I want to be able to persist a couple of custom objects, like the 'User', some 'Roles', and whether or not they are authenticated. When a user starts the app, the get some screens, but must authenticate to get others. What would be the best way to persist that info. I am an ASP.NET guru ;-), but not a Windows Forms genius. Thanks. Hi Smith, Is this a windows forms application If yes then you can set access privileges set for each screen in the backend. When a user clicks on a screen, in t ...Show All

• Visual Studio 2008 (Pre-release) Simple ListBox template change, big performance degradation

  I have a ListBox in my application showing around 200 items where the items use their respective data templates.  The performance was good enough. Because I needed to put some status information embeded in the ListBox, I modified the ListBox Template to include a TextBlock at the top.  To my surprise, when I did that, the performance of the ListBox was greately reduced!! It's 10x slower or more on many aspects: when populating, when selecting an item, when scrolling, etc. Does anybody know why adding a DockPanel and a TextBlock makes it so slow The two styles are listed bellow. Style1 keeps the listbox fast. Style2 mak ...Show All

• .NET Development ArrayList.Add problem - values and references

  Hi, I'm having a problem with my code. I have an Array called moves of length four that contains ArrayLists, each of which I modify according to user input. Each time input is complete I want to save a copy of the moves so that I can go back and retrieve previous entries.
