...kind of.
Basically, when you're shooting with flash, it's as if you're exposing the picture twice. Once for the bit the flash hits, once for everything else in the frame. The flash part of the exposure is dictated by the flash power, the aperture, and the ISO--shutter speed doesn't really enter into it as long as you're slower than the flash sync speed for your camera.
So there are two possibilities: 1. You take the picture with a fast shutter speed. The flash lights up as much as it can, but you get that standard "Brightly lit person in a tunnel" look common to P&S cameras and onboard flash 2. You take the picture with a slow shutter speed. The main subject gets burned in significantly, by the flash, but there's still a little bit of exposure after the flash that blurs the edges a bit, especially if they move at all. Background burns in more slowly thanks to available light.
Attached is a pic taken with a fairly slow 1/13th shutter and crappy on-camera flash to show you what it looks like when you do that.
