Hello,
I managed to write to an integer variable, but now I can’t find the correct syntax for the extensionObject .
For example, I manage to read a value in an extensionObject array like by filling in the following element :
a_pResults.Value.Value.Array.Value.ExtensionObjectArray[0].Body.Binary.Data[4]
and it return the correct value i wanted.
But, when i tried to do an assignment in this same case like this :
nodesToWrite[0].Value.Value.Value.Array.Value.ExtensionObjectArray[0].Body.Binary.Data[4] = 1;
i had an access violation error
My problem is so that i want to know to write in this same variable.
Can someone provide me with the correct syntax to write to this variable for this assignment by example please.
Thank’s

There is a well documented example on how to handle an extension object in the GettingStarted lesson06.
https://documentation.unified-automation.com/uasdkc/1.9.1/html/client_structure_datatypes.html
An example for writing to an array of extension objects including sample code can be found in the server lessons.
