Reparent non-modal form to existing application

Question

I would like to be able to show a non-modal form in an already existing application. At the moment I can do something like:

myform.ShowDialog(handleToApp);
         


        

Answer 1

I found what I was looking for, you have to make a class which looks like this:

public class MapinfoWindowHandle : System.Windows.Forms.IWin32Window
    {
        private IntPtr handle;
        public MapinfoWindowHandle(IntPtr hWnd)
        {
            handle = hWnd;
        }

        #region IWin32Window Members

        IntPtr System.Windows.Forms.IWin32Window.Handle
        {
            get { return handle; }
        }

        #endregion
    }

and then you can do this:

IntPtr windowhandle = new IntPtr(hWnd);
MyForm.Show(new MapinfoWindowHandle(windowhandle));

How about a simple myForm.Show()?
