can I use 3dtexture when rendering to pbuffer

I use pbuffer well under a small win32 application! but when I use pbuffer under MFC and use 3dtexture to draw ,I only produce a white quads. but when ignoring the 3dtexture ,I only use glcolor3f ,it shows me that the pbuffer’s color changed!
so I wonder whether I can use pbuffer as well as 3dtexure!

Call glGetString(GL_VENDOR) or GL_RENDERER and see whether the MFC program got the generic Microsoft renderer.

Also, sprinkle assert(!glGetError()) at the beginning and end of each function, to catch errors early.

I’ve used pbuffers and 3d textures. Can you post some code?
