我也把自己的research update一下。
现在的一个问题就是PPC上还是比较模糊，我准备先写个方便检测的tool。
下面是我的操作的log，蓝色字体是原版的工具log，红色字体是自己的一些分析,后面附了一些代码定义，方便理解。
删除一条记录：
Id: 128, Provider: MS.WinCE.StockPor2, Interface: IReplNotify, Function: OnItemNotify(), Params: (uCode: 3, lpszProgId: MS.WinCE.StockPor2, lpszName: StockPor, hItem: 0x2334a98, ulFlags: 0), Time: 0.0000383, Return: 0
删除纪录后，立刻就调用这个函数了。同样的问题，谁来告诉ActiveSync Manager，我删出记录了？uCode: 3 可以代码里是#define RNC_DELETED 3 lpszProgId和lpszName应该是注册表里读出来的， hItem的类型是HREPLITEM，其中包含着uid，应该是唯一的 x2334a98这个数字下面都用到了就可以代表这个Item, ulFlags:始终是0没意义
Id: 128, Provider: MS.WinCE.StockPor2, Interface: IReplStore, Function: CompareItem(), Params: (hItem1: 0x23348e0, hItem2: 0x2334a98), Time: 0.0001229, Return: -1
Id: 129, Provider: MS.WinCE.StockPor2, Interface: IReplStore, Function: CompareItem(), Params: (hItem1: 0x2334960, hItem2: 0x2334a98), Time: 0.0001461, Return: -1
Id: 131, Provider: MS.WinCE.StockPor2, Interface: IReplStore, Function: CompareItem(), Params: (hItem1: 0x23349a0, hItem2: 0x2334a98), Time: 0.0001528, Return: -1
Id: 132, Provider: MS.WinCE.StockPor2, Interface: IReplStore, Function: CompareItem(), Params: (hItem1: 0x2334760, hItem2: 0x2334a98), Time: 0.0001400, Return: 0
可以看到这里在比较，hItem2: 0x2334a98就是我删除的Item，hItem1我推测是device端的HREPLITEM，因为后面的ReportStatus把0x2334760传给了PPC,前面几次都返回-1，没找到，最后一次，返回0，找到相等的 Item(uid相等)
Id: 133, Provider: MS.WinCE.StockPor2, Interface: IReplStore, Function: FreeObject(), Params: (hObject: 0x2334a98), Time: 0.0001726, Return: 0

对于这里进行这么多次的ObjectToBytes，我还没想到为什么。

uStatus: 7,代码里是RSC_REMOTE_SYNC

Folder没有发生变化

从上面的ReportStatus中的uStatus代码可以猜出Activesync manager正在把删除这个事情告诉ppc，并进行了一些操作

又来了好多的ObjectToBytes
Over!

我觉得这里的比较是在看新创建的与已有的比较，当然不可能有一样的，所有都返回-1，但数据库里只有9条记录，我不知道为什么比较了10次。
