拦截WM_SYSCOMMAND消息。
当wParam等于SC_MINIMIZE时窗口最小化，等于SC_MAXIMIZE时窗口最大化

我的00190> 002F0898 S .WM_MOUSEACTIVATE hwndTopLevel:002F0898 nHittest:HTCAPTION uMsg:WM_LBUTTONDOWN
这条消息是鼠标点击最小化按钮的响应，spy++拦截了所以的消息，包括WM_SYSCOMMAND

WM_WINDOWPOSCHANGING

LPARAM的WINDOWPOS.flags里包含了undocumented SWP_SYTLECHANGED标记，然后可以通过发送WM_GETMINMAXINFO得知具体是将要最大化还是将要最小化

WM_SYSCOMMAND Notification

--------------------------------------------------------------------------------

A window receives this message when the user chooses a command from the Window menu (formerly known as the system or control menu) or when the user chooses the maximize button, minimize button, restore button, or close button.

Syntax


WM_SYSCOMMAND

WPARAM wParam
LPARAM lParam;

Parameters

wParam
Specifies the type of system command requested. This parameter can be one of the following values.
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 lParam parameter identifies the window to activate.
SC_HSCROLL
Scrolls horizontally.
SC_KEYMENU
Retrieves the window menu as a result of a keystroke. For more information, see the Remarks section.
SC_MAXIMIZE
Maximizes the window.
SC_MINIMIZE
Minimizes the window.
SC_MONITORPOWER
Sets the state of the display. This command supports devices that have power-saving features, such as a battery-powered personal computer.
The lParam parameter can have the following values:

1 - the display is going to low power

2 - the display is being shut off

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
Activates the Start menu.
SC_VSCROLL
Scrolls vertically.
lParam
The low-order word specifies the horizontal position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. Otherwise, this parameter is not used.
The high-order word 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 mnemonic.
