CWinApp类中提供了一组用于读写应用程序配置的方法:
GetProfileInt
WriteProfileInt
GetProfileString
WriteProfileString
可方便的用于读写应用程序配置。
用VC++的向导建立MFC项目之后,在InitInstance中可以看到这样的语句:
SetRegistryKey(_T("应用程序向导生成的本地应用程序"));
该函数将为以上提到的几个方法建立工作环境,此时如果用WriteProfileInt写入数据,将会
被写入到如下注册表位置:
HKEY_CURRENT_USER\Software\应用程序向导生成的本地应用程序\应用程序名称\
如果在InitInstance中不执行SetRegistryKey,则用WriteProfileInt写入数据时,将写入到
%windir%\应用程序名称.ini中。
则对于:
WriteProfileInt("section","val1",10);
将在注册表中如下路径写入数据:
[HKEY_CURRENT_USER\Software\清风居\测试应用程序\section]
"val1"=dword:0000000a
注:“测试应用程序”是应用程序的名称。
则对于:
WriteProfileInt("section","val1",10);
将在“%windir%\测试应用程序.ini”中写入:
[section]
val1=10
//改变大小时
void CMyDlg::OnSize(UINT nType, int cx, int cy)
if (m_bInitDialog && cx<nX && cy<nY)
{
//保存当前大小位置
CRect rcWindow;
GetWindowRect(&rcWindow);
theApp.WriteProfileInt("Settings","left",rcWindow.left);
theApp.WriteProfileInt("Settings","top",rcWindow.top);
theApp.WriteProfileInt("Settings","right",rcWindow.right);
theApp.WriteProfileInt("Settings","bottom",rcWindow.bottom);
}
//移动窗口时
void CMyDlg::OnMove(int x, int y)
{
if (m_bInitDialog && x!=0 && y!=0)
{
//保存当前大小位置
CRect rcWindow;
GetWindowRect(&rcWindow);
theApp.WriteProfileInt("Settings","left",rcWindow.left);
theApp.WriteProfileInt("Settings","top",rcWindow.top);
theApp.WriteProfileInt("Settings","right",rcWindow.right);
theApp.WriteProfileInt("Settings","bottom",rcWindow.bottom);
}
}
//初始化
BOOL CMyDlg::OnInitDialog()
{
CRect rcWindow;
rcWindow.left=theApp.GetProfileInt("Settings","left",200);
rcWindow.top=theApp.GetProfileInt("Settings","top",120);
rcWindow.right=theApp.GetProfileInt("Settings","right",800);
rcWindow.bottom=theApp.GetProfileInt("Settings","bottom",600);
MoveWindow(&rcWindow);
}
在MFC中用WriteProfileInt等方法保存应用程序配置
