Constants
- DI_OK
- Success.
- DIERR_ACQUIRED 
- The operation cannot be performed while the device is acquired. 
- DIERR_ALREADYINITIALIZED 
- This object is already initialized. 
- DIERR_BADDRIVERVER 
- The object could not be created due to an incompatible driver version or mismatched or incomplete driver components. 
- DIERR_BETADIRECTINPUTVERSION 
- The application was written for an unsupported prerelease version of DirectInput. 
- DIERR_DEVICEFULL 
- The device is full. 
- DIERR_DEVICENOTREG 
- The device or device instance is not registered with DirectInput. This value is equal to the REGDB_E_CLASSNOTREG standard COM return value. 
- DIERR_EFFECTPLAYING 
- The parameters were updated in memory but were not downloaded to the device because the device does not support updating an effect while it is still playing. 
- DIERR_GENERIC 
- An undetermined error occurred inside the DirectInput subsystem. This value is equal to the E_FAIL standard COM return value. 
- DIERR_HANDLEEXISTS 
- The device already has an event notification associated with it. This value is equal to the E_ACCESSDENIED standard COM return value. 
- DIERR_HASEFFECTS 
- The device cannot be reinitialized because effects are attached to it. 
- DIERR_INCOMPLETEEFFECT 
- The effect could not be downloaded because essential information is missing. For example, no axes have been associated with the effect, or no type-specific information has been supplied. 
- DIERR_INPUTLOST 
- Access to the input device has been lost. It must be reacquired. 
- DIERR_INVALIDHANDLE 
- An invalid window handle was passed to the method. 
- DIERR_INVALIDPARAM 
- An invalid parameter was passed to the returning function, or the object was not in a state that permitted the function to be called. This value is equal to the E_INVALIDARG standard COM return value. 
- DIERR_MOREDATA 
- Not all the requested information fitted into the buffer. 
- DIERR_NOAGGREGATION 
- This object does not support aggregation. 
- DIERR_NOINTERFACE 
- The specified interface is not supported by the object. This value is equal to the E_NOINTERFACE standard COM return value. 
- DIERR_NOTACQUIRED 
- The operation cannot be performed unless the device is acquired. 
- DIERR_NOTBUFFERED 
- The device is not buffered. Set the DIPROP_BUFFERSIZE property to enable buffering. 
- DIERR_NOTDOWNLOADED 
- The effect is not downloaded. 
- DIERR_NOTEXCLUSIVEACQUIRED 
- The operation cannot be performed unless the device is acquired in DISCL_EXCLUSIVE mode. 
- DIERR_NOTFOUND 
- The requested object does not exist. 
- DIERR_NOTINITIALIZED 
- The object has not been initialized. 
- DIERR_OBJECTNOTFOUND 
- The requested object does not exist. 
- DIERR_OLDDIRECTINPUTVERSION 
- The application requires a newer version of DirectInput. 
- DIERR_OTHERAPPHASPRIO 
- Another application has a higher priority level, preventing this call from succeeding. This value is equal to the E_ACCESSDENIED standard COM return value. This error can be returned when an application has only foreground access to a device but is attempting to acquire the device while in the background. 
- DIERR_OUTOFMEMORY 
- The DirectInput subsystem couldn't allocate sufficient memory to complete the call. This value is equal to the E_OUTOFMEMORY standard COM return value. 
- DIERR_READONLY 
- The specified property cannot be changed. This value is equal to the E_ACCESSDENIED standard COM return value. 
- DIERR_REPORTFULL 
- More information was requested to be sent than can be sent to the device. 
- DIERR_UNPLUGGED 
- The operation could not be completed because the device is not plugged in. 
- DIERR_UNSUPPORTED 
- The function called is not supported at this time. This value is equal to the E_NOTIMPL standard COM return value. 
- E_PENDING 
- Data is not yet available.
