Top level window or child control?
The shadow on top level windows should be controlled by Windows.

Only the edges of the window
I have an example but the shadow effect is only right and I would like if possible to all four sides.

You can force the class style of the window to have the shadow style but I would not recommend doing it and you cannot control which edges the shadow is on nor the size of it.

FunctionEnd And this is a good example of what not to do. The user might have turned the shadow off for a reason and this code ignores that and forces the shadow on system wide!
Now think about what happens if you run another instance of this program or another program that does the same thing. You will mess up the users settings if you are unlucky with the timing! Or what if another program wants to turn it off? Shadow fight?
You should not use SPI_SET* unless you are some type of control panel applet!
