• Visual C# Deep equivalence testing?

  Hi, hope you can help. If I create a class with some properties and fields and then instantiate two objects based on this class, I need some way of testing for equivalence. Since the == operator works on reference equivalence, this will not work for me. I need to do a field-by-field/property-by-property equivalence check. Ideally, this would be a deep test, recursively looking at sub-objects too. How is the best way to achieve this ...Show All

• Visual Basic Class Toolstrip Separator Visual Appearance

  Has anyone ever seen any modification of the graphics representation of a toolstrip separator I'm trying to come up with a representation indicating that a separator itself is selected on a toolstrip bar. So far, I can't see any programatic changes in background color or forecolor and adding a background image doesn't do anything. The visible = true and false properties work fine but it doesn't seem that anything else does whether I create a se ...Show All

  Hi, Ok, I have been working on a project in C# that manages a really simple database, that contains one table ('expenses') and only 6 columns ('id', 'title', 'description', 'amount', 'type', 'date').

• SQL Server OLAP Theory

  I'm trying to understand OLAP theory, especially with respect to allowing updates. I get that it's multidimensional, enterprisey and all that, but there doesn't seem to be a whole lot on the 'net that talks about OLAP without being intertwined with some OLAP product. Perhaps I've just been using the wrong search terms. What I'd like is something like this, which I've written up myself: https://ids.breuer.com/ds/1427 . People say to "not rei ...Show All
