Post by timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To get the current visu for all your individual web clients, you could iterate over them, using the same library 1) Create a new function block which implements VU.IVisualizationClientIteration 2) Create an instance of this function block + add an instance of the "iterate" function block fbIterateCallBack : FB_IterateOverClients; // this implements VU.IVisualizationClientIteration fbVuIterate : VU.FbIterateClients; // this FB iterates over all clients 3) Call the fbVuIterate and set the reference to the call back FB. Then it will automatically call the method "HandleClient" of this function block. fbVuIterate( xExecute:= NOT fbVuIterate.xDone, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, eError=> , itfIterationCallback:= fbIterateCallBack); In the HandleClients method you can use the property of the interface of your webclient to which page it is currently on: sCurrentVisuOfClient := itfClient.CurrentVisuName; 4) Optionally from here you could also set the visu for the webclient, but this might be obsolete, because the other function block is now available... xQueryOK : BOOL; xChangePage : BOOL; itfVisuClientRawData : VU.IVisualizationClientRaw; xQueryOK := __QUERYINTERFACE(itfClient, itfVisuClientRawData); IF xQueryOK AND xChangePage THEN VisuElems.g_VisuManager.SetMainVisu(pClientData := itfVisuClientRawData.ClientDataPointer, stVisu := 'Visu2'); xChangePage := FALSE; END_IF

Post by simotion on Online view : code is scanned ^{CODESYS Forge talk (Post)}
If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Post by timvh on No source code available for this object ^{CODESYS Forge talk (Post)}
The message means that you (CODESYS) tries to open the function block, but this is not possible because the library which contains the FB is compiled. You either get this when you try to manually open the function block (while editing the application), but it could also happen that an exception occurs in the running application and CODESYS tries to show the location where it occured. If it happened in an FB of the compiled library, it cannot show this and you could get this message too.
