	Hello, I am developping an application under DirectX 9. To render a page of my PDF file : 1/ I create an offscreen surface using CreateOffscreenPlainSurface method 2/ I get the device context of this surface with GetDC method 3/ I render using DARenderPageToDC on the device context 4/ I copy the surface onto the backbuffer DARenderPageToDC tells me everything OK Is this process OK because nothing is rendered on the screen ? Many Thanks !

	Hi! Did you use non-DA-functions together with DA-functions? This doesn't work. Cheers, Ingo

	Hi, What do you mean by using DA and non DA functions ? I only use DARenderPageToDC. Do you mean I must not use this function and should use RenderPageToDC instead ? Is there any example in rendering under DirectX ? Many Thanks !

	Sorry, I don't use DARenderPageToDC but RenderPagePageToDC. I only use the DA function : DAFindPage to look for the page reference

	Hi! There are DA-functions and non-DA-functions. If you're using both kinds of functions in one instance then the results won't be correct. So it's not possible to use LoadFromFile... and later in the code DARender... If you're using DARender... then you have to use DAOpenFile... Cheers, Ingo

	OK Many thanks. Is there any DirctX example ? If not, am I right with GetDC ?

	Hi Marc! There's no DirectX-sample but about using RenderPageToDC you'll find a lot with the search-function (the advanced one, above): http://www.quickpdf.org/forum/quickpdf-render-to-device-context_topic1197_post5551.html?KW=RenderPageToDC#5551 http://www.quickpdf.org/forum/newbe-question_topic1134_post5265.html?KW=RenderPageToDC#5265 http://www.quickpdf.org/forum/pdf-viewer-in-vb6_topic1114_post5180.html?KW=RenderPageToDC#5180 http://www.quickpdf.org/forum/renderpagetodc-example-needed_topic1036_post4882.html?KW=RenderPageToDC#4882 Cheers, Ingo
