IMultiLanguage2::ConvertStringToUnicodeEx (Windows Embedded CE 6.0)

1/6/2010

This method translates the multibyte string from the specified code page to Unicode.


HRESULT ConvertStringToUnicodeEx( 
  DWORD* pdwMode,
  DWORD dwEncoding,
  CHAR* pSrcStr,
  UINT* pcSrcSize,
  WCHAR* pDstStr,
  UINT* pcDstSize,
  DWORD dwFlag,
  WCHAR* lpFallBack
);

pdwMode

[in, out] Address of storage for conversion context. A calling function should only provide storage that is initialized with zero at the first call to the method. The caller should not modify this value.

dwEncoding

[in] Specifies the code page identifier value for the source multibyte string. This value is equivalent to the uiCodePage member of the MIMECPINFO structure assigned to the dwEncoding parameter.

pSrcStr

[in] Pointer to the multibyte string that is to be converted.

pcSrcSize

[in, out] Pointer to the buffer that stores the length of the source string, in byte counts. If this is NULL, or if the length specified is -1, the method assumes that the string pointed to by the pSrcStr parameter is null-terminated. When the conversion is successful, the function returns the number of bytes processed to this buffer.

pDstStr

[in] Pointer to the string buffer where the conversion result is stored.

pcDstSize

[in, out] Pointer to the buffer that stores the memory allocated for the string pointed to by the pDstStr parameter, in character counts. When the conversion is successful, the function returns to this buffer the number of characters copied to the string.

dwFlag

[in] This parameter is currently ignored. It is recommended, however, that a caller set it to zero in case the parameter is not ignored in the future.

lpFallBack

[in] This parameter is currently ignored. It is recommended, however, that a caller set it to NULL in case the parameter is not ignored in the future.

The following table shows the possible return values for this method.

Value Description

S_OK

Success.

S_FALSE

The conversion specified is not supported on the system.

E_FAIL

An error has occurred.

The size of the multibyte string to be converted is specified with a byte count, while the size of the Unicode string returned is given in characters.
