IMultiLanguage::ConvertString method
Converts the given source string from the source code page to the destination code page.
Syntax
HRESULT ConvertString(
[in, out] DWORD *pdwMode,
[in] DWORD dwSrcEncoding,
[in] DWORD dwDstEncoding,
[in] BYTE *pSrcStr,
[in, out] UINT *pcSrcSize,
[in] BYTE *pDstStr,
[in, out] UINT *pcDstSize
);
Parameters
pdwMode [in, out]
The storage for conversion context. The calling function should provide only storage that is initialized with zero at the first call to the method. The caller should not modify this value.dwSrcEncoding [in]
The code page identifier value for the source string. This value is equivalent to the uiCodePage member of the MIMECPINFO structure assigned to dwSrcEncoding.dwDstEncoding [in]
The code page identifier value for the destination string. This value is equivalent to the uiCodePage member of the MIMECPINFO structure assigned to dwDstEncoding.pSrcStr [in]
The address of the string to be converted.pcSrcSize [in, out]
A pointer to the buffer that stores the length of the source string, in bytes. 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 length of pDstStr, in bytes. When conversion is successful, the method returns the number of bytes copied to pDstStr to this buffer.
Return value
Returns one of the following values.
| Return code | Description |
|---|---|
| S_OK | Success. |
| S_FALSE | The specified conversion is not supported on the system. |
| E_FAIL | An error occurred. |
Remarks
Note that this method takes a pointer to a BYTE array for both the source string buffer and the destination string buffer. The size of this buffer is handled as the number of bytes for the inbound parameter and the outbound parameter.
