IMbnSms::SmsSendCdma 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.

Sends a message in CDMA format.

Syntax

HRESULT SmsSendCdma(
  [in]  LPCWSTR               address,
  [in]  MBN_SMS_CDMA_ENCODING encoding,
  [in]  MBN_SMS_CDMA_LANG     language,
  [in]  ULONG                 sizeInCharacters,
  [in]  SAFEARRAY             *message,
  [out] ULONG                 *requestID
);

Parameters

[in] address

A null terminated string that contains the receiver's phone number. The maximum size of the string is 15 digits.

[in] encoding

A MBN_SMS_CDMA_ENCODING value that specifies the data encoding.

[in] language

An MBN_SMS_CDMA_LANG value that specifies the language.

[in] sizeInCharacters

The number of encoded characters in the message. This can be different from the size of the message array.

[in] message

An array of bytes containing the encoded CDMA message.

The maximum size of this array is the CdmaShortMsgSize property of IMbnSmsConfiguration, however this can be no larger than MBN_CDMA_SHORT_MSG_SIZE_MAX (160).

[out] requestID

A pointer to a request ID issued by the Mobile Broadband service to identify this 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 device was 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_NOT_SUPPORTED)
 The device does not support sending SMS messages in the requested format. For example, if this function is called for a GSM device.

Remarks

This method can be used to send a SMS message for a CDMA device. However, this is only when the CDMA device supports sending SMS. A calling application can learn if the device supports this format by calling the GetInterfaceCapability method of IMbnInterface. It can then look for MBN_SMS_CAPS_TEXT_SEND in the smsCaps member of MBN_INTERFACE_CAPS.

The address parameter can be in either of these formats.

  • "+ <International Country Code> <SMS Service Center Number>\0"
  • "<SMS Service Center Number>\0"

This is an asynchronous operation that will return immediately. If the method returns without error, then the Mobile Broadband service will call the OnSmsSendComplete method of the IMbnSmsEvents interface.
