How to use multi byte character set in vs2008 ATL

[Robe]

when create atl project, then set multi-byte character, compile, I got error: DllInstall: error C2440: 'initializing' : cannot convert from 'const char [5]' to 'const wchar_t []' then try to modify: form STDAPI DllInstall(BOOL bInstall, LPCWSTR pszCmdLine) to STDAPI DllInstall(BOOL bInstall, LPCSTR pszCmdLine) compile: error C2733: second C linkage of overloaded function 'DllInstall' not allowed any ideas? thanks!

Another way to solve your problem would be to use the system function MultibyteToWideChar to convert your message to unicode when you call DllInstall. (If you're in charge of calling it, that is.) The other solution I can think of would be to just use a unicode project, depending on how much you would have to change for it. Nathan

You can change the static const wchar_t szUserSwitch[] = _T("user"); with static const wchar_t szUserSwitch[] = L"user"; regards
