Open pathname For mode[Access access][lock]As[#]filenumber[Len=reclength] 底层实现上应该也是调用Windows API。 而很多没有的功能,也只是VBA没有帮忙实现,需要我们自己去调用Windows API实现罢了。 我原来刚接触API的时候,基本上就是在网上查,然后复制代码,对于代码的原理几乎不明白,出了问题也很难发现。
VBA Length of String – Example #2 Suppose, I have the word“NULL” and I want to find out the number of characters in this text string i.e. for this, with the help ofVB LENfunction macro code, I can find out. Step 1:In the VBA editor, I have given a name asLENGTH()after ...
语法:Open pathname For mode [Access access] [lock] As [#]filenumber [Len=reclength] 其中access、lock、reclength为可选参数,一般不用。 mode 指定打开文件的方式。有5种: Input:以输入方式打开,即读取方式。 Output:以输出方式打开,即写入方式。
