CFile about opening a file

1. Simple type from char to our CFile

#include <iostream>
#include <afx.h>
using namespace std;
int main ()
{
	//write
	CFile CFile;
	Const char* msg= "Ab.txt"; 
	wchar_t *wmsg = new Wchar_t[strlen (msg) +1]; Memory allocation
	mbstowcs (wmsg, MSG, strlen (msg) +1);

	CFile. Open (wmsg, cfile::modecreate | 
		Cfile::modereadwrite);
	Char pbufwrite[100];
	memset (Pbufwrite, ' a ', sizeof (Pbufwrite));
	CFile. Write (pbufwrite, MB);         
	CFile. Flush ();
	delete []wmsg;
	System ("pause");
}

2. Use the _t type directly without the char type

#include <iostream>
#include <afx.h>
using namespace std;
int main ()
{
	CFile CFile;
	tchar* pszFileName = _t ("F.txt");
	CFile. Open (pszFileName, cfile::modecreate | 
		Cfile::modereadwrite);
	Char pbufwrite[100];
	memset (Pbufwrite, ' a ', sizeof (Pbufwrite));
	CFile. Write (pbufwrite, MB);         
	CFile. Flush ();
	System ("pause");
}
