I think the file that is being created is an .asm file, any idea how to do this in Visual Studio when you do the assembly?
Configuration Properties -> C/C++ -> Output Files
No Listing
Project-> Properties-> Configuration Properties-> C / C ++ → Output Files
There you should see the option to exit the assembler.
John.
Or, if you use the Visual Studio command line,
cl.exe / Fa [assembler file name]
If you just want to view the assembler code in the IDE, you can run the debugger and then select the Go To Dissassembly option from the right-click menu.
