2226 * new attribute or extra memory value. If positive, the _offset_
2227 * parameter is the byte-addressed location in the window's extra
2228 * memory to set. If negative, _offset_ specifies the window
2229 * attribute to set, and should be one of the following values:
2231 * GWL_EXSTYLE The window's extended window style
2233 * GWL_STYLE The window's window style.
2235 * GWLP_WNDPROC Pointer to the window's window procedure.
2237 * GWLP_HINSTANCE The window's pplication instance handle.
2239 * GWLP_ID The window's identifier.
2241 * GWLP_USERDATA The window's user-specified data.
2243 * If the window is a dialog box, the _offset_ parameter can be one of
2244 * the following values:
2246 * DWLP_DLGPROC The address of the window's dialog box procedure.
2248 * DWLP_MSGRESULT The return value of a message
2249 * that the dialog box procedure processed.
2251 * DWLP_USER Application specific information.
2255 * If successful, returns the previous value located at _offset_. Otherwise,
2260 * Extra memory for a window class is specified by a nonzero cbWndExtra
2261 * parameter of the WNDCLASS structure passed to RegisterClass() at the
2262 * time of class creation.
2264 * Using GWL_WNDPROC to set a new window procedure effectively creates
2265 * a window subclass. Use CallWindowProc() in the new windows procedure
2266 * to pass messages to the superclass's window procedure.
2268 * The user data is reserved for use by the application which created
2271 * Do not use GWL_STYLE to change the window's WS_DISABLED style;
2272 * instead, call the EnableWindow() function to change the window's
2275 * Do not use GWL_HWNDPARENT to reset the window's parent, use
2276 * SetParent() instead.
2279 * When offset is GWL_STYLE and the calling app's ver is 4.0,
2280 * it sends WM_STYLECHANGING before changing the settings
