Да. SC_MINIMIZE:
A window receives this message when the user chooses a command from the window menu (also known as the System menu or Control menu) or when the user chooses the Maximize button or Minimize button.

WM_SYSCOMMAND
uCmdType = wParam; // type of system command requested
xPos = LOWORD(lParam); // horizontal postion, in screen coordinates
yPos = HIWORD(lParam); // vertical postion, in screen coordinates

Parameters

uCmdType

Specifies the type of system command requested. This can be one of these values:

Value Meaning
SC_CLOSE Closes the window.
SC_CONTEXTHELP Changes the cursor to a question mark with a pointer. If the user then clicks a control in the dialog box, the control receives a WM_HELP message.
SC_DEFAULT Selects the default item; the user double-clicked the window menu.
SC_HOTKEY Activates the window associated with the application-specified hot key. The low-order word of lParam identifies the window to activate.
SC_HSCROLL Scrolls horizontally.
SC_KEYMENU Retrieves the window menu as a result of a keystroke.
SC_MAXIMIZE (or SC_ZOOM) Maximizes the window.
SC_MINIMIZE (or SC_ICON) Minimizes the window.
SC_MONITORPOWER Windows 95 only: Sets the state of the display. This command supports devices that have power-saving features, such as a battery-powered personal computer.
SC_MOUSEMENU Retrieves the window menu as a result of a mouse click.
SC_MOVE Moves the window.
SC_NEXTWINDOW Moves to the next window.
SC_PREVWINDOW Moves to the previous window.
SC_RESTORE Restores the window to its normal position and size.
SC_SCREENSAVE Executes the screen saver application specified in the [boot] section of the SYSTEM.INI file.
SC_SIZE Sizes the window.
SC_TASKLIST Executes or activates Windows Task Manager.
SC_VSCROLL Scrolls vertically.

xPos

Specifies the horizontal position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. Otherwise, the xPos parameter is not used.

yPos

Specifies the vertical position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. This parameter is -1 if the command is chosen using a system accelerator, or zero if using a mnenomic.

Return Values

An application should return zero if it processes this message.
