GetSystemMetrics functions in the Win32 API

1.
Sm_arrange: Used to illustrate how the system arranges minimized windows, depending on the system data of the monitor may be different. It contains a starting position and direction. I haven't seen such a code about how to use it in a program.

The starting position can be one of the following values:
Arw_bottomleft: Start the screen in the lower left corner (the default value).
Arw_bottomright: Start at the bottom right corner of the screen (equivalent to arw_startright).
Arw_hide: Hides and minimizes the window in the visible area of the screen.
Arw_topleft: From the upper left corner of the screen (equivalent to arw_starttop).
Arw_topright: Start on the screen in the upper right corner (equivalent to Arw_starttop | Arw_startright).

The direction of the arrangement can be one of the following values:
Arw_down: vertically arranged from top to bottom.
ARW_UP: vertically arranged from bottom to top.
Arw_left: Arranges horizontally from left to right.
Arw_right: Arranges horizontally from right to left.

2.
Sm_cleanboot returns the way the system is started.
0: Normal start.
1: Safe mode starts.
2: Network security mode is started.
code example:
Nboot = GetSystemMetrics (sm_cleanboot);
Switch (nboot)
{
Case 0:
MessageBox (Null,text ("Normal boot System!"), TEXT ("hint"), MB_OK);
Break
Case 1:
MessageBox (Null,text ("Safe Mode boot System!"), TEXT ("hint"), MB_OK);
Break
Case 2:
MessageBox (Null,text ("Network Safe Mode Boot system!"), TEXT ("hint"), MB_OK);
Break
}

3,
Sm_cmousebuttons: The return value is the number of mouse keys supported by the system and returns 0 without the mouse installed in the system.
code:
nmousebutton = GetSystemMetrics (SM_ Cmousebuttons);
  sprintf (Szbuffer, "%d", Nmousebutton);
  messagebox (Null,szbuffer,text ("system supports mouse Keys"), MB_OK | mb_iconinformation);

4.
Sm_cxborder, Sm_cyborder: Returns the width and height of the Windows border, in pixels, equivalent to Sm_cxedge if it is in 3D form.
Code:
int cxborder = 0;
int cyborder = 0;

Cxborder =getsystemmetrics (Sm_cxborder);
Cyborder =getsystemmetrics (Sm_cyborder);

sprintf (Szbuffer, "the window's border length:%d, Width:%d", cxborder,cyborder);
MessageBox (Null,szbuffer,text ("Border Information"), MB_OK);

5.
Sm_cxcursor, Sm_cycursor: Returns the width and height of the standard cursor in pixels.
Code:
int cxcursor = 0;
int cycursor = 0;

Cxcursor = GetSystemMetrics (sm_cxcursor);
Cycursor =getsystemmetrics (sm_cycursor);

sprintf (szbuffer, "system standard cursor width is:%d, height is:%d", cxcursor,cycursor);
MessageBox (Null,szbuffer,text ("cursor Information"), MB_OK);

6,
Sm_cxdlgframe, Sm_cydlgframe: equivalent to Sm_cxfixedframe, Sm_cyfixedframe.
sm_cxfixedframe, Sm_cyfixedframe: The border thickness around a window (usually a dialog box) that has a caption but cannot resize.
//the thickness here and the length and width of the top border are the parts of the window respectively
// The values obtained on my system are Cxborder = Cyborder = 1;cxframe = Cyframe = 3;
// > You want to know the pros.

   Cxframe =getsystemmetrics (sm_cxdlgframe);
   cyframe =getsystemmetrics (sm_cydlgframe);

sprintf (Szbuffer, "the thickness of the border is:%d, height is:%d", cxframe,cyframe);
MessageBox (Null,szbuffer,text ("Border Information"), MB_OK);

7.
SM_CXDOUBLECLK, SMCYDOUBLECLK: Double-click a valid rectangular area in pixel values.
Code:
int cxdoublerect = 0;
int cydoublerect = 0;

Cxdoublerect = GetSystemMetrics (SM_CXDOUBLECLK);
Cydoublerect =getsystemmetrics (SM_CYDOUBLECLK);

sprintf (Szbuffer, "effective area width:%d, H:%d", cydoublerect,cydoublerect);
MessageBox (Null,szbuffer,text ("Active Area Information"), MB_OK);
The result is Cxdoublerect = 4,cydoublerect = 4;

8.
Sm_cxframe, Sm_cyframe: equivalent to Sm_cxsizeframe, sm_cysizeframe
Sm_cxsizeframe, Sm_cysizeframe: The thickness around the window border that can be resized.

9.
Sm_cxfullscreen, Sm_cyfullscreen: The width and height of the window area of the full-screen window.

10.
Sm_cxhscroll, Sm_cyhscroll: The width of the horizontal scroll bar and the height of the arrows on the horizontal scrollbar.
Code:

int cxhscroll = 0;
int cyhscroll = 0;

Cxhscroll = GetSystemMetrics (Sm_cxhscroll);
Cyhscroll =getsystemmetrics (Sm_cyhscroll);

sprintf (szbuffer, "Horizontal scrollbar Height:%d, arrowhead height:%d", cxhscroll,cyhscroll);
MessageBox (Null,szbuffer,text ("TIP"), MB_OK);

11.
Sm_cxhthumb: Width of the slider on the horizontal scroll bar

12.
Sm_cxicon, Sm_cyicon: The width and height of the system default icon (typically 32x32).

13.

14.
Sm_cxmaximized, sm_cymaximized: The default size of the maximized window at the top level.
