Did you ever have the same problem: if you want to compiler a Win32 program with UNICODE
/_UNICODE
defined, for some reason the argv
vector does not contain a single proper argument?! This happens in particular in DDK/WDK projects. I was sick of it, so here’s a little wrapper class that does almost nothing if UNICODE
/_UNICODE
are not defined and otherwise simply fills new values into the argc
and argv
parameters to the main
/wmain
function. The use is as simple as can be, make sure shell32.lib is linked in and include ShellAPI.h, then simply instantiate the class within (w)main like this:
CTcharArgs dummy(argc, argv);
Easy, huh? Here’s the class:
class CTcharArgs { public: CTcharArgs(int &argc, _TCHAR** &argv) #if defined(UNICODE) || defined(_UNICODE) : m_argv(::CommandLineToArgvW(::GetCommandLine(), &m_argc)) #endif // UNICODE { #if defined(UNICODE) || defined(_UNICODE) argc = m_argc; argv = m_argv; #endif // UNICODE } #if defined(UNICODE) || defined(_UNICODE) ~CTcharArgs() { if(m_argv) { ::LocalFree(reinterpret_cast(m_argv)); } } private: LPWSTR* m_argv; int m_argc; #endif // UNICODE };

PS: Should even be compatible with cross-platform code (in which case _TCHAR will probably be an alias for char) đ
BTW: The proper way is to set
UNICODE=1
in the
SOURCES
file đ
