Wait for file to be freed by process

Question

How do I wait for the file to be free so that ss.Save() can overwrite it with a new one? If I run this twice close together(ish), I get a generic GDI+

Answer 1

There is no function out there which will allow you to wait on a particular handle / file system location to be available for writing. Sadly, all you can do is poll the handle for writing.
