The problem is that you're creating ListCtrl1 as a local variable. When the method is done, it will be destroyed again.

You have to create the wxListCtrl in the constructor of the frame and store the pointer in a member variable. Then you can fill the control in the button event handler.
Use the source, Luke!

This is based on the "minimal" sample and it's as simple as it gets. Your original code didn't show what kind of list control you wanted, so i used the wxLC_LIST style.

This is elementary stuff, i recommend to study a wxWidgets tutorial and some of the samples so you get an idea of the basic structure of a wxWidgets application.

}
it is my source , just Add a list of the base frame,
i want click the "openfile"button and select wav file(use filedialog)

As you advice, Learning to watching the tutorial. but It takes longer to learn how to use.
