• Mario Cossi Debug build finds MFC80.dll, but Release build doesn't?

  I just transferred a C++ project to VS 2005, and when I run the debug exe both from the IDE and Explorer, it launches correctly. However, if I run the release exe either from the IDE or Explorer, it can't find MFC80.dll. I found that very strange (I haven't put MFC80.dll in the application directories, just made a recursive search just to be sure), and noticed they resided in the Windows\WinSxS directory.

  Is there any way to easily instruct windows to wait for a given thread to complete upon exit of the process in which it was created, other than explicitly calling a function such as WaitForSingleObject at the end of execution As an example, if I create a thread in order to run an asynchronous function, such as one which performs a large calculation and stores the result to a file, logically it should continue to execute until it is finished even ...Show All
