Re: [Dev-C++] WinMain()

[Per W. <pw...@ia...>]

I haven't done a lot of work with Developer Studio .NET, so I can't say
about your problem with a console + GUI but anyway...

The original main() only takes 8-bit characters as parameters, making it
unsuitable for unicode programs.

To better support unicode, you now get a
int _tmain(int argc, _TCHAR* argv[]);

where _tmain will conditionally compile to
  int main(int argc,char* argv[]);
or
  int wmain(int argc,wchar_t* argv[]);
depending on if you compile your program with _UNICODE defined.

I can't say what difference it is between tmain() and _tmain(). I only
have a DevStudio 6.0 in front of me right now, and it only have the _tmain
declaration.

Normally, it is a question of linker flags if the program expects to find
a main() or a WinMain(), where main() is expected for console
apptiocations and WinMain() for GUI applications.

I have had a couple of DevStudio 6 projects goof up quite a lot when
letting DevStudio upgrade them to DevStudio.NET. A number of compiler and
linker settings have become quite interesting :-)
