[Question]Control and Variables Displays as logic unit

negut

                                          We know from DGUS DG that the main conceptual logic entities which allow design of grafical interfaces are Touch Screen Controls and Variables Display.Let consider the case of a Control Programming as can be seen from the picture below ,In this picture ,under tabelar form , is one of Controls , A Slider Display with ID = 0x5A02.
What i am interested  : C program i can alter all Control parameters and the C souce code for this.
This is a first attemp to have actions in programatic mode over the data structure of a control or variables display.
Pls , if someoane can offer support for this.

What's your problem now？

Need an example code(as a begginer i am) which full control parameters of Touch Screen Control(Variables Display) or how is a Sys_write_VP(addre *, *buff, len) with all parameters of control.The idea is to use
typfdef struct{
char ID[2];
..........................................
} SliderDisplay
and iSys_write_flash via register 0x40  at different offsets the whole typedef.
I am sure that my sungle intention is understandable.
