关于MFC消息循环的问题？

[lc79]

在SDK中，我们可以在消息循环中加入些自己的代码，在MFC中可以吗？如果可以怎么弄呢？谢谢！！！

在vc ide里面ctrl+w

你可以看看CWinApp::Run(),你可能会重载它。但你要加什么代码?

我希望在空闲时间处理些代码，虽然可以用多线程，但我想多用几种方法试试！

重载CWinApp::OnIdle()
例子：
BOOL CMyApp::OnIdle(LONG lCount)
{
// In this example, as in most applications, you should let the
// base class CWinApp::OnIdle complete its processing before you
// attempt any additional idle loop processing.
if (CWinApp::OnIdle(lCount))
return TRUE;

// The base class CWinApp::OnIdle reserves the lCount values 0
// and 1 for the framework's own idle processing. If you wish to
// share idle processing time at a peer level with the framework,
// then replace the above if-statement with a straight call to
// CWinApp::OnIdle; and then add a case statement for lCount value
// 0 and/or 1. Study the base class implementation first to
// understand how your idle loop tasks will compete with the
// framework's idle loop processing.

switch (lCount)
{
case 2:
Task1();
return TRUE; // next time give Task2 a chance
case 3:
Task2();
return TRUE; // next time give Task3 and Task4 a chance
case 4:
Task3();
Task4();
return FALSE; // cycle through the idle loop tasks again
}
return FALSE;
}
