Oracle Forms

Hi everyone,

I have encountered a problem where combo boxes in applications will generate an Access Violation in VCL60.BPL (a Borland package). However, this seems to only happen on machines where Oracle Forms 8i and C++Builder 6 are installed, and it even occurs with combo boxes in non-Borland applications.

Based on what I've seen, I'm thinking maybe using Forms 8i and C++Builder 6 together causes some sort of conflict in Windows common controls like the combo box.

So, my questions are...

*****
Does anyone here use Forms 8i and C++Builder 6 together? If so, have you run into any similar compatibility issues?

*****
VCL60.BPL is a standard Borland designtime package for Windows applications (hence its relationship to the combo box). Is there an equivalent package in Forms 8i? If so, what is it?

For reference, this has been observed on Windows NT and Windows 2000, and presumably occurs on other Windows operating systems as well. The combo boxes will work fine for a while (sometimes up to a day) before the Access Violation in VCL60.BPL occurs. However, once the Access Violation occurs, it will occur anytime a combo box is used, and it will occur in all applications, not just Borland ones. The only way to "reset" the behavior is to reboot the system.

I know this is a long shot, but thought I'd try asking anyway. I'm not necessarily implying it's an Oracle problem, as it could well be a Borland problem, but regardless of fault, I'm hopeful that someone has heard of this before. Out of nearly 50 test systems (all of which have C++Builder 6), only a very small handful exhibit this behavior, and those are the only systems running Forms 8i, so there's a strong correlation and not much else.

Thanks a lot for any feedback and suggestions. It's greatly appreciated.
