Is it possible to make some special effects like, reflection, water effect, or some thing like shaders in DBC?

P3 CPU 500 Mhz, 128 MB RAM, 16 MB VRAM, WinXP.
Almost the best configuration for game development.

Nope...you have to use dbpro for these.

I am sure it could be done, but it would be very complicated, resource intensive, and impractical for anything but a still image.

Not sure, but just my assumption.

Ever notice how in Microsoft word, the word "microsoft" is auto corrected to be "Microsoft" but "macintosh" just gets the dumb red underline?

I think you could create a perfect "Mirror" reflection in DBC - what you'd have to do is finish setting the scene, temporarily reposition your camera to where the mirror is, grab an image of what the camera/mirror was seeing and then use that image as the texture for your "Mirror" object.

I'm sure I've seen this mentioned before (maybe with an example?) but I can't find the link.

It was talking about a way of creating security cameras, so you could view other areas of your 3d world on little television screens - the principle here's the same.

If I admit that I'm lying, am I telling the truth?

Higher level direct x functionality is out of reach for DBC for the most part (of course if you're a pro at the direct x sdk and c/c++ you could work something out). Many, if not most, effects can be "faked" in DBC with clever use of lighting, textures, ghosting, and objects.

Check out these examples:

The mirror thing is possible - if you go through the DBC challenges you'll find an example I posted - but for any practical use in a game, switching the camera back and forth while capturing an image ends up jittery and/or kills the frame rate. Part of the problem is the get image command. It's just not fast enough. There's a few tricks to get it to look ok... but it's still not great. It's something to try and play with though.

Enjoy your day.

Doesn't dbc have the "set camera to image" command or whatever it's called. If you have a second camera where your mirror mesh is then the command let's you set the output of the camera to the texture of the mirror.
