I resolved the issue. Needed to create a type Variant to the array data that I was trying to access. Thx.

This looks like syntax error to me, nothing to do with QuickOPC.
It even tells you "Compile error".

I have not checked this with VB6 actually, but why do you have "Me.myval()" ? "myval()" is a local variable. It should not be prefixed with an object ("Me.").

Best regards

Here a two images. One is there error thrown and the other is the portion of the code where I'm trying to access the array and display the information like your EasyOPC-UA(COM) Demo App.



Thanks for reviewing this.

I'm evaluating your tools and I'm trying to read from our server some values. I can see 5 of them but the 6th one (which is an array of double) causes an error in my vb6 code when using "ReadValue" method. However, I noticed that if I use your app (EasyOPC-UA(COM) Demo App) and enter my Server and Node ID, it returns the information I'm looking for (see attachment). I there any what you could provide the line(s) of vb code that allow for this array of size 30 to properly work? Thx.
