Hi Fabio,

Thank you very much.

But is very interesting so fuctional setting
SetWindowLong(m.this.hWnd, GWL_EXSTYLE, WS_EX_LAYERED) because in MSDN is:
"If the window has a class style of CS_CLASSDC or CS_OWNDC, do not set the extended window styles WS_EX_COMPOSITED or WS_EX_LAYERED."

And class style of VFP windows is CS_OWNDC.
