| 摘 要： | Visual basic随机文件记录含有汉字时,会发生读出记录不全的错误.究其原因,即记录的字段必须为定长的字符串,当写入或读出记录的长度少于定长的字符串长度时,会用空白来填充记录中后面的空间,用VB的内部函数RTrim或Trim都不能除掉这个空白.在此通过调用一个自定义函数,给出解决这一问题的方法.

| Abstract: | When random files in Visual Basic contain Chinese characters,mistake named recorder read partially would(occur.) The reason for that can be attributed to the fact that the recorded field must be a fixed-length string,so when the length of the(recorder) in read-in or read-out process is less,further space left in the recorder will be fulfilled by blank content,VB's intrinsic function Rtrim or Trim both are unable to eliminate the blank.Therefore,this essay will introduce a method of transfering a self-defined function to cope with the problem. |
