Which win32 app? You need to be specific. If you are talking about your own app then raise a separate post as suggested.i have made a win32 App with VS2017 Express which run under Windows but not under ROS
...can someone tell me how to fix it to run under ROS (i'm not a C# Programmer)
If you are talking about winfile then please state precisely what you are doing... If English is not your first language then that's fine. Just take it slowly and add all the information so there is no confusion.
