      我们在编写程序的过程中，时常有一些比较好的控件，想用到自己的程序中，那么就首先要知道如何来注册OCX控件，下面以Formula控件为例进行说明： 
  在目标机器上注册FormulaOne组件

  在中实现注册，代码如下：

1)在localexternalfunction中定义函数:

   FunctionlongDllRegisterServer()Library"vcf15.OCX"

2)在FormulaOne控件的Constructor事件中增加如下代码：

   longll_rc

   ll_rc=DllRegisterServer()

   ifll_rc＞=0then

  super::EventConstructor()

endif
