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.

Thanks for replies, and help.

I have took a tip from Patel. Not the same solution, but similar. I have add a clock on form, which is of course changing text. And on that label I have put a code on Label_textchanged. :-D

Solution 1

HireDateDateTimePicker_ValueChanged is a good place to put your line.

When you update your DTP with database value or manually, you'll get the updated days correctly in this case.

Solution 2

How about putting that code in the changed event of the HireDateDateTimePicker. That control is actually updated and accordingly does TextBox1 needs to be.

Good luck!
