title: Close access to a dll in Excel
body: <p>I'm currently working on a project using C++ and Excel. I made a DLL to export a C++ function in Excel. My problem is that when I test my function in Excel and I want to modify my DLL, I need to quit Excel because it's still running the .dll file, and Visual studio C++ can't delete the previous DLL to make an other.</p>
  
  <p>It's a bit annoying to close and launch again Excel everytime so I would like to know if there is a way to close access to the Dll when the VBA script is finished.</p>
  
  <p>Thanks!</p>
