The Problems: What's going wrong in my AppleEvent routines?!?!?!?The Solution: AETracker!
AETracker is an INIT/CDev that allows you to log AppleEvent activity on your system. You can watch as much or as little AppleEvent manager (AEM) information as you like, and pull a little info or a lot of information about what's happening. AETracker provides many levels of tracking, fully user configurable. AETracker lets you track the inputs and outputs to all your AEM calls, and will show you exactly where errors are occurring. Another very helpful use for AETracker is to sno0p other people's applications, you can get a full track of what AEM activity other applications are doing.
And here's the source code. For those of you brave enough to look private C.K. code straight in the face, here you are. The ugly assembly details of patching the AppleEvent manager to parse through all the stuff flying around your system. Please feel free to use this code in any way you wish, with the following restrictions; * if you use more than 25 lines of this code, please give me credit ("some code by C.K. Haun") * No commercial AppleEvent tracking application can be derived from this code * You have all the responsibility for any errors
