SetPriorityClass and SetThreadPriority.

This code does not error out but Task Manager does not show the priority as high ....

if ( !SetThreadPriority( GetCurrentThread(),    THREAD_PRIORITY_HIGHEST ))
{
   result = GetLastError();
   sprintf( buffer, "Error [%d]", result );
   Application->MessageBox( buffer, APP_TITLE, MB_OK );
}

if I use Application->Handle, it errors out and reports a bad handle ...

That's because the Task Manager shows the application's priority class, not 
thread priority.

That's because SetThreadPriority taks a thread handle, not an application 
handle.  SetPriorityClass is the one that takes an application handle.
