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012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】222苦非苦,乐非乐,只是一时的执念而已。执于一念,将受困于一念;一念放下,会自在于心间。物随心转,境由心造,烦恼皆由心生。有些人,有些事,是可遇不可求的,强求只有痛苦。既然这样,就放宽心态,顺其自然。无论何时何地,都要拥有一颗安闲自在的心,保持豁达的心态。
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:
