  - by Mridang Agarwalla

C:\Program Files --- C:\ and C:\ --- C:\ If the directory doesn't have a parent directory, it returns the directory itself. The question might seem simple but I couldn't dig it up through Google. Thanks.

  What is the best method of storing an Enum in a Database using C# And Visual Studio and MySQL Data Connector.

  I am trying to understand what is WCF, but can't get a visual understanding of how it adds value (reading msdn does'nt help). I have worked with COM in the past, and I know about webservices. Can someone shed some light on what is WCF and its pros and cons (maybe how it relates to COM or replaces COM etc)? Links to reference web sites would also be great. Thanks

  Not that significant, but annoying to no end. Why does matlab has no small phi (\varphi) symbol ? It has pretty much all other symbols LaTeX offers, but not this one. Why ? I may be wrong of course, in which case would be delighted if someone could prove me wrong...

• How to use WatiN to control browser tabs?

  - by Dmitri Nesteruk

  I want to use WatiN with IE in a parallel setting, i.e. work with dozens/hundreds of pages at once. I've tried sticking it into a Parallel.For loop only to see the whole thing crash, so I'm thinking opening multiple tabs in the browser is the way to go. Can someone suggest how this can be done using WatiN (or just some IE-related API) or whether there's a better way? TIA!

• Avoid hardcoding iPhone screen size with programmatic view creation

  - by miorel

  Hi, I was looking up how to create a view programmatically and found the following example code: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; This works great, except I don't like that it hardcodes the size of the screen. Is there a way to look up the size of the screen? An important point someone brought up is that if the app is running during a phone call then the screen will be slightly smaller because of the green "return to call" bar.
