File I/O in a Visual C++ GUI

[softwaretime]

Hi everyone, I've been trying to figure out how to make, for example a button in Visual C++ that can take some text from a textbox and save it as a file.

But I don't mean using SaveFileDialog, I want to have it where when the user presses the button it saves the file to a pre-programmed location, and the user wouldn't be able to see anything happen (apart from the file appearing in the location of course). I've tried to use #include <fstream>, but it just generates some errors (not compiling the program.

Any suggestions and advice would be appreciated as it would really help me out. Thanks in advance.

This is what I would do in Qt:

1. Create the button with the GUI tool.
2. Create the text box with the GUI tool.
3. Go to the pushbutton's "released" slot
4. Fill in the function like this:

void MainWindow::on_pushButton_released()
{
    QString str = ui->TextBox->toPlainText();
    
    std::ofstream fout("output.txt");
    fout << str.toStdString();
}

TextBox was the name of my box. ui is created by the GUI editor. Everything is now fully functional though I would have liked to use QFile to be consistent with replacing the standard library.

Sorry, I don't know much about Visual Studio forms.
