Hi,
Firstly, I was wondering why you were creating a type library for a function that I assume is going to be called using the CVI Standard Prototype Adapter from TestStand. Since the prototype is fixed, there is no real benefit to creating a type library. You simply need to export the function.
However, if you wish to fix this, you should be able to simply add "typedef" to the IDispatch declartion inside of the stdtst.h header file. This should take care of the error.
Please let me know if this works, and why it is that you are creating a type library. Thanks!
Bob
