<> My Memory Game <> Lighting Keyboard's Locks ...

Hello everybody !
 

In this post, I will present my little game that I named "Memory Game". To illustrate the technique used in the game I will show the following steps :

- In fact, I use the keyboard's Locks because I want to make an exam for my memory if is it OK or not. Well, it's just a little introduction for fun purpose that's all...

  The following steps are :

- Using the keybd_event function in order to make Num Lock or Caps Lock or Scroll Lock lighted.

- Creating a function named "ReturnState". It's used for returning if the Keyboard's Locks are On or Off.

- A counter to counts the number of times when a keyboard's Lock is lighted.

- The rule of playing the game is presented as follow:

+ Run the Game and wait your chance, Look at the following picture :

 

+ Take a look at the choosen Keyboard's Lock which is Caps Lock and counting the numbers of times when Caps Lock is lighted.

 

+ When your death is arrived I mean when your time is over hhhh, this message will printed on screen :

 
+ If your answer is Correct, you will get "Congratulations !!!". Otherwise you will get this :
