instance of an object”
this is what the code looks like

I have a form with an AdoDc control associated to a datagrid.
The AdoDC uses a "ConnectionString" such as
"Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data
Source=..."
this is where the problem begins. The data source will not be known until

Hi, please can anyone tell me if there is a way to navigate two adodc controls. I have a from with adodc1 and adodc2 - each linked to their own mdb table working perfectly. Is there any way by code that if you use the adodc1 control to navigate to the next record it will mirror this action in adodc2.
Would appreciate any insight, not even sure it can be done.
Regards
Werner

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
