在MFC的CWinApp类的启动成员函数中,会一个SetRegistryKey函数,在注册表中为程序设置一个主键。配合WriteProfileInt等函数,对程序的配置文件进行读写。
SetRegistryKey(_T(""));//有这句,读写将会针对INI文件进行//指定自己的INI文件名,否则编译器将以程序名称命名INI文件free((LPTSTR)theApp.m_pszProfileName);theApp.m_pszProfileName = (LPCTSTR)malloc(256);_tcscpy ((LPTSTR)theApp.m_pszProfileName ,_T("ScaleWeight"));
写入配置文件信息,如下:
void SecondDig::OnCancel(){CRect rect;GetWindowRect(&rect);theApp.WriteProfileInt(_T("InitData"),_T("left"),rect.left);theApp.WriteProfileInt(_T("InitData"),_T("top"),rect.top);theApp.WriteProfileInt(_T("InitData"),_T("right"),rect.right);theApp.WriteProfileInt(_T("InitData"),_T("bottom"),rect.bottom);//AfxMessageBox(_T("cancel"));//DestroyWindow();CDialogEx::OnCancel();}
读取配置文件信息,如下:
BOOL SecondDig::OnInitDialog(){CDialogEx::OnInitDialog();CRect rect;int left   = theApp.GetProfileInt(_T("InitData"),_T("left"),0);int top    = theApp.GetProfileInt(_T("InitData"),_T("top"),0);int right  = theApp.GetProfileInt(_T("InitData"),_T("right"),0);int bottom = theApp.GetProfileInt(_T("InitData"),_T("bottom"),0);rect.left   = left;rect.top    = top;rect.right  = right;rect.bottom = bottom;this->MoveWindow(&rect,true);return TRUE;  // return TRUE unless you set the focus to a control// 异常: OCX 属性页应返回 FALSE}
