推荐答案

在执行某些任务时有效显示和更新进度栏所需的内容可以在任何给定的时间告诉您:

1)到目前为止，您处理了多少个
2)要处理多少?


因此，对于数据库行，首先要获取必须进入文本文件的所有行的计数，然后循环遍历每一行，并使用以下公式在每次循环迭代中更新进度条的值:

[number of rows processed until now] / [number of rows to be processed] * 100

希望对您有帮助

Hi,
What you need to effectively display and update a progress bar while doing some task is be able to tell at any given time:

1) how much have you processed until now
2) how much is it to be processed


So in the case of database rows, first start by getting a count of all the rows you have to get to the text file, then loop through each of them and update the value of the progress bar in each loop iteration by using the formula:

[number of rows processed until now] / [number of rows to be processed] * 100

I hope this helps
