Hi I am not sure if this question belongs here in the WinCC thread or if it should be in the PCS7 thread but I'll try here first. I have a PCS7 project which opens a self-made picture window for certain kind of objects in the process which is being controlled. The window is opened using the SSMOpenTopFieldFixedSize c-function. So far things work ok. But after that I need to set the TagPrefix property of the opened picture window so that the window links to the right tags of the process object that the window is currently opened for. The SetTagPrefix c-function is used for this in the mouse left click event handler that opened the window. SetTagPrefix's definition looks like this: SetTagPrefix( lpszPictureName, lpszObjectName, szTagPrefix ); In an ordinary WinCC project you always know from which picture window your current window is opened and can supply that picture name to the lpszObjectName parameter. In a PCS7 project the PCS7 system opens your window on any of its @TOPxx windows. Now my question is how I can find out from which @TOP window my own self-made window is opened so that I can supply that name as a parameter to SetTagPrefix. I have not been able to find the answer so far in FAQ:s, the forum or on my own. This old thread is also asking the same question but withouta complete answer: /tf/WW/en/Posts/8241 Thank you in advance for your help, Regards Cka. |
