VC++在程序中用代码注册和卸载ocx控件，在软件开发过程中，我们经常会用一些免费或收费的OCX控件，这样可加快开发进度，使用OXC控件之前需要注册，使用完成后为了减少资源浪费我们还需要卸载这些控件，可以用Delphi或VC的工具来实现，但如果用程序自身来实现，会更方便，该如何实现呢？

　　一般情况下，控件的OCX文件中已包含有DLLRegisterServer和DLLUnregisterServer函数，我们只需调用它们便可实现OCX控件的注册与卸载。-VC++ program using the code registration and unloading ocx controls in the software development process, we often use some free or OCX controls, which can speed up the development progress, need to register before using the OXC control after use to complete in order to reduce the waste of resources we also need to uninstall these controls, you can use Delphi or VC tool to achieve, but if the program itself to achieve, would be more convenient, how to achieve it?

Under normal circumstances, OCX file already contains the control DLLRegisterServer and DLLUnregisterServer function, we can simply call them achieve registration and unloading OCX controls.
