I'm using build 210 and I've got that method.

This snippet is clearly wrong, because (a) win32gui is not capitalized, 
(b) window handles are not floating point numbers, and (c) the RGB 
function requires three arguments:
    win32api.RGB(255,255,255)

What version of PyWin32 are you running?  Mine doesn't include 
win32gui.SetLayeredWindowAttributes at all.

Do you mean win32gui.FindWindow?  That calls the API directly, and the 
API doesn't handle wildcards, unless Mark added this in some new 
release.  In addition, Henry is right; you can only call 
SetLayeredWindowAttributes on a window with the WS_EX_LAYERED style.  
You can set that style on a window by using SetWindowLong, although 
there's no telling how the application that owns the window will
respond.
