Whenever I type in "DispatcherTimer" I get an error.You're probably missing a 'using' statement. Here's a tip: if DispatcherTimer is underlined after you type it, right-click on it. If "Resolve" is in the popup menu, then it is a reference problem that Visual Studio knows how to fix. Select it and choose either a using statement or fully qualified path that fixes it.
