IMLangConvertCharset::DoConversion Method

Converts the given string from the source code page of the Conversion Object to its destination code page.

Syntax

HRESULT DoConversion(
    BYTE *pSrcStr,
    UINT *pcSrcSize,
    BYTE *pDstStr,
    UINT *pcDstSize
);

Parameters

pSrcStr

[in] Address of the string that is to be converted.

pcSrcSize

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

pDstStr

[in] Address of the string buffer where the conversion result is to be stored.

pcDstSize

[in, out] Address of the buffer that stores the length, in bytes, of the buffer specified with pDstStr. 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:

S_OK	Success.
S_FALSE	The conversion specified is not supported. This happens when a newly detected code page is not supported on the system.
E_FAIL	An error occurred.

Remarks

Note that this method takes byte streams and byte counts regardless of the type of conversion (Unicode or multibyte), unlike IMLangConvertCharset::DoConversionFromUnicode and IMLangConvertCharset::DoConversionToUnicode.
