I/O Problems

Hi all!
Im new to c++ but I used to use c# and made the transition for standalone .exe files.

Im working on a program that uses I/O and I get errors when trying to open, and write to a file with concatenated parameters.

E.g

Code:

---

        ofstream file;
        file.open("C:\\" + textBox->Text + ".txt");
        file << textBox2->Text;
        file.close();

---

The compiler has an error for the opening and writing line of my code.
The errors say

Code:

---

Cannot convert parameter 1 from 'System::String ^' to 'const wchar_t *'

"No user-defined-conversion operator available,                   
 or Cannot convert a managed type to an unmanaged type"

---

and it also has an error that might be resolved with the first one

Code:

---

<< illegal for class

---

I tried to add as much detail as I could :S

Thanks for any help

Do you mean that you don't want to rely upon the .NET Framework? If that's the case then you should avoid Managed C++ (or C++/CLI).

Managed C++

Umm how do you write unmanaged code then?
Is it a different language altogether?

Well, Managed/CLI is an extension to standard C++. There are both additions to the language itself, and you can utilize the .NET Framework.

When you create a new project you can choose between different project types. Such as 'Managed', 'MFC', 'Win32' etc.. To create a plain old standard non-visual project I would choose a 'Win32 Console Application'.

Noooo

So I basically lose the IDE :(
Does this mean I have to use different code?

One more thing do I have to compile it differently to have it not rely on the .NET framework?
