Hi,
I'm building a C# client app that allows a user to communicate with one or more existing users in a system via an email-like metaphor. I'd like to present the user with a text entry box that auto-completes on known email addresses, and allows multiple delimiter-separated addresses to be entered.

Hi,
Got an annoying problem here. I've got an NHibernate/Forms application I'm working through SVN. I made some of my own controls, but when I drag and drop those (or view some form editors where I have already dragged and dropped) onto some of my other controls, Visual studio decides it needs to execute some of the code I wrote, includ...

Hey all,
In the pursuit of elegant coding, I'd like to avoid having to catch an exception that I know well may be thrown when I try to validate that the Text field of a Textbox is an integer. I'm looking for something similar to the TryGetValue for Dictionary, but the Convert class doesn't seem to have anything to offer except exception...
I have legacy win.forms application written in pretty straightforward approach where forms communicate with DAL on UI events. For example there are textboxes: login/password, button - "Login" and a click-handler where business logic is implemented (DAL is asked to get user by id/password, if not null - than show next screen, if null - sh...
