This is usually done using Interrupt 33h. If you have access to a copy
of Ralf Brown's Interrupt list take a look there. The Interrupt list can
be found on Simtel Net in the msdos/info/ directory via the Internet.
Here's a little something to get you started.
'$INCLUDE: 'qbx.bi'  ' For Call Interrupt, QB45 use 'qb.bi'
DECLARE SUB GetMouseInfo (Status%, MCol%, MRow%)
DECLARE SUB ShowMouse ()
DECLARE SUB HideMouse ()
DIM SHARED Regs AS RegType
CONST True = -1
CONST False = NOT True
'Put your Code Here.
'***************************************************************
' Gets the Button Status (Which Button Pressed) and the
' Location (Row/Col) of the Mouse Cursor. Location is in Pixels.
' Screen 12 80x30  Col/8 Row/16 For Text Position
'
'

'***************************************************************
SUB GetMouseInfo (Status%, MCol%, MRow%)
Regs.ax = &H3
CALL Interrupt(&H33, Regs, Regs)
Status% = Regs.bx
MCol% = Regs.cx
MRow% = Regs.dx
END SUB
'***************************************************************
' Turn the Mouse Cursor OFF
'***************************************************************
SUB HideMouse
Regs.ax = &H2
CALL Interrupt(&H33, Regs, Regs)
END SUB
'******************************************************************
' Turn the Mouse Cursor ON
'******************************************************************
SUB ShowMouse
Regs.ax = &H1
CALL Interrupt(&H33, Regs, Regs)
END SUB
