I'm experimenting with embedding a Fox form inside of a WPF form. For the most part, I've got it working, but I having an issue with the keyboard focus. I can get focus to the VFP form, and I can type characters in a textbox, but there is no blinking keyboard cursor. Here is the C# code I'm using:

[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
[DllImport("user32.dll")]
static extern IntPtr SetFocus(IntPtr hWnd);
       
...

SetParent(hWndFox, (IntPtr) hwndParent);
SetFocus(hWndFox);  // this works, but where's the keyboard cursor?

Can any of you WinAPI experts see what I'm missing?

Thanks.
