Remarks

Members

None 0 Indicates any flag.
IgnoreResize 1 Retains the current size (ignores the cx and cy parameters).
IgnoreMove 2 Retains the current position (ignores X and Y parameters).
IgnoreZOrder 4 Retains the current Z order (ignores the hwndInsertAfter parameter).
DontRedraw 8 Does not redraw changes.

If this flag is set, no repainting of any kind occurs.

This applies to the client area, the nonclient area (including the title bar and scroll bars), and any part of the parent window uncovered as a result of the window being moved.

When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing.

DontActivate 16 Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or non-topmost group (depending on the setting of the hWndInsertAfter parameter).
DrawFrame 32 Draws a frame (defined in the window's class description) around the window.
FrameChanged 32 Applies new frame styles set using the SetWindowLong function.

Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed.

If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.

ShowWindow 64 Displays the window.
HideWindow 128 Hides the window.
DontCopyBits 256 Discards the entire contents of the client area.

If this flag is not specified, the valid contents of the client area are saved and copied back into the client area after the window is sized or repositioned.

DontChangeOwnerZOrder 512 Does not change the owner window's position in the Z order.
DontReposition 512 Same as the DontChangeOwnerZOrder flag.
DontSendChangingEvent 1,024 Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
DeferErase 8,192 Prevents generation of the WM_SYNCPAINT message.
AsyncWindowPos 16,384 If the calling thread and the thread that owns the window are attached to different input queues, the system posts the request to the thread that owns the window.

This prevents the calling thread from blocking its execution while other threads process the request.
