How do you cast a System::String __gc * to an int?

I've got numbers 1-12 in a listbox. I want the user to be able to
click on a number in the listbox and the event fired takes the
number the user clicked and puts it into a case statement which
runs a function with certain parameters, depending on which
number it was. Any clue?

Thanks for any suggestions.

You don't. As mentioned in your other thread on this topic you use the selected index.

int i = listboxRadStr->SelectedIndex;

switch (i)
{
    case -1:
        // No item selected
        break;

    case 0:
        // First item selected (1)
        break;

    case 1:
        // Second item selected (2)
        break;

     ...
}

As for adding multiple items, you could use a loop:

for (int i = 1;i <= 12;i++)
{
    listboxRadStr->items->Add(i.ToString());
}

C++ with managed extensions has not been widely adopted and samples are hard to come by, even in the MS documentation. You may want to look into switching to C# for your CLR work.

As I have not used MC++, I can't guarantee that the code I have posted will compile.

Thank you so much anonytmouse ! That simple little thing was hanging me up for so long and now it works! I appreciate it.

Now, can you tell me how to empty the contents of a listbox programmatically?

listboxRadStr->Clear?

Try:

listboxRadStr->Items->Clear();
