能否把概念告知小弟,謝謝!

你是問early binding 與 late binding嗎? 若是請參考 Early binding occurs at compile time rather than run time, so if your code is saved in a compiled state, binding is complete before the code is even run. To return to the phone number analogy, early binding is similar to "speed dialling"—having a phone number in memory rather than having to look it up each time you wish to dial it. Late binding occurs at run time and is much slower than early binding. In late-bound Automation code, Visual Basic must look up an object and its methods and properties each time it executes a line of code that includes that object. To verify that the object and its methods and properties are specified correctly, Visual Basic must check with the operating system and with the application that supplied the object. You can think of late binding as similar to having to look up a phone number in the phone book each time you want to dial the number 原文出處 http://www.dpinfo.com.tw/taiwan/community/1218techtalkQ&A.htm
