(This post is from my old, old, super old site. My views have changed over the years, hopefully my writing has improved, and there is now more than a handful of folks reading my site. Enjoy.)

I just put this in VP's main.m file. Someone else might find it useful:

#ifdef DEBUG

NSWorkspace *workspace = [NSWorkspace sharedWorkspace]; NSArray *launchedApplications = [workspace launchedApplications];

for (NSDictionary *junk in launchedApplications) {     if ([@"com.flyingmeat.VoodooPad_Pro" isEqualToString:[junk objectForKey:@"NSApplicationBundleIdentifier"]]) {         NSLog(@"It's already running you moron");                  ProcessSerialNumber psn;         psn.highLongOfPSN = [[junk objectForKey:@"NSApplicationProcessSerialNumberHigh"] intValue];         psn.lowLongOfPSN = [[junk objectForKey:@"NSApplicationProcessSerialNumberLow"] intValue];         SetFrontProcess( &psn );                  NSBeep();         sleep(.5f); // let the beep actually happen.                  return 0;     } }

#endif
