Visual C++ Scope Bug?

[Guest_imported]

Hi,

I´ve a member function, CreateFile in my BS_Directory class which Visual C++ seems to confuse with its CreateFile somehow..

in class BS_Directory definition I´ve:
BS_File *CreateFile(string name, BS_File::BS_FileAccess access = BS_File::BS_ReadAccess);


And in my BS_File.cpp file I´ve the implementation of my CreateFile:

BS_File *BS_Directory::CreateFile(string name, BS_File::BS_FileAccess access)
{
...

ms_file = ::CreateFile(...);
...
}

I get the following error from Visual C++:

bs_file.cpp(321) : error C2039: 'CreateFileA' : is not a member of 'BS_Directory'

Now this is weird to say the least...
Thanks in advance!

I´ve tried to change the name to CreateAFile and then all works, so it seems to be some confusions with Windows CreateFile...

There is nothing weird about that.
As you know there is no effective CreateFile function - it only exists:
CreateFileA - normal
CreateFileW - for unicode, wide chars and so on.

In one of the predefined header files that you include (probably windows.h) there is a phrase like:

#ifdef __UNICODE
#define CreateFile CreateFileW
#else
#define CreateFile CreateFileA
#endif

So, these are the advantages and disadvantages of using defines.

In the future try to avoid using names for functions that resembles some of the system.

HTH, s-)
