LPARAM - A Data type of Windows used to pass message parameters to Windows Procedure. It is a 32 bit pointer which passes message as two parts i.e in High order(First 16 bits of 32 bits) and Low order(Second 16 bits of 32 bits).

  Where 
       High order is used to pass the height of the control and
       Low order is used to pass the width of the control

So if the height or width of the control exceeds 32762size, it shows error because

32767 is the highest number that can be represented in a signed 16bit integer.
