CWnd::SetWindowPos
BOOL SetWindowPos( const CWnd* pWndInsertAfter, int x, int y, int cx, int cy, UINT nFlags );
Return Value
Nonzero if the function is successful; otherwise 0.
Parameters
pWndInsertAfter
Identifies the CWnd object that will precede this CWnd object in the Z-order. This parameter can be a pointer to a CWnd or a Pointer to one of the following values:
wndBottom Places the window at the bottom of the Z-order. If this CWnd is a topmost window, the window loses its topmost status; the system places the window at the bottom of all other windows.
wndTop Places the window at the top of the Z-order.
wndTopMost Places the window above all nontopmost windows. The window maintains its topmost position even when it is deactivated.
wndNoTopMost Repositions the window to the top of all nontopmost windows (that is, behind all topmost windows). This flag has no effect if the window is already a nontopmost window.
See the “Remarks” section for this function for rules about how this parameter is used.
x
Specifies the new position of the left side of the window.
y
Specifies the new position of the top of the window.
cx
Specifies the new width of the window.
cy
Specifies the new height of the window.
nFlags
Specifies sizing and positioning options. This parameter can be a combination of the following:
SWP_DRAWFRAME Draws a frame (defined when the window was created) around the window.
SWP_FRAMECHANGED 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.
SWP_HIDEWINDOW Hides the window.
SWP_NOACTIVATE 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 the nontopmost group (depending on the setting of the pWndInsertAfter parameter).
SWP_NOCOPYBITS 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.
SWP_NOMOVE Retains current position (ignores the x and y parameters).
SWP_NOOWNERZORDER Does not change the owner window’s position in the Z-order.
SWP_NOREDRAW 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 and scroll bars), and any part of the parent window uncovered as a result of the moved window. When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that must be redrawn.
SWP_NOREPOSITION Same as SWP_NOOWNERZORDER.
SWP_NOSENDCHANGING Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
SWP_NOSIZE Retains current size (ignores the cx and cy parameters).
SWP_NOZORDER Retains current ordering (ignores pWndInsertAfter).
SWP_SHOWWINDOW Displays the window.
Remarks
Call this member function to change the size, position, and Z-order of child, pop-up, and top-level windows.
Windows are ordered on the screen according to their Z-order; the window at the top of the Z-order appears on top of all other windows in the order.
All coordinates for child windows are client coordinates (relative to the upper-left corner of the parent window’s client area).
A window can be moved to the top of the Z-order either by setting the pWndInsertAfter parameter to &wndTopMost and ensuring that the SWP_NOZORDER flag is not set or by setting a window’s Z-order so that it is above any existing topmost windows. When a nontopmost window is made topmost, its owned windows are also made topmost. Its owners are not changed.
A topmost window is no longer topmost if it is repositioned to the bottom (&wndBottom) of the Z-order or after any nontopmost window. When a topmost window is made nontopmost, all of its owners and its owned windows are also made nontopmost windows.
If neither SWP_NOACTIVATE nor SWP_NOZORDER is specified (that is, when the application requests that a window be simultaneously activated and placed in the specified Z-order), the value specified in pWndInsertAfter is used only in the following circumstances:
Neither &wndTopMost nor &wndNoTopMost is specified in the pWndInsertAfter parameter.
This window is not the active window.
An application cannot activate an inactive window without also bringing it to the top of the Z-order. Applications can change the Z-order of an activated window without restrictions.
A nontopmost window may own a topmost window, but not vice versa. Any window (for example, a dialog box) owned by a topmost window is itself made a topmost window to ensure that all owned windows stay above their owner.
With Windows versions 3.1 and later, windows can be moved to the top of the Z-order and locked there by setting their WS_EX_TOPMOST styles. Such a topmost window maintains its topmost position even when deactivated. For example, selecting the WinHelp Always On Top command makes the Help window topmost, and it then remains visible when you return to your application.
To create a topmost window, call SetWindowPos with the pWndInsertAfter parameter equal to &wndTopMost, or set the WS_EX_TOPMOST style when you create the window.
If the Z-order contains any windows with the WS_EX_TOPMOST style, a window moved with the &wndTopMost value is placed at the top of all nontopmost windows, but below any topmost windows. When an application activates an inactive window without the WS_EX_TOPMOST bit, the window is moved above all nontopmost windows but below any topmost windows.
If SetWindowPos is called when the pWndInsertAfter parameter is &wndBottom and CWnd is a topmost window, the window loses its topmost status (WS_EX_TOPMOST is cleared), and the system places the window at the bottom of the Z-order.

固定是什么意思?客户区大小是由cmainframe决定的呀Top

举个例子吧,我让客户区永远是500*400,由cmainframe怎么办

是SDI的吧?这简单!~
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
cs.style&=~(WS_MAXIMIZEBOX|WS_THICKFRAME );
return TRUE;
}

这个方法我不太认同,我需要这两个样式
有没有其他的办法列
我的办法是:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
cs.cx=我要的客户区宽度+12;
cs.cy=我要的客户区高度+73;
return TRUE;
}
我不想用这个办法

搞定:
在oncreate中加上如下代码
CRect rect;
GetWindowRect(&rect);
rect.bottom=rect.top+400;
rect.right=rect.left+500;
this->CalcWindowRect(&rect,CWnd::adjustBorder);
this->MoveWindow(rect.top,rect.left,rect.Width(),rect.Height());

简洁的写法
CRect rect(0,0,500,400);
this->CalcWindowRect(&rect,CWnd::adjustBorder);
this->MoveWindow(rect.top,rect.left,rect.Width(),rect.Height());Top

#%$@%@#...
xpaul(paul)的方法得手动计算主窗口上的非客户区无素的大小。。。而且当用户在显示属性里改变了比如标题栏的高度的话。。。这种方法就失效了。。。
而CalcWindowRect是MFC的CWnd自己计算加上rect中定义的客户区大小后把非客户区加到rect上。。。。。。。
