Hello.

Please have a look here: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...0Complex%20Data%20writing.html .

I think that instead of writing the StructuredData directly, the code should create a UAGenericObject with its GenericData set to what you are writing now; and then use this UAGenericObject as a value for writing.

Best regards

StructuredData cannot be stored in a Variant object was created by ZParham
Hello!

I have a case that seems like it may be related to this post: opclabs.com/forum/quickopc-ua18/3267-easyuaclient-write-uarange-and-uaeuinformation

We have a customer who is attempting to use complex data within method calls, and is receiving the following error:
https://ibb.co/LNtYbKG

Attached is the code snippet of what is being done. The only thing that sticks out to me is that he is specifying the typecodes as something other than typecode.empty. Would those cause this error, or have I missed something simple here?

Thank you in advance!
Zach
