CString TCHAR的互相转换

CString－>TCHAR*的转化可以用函数GetBuff()

函数原型为：LPTSTR GetBuffer( int nMinBufLength );
CString str("CString");
TCHAR* szMsg = new TCHAR[100];
//其参数为CString字符串的长度
szMsg = str.GetBuffer(str.GetLength());
str.ReleaseBuffer();
delete []szMsg;
szMsg = NULL;

TCHAR*－>CString的转化

TCHAR szTchar[18] = L"TCHAR";
CString str;
str.Format(_T("%s"),szTchar);
