There are two places you can find Solid Edge examples.
The first is on the Solid Edge Installation disk. A folder named SDK\Advanced has this content. If your system manager has already installed these files, you will find thiem under the SDK folider in the location where Solid Edge is installed on your computer.
The second place you gent get exmaples is from the Microsoft CodePlex site. Community members are encouraged to add thier own examples as well.
