The GetSystemMetrics function retrieves various system metrics (widths and heights of display elements) and system configuration settings. All dimensions retrieved by GetSystemMetrics are in pixels.
C# Signature:[DllImport("user32.dll")]
static extern int GetSystemMetrics(SystemMetric smIndex);
User-Defined Types:
http://pinvoke.net/default.aspx/Enums.SystemMetric
Parameters:
smIndex
in System metric or configuration setting to retrieve. This parameter can be one of the following values. Note that all SM_CX* values are widths and all SM_CY* values are heights. Also note that all settings designed to return Boolean data represent TRUE as any nonzero value, and FALSE as a zero value.
Notes:
System metrics may vary from display to display.
GetSystemMetrics(SM_CMONITORS) counts only display monitors. This is different from EnumDisplayMonitors, which enumerates display monitors and also non-display pseudo-monitors.
The SM_ARRANGE setting specifies how the system arranges minimized windows, and consists of a starting position and a direction. The starting position can be one of the following values.
Value Meaning
ARW_BOTTOMLEFT Start at the lower-left corner of the screen (default position).
ARW_BOTTOMRIGHT Start at the lower-right corner of the screen. Equivalent to ARW_STARTRIGHT.
ARW_HIDE Hide minimized windows by moving them off the visible area of the screen.
ARW_TOPLEFT Start at the upper-left corner of the screen. Equivalent to ARV_STARTTOP.
