Thank you sergeynikitin, and Mindtraveller. I feel privileged to get response from the senior members like you.
Sergey, I know I need to do lot of learning, and I’ll keep on working on that. I am an old C programmer who is returning to programming after more than a decade. So a lot to catch up, and for that I value each comment and information on this forum. During my last couple of weeks of starting into U++ (I chose U++ to restart programming because of its apparent simplicity), most of the time I am spending is on going through documentation and valuable forums and examples.
On Sergey’s solution to use EditField like in Vector<EditField> editline, my compiler is giving error, complaining about “cannot access private member declared in class” in EditCtrl.h
