Labwindows/CVI, TestStand, MultiThreading with same DLL

[JayCeeBee]

I am writing a dll in Labwindows/CVI that will be used with TestStand. I would like TestStand to run 10 "tests" at the same time by using the multithreading capabilities. Each test will use the same DLL at the same time however. I have run into some data protection problems (more than one thread writing to the same dynamically created array, etc.). My question is, what is the most convenient/effecient way around this problem. I do not want the threads to "share" the same array or any other resource, I would like each thread to have their own individual array/resource.

Thanks in advance.

Jared,

Have you considered creating the array in TestStand and then passing a reference to the DLL? You can create arrays with the "initially empty" property checked and then call PropertyObject.SetNumElements to dynamically set the bounds of the array.

Hope that helps.
