widestring to wchar_t bcb6 to BDS2006

[John Mc]

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());

I am unable to reproduce your error. Can you send some code that
reproduces this error?

Here is my example (which compiles without any error) :

void myfunc(wchar_t *pp) {
(pp);
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
WideString ws(L"aaa");

myfunc(ws);
}
