Default Transferring data between functions

i have three PictureBoxes, background1,background2 and background3.firstly i initialise a var x=1.when the user clicks the PictureBoxes, it calls a function that changes the value of x.but when i use this var in another function, it remains as its original value.so how do i get the new value of x across to this other function?

you should try to use pointers
save the addres of x into pointer pX, and then just pass the pointer from function to function, so you can change the value of x through any function

If you prefix C# method arguments with "ref " the argument will pass the pointer instead of an instance.
