I have some code that looks something like this:

 AnsiString strName;
WideString nameWideStr;

// some code to build strName

ThirdPartyFunc1(nameWideStr);

This has worked nicely under BCB 6.  Now I am trying to compile the code 
under BDS2006 and get the following errors:

[C++ Error] GEMUtils.cpp(83): E2034 Cannot convert 'WideString' to 'wchar_t 
*'
[C++ Error] GEMUtils.cpp(83): E2342 Type mismatch in parameter 'name' 
(wanted 'wchar_t *', got 'WideString')

What do I have to do to get this to work under BDS2006?

Thanks in advance for your help.

That should be working fine.  WideString has a BSTR conversion operator 
defined, and BSTR is a typedef for wchar_t*.

If the conversion operator is not working properly, you can call the 
WideString::c_bstr() method explicitally:

    ThirdPartyFunc1(nameWideStr.c_bstr());
