  2. Open the folder that has the DLL file and Select ” Export to Project”- You can use any other program to view your code, and if you find that a line of code needs to be changed then you can right-click the DLL file to export it to Visual Studio. This will take the DLL file from the program that you are using and then it will move it into the Visual Studio.
  3. Edit the Code- If you are using Visual Studio, then you may edit the code to run the functions that you want. Visual Studio can also be used to view the DLL file without editing it.
