void dialogCreate(){ArxMFCdlg dlg(CWnd::FromHandle(adsw_acadMainWnd()));int nReturnValue=dlg.DoModal();}这个是创建对话框的，如果你按下值为nReturnValue的按钮时摆弄创建一对话框static void initApp(){CAcModuleResourceOverride resOverride;acedRegCmds->addCommand("ACUISAMPLE","arxmfc","arxmfc",ACRX_CMD_MODAL,dialogCreate,NULL,-1,theArxDLL.ModuleResourceInstance());}这段是初始化工程的void unloadApp(){acedRegCmds->removeGroup("ACUISAMPLE");}退出工程switch(msg){case AcRx::kInitAppMsg:acrxDynamicLinker->unlockApplication(pkt);acrxDynamicLinker->registerAppMDIAware(pkt);initApp();break;case AcRx::kUnloadAppMsg:unloadApp();break;case AcRx::kInitDialogMsg:break;}return AcRx::kRetOK;这段是一个SWITCH判断，先初始化APP，如果接受的信息是UnloadApp 当然就执行unloadApp，如果接收到InitDialog的话就不执行操作，最后返回kRetOK的值
