跟我学VBA，我这里专注VBA, 授人以渔。我98年开始，从源码接触VBA已经20余年了，随着年龄的增长，越来越觉得有必要把这项技能传递给需要这项技术的职场人员。希望职场和数据打交道的朋友，都来学习VBA,利用VBA,起码可以提高自己的工作效率，可以有时间多陪陪父母，多陪陪家人，何乐而不为呢？我的教程一共九套，从入门开始一直讲到程序的分发，是学习利用VBA的实用教程。这份API资料是随高级教程赠送的.
这讲我们继续学习VBA 64位API声明语句第017讲，这些内容是MS的权威资料，看似枯燥，但对于想学习API函数的朋友是非常有用的。
【分享成果，随喜正能量】34每个人在自己的时区都有自己的步程。不用嫉妒或嘲笑他人。他们都在自己的时区里，你也是！等待正确的行动时机，放轻松。你虽然没有领先但也没有落后。在命运为你安排的属于自己的时区里，一切都准时。
当学员学习到高级阶段，如果引用API，这个资料可以直接查到64位写法。大多数情况下我们是将低版本的程序文件升级到高版本，这时您就不必为如下的错误提示所困扰了：
