For Each oProducts As Products In oAssigment.ProductsList
For Each oproduct As Product In oProducts.ProductList
For Each cr As Criterias In oproduct.CriteriaList
cr.CrPropName = "Product Name" 'some object property name
cr.CritCode = "PN"
cr.crPropValue = "" ' Value of property "Product Name"

It is all made to have different properties of some object depending on options set in text file. It is only a sample o usage.
conditions:
Criterias on applications start is same for all objects (=Product) i want to read.
Every time on start, application read options file where is defined few property names and codes (values i want get from objects). So every run can be initiated different quantity of properties to read. It means i can not have hard-coded names of properties.
Someone can advice me how to predefine "CrPropName" and "CritCode" on app start so many times how much property names defined in options and after that populate it so many times as how many objects exist from which i read these property values.
p.s. I am not very professional at coding and sorry for my language
