问题描述
CodeProject的成员您好，
我有一个项目，以及一个包含员工信息(姓名，城镇，生日，HireDate等)的数据库.我添加了自定义TextBox(运行中)，并在该TextBox上添加了代码:TexBox1.text = DateDiff("d", HireDateDateTimePicker.value, Now)
这是根据HireDate和Now计算工人在公司工作的天数.
我已将代码放在事件TextBox1_TextChanged上.但是，这意味着我需要在TextBox1中移动光标以应用更改.
我也尝试过使用MouseMove.它可以工作，但是如果我有一个庞大的数据库，那么应用程序将一直在读取MouseMove上的脚本，这样会使整个程序变慢.
需要别人给小费，例子等等...
预先感谢您对任何人的帮助.
Hello members of CodeProject,
I have a project, a database with employee information (name, town, birthday, HireDate, etc). I have add custom TextBox (on fly), and on that TextBox a code:TexBox1.text = DateDiff("d", HireDateDateTimePicker.value, Now)
which is calculating how many days worker is working in company from HireDate, and Now.
I have put code on event TextBox1_TextChanged. But, this means that I need to move cursor in TextBox1 to apply changes.
I have also try with MouseMove. It works, but if I would have a huge database, then application will all the time reading script on MouseMove, and by that will slow down entire program.
Need someone to give a tip, example, etc...
Thank you in advance for help to anyone.
