TextBox.text to crystal report's text object

Can anyone tell me how to insert a form's textbox.text to Crystal report text object?

VB Code:

Dim rptTicket As New Ticket()
        Dim txtObject As TextObject
        If TypeOf (rptTicket.ReportDefinition.ReportObjects.Item("txtTickets")) Is TextObject Then
            txtObject = rptTicket.ReportDefinition.ReportObjects.Item("txtTickets")
            MsgBox(txtObject.Text)
            'txtObject.Text="Cool. Isn't it."
        End If
        'MsgBox(rptTicket.DataDefinition.FormulaFields.Item("AgentCompany").Text())
