help on creating a custom DBText component

rbuser

Hi!

I would like to have a custom component that let the user to make a
calculation on actual DBText or DBCalc value.
Calculation can be a Percent, Sum, Divisiom, etc...

For example, if DBText value is "100", and selected calculation is 20%,
result value will be "20".

Is there any similar component to start with?

Thanks!

Hi Santy,

Take a look at the current TppDBText and TppDBCalc classes located in the
ppCtrls.pas file for a starting point. From your description below, this
will be a component very similar to the DTText component with simple
calculations added on. Although the DBCalc component does perform similar
calculations, it is designed to accumulate values from the entire dataset
and give a value based on them.

Also, take a look at the demo located in the \Demos\RCL\... directory. This
shows how to create and add a custom component to ReportBuilder.
