Accessing form data

[question!!]

Hi,

I am new to VC++ programming. I need to create 2 forms and and collect the data that is input in the forms to a class. Now the forms are defined in the form1.h and form2.h files. I have a class "Railway_Input" in the main cpp file. The cpp file runs the form1 by the command

Application::Run(Ipform);
where Ipform is an object of the class for form1. The form2 class is called within the form1.h file.

I cannot access the Ipform->textBox->Text values in the main cpp file, using the Ipform object. As it complains that the attributes are private and I cant access it. I want to know if VC++ provides getter and setter for each of these properties(like textbox,radiobutton) ?If yes what are they called. I did not find a getText() function for textbox, so not sure what member function I should be looking for.

Another way of doing it is declaring the private variables public , which I do not think is right.
If the getter, setters are not provided I could write one for each of the form required elements.

Please let me know what I could do. Also please provide me some good books or links for VC++ programming.

Thanks

No, but it's trivial to write them yourself. You can also force generated controls to be public, but that's not a good practice.

@Narue
Thx for tht!!

@everyone
I do have a new problem though :( .

I am designing a project with two input forms. Now the data in the 2 forms is to be assigned into the class attributes of the class "Railway_Input" which is defined in the .cpp file. The main function looks as folllows. A form1.h file defines the class Form1.

int main(array<System::String ^> ^args)
{
    //Rail_Input RS;
    Form1^ Ipform = gcnew Form1();
    // Enabling Windows XP visual effects before any controls are created
    Application::EnableVisualStyles();
    Application::SetCompatibleTextRenderingDefault(false); 

    // Create the main window and run it
    Application::Run(Ipform);
    //RS.read_sec_mod_rail(Ipform);
    return 0;
}

I first call the forms by the Application::Run command, once the data is entered I need that to be entered in the class Railway_Input. So the Railway_Input attributes are populated from the Ipform object of the form. So could I write the code for that after the Application::Run command?

When I run my program now it compiles but gives me an execution error. But if instead of using the object Ipform in the command Application::Run(IPform), I say Application::Run(gcnew Form1()). The program executes. I have pasted my error below. Please tell me what I am doing wrong.

Also sugest any good books or websites for VC++ project development
