wndclass.style = CS_DBLCLKS;
CS_BYTEALIGNCLIENT Aligns the
window's client area on the byte boundary (in the x direction). This style affects the
width of the window and its horizontal position on the display.
CS_BYTEALIGNWINDOW Aligns a window on a byte
boundary (in the x direction). This style affects the width of the window and its
horizontal position on the display.
CS_CLASSDC Allocates one device context to be shared
by all windows in the class. Because window classes are process specific, it is possible
for multiple threads of an application to create a window of the same class. It is also
possible for the threads to attempt to use the device context simultaneously. When this
happens, the system allows only one thread to successfully finish its drawing operation.
For more information, see Device Contexts.
CS_DBLCLKS Sends double-click messages to the window procedure when
the user double-clicks the mouse while the cursor is within a window belonging to the
class.
CS_GLOBALCLASS Allows an application to create a
window of the class regardless of the value of the hInstance parameter passed to the
CreateWindow or CreateWindowEx function. If you do not specify this style, the hInstance
parameter passed to the CreateWindow (or CreateWindowEx) function must be the same as the
hInstance parameter passed to the RegisterClass function. You can create a global class by
creating the window class in a dynamic-link library (.dll) and listing the name of the
.dll in the registry under the following keys: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Windows \AppInit_DLLs.
Whenever a process starts, the system loads the specified .dlls in the context of the
newly started process before calling the entry-point function in that process. The .dll
must register the class during its initialization procedure and must specify the
CS_GLOBALCLASS style.
CS_HREDRAW Redraws the
entire window if a movement or size adjustment changes the
width of the client area.
CS_NOCLOSE Disables Close on the window menu.
CS_OWNDC Allocates a unique device context for each
window in the class.
CS_PARENTDC Sets the clipping region of the child
window to that of the parent window so that the child can draw on the parent. A window
with the CS_PARENTDC style bit receives a regular device context from the system's cache
of device contexts. It does not give the child the parent's device context or device
context settings. Specifying CS_PARENTDC enhances an application's performance. For more
information, see Device Contexts.
CS_SAVEBITS Saves, as a bitmap, the portion of the
screen image obscured by a window. The system uses the saved bitmap to re-create the
screen image when the window is removed. The system displays the bitmap at its original
location and does not send WM_PAINT messages to windows obscured by the window if the
memory used by the bitmap has not been discarded and if other screen actions have not
invalidated the stored image. This style is useful for small windows (for example, menus
or dialog boxes) that are displayed briefly and then removed before other screen activity
takes place. This style increases the time required to display the window, because the
system must first allocate memory to store the bitmap.
CS_VREDRAW Redraws the
entire window if a movement or size adjustment changes the
height of the client area.

ウィンドウズの種類を決めるには．．．
WS_BORDER Creates a window that has a thin-line
border.
WS_CAPTION Creates a window that has a title bar
(includes the WS_BORDER style).
WS_CHILD (or WS_CHILDWINDOW)
Creates a child window. This style cannot be used with the WS_POPUP style.
WS_CLIPCHILDREN Excludes the area occupied by child
windows when drawing occurs within the parent window. This style is used when creating the
parent window.
WS_CLIPSIBLINGS Clips child windows relative to each
other; that is, when a particular child window receives a WM_PAINT message, the
WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the
child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap,
it is possible, when drawing within the client area of a child window, to draw within the
client area of a neighboring child window.
WS_DISABLED Creates a window that is initially
disabled. A disabled window cannot receive input from the user. To change this after a
window has been created, use EnableWindow.
WS_DLGFRAME Creates a window that has a border of a
style typically used with dialog boxes. A window with this style cannot have a title bar.
WS_GROUP Specifies the first control of a group of
controls. The group consists of this first control and all controls defined after it, up
to the next control with the WS_GROUP style. The first control in each group usually has
the WS_TABSTOP style so that the user can move from group to group. The user can
subsequently change the keyboard focus from one control in the group to the next control
in the group by using the direction keys. You can turn this style on and off to change
dialog box navigation. To change this style after a window has been created, use SetWindowLong.
WS_HSCROLL Creates a window that has a horizontal scroll bar.
WS_ICONIC (or WS_MINIMIZE) Creates
a window that is initially minimized. Same as the WS_MINIMIZE style.
WS_MAXIMIZE Creates a window that is initially
maximized.
WS_MAXIMIZEBOX Creates a window that has a Maximize
button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must
also be specified.
WS_MINIMIZEBOX Creates a window that has a Minimize
button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must
also be specified.
WS_OVERLAPPED (or WS_TILED) Creates
an overlapped window. An overlapped window has a title bar and a border. Same as the
WS_TILED style.
WS_OVERLAPPEDWINDOW
(or WS_TILEDWINDOW) Creates an overlapped window with the WS_OVERLAPPED, WS_CAPTION, WS_SYSMENU, WS_THICKFRAME,
WS_MINIMIZEBOX, and WS_MAXIMIZEBOX
styles. Same as the WS_TILEDWINDOW style.
WS_POPUP Creates a pop-up window. This style cannot
be used with the WS_CHILD style.
WS_POPUPWINDOW Creates a pop-up window with
WS_BORDER, WS_POPUP, and WS_SYSMENU styles. The WS_CAPTION and WS_POPUPWINDOW styles must
be combined to make the window menu visible.
WS_SIZEBOX (or WS_THICKFRAME)
Creates a window that has a sizing border. Same as the WS_THICKFRAME style.
WS_SYSMENU Creates a window that has a window-menu
on its title bar. The WS_CAPTION style must also be specified.
WS_TABSTOP Specifies a control that can receive the
keyboard focus when the user presses the TAB key. Pressing the TAB key changes the
keyboard focus to the next control with the WS_TABSTOP style. You can turn this style on
and off to change dialog box navigation. To change this style after a window has been
created, use SetWindowLong.
WS_VISIBLE Creates a window that is initially
visible. This style can be turned on and off by using ShowWindow
or SetWindowPos.
WS_VSCROLL Creates a window that has a vertical scroll bar.

- SW_FORCEMINIMIZE（どうあっても最小にする） Windows NT 5.0 and later: Minimizes
a window, even if the thread that owns the window is hung. This flag
should only be used when minimizing windows from a different thread.
- SW_HIDE（隠れていて表示されない）
Hides the window and activates another
window.
- SW_MAXIMIZE（最大化する） Maximizes
the specified window.
- SW_MINIMIZE（最小化する） Minimizes
the specified window and activates the next top-level window in the Z order.
- SW_RESTORE（隠れているのもは視覚化し、最初の状態の大きさにする）
Activates and displays the window. If the window is minimized or maximized, the system
restores it to its original size and position.
An application should specify this flag when restoring a
minimized window.
- SW_SHOW（（隠れているのもは視覚化し、現在の状態で表示する）
Activates the window and displays it in its
current size and position.
- SW_SHOWDEFAULT（nCmdShowに従う） Sets the show state based on the SW_flag specified in the STARTUPINFO structure
passed to the CreateProcess function by the program that started the application.

in its most recent size and position. The
active window remains active.
- SW_SHOWNORMAL（隠れているのもは視覚化し、最初の状態の大きさにする）
