XAudio2学习七之工程迁移错误
XAudio2学习七之工程迁移错误
徐冬冬
前面的几篇文章中的代码都是在公司电脑上创建和编写的，今天回到家中在网上下载了自己上传的源码后，
想用自己电脑上的VS2012打开并添加新功能，结果出问题了。
我自己电脑上也安装了Directx SDK，环境变量也添加了：
使用VS2012创建工程，选择的是Visual C++->General->Empty Project，输入工程名后，点击确定，
则创建成功。
然后我把sdk的include目录和Lib目录添加配置好。如下图所示：
配置好directx sdk后，我将上一篇文章中上传的源码，下载并解压后，将里面的文件添加到自己新创建的工程中，
编译时，出现了下列错误，百度了很久，也没查出个所以然来。

后来想了一会，发现我原来在公司时创建工程貌似都是选择的，win32 console project，然后选择建立空工程，
然后我就又新建了一个工程，将文件拷贝到新工程目录下，然后在VS添加到工程中，配置好sdk，编译，通过了。
然后就对比了一下两个工程的属性页配置的区别，发现区别是字符设置：
第二次新建（win32->Empty project）是Use Unicode Character Set，
第一次新建（general->empty project）是：Use Multi-Byte Character Set。
出现错误是因为编码方式不一样，从而导致类型有差别：LPSTR是ASCII编码，LPWSTR是Unicode编码。知道这个就好办了。
问题解决。
