*
|

* The _hwnd_ parameter specifies the window. is the handle to a

|

* new attribute or extra memory value. If positive, the _offset_

* attribute to set, and should be one of the following values:
|
|
*
|
|
* GWL_EXSTYLE The window's extended window style

|
|
* 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_DISABLE 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
