Can you import user32.dll on a 64-bit system?

I have read only richtext box which I would like to also hide the caret. The only suggestions I have seen to do this is import the user32.dll

Code:

---

        [DllImport("user32.dll", EntryPoint = "HideCaret")]
        public static extern long HideCaret(IntPtr hwnd);

---

My question is does anyone know if this will work on a 64-bit system?

Yes it works perfectly on a 64-bit.

I have used the SendMessage function of user32 and have had no problems.
I don't even think there is a user64.dll - correct me if I'm wrong.

After a bit of research I was almost certain that there would be a problem but I had no way of testing it.

Thanks

I also use SendMessage from user32 on a Win7 64 SO and never had problems.
