<t>Dear all, <br/> <br/> we in work are facing with a problem which is were to place the dll (external sdk for video control) for the ewo module. We have placed the corresponding dll-s into a folder on our disk and have set the path (system enviroments) to this path so that the dll-s are visible. Ho...

<t>ok thank you. Could i have one more question ?? from time to time when it crashes i get the following log entry (but not always). <br/> -- my manager is called PVSS00MsduR1 with -num 5<br/> <br/> PVSS00pmon (1), 2017.12.19 10:09:11.588, SYS, WARNING, 39/pmon, Manager PVSS00MiMSql(2) is no longer ...

res_dp = Manager::dpSet(dpId, cFunc.mDynVar);

actually the problem i am solving now is that i need to read lines (the content of the dp of type dyn_string) in wincc oa then append new lines to the text and the send it back to the same datapoint.

Hello, Can somebody please advise me how to read/write a dyn string in API manager ?? Are there some manuals or some examples ??

<r>Thank you for the answer. I also found those topics, however, they did not help me much. The problem I am still having is that I need to pass the window handler into a special function provided by other people which is defined as ( void * handler ). I have tried some conversions to HWND but none ...

<t>I would like to ask how can i define a handler for the ewo object in wincc oa. The problem that i have is that i need to play a live stream of a camera in the ewo object. I was able to connect to the camera and everything looks fine, however the only problem i am having is how to define were the ...

the "ui" manager is running normally and does not crash at all
