thanks a lot... I'll look into it...

Right now, I'm managing resizing by hand by looking where the cursor is and
displaying the good cursor at the right time and sizing when I have to size
by modifying Left, Top, Width and Height... I have a bug tought when I'm
sizing from Left or Top, The window start to move around when it's width and
height = 0. That was the only way I found I could do it with borderless
windows... for now, I will try to use the "more standard way" you explain
here and fill the blanks with what is explained on the site...

For the
3D Border I must get rid of it because I use the TransparencyKey of the .Net
Form, so even if my background it completely transparent, the border still
show because I don't have to use region by now... But the example on the
site already get rid of the border even if the window is sizable.
if you have better examples for this exact same purpose, would you be so
kind as to post them here or on my e-mail please? (just get rid of the
NoSpAm at the beginning, the @NoSpAm.com at the end and decode...)

and
please indicate in the subjet you are from the newsgroups because your
message will probably end up in my junk folder, so I must be able to
recognize you...
thanks again...
