INapComponentConfig2::InvokeUIFromConfigBlob method

Note  The Network Access Protection platform is not available starting with Windows 10

The InvokeUIFromConfigBlob method is implemented by system health validators (SHVs) as needed to load the configuration of a remote or local machine in memory and display a UI that allows manipulation of the configuration data. The configuration component must support the usage of INapComponentConfig through DCOM.


HRESULT InvokeUIFromConfigBlob(
  [in, unique] HWND   hwndParent,
  [in]         UINT16 inbCount,
  [in]         BYTE   *inData,
  [out]        UINT16 *outbCount,
  [out]        BYTE   **outdata,
  [out]        BOOL   *fConfigChanged


hwndParent [in]

A handle to the parent or owner window. A valid window handle must be supplied.

inbCount [in]

The size, in bytes, of inData.

inData [in]

A pointer to a buffer that stores the initial configuration data. This data is exported from the remote or local machine.

outbCount [out]

The size, in bytes, of outdata.

outdata [out]

A pointer to a buffer that stores configuration data changed by the SHV configuration user interface. This data is imported by the remote or local machine.

fConfigChanged [out]

A pointer to a BOOL that is set to TRUE if the configuration was changed during the UI operation and FALSE otherwise.

Return value

Returns S_OK if successful, or one of the standard Windows error codes.


If used for a local machine, this function can be used for per policy SHV configuration. It provides a way to invoke an SHV UI and edit an existing SHV configuration.
