Manko, I've followed your enlightening advice, but I've got nowhere.

BTW the EnableWindow quotation was mine, so probably I can't figure out either what I'm reading.

It seems to me that my API reference indicates in EnableWindow the only way to *change* the state; maybe is there something different in yours? "CreateWindow" (mentioned in my API-reference in that context) can only *create* a disabled control, not change it; in fact, my question was: "in which way, other than using WM_ENABLE, could you *change* the state of a control?"

So, I probably have to admit my stupidity rather than my ignorance. Since you're so kind as to work for me, could you explain, please, what I should read in my (or in your) API-reference?

Thanks in advance for your consultancy
