编译时无错，但在形成EXE时就会提示：
--------------------Configuration: chuangkou - Win32 Debug--------------------
Linking...
chuangkou.obj : error LNK2001: unresolved external symbol _LoasIcon
chuangkou.obj : error LNK2001: unresolved external symbol __imp__PlaySoundA@12
Debug/chuangkou.exe : fatal error LNK1120: 2 unresolved externals
执行 link.exe 时出错.

chuangkou.exe - 1 error(s), 0 warning(s)
我在书上抄的 ，是窗口的源程序，
用的是VC++6.0;
在书上看小写l和大写i一摸一样，根本分不开！
我是哪里错了啊 ！



[解决办法]
LoasIcon改成LoadIcon
