编译连接错误汇总：
--------------------------------------------------------------------------------
症状:
d:\work\feature.h : warning C4819: The file contains a character
that cannot be represented in the current code page (936).
Save the file in Unicode format to prevent data loss
--------------------------------------------------------------------------------

错误原因：字符编码与你的code page 不符，但并不像它所提示的改为unicode 编码。
解决办法：如果你使用的是multibyte 字符集，将文件编码改为cp936 解决


--------------------------------------------------------------------------------
症状：
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>d:\work\myvoice\client\client\wavefile.cpp(123) : error C2664: 'mmioOpenW' : cannot convert parameter 1 from 'char *' to 'LPWSTR'
--------------------------------------------------------------------------------
错误原因： VS2005默认的设置是采用UNICODE字符集，其函数调用都是W()型调用。
解决办法：改为函数调用采用ansi型，即工程属性->配置属性->常规->字符集 项 选择“使用多字节字符集”

1>D:\work\myvoice\client\Debug\client.exe : fatal error LNK1120: 7 unresolved externals
--------------------------------------------------------------------------------
错误原因：缺少dll 文件
解决办法：
project property->linker->general->additional library directory: 填库路径
project property->linker->input->additional dependencies: 填库名称

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
错误原因： 连接了一个外部调试版dll, 结果出现 libcmtd 与MSVCRTD 冲突，
这说明dll 中已经有一套了，系统默认连接库与之重复包含，重复定义了。

解决办法: 只要忽略 MSVCRTD 或者 LIBCMTD 即可。
project property->link->input->ignore specific library,
添加MSVCRTD来忽略它. 重新编译。通过。
或者添加LIBCMTD来忽略它 ,重新编译.通过
单步跟踪，还可以单步跟踪到dll 中去(需要指定源代码位置）。
只不过这种方式虽可调试dll 代码， 但在vc环境中浏览阅读dll 代码不太方便，
正确的做法还是在dll 工程中调试dll，有浏览信息。
