Run time error '3021' message

[Ovees]

Am currently working with VB 6.0 and Win7 OS. My application is linked with Microsoft Access 2007 (2002-2003 file format) database and whenever I want to update a record in a table from the Access database the project will display a message "Run-time error '3021' Either BOF or EOF is true, or the current record has been deleted. Requested operation requires a current record."
The challenge I have is on line 10 that's where my project halts. Would there be any approach I can use to continue with my project. Below is the code for update procedure.

Private Sub updateButton_Click()
   If rs.State = adStateOpen Then rs.Close
   Con.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\NDASS.mdb"
   rs.Open "SELECT*FROM Details where RegNumber='" & txtSearch.Text & "'", _
                Con, adOpenKeyset, adLockPessimistic
   If rs.BOF Or rs.EOF = True Then
      rs.update
      txtRegNo.Text = rs![RegNumber]
      txtSurname.Text = rs!Surname
      txtMiddleName.Text = rs!MiddleName
      txtOtherName.Text = rs!Othernames
      cboDOB1.Text = rs!DOB1
      cboDOB2.Text = rs!DOB2
      cboDOB3.Text = rs!DOB3
      imgPassport.Picture = LoadPicture(rs!Passport)
      '
      txtCivilianPersonnelName.Text = rs!CivilianPersonnelName
      txtOffBusAddress.Text = rs!civilianOfficeBusinessAddress
      txtEmailNDACivilian.Text = rs!CivilianEmail
      txtPhoneNDACivilian.Text = rs!CivilianPhoneNumber
      cboClassApplied.Text = rs!ClassApplied
      cboSpecialDisability.Text = rs!SpecialDisability
      '
      rs.Update
      MsgBox "Record updated!", vbOKOnly + vbInformation, "Modify"
   End If
   rs.Close
   Set rs = Nothing
   '
   Con.Close
   Set Con = Nothing
End Sub

line 8 in code block should be rs.edit
This will still error if the connection is bad or there isn't a currently selected record.

Line 7 doesn't make sense... you're editing the BOF (first record) or the EOF (last record)?

The remaining code makes no sense in that it appears that you are changing the values of controls on the form, not copying values from the controls to the records.

Thanks for your response. I still don't get it clear how can I modify the values in a control and then update it to a database please

[zmbd]

Let's just look at line 8 in the OP code block:
txtRegNo.Text = rs![RegNumber]

In "english" what you are saying by this code is (in simple terms):
With the control named "txtRegNo" let the property of that control named "Text" have the value of the field [RegNumber] in the recordset assigned to "rs"

where what you need is:
rs![RegNumber] = txtRegNo.Text
let the field [RegNumber] in the recordset assigned to "RS" have the value taken from the property named "Text" from the control named "txtRegNo".
