Applications use the methods of the IDirectInputDevice7 interface to gain and release access to DirectInput devices, manage device properties and information, set behavior, perform initialization, create and play force-feedback effects, and invoke a device's control panel.
The IDirectInputDevice7 interface is obtained by using the IDirectInput7::CreateDeviceEx method. For an example, see Creating a DirectInput Device.
IDirectInputDevice7 supersedes the IDirectInputDevice and IDirectInputDevice2 interfaces used in previous versions of DirectX.
The methods of the IDirectInputDevice7 interface can be organized into the following groups.
| Accessing input devices | Acquire |
| Unacquire | |
| Device information | GetCapabilities |
| GetDeviceData | |
| GetDeviceInfo | |
| GetDeviceState | |
| Poll | |
| SetDataFormat | |
| SetEventNotification | |
| Device objects | EnumObjects |
| GetObjectInfo | |
| Device properties | GetProperty |
| SetCooperativeLevel | |
| SetProperty | |
| Force feedback | CreateEffect |
| EnumCreatedEffectObjects | |
| EnumEffects | |
| EnumEffectsInFile | |
| Escape | |
| GetEffectInfo | |
| GetForceFeedbackState | |
| SendForceFeedbackCommand | |
| WriteEffectToFile | |
| Miscellaneous | Initialize |
| RunControlPanel | |
| SendDeviceData |
The IDirectInputDevice7 interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECTINPUTDEVICE7 type is defined as a pointer to the IDirectInputDevice interface:
typedef struct IDirectInputDevice7 *LPDIRECTINPUTDEVICE7;
Windows NT/2000: Requires Windows 2000.
Windows 95/98: Requires Windows 95 or later. Available as a redistributable for Windows 95.
Header: Declared in dinput.h.
Import Library: Use dinput.lib.
