   VK_ Constants?
  Hi, I am quite new to windows programming. I was tring to use the keyboard imput events: for exaple if the "Escape key" is pressed the program quits. the VK_ Constant is VK_ESCAPE.The problem is that my complier does not recognise the letter constants like VK_A or VK_B. I tried lowercases (VK_a, Vk_b) but it didn't work.the other contants, like VK_INSERT or VK_DELETE, work fine.Does anybody know why the letter constants don't work??Thanks in Advance,Merlino.   
  It's because you can use the actual characters, i.e.case 'A':  // do something with the A key.  break;They didn't waste time writing VK_A through VK_Z because of that.(Edit) Always remember to use the capitalized character in this case!   ;  Ok, Thanks man!   ;  Characters, numbers and punctuation (including special characters) aren't virtual.Relevant linky
