in reply to Question on Win32::Process

NORMAL_PRIORITY_CLASS is exactly that. Use the normal priority for this process. Alternatives to are IDLE_, HIGH_ and REALTIME_PRIORITY_CLASS constants. These are the same values as you can set using the "set priority" submenu from the Task Manager context menu. On XP/2003 there are also ABOVE_NORMAL_PRIORITY and BELOW_NORMAL_PRIORITY, but these constants are not (yet) exported by Win32::Process.

Simplistically, when a higher priority task becomes eligible to run, it will take precedence over lower priority processes. Be aware that changing these values to other than NORMAL is inadvisable unless you have good reasons, and the process is written to operate properly at the chosen level.

For the full nitty gritty, see the MSDN explanations.

According to this documentation, the CREATE_NO_WINDOW flag is ignored!

      Guessing, I would say that the CREATE_NO_WINDOW constant was added to the Win32 header files for some envisaged use that never got added, or was rejected for some reason.

      The reason it is exported by Win32::Process is because it was discussed and documented in the MS documentation for the call, and because it might do something useful at some point in the future. As it stands, it will just do nothing.
