结果：
1.Server端与Client端中的接口单元代码都是自动生成的，不用手动增加。
2.在Server中增加方法不能手动写（手写的保存时就不见了），必须用Delphi提供的编辑器（相关资料有提到）。
操作步伐：
Server端：
1.File->New->VCL Forms Application - Delphi for Win32->-Sava All。
2.File->New->Other...->Delphi Projects->ActiveX->Automation Object->CoClass Name->D2007Test->OK。
3.在Project1.tlb->选中“ID2007Test”->“New Method”->选中“Paramerers”->点“Add”->增加自己想要的方法。
4.保存Project1.tlb->Project1_TLB中就会有相关的接口方法了。
5.Unit2中编写对应方法的实现体（Variants必须引入）。
6.保存全部
7.生成EXE，在同目录中放一个“RegCom.cmd”文件，里面写上“D2007ComServer.exe -regserver”，双击此文件注册Server。
Client端:
1.File->New->VCL Forms Application - Delphi for Win32->-Sava All。
2.
D7->Project->Import Type Library...->选中“D2007ComServer”->Create Unit。
D2007->Component->Import Component...->选中“Import a Type Library”->Next->选中“D2007ComServer”->Next->Unit Dir Name->Next。
3.Unit1单元就可以编写调用代码了（D2007ComServer_TLB, ActiveX, OleServer必须引入）。
