wxWidgets and PostgreSQL

[Ayen Yang]

Dear VZ,

I've just tried to use wxString::FromAscii() and the result is still
the same. I also tried wxString::FromUTF8() and the result is an empty
wxString.

I'm a newbie in wxWidgets programming. Could you tell me how to put
the value to a wxString:
- if the PQgetvalue() returns UTF8?
- if the PQgetvalue() returns ASCII?

Thank you very much.

Regards,
Ayen
