Cannot use ofstream members

[UnknownPerson]

Someone please help:

In one of my coding works, I needed a class wich manipulated records on a file. As such, I made a ostream member as in:

class SomeClass {
ostream TheFile;
};

To my surprise, any attemp to TheFile.open(....) fails, no matter what the parameters. Anyone have a clue?. I made the following test:

SomeClass::OpenSomeFile(std::string& Name)
{
TheFile.open(Name.c_str()); // FAILS!!!!
ostream SomeOtheFile(Name.c_str()); // Works perfectly
}

Any ideas???

Notes: Using MSVC++ v5.0 Enterprise. I sent this message to 3 different C++ related discussion rooms.

I´m sorry, just to correct some typos in the post.
Corrections are:

class SomeClass {
ofstream TheFile;
};

And:

SomeClass::OpenSomeFile(std::string& Name)
{
TheFile.open(Name.c_str()); // FAILS!!!!
ofstream SomeOtheFile(Name.c_str()); // Works perfectly
}

This is only a correction of my typos. The problem still exists. Any help?
