I have a little problem. I''d like to draw a transparent window, with only it''s opengl content that is visible. And i''d like to know if it is possible to keep the blending of the opengl objets !! I search on the web, there is the UpdateLayeredWindow function that can draw a transparent window, but i can''t find how to make the opengl drawing visible, and with the blending of the objects keept... (BTW, I''m learnning opengl from your site (lesson 1-13 for now)...thanks a lot).

I came across a tutorial that may be useful. It involves windows "skinning", which creates irregular windows shapes. I don''t know about the blending though. Check it out at http://www.flipcode.com/articles/article_win32skins.shtml

Thank you, i will look at it !

If i can do what i want, i will post a tutorial !

I see that tutorial. It''s a good one on irregular windows.
I hope i will find how to render opengl in a bitmap. Maybe there''s a simple solution... (But there must be something, and i will find it !!
