If Control.ModifierKeys = Keys.Shift Or Control.ModifierKeys = Keys.Control Then
    ' Shift, Ctrl, or Shift+Ctrl is being pressed
Else
    ' Neither Shift nor Ctrl is being pressed
End If

The following will return True or False depending on whether the key is pressed at that moment. From the wording of your question, I assume you are not asking about event handling, which is what the other answers have addressed.

My.Computer.Keyboard.ShiftKeyDown
My.Computer.Keyboard.CtrlKeyDown

I assume you want to see on whole application. To do this, forms or controls have "keypress" or "keydown" events. You can check them with those events. Click events tab and you'll see them

Check that link : http://msdn.microsoft.com/en-us/library/system.windows.forms.keyeventargs.aspx#

It's about KeyEventArgs Class with some examples how to detect shift/ctrl keypress etc.
