如何在C ++上从CLR捕获事件

Question

I'm running simple dialog on CLR where I fill some textBoxes and press push, So but I need to know when I pressed push.

Here is how I run dialog :

void CFloBossOPCDlg::OnBnClickedButton3()
{
    NewBoi ^ nb = gcnew NewBoi();
    nb->Show();

I can't declare nb as global variable and even I can't declare nb as part of CFloBossOPCDlg so how can I override close event to understand when I need to get filled textboxes ? Thank you.

Answer 1

You can use gcroot to declare handles in native types.

Answer 2

您可以在nb对象上为Closed事件添加事件处理程序。
