Solution
You can achieve it by below steps.
It is recommended to use the A variants for Win32 API calls rather than the W variants, because W variants are Wide / Unicode and A variants are plain ANSI.
- In TestStand, create a C++/DLL Action Step.
- Select the DLL that contains the Win32 API call. (This might require searching online.)
- Select the method which you want to use and choose the A variant.
- When you get this popup, ignore it. (TestStand is complaining that it doesn't know the prototype and cannot autocreate the required parameters.)
- Add parameters and configure them to match TestStand data types to Win32 API data types.
Here is a list of data types in the Win32 API.

Here is a summary of common data types and how they map to TestStand
