Ok, I see what's the problem here. The I/O field output value was oringinally controled by a tag name. When I type a tag name ( example: archive\ACV_05_0029.qPOS). Trend with that tag name will show up on the OnlineTrendControl. Since your code applied, I/O field is not controled by Tag name anymore. because events "output change" leads to "OnTrendPropertyChaged", and It was finally set by the code of yours: SetPropChar (lpszPictureName, szObjName,"OutputValue", pszTrendTagName); Next time I type a tag to I/O field (archive\ACV_05_0029.qPOS), it's just not working. The difference here was that i'm using tag to control I/O and you're not.
