The list below contains the HRESULT values that can be returned by Microsoft?DirectInput?methods and functions. Errors are represented by negative values and cannot be combined.
For a list of the error values each method or function can return, see the individual descriptions. Lists of error codes in the documentation are necessarily incomplete. For example, any DirectInput method can return DIERR_OUTOFMEMORY even though the error code is not explicitly listed as a possible return value in the documentation for that method.

} Return Values;
Constants
- DI_BUFFEROVERFLOW
The device buffer overflowed and some input was lost. This value is equal to the S_FALSE standard COM return value.
- DI_DOWNLOADSKIPPED
The parameters of the effect were successfully updated, but the effect could not be downloaded because the associated device was not acquired in exclusive mode.
- DI_EFFECTRESTARTED
The effect was stopped, the parameters were updated, and the effect was restarted.
- DI_NOEFFECT
The operation had no effect. This value is equal to the S_FALSE standard Component Object Model (COM) return value.
- DI_NOTATTACHED
The device exists but is not currently attached. This value is equal to the S_FALSE standard COM return value.
- DI_OK
The operation completed successfully. This value is equal to the S_OK standard COM return value.
- DI_POLLEDDEVICE
The device is a polled device. As a result, device buffering does not collect any data and event notifications is not signaled until the IDirectInputDevice8::Poll method is called.
- DI_PROPNOEFFECT
The change in device properties had no effect. This value is equal to the S_FALSE standard COM return value.
- DI_SETTINGSNOTSAVED
The action map was applied to the device, but the settings could not be saved.
- DI_TRUNCATED
The parameters of the effect were successfully updated, but some of them were beyond the capabilities of the device and were truncated to the nearest supported value.
- DI_TRUNCATEDANDRESTARTED
Equal to DI_EFFECTRESTARTED | DI_TRUNCATED.
- DI_WRITEPROTECT
A SUCCESS code indicating that settings cannot be modified.
- 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_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_MAPFILEFAIL
An error has occurred either reading the vendor-supplied action-mapping file for the device or reading or writing the user configuration mapping file for the device.
- DIERR_MOREDATA
Not all the requested information fit into the buffer.
- DIERR_NOAGGREGATION
This object does not support aggregation.
- DIERR_NOINTERFACE
The object does not support the specified interface. 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
This 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 DirectInput 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 could not 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_HANDLE
The HWND parameter is not a valid top-level window that belongs to the process.
- E_PENDING
Data is not yet available.
- E_POINTER
An invalid pointer, usually NULL, was passed as a parameter.
