我改了，编译无错误，但运行时又出问题了

在‘project setting’-》C/C++-》peprocessor 中的 _CONSOLE 改为 _WINDOWS

在 link-》project options 中把 /subsystem:windows 从console 改为windows

在project->settings->link选项卡(category为general)的project option编辑框中
就是最下面那有一堆配置参数的地方，把/subsystem:console 改为/subsystem:windows
你这个明显是直接抄过来的代码，正常应该是通过工程配置向导，一步一步设置的

谢谢各位大侠，还有点问题，我想把日期加上（在旁边加个数字框），而且可以用←、→、↑、↓键调节系统时钟（←键调节时针增加；→键调节时针减少；↑键调节分针增加；↓键调节分针减少）。要怎么改

[schlafenhamster]

'你这个明显是直接抄过来的代码'
不是的，有时别人给你一个cpp不带工程，如楼主的代码。这时你copy这个代码放一个cpp中如：
will.cpp然后C++打开这个文件，直接build all。
出现：error LNK2001: unresolved external symbol _main
时你就得改。

开来2个一样的贴？
pt[0].x -= pt[2].x / 2 ;
pt[0].y -= pt[2].y / 2 ;
fChange = (st.wHour != stPrevious.wHour ) || (st.wMinute != stPrevious.wMinute) ;
’-=，!=‘ 不要分开。
‘就可以了’
