Hi,
Recently I discovered the beauty of the optical mouse as an incremental position encoder.
An optical mouse usually contains one component in which a camera is linked to an image processor linked to an USB interface. The resolution depends on the camera resolution. On the internet it is easy to find back the datasheets of this type of components describing also how to read/write with them.
My problem...

Automatically detect link to picture?
I have a simple HTML page(not on server, but on PC) and it contains links to pictures.
If I use a memory USB to store the page and I insert the memory USB into another PC I need to change the path so the webpage can still find the link to the picture.
Is it possible to find the link automatically with JavaScript? How?
Thank you in advance! -

printer handle invalid
I have a customer with an hp 2210 all-in-one USB connection, running in Windows XP Pro, that worked fine for several months. I found the printer was no longer recognized and, after attempting to uninstall/reinstall the print driver software, I get a message that "the printer handle is invalid". What does this mean (these error messages never tell you how to fix them!)? The machine tells me the handle is invalid.... any one else have this...
