HRESULT Error Codes
The 32bits in an HRESULT error code have meanings, allowing the reader to gain additional insights into the error.
Of note:
The 32nd bit (the top bit) indicates if an error occurred or not. This is why errors are 0x8xxxxxxx.
The 16-26 bits are the Facility - the originating API (Win32, CLR, XAML, etc.).
The 0-15 bits are the (Error) Code.
Common NULL Facility Error Codes
| Name | Description | Value |
|---|---|---|
| S_OK | Operation successful | 0x00000000 |
| S_FALSE | Operation successful but returned no results | 0x00000001 |
| E_ABORT | Operation aborted | 0x80004004 |
| E_FAIL | Unspecified failure | 0x80004005 |
| E_NOINTERFACE | No such interface supported | 0x80004002 |
| E_NOTIMPL | Not implemented | 0x80004001 |
| E_POINTER | Pointer that is not valid | 0x80004003 |
| E_UNEXPECTED | Unexpected failure | 0x8000FFFF |
Common Win32 Facility Error Codes
These are built by passing a System Error Code to HRESULT_FROM_WIN32
| Name | Description | Value |
|---|---|---|
| E_ACCESSDENIED | General access denied error | 0x80070005 |
| E_HANDLE | Handle that is not valid | 0x80070006 |
| E_INVALIDARG | One or more arguments are not valid | 0x80070057 |
| E_OUTOFMEMORY | Failed to allocate necessary memory | 0x8007000E |
