Summary:
PROBLEM ID: WIN9103027
SYMPTOMS
GetSystemMetics(SM_SWAPBUTTON) always returns the state of the
mouse buttons as specified in the WIN.INI file.
CAUSE
When the SwapMouseButton function is used to swap the function of
the left and right mouse buttons, the system metric is not updated.
STATUS
Microsoft has confirmed this to be a problem in Windows version
3.0. This problem was corrected in Windows version 3.1.
More Information:
If it is necessary to keep track of the state of the mouse buttons,
the application must call GetSystemMetrics(SM_SWAPBUTTON) during its
initialization phase. This will return the state of the mouse buttons
as indicated in the WIN.INI file. At each call to SwapMouseButton, the
value of this Boolean variable should be toggled to reflect the
current state of the mouse buttons.
If the change to the state of the mouse buttons is to be permanent,
the WIN.INI file must be updated using the WriteProfileString
function. Please note that the SwapMouseButton function is usually
called only by the Control Panel. Although applications are free to
call the function, the mouse is a shared resource. Reversing the state
of the mouse buttons will affect all applications.
