CFile和CFileDialog的结合...

下面是一个函数可以使用CFileDialog取得文件路径,然后用CFile打开的.

注意,CFile( ***** , "txt", ".txt")这里这个*****要注意, TRUE为打开框, FALSE为另存为框.

(其中,m_szEditText是已经绑定到一个CEdit里面的CString)

CString m_szTmp;
char buf[1000];
CFileDialog dlg(TRUE,"mdl","*.mdl");
if(dlg.DoModal()==IDOK) {
CFile mfile;
mfile.Open(dlg.GetPathName(), CFile::modeRead);
mfile.Read(buf,sizeof(buf));
m_szTmp = buf;
m_szEditText = m_szTmp;
mfile.Close();
}
UpdateData(FALSE);
