• DKB System.Timers.Timer high resolution problem (C#)

  I want to use System.Timers.Timer in my project as a metronom with the resolution of approx. 1ms interval value. When i tried, it works fine up to 10ms, but below that value, it doesn't work. in my sample application, i am using a count value which increases every tick and when the count reaches the value of 100, i invoke a function which updates the label1. When i use the interval as 10, label1 updates every 1 second as expected but when i reduce the interval value, the time for updating the label1 doesn't decrease. For example, when i set interval to 1ms, it still takes 1 second to update label1. Does System.Timers.Timer allows interval below 10 Or is there any timer which does this in .NET framework PS: I didnt set the Syncroni ...Show All

• Samoyed generics and static methods question

Is there a way to call static methods in the T class so I can streamline this I have two static methods in T named GetItem and SaveItem that I would like to invoke by something like T.GetItem(astring) and T.SaveItem(t).
