增加监控函数
void WatchDb()
{
if(gpDbr==NULL) gpDbr = new CDbReactor();
AcDbDatabase *pCur=acdbHostApplicationServices()->workingDatabase();
pCur->addReactor(gpDbr);
}
//清除监控函数
void ClearReactors()
{

if(pCur!=NULL) pCur->removeReactor(gpDbr);
delete gpDbr;
gpDbr=NULL;
}
在初始化时增加监控
void InitApplication()
{
// TODO: add your initialization functions
WatchDb();
}
// Unload this application. Unregister all objects
// registered in InitApplication.
//在退出时清除监控
void UnloadApplication()
{
// NOTE: DO NOT edit the following lines.
//{{AFX_ARX_EXIT
//}}AFX_ARX_EXIT
ClearReactors();
//deleteAcRxClass(CPersistentReactor::desc());
// TODO: clean up your application
