功能代码：
1 /*========================================================================
2 功能:获取文件版本信息.
3 说明:要使用此函数必需在程序中加入
4 #pragma comment(lib, "Version.lib ")
5 ----------------------------------------------------------------------------
6 参数:lpszFileName=程序文件名,如果为空则是获取当前运行程序的版本信息

2 CString sFileVersion = GetProductVersion(sFilePath);
3 if (sFileVersion.CompareNoCase("Error") == 0)
4 {
5 printf("Get File Version unsuccessful!\n");

10 printf("Get File Version successful!\n");
