I searched Google for "cppbuilder variant exec debug av" and this is the link (one line, of course): http://groups.google.com/group/borland.public.cppbuilder.activex/ msg/6252a8bcadff64c4?dmode=source > You mentioned in an earlier post that this is more a "VB" solution.

Is this perhaps not > the case? I don't know if it's more/less optimal than using the VCL classes found in ADODB or using the COM classes in ADOINT. I'm sure there are some hidden features that are much easier to get at using the technique you are using. The "VB way" is definitely more flexible since you can access any OLE/COM interface without making a class or importing a DLL or other LIB and header. However, I doubt that you will be able to use TDataSource or the other DB components/controls through this Variant interface (I'm prepared to eat those words if someone else can contradict me). If this is not a requirement for you then this won't be an issue. I'm afraid that at this point my information on this problem is maxed out and with it my ability to help "fix" it. For now you may have to leave your app in "debug" mode. I have one released product that we had to do that. There was no time to hunt for the cause of an infrequent error we were experiencing in debug mode. Fortunately, this only adds about 2K to the application so is not really a big deal. Perhaps you can contact Wayne Smith and ask him if he was ever successful in finding his problem. - Clayton
