online help里面"Windows DDE"Channel 的帮助信息很奇怪啊~
在WinCC V6.0 sp2里面,搜索DDE,发现这样的信息
Contents
The channel was used in earlier WinCC for linking to application via the Windows DDE port and is only included for compatibility to earlier WinCC versions.New links must be made via the "OPC" channel
这样子写是什么意思呢?使用DDE仍然可以与Excel交换数据啊,并不需要OPC
请指教~~
