Dim sQuery As String = "SELECT Cards.CardNo AS [Card No], Personnel.Name AS [Name], Cards.Expiry_Date AS [Expiry Date], " & _"Cards.AccTag AS [Door Access Rights], Cards.LiftAccTag AS [Lift Access Rights], CP_Card.SendBit " & _"FROM Cards LEFT OUTER JOIN Personnel ON Cards.StaffNo = Personnel.StaffNo " & _"LEFT OUTER JOIN CP_Card ON Cards.CardNo = CP_Card.CardNo " & _"ORDER BY Cards.CardNo "



Dim dsBlock_Ext As New DataSet()

Try


If Not DBClass.ExecuteSQLTable(sQuery, dsBlock_Ext) Then

MsgBox(LOG.WriteErrLog(0,

Exit SubEnd If



With dsBlock_Ext.Tables(0)

Columns.Add("Car Park Access Rights"

If .Rows.Count > 0 ThenReDim aStfNo(.Rows.Count - 1)
ReDim aCardNo(.Rows.Count - 1)

For icnt As Integer = 0 To .Rows.Count - 1
        
For jcnt As Integer = 0 To .Columns.Count - 1If jcnt = 0 Then
        
aCardNo(icnt) = Trim(.Rows(icnt).Item(jcnt))


        ElseIf jcnt = 1 Then
                
.Rows(icnt).Item(jcnt) = Trim(.Rows(icnt).Item(jcnt))


        ElseIf jcnt = 2 Then
                
.Rows(icnt).Item(jcnt) = Mid(.Rows(icnt).Item(jcnt), 7, 2) & "/" & _

                                                Mid(.Rows(icnt).Item(jcnt), 5, 2) & "/" & _

                                                Mid(.Rows(icnt).Item(jcnt), 1, 4


                .Rows(icnt).Item(jcnt) = GetDoorAccess(Trim(.Rows(icnt).Item(0)))


           ElseIf jcnt = 3 Then            ElseIf jcnt = 4 Then


                If .Rows(icnt).Item(jcnt) Is Convert.DBNull Then

                        .Rows(icnt).Item(jcnt) =

                        Else                End If


                ElseIf jcnt = .Columns.Count - 2 Then


                        If .Rows(icnt).Item(jcnt) Is Convert.DBNull Then

                        .Rows(icnt).Item(jcnt + 1) =

                        Else

                        .Rows(icnt).Item(jcnt + 1) = GetCPAccess(Trim(.Rows(icnt).Item(0)))


                        End If

dgvBlock_Extend.DataSource = dsBlock_Ext.Tables(0)




Catch ex As Exception
