Help with "Error 1 Overload resolution failed because no accessible 'find' ..."

[Tech Geek 7331]

Hi there, I've been working on my own version of Notepad/Wordpad and I just tried adding the Find feature for the Rich Text box and I got an error. Here's the code I had:

    Private Sub FindToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FindToolStripMenuItem.Click
        RichTextBox1.Find()
    End Sub

And here's the error:

Error	1	Overload resolution failed because no accessible 'Find' accepts this number of arguments.	C:\Users\Jake\documents\visual studio 2010\Projects\Rich Text Application\Rich Text Application\Form1.vb	82	9	Rich Text Application

Please help me with how to fix this!
Thanks,
Jake
