LPWSTR free memory

LPWSTR tmpValue= new WCHAR[1024];

delete[] tmpValue;

convert from BSTR to wstring

wstring sSlideName = SysAllocString(slideName);

phep so sanh BSTR

if (!wcsncmp(FontType, L"fontColor", 64)) {}

List - Iterator

for(list::iterator it=m_pptInitialSlideIDListNew.begin(); it!=m_pptInitialSlideIDListNew.end(); it++)
{
int iSlideIDCurrent = *it;
}
