Command List

Retrieves screen resolution, multi-monitor info, dimensions of system objects, and other system properties.

SysGet, OutputVar, Sub-command [, Param3]

Parameters

OutputVar The name of the variable in which to store the result.
Sub-command See list below.
Param3 This parameter is omitted except where noted below.

Sub-commands

MonitorCount: Retrieves the total number of monitors. Unlike SM_CMONITORS mentioned in the table below, MonitorCount includes all monitors, even those not being used as part of the desktop. On Windows 95/NT the count is always 1.

MonitorPrimary: Retrieves the number of the primary monitor, which will be 1 in a single-monitor system. On Windows 95/NT the primary monitor is always 1.

Monitor [, N] : Retrieves the bounding coordinates of monitor number N (if N is omitted, the primary monitor is used). The information is stored in four variables whose names all start with OutputVar. If N is too high or there is a problem retrieving the info, the variables are all made blank. For example:
SysGet, Mon2, Monitor, 2
MsgBox, Left: %Mon2Left% -- Top: %Mon2Top% -- Right: %Mon2Right% -- Bottom %Mon2Bottom%.

Within a function, to create a set of variables that is global instead of local, declare Mon2 as a global variable prior to using this command (the converse is true for assume-global functions).

MonitorWorkArea [, N]: Same as the above except the area is reduced to exclude the area occupied by the taskbar and other registered desktop toolbars.

MonitorName [, N]: The operating system's name for monitor number N (if N is omitted, the primary monitor is used).

(Numeric): Specify for Sub-command one of the numbers from the table below to retrieve the corresponding value. The following example would store the number of mouse buttons in a variable named "MouseButtonCount":
SysGet, MouseButtonCount, 43

Commonly Used

Number Description

68, 69 SM_CXDRAG, SM_CYDRAG: Width and height of a rectangle centered on a drag point to allow for limited movement of the mouse pointer before a drag operation begins. These values are in pixels.
