Error: "No value given for one or more required parameters

I keep getting the error "No value given for one or more required
parameters", but not sure why. Can anyone please look at my code snipet
and see if you see any reason why I could be getting this error. I am
just trying to update a record using MS Access 2003 as the front end.
This code is in VB.NET

Private Sub cmdUpdate_Click ()
On Error GoTo Err_cmdUpdate_C lick

Dim rstUsers As New ADODB.Recordset
Dim fld As ADODB.Field
Dim strField As String
Dim strSQL As String
strSQL = "select dbo_tbl_Users.* from dbo_tbl_Users " & "where
dbo_tbl_Users!E mpRec=" & "'" & Me.cboEmpRec & "'"
rstUsers.Open strSQL, CurrentProject. Connection, adOpenKeyset,
adLockOptimisti c
If Not IsNull(Me.cboEm pRec.value) Then
rstUsers!EmpRec = Me.cboEmpRec.va lue
End If

If Not IsNull(Me.txtEm pID) Then
rstUsers!EmpID = Me.txtEmpID
Else
MsgBox "Please enter an employee number", vbOKOnly
GoTo Exit_cmdUpdate_ Click
End If
If Not IsNull(Me.txtEm pName) Then
rstUsers!EmpNam e = Me.txtEmpName
Else
MsgBox "Please enter an employee name", vbOKOnly
GoTo Exit_cmdUpdate_ Click
End If

If Not IsNull(Me.cboSt atus.value) Then
rstUsers!Status = Me.cboStatus.va lue
Else

GoTo Exit_cmdUpdate_ Click
End If

If Not IsNull(Me.txtUN ame) Then
rstUsers!UserNa me = Me.txtUName
Else
MsgBox "Please enter a user name for the employee", vbOKOnly
GoTo Exit_cmdUpdate_ Click
End If

If Not IsNull(Me.txtPa ss) Then
rstUsers!Passwo rd = Me.txtPass
Else
MsgBox "Please enter a password for the employee", vbOKOnly
GoTo Exit_cmdUpdate_ Click
End If

rstUsers.Update
rstUsers.Close

MsgBox "Employee Record has been updated successfully.", vbOKOnly
DoCmd.Close
cboEmpRec = Null

I have created a simple Client-side SOAP Extension for a webclass that I have. When I apply the extension attribute to the the calling function in the proxy class I get an error 'Value cannot be null'. When the extension attribute is not applied it runs fine. The wierd thing is that it does not appear to be an error within the SOAP extension because I break-pointed it and when the proxy function gets called the SOAP extension runs fine....

Hello again, Sorry to bother but I guess my C++ book isn't very good since it obviously contains errors so the program code doesn't work with g++. However I don't understand what the problem is. Last time the problem was that "using namespace std" apparently had a "link" class/object defined already. Now I get: error: no matching function for call to 'String::String(String)'
