Hi, i need to Show the drop shadow effect for any window under XP, so i use
the
SetClassLong funtion , so it looks like:
const
CS_DROPSHADOW = $00020000;
...
WndHandle //external window handler.
SetClassLong(WndHandle ,GCL_STYLE, GetClassLong(WndHandle , GCL_STYLE) or
CS_DROPSHADOW) ;
//and then repaint the window
But, when evaluate GetClassLong(WndHandle , GCL_STYLE) always returns 0, and
the effect is not shown.
how can set the shadow effect for any external window?
thanks.
