Do you have the latest update of Delphi 7 installed? If yes, then you have an unstable component installed.

I find Delphi 2005 to be a bit more reliable in that matter. But, since I don't know what kind of problems you're having with Delphi 7, it could be that some of them are a result of bad third-party code. -- Danijel Tkalcec RealThinClient Components http://www.realthinclient.com Back to top Robert Parrish Guest Posted: Wed Jul 27, 2005 10:10 pm    Post subject: Re: Delphi 7 vs Delphi 2005 It probably is a bad third party component but I can't find out which one because Delphi just closes with no indication of an error.

And to eliminate the problems with debugging multithreaded code, RTC Core connection components have a property called "MultiThreaded", which I can change to False when debugging and return back to True for deployment ) -- Danijel Tkalcec RealThinClient Components http://www.realthinclient.com Back to top Brian Moelk Guest Posted: Wed Jul 27, 2005 10:16 pm    Post subject: Re: Delphi 7 vs Delphi 2005 Quote: It probably is a bad third party component but I can't find out which one because Delphi just closes with no indication of an error.

I've experienced Windows killing an app, without giving it a chance to raise an exception when app code produced nasty access violations in Windows Kernel. But you're right, you first got to find out which components are causing Delphi to crash. After that, the only thing you can do is contact the component vendor and ask for support. -- Danijel Tkalcec RealThinClient Components http://www.realthinclient.com Back to top Robert Parrish Guest Posted: Wed Jul 27, 2005 11:00 pm    Post subject: Re: Delphi 7 vs Delphi 2005 The app runs fine when it compiles. The problem is it dies during the compile and no exception is thrown. BTW it is a single thread app. It is not always changes to the same form that causes it to crash. I wasn't saving the editor files so I lost some changes. I have since turned that on!

I suggest removing sections of code until it compiles OK, keeping track of what you've removed.

It's as if I clicked on the close button in Delphi. There is an outside chance it is related to a Microsoft update/patch. Has this happened recently? I had D6/D7 closing and crashing all the time a few months ago after a MS patch was installed. Removing the patch, and no longer accepting auto updates, completely fixed the problem. I don't remember the details now, but there was a thread in one of the Delphi (IDE ??) newsgroups about this. -- Kevin Powick Back to top Iwalewa Guest Posted: Thu Jul 28, 2005 12:49 am    Post subject: Re: Delphi 7 vs Delphi 2005 Quote: The app runs fine when it compiles. The problem is it dies during the compile and no exception is thrown. Corrupted files maybe? I had similar problem but with D5 and turned out to be a corrupted DataModule. Once recreated, the problem disappeared.

It's as if I clicked on the close button in Delphi. I use a lot of third party controls in this app. In addition to the other suggestions in this thread, you could use a virtual PC product such as VMWare. Install Delphi, do a test project. Now load a copy of your project that is giving you trouble, and strip it down to a skeleton (the minimum number of units for it to work at all, and using no or few 3rd party components). Then, one by one, install your 3rd aprty components, and add the code that uses them back in to the project.
