"error calling external object function open in line……" 这个提示表抄示open函数打开excel文档时参数出错，主要是括号内的参数excel文件的访问路径有问题，合适的访问方法应该是 “获取当前目录” + “\excel文件名” 构成袭open()函数的参数，但是在采用pb提供的获取路径的内部函数getcurrentdirectory()时就会出现问题，因为getcurrentdirectory()只能获取编译前的路径，当修目录时就会出现问题，所以务必保证所打开的open(...)参数内知的文件路径是正确的，建议使用系统API函数getcurrentdirectoryA（）获取路径，再加上“\excel文件名”来构造open()函数的参数，就道能解决这个问题。
