-----------------------------------------
your looking at the wrong part of code
if (!isAlias(encodingKey))
{
//
// Lets get the two values out of this key that we are
// interested in. There should be a code page entry and an
// IE entry.
//
// The Codepage entry is the default code page for a computer using that
charset
// while the InternetEncoding holds the code page that represents that charset
//
// unsigned long theType;
unsigned int CPId;
unsigned int IEId;
// mrg according to MS documentation, the length should include the NULL
terminator
theSize = sizeof(unsigned int) + 1;
if (::RegQueryValueExA
(
encodingKey
, "Codepage"
, 0
// mrg
// memory was overrun when theType was uploaded as it should have been type
LPDWORD (64 bits bytes not 32)
// , &theType
, NULL
, (LPBYTE) &CPId
, (LPDWORD) &theSize) != ERROR_SUCCESS)
{
::RegCloseKey(encodingKey);
continue;
