Here in our computer lab. in our school when i try to put the www.coffeecup.com the computer says that IEXPLORE.EXE-Application Error and then they ask to Click on OK to terminate the program and Click on Cancel to debug the program and when i push either of the 2 the internet explorer were close. so how can i open coffeecup.com website in our computer lab.?

There aren't any special steps you need to take-- it sounds like your IE is just futzed up, bad. Bring it up to your lab administrator and see if they can fix things up!
