Hello Michel! I'm not sure that it might help you, but in my Sysinfo class I have a method that returns all possible Sysmetrics from Windows. I can't recollect that it have what you need, but you can try it. After all, it's free <g> >they only applied to C/C++. Anyway, I don't think the particular functions >you mentioned are going to be of help. If there are some other API >functions that would be more appropriate, that would be interesting to know >about. If there is any way to use API functions directly from VFP (e.g. >via DECLARE - DLL), that would also be news to me.
