How can I debug a C++ executable that is called externally

Question

I looked online for a solution to this and I would assume this could be done but I cannot seem to find a feasible way of doing this. I have inherited some source code that builds into a executible. The executible consists of C++ and an Fortran library. The file is placed in a simulator enviroment where another program calls the executable. I need to debug some logic errors. The executible cannot run unless the other program calls it. How can I have the other program call it and still access the features of the VS debugger.

Answer 1

If I understood well your question you need to go in VS in Debug-->Attach to Process

Answer 2

VS Debugger has Debug -> Attach to process.
