access class object in multiple threads

Hi!

I realized that objects are by value, so how to realize my problem? I can not figure out how to get the reference to my object.

Search for "DVR" and "LVOOP".

There are plenty of discussions on teh topic.

OOP in LabVIEW not based on by reference like in c++, but is based on by value. 

So you will not be able to get any reference to your OOP object.

So what is happening in your code, is that a the fork of the object wire your are creating to copies of your object.

One thing you could do is have DVR in the private data of the class. Make a method that initialize the DVR, and call that method before the fork.

The in your read/write method, make use of the DVR to share the data.

Thanks to both of you!

It took me some time to get it all right but now it works.

So I now have to redefine all my inputs and outputs for the class functions.

If I understand it correctly, there are no 'new vi from template' for creating read/write vi.s for classes with DVR.
