* SetWindowLongW (USER32.@) Set window attribute
*
* SetWindowLong() alters one of a window's attributes or sets a 32-bit (long)
* value in a window's extra memory.
*
* The _hwnd_ parameter specifies the window. is the handle to a
* window that has extra memory. The _newval_ parameter contains the
* new attribute or extra memory value. If positive, the _offset_
* parameter is the byte-addressed location in the window's extra
* memory to set. If negative, _offset_ specifies the window
* attribute to set, and should be one of the following values:
*
* GWL_EXSTYLE The window's extended window style
*
* GWL_STYLE The window's window style.
*
* GWLP_WNDPROC Pointer to the window's window procedure.
*
* GWLP_HINSTANCE The window's pplication instance handle.
*
* GWLP_ID The window's identifier.
*
* GWLP_USERDATA The window's user-specified data.
*
* If the window is a dialog box, the _offset_ parameter can be one of
* the following values:
*
* DWLP_DLGPROC The address of the window's dialog box procedure.
*
* DWLP_MSGRESULT The return value of a message
* that the dialog box procedure processed.
*
* DWLP_USER Application specific information.
*
* RETURNS
*
* If successful, returns the previous value located at _offset_. Otherwise,
* returns 0.
*
* NOTES
*
* Extra memory for a window class is specified by a nonzero cbWndExtra
* parameter of the WNDCLASS structure passed to RegisterClass() at the
* time of class creation.
*
* Using GWL_WNDPROC to set a new window procedure effectively creates
* a window subclass. Use CallWindowProc() in the new windows procedure
* to pass messages to the superclass's window procedure.
*
* The user data is reserved for use by the application which created
* the window.
*
* Do not use GWL_STYLE to change the window's WS_DISABLED style;
* instead, call the EnableWindow() function to change the window's
* disabled state.
*
* Do not use GWL_HWNDPARENT to reset the window's parent, use
* SetParent() instead.
*
* Win95:
* When offset is GWL_STYLE and the calling app's ver is 4.0,
* it sends WM_STYLECHANGING before changing the settings
* and WM_STYLECHANGED afterwards.
* App ver 4.0 can't use SetWindowLong to change WS_EX_TOPMOST.
