QuestionBuffer data size Pin
_Flaviu7-Apr-15 21:46
member_Flaviu7-Apr-15 21:46 
Hi all. I have a doubt: how ulSize data buffer size should be:
CString sValue;
ULONG ulSize = _MAX_PATH;
lRet = RegQueryValueEx(hKey, NULL, NULL, NULL, (BYTE*)sValue.GetBuffer(_MAX_PATH), &ulSize);
sValue.ReleaseBuffer();
or
CString sValue;
ULONG ulSize = _MAX_PATH * sizeof(TCHAR);
lRet = RegQueryValueEx(hKey, NULL, NULL, NULL, (BYTE*)sValue.GetBuffer(_MAX_PATH), &ulSize);
sValue.ReleaseBuffer();

I guess that ulSize should be _MAX_PATH * sizeof(TCHAR); like in the second code ... but I am not sure ... can you tell me how is right ?

Thank you.
