The error is self-explanitory.  Your TSepSys_GIXImpl class does not 
implement the get_Visible(short*) method that is declared in the ISepSys_GIX 
interface.

After converting an OCX project created with BCB5 into BDS2006 C++, I'm 
receiving the following error:

[C++ Error] atlcom.h(1877): E2353 Class 'CComObject<TSepSys_GIXImpl>' is 
abstract because of '__stdcall ISepSys_GIX::get_Visible(short*)=0'

The project compiles and links without errors using BCB5. I'm using update 2 
of BDS2006. Any suggestions?

Thanks,

Roberto 

Thanks for the prompt response. However, as I mentioned in the previous
message, the project compiled without problems on BCB5. I double-checked
that all the files were migrated into the updated project. Following please
find and excerpt of the source code where the conflicting function is
declared and implemented. Please let me know if you need further information

Regards,

Roberto

Borland started moving away from using "smart" parameter types in TLB

declarations in BCB 6.

Just to let you know that I figured out the problem. During the conversion, 
TOLEBOOL was changed to VARIANT_BOOL in the TLB but not in the 
implementation. Once I changed everything to VARIANT_BOOL, the compilation 
error went away.

Roberto
