I have tried the code from here
to make a transparent window, this works very fine !
except in this case : I have a control which uses this stuff of code but my control calls the :raw method regularly (when refreshing) ; therefore the transparency code is called each time the draw method is excecuted and each time, the transparency becomes less until it's completely un-transparent (like a full rectangle is displayed) !
must I stop the transparent effect ? and how ? I have tried the .SetNonTransparent() at the end of :raw to reset to original state without success !
any help is appreciated !
