Using ideas provided by some of you I was able to figure out how to get the
names of the parameters fields of a crystal report specified at run time.
The code below just basically puts the data into a comboBox. One thing I
noticed, however, is that this method shows me both the parameters used by
the main report and parameters used by the sub-report(s).

selectcommand? But when I use these database such as Pub or Northwind in SQL
Server to create dataadapter, it can auto create updatecommand and
deletecommand. Why?

and re-invoking the update procedure. Is there something else I need to do
to add param values inline with the param...

Hello folks,

This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
