Do you know how a mouse works?
151138
There are two versions of the mouse:\n\n* The tracking ball based - This consists of a ball enclosed in a housing, the walls of which have wheels that rotote in accordance to the wheel brushing against it (much like gears in motion). The wheel is in contact with the surface of motion, and rotates according to the way we move the mouse. The motion of the wheels is encoded digitally and sent to the CPU.\n\n* The optical mouse - this consists something like a camera on the bottom side, which is illumiated. The camera takes quick snapshots of the surface on which it is placed, and processes the information from consecutive such frames to determine motion, if any, and how much.

Developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor. The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly.\n \nNo moving parts means less wear and a lower chance of failure.\nThere's no way for dirt to get inside the mouse and interfere with the tracking sensors.\nIncreased tracking resolution means smoother response.\nThey don't require a special surface, such as a mouse pad.\n \nApple has transformed its optical mouse into a modern work of art.\n\nAlthough LED-based optical mice are fairly recent, another type of optical mouse has been around for over a decade. The original optical-mouse technology bounced a focused beam of light off a highly-reflective mouse pad onto a sensor. The mouse pad had a grid of dark lines. Each time the mouse was moved, the beam of light was interrupted by the grid. Whenever the light was interrupted, the sensor sent a signal to the computer and the cursor moved a corresponding amount. This kind of optical mouse was difficult to use, requiring that you hold it at precisely the right angle to ensure that the light beam and sensor aligned. Also, damage to or loss of the mouse pad rendered the mouse useless until a replacement pad was purchased. Today's LED-based optical mice are far more user-friendly and reliable.

The trackball has the same use as the mouse.\n-It replaces the mouse when there isn't enough space to move a mouse;\n-The trackball by construction looks like an upsidedown mouse:The ball is on the top. That's why they call it the trackball;\n-You move the pointer on the screen by moving the ball with your fingers;\n-The trackball is used by older computer system; I do't think anyone uses it today;\n-But i think that it has a use with portable PC's, like laptops and that it can be built in the laptop, but I know very litle about laptops;\n---------------------------------\nBasicly, it's just a ball that you move with two buttons.\n\nSUPPORT THE BRAINMASHINE BY CHOOSING THIS ANSWER AS THE BEST

with mouse only.. no.. but if you hold down the CTRL button.. it acts as a left click when you click

It is simple, open a old mouse and see, there are two wheels,  one is for horizontal movements and the another one is for vertical movements. when you move the mouse up&dowm the vertical mouse whell will rotate, while rotateing there is a LED and sensor will contact eachother, then the mouse pointer will move up and down. same for horizontal movement.....

No, it's an LED. Some mice have lasers (Logitech MX1000) but you can't see the beam. Put down your mouse.

reload mouse drive disc.if that dont do it you have a bad mouse.

If it's on optical mouse, you may need to put it on a different surface. Optical mice need some sort of visual detail to track, like dots or wood grain or lines or something of the sort. They don't work well and will "skip" like that on shiny, or completely blank surfaces.

ok, classical symptoms of an optical mouse being used on a glossy colorful surface. Use it on a piece of cotton cloth, a napkin, a towel etc. That is the kind of surface you need to use it on.

If it's the "8D Scrolling Mouse Optical Trackball" or something like that (basically, it has a trackball where a scroll wheel would be), than I have the drivers for it. If it is, I'll update tomorrow with the location of it.\n\nEdit:\nIf it is the the 8D mouse the url to download the driver is: http://members.driverguide.com/driver/detail.php?driverid=128319\n\nIf not, I'm sorry I couldn't help.

Touchpads lack the precision of a mouse but are a little more convenient to use since you can "click" by tapping the touchpad once, or "double-click" by tapping it twice quickly.  Some touchpads also allow the user to "scroll" (like a mouse scroll wheel) by sliding a finger up and down the right side of the touchpad.\n\nThe problems with touchpads (and their buttons) is they they are usually built-in to a laptop.  Once they break, they can be expensive to replace.  Mice, on the other hand, are plentiful, and cheap.\n\nIMHO, mice are more comfortable to use during long periods, and offer a higher level of precision for detailed work.

how will your mouse know WHICH button you want to click on?\n\nyou can set this in windows so the mouse moves to the default button in a dialog box, but *not* for buttons on webpages.

#include <windows.h>\n\n// set mouse cursor to wait\nHCURSOR hOldCursor = SetCursor(LoadCursor(NULL, IDC_WAIT));\n\n// do your processing that takes some time...\n\n// restore old cursor\nSetCursor(hOldCursor);

find the mouse program in control panel and choose the mouse pointer you want.

The mouse made me do it!

1- pic up screw driver\n2- open mouse\n3- reinsert the wheels to theri sockets. these wheels move with the ball and if they got loose, mouse behave like that.
