Hi All, Did not know where to post this....but.... Is there a way that I can have the Development Enviromnent call an external program with the source file as a command line parameter, when you select 'compile' or 'build'. I am writing a simple tool to check for certain type of errors in my source (like a tiny lint tool) so I would not introduce bugs in my code.

The IDE uses the preprocessor as a dll, and doesn't invoke anything via the command line. So I don't know of any way to intercept the call in order to invoke your application. You might be able to add a batch file to your project that runs your checker on your source, but I'm not sure how that would work. You'd probably be better off periodically invoking it yourself rather than having it automatically launched each time you want to compile. Afterall, compiling takes long enough alredy, and most files haven't changed and have already been scanned. -- Chris (TeamB); Back to top Colin B Maharaj Guest Posted: Fri Apr 02, 2004 9:55 am    Post subject: Re: some kind of preprocessor? AH HA! You just gave me an idea. I can hook into the FileChangeNotification service (I have done this kind of thing before) and when the compiler saves the file before compilation, I can scan the file for errors. Thus my application has to run as a background task monitoring the path for my project. Thanks! Quote: and most files haven't changed and have already been scanned.

There's seems to be a possibility to insert your call before actual compilation is done. -- Eugene Mayevski EldoS Corp., CTO Security and networking solutions http://www.eldos.com Back to top Chris Uzdavinis (TeamB) Guest Posted: Fri Apr 02, 2004 3:19 pm    Post subject: Re: some kind of preprocessor?

How long does your scanning take? How well does it work with incomplete source code? While editing files, they might not be in condition to be scanned.... (Maybe my low opinion about auto-invoked tools is showing through... I'm too easily annoyed by interruptions and would shut the auto-invoker off in a hurry. :) -- Chris (TeamB); Back to top Colin B Maharaj Guest Posted: Fri Apr 02, 2004 11:31 pm    Post subject: Re: some kind of preprocessor? Hey Chris, you know what - you make a good point. However I will still go ahead with the project cause there is always a compromise to be made in development. In this case the annoying "popping up" situation is more tolerable than a customer "popping up" and saying that my product is buggy and goes on to say that he will tell every business man they know NOT to purchase my products. Okey, this has not really happened like this as yet, but you can imagine what a few access violations can do to a programmers (or software salesman) reputation - and time. The guy who I deal with, spent 36 hours straight trying to get an installation going without success thinking he was doing something wrong. I then spent about 16 hours or more trying to see if it was a bug - and it was. These incidents I can do without. Again my dealer was doing a presentation demonstrating features in our product. All of a sudden ACCESS VIOLATION!!! He Click Ok and moves onto the next feature - very embarrassing. Buggy code again. I am not a perfect coder - no one is - but when you have been burnt once and twice - and more - boy-oh-boy only the paronoid survives. Hey Chris, I am not trying to "dis" your opinion, as a matter of fact thanks for your insight once again - but I will have to be the one to tolerate an application that can bother the slightly above average Joes like us, in the Builder Community.

You could also just write an OpenTools plugin that hooks the IDE itself, and then the IDE will send you notifications during compiling and such.
