Form values into a function

[WillT]

Hi,

I've got a function which simply has the following code:

MT4_EXPFUNC void __stdcall test(void)
  {
	Application::EnableVisualStyles();
	Application::SetCompatibleTextRenderingDefault(false); 

	// Create the main window and run it
	Form ^ frm = gcnew Form();
	Application::Run(frm);
	//return 0;
  }

This does what is expected - it opens the form. Now what I want to do after Application::Run(frm) is return the values of each TextBox.

I assume something like

char bla = frm->textbox1->Text

However, this errors with

1>test4.cpp(20): error C2039: 'textbox1' : is not a member of 'System::Windows::Forms::Form'
1>          c:\program files (x86)\reference assemblies\microsoft\framework\.netframework\v4.0\system.windows.forms.dll : see declaration of 'System::Windows::Forms::Form'
1>test4.cpp(20): error C2227: left of '->Text' must point to class/struct/union/generic type

Can someone help me get the value of the text box into my function?

Thanks.
