In Windows 7 we have the concept of ApplicationID, which allows (among other things) to group several icons in the task bar. How can I change the ApplicationID of a running process from c#? I'm trying to make my WinForm app's icon group with another application. I've tried using Windows API Code Pack Library, sticking the following code in my Load event... but it didn't work. Suggestions?

TaskbarManager.Instance.ApplicationId = "MyAppID";    
Process[] p = Process.GetProcessesByName("OtherProcess");
TaskbarManager.Instance.SetApplicationIdForSpecificWindow(p[0].MainWindowHandle, "MyAppID");

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
