问题 I am developing a simple serial data viewer that will be used to watch the data being transmitted to one of a computer's serial ports. I wrote a test application using C# and WPF; it simply places the most recently read line into a textblock. However, it skips every-other line.

问题 This supposedly easy task gave me some headache. I simply want to let the user enter any text that succeeds float.TryParse into a Textboxish control.

Digging around on the net brought some interesting ideas, but
