在asp.net中怎么使用com组件？请大侠们指教？

[sdcqsy]

我现在遇到一个这样的问题，我注册了一个dll的组件，做winform程序时可以加裁到工具箱里，但是在做web站点时，却加裁不进去了，请问这是什么原因？有没有解决办法？

你添加Com引用的时候提示什么？

[Lovely_baby]

请引用System.EnterpriseServices.dll   
    
  然后using   System.EnterpriseServices   
    
  从ServiceComponent类派生一个类就可以使用Com+服务了，具体内容请参考：   
  ms-help://MS.VSCC/MS.MSDNVS.2052/cpguide/html/cpconwritingservicedcomponents.htm   
    
    
  示例：   
  BankComponent   服务器

  <assembly:   ApplicationName("BankComponent")>

这个组件应该是FOR WINDOWS的。不支持ASP.NET

[sdcqsy]

我注册了一个dll组件，随便建了一个web站点，在工具箱中加裁该组件的时候，什么提示也没有，仔细查看工具箱之后，里面根本就没有加裁进去

[qingwa008]

你这个com是啥写的？c++?delphi?有啥功能？
regasm tlbExp regsvr32

[sdcqsy]

我现在用的图王（vg.dll),应该是C＋＋写的
