It looks like your while loop does not give the main window thread any chance to process its message queue.

moreover, know that the Win32 API is written in C, not C++, so exceptions are unknown in C.

Would the CreateDirectory function throw an exception if the directory that it must create already exists?

BOOL bCreated = CreateDirectory(..);//Call function
if (bCreated ==FALSE )
{
  if (GetLastError() == ERROR_ALREADY_EXISTS)
{
 //this will be true
}
