    Pass a List<double>^ to an opening Form

    In wonder if I can pass a List<double> to another Form when this form opens ?
    Code:
    List<double>^ ExampleList = gcnew List<double>; //ExampleList has for example 50 elements

    With the code below I can pass a String^ from Form1 to Form2 that opens.
    I get this passed string as in this example: getstring1.

    I wonder if it is possible to pass a List in this same way or any simular way ?
    Thank you...

    Code:
    String^ string1;
    Form2 ^form2 = gcnew Form2(string1); //Pass string1 to the opening Form2
    form2->Show();
    Code:
    Form2( String^ getstring1)
    {
    	InitializeComponent();
    	//
    	//TODO: Add the constructor code here
    	//
    }

    Code:
    Form2( List<double>^ list)
    {
    	InitializeComponent();
    	//
    	//TODO: Add the constructor code here
    	//
    }
    Is that what you mean? You can do this with any type...
    By the way what does ^ mean? Reference/pointer I guess? It is Visual C++

    It's some kind of Microsoft crapification of the C++ language. I usually just skip over posts that use "Managed C++".

    ^ and % are the same as * and & except they are used to differentiate between managed types and native types. this was added in C++/CLI. managed C++ is the older version which used */& for both managed/native and it was extremely confusing so they changed it.

    So, to conclude you can pass anything you want with a reference and use it normally.
