The software has two states,one is called configuration time,the other is run time.
In the configuration,user can inster a graphic object or activex control in a form.When swith to run time,the form is same as it is in the configuration time,and the objects inserted are active,e.g.a line begin to flash.
There are a lot of software like this in industry.In fact almost all the industrial HMI softwares are doing this.e.g.iFix,RSView32,InTouch...
Yes,in some way,it is like VB.We edit a form in the IDE,and when click the run button,the objects on the form is active.
What's the mechanism?
