| Namespace | Windows.Devices.Midi2.ServiceConfig |
|---|---|
| Type Name | MidiServiceConfigSaveResult |
| Type | WinRT Enumeration (a 32-bit unsigned or signed integer) |
| IDL | MidiServiceConfigSaveResultEnum.idl |
Enum which indicates whether a configuration was successfully written to the Windows MIDI Services configuration file, and if not, what went wrong. Every failure here is one which can be reported to the customer and acted upon.
Sending a configuration to the service and saving it to the configuration file are separate operations. See MidiServiceTransportPluginConfigManager.SaveUpdate for why.
| Property | Value | Description |
|---|---|---|
Success |
0x00000000 |
The configuration was saved |
ErrorNotPersistable |

The supplied config json is missing |
ErrorProcessingConfigJson |
0x00000259 |

No configuration file is registered on this PC, so there is nowhere to save to |

0x000002BD |
The file on disk is not valid JSON. It is left untouched so its contents can still be recovered |
ErrorAccessDenied |
0x000002BE |

ErrorConfigFileBusy |
0x000002BF |
Another program is writing the file. Retrying is reasonable |

ErrorVerificationFailed |
0x000002C1 |
The file was written but did not read back as valid JSON, so the previous contents were restored |

An unexpected error prevented the configuration from being saved |
