CFileDialog 使用 OFN_ALLOWMULTISELECT 标志选择多个文件

CFileDialog dlg( TRUE, NULL, NULL, OFN_ALLOWMULTISELECT, NULL, NULL );
DWORD MAXFILE = 2562; //2562 is the max
TCHAR* pc = new TCHAR[MAXFILE * (MAX_PATH+1) + 1];
pc[0] = pc[1] = 0;

dlg.m_ofn.lpstrFile = pc;

int iReturn = dlg.DoModal();

nCount++;
}

str.Format("Successfully opened %d files/n", nCount);
AfxMessageBox(str);
}
