LONG is actually 4 bytes, a DWORD. To show it in a MessageBox, you need one of the dword2Ascii functions, for example the str$(eax) macro.

include \masm32\include\masm32rt.inc

.code
start:   invoke GetTickCount
   push eax
   invoke Sleep, 500
   invoke GetTickCount
   pop ecx
   sub eax, ecx
   MsgBox 0, str$(eax), "Milliseconds:", MB_OK
   exit
end start
