windows 核心编程第五版

第一章 错误处理


1.调用系统API时候仔细查看MSDN返回值含义。


2.函数调用失败后，可以立即调用 GetLastError来查看错误码。


3.可以利用Visual Studio 自带工具 Error Lookup 来查看错误码对应的含义。


4.在调试的时候在Watch 窗口中选择一行，然后输入$err,hr。对于错误码和错误信息都能更有效的查看。


5.定义自己的错误码：有时候我们会写函数提供给别人调用，这样就需要向别人指出错误。为了指出错误，只需要设置线程上的一个错误代码，然后另自己的函数返回FALSE,INVALID_HANDLE_VALUE,NULL 或者其它合适的值。为了设置线程的上一个错误代码，只需要调用 :

VOID setLastError(DWORD dwErrcode);


尽量使用WinError.h 中现有的代码来表示错误码。如果都不能很好的反应自己想要表达的错误信息，就可以自己创建错误码，错误代码是一个32位数。唯一需要注意的是29位为1（表示用户自定义错误）

31-30

关闭模态对话框，并且将参数作为父对话框调用的返回值。

(2)  DestroyWindow();  ::PostQuitMessage(0);

DestroyWindow 关闭非模态对话框。 退出消息循环，真正结束进程。有不少程序窗口关闭，但是不等于退出运行。
