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.

// 设置透明窗口
SetWindowLong(m_hWnd, GWL_EXSTYLE, GetWindowLong(m_hWnd, GWL_EXSTYLE)^0x80000); //0x80000 : WS_EX_LAYERED
HINSTANCE hInst = LoadLibrary("User32.DLL"); // 显式加载DLL
if (hInst != NULL)
{
typedef BOOL (WINAPI *MYFUNC)(HWND, COLORREF, BYTE, DWORD);
// 取得SetLayeredWindowAttributes函数指针
MYFUNC pFunc = (MYFUNC)GetProcAddress(hInst, "SetLayeredWindowAttributes");
if (pFunc != NULL)
{
pFunc(m_hWnd, 0, 128, 2); // 2 : LWA_ALPHA
}
FreeLibrary(hInst);
hInst = NULL;
}

add WS_EX_TOPMOST style
use SetLayeredWindowAttributes to set the alpha
