Thread: fstream - Console vs. Windows

I'm writing a Windows program in VC++.NET and I want to use the fstream object. This worked fine as a console app.

This is a Windows Form Application so I could take advantage of the Drag and drop functionality.

I included the fstream file

Code:

#include <fstream>

and I want to say

Code:

fstream reader;

and it tells me that ''reader' is an undeclared identifier' and then tells me ''fstream' is an undeclared identifier!' What is wrong with it? Why does it work in a console app and not in a windows app? There are many more errors that I get, it seems many things that work just fine in a console app do not work in a Windows app. What's wrong?

Are you sure that it is not a namespace problem?

I don't know. In the console app I did this...

Code:

using namespace std;

VC++.NET puts in a lot of other namespaces like System, System:: Data, System:: Drawing, etc...

I don't really know how to work with namespaces I'm kind of new... It won't let me type

Code:

using namespace std;

it says 'a namespace with this name does not exist'.

i havent done any GUI programming for a couple years now...but as far as I know the std namespace should always exist...it is part of the heart and core of the C++ standard libraries.

try declaring your fstream with std:: in front. example:

Code:

std::ifstream reader;

Code:

std::ifstream reader;

If I do that it gives me the same previous errors plus more errors, saying 'std is not a class or namespace name.'

I know its not a problem like the std namespace is missing or something because it works fine in console programs.

How's this line of code?

Code:

VisualStudios = annoying;

Any other suggestions?
