Drag an Drop in MDI child forms

[Torsten Zachert]

Hi,

I have to Drag an Drop data between 2 listviews in MDI child forms. How do I
activate the target child form, if the mouse is over.

using System.Runtime. InteropServices ;

[DllImport ("user32.dll ")]
public static extern int SendMessage(Int Ptr hWnd, int Msg, int wParam, int
lParam);

private const int WM_NCACTIVATE = 0x0086;
// to activate
SendMessage(Chi ld.Handle, WM_NCACTIVATE, 1, 0);

// to deactivate
SendMessage(Chi ld.Handle, WM_NCACTIVATE, 0, 0);

there's also a select property, that's not intended for use from "your"
code.

Child.Select();

Maybe someone knows why it's not intended from "your" code?
