Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by captaincookie on increase default string length in queue ^{CODESYS Forge talk (Post)}
I solved it by creating a new element of IElement according to the ElementExample (MyElement) in the ElementCollectionsExamples project. The variables in this element can then be defined in any properties as needed.

Post by timvh on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
See: https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ This contains an application "OnlineChangeSafeLinkedListExample". What you should do is create a new interface which has your "Priority" property. Then your FB should extend the base element function block and implement your own interface: E.g. FUNCTION_BLOCK MyElement EXTENDS COL.LinkedListElementBase IMPLEMENTS I_MyInterface Then the __QUERYINTERFACE does the magic to check if your "element" also implements your interface. Something like this: // Compares this element with itfElement. // Returns 0 if the elements are equal, < 0 if the element is less than itfElement, // > 0 if the element is greater than itfElement. // This method will be called from sorted collections (e.g. |COL.SortedList|) to sort the elements. // IMPORTANT: The underlying value to be compared with MUST NOT be changed during the lifecycle of the object. METHOD ElementCompareTo : INT VAR_INPUT (* The element to compare*) itfElement : COL.IElement; END_VAR VAR itfIntElement : I_MyInterface; xResult : BOOL; END_VAR // We use integer iInt1 for sorting. xResult := __QUERYINTERFACE(itfElement, itfIntElement); IF xResult THEN IF iInt1 < itfIntElement.Priority THEN ElementCompareTo := -1; ELSIF iInt1 > itfIntElement.Priority THEN ElementCompareTo := 1; ELSE ElementCompareTo := 0; END_IF ELSE ElementCompareTo := -1; END_IF

Post by hazarath on How extract JSONElement containing Array data ^{CODESYS Forge talk (Post)}
I want to extract each element of an Array. Can someone help me with this. When I use JSONElementToString (part of JSON Utilities SL), I am seeing output as "ARRAY" instead of actual data. Here is the JSON content that I want to read : { "value1Unit": { "units": "M" }, "data": { "stepSize": 300.23, "points": [6,8] } } I would like to read each item of the element "points" i.e. 6 and 8. Here is the code I used, // Reading the content as JSON reader ( xExecute := execute , pwData := ADR ( converted_value ), jsonData := jsonDataStorage ); // Get the JSON Element jsonDataStorage.FindFirstValueByKey( wsKey := fidKeyVar, diStartIndex := searchElem, jsonElement => jsonElement ); JSON.JSONElementToString ( element := jsonElement , wsResult := valueWstring ); The content of the output of valueWstring is shown as "ARRAY" instead of the array items i.e. 6 and 8 Please can someone help me.

Hello Is it possible to view a camera RTSP feed in a visualization? It seems as though the browser element doesn't support this and we are trying to replicate an example using the ActivX element with no luck. We are using the Windows Control Win x64 device with a camera connected via LAN. If it is possible, can you provide some instructions please. Thank you

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

Post by jeffersonhui on SP20 Visualization Element Dynamic Colors ^{CODESYS Forge talk (Post)}
I am using Codesys SP20 patch 5 and in a visualization element, the "Color variables" section does not have a section to set up dynamic color values linked to variables. In a previous version (SP18), I get the option to add variables for Normal & Alarm state colors. Does anyone know how to get the dynamic color variables to work?

Post by peterkcontrols on Making a Visu Element normally invisible and visible if variable is true ^{CODESYS Forge talk (Post)}
Hello I would like an element in my visu to be only visible when a certain Variable is true, currently it is only capable of being normally visible and then invisible if a certain variable is true. Is this possible without programming a new variable to be the opposite of my desired control variable? Thanks.
