100分在线求救，如何获取其它程序的TeitreeView控件里面的内容
100分在线求救，如何获取其它程序的TeitreeView控件里面的内容。
本人主要想读取其它TeitreeView的内容，但是从来没有用过此控件网上根本找不到相关的信息
能获取到此控件的句柄，但是不知道如何发消息获取第一个节点的句柄（而且此控件好象和treeview控件不一样）我用 SendMessage(TeitreeView控件句柄, TVM_GETNEXTITEM, TVGN_ROOT, ByVal 0)取不到节点的句柄。
哪位高手能帮我一下 谢谢了
注：主要是获取某个软件TeitreeView控件上的数据

那个软件我看了，试了一下。拦截不到任何有用的消息。唯一的收获是证实了这个软件中的TeitreeView控件和treeView控件根本不搭边
这样吧，这个软件不是可以备份数据吗，你把备份的数据放到服务器上，然后，其他人从服务器上获取数据后，再导入数据吧
或者，让老板花钱，每台机器都购买一套
