ENTER = Activate?

In the following code, I have a find sub... when the user enters a date and hits the "Enter" key, is there a way to bypass the "Ok" key?


Private Sub cmdFind_Click()
Dim ws As Worksheet, myDate
Dim rFoundDate As Range

'check for valid distribution date (between October 1, 2006 thru December 31, 2014)
myDate = txtFindMyDate
With myDate
If DateValue(txtFindMyDate) < DateValue("10/1/2006") Or DateValue(txtFindMyDate) > DateValue("12/11/2014") Then
MsgBox "Please enter a date between October 2006 and December 2014"
.SetFocus
Exit Sub
End If
End With

Cells.Find(What:=txtFindMyDate, After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False).Activate

ActiveCell.Select
Unload Me
End Sub
