GDI and GDIplus
-
Hello, Can GDI and GDIplus co-exist in the VC project. I am thinking of mixing use of these libraries. My existing library is using GDI but it seems that GDIplus has some cool functions which I think it would great to incorporate into it also. Possible? Would it crash or lib conflict? thank you.

Hi I haven't used GDI+ but inspecting the GDI+ Graphics class, I see a constructor that takes a HDC, so you should be able to mix the 2. Martin

Yes they can coexist. But the trick is getting the HDC for GDI drawing. You have to first create the Gdiplus::Graphics object that you will do all your drawing on, then call Graphics::GetHDC to get the HDC you need for your GDI calls. If you draw on a HDC with GDI and then try to attach a Graphics object to the same HDC the Graphics constructor will erase all the drawing you have done. Lookup Graphics::GetHDC and Graphics::ReleaseHDC in MSDN for more info.
