Hello Brother Esgici,
I am very much happy to talk to you
Thanks a lot for your help. It works fine.
But, I found problem with common copy-and-paste using Ctrl+V, not by using value property of numeric textbox.
How I tested:
1. Copy (using Ctrl+C or System.clipboard := ...) any numerical value (eg., 88,89) to clipboard from anywhere (eg., from Notepad).
2. Now set focus to any of your existing app's numeric textbox control having decimal point picture, eg., "999999.9999".
3. Now use Ctrl+V to paste the value from windows clip board.
In my case, I found problem.
(I reported this problem in BUG Reports section, because I think it will be easier for Roberto to find it from here. As he is very busy, he may not have time to see the problem in Help Section, where I first asked help for this problem.)
I understand the code I posted in Help Section is mis-leading. Problem is general, not related to the specific code. Sorry
Thank you again for your help
