Hi,
I am trying to build an application that customizable without modify the code or re-compile. The customization involved I can think of as this moment as the following:

1. Decimal point of currency field shown on screen - some users prefer 2 decimal whereas some other use up to 4 decimal point in their business

2. Decimal point of Qty field - some user use integer as qty whereas some use 3 decimal point (for weighting item).

3. The width of field in report based on the setting 1, 2.

4. Variable field needed to be shown in report.

etc

How would you design and implement those as mentioned above in your application?

Thank you
