interdll是什么进程

用PB制作 COM/MTS 相关信息如下
Object:n_interdll COM ClassName:COClass_n_interdll Program ID:interdll
ue_do_clear为调用函数，参数为string 型
pb中Com控件调用程序如下测试成功，VC，VB中如何实现相应功能，请教详细代码
oleobject loo_item
loo_item = create oleobject
li_return = loo_item.connecttonewobject("interdll")

choose case li_return
case 0
case -1
messagebox("警告","控件的属性不能做参数!")
return
case -2
messagebox("警告","没找到相关类!")
return
case -3
messagebox("警告","Object could not be created")
return
case -4
messagebox("警告","Could not connect to object")
return
case -9
messagebox("警告","Other error!")
return
case -15
