cue banner not working

Question

I am using this code to set watermark for textbox but watermark now showing with no error.

here is the code:

        // cue banner;
        private const uint ECM_FIRST = 0x1500;
        private const uint EM_SETCUEBANNER = ECM_FIRST + 1;

        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, uint wParam, [MarshalAs(UnmanagedType.LPWStr)] string lParam);

and in Form_Load:

            SendMessage(txtLoginID.Handle, EM_SETCUEBANNER, 0, "login");
            SendMessage(txtPassword.Handle, EM_SETCUEBANNER, 0, "login now");
            SendMessage(txtPIN.Handle, EM_SETCUEBANNER, 0, "wow");

            SendMessage(txtLoginID.Handle, EM_SETCUEBANNER, 0, "login");
            SendMessage(txtPassword.Handle, EM_SETCUEBANNER, 0, "login now");
            SendMessage(txtPIN.Handle, EM_SETCUEBANNER, 0, "wow");

Hi Jassim,

Thank you for posting on this forum.

I tried your code, yes, it shows without error. It seems it works well.

So what do you mean "cue banner not working"?

Best regards,

by cue banner not working I mean cue text is not showing and no error thrown.

I just forgot to mention I am using TextEdit from DevXpress.
