NET Framework any more than you have to know x86 assembly language to program Windows. But a rudimentary knowledge of CIL can really pay off when a method in the FCL doesn t behave the way you expect it to and you want to know why. You don t have the source code for the FCL, but you do have the CIL. In all, CIL includes about 100 different instructions.

To process input from noncharacter keys, windows 10 professional product key prices , you override OnKeyDown. To process input from character keys, windows 8.1 pro genuine product key , you generally override OnKeyPress instead. Why Because OnKeyPress receives a KeyPressEventArgs whose KeyChar property tells you what character was entered, taking into account the state of other keys on the keyboard such as Shift that affect the outcome.
