IMbnRegistration::SetRegisterMode method (mbnapi.h)

  • Article

Important

Starting in Windows 10, version 1803, the Win32 APIs described in this section are replaced by the Windows Runtime APIs in the Windows.Networking.Connectivity namespace.

Sets the registration mode for the device.

Syntax

HRESULT SetRegisterMode(
  [in]  MBN_REGISTER_MODE registerMode,
  [in]  LPCWSTR           providerID,
  [in]  ULONG             dataClass,
  [out] ULONG             *requestID
);

Parameters

[in] registerMode

An MBN_REGISTER_MODE value that specifies the new registration mode.

[in] providerID

A string that specifies the provider ID of the network provider to which to register. Must be NULL when registerMode is MBN_REGISTER_MODE_AUTOMATIC.

[in] dataClass

A bitwise combination of OR MBN_DATA_CLASS values that specify the preferred data access technologies for the connection. The Mobile Broadband service will register the highest available data class technology from this list. If no data class from this list can be registered to, then the Mobile Broadband service will register to the best available data class.

[out] requestID

A request ID set by the Mobile Broadband service to identify this asynchronous request.

Return value

This method can return one of these values.

Return code Description
S_OK
 The method completed successfully.
HRESULT_FROM_WIN32(ERROR_SERVICE_NOT_ACTIVE)
 The Mobile Broadband service is not running on this system.
E_HANDLE
 The interface is invalid, most likely because the Mobile Broadband device has been removed from the system.
HRESULT_FROM_WIN32(ERROR_NOT_FOUND)
 The interface is invalid. Most likely the Mobile Broadband device has been removed from the system.
HRESULT_FROM_WIN32(ERROR_INVALID_STATE)
 There is already an active network connection. The registration mode cannot be changed while there is an already established data connection. The calling application should first disconnect the connection and then try changing registration mode. If the device is already in the requested mode and connected to the requested provider, then the return code will be S_OK.

Remarks

The SetRegisterMode method can be used to set a device into automatic or manual network selection mode. For manual registration mode the network ID to which the device should register is supplied in providerID.

Support for manual registration mode is optional and the application should verify that the device supports manual registration by checking for MBN_CTRL_CAPS_REG_MANUAL in the interfaceCaps parameter filled by the GetInterfaceCapability method of IMbnInterface. If an application sets the manual registration mode and it is not supported by the device, then this call will return HRESULT_FROM_WIN32(ERROR_NOT_SUPPORTED).

SetRegisterMode is asynchronous and will return immediately. If there is no error, on completion of the operation, the Mobile Broadband service will call the OnSetRegisterModeComplete method of IMbnRegistrationEvents.
