Export to 3DS problem

Hey folks,
I am new to this forum and blender. I want to use blender to export objects into a 3DS file to display them in a OpenGL program I wrote. However I have some problems exporting objects. The shapes and forms of the objects are not the issue those work fine, but if I try to attach a material or a texture to a mesh, I can see the result in blender, however not in the 3ds file.
What am I doing wrong?
Thank you in advance for your help
