That first line is looking for a certain type of form being active. You create forms as part of the project. Each form is a class object. A class is a type, as are structures, and prety much any variable. So that first line is checking whether the active MDI form is either the MainForm or the FormLubricant.

2) A list is much like an array, except that it is much easier to add and remove things from a list than it is to do the same for an array. However, if you understand arrays, you understand lists. The only difference is the ease of changing a list.

3) DSAnalysisData is probably a class that wraps a dataset (since you mentioned the dataset). However, a dataset probably doesn't have enough functionality for the current program. The programmer wanted to be able to do things that a normal dataset can't do. Therefore, either they inherited from the Dataset class, or created a this class and gave it a Dataset as a member variable. This is closely related to item #4.

4) One of the ways that the programmer chose to extend the dataset is that they wanted the class to be able to read a file into the dataset. Therefore, they added the method ReadAnalysisHistoryFromLocalFile, which loads a file into the dataset.


I've got a suspicion that what I have written will present more questions, so I think I will leave it there for now.

I no longer see any code at all in this thread. Is that right?
