IMultiLanguage2::ConvertStringToUnicode method

Translates the source string from the specified code page to Unicode.

Syntax

HRESULT ConvertStringToUnicode(
  [in, out] DWORD     *pdwMode,
  [in]      DWORD     dwEncoding,
  [in]      __wchar_t *pSrcStr,
  [in, out] UINT      *pcSrcSize,
  [in]      WCHAR     *pDstStr,
  [in, out] UINT      *pcDstSize
);

Parameters

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

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

• pSrcStr [in]
  A pointer to the multibyte string to be converted.

• pcSrcSize [in, out]
  A 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 API assumes pSrcStr is null-terminated. When conversion is successful, the method returns the number of bytes processed to this buffer.

• pDstStr [in]
  A pointer to the string buffer where the conversion result is stored.

• pcDstSize [in, out]
  A pointer to the buffer that stores the memory allocated for pDstStr, in character counts. When conversion is successful, the method returns the number of characters copied to pDstStr to this buffer.

Return value

Returns one of the following values.

Remarks

Note that 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.
