PathFileExists用法－－使用#include <shlwapi.h>

BOOL PathFileExists(LPCTSTR pszPath);

Determines if a file exists.

---经检测，该函数可以检测文件或目录是否存在！

Remarks

This function tests the validity of the file and path. It works only on the local file system or on a remote drive that has been mounted to a drive letter. It will return FALSE for remote file paths that begin with the UNC names \\server or \\server\share.
It will also return FALSE if a mounted remote drive is out of service.

为了使用PathFileExists()，必须包含头文件"shlwapi.h"，范例代码如下：

编译后，却发现一个错误：error LNK2001: unresolved external symbol
__imp__PathFileExistsA@4

网上搜索了下，发现是因为没有添加相应的lib。添加lib的方法网上有不少，这里使用下面的方法：

或者在文件头部加入这行代码： #pragma comment(lib,"shlwapi.lib")





这样，就可以通过编译了！
