an effect. |
| Unacquire The IDirectInputJoyConfig8::Unacquire method unacquires "joystick configuration mode". |
Interfaces
| IDirectInputEffectDriver These three methods allow additional interfaces to be added to the DirectInputEffectDriver object without affecting the functionality of the original interface. |
| IDirectInputJoyConfig8 IDirectInputJoyConfig8 interface contains methods that allow hardware developers who are writing property sheets to write and read information to and from the registry. |
